+ * HiSilicon erratum 161010801: This describes the limitation

+ * mappings for PCIe MSI transactions.
+ * PCIe controller on these platforms has to differentiate the
+ * MSI payload against other DMA payload and has to modify the
+ * MSI payload. This makes it difficult for these platforms to
+ * have a SMMU translation for MSI. In order to workaround this,
+ * ARM SMMUv3 driver requires a quirk to treat the MSI regions
+ * separately. Such a quirk is currently missing for DT based
+ * systems. Hence please make sure that the smmu pcie node on
+ * hip06 is disabled as this will break the PCIe functionality
+ * when iommu-map entry is used along with the PCIe node.

+ * HiSilicon erratum 161010801: This describes the limitation
+ * of HiSilicon platforms hip06/hip07 to support the SMMUv3
+ * mappings for PCIe MSI transactions.
+ * PCIe controller on these platforms has to differentiate the
+ * MSI payload against other DMA payload and has to modify the
+ * MSI payload. This makes it difficult for these platforms to
+ * have a SMMU translation for MSI. In order to workaround this,
+ * ARM SMMUv3 driver requires a quirk to treat the MSI regions
+ * separately. Such a quirk is currently missing for DT based
+ * systems. Hence please make sure that the smmu pcie node on
+ * hip07 is disabled as this will break the PCIe functionality
+ * when iommu-map entry is used along with the PCIe node.
+ * Refer:https://www.spinics.net/lists/arm-kernel/msg602812.html

+// Apple A7 1.97 10.5 (+33%) 6.73 (-1%(**))

+//
+// (*) Software SHA256 results are of lesser relevance, presented
+// mostly for informational purposes.
+// (**) The result is a trade-off: it's possible to improve it by
+// 10% (or by 1 cycle per round), but at the cost of 20% loss
+// on Cortex-A53 (or by 4 cycles per round).
+// (***) Super-impressive coefficients over gcc-generated code are
+// indication of some compiler "pathology", most notably code
+// generated with -mgeneral-regs-only is significanty faster
+// and the gap is only 40-90%.
+//
+// October 2016.
+//
+// Originally it was reckoned that it makes no sense to implement NEON
+// version of SHA256 for 64-bit processors. This is because performance
+// improvement on most wide-spread Cortex-A5x processors was observed
+// to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
+// observed that 32-bit NEON SHA256 performs significantly better than
+// 64-bit scalar version on *some* of the more recent processors. As
+// result 64-bit NEON version of SHA256 was added to provide best
+// all-round performance. For example it executes ~30% faster on X-Gene
+// and Mongoose. [For reference, NEON version of SHA512 is bound to
+// deliver much less improvement, likely *negative* on Cortex-A5x.
+// Which is why NEON support is limited to SHA256.]

+# SHA256/512 for ARMv8.
+#
+# Performance in cycles per processed byte and improvement coefficient
+# over code generated with "default" compiler:
+#
+# SHA256-hw SHA256(*) SHA512
+# Apple A7 1.97 10.5 (+33%) 6.73 (-1%(**))
+# Cortex-A53 2.38 15.5 (+115%) 10.0 (+150%(***))
+# Cortex-A57 2.31 11.6 (+86%) 7.51 (+260%(***))
+# Denver 2.01 10.5 (+26%) 6.70 (+8%)
+# X-Gene 20.0 (+100%) 12.8 (+300%(***))
+# Mongoose 2.36 13.0 (+50%) 8.36 (+33%)
+#
+# (*) Software SHA256 results are of lesser relevance, presented
+# mostly for informational purposes.
+# (**) The result is a trade-off: it's possible to improve it by
+# 10% (or by 1 cycle per round), but at the cost of 20% loss
+# on Cortex-A53 (or by 4 cycles per round).
+# (***) Super-impressive coefficients over gcc-generated code are
+# indication of some compiler "pathology", most notably code
+# generated with -mgeneral-regs-only is significanty faster
+# and the gap is only 40-90%.
+#
+# October 2016.
+#
+# Originally it was reckoned that it makes no sense to implement NEON
+# version of SHA256 for 64-bit processors. This is because performance
+# improvement on most wide-spread Cortex-A5x processors was observed
+# to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
+# observed that 32-bit NEON SHA256 performs significantly better than
+# 64-bit scalar version on *some* of the more recent processors. As
+# result 64-bit NEON version of SHA256 was added to provide best
+# all-round performance. For example it executes ~30% faster on X-Gene
+# and Mongoose. [For reference, NEON version of SHA512 is bound to
+# deliver much less improvement, likely *negative* on Cortex-A5x.
+# Which is why NEON support is limited to SHA256.]

+// SHA256/512 for ARMv8.
+//
+// Performance in cycles per processed byte and improvement coefficient
+// over code generated with "default" compiler:
+//
+// SHA256-hw SHA256(*) SHA512
+// Apple A7 1.97 10.5 (+33%) 6.73 (-1%(**))
+// Cortex-A53 2.38 15.5 (+115%) 10.0 (+150%(***))
+// Cortex-A57 2.31 11.6 (+86%) 7.51 (+260%(***))
+// Denver 2.01 10.5 (+26%) 6.70 (+8%)
+// X-Gene 20.0 (+100%) 12.8 (+300%(***))
+// Mongoose 2.36 13.0 (+50%) 8.36 (+33%)
+//
+// (*) Software SHA256 results are of lesser relevance, presented
+// mostly for informational purposes.
+// (**) The result is a trade-off: it's possible to improve it by
+// 10% (or by 1 cycle per round), but at the cost of 20% loss
+// on Cortex-A53 (or by 4 cycles per round).
+// (***) Super-impressive coefficients over gcc-generated code are
+// indication of some compiler "pathology", most notably code
+// generated with -mgeneral-regs-only is significanty faster
+// and the gap is only 40-90%.
+//
+// October 2016.
+//
+// Originally it was reckoned that it makes no sense to implement NEON
+// version of SHA256 for 64-bit processors. This is because performance
+// improvement on most wide-spread Cortex-A5x processors was observed
+// to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
+// observed that 32-bit NEON SHA256 performs significantly better than
+// 64-bit scalar version on *some* of the more recent processors. As
+// result 64-bit NEON version of SHA256 was added to provide best
+// all-round performance. For example it executes ~30% faster on X-Gene
+// and Mongoose. [For reference, NEON version of SHA512 is bound to
+// deliver much less improvement, likely *negative* on Cortex-A5x.
+// Which is why NEON support is limited to SHA256.]

+ * CPU capabilities:
+ *
+ * We use arm64_cpu_capabilities to represent system features, errata work
+ * arounds (both used internally by kernel and tracked in cpu_hwcaps) and
+ * ELF HWCAPs (which are exposed to user).
+ *
+ * To support systems with heterogeneous CPUs, we need to make sure that we
+ * detect the capabilities correctly on the system and take appropriate
+ * measures to ensure there are no incompatibilities.
+ *
+ * This comment tries to explain how we treat the capabilities.
+ * Each capability has the following list of attributes :
+ *
+ * 1) Scope of Detection : The system detects a given capability by
+ * performing some checks at runtime. This could be, e.g, checking the
+ * value of a field in CPU ID feature register or checking the cpu
+ * model. The capability provides a call back ( @matches() ) to
+ * perform the check. Scope defines how the checks should be performed.
+ * There are three cases:
+ *
+ * a) SCOPE_LOCAL_CPU: check all the CPUs and "detect" if at least one
+ * matches. This implies, we have to run the check on all the
+ * booting CPUs, until the system decides that state of the
+ * capability is finalised. (See section 2 below)
+ * Or
+ * b) SCOPE_SYSTEM: check all the CPUs and "detect" if all the CPUs
+ * matches. This implies, we run the check only once, when the
+ * system decides to finalise the state of the capability. If the
+ * capability relies on a field in one of the CPU ID feature
+ * registers, we use the sanitised value of the register from the
+ * CPU feature infrastructure to make the decision.
+ * Or
+ * c) SCOPE_BOOT_CPU: Check only on the primary boot CPU to detect the
+ * feature. This category is for features that are "finalised"
+ * (or used) by the kernel very early even before the SMP cpus
+ * are brought up.
+ *
+ * The process of detection is usually denoted by "update" capability
+ * state in the code.
+ *
+ * 2) Finalise the state : The kernel should finalise the state of a
+ * capability at some point during its execution and take necessary
+ * actions if any. Usually, this is done, after all the boot-time
+ * enabled CPUs are brought up by the kernel, so that it can make
+ * better decision based on the available set of CPUs. However, there
+ * are some special cases, where the action is taken during the early
+ * boot by the primary boot CPU. (e.g, running the kernel at EL2 with
+ * Virtualisation Host Extensions). The kernel usually disallows any
+ * changes to the state of a capability once it finalises the capability
+ * and takes any action, as it may be impossible to execute the actions
+ * safely. A CPU brought up after a capability is "finalised" is
+ * referred to as "Late CPU" w.r.t the capability. e.g, all secondary
+ * CPUs are treated "late CPUs" for capabilities determined by the boot
+ * CPU.
+ *
+ * At the moment there are two passes of finalising the capabilities.
+ * a) Boot CPU scope capabilities - Finalised by primary boot CPU via
+ * setup_boot_cpu_capabilities().
+ * b) Everything except (a) - Run via setup_system_capabilities().
+ *
+ * 3) Verification: When a CPU is brought online (e.g, by user or by the
+ * kernel), the kernel should make sure that it is safe to use the CPU,
+ * by verifying that the CPU is compliant with the state of the
+ * capabilities finalised already. This happens via :
+ *
+ * secondary_start_kernel()-> check_local_cpu_capabilities()
+ *
+ * As explained in (2) above, capabilities could be finalised at
+ * different points in the execution. Each newly booted CPU is verified
+ * against the capabilities that have been finalised by the time it
+ * boots.
+ *
+ * a) SCOPE_BOOT_CPU : All CPUs are verified against the capability
+ * except for the primary boot CPU.
+ *
+ * b) SCOPE_LOCAL_CPU, SCOPE_SYSTEM: All CPUs hotplugged on by the
+ * user after the kernel boot are verified against the capability.
+ *
+ * If there is a conflict, the kernel takes an action, based on the
+ * severity (e.g, a CPU could be prevented from booting or cause a
+ * kernel panic). The CPU is allowed to "affect" the state of the
+ * capability, if it has not been finalised already. See section 5
+ * for more details on conflicts.
+ *
+ * 4) Action: As mentioned in (2), the kernel can take an action for each
+ * detected capability, on all CPUs on the system. Appropriate actions
+ * include, turning on an architectural feature, modifying the control
+ * registers (e.g, SCTLR, TCR etc.) or patching the kernel via
+ * alternatives. The kernel patching is batched and performed at later
+ * point. The actions are always initiated only after the capability
+ * is finalised. This is usally denoted by "enabling" the capability.
+ * The actions are initiated as follows :
+ * a) Action is triggered on all online CPUs, after the capability is
+ * finalised, invoked within the stop_machine() context from
+ * enable_cpu_capabilitie().
+ *
+ * b) Any late CPU, brought up after (1), the action is triggered via:
+ *
+ * check_local_cpu_capabilities() -> verify_local_cpu_capabilities()
+ *
+ * 5) Conflicts: Based on the state of the capability on a late CPU vs.
+ * the system state, we could have the following combinations :
+ *
+ * x-----------------------------x
+ * | Type | System | Late CPU |
+ * |-----------------------------|
+ * | a | y | n |
+ * |-----------------------------|
+ * | b | n | y |
+ * x-----------------------------x
+ *
+ * Two separate flag bits are defined to indicate whether each kind of
+ * conflict can be allowed:
+ * ARM64_CPUCAP_OPTIONAL_FOR_LATE_CPU - Case(a) is allowed
+ * ARM64_CPUCAP_PERMITTED_FOR_LATE_CPU - Case(b) is allowed
+ *
+ * Case (a) is not permitted for a capability that the system requires
+ * all CPUs to have in order for the capability to be enabled. This is
+ * typical for capabilities that represent enhanced functionality.
+ *
+ * Case (b) is not permitted for a capability that must be enabled
+ * during boot if any CPU in the system requires it in order to run
+ * safely. This is typical for erratum work arounds that cannot be
+ * enabled after the corresponding capability is finalised.
+ *
+ * In some non-typical cases either both (a) and (b), or neither,
+ * should be permitted. This can be described by including neither
+ * or both flags in the capability's type field.

+ * protocol. In fact this statement is still present in ARM DDI 0487A.i.
+ *
+ * Unfortunately "is a 32-bit register" has a very special meaning for

+ * RES0.". RES0 is heavily used in the ARM architecture documents as a
+ * way to leave space for future architecture changes. So to translate a
+ * little for people who don't spend their spare time reading ARM architecture
+ * manuals, what "is a 32-bit register" actually means in this context is
+ * "is a 64-bit register but one with no meaning allocated to any of the
+ * upper 32-bits... *yet*".
+ *
+ * Perhaps then we should not be surprised that this has led to some
+ * confusion. Specifically a patch, influenced by the above translation,
+ * that extended PSTATE to 64-bit was accepted into gdb-7.7 but the patch
+ * was reverted in gdb-7.8.1 and all later releases, when this was
+ * discovered to be an undocumented protocol change.
+ *
+ * So... it is *not* wrong for us to only allocate 32-bits to PSTATE
+ * here even though the kernel itself allocates 64-bits for the same
+ * state. That is because this bit of code tells the kernel how the gdb
+ * remote protocol (well most versions of it) describes the register state.
+ *
+ * Note that if you are using one of the versions of gdb that supports
+ * the gdb-7.7 version of the protocol you cannot use kgdb directly
+ * without providing a custom register description (gdb can load new
+ * protocol descriptions at runtime).

+ * As ARMv8.0 only has the TTBR0_EL2 register, we cannot express
+ * "negative" addresses. This makes it impossible to directly share
+ * mappings with the kernel.
+ *
+ * Instead, give the HYP mode its own VA region at a fixed offset from
+ * the kernel by just masking the top bits (which are all ones for a
+ * kernel address). We need to find out how many bits to mask.
+ *
+ * We want to build a set of page tables that cover both parts of the
+ * idmap (the trampoline page used to initialize EL2), and our normal
+ * runtime VA space, at the same time.
+ *
+ * Given that the kernel uses VA_BITS for its entire address space,
+ * and that half of that space (VA_BITS - 1) is used for the linear
+ * mapping, we can also limit the EL2 space to (VA_BITS - 1).
+ *
+ * The main question is "Within the VA_BITS space, does EL2 use the
+ * top or the bottom half of that space to shadow the kernel's linear
+ * mapping?". As we need to idmap the trampoline page, this is
+ * determined by the range in which this page lives.
+ *
+ * If the page is in the bottom half, we have to use the top half. If
+ * the page is in the top half, we have to use the bottom half:
+ *
+ * T = __pa_symbol(__hyp_idmap_text_start)
+ * if (T & BIT(VA_BITS - 1))
+ * HYP_VA_MIN = 0 //idmap in upper half
+ * else
+ * HYP_VA_MIN = 1 << (VA_BITS - 1)
+ * HYP_VA_MAX = HYP_VA_MIN + (1 << (VA_BITS - 1)) - 1
+ *
+ * This of course assumes that the trampoline page exists within the
+ * VA_BITS range. If it doesn't, then it means we're in the odd case
+ * where the kernel idmap (as well as HYP) uses more levels than the
+ * kernel runtime page tables (as seen when the kernel is configured
+ * for 4k pages, 39bits VA, and yet memory lives just above that
+ * limit, forcing the idmap to use 4 levels of page tables while the
+ * kernel itself only uses 3). In this particular case, it doesn't
+ * matter which side of VA_BITS we use, as we're guaranteed not to
+ * conflict with anything.
+ *
+ * When using VHE, there are no separate hyp mappings and all KVM
+ * functionality is already mapped as part of the main kernel
+ * mappings, and none of this applies in that case.

+/*
+ * (Note: in this discussion, statements about FPSIMD apply equally to SVE.)
+ *
+ * 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 fpsimd_cpu field to thread_struct, which gets updated to
+ * the id of the current CPU every time 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_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.
+ *
+ * In order to allow softirq handlers to use FPSIMD, kernel_neon_begin() may
+ * save the task's FPSIMD context back to task_struct from softirq context.
+ * To prevent this from racing with the manipulation of the task's FPSIMD state
+ * from task context and thereby corrupting the state, it is necessary to
+ * protect any manipulation of a task's fpsimd_state or TIF_FOREIGN_FPSTATE
+ * flag with local_bh_disable() unless softirqs are already masked.
+ *
+ * For a certain task, the sequence may look something like this:
+ * - the task gets scheduled in; if both the task's fpsimd_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_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.
