- * These macros are used to express state changes in easily readable form.
- *
- * The NS macros expand to a mask and a value, that can be bit ored onto the
- * current state as soon as the spinlock (req_lock) was taken.
- *
- * The _NS macros are used for state functions that get called with the
- * spinlock. These macros expand directly to the new state value.
- *
- * Besides the basic forms NS() and _NS() additional _?NS[23] are defined
- * to express state changes that affect more than one aspect of the state.
- *
- * E.g. NS2(conn, C_CONNECTED, peer, R_SECONDARY)
- * Means that the network connection was established and that the peer
- * is in secondary role.

+ * DOC: DRBD State macros
+ *
+ * These macros are used to express state changes in easily readable form.
+ *
+ * The NS macros expand to a mask and a value, that can be bit ored onto the
+ * current state as soon as the spinlock (req_lock) was taken.
+ *
+ * The _NS macros are used for state functions that get called with the
+ * spinlock. These macros expand directly to the new state value.
+ *
+ * Besides the basic forms NS() and _NS() additional _?NS[23] are defined
+ * to express state changes that affect more than one aspect of the state.
+ *
+ * E.g. NS2(conn, C_CONNECTED, peer, R_SECONDARY)
+ * Means that the network connection was established and that the peer
+ * is in secondary role.

+ * However, after much experimentation, it appears that:
+ * a) normal buses automatically clear BUSY and transition from
+ * Master->Slave when they complete generating a STOP condition.
+ * Therefore, step (3) can be done in doxfer() by polling I2CCON.4

+ * b) HDMIPHY bus does neither, so there is no way to do step 3.
+ * There is no indication when this bus has finished generating
+ * STOP.
+ *
+ * In fact, we have found that as soon as the IRQPEND bit is cleared in
+ * step 2, the HDMIPHY bus generates the STOP condition, and then
+ * immediately starts transferring another data byte, even though the
+ * bus is supposedly stopped. This is presumably because the bus is
+ * still in "Master" mode, and its BUSY bit is still set.
+ *
+ * To avoid these extra post-STOP transactions on HDMI phy devices, we
+ * just disable Serial Output on the bus (I2CSTAT.4 = 0) directly,
+ * instead of first generating a proper STOP condition. This should
+ * float SDA & SCK terminating the transfer. Subsequent transfers
+ * start with a proper START condition, and proceed normally.
+ *
+ * The HDMIPHY bus is an internal bus that always has exactly two
+ * devices, the host as Master and the HDMIPHY device as the slave.
+ * Skipping the STOP condition has been tested on this bus and works.

-/*
- This is the AT91 MCI driver that has been tested with both MMC cards
- and SD-cards. Boards that support write protect are now supported.
- The CCAT91SBC001 board does not support SD cards.
-
- The three entry points are at91_mci_request, at91_mci_set_ios
- and at91_mci_get_ro.
-
- SET IOS
- This configures the device to put it into the correct mode and clock speed
- required.
-
- MCI REQUEST
- MCI request processes the commands sent in the mmc_request structure. This
- can consist of a processing command and a stop command in the case of
- multiple block transfers.
-
- There are three main types of request, commands, reads and writes.
-
- Commands are straight forward. The command is submitted to the controller and
- the request function returns. When the controller generates an interrupt to indicate
- the command is finished, the response to the command are read and the mmc_request_done
- function called to end the request.
-
- Reads and writes work in a similar manner to normal commands but involve the PDC (DMA)
- controller to manage the transfers.
-
- A read is done from the controller directly to the scatterlist passed in from the request.
- Due to a bug in the AT91RM9200 controller, when a read is completed, all the words are byte
- swapped in the scatterlist buffers. AT91SAM926x are not affected by this bug.
-
- The sequence of read interrupts is: ENDRX, RXBUFF, CMDRDY
-
- A write is slightly different in that the bytes to write are read from the scatterlist
- into a dma memory buffer (this is in case the source buffer should be read only). The
- entire write buffer is then done from this single dma memory buffer.
-
- The sequence of write interrupts is: ENDTX, TXBUFE, NOTBUSY, CMDRDY
-
- GET RO
- Gets the status of the write protect pin, if available.

- * The hash address register is 64 bits long and takes up two locations in the memory map.

- * The unicast hash enable and the multicast hash enable bits in the network configuration
- * register enable the reception of hash matched frames. The destination address is
- * reduced to a 6 bit index into the 64 bit hash register using the following hash function.
- * The hash function is an exclusive or of every sixth bit of the destination address.
- * hash_index[5] = da[5] ^ da[11] ^ da[17] ^ da[23] ^ da[29] ^ da[35] ^ da[41] ^ da[47]

- * da[0] represents the least significant bit of the first byte received, that is, the multicast/
- * unicast indicator, and da[47] represents the most significant bit of the last byte
- * received.
- * If the hash index points to a bit that is set in the hash register then the frame will be
- * matched according to whether the frame is multicast or unicast.
- * A multicast match will be signalled if the multicast hash enable bit is set, da[0] is 1 and
- * the hash index points to a bit set in the hash register.
- * A unicast match will be signalled if the unicast hash enable bit is set, da[0] is 0 and the

* Notes on locking strategy:

- * Most CSRs are 128-bit (oword) and therefore cannot be read or
- * written atomically. Access from the host is buffered by the Bus
- * Interface Unit (BIU). Whenever the host reads from the lowest
- * address of such a register, or from the address of a different such
- * register, the BIU latches the register's value. Subsequent reads
- * from higher addresses of the same register will read the latched
- * value. Whenever the host writes part of such a register, the BIU
- * collects the written value and does not write to the underlying
- * register until all 4 dwords have been written. A similar buffering
- * scheme applies to host access to the NIC's 64-bit SRAM.
+ * Many CSRs are very wide and cannot be read or written atomically.
+ * Writes from the host are buffered by the Bus Interface Unit (BIU)
+ * up to 128 bits. Whenever the host writes part of such a register,
+ * the BIU collects the written value and does not write to the
+ * underlying register until all 4 dwords have been written. A
+ * similar buffering scheme applies to host access to the NIC's 64-bit
+ * SRAM.
*
- * Access to different CSRs and 64-bit SRAM words must be serialised,
- * since interleaved access can result in lost writes or lost
- * information from read-to-clear fields. We use efx_nic::biu_lock
- * for this. (We could use separate locks for read and write, but

+/**
+ * WMI event receiving - theory of operations
+ *
+ * When firmware about to report WMI event, it fills memory area
+ * in the mailbox and raises misc. IRQ. Thread interrupt handler invoked for
+ * the misc IRQ, function @wmi_recv_cmd called by thread IRQ handler.
+ *
+ * @wmi_recv_cmd reads event, allocates memory chunk and attaches it to the
+ * event list @wil->pending_wmi_ev. Then, work queue @wil->wmi_wq wakes up
+ * and handles events within the @wmi_event_worker. Every event get detached
+ * from list, processed and deleted.
+ *
+ * Purpose for this mechanism is to release IRQ thread; otherwise,
+ * if WMI event handling involves another WMI command flow, this 2-nd flow
+ * won't be completed because of blocked IRQ thread.

+/**
+ * Addressing - theory of operations
+ *
+ * There are several buses present on the WIL6210 card.
+ * Same memory areas are visible at different address on
+ * the different busses. There are 3 main bus masters:
+ * - MAC CPU (ucode)
+ * - User CPU (firmware)
+ * - AHB (host)
+ *
+ * On the PCI bus, there is one BAR (BAR0) of 2Mb size, exposing
+ * AHB addresses starting from 0x880000
+ *
+ * Internally, firmware uses addresses that allows faster access but
+ * are invisible from the host. To read from these addresses, alternative
+ * AHB address must be used.

+ * Version History
+ * ---------------
+ *
+ * Date Version Description
+ * -------- -------- ------------------------------------------------------
+ * 04-30-07 02.00.00 Corresponds to Fusion-MPT MPI Specification Rev A.
+ * 10-31-07 02.00.01 Fixed name for pMpi2SCSITaskManagementRequest_t.
+ * 12-18-07 02.00.02 Modified Task Management Target Reset Method defines.
+ * 02-29-08 02.00.03 Added Query Task Set and Query Unit Attention.
+ * 03-03-08 02.00.04 Fixed name of struct _MPI2_SCSI_TASK_MANAGE_REPLY.
+ * 05-21-08 02.00.05 Fixed typo in name of Mpi2SepRequest_t.
+ * 10-02-08 02.00.06 Removed Untagged and No Disconnect values from SCSI IO
+ * Control field Task Attribute flags.
+ * Moved LUN field defines to mpi2.h becasue they are
+ * common to many structures.
+ * 05-06-09 02.00.07 Changed task management type of Query Unit Attention to
+ * Query Asynchronous Event.
+ * Defined two new bits in the SlotStatus field of the SCSI
+ * Enclosure Processor Request and Reply.
+ * 10-28-09 02.00.08 Added defines for decoding the ResponseInfo bytes for
+ * both SCSI IO Error Reply and SCSI Task Management Reply.
+ * Added ResponseInfo field to MPI2_SCSI_TASK_MANAGE_REPLY.
+ * Added MPI2_SCSITASKMGMT_RSP_TM_OVERLAPPED_TAG define.
+ * 02-10-10 02.00.09 Removed unused structure that had "#if 0" around it.
+ * 05-12-10 02.00.10 Added optional vendor-unique region to SCSI IO Request.
+ * 11-10-10 02.00.11 Added MPI2_SCSIIO_NUM_SGLOFFSETS define.
+ * 11-18-11 02.00.12 Incorporating additions for MPI v2.5.
+ * 02-06-12 02.00.13 Added alternate defines for Task Priority / Command
+ * Priority to match SAM-4.
+ * Added EEDPErrorOffset to MPI2_SCSI_IO_REPLY.
+ * 07-10-12 02.00.14 Added MPI2_SCSIIO_CONTROL_SHIFT_DATADIRECTION.

- [1] - IRQ (optional, but commands won't work without it)
-
-Configuration options - PCI215, PCI272:
- [0] - PCI bus of device (optional)
- [1] - PCI slot of device (optional)
- If bus/slot is not specified, the first available PCI device will
- be used.
-
-Passing a zero for an option is the same as leaving it unspecified.

-Each PPI is a 8255 chip providing 24 DIO channels. The DIO channels
-are configurable as inputs or outputs in four groups:
-
- Port A - channels 0 to 7
- Port B - channels 8 to 15
- Port CL - channels 16 to 19
- Port CH - channels 20 to 23
-
-Only mode 0 of the 8255 chips is supported.
-
-Each CTR is a 8254 chip providing 3 16-bit counter channels. Each
-channel is configured individually with INSN_CONFIG instructions. The
-specific type of configuration instruction is specified in data[0].
-Some configuration instructions expect an additional parameter in
-data[1]; others return a value in data[1]. The following configuration
-instructions are supported:
-
- INSN_CONFIG_SET_COUNTER_MODE. Sets the counter channel's mode and
- BCD/binary setting specified in data[1].
-
- INSN_CONFIG_8254_READ_STATUS. Reads the status register value for the
- counter channel into data[1].
-
- INSN_CONFIG_SET_CLOCK_SRC. Sets the counter channel's clock source as
- specified in data[1] (this is a hardware-specific value). Not
- supported on PC214E. For the other boards, valid clock sources are
- 0 to 7 as follows:
-
- 0. CLK n, the counter channel's dedicated CLK input from the SK1
- connector. (N.B. for other values, the counter channel's CLKn
- pin on the SK1 connector is an output!)
- 1. Internal 10 MHz clock.
- 2. Internal 1 MHz clock.
- 3. Internal 100 kHz clock.
- 4. Internal 10 kHz clock.
- 5. Internal 1 kHz clock.
- 6. OUT n-1, the output of counter channel n-1 (see note 1 below).
- 7. Ext Clock, the counter chip's dedicated Ext Clock input from
- the SK1 connector. This pin is shared by all three counter
- channels on the chip.
-
- INSN_CONFIG_GET_CLOCK_SRC. Returns the counter channel's current
- clock source in data[1]. For internal clock sources, data[2] is set
- to the period in ns.
-
- INSN_CONFIG_SET_GATE_SRC. Sets the counter channel's gate source as
- specified in data[2] (this is a hardware-specific value). Not
- supported on PC214E. For the other boards, valid gate sources are 0
- to 7 as follows:
-
- 0. VCC (internal +5V d.c.), i.e. gate permanently enabled.
- 1. GND (internal 0V d.c.), i.e. gate permanently disabled.
- 2. GAT n, the counter channel's dedicated GAT input from the SK1
- connector. (N.B. for other values, the counter channel's GATn
- pin on the SK1 connector is an output!)
- 3. /OUT n-2, the inverted output of counter channel n-2 (see note
- 2 below).
- 4. Reserved.
- 5. Reserved.
- 6. Reserved.
- 7. Reserved.
-
- INSN_CONFIG_GET_GATE_SRC. Returns the counter channel's current gate
- source in data[2].
-
-Clock and gate interconnection notes:
-
- 1. Clock source OUT n-1 is the output of the preceding channel on the
- same counter subdevice if n > 0, or the output of channel 2 on the
- preceding counter subdevice (see note 3) if n = 0.
-
- 2. Gate source /OUT n-2 is the inverted output of channel 0 on the
- same counter subdevice if n = 2, or the inverted output of channel n+1
- on the preceding counter subdevice (see note 3) if n < 2.
-
- 3. The counter subdevices are connected in a ring, so the highest
- counter subdevice precedes the lowest.
-
-The 'INTERRUPT' subdevice pretends to be a digital input subdevice. The
-digital inputs come from the interrupt status register. The number of
-channels matches the number of interrupt sources. The PC214E does not
-have an interrupt status register; see notes on 'INTERRUPT SOURCES'
-below.

-
-When an interrupt source is enabled in the interrupt source enable
-register, a rising edge on the source signal latches the corresponding
-bit to 1 in the interrupt status register.
-
-When the interrupt status register value as a whole (actually, just the
-6 least significant bits) goes from zero to non-zero, the board will
-generate an interrupt. For level-triggered hardware interrupts (PCI
-card), the interrupt will remain asserted until the interrupt status
-register is cleared to zero. For edge-triggered hardware interrupts
-(ISA card), no further interrupts will occur until the interrupt status
-register is cleared to zero. To clear a bit to zero in the interrupt
-status register, the corresponding interrupt source must be disabled
-in the interrupt source enable register (there is no separate interrupt
-clear register).
-
-The PC214E does not have an interrupt source enable register or an
-interrupt status register; its 'INTERRUPT' subdevice has a single
-channel and its interrupt source is selected by the position of jumper
-J5.
-
-COMMANDS
-
-The driver supports a read streaming acquisition command on the
-'INTERRUPT' subdevice. The channel list selects the interrupt sources
-to be enabled. All channels will be sampled together (convert_src ==
-TRIG_NOW). The scan begins a short time after the hardware interrupt
-occurs, subject to interrupt latencies (scan_begin_src == TRIG_EXT,
-scan_begin_arg == 0). The value read from the interrupt status register
-is packed into a short value, one bit per requested channel, in the
-order they appear in the channel list.

+ * Driver: amplc_dio200
+ * Description: Amplicon 200 Series Digital I/O
+ * Author: Ian Abbott <abbotti@mev.co.uk>
+ * Devices: [Amplicon] PC212E (pc212e), PC214E (pc214e), PC215E (pc215e),
+ * PCI215 (pci215), PCIe215 (pcie215), PC218E (pc218e), PCIe236 (pcie236),
+ * PC272E (pc272e), PCI272 (pci272), PCIe296 (pcie296)
+ * Updated: Wed, 24 Oct 2012 16:22:34 +0100
+ * Status: works
+ *
+ * Configuration options - PC212E, PC214E, PC215E, PC218E, PC272E:
+ * [0] - I/O port base address
+ * [1] - IRQ (optional, but commands won't work without it)
+ *
+ * Manual configuration of PCI(e) cards is not supported; they are configured
+ * automatically.
+ *
+ * Passing a zero for an option is the same as leaving it unspecified.

+ * Each PPI is a 8255 chip providing 24 DIO channels. The DIO channels
+ * are configurable as inputs or outputs in four groups:
+ *
+ * Port A - channels 0 to 7
+ * Port B - channels 8 to 15
+ * Port CL - channels 16 to 19
+ * Port CH - channels 20 to 23
+ *
+ * Only mode 0 of the 8255 chips is supported.
+ *
+ * Each CTR is a 8254 chip providing 3 16-bit counter channels. Each
+ * channel is configured individually with INSN_CONFIG instructions. The
+ * specific type of configuration instruction is specified in data[0].
+ * Some configuration instructions expect an additional parameter in
+ * data[1]; others return a value in data[1]. The following configuration
+ * instructions are supported:
+ *
+ * INSN_CONFIG_SET_COUNTER_MODE. Sets the counter channel's mode and
+ * BCD/binary setting specified in data[1].
+ *
+ * INSN_CONFIG_8254_READ_STATUS. Reads the status register value for the
+ * counter channel into data[1].
+ *
+ * INSN_CONFIG_SET_CLOCK_SRC. Sets the counter channel's clock source as
+ * specified in data[1] (this is a hardware-specific value). Not
+ * supported on PC214E. For the other boards, valid clock sources are
+ * 0 to 7 as follows:
+ *
+ * 0. CLK n, the counter channel's dedicated CLK input from the SK1
+ * connector. (N.B. for other values, the counter channel's CLKn
+ * pin on the SK1 connector is an output!)
+ * 1. Internal 10 MHz clock.
+ * 2. Internal 1 MHz clock.
+ * 3. Internal 100 kHz clock.
+ * 4. Internal 10 kHz clock.
+ * 5. Internal 1 kHz clock.
+ * 6. OUT n-1, the output of counter channel n-1 (see note 1 below).
+ * 7. Ext Clock, the counter chip's dedicated Ext Clock input from
+ * the SK1 connector. This pin is shared by all three counter
+ * channels on the chip.
+ *
+ * For the PCIe boards, clock sources in the range 0 to 31 are allowed
+ * and the following additional clock sources are defined:
+ *
+ * 8. HIGH logic level.
+ * 9. LOW logic level.
+ * 10. "Pattern present" signal.
+ * 11. Internal 20 MHz clock.
+ *
+ * INSN_CONFIG_GET_CLOCK_SRC. Returns the counter channel's current
+ * clock source in data[1]. For internal clock sources, data[2] is set
+ * to the period in ns.
+ *
+ * INSN_CONFIG_SET_GATE_SRC. Sets the counter channel's gate source as
+ * specified in data[2] (this is a hardware-specific value). Not
+ * supported on PC214E. For the other boards, valid gate sources are 0
+ * to 7 as follows:
+ *
+ * 0. VCC (internal +5V d.c.), i.e. gate permanently enabled.
+ * 1. GND (internal 0V d.c.), i.e. gate permanently disabled.
+ * 2. GAT n, the counter channel's dedicated GAT input from the SK1
+ * connector. (N.B. for other values, the counter channel's GATn
+ * pin on the SK1 connector is an output!)
+ * 3. /OUT n-2, the inverted output of counter channel n-2 (see note
+ * 2 below).
+ * 4. Reserved.
+ * 5. Reserved.
+ * 6. Reserved.
+ * 7. Reserved.
+ *
+ * For the PCIe boards, gate sources in the range 0 to 31 are allowed;
+ * the following additional clock sources and clock sources 6 and 7 are
+ * (re)defined:
+ *
+ * 6. /GAT n, negated version of the counter channel's dedicated
+ * GAT input (negated version of gate source 2).
+ * 7. OUT n-2, the non-inverted output of counter channel n-2
+ * (negated version of gate source 3).
+ * 8. "Pattern present" signal, HIGH while pattern present.
+ * 9. "Pattern occurred" latched signal, latches HIGH when pattern
+ * occurs.
+ * 10. "Pattern gone away" latched signal, latches LOW when pattern
+ * goes away after it occurred.
+ * 11. Negated "pattern present" signal, LOW while pattern present
+ * (negated version of gate source 8).
+ * 12. Negated "pattern occurred" latched signal, latches LOW when
+ * pattern occurs (negated version of gate source 9).
+ * 13. Negated "pattern gone away" latched signal, latches LOW when
+ * pattern goes away after it occurred (negated version of gate
+ * source 10).
+ *
+ * INSN_CONFIG_GET_GATE_SRC. Returns the counter channel's current gate
+ * source in data[2].
+ *
+ * Clock and gate interconnection notes:
+ *
+ * 1. Clock source OUT n-1 is the output of the preceding channel on the
+ * same counter subdevice if n > 0, or the output of channel 2 on the
+ * preceding counter subdevice (see note 3) if n = 0.
+ *
+ * 2. Gate source /OUT n-2 is the inverted output of channel 0 on the
+ * same counter subdevice if n = 2, or the inverted output of channel n+1
+ * on the preceding counter subdevice (see note 3) if n < 2.
+ *
+ * 3. The counter subdevices are connected in a ring, so the highest
+ * counter subdevice precedes the lowest.
+ *
+ * The 'TIMER' subdevice is a free-running 32-bit timer subdevice.
+ *
+ * The 'INTERRUPT' subdevice pretends to be a digital input subdevice. The
+ * digital inputs come from the interrupt status register. The number of
+ * channels matches the number of interrupt sources. The PC214E does not
+ * have an interrupt status register; see notes on 'INTERRUPT SOURCES'
+ * below.

+ *
+ * When an interrupt source is enabled in the interrupt source enable
+ * register, a rising edge on the source signal latches the corresponding
+ * bit to 1 in the interrupt status register.
+ *
+ * When the interrupt status register value as a whole (actually, just the
+ * 6 least significant bits) goes from zero to non-zero, the board will
+ * generate an interrupt. For level-triggered hardware interrupts (PCI
+ * card), the interrupt will remain asserted until the interrupt status
+ * register is cleared to zero. For edge-triggered hardware interrupts
+ * (ISA card), no further interrupts will occur until the interrupt status
+ * register is cleared to zero. To clear a bit to zero in the interrupt
+ * status register, the corresponding interrupt source must be disabled
+ * in the interrupt source enable register (there is no separate interrupt
+ * clear register).
+ *
+ * The PC214E does not have an interrupt source enable register or an
+ * interrupt status register; its 'INTERRUPT' subdevice has a single
+ * channel and its interrupt source is selected by the position of jumper
+ * J5.

+ * COMMANDS

+ * The driver supports a read streaming acquisition command on the

+ * to be enabled. All channels will be sampled together (convert_src ==
+ * TRIG_NOW). The scan begins a short time after the hardware interrupt
+ * occurs, subject to interrupt latencies (scan_begin_src == TRIG_EXT,
+ * scan_begin_arg == 0). The value read from the interrupt status register
+ * is packed into a short value, one bit per requested channel, in the
+ * order they appear in the channel list.

- NAME
- CsrLogLevelTextSet
-
- DESCRIPTION
- Set the text logging level for a given origin and optionally sub origin
- by name. If either string is NULL or zero length, it is interpreted as
- all origins and/or all sub origins respectively. If originName is NULL
- or zero length, subOriginName is ignored.
-
- Passing NULL or zero length strings in both originName and subOriginName
- is equivalent to calling CsrLogLevelTextSetAll, and overrides all
- previous filter configurations for all origins and sub origins.
-
- Passing NULL or a zero length string in subOriginName overrides all
- previous filter configurations for all sub origins of the specified
- origin.
-
- Note: the supplied strings may be accessed after the function returns
- and must remain valid and constant until CsrLogDeinit is called.
-
- Note: when specifying an origin (originName is not NULL and not zero
- length), this function can only be used for origins that use the
- csr_log_text_2.h interface for registration and logging. Filtering for
- origins that use the legacy csr_log_text.h interface must be be
- configured using the legacy filter configuration functions that accept
- a CsrLogTextTaskId as origin specifier. However, when not specifying an
- origin this function also affects origins that have been registered with
- the legacy csr_log_text.h interface. Furthermore, using this function
- and the legacy filter configuration functions on the same origin is not
- allowed.
-
- PARAMETERS
- originName - a string containing the name of the origin. Can be NULL or
- zero length to set the log level for all origins. In this case, the
- subOriginName parameter will be ignored.
- subOriginName - a string containing the name of the sub origin. Can be
- NULL or zero length to set the log level for all sub origins of the
- specified origin.
- warningLevelMask - The desired log level for the specified origin(s) and
- sub origin(s).

+ help
+ This enables TTY over IEEE 1394, providing high-speed serial
+ connectivity to cabled peers. This driver implements a
+ ad-hoc transport protocol and is currently limited to
+ Linux-to-Linux communication.
+
+ To compile this driver as a module, say M here: the module will
+ be called firewire-serial.

+TODOs prior to this driver moving out of staging
+------------------------------------------------
+1. Implement retries for RCODE_BUSY, RCODE_NO_ACK and RCODE_SEND_ERROR
+ - I/O is handled asynchronously which presents some issues when error
+ conditions occur.
+2. Implement _robust_ console on top of this. The existing prototype console
+ driver is not ready for the big leagues yet.
+3. Expose means of controlling attach/detach of peers via sysfs. Include
+ GUID-to-port matching/whitelist/blacklist.
+
+-- Issues with firewire stack --
+1. This driver uses the same unregistered vendor id that the firewire core does
+ (0xd00d1e). Perhaps this could be exposed as a define in
+ firewire.h?
+3. Maybe device_max_receive() and link_speed_to_max_payload() should be
+ taken up by the firewire core?
+
+-- Issues with TTY core --
+ 1. Hack for alternate device name scheme
+ - because udev no longer allows device renaming, devices should have
+ their proper names on creation. This is an issue for creating the
+ fwloop<n> device with the fwtty<n> devices because although duplicating
+ roughly the same operations as tty_port_register_device() isn't difficult,
+ access to the tty_class & tty_fops is restricted in scope.
+
+ This is currently being worked around in create_loop_device() by
+ extracting the tty_class ptr and tty_fops ptr from the previously created
+ tty devices. Perhaps an add'l api can be added -- eg.,
+ tty_{port_}register_named_device().

+/**
+ * The design basis for the DMA FIFO is to provide an output side that
+ * complies with the streaming DMA API design that can be DMA'd from directly
+ * (without additional copying), coupled with an input side that maintains a
+ * logically consistent 'apparent' size (ie, bytes in + bytes avail is static
+ * for the lifetime of the FIFO).
+ *
+ * DMA output transactions originate on a cache line boundary and can be
+ * variably-sized. DMA output transactions can be retired out-of-order but
+ * the FIFO will only advance the output in the original input sequence.
+ * This means the FIFO will eventually stall if a transaction is never retired.
+ *
+ * Chunking the output side into cache line multiples means that some FIFO
+ * memory is unused. For example, if all the avail input has been pended out,
+ * then the in and out markers are re-aligned to the next cache line.
+ * The maximum possible waste is
+ * (cache line alignment - 1) * (max outstanding dma transactions)
+ * This potential waste requires additional hidden capacity within the FIFO
+ * to be able to accept input while the 'apparent' size has not been reached.
+ *

+ * fwserial_probe: bus probe function for firewire 'serial' unit devices
+ *
+ * A 'serial' unit device is created and probed as a result of:
+ * - declaring a ieee1394 bus id table for 'devices' matching a fabricated
+ * 'serial' unit specifier id
+ * - adding a unit directory to the config ROM(s) for a 'serial' unit
+ *
+ * The firewire core registers unit devices by enumerating unit directories
+ * of a node's config ROM after reading the config ROM when a new node is
+ * added to the bus topology after a bus reset.
+ *
+ * The practical implications of this are:
+ * - this probe is called for both local and remote nodes that have a 'serial'
+ * unit directory in their config ROM (that matches the specifiers in
+ * fwserial_id_table).
+ * - no specific order is enforced for local vs. remote unit devices
+ *
+ * This unit driver copes with the lack of specific order in the same way the
+ * firewire net driver does -- each probe, for either a local or remote unit
+ * device, is treated as a 'peer' (has a struct fwtty_peer instance) and the
+ * first peer created for a given fw_card (tracked by the global fwserial_list)
+ * creates the underlying TTYs (aggregated in a fw_serial instance).
+ *
+ * NB: an early attempt to differentiate local & remote unit devices by creating
+ * peers only for remote units and fw_serial instances (with their
+ * associated TTY devices) only for local units was discarded. Managing
+ * the peer lifetimes on device removal proved too complicated.
+ *
+ * fwserial_probe/fwserial_remove are effectively serialized by the
+ * fwserial_list_mutex. This is necessary because the addition of the first peer
+ * for a given fw_card will trigger the creation of the fw_serial for that
+ * fw_card, which must not simultaneously contend with the removal of the
+ * last peer for a given fw_card triggering the destruction of the same
+ * fw_serial for the same fw_card.

+ * @fwcon_ops: ops for attached fw_console (if any)
+ * @con_data: private data for fw_console
+ * @wait_tx: waitqueue for sleeping until writer/drain completes tx
+ * @emit_breaks: delayed work responsible for generating breaks when the
+ * break line status is active
+ * @cps : characters per second computed from the termios settings
+ * @break_last: timestamp in jiffies from last emit_breaks
+ * @hangup: work responsible for HUPing when carrier is dropped/lost

. Revisit GEM sync object infrastructure.. TTM has some framework for this
already. Possibly this could be refactored out and made more common?
There should be some way to do this with less wheel-reinvention.
-. Review DSS vs KMS mismatches. The omap_dss_device is sort of part encoder,
- part connector. Which results in a bit of duct tape to fwd calls from
- encoder to connector. Possibly this could be done a bit better.
. Solve PM sequencing on resume. DMM/TILER must be reloaded before any
access is made from any component in the system. Which means on suspend
CRTC's should be disabled, and on resume the LUT should be reprogrammed

+ * -writes-data-to-uart
+ * -enable-tx-intr
+ *
+ * Once data bits are pushed out, controller raises the Tx-room-avail-Interrupt.
+ * The first thing Tx ISR does is disable further Tx interrupts (as this could
+ * be the last char to send, before settling down into the quiet polled mode).
+ * It then calls the exact routine used by tty layer write to send out any
+ * more char in tty buffer. In case of sending, it re-enables Tx-intr. In case

+ Platform driver for Userspace I/O devices, including generic

+
+ Memory regions can be specified with the same platform device
+ resources as the UIO_PDRV drivers, but dynamic regions can also
+ be specified.
+ The number and size of these regions is static,
+ but the memory allocation is not performed until

- * The File-backed Storage Gadget acts as a USB Mass Storage device,
- * appearing to the host as a disk drive or as a CD-ROM drive. In addition
- * to providing an example of a genuinely useful gadget driver for a USB
- * device, it also illustrates a technique of double-buffering for increased
- * throughput. Last but not least, it gives an easy way to probe the
- * behavior of the Mass Storage drivers in a USB host.
- *
- * Backing storage is provided by a regular file or a block device, specified
- * by the "file" module parameter. Access can be limited to read-only by
- * setting the optional "ro" module parameter. (For CD-ROM emulation,
- * access is always read-only.) The gadget will indicate that it has
- * removable media if the optional "removable" module parameter is set.
- *
- * The gadget supports the Control-Bulk (CB), Control-Bulk-Interrupt (CBI),
- * and Bulk-Only (also known as Bulk-Bulk-Bulk or BBB) transports, selected
- * by the optional "transport" module parameter. It also supports the
- * following protocols: RBC (0x01), ATAPI or SFF-8020i (0x02), QIC-157 (0c03),
- * UFI (0x04), SFF-8070i (0x05), and transparent SCSI (0x06), selected by
- * the optional "protocol" module parameter. In addition, the default
- * Vendor ID, Product ID, release number and serial number can be overridden.
- *
- * There is support for multiple logical units (LUNs), each of which has
- * its own backing file. The number of LUNs can be set using the optional
- * "luns" module parameter (anywhere from 1 to 8), and the corresponding
- * files are specified using comma-separated lists for "file" and "ro".
- * The default number of LUNs is taken from the number of "file" elements;
- * it is 1 if "file" is not given. If "removable" is not set then a backing
- * file must be specified for each LUN. If it is set, then an unspecified
- * or empty backing filename means the LUN's medium is not loaded. Ideally
- * each LUN would be settable independently as a disk drive or a CD-ROM
- * drive, but currently all LUNs have to be the same type. The CD-ROM
- * emulation includes a single data track and no audio tracks; hence there
- * need be only one backing file per LUN.
- *
- * Requirements are modest; only a bulk-in and a bulk-out endpoint are
- * needed (an interrupt-out endpoint is also needed for CBI). The memory
- * requirement amounts to two 16K buffers, size configurable by a parameter.
- * Support is included for both full-speed and high-speed operation.
- *
- * Note that the driver is slightly non-portable in that it assumes a
- * single memory/DMA buffer will be useable for bulk-in, bulk-out, and
- * interrupt-in endpoints. With most device controllers this isn't an
- * issue, but there may be some with hardware restrictions that prevent
- * a buffer from being used by more than one endpoint.
- *
- * Module options:
- *
- * file=filename[,filename...]
- * Required if "removable" is not set, names of
- * the files or block devices used for
- * backing storage
- * serial=HHHH... Required serial number (string of hex chars)
- * ro=b[,b...] Default false, booleans for read-only access
- * removable Default false, boolean for removable media
- * luns=N Default N = number of filenames, number of
- * LUNs to support
- * nofua=b[,b...] Default false, booleans for ignore FUA flag
- * in SCSI WRITE(10,12) commands
- * stall Default determined according to the type of
- * USB device controller (usually true),
- * boolean to permit the driver to halt
- * bulk endpoints
- * cdrom Default false, boolean for whether to emulate
- * a CD-ROM drive
- * transport=XXX Default BBB, transport name (CB, CBI, or BBB)
- * protocol=YYY Default SCSI, protocol name (RBC, 8020 or
- * ATAPI, QIC, UFI, 8070, or SCSI;
- * also 1 - 6)
- * vendor=0xVVVV Default 0x0525 (NetChip), USB Vendor ID
- * product=0xPPPP Default 0xa4a5 (FSG), USB Product ID
- * release=0xRRRR Override the USB release number (bcdDevice)
- * buflen=N Default N=16384, buffer size used (will be
- * rounded down to a multiple of
- * PAGE_CACHE_SIZE)
- *
- * If CONFIG_USB_FILE_STORAGE_TEST is not set, only the "file", "serial", "ro",
- * "removable", "luns", "nofua", "stall", and "cdrom" options are available;
- * default values are used for everything else.
- *
- * The pathnames of the backing files and the ro settings are available in
- * the attribute files "file", "nofua", and "ro" in the lun<n> subdirectory of
- * the gadget's sysfs directory. If the "removable" option is set, writing to
- * these files will simulate ejecting/loading the medium (writing an empty
- * line means eject) and adjusting a write-enable tab. Changes to the ro
- * setting are not allowed when the medium is loaded or if CD-ROM emulation
- * is being used.
- *
- * This gadget driver is heavily based on "Gadget Zero" by David Brownell.
- * The driver's SCSI command interface was based on the "Information
- * technology - Small Computer System Interface - 2" document from
- * X3T9.2 Project 375D, Revision 10L, 7-SEP-93, available at
- * <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>. The single exception
- * is opcode 0x23 (READ FORMAT CAPACITIES), which was based on the
- * "Universal Serial Bus Mass Storage Class UFI Command Specification"
- * document, Revision 1.0, December 14, 1998, available at
- * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>.

-/*
- * Driver Design
- *
- * The FSG driver is fairly straightforward. There is a main kernel
- * thread that handles most of the work. Interrupt routines field
- * callbacks from the controller driver: bulk- and interrupt-request
- * completion notifications, endpoint-0 events, and disconnect events.
- * Completion events are passed to the main thread by wakeup calls. Many
- * ep0 requests are handled at interrupt time, but SetInterface,
- * SetConfiguration, and device reset requests are forwarded to the
- * thread in the form of "exceptions" using SIGUSR1 signals (since they
- * should interrupt any ongoing file I/O operations).
- *
- * The thread's main routine implements the standard command/data/status
- * parts of a SCSI interaction. It and its subroutines are full of tests
- * for pending signals/exceptions -- all this polling is necessary since
- * the kernel has no setjmp/longjmp equivalents. (Maybe this is an
- * indication that the driver really wants to be running in userspace.)
- * An important point is that so long as the thread is alive it keeps an
- * open reference to the backing file. This will prevent unmounting
- * the backing file's underlying filesystem and could cause problems
- * during system shutdown, for example. To prevent such problems, the
- * thread catches INT, TERM, and KILL signals and converts them into
- * an EXIT exception.
- *
- * In normal operation the main thread is started during the gadget's
- * fsg_bind() callback and stopped during fsg_unbind(). But it can also
- * exit when it receives a signal, and there's no point leaving the
- * gadget running when the thread is dead. So just before the thread
- * exits, it deregisters the gadget driver. This makes things a little
- * tricky: The driver is deregistered at two places, and the exiting
- * thread can indirectly call fsg_unbind() which in turn can tell the
- * thread to exit. The first problem is resolved through the use of the
- * REGISTERED atomic bitflag; the driver will only be deregistered once.
- * The second problem is resolved by having fsg_unbind() check
- * fsg->state; it won't try to stop the thread if the state is already
- * FSG_STATE_TERMINATED.
- *
- * To provide maximum throughput, the driver uses a circular pipeline of
- * buffer heads (struct fsg_buffhd). In principle the pipeline can be
- * arbitrarily long; in practice the benefits don't justify having more
- * than 2 stages (i.e., double buffering). But it helps to think of the
- * pipeline as being a long one. Each buffer head contains a bulk-in and
- * a bulk-out request pointer (since the buffer can be used for both
- * output and input -- directions always are given from the host's
- * point of view) as well as a pointer to the buffer and various state
- * variables.
- *
- * Use of the pipeline follows a simple protocol. There is a variable
- * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
- * At any time that buffer head may still be in use from an earlier
- * request, so each buffer head has a state variable indicating whether
- * it is EMPTY, FULL, or BUSY. Typical use involves waiting for the
- * buffer head to be EMPTY, filling the buffer either by file I/O or by
- * USB I/O (during which the buffer head is BUSY), and marking the buffer
- * head FULL when the I/O is complete. Then the buffer will be emptied
- * (again possibly by USB I/O, during which it is marked BUSY) and
- * finally marked EMPTY again (possibly by a completion routine).
- *
- * A module parameter tells the driver to avoid stalling the bulk
- * endpoints wherever the transport specification allows. This is
- * necessary for some UDCs like the SuperH, which cannot reliably clear a
- * halt on a bulk endpoint. However, under certain circumstances the
- * Bulk-only specification requires a stall. In such cases the driver
- * will halt the endpoint and set a flag indicating that it should clear
- * the halt in software during the next device reset. Hopefully this
- * will permit everything to work correctly. Furthermore, although the
- * specification allows the bulk-out endpoint to halt when the host sends
- * too much data, implementing this would cause an unavoidable race.
- * The driver will always use the "no-stall" approach for OUT transfers.
- *
- * One subtle point concerns sending status-stage responses for ep0
- * requests. Some of these requests, such as device reset, can involve
- * interrupting an ongoing file I/O operation, which might take an
- * arbitrarily long time. During that delay the host might give up on
- * the original ep0 request and issue a new one. When that happens the
- * driver should not notify the host about completion of the original
- * request, as the host will no longer be waiting for it. So the driver
- * assigns to each ep0 request a unique tag, and it keeps track of the
- * tag value of the request associated with a long-running exception
- * (device-reset, interface-change, or configuration-change). When the
- * exception handler is finished, the status-stage response is submitted
- * only if the current ep0 request tag is equal to the exception request
- * tag. Thus only the most recently received ep0 request will get a
- * status-stage response.
- *
- * Warning: This driver source file is too long. It ought to be split up
- * into a header file plus about 3 separate .c files, to handle the details
- * of the Gadget, USB Mass Storage, and SCSI protocols.
