+ * DSM software provided by Synology. Nonetheless, some earlier boards
+ * were delivered with an older version of u-boot that left internal
+ * registers mapped at 0xd0000000. If you have such a device you will
+ * not be able to directly boot a kernel based on this Device Tree. In
+ * that case, the preferred solution is to update your bootloader (e.g.
+ * by upgrading to latest version of DSM, or building a new one and
+ * installing it from u-boot prompt) or adjust the Devive Tree
+ * (s/0xf1000000/0xd0000000/ in 'ranges' below).

-/*
- * To avoid the complications of mimicing single-stepping on a
- * processor without a Next-PC or a single-step mode, and to
- * avoid having to deal with the side-effects of boosting, we
- * simulate or emulate (almost) all ARM instructions.
- *
- * "Simulation" is where the instruction's behavior is duplicated in
- * C code. "Emulation" is where the original instruction is rewritten
- * and executed, often by altering its registers.
- *
- * By having all behavior of the kprobe'd instruction completed before
- * returning from the kprobe_handler(), all locks (scheduler and
- * interrupt) can safely be released. There is no need for secondary
- * breakpoints, no race with MP or preemptable kernels, nor having to
- * clean up resources counts at a later time impacting overall system
- * performance. By rewriting the instruction, only the minimum registers
- * need to be loaded and saved back optimizing performance.
- *
- * Calling the insnslot_*_rwflags version of a function doesn't hurt
- * anything even when the CPSR flags aren't updated by the
- * instruction. It's just a little slower in return for saving
- * a little space by not having a duplicate function that doesn't
- * update the flags. (The same optimization can be said for
- * instructions that do or don't perform register writeback)
- * Also, instructions can either read the flags, only write the
- * flags, or read and write the flags. To save combinations
- * rather than for sheer performance, flag functions just assume
- * read and write of flags.

- * The following definitions and macros are used to build instruction
- * decoding tables for use by kprobe_decode_insn.
- *
- * These tables are a concatenation of entries each of which consist of one of
- * the decode_* structs. All of the fields in every type of decode structure
- * are of the union type decode_item, therefore the entire decode table can be
- * viewed as an array of these and declared like:
- *
- * static const union decode_item table_name[] = {};
- *
- * In order to construct each entry in the table, macros are used to
- * initialise a number of sequential decode_item values in a layout which
- * matches the relevant struct. E.g. DECODE_SIMULATE initialise a struct
- * decode_simulate by initialising four decode_item objects like this...
- *
- * {.bits = _type},
- * {.bits = _mask},
- * {.bits = _value},
- * {.handler = _handler},
- *
- * Initialising a specified member of the union means that the compiler
- * will produce a warning if the argument is of an incorrect type.
- *
- * Below is a list of each of the macros used to initialise entries and a
- * description of the action performed when that entry is matched to an
- * instruction. A match is found when (instruction & mask) == value.
- *
- * DECODE_TABLE(mask, value, table)
- * Instruction decoding jumps to parsing the new sub-table 'table'.
- *
- * DECODE_CUSTOM(mask, value, decoder)
- * The custom function 'decoder' is called to the complete decoding
- * of an instruction.
- *
- * DECODE_SIMULATE(mask, value, handler)
- * Set the probes instruction handler to 'handler', this will be used
- * to simulate the instruction when the probe is hit. Decoding returns
- * with INSN_GOOD_NO_SLOT.
- *
- * DECODE_EMULATE(mask, value, handler)
- * Set the probes instruction handler to 'handler', this will be used
- * to emulate the instruction when the probe is hit. The modified
- * instruction (see below) is placed in the probes instruction slot so it
- * may be called by the emulation code. Decoding returns with INSN_GOOD.
- *
- * DECODE_REJECT(mask, value)
- * Instruction decoding fails with INSN_REJECTED
- *
- * DECODE_OR(mask, value)
- * This allows the mask/value test of multiple table entries to be
- * logically ORed. Once an 'or' entry is matched the decoding action to
- * be performed is that of the next entry which isn't an 'or'. E.g.
- *
- * DECODE_OR (mask1, value1)
- * DECODE_OR (mask2, value2)
- * DECODE_SIMULATE (mask3, value3, simulation_handler)
- *
- * This means that if any of the three mask/value pairs match the
- * instruction being decoded, then 'simulation_handler' will be used
- * for it.
- *
- * Both the SIMULATE and EMULATE macros have a second form which take an
- * additional 'regs' argument.
- *
- * DECODE_SIMULATEX(mask, value, handler, regs)
- * DECODE_EMULATEX (mask, value, handler, regs)
- *
- * These are used to specify what kind of CPU register is encoded in each of the
- * least significant 5 nibbles of the instruction being decoded. The regs value
- * is specified using the REGS macro, this takes any of the REG_TYPE_* values
- * from enum decode_reg_type as arguments; only the '*' part of the name is
- * given. E.g.
- *
- * REGS(0, ANY, NOPC, 0, ANY)
- *
- * This indicates an instruction is encoded like:
- *
- * bits 19..16 ignore
- * bits 15..12 any register allowed here
- * bits 11.. 8 any register except PC allowed here
- * bits 7.. 4 ignore
- * bits 3.. 0 any register allowed here
- *
- * This register specification is checked after a decode table entry is found to
- * match an instruction (through the mask/value test). Any invalid register then
- * found in the instruction will cause decoding to fail with INSN_REJECTED. In
- * the above example this would happen if bits 11..8 of the instruction were
- * 1111, indicating R15 or PC.
- *
- * As well as checking for legal combinations of registers, this data is also
- * used to modify the registers encoded in the instructions so that an
- * emulation routines can use it. (See decode_regs() and INSN_NEW_BITS.)
- *
- * Here is a real example which matches ARM instructions of the form
- * "AND <Rd>,<Rn>,<Rm>,<shift> <Rs>"
- *
- * DECODE_EMULATEX (0x0e000090, 0x00000010, emulate_rd12rn16rm0rs8_rwflags,
- * REGS(ANY, ANY, NOPC, 0, ANY)),
- * ^ ^ ^ ^
- * Rn Rd Rs Rm
- *
- * Decoding the instruction "AND R4, R5, R6, ASL R15" will be rejected because

+ * To avoid the complications of mimicing single-stepping on a
+ * processor without a Next-PC or a single-step mode, and to
+ * avoid having to deal with the side-effects of boosting, we
+ * simulate or emulate (almost) all ARM instructions.
+ *
+ * "Simulation" is where the instruction's behavior is duplicated in
+ * C code. "Emulation" is where the original instruction is rewritten
+ * and executed, often by altering its registers.
+ *
+ * By having all behavior of the kprobe'd instruction completed before
+ * returning from the kprobe_handler(), all locks (scheduler and
+ * interrupt) can safely be released. There is no need for secondary
+ * breakpoints, no race with MP or preemptable kernels, nor having to
+ * clean up resources counts at a later time impacting overall system
+ * performance. By rewriting the instruction, only the minimum registers
+ * need to be loaded and saved back optimizing performance.
+ *
+ * Calling the insnslot_*_rwflags version of a function doesn't hurt
+ * anything even when the CPSR flags aren't updated by the
+ * instruction. It's just a little slower in return for saving
+ * a little space by not having a duplicate function that doesn't
+ * update the flags. (The same optimization can be said for
+ * instructions that do or don't perform register writeback)
+ * Also, instructions can either read the flags, only write the
+ * flags, or read and write the flags. To save combinations
+ * rather than for sheer performance, flag functions just assume
+ * read and write of flags.

+ * The following definitions and macros are used to build instruction
+ * decoding tables for use by probes_decode_insn.
+ *
+ * These tables are a concatenation of entries each of which consist of one of
+ * the decode_* structs. All of the fields in every type of decode structure
+ * are of the union type decode_item, therefore the entire decode table can be
+ * viewed as an array of these and declared like:
+ *
+ * static const union decode_item table_name[] = {};
+ *
+ * In order to construct each entry in the table, macros are used to
+ * initialise a number of sequential decode_item values in a layout which
+ * matches the relevant struct. E.g. DECODE_SIMULATE initialise a struct
+ * decode_simulate by initialising four decode_item objects like this...
+ *
+ * {.bits = _type},
+ * {.bits = _mask},
+ * {.bits = _value},
+ * {.action = _handler},
+ *
+ * Initialising a specified member of the union means that the compiler
+ * will produce a warning if the argument is of an incorrect type.
+ *
+ * Below is a list of each of the macros used to initialise entries and a
+ * description of the action performed when that entry is matched to an
+ * instruction. A match is found when (instruction & mask) == value.
+ *
+ * DECODE_TABLE(mask, value, table)
+ * Instruction decoding jumps to parsing the new sub-table 'table'.
+ *
+ * DECODE_CUSTOM(mask, value, decoder)
+ * The value of 'decoder' is used as an index into the array of
+ * action functions, and the retrieved decoder function is invoked
+ * to complete decoding of the instruction.
+ *
+ * DECODE_SIMULATE(mask, value, handler)
+ * The probes instruction handler is set to the value found by
+ * indexing into the action array using the value of 'handler'. This
+ * will be used to simulate the instruction when the probe is hit.
+ * Decoding returns with INSN_GOOD_NO_SLOT.
+ *
+ * DECODE_EMULATE(mask, value, handler)
+ * The probes instruction handler is set to the value found by
+ * indexing into the action array using the value of 'handler'. This
+ * will be used to emulate the instruction when the probe is hit. The
+ * modified instruction (see below) is placed in the probes instruction
+ * slot so it may be called by the emulation code. Decoding returns
+ * with INSN_GOOD.
+ *
+ * DECODE_REJECT(mask, value)
+ * Instruction decoding fails with INSN_REJECTED
+ *
+ * DECODE_OR(mask, value)
+ * This allows the mask/value test of multiple table entries to be
+ * logically ORed. Once an 'or' entry is matched the decoding action to
+ * be performed is that of the next entry which isn't an 'or'. E.g.
+ *
+ * DECODE_OR (mask1, value1)
+ * DECODE_OR (mask2, value2)
+ * DECODE_SIMULATE (mask3, value3, simulation_handler)
+ *
+ * This means that if any of the three mask/value pairs match the
+ * instruction being decoded, then 'simulation_handler' will be used
+ * for it.
+ *
+ * Both the SIMULATE and EMULATE macros have a second form which take an
+ * additional 'regs' argument.
+ *
+ * DECODE_SIMULATEX(mask, value, handler, regs)
+ * DECODE_EMULATEX (mask, value, handler, regs)
+ *
+ * These are used to specify what kind of CPU register is encoded in each of the
+ * least significant 5 nibbles of the instruction being decoded. The regs value
+ * is specified using the REGS macro, this takes any of the REG_TYPE_* values
+ * from enum decode_reg_type as arguments; only the '*' part of the name is
+ * given. E.g.
+ *
+ * REGS(0, ANY, NOPC, 0, ANY)
+ *
+ * This indicates an instruction is encoded like:
+ *
+ * bits 19..16 ignore
+ * bits 15..12 any register allowed here
+ * bits 11.. 8 any register except PC allowed here
+ * bits 7.. 4 ignore
+ * bits 3.. 0 any register allowed here
+ *
+ * This register specification is checked after a decode table entry is found to
+ * match an instruction (through the mask/value test). Any invalid register then
+ * found in the instruction will cause decoding to fail with INSN_REJECTED. In
+ * the above example this would happen if bits 11..8 of the instruction were
+ * 1111, indicating R15 or PC.
+ *
+ * As well as checking for legal combinations of registers, this data is also
+ * used to modify the registers encoded in the instructions so that an
+ * emulation routines can use it. (See decode_regs() and INSN_NEW_BITS.)
+ *
+ * Here is a real example which matches ARM instructions of the form
+ * "AND <Rd>,<Rn>,<Rm>,<shift> <Rs>"
+ *
+ * DECODE_EMULATEX (0x0e000090, 0x00000010, PROBES_DATA_PROCESSING_REG,
+ * REGS(ANY, ANY, NOPC, 0, ANY)),
+ * ^ ^ ^ ^
+ * Rn Rd Rs Rm
+ *
+ * Decoding the instruction "AND R4, R5, R6, ASL R15" will be rejected because
+ * Rs == R15
+ *
+ * Decoding the instruction "AND R4, R5, R6, ASL R7" will be accepted and the
+ * instruction will be modified to "AND R0, R2, R3, ASL R1" and then placed into
+ * the kprobes instruction slot. This can then be called later by the handler
+ * function emulate_rd12rn16rm0rs8_rwflags (a pointer to which is retrieved from
+ * the indicated slot in the action array), in order to simulate the instruction.

- * TNETV107X platforms do not use the static mappings from Davinci

- *
- * The primary impact of the current model is that IO_ADDRESS() is not to be
- * used to map registers on TNETV107X.
- *
- * 1. The first chunk is for INTC: This needs to be mapped in via iotable
- * because ioremap() does not seem to be operational at the time when
- * irqs are initialized. Without this, consistent dma init bombs.
- *
- * 2. The second chunk maps in register areas that need to be populated into

+ help
+ The PL310 L2 cache controller implements three types of Clean &
+ Invalidate maintenance operations: by Physical Address
+ (offset 0x7F0), by Index/Way (0x7F8) and by Way (0x7FC).
+ They are architecturally defined to behave as the execution of a
+ clean operation followed immediately by an invalidate operation,
+ both performing to the same memory location. This functionality
+ is not correctly implemented in PL310 prior to r2p0 (fixed in r2p0)
+ as clean lines are not invalidated as a result of these operations.
+
+config PL310_ERRATA_727915
+ bool "PL310 errata: Background Clean & Invalidate by Way operation can cause data corruption"
+ help
+ PL310 implements the Clean & Invalidate by Way L2 cache maintenance
+ operation (offset 0x7FC). This operation runs in background so that
+ PL310 can handle normal accesses while it is in progress. Under very
+ rare circumstances, due to this erratum, write data can be lost when
+ PL310 treats a cacheable write transaction during a Clean &
+ Invalidate by Way operation. Revisions prior to r3p1 are affected by
+ this errata (fixed in r3p1).
+
+config PL310_ERRATA_753970
+ bool "PL310 errata: cache sync operation may be faulty"
+ help
+ This option enables the workaround for the 753970 PL310 (r3p0) erratum.
+
+ Under some condition the effect of cache sync operation on
+ the store buffer still remains when the operation completes.
+ This means that the store buffer is always asked to drain and
+ this prevents it from merging any further writes. The workaround
+ is to replace the normal offset of cache sync operation (0x730)
+ by another offset targeting an unmapped PL310 register 0x740.
+ This has the same effect as the cache sync operation: store buffer
+ drain and waiting for all buffers empty.
+
+config PL310_ERRATA_769419
+ bool "PL310 errata: no automatic Store Buffer drain"
+ help
+ On revisions of the PL310 prior to r3p2, the Store Buffer does
+ not automatically drain. This can cause normal, non-cacheable
+ writes to be retained when the memory system is idle, leading
+ to suboptimal I/O performance for drivers using coherent DMA.
+ This option adds a write barrier to the cpu_idle loop so that,
+ on systems with an outer cache, the store buffer is drained
+ explicitly.

+ ARMv8 obsoletes the use of A32 SWP/SWPB instructions such that
+ they are always undefined. Say Y here to enable software
+ emulation of these instructions for userspace using LDXR/STXR.
+
+ In some older versions of glibc [<=2.8] SWP is used during futex
+ trylock() operations with the assumption that the code will not
+ be preempted. This invalid assumption may be more likely to fail
+ with SWP emulation enabled, leading to deadlock of the user
+ application.
+
+ NOTE: when accessing uncached shared regions, LDXR/STXR rely
+ on an external transaction monitoring block called a global
+ monitor to maintain update atomicity. If your system does not
+ implement a global monitor, this option can cause programs that
+ perform SWP operations to uncached memory to deadlock.

+ instructions instead.
+
+ Say Y here to enable software emulation of these

+ * In order to reduce the number of times the FPSIMD state is needlessly saved
+ * and restored, we need to keep track of two things:
+ * (a) for each task, we need to remember which CPU was the last one to have
+ * the task's FPSIMD state loaded into its FPSIMD registers;
+ * (b) for each CPU, we need to remember which task's userland FPSIMD state has
+ * been loaded into its FPSIMD registers most recently, or whether it has
+ * been used to perform kernel mode NEON in the meantime.
+ *
+ * For (a), we add a 'cpu' field to struct fpsimd_state, which gets updated to
+ * the id of the current CPU everytime the state is loaded onto a CPU. For (b),
+ * we add the per-cpu variable 'fpsimd_last_state' (below), which contains the
+ * address of the userland FPSIMD state of the task that was loaded onto the CPU
+ * the most recently, or NULL if kernel mode NEON has been performed after that.
+ *
+ * With this in place, we no longer have to restore the next FPSIMD state right
+ * when switching between tasks. Instead, we can defer this check to userland
+ * resume, at which time we verify whether the CPU's fpsimd_last_state and the
+ * task's fpsimd_state.cpu are still mutually in sync. If this is the case, we
+ * can omit the FPSIMD restore.
+ *
+ * As an optimization, we use the thread_info flag TIF_FOREIGN_FPSTATE to
+ * indicate whether or not the userland FPSIMD state of the current task is
+ * present in the registers. The flag is set unless the FPSIMD registers of this
+ * CPU currently contain the most recent userland FPSIMD state of the current
+ * task.
+ *
+ * For a certain task, the sequence may look something like this:
+ * - the task gets scheduled in; if both the task's fpsimd_state.cpu field
+ * contains the id of the current CPU, and the CPU's fpsimd_last_state per-cpu
+ * variable points to the task's fpsimd_state, the TIF_FOREIGN_FPSTATE flag is
+ * cleared, otherwise it is set;
+ *
+ * - the task returns to userland; if TIF_FOREIGN_FPSTATE is set, the task's
+ * userland FPSIMD state is copied from memory to the registers, the task's
+ * fpsimd_state.cpu field is set to the id of the current CPU, the current
+ * CPU's fpsimd_last_state pointer is set to this task's fpsimd_state and the
+ * TIF_FOREIGN_FPSTATE flag is cleared;
+ *
+ * - the task executes an ordinary syscall; upon return to userland, the
+ * TIF_FOREIGN_FPSTATE flag will still be cleared, so no FPSIMD state is
+ * restored;
+ *
+ * - the task executes a syscall which executes some NEON instructions; this is
+ * preceded by a call to kernel_neon_begin(), which copies the task's FPSIMD
+ * register contents to memory, clears the fpsimd_last_state per-cpu variable
+ * and sets the TIF_FOREIGN_FPSTATE flag;
+ *
+ * - the task gets preempted after kernel_neon_end() is called; as we have not
+ * returned from the 2nd syscall yet, TIF_FOREIGN_FPSTATE is still set so
+ * whatever is in the FPSIMD registers is not saved to memory, but discarded.

+ *
+ * We have:
+ * - Root source, usually 12MHz supplied by an external crystal
+ * - 3 PLLs which generate multiples of root rate [AUX, CPU, AUX2]
+ *
+ * Dividers:
+ * - 6 clock dividers with:
+ * * selectable source [one of the PLLs],
+ * * output divided between [2 .. 512 in steps of 2] (!Au1300)
+ * or [1 .. 256 in steps of 1] (Au1300),
+ * * can be enabled individually.
+ *
+ * - up to 6 "internal" (fixed) consumers which:
+ * * take either AUXPLL or one of the above 6 dividers as input,
+ * * divide this input by 1, 2, or 4 (and 3 on Au1300).
+ * * can be disabled separately.
+ *
+ * Misc clocks:
+ * - sysbus clock: CPU core clock (CPUPLL) divided by 2, 3 or 4.
+ * depends on board design and should be set by bootloader, read-only.
+ * - peripheral clock: half the rate of sysbus clock, source for a lot
+ * of peripheral blocks, read-only.
+ * - memory clock: clk rate to main memory chips, depends on board
+ * design and is read-only,
+ * - lrclk: the static bus clock signal for synchronous operation.
+ * depends on board design, must be set by bootloader,
+ * but may be required to correctly configure devices attached to
+ * the static bus. The Au1000/1500/1100 manuals call it LCLK, on
+ * later models it's called RCLK.

- * current->brk to pick up all of the user variables, plus any memory
- * that may have been sbrk'ed. No attempt is made to determine if a
- * page is demand-zero or if a page is totally unused, we just cover

- * Variant clock event timer support for SMTC on MIPS 34K, 1004K
- * or other MIPS MT cores.
- *
- * Notes on SMTC Support:
- *
- * SMTC has multiple microthread TCs pretending to be Linux CPUs.
- * But there's only one Count/Compare pair per VPE, and Compare
- * interrupts are taken opportunisitically by available TCs
- * bound to the VPE with the Count register. The new timer
- * framework provides for global broadcasts, but we really
- * want VPE-level multicasts for best behavior. So instead
- * of invoking the high-level clock-event broadcast code,
- * this version of SMTC support uses the historical SMTC
- * multicast mechanisms "under the hood", appearing to the
- * generic clock layer as if the interrupts are per-CPU.
- *
- * The approach taken here is to maintain a set of NR_CPUS
- * virtual timers, and track which "CPU" needs to be alerted
- * at each event.
- *
- * It's unlikely that we'll see a MIPS MT core with more than
- * 2 VPEs, but we *know* that we won't need to handle more
- * VPEs than we have "CPUs". So NCPUs arrays of NCPUs elements
- * is always going to be overkill, but always going to be enough.

- * roughly once every four billion events, which at 1000 HZ means
- * about once every 50 days. If that's actually a problem, one

+ /* INSTRUCTION EMULATION
+ * ---------------------
+ *
+ * Nios II processors generate exceptions for unimplemented instructions.
+ * The routines below emulate these instructions. Depending on the
+ * processor core, the only instructions that might need to be emulated
+ * are div, divu, mul, muli, mulxss, mulxsu, and mulxuu.
+ *
+ * The emulations match the instructions, except for the following
+ * limitations:
+ *
+ * 1) The emulation routines do not emulate the use of the exception
+ * temporary register (et) as a source operand because the exception
+ * handler already has modified it.
+ *
+ * 2) The routines do not emulate the use of the stack pointer (sp) or
+ * the exception return address register (ea) as a destination because
+ * modifying these registers crashes the exception handler or the
+ * interrupted routine.
+ *
+ * Detailed Design
+ * ---------------
+ *
+ * The emulation routines expect the contents of integer registers r0-r31
+ * to be on the stack at addresses sp, 4(sp), 8(sp), ... 124(sp). The
+ * routines retrieve source operands from the stack and modify the
+ * destination register's value on the stack prior to the end of the
+ * exception handler. Then all registers except the destination register
+ * are restored to their previous values.
+ *
+ * The instruction that causes the exception is found at address -4(ea).
+ * The instruction's OP and OPX fields identify the operation to be
+ * performed.
+ *
+ * One instruction, muli, is an I-type instruction that is identified by
+ * an OP field of 0x24.
+ *
+ * muli AAAAA,BBBBB,IIIIIIIIIIIIIIII,-0x24-
+ * 27 22 6 0 <-- LSB of field
+ *
+ * The remaining emulated instructions are R-type and have an OP field
+ * of 0x3a. Their OPX fields identify them.
+ *
+ * R-type AAAAA,BBBBB,CCCCC,XXXXXX,NNNNN,-0x3a-
+ * 27 22 17 11 6 0 <-- LSB of field
+ *
+ *
+ * Opcode Encoding. muli is identified by its OP value. Then OPX & 0x02
+ * is used to differentiate between the division opcodes and the
+ * remaining multiplication opcodes.
+ *
+ * Instruction OP OPX OPX & 0x02
+ * ----------- ---- ---- ----------
+ * muli 0x24
+ * divu 0x3a 0x24 0

+ * - x = domains
+ * - y = indexes in the domain (core, chip, vcpu, node, etc)
+ * - z = offset into the counter space
+ * - w = lpars (guest vms, "logical partitions")
+ * - A single request is: x,y,y_last,z,z_last,w,w_last
+ * - this means we can retrieve a rectangle of counters in y,z for a single x.
+ *
+ * - Things to consider (ignoring w):
+ * - input cost_per_request = 16
+ * - output cost_per_result(ys,zs) = 8 + 8 * ys + ys * zs
+ * - limited number of requests per hcall (must fit into 4K bytes)
+ * - 4k = 16 [buffer header] - 16 [request size] * request_count

+ * So a BE kernel will have the leftmost of the above in the MSB
+ * and rightmost in the LSB and can just then "cast" the u32 "data"
+ * down to the appropriate quantity and write it.
+ *
+ * However, an LE kernel can't. It doesn't need to swap because a
+ * load from data followed by a store to user are going to preserve

+/*
+ * Split/unsplit procedure:
+ *
+ * A core can be in one of three states, unsplit, 2-way split, and 4-way split.
+ *
+ * The mapping to subcores_per_core is simple:
+ *
+ * State | subcores_per_core
+ * ------------|------------------
+ * Unsplit | 1
+ * 2-way split | 2
+ * 4-way split | 4
+ *
+ * The core is split along thread boundaries, the mapping between subcores and
+ * threads is as follows:
+ *
+ * Unsplit:
+ * ----------------------------
+ * Subcore | 0 |
+ * ----------------------------
+ * Thread | 0 1 2 3 4 5 6 7 |
+ * ----------------------------
+ *
+ * 2-way split:
+ * -------------------------------------
+ * Subcore | 0 | 1 |
+ * -------------------------------------
+ * Thread | 0 1 2 3 | 4 5 6 7 |
+ * -------------------------------------
+ *
+ * 4-way split:
+ * -----------------------------------------
+ * Subcore | 0 | 1 | 2 | 3 |
+ * -----------------------------------------
+ * Thread | 0 1 | 2 3 | 4 5 | 6 7 |
+ * -----------------------------------------
+ *
+ *
+ * Transitions
+ * -----------
+ *
+ * It is not possible to transition between either of the split states, the
+ * core must first be unsplit. The legal transitions are:
+ *
+ * ----------- ---------------
+ * | | <----> | 2-way split |
+ * | | ---------------
+ * | Unsplit |
+ * | | ---------------
+ * | | <----> | 4-way split |
+ * ----------- ---------------
+ *
+ * Unsplitting
+ * -----------
+ *
+ * Unsplitting is the simpler procedure. It requires thread 0 to request the
+ * unsplit while all other threads NAP.
+ *
+ * Thread 0 clears HID0_POWER8_DYNLPARDIS (Dynamic LPAR Disable). This tells
+ * the hardware that if all threads except 0 are napping, the hardware should
+ * unsplit the core.
+ *
+ * Non-zero threads are sent to a NAP loop, they don't exit the loop until they
+ * see the core unsplit.
+ *
+ * Core 0 spins waiting for the hardware to see all the other threads napping
+ * and perform the unsplit.
+ *
+ * Once thread 0 sees the unsplit, it IPIs the secondary threads to wake them
+ * out of NAP. They will then see the core unsplit and exit the NAP loop.
+ *
+ * Splitting
+ * ---------
+ *
+ * The basic splitting procedure is fairly straight forward. However it is
+ * complicated by the fact that after the split occurs, the newly created
+ * subcores are not in a fully initialised state.
+ *
+ * Most notably the subcores do not have the correct value for SDR1, which
+ * means they must not be running in virtual mode when the split occurs. The
+ * subcores have separate timebases SPRs but these are pre-synchronised by
+ * opal.
+ *
+ * To begin with secondary threads are sent to an assembly routine. There they
+ * switch to real mode, so they are immune to the uninitialised SDR1 value.
+ * Once in real mode they indicate that they are in real mode, and spin waiting
+ * to see the core split.
+ *
+ * Thread 0 waits to see that all secondaries are in real mode, and then begins
+ * the splitting procedure. It firstly sets HID0_POWER8_DYNLPARDIS, which
+ * prevents the hardware from unsplitting. Then it sets the appropriate HID bit
+ * to request the split, and spins waiting to see that the split has happened.
+ *
+ * Concurrently the secondaries will notice the split. When they do they set up
+ * their SPRs, notably SDR1, and then they can return to virtual mode and exit
+ * the procedure.

+ * This function is supposed to be used after regular guest access functions

+ *
+ * rc = write_guest(vcpu, addr, data, len);
+ * if (rc)
+ * return kvm_s390_inject_prog_cond(vcpu, rc);
+ *
+ * A negative return code from guest access functions implies an internal error
+ * like e.g. out of memory. In these cases no program check should be injected
+ * to the guest.
+ * A positive value implies that an exception happened while accessing a guest's
+ * memory. In this case all data belonging to the corresponding program check
+ * has been stored in vcpu->arch.pgm and can be injected with
+ * kvm_s390_inject_prog_irq().
+ *
+ * Returns: - the original @rc value if @rc was negative (internal error)
+ * - zero if @rc was already zero
+ * - zero or error code from injecting if @rc was positive
+ * (program check injected to @vcpu)

+ * version 1.0 interrupt APIs numbered 0xa0 to 0xa6 will result in the
+ * ENOTSUPPORTED error being returned.
+ *
+ * with an emphasis on "all interrupt sources".
+ *
+ * To correct this, major version 3.0 was created which does actually

+ *
+ * This work was inspired by the AES CTR mode optimization published
+ * in Intel Optimized IPSEC Cryptograhpic library.

+# STRUCT job_aes2
+# RES_Q .plaintext, 1
+# RES_Q .ciphertext, 1
+# RES_DQ .IV, 1
+# RES_B .nested, _JOB_AES_SIZE, _JOB_AES_ALIGN

+# size2, align2, \
+# ...
+# ENDSTRUCT
+# # Following only needed if nesting
+# %assign job_aes2_size _FIELD_OFFSET
+# %assign job_aes2_align _STRUCT_ALIGN
+#
+# RES_* macros take a name, a count and an optional alignment.
+# The count in in terms of the base size of the macro, and the
+# default alignment is the base size.
+# The macros are:
+# Macro Base size
+# RES_B 1
+# RES_W 2
+# RES_D 4
+# RES_Q 8
+# RES_DQ 16
+# RES_Y 32
+# RES_Z 64
+#
+# RES_U defines a union. It's arguments are a name and two or more
+# pairs of "size, alignment"
+#
+# The two assigns are only needed if this structure is being nested
+# within another. Even if the assigns are not done, one can still use
+# STRUCT_NAME_size as the size of the structure.
+#
+# Note that for nesting, you still need to assign to STRUCT_NAME_size.
+#
+# The differences between this and using "struc" directly are that each
+# type is implicitly aligned to its natural length (although this can be
+# over-ridden with an explicit third parameter), and that the structure
+# is padded at the end to its overall alignment.

+ * Example where none of bx,cx,dx can be used as scratch reg:
+ * c4 e2 63 f6 0d disp32 mulx disp32(%rip),%ebx,%ecx
+ * [v]pcmpistri: implicitly uses cx, xmm0

+ * Currently, we have two sorts of write-protection, a) the first one

+ * used to sync dirty bitmap when we do KVM_GET_DIRTY_LOG. The differences
+ * between these two sorts are:
+ * 1) the first case clears SPTE_MMU_WRITEABLE bit.
+ * 2) the first case requires flushing tlb immediately avoiding corrupting
+ * shadow page table between all vcpus so it should be in the protection of
+ * mmu-lock. And the another case does not need to flush tlb until returning
+ * the dirty bitmap to userspace since it only write-protects the page
+ * logged in the bitmap, that means the page in the dirty bitmap is not
+ * missed, so it can flush tlb out of mmu-lock.
+ *
+ * So, there is the problem: the first case can meet the corrupted tlb caused
+ * by another case which write-protects pages but without flush tlb
+ * immediately. In order to making the first case be aware this problem we let
+ * it flush tlb if we try to write-protect a spte whose SPTE_MMU_WRITEABLE bit
+ * is set, it works since another case never touches SPTE_MMU_WRITEABLE bit.
+ *
+ * Anyway, whenever a spte is updated (only permission and status bits are
+ * changed) we need to check whether the spte with SPTE_MMU_WRITEABLE becomes
+ * readonly, if that happens, we need to flush tlb. Fortunately,
+ * mmu_spte_update() has already handled it perfectly.
+ *
+ * The rules to use SPTE_MMU_WRITEABLE and PT_WRITABLE_MASK:
+ * - if we want to see if it has writable tlb entry or if the spte can be
+ * writable on the mmu mapping, check SPTE_MMU_WRITEABLE, this is the most
+ * case, otherwise
+ * - if we fix page fault on the spte or do write-protection by dirty logging,
+ * check PT_WRITABLE_MASK.
+ *

+ * vdso2c - A vdso image preparation tool
+ * Copyright (c) 2014 Andy Lutomirski and others
+ * Licensed under the GPL v2
+ *
+ * vdso2c requires stripped and unstripped input. It would be trivial
+ * to fully strip the input in here, but, for reasons described below,
+ * we need to write a section table. Doing this is more or less
+ * equivalent to dropping all non-allocatable sections, but it's
+ * easier to let objcopy handle that instead of doing it ourselves.
+ * If we ever need to do something fancier than what objcopy provides,
+ * it would be straightforward to add here.
+ *
+ * We're keep a section table for a few reasons:
+ *
+ * The Go runtime had a couple of bugs: it would read the section
+ * table to try to figure out how many dynamic symbols there were (it
+ * shouldn't have looked at the section table at all) and, if there
+ * were no SHT_SYNDYM section table entry, it would use an
+ * uninitialized value for the number of symbols. An empty DYNSYM
+ * table would work, but I see no reason not to write a valid one (and
+ * keep full performance for old Go programs). This hack is only
+ * needed on x86_64.
+ *
+ * The bug was introduced on 2012-08-31 by:
+ * https://code.google.com/p/go/source/detail?r=56ea40aac72b
+ * and was fixed on 2014-06-13 by:
+ * https://code.google.com/p/go/source/detail?r=fc1cd5e12595
+ *
+ * Binutils has issues debugging the vDSO: it reads the section table to
+ * find SHT_NOTE; it won't look at PT_NOTE for the in-memory vDSO, which
+ * would break build-id if we removed the section table. Binutils
+ * also requires that shstrndx != 0. See:
+ * https://sourceware.org/bugzilla/show_bug.cgi?id=17064
+ *
+ * elfutils might not look for PT_NOTE if there is a section table at
+ * all. I don't know whether this matters for any practical purpose.
+ *
+ * For simplicity, rather than hacking up a partial section table, we
+ * just write a mostly complete one. We omit non-dynamic symbols,
+ * though, since they're rather large.
+ *
+ * Once binutils gets fixed, we might be able to drop this for all but
+ * the 64-bit vdso, since build-id only works in kernel RPMs, and
+ * systems that update to new enough kernel RPMs will likely update
+ * binutils in sync. build-id has never worked for home-built kernel
+ * RPMs without manual symlinking, and I suspect that no one ever does
+ * that.
