      KVM: arm/arm64: Allow setting the timer IRQ numbers from userspace · 99a1db7a
      Christoffer Dall 提交于
      First we define an ABI using the vcpu devices that lets userspace set
      the interrupt numbers for the various timers on both the 32-bit and
      64-bit KVM/ARM implementations.
      
      Second, we add the definitions for the groups and attributes introduced
      by the above ABI.  (We add the PMU define on the 32-bit side as well for
      symmetry and it may get used some day.)
      
      Third, we set up the arch-specific vcpu device operation handlers to
      call into the timer code for anything related to the
      KVM_ARM_VCPU_TIMER_CTRL group.
      
      Fourth, we implement support for getting and setting the timer interrupt
      numbers using the above defined ABI in the arch timer code.
      
      Fifth, we introduce error checking upon enabling the arch timer (which
      is called when first running a VCPU) to check that all VCPUs are
      configured to use the same PPI for the timer (as mandated by the
      architecture) and that the virtual and physical timers are not
      configured to use the same IRQ number.

      KVM: arm/arm64: Move timer IRQ default init to arch_timer.c · 85e69ad7
      Christoffer Dall 提交于
      We currently initialize the arch timer IRQ numbers from the reset code,
      presumably because we once intended to model multiple CPU or SoC types
      from within the kernel and have hard-coded reset values in the reset
      code.
      
      As we are moving towards userspace being in charge of more fine-grained
      CPU emulation and stitching together the pieces needed to emulate a
      particular type of CPU, we should no longer have a tight coupling
      between resetting a VCPU and setting IRQ numbers.
      
      Therefore, move the logic to define and use the default IRQ numbers to
      the timer code and set the IRQ number immediately when creating the
      VCPU.

      KVM: arm: Handle VCPU device attributes in guest.c · 2227e439
      Christoffer Dall 提交于
      As we are about to support VCPU attributes to set the timer IRQ numbers
      in guest.c, move the static inlines for the VCPU attributes handlers
      from the header file to guest.c.

      uapi: export all arch specifics directories · 61562f98
      Nicolas Dichtel 提交于
      This patch removes the need of subdir-y. Now all files/directories under
      arch/<arch>/include/uapi/ are exported.
      
      The only change for userland is the layout of the command 'make
      headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
      Those new directories contains all files/directories of the specified arch.
      
      Note that only cris and tile have more directories than only asm:
       - arch-v[10|32] for cris;
       - arch for tile.

      uapi: export all headers under uapi directories · fcc8487d
      Nicolas Dichtel 提交于
      Regularly, when a new header is created in include/uapi/, the developer
      forgets to add it in the corresponding Kbuild file. This error is usually
      detected after the release is out.
      
      In fact, all headers under uapi directories should be exported, thus it's
      useless to have an exhaustive list.
      
      After this patch, the following files, which were not exported, are now
      exported (with make headers_install_all):

      For the record, note that exported files for asm directories are a mix of

       - arch/<arch>/include/uapi/asm/Kbuild;
       - arch/<arch>/include/asm/Kbuild.
