      KVM: PPC: Book3S PR: Make instruction fetch fallback work for system calls · 8b23de29
      Paul Mackerras 提交于
      It turns out that if we exit the guest due to a hcall instruction (sc 1),
      and the loading of the instruction in the guest exit path fails for any
      reason, the call to kvmppc_ld() in kvmppc_get_last_inst() fetches the
      instruction after the hcall instruction rather than the hcall itself.
      This in turn means that the instruction doesn't get recognized as an
      hcall in kvmppc_handle_exit_pr() but gets passed to the guest kernel
      as a sc instruction.  That usually results in the guest kernel getting
      a return code of 38 (ENOSYS) from an hcall, which often triggers a
      BUG_ON() or other failure.
      
      This fixes the problem by adding a new variant of kvmppc_get_last_inst()
      called kvmppc_get_last_sc(), which fetches the instruction if necessary
      from pc - 4 rather than pc.

      KVM: PPC: Book3S PR: Don't corrupt guest state when kernel uses VMX · 9d1ffdd8
      Paul Mackerras 提交于
      Currently the code assumes that once we load up guest FP/VSX or VMX
      state into the CPU, it stays valid in the CPU registers until we
      explicitly flush it to the thread_struct.  However, on POWER7,
      copy_page() and memcpy() can use VMX.  These functions do flush the
      VMX state to the thread_struct before using VMX instructions, but if
      this happens while we have guest state in the VMX registers, and we
      then re-enter the guest, we don't reload the VMX state from the
      thread_struct, leading to guest corruption.  This has been observed
      to cause guest processes to segfault.
      
      To fix this, we check before re-entering the guest that all of the
      bits corresponding to facilities owned by the guest, as expressed
      in vcpu->arch.guest_owned_ext, are set in current->thread.regs->msr.
      Any bits that have been cleared correspond to facilities that have
      been used by kernel code and thus flushed to the thread_struct, so
      for them we reload the state from the thread_struct.
      
      We also need to check current->thread.regs->msr before calling
      giveup_fpu() or giveup_altivec(), since if the relevant bit is
      clear, the state has already been flushed to the thread_struct and
      to flush it again would corrupt it.

      KVM: PPC: Book3S HV: Allow negative offsets to real-mode hcall handlers · 4baa1d87
      Paul Mackerras 提交于
      The table of offsets to real-mode hcall handlers in book3s_hv_rmhandlers.S
      can contain negative values, if some of the handlers end up before the
      table in the vmlinux binary.  Thus we need to use a sign-extending load
      to read the values in the table rather than a zero-extending load.
      Without this, the host crashes when the guest does one of the hcalls
      with negative offsets, due to jumping to a bogus address.

      KVM: PPC: Book3S HV: Correct tlbie usage · 54480501
      Paul Mackerras 提交于
      This corrects the usage of the tlbie (TLB invalidate entry) instruction
      in HV KVM.  The tlbie instruction changed between PPC970 and POWER7.
      On the PPC970, the bit to select large vs. small page is in the instruction,
      not in the RB register value.  This changes the code to use the correct
      form on PPC970.
      
      On POWER7 we were calculating the AVAL (Abbreviated Virtual Address, Lower)
      field of the RB value incorrectly for 64k pages.  This fixes it.
      
      Since we now have several cases to handle for the tlbie instruction, this
      factors out the code to do a sequence of tlbies into a new function,
      do_tlbies(), and calls that from the various places where the code was
      doing tlbie instructions inline.  It also makes kvmppc_h_bulk_remove()
      use the same global_invalidates() function for determining whether to do
      local or global TLB invalidations as is used in other places, for
      consistency, and also to make sure that kvm->arch.need_tlb_flush gets
      updated properly.

         transitions is *the* way to control pins and multiplexing.

       - Two pin control states related to power management are now handled in
         the device core: "sleep" and "idle", removing a lot of boilerplate
         code in drivers.  We do not yet know if this is the final word for
         pin PM, but it already make things a lot easier to handle.

       "A small but useful set of regmap updates this time around:
      
         - An abstraction for bitfields within a register map contributed by
           Srinivas Kandagatla, allowing drivers to cope more easily when
           hardware designers randomly move things about (mainly when talking
           to things like system controllers).
      
         - Changes from Lars-Peter Clausen to allow the MMIO regmap to be used
           from hard IRQ context.
      
         - Small improvements to the cache infrastructure and performance,
           including a default cache sync operation so now all regmaps can
           sync easily.
      
        There's also a pinctrl driver making use of the new bitfield API,
        merged here for dependency reasons.  There will be a simple add/add
        conflict with the pinctrl tree as a result."

       "This contains the usual updates from other people (listed below) and
        the usual random muddle of miscellaneous ARM updates which cover some
        low priority bug fixes and performance improvements.
      
        I've started to put the pull request wording into the merge commits,
        which are:
      
         - NoMMU stuff:
      
           This includes the following series sent earlier to the list:
            - nommu-fixes
            - R7 Support
            - MPU support
      
           I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I
           were discussing today until we've reached a conclusion/that's had
           some more review.
      
           This is rebased (and re-tested) on your devel-stable branch because
           otherwise there were going to be conflicts with Uwe's V7M work now
           that you've merged that.  I've included the fix for limiting MPU to
           CPU_V7.
      
         - Huge page support
      
           These changes bring both HugeTLB support and Transparent HugePage
           (THP) support to ARM.  Only long descriptors (LPAE) are supported
           in this series.
      
           The code has been tested on an Arndale board (Exynos 5250).
      
         - LPAE updates
      
           Please pull these miscellaneous LPAE fixes I've been collecting for
           a while now for 3.11.  They've been tested and reviewed by quite a
           few people, and most of the patches are pretty trivial.  -- Will Deacon.
      
         - arch_timer cleanups
      
           Please pull these arch_timer cleanups I've been holding onto for a
           while.  They're the same as my last posting, but have been rebased
           to v3.10-rc3.
      
         - mpidr linearisation (multiprocessor id register - identifies which
           CPU number we are in the system)
      
           This patch series that implements MPIDR linearization through a
           simple hashing algorithm and updates current cpu_{suspend}/{resume}
           code to use the newly created hash structures to retrieve context
           pointers.  It represents a stepping stone for the implementation of
           power management code on forthcoming multi-cluster ARM systems.
      
           It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
           OMAP4 and Tegra, with processors hitting low-power states requiring
           warm-boot resume through the cpu_resume code path"
