      drm/i915/gvt: exclude cfg space from failsafe mode · f8572690
      Changbin Du authored
      When test GVTg as below scenario:
        VM boot --> failsafe --> kill qemu --> VM boot.
      Qemu report error at the second boot:
        ERROR: PCI region size must be pow2 type=0x0, size=0x1fa1000
      
      Qemu need access PCI_ROM_ADDRESS reg to determine the size of expansion
      PCI rom. The mechanism just like the BAR reg (write-read) and we should
      return the size 0 since we have no rom. If we reject the write to
      PCI_ROM_ADDRESS, Qemu cannot get the correct size of rom.
      
      Essentially, GVTg failsafe mode should not break PCI function. So we
      exclude cfg space from failsafe mode. This can fix above issue.
      
      v2: add Fixes and Bugzilla link.

      drm/i915/gvt: Activate/de-activate vGPU in mdev ops. · b79c52ae
      Zhi Wang authored
      This patch introduces two functions for activating/de-activating vGPU in
      mdev ops.
      
      A racing condition was found between virtual vblank emulation and KVGMT
      mdev release path. V-blank emulation will emulate and inject V-blank
      interrupt for every active vGPU with holding gvt->lock, while in mdev
      release path, it will directly release hypervisor handle without changing
      vGPU status or taking gvt->lock, so a kernel oops is encountered when
      vblank emulation is injecting a interrupt with a invalid hypervisor
      handle. (Reported by Terrence)
      
      To solve this problem, we factor out vGPU activation/de-activation from
      vGPU creation/destruction path and let KVMGT mdev release ops de-activate
      the vGPU before release hypervisor handle. Once a vGPU is de-activated,
      GVT-g will not emulate v-blank for it or touch the hypervisor handle.
      
      Fixes: 659643f7 ("drm/i915/gvt/kvmgt: add vfio/mdev support to KVMGT")
