      platform/x86: Add PMC Driver for Intel Core SoC · b740d2e9
      Rajneesh Bhardwaj 提交于
      This patch adds the Power Management Controller driver as a PCI driver
      for Intel Core SoC architecture.
      
      This driver can utilize debugging capabilities and supported features
      as exposed by the Power Management Controller.
      
      Please refer to the below specification for more details on PMC features.
      http://www.intel.in/content/www/in/en/chipsets/100-series-chipset-datasheet-vol-2.html
      
      The current version of this driver exposes SLP_S0_RESIDENCY counter.
      This counter can be used for detecting fragile SLP_S0 signal related
      failures and take corrective actions when PCH SLP_S0 signal is not
      asserted after kernel freeze as part of suspend to idle flow
      (echo freeze > /sys/power/state).
      
      Intel Platform Controller Hub (PCH) asserts SLP_S0 signal when it
      detects favorable conditions to enter its low power mode. As a
      pre-requisite the SoC should be in deepest possible Package C-State
      and devices should be in low power mode. For example, on Skylake SoC
      the deepest Package C-State is Package C10 or PC10. Suspend to idle
      flow generally leads to PC10 state but PC10 state may not be sufficient
      for realizing the platform wide power potential which SLP_S0 signal
      assertion can provide.
      
      SLP_S0 signal is often connected to the Embedded Controller (EC) and the
      Power Management IC (PMIC) for other platform power management related
      optimizations.
      
      In general, SLP_S0 assertion == PC10 + PCH low power mode + ModPhy Lanes
      power gated + PLL Idle.
      
      As part of this driver, a mechanism to read the SLP_S0_RESIDENCY is exposed
      as an API and also debugfs features are added to indicate SLP_S0 signal
      assertion residency in microseconds.

      x86: remove more uaccess_32.h complexity · bd28b145
      Linus Torvalds 提交于
      I'm looking at trying to possibly merge the 32-bit and 64-bit versions
      of the x86 uaccess.h implementation, but first this needs to be cleaned
      up.
      
      For example, the 32-bit version of "__copy_from_user_inatomic()" is
      mostly the special cases for the constant size, and it's actually almost
      never relevant.  Most users aren't actually using a constant size
      anyway, and the few cases that do small constant copies are better off
      just using __get_user() instead.
      
      So get rid of the unnecessary complexity.

      x86/mm/mpx: Work around MPX erratum SKD046 · 0f6ff2bc
      Dave Hansen 提交于
      This erratum essentially causes the CPU to forget which privilege
      level it is operating on (kernel vs. user) for the purposes of MPX.
      
      This erratum can only be triggered when a system is not using
      Supervisor Mode Execution Prevention (SMEP).  Our workaround for
      the erratum is to ensure that MPX can only be used in cases where
      SMEP is present in the processor and is enabled.
      
      This erratum only affects Core processors.  Atom is unaffected.
      But, there is no architectural way to determine Atom vs. Core.
      So, we just apply this workaround to all processors.  It's
      possible that it will mistakenly disable MPX on some Atom
      processsors or future unaffected Core processors.  There are
      currently no processors that have MPX and not SMEP.  It would
      take something akin to a hypervisor masking SMEP out on an Atom
      processor for this to present itself on current hardware.
      
      More details can be found at:

        SKD046 Branch Instructions May Initialize MPX Bound Registers Incorrectly
      
        Problem:
      
        Depending on the current Intel MPX (Memory Protection
        Extensions) configuration, execution of certain branch
        instructions (near CALL, near RET, near JMP, and Jcc
        instructions) without a BND prefix (F2H) initialize the MPX bound
        registers. Due to this erratum, such a branch instruction that is
        executed both with CPL = 3 and with CPL < 3 may not use the
        correct MPX configuration register (BNDCFGU or BNDCFGS,
        respectively) for determining whether to initialize the bound
        registers; it may thus initialize the bound registers when it
        should not, or fail to initialize them when it should.
      
        Implication:
      
        A branch instruction that has executed both in user mode and in
        supervisor mode (from the same linear address) may cause a #BR
        (bound range fault) when it should not have or may not cause a
        #BR when it should have.  Workaround An operating system can
        avoid this erratum by setting CR4.SMEP[bit 20] to enable
        supervisor-mode execution prevention (SMEP). When SMEP is
        enabled, no code can be executed both with CPL = 3 and with CPL < 3.

      arch: fix has_transparent_hugepage() · fd8cfd30
      Hugh Dickins 提交于
      I've just discovered that the useful-sounding has_transparent_hugepage()
      is actually an architecture-dependent minefield: on some arches it only
      builds if CONFIG_TRANSPARENT_HUGEPAGE=y, on others it's also there when
      not, but on some of those (arm and arm64) it then gives the wrong
      answer; and on mips alone it's marked __init, which would crash if
      called later (but so far it has not been called later).
      
      Straighten this out: make it available to all configs, with a sensible
      default in asm-generic/pgtable.h, removing its definitions from those
      arches (arc, arm, arm64, sparc, tile) which are served by the default,
      adding #define has_transparent_hugepage has_transparent_hugepage to
      those (mips, powerpc, s390, x86) which need to override the default at
      runtime, and removing the __init from mips (but maybe that kind of code
      should be avoided after init: set a static variable the first time it's
      called).

      x86/cpufeature, x86/mm/pkeys: Fix broken compile-time disabling of pkeys · e8df1a95
      Dave Hansen 提交于
      When I added support for the Memory Protection Keys processor
      feature, I had to reindent the REQUIRED/DISABLED_MASK macros, and
      also consult the later cpufeature words.
      
      I'm not quite sure how I bungled it, but I consulted the wrong
      word at the end.  This only affected required or disabled cpu
      features in cpufeature words 14, 15 and 16.  So, only Protection
      Keys itself was screwed over here.
      
      The result was that if you disabled pkeys in your .config, you
      might still see some code show up that should have been compiled
      out.  There should be no functional problems, though.
      
      In verifying this patch I also realized that the DISABLE_PKU/OSPKE
      macros were defined backwards and that the cpu_has() check in
      setup_pku() was not doing the compile-time disabled checks.
      
      So also fix the macro for DISABLE_PKU/OSPKE and add a compile-time
      check for pkeys being enabled in setup_pku().

      KVM: halt_polling: provide a way to qualify wakeups during poll · 3491caf2
      Christian Borntraeger 提交于
      Some wakeups should not be considered a sucessful poll. For example on
      s390 I/O interrupts are usually floating, which means that _ALL_ CPUs
      would be considered runnable - letting all vCPUs poll all the time for
      transactional like workload, even if one vCPU would be enough.
      This can result in huge CPU usage for large guests.
      This patch lets architectures provide a way to qualify wakeups if they
      should be considered a good/bad wakeups in regard to polls.
      
      For s390 the implementation will fence of halt polling for anything but
      known good, single vCPU events. The s390 implementation for floating
      interrupts does a wakeup for one vCPU, but the interrupt will be delivered
      by whatever CPU checks first for a pending interrupt. We prefer the
      woken up CPU by marking the poll of this CPU as "good" poll.
      This code will also mark several other wakeup reasons like IPI or
      expired timers as "good". This will of course also mark some events as
      not sucessful. As  KVM on z runs always as a 2nd level hypervisor,
      we prefer to not poll, unless we are really sure, though.
      
      This patch successfully limits the CPU usage for cases like uperf 1byte
      transactional ping pong workload or wakeup heavy workload like OLTP
      while still providing a proper speedup.
      
      This also introduced a new vcpu stat "halt_poll_no_tuning" that marks
      wakeups that are considered not good for polling.

      x86/extable: ensure entries are swapped completely when sorting · 50c73890
      Mathias Krause 提交于
      The x86 exception table sorting was changed in commit 29934b0f
      ("x86/extable: use generic search and sort routines") to use the arch
      independent code in lib/extable.c.  However, the patch was mangled
      somehow on its way into the kernel from the last version posted at [1].
      The committed version kind of attempted to incorporate the changes of
      commit 548acf19 ("x86/mm: Expand the exception table logic to allow
      new handling options") as in _completely_ _ignoring_ the x86 specific
      'handler' member of struct exception_table_entry.  This effectively
      broke the sorting as entries will only partly be swapped now.
      
      Fortunately, the x86 Kconfig selects BUILDTIME_EXTABLE_SORT, so the
      exception table doesn't need to be sorted at runtime. However, in case
      that ever changes, we better not break the exception table sorting just
      because of that.
      
      [ Ard Biesheuvel points out that BUILDTIME_EXTABLE_SORT applies to the
        core image only, but we still rely on the sorting routines for modules
        in that case - Linus ]
      
      Fix this by providing a swap_ex_entry_fixup() macro that takes care of
      the 'handler' member.

      x86/KASLR: Build identity mappings on demand · 3a94707d
      Kees Cook 提交于
      Currently KASLR only supports relocation in a small physical range (from
      16M to 1G), due to using the initial kernel page table identity mapping.
      To support ranges above this, we need to have an identity mapping for the
      desired memory range before we can decompress (and later run) the kernel.
      
      32-bit kernels already have the needed identity mapping. This patch adds
      identity mappings for the needed memory ranges on 64-bit kernels. This
      happens in two possible boot paths:
      
      If loaded via startup_32(), we need to set up the needed identity map.
      
      If loaded from a 64-bit bootloader, the bootloader will have already
      set up an identity mapping, and we'll start via the compressed kernel's
      startup_64(). In this case, the bootloader's page tables need to be
      avoided while selecting the new uncompressed kernel location. If not,
      the decompressor could overwrite them during decompression.
      
      To accomplish this, we could walk the pagetable and find every page
      that is used, and add them to mem_avoid, but this needs extra code and
      will require increasing the size of the mem_avoid array.
      
      Instead, we can create a new set of page tables for our own identity
      mapping instead. The pages for the new page table will come from the
      _pagetable section of the compressed kernel, which means they are
      already contained by in mem_avoid array. To do this, we reuse the code
      from the uncompressed kernel's identity mapping routines.
      
      The _pgtable will be shared by both the 32-bit and 64-bit paths to reduce
      init_size, as now the compressed kernel's _rodata to _end will contribute
      to init_size.
      
      To handle the possible mappings, we need to increase the existing page
      table buffer size:
      
      When booting via startup_64(), we need to cover the old VO, params,
      cmdline and uncompressed kernel. In an extreme case we could have them
      all beyond the 512G boundary, which needs (2+2)*4 pages with 2M mappings.
      And we'll need 2 for first 2M for VGA RAM. One more is needed for level4.
      This gets us to 19 pages total.
      
      When booting via startup_32(), KASLR could move the uncompressed kernel
      above 4G, so we need to create extra identity mappings, which should only
      need (2+2) pages at most when it is beyond the 512G boundary. So 19
      pages is sufficient for this case as well.
      
      The resulting BOOT_*PGT_SIZE defines use the "_SIZE" suffix on their
      names to maintain logical consistency with the existing BOOT_HEAP_SIZE
      and BOOT_STACK_SIZE defines.

      x86/boot: Split out kernel_ident_mapping_init() · cf4fb15b
      Yinghai Lu 提交于
      In order to support on-demand page table creation when moving the
      kernel for KASLR, we need to use kernel_ident_mapping_init() in the
      decompression code.
      
      This splits it out into its own file for use outside of init_64.c.
      Additionally, checking for __pa/__va defines is added since they
      need to be overridden in the decompression code.
