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") Signed-off-by:

In my previous Commit ab9da627906a ("drm/i915: make context status notifier head be per engine") rely on scheduler->current_workload[x] to distinguish gvt spacial request from i915 request. But this is not always true since no synchronization between workload_thread and lrc irq handler. lrc irq handler workload_thread ---- ---- pick i915 requests; intel_vgpu_submit_execlist(); current_workload[x] = xxx; shadow_context_status_change(); Then current_workload[x] is not null but current request is of i915 self. So instead we check ctx flag CONTEXT_FORCE_SINGLE_SUBMISSION. Only gvt request set this flag and always set. v2: Reverse the order of multi-condition 'if' statement.

The kvmgt code keeps a pointer to the struct kvm associated with the device, but doesn't actually hold a reference to it. If we do unclean shutdown testing (ie. killing the user process), then we can see the kvm association to the device unset, which causes kvmgt to trigger a device release via a work queue. Naturally we cannot guarantee that the cached struct kvm pointer is still valid at this point without holding a reference. The observed failure in this case is a stuck cpu trying to acquire the spinlock from the invalid reference, but other failure modes are clearly possible. Hold a reference to avoid this.

When handling guest request, GVT needs to populate/update shadow_ctx with guest context. This behavior needs to make sure the shadow_ctx is pinned. The current implementation is relying on i195 allocate request to pin but this way cannot guarantee the i915 not to unpin the shadow_ctx when GVT update the guest context from shadow_ctx. So GVT should pin/unpin the shadow_ctx by itself. Signed-off-by:

It looks like we were incorrectly comparing vma->node against itself instead of the target node, when evicting for a node on systems where we need guard pages between regions with different cache domains. As a consequence we can end up trying to needlessly evict neighbouring nodes, even if they have the same cache domain, and if they were pinned we would fail the eviction.

Before we instantiate/pin the backing store for our use, we can prepopulate the shmemfs filp efficiently using a write into the pagecache. We avoid the penalty of instantiating all the pages, important if the user is just writing to a few and never uses the object on the GPU, and using a direct write into shmemfs allows it to avoid the cost of retrieving a page (mostly the clear-before-use, but in theory we could curtail swapin) before it is overwritten. This can be extended later to provide additional specialisation for other backends (other than shmemfs). For now it provides a defense against very large write-only allocations from exhausting all of system memory. v2: Smelling fixes.

Certain Baytrails, namely the 4 cpu core variants, have been plaqued by spurious system hangs, mostly occurring with light loads. Multiple bisects by various people point to a commit which changes the reclocking strategy for Baytrail to follow its bigger brethen: commit 8fb55197 ("drm/i915: Agressive downclocking on Baytrail") There is also a review comment attached to this commit from Deepak S on avoiding punit access on Cherryview and thus it was excluded on common reclocking path. By taking the same approach and omitting the punit access by not tweaking the thresholds when the hardware has been asked to move into different frequency, considerable gains in stability have been observed. With J1900 box, light render/video load would end up in system hang in usually less than 12 hours. With this patch applied, the cumulative uptime has now been 34 days without issues. To provoke system hang, light loads on both render and bsd engines in parallel have been used: glxgears >/dev/null 2>/dev/null & mpv --vo=vaapi --hwdec=vaapi --loop=inf vid.mp4 So far, author has not witnessed system hang with above load and this patch applied. Reports from the tenacious people at kernel bugzilla are also promising. Considering that the punit access frequency with this patch is considerably less, there is a possibility that this will push the, still unknown, root cause past the triggering point on most loads. But as we now can reliably reproduce the hang independently, we can reduce the pain that users are having and use a static thresholds until a root cause is found. v3: don't break debugfs and simplification (Chris Wilson) References: https://bugzilla.kernel.org/show_bug.cgi?id=109051 Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Len Brown <len.brown@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Jani Nikula <jani.nikula@intel.com> Cc: fritsch@xbmc.org Cc: miku@iki.fi Cc: Ezequiel Garcia <ezequiel@vanguardiasur.com.ar> CC: Michal Feix <michal@feix.cz> Cc: Hans de Goede <hdegoede@redhat.com> Cc: Deepak S <deepak.s@linux.intel.com> Cc: Jarkko Nikula <jarkko.nikula@linux.intel.com> Cc: <stable@vger.kernel.org> # v4.2+ Acked-by:

Per PCI specification, Configuration Register has different types (RO, RW, RW1C, Rsvd). For RO Register bits are read-only and cannot be altered by software. For RW1C Register bits indicate status when read. A Set bit indicates a status event which is Cleared by writing a 1b. Writing a 0b to RW1C bits has no effect. Reserved Register is for future implementations, and they are read-only and must return zero when read. Current vGPU configuration write emulation just copy the value as it is. So we haven't emulated RO, RW1C and Rsvd Registers correctly. This patch is following the Spec to correct emulation logic. We add a function vgpu_cfg_mem_write to wrap the access to vGPU configuration memory. The write function uses a RW Register bitmap to avoid RO bits be overwritten, and emulate RW1C behavior for the particular status Register. v2: new = src[i] --> new = src[i] & mask (zhenyu) Signed-off-by:

With this mechanism, gvt should wait until the GVT request seqno passed before complete the current workload. So that there should be a context switch interrupt come before gvt free the workload. In this way, workload lifecylce matches with the i915 request lifecycle. The workload can only be freed after the request is completed. v2: use gvt_dbg_sched instead of gvt_err to print when wait again Signed-off-by:
