2022-02-09peci: Add sysfs interface for PECI busIwona Winiarska5-2/+91
PECI devices may not be discoverable at the time when PECI controller is being added (e.g. BMC can boot up when the Host system is still in S5). Since we currently don't have the capabilities to figure out the Host system state inside the PECI subsystem itself, we have to rely on userspace to do it for us. In the future, PECI subsystem may be expanded with mechanisms that allow us to avoid depending on userspace interaction (e.g. CPU presence could be detected using GPIO, and the information on whether it's discoverable could be obtained over IPMI). Unfortunately, those methods may ultimately not be available (support will vary from platform to platform), which means that we still need platform independent method triggered by userspace.

2022-02-09peci: Add device detectionIwona Winiarska5-1/+223
Since PECI devices are discoverable, we can dynamically detect devices that are actually available in the system. This change complements the earlier implementation by rescanning PECI bus to detect available devices. For this purpose, it also introduces the minimal API for PECI requests.

2022-02-09peci: Add core infrastructureIwona Winiarska6-0/+198
Intel processors provide access for various services designed to support processor and DRAM thermal management, platform manageability and processor interface tuning and diagnostics. Those services are available via the Platform Environment Control Interface (PECI) that provides a communication channel between the processor and the Baseboard Management Controller (BMC) or other platform management device. This change introduces PECI subsystem by adding the initial core module and API for controller drivers.

2022-02-08VMCI: dma dg: add support for DMA datagrams receiveJorgen Hansen1-24/+79
Use the DMA based receive operation instead of the ioread8_rep based datagram receive when DMA datagrams are supported. In the receive operation, configure the header to point to the page aligned VMCI_MAX_DG_SIZE part of the receive buffer using s/g configuration for the header. This ensures that the existing dispatch routine can be used with little modification. Initiate the receive by writing the lower 32 bit of the buffer to the VMCI_DATA_IN_LOW_ADDR register, and wait for the busy flag to be changed by the device using a wait queue. The existing dispatch routine for received datagrams is reused for the DMA datagrams with a few modifications: - the receive buffer is always the maximum size for DMA datagrams (IO ports would try with a shorter buffer first to reduce overhead of the ioread8_rep operation). - for DMA datagrams, datagrams are provided contiguous in the buffer as opposed to IO port datagrams, where they can start on any page boundary Reviewed-by: Vishnu Dasa <vdasa@vmware.com> Signed-off-by: Jorgen Hansen <jhansen@vmware.com> Link: https://lore.kernel.org/r/20220207102725.2742-9-jhansen@vmware.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2022-02-08VMCI: dma dg: add support for DMA datagrams sendsJorgen Hansen1-2/+43
Use DMA based send operation from the transmit buffer instead of the iowrite8_rep based datagram send when DMA datagrams are supported. The outgoing datagram is sent as inline data in the VMCI transmit buffer. Once the header has been configured, the send is initiated by writing the lower 32 bit of the buffer base address to the VMCI_DATA_OUT_LOW_ADDR register. Only then will the device process the header and the datagram itself. Following that, the driver busy waits (it isn't possible to sleep on the send path) for the header busy flag to change - indicating that the send is complete.

Detect the support for MMIO access through examination of the length of the region requested in BAR1. If it is 256KB, the VMCI device supports MMIO access to registers. If MMIO access is supported, map the area of the region used for MMIO access (64KB size at offset 128KB). Add wrapper functions for accessing 32 bit register accesses through either MMIO or IO ports based on device configuration. Sending and receiving datagrams through iowrite8_rep/ioread8_rep is left unchanged for now, and will be addressed in a later change.

2022-02-04fsi: Aspeed: Fix a potential double freeChristophe JAILLET1-6/+11
A struct device can never be devm_alloc()'ed. Here, it is embedded in "struct fsi_master", and "struct fsi_master" is embedded in "struct fsi_master_aspeed". Since "struct device" is embedded, the data structure embedding it must be released with the release function, as is already done here. So use kzalloc() instead of devm_kzalloc() when allocating "aspeed" and update all error handling branches accordingly. This prevent a potential double free(). This also fix another issue if opb_readl() fails. Instead of a direct return, it now jumps in the error handling path.

2022-02-04misc: open-dice: Add driver to expose DICE data to userspaceDavid Brazdil4-0/+222
Open Profile for DICE is an open protocol for measured boot compatible with the Trusted Computing Group's Device Identifier Composition Engine (DICE) specification. The generated Compound Device Identifier (CDI) certificates represent the hardware/software combination measured by DICE, and can be used for remote attestation and sealing. Add a driver that exposes reserved memory regions populated by firmware with DICE CDIs and exposes them to userspace via a character device. Userspace obtains the memory region's size from read() and calls mmap() to create a mapping of the memory region in its address space. The mapping is not allowed to be write+shared, giving userspace a guarantee that the data were not overwritten by another process. Userspace can also call write(), which triggers a wipe of the DICE data by the driver. Because both the kernel and userspace mappings use write-combine semantics, all clients observe the memory as zeroed after the syscall has returned.

2022-01-28dm: properly fix redundant bio-based IO accountingMike Snitzer1-2/+3
Record the start_time for a bio but defer the starting block core's IO accounting until after IO is submitted using bio_start_io_acct_time(). This approach avoids the need to mess around with any of the individual IO stats in response to a bio_split() that follows bio submission.

Reverts a1e1cb72d9649 ("dm: fix redundant IO accounting for bios that need splitting") because it was too narrow in scope (only addressed redundant 'sectors[]' accounting and not ios, nsecs[], etc).
