Now that the error capture is fully decoupled from fence signalling (request retirement to free memory, which in turn depends on resets) we can safely flush the G2H handler during a GT reset. This eliminates corner cases where GuC generated G2H (e.g. engine resets) race with a GT reset. v2: (John Harrison) - Fix typo in commit message (s/is/in) Signed-off-by:

The G2H handler needs to be flushed during a GT reset but a G2H indicating engine reset failure can trigger a GT reset. Add a worker to trigger the GT rest when an engine reset failure is received to break this circular dependency. v2: (John Harrison) - Store engine reset mask - Fix typo in commit message v3: (John Harrison) - Fix another typo in commit message - s/reset_*/reset_fail_*/ Signed-off-by:

In the i915 there are several hacks in place to make request cancellation work with an old version of the GuC which delivered the G2H indicating schedule disable is done before G2H indicating a context reset. Version 69 fixes this, so we can remove these hacks. v2: (Checkpatch) - s/cancelation/cancellation Reviewed-by:

Add a flag PIN_VALIDATE, to indicate we don't need to pin and only protected by the object lock. This removes the need to unpin, which is done by just releasing the lock. eb_reserve is slightly reworked for readability, but the same steps are still done: - First pass pins with NONBLOCK. - Second pass unbinds all objects first, then pins. - Third pass is only called when not all objects are softpinned, and unbinds all objects, then calls i915_gem_evict_vm(), then pins. Changes since v1: - Split out eb_reserve() into separate functions for readability. Changes since v2: - Make batch buffer mappable on platforms where only GGTT is available, to prevent moving the batch buffer during relocations. Changes since v3: - Preserve current behavior for batch buffer, instead be cautious when calling i915_gem_object_ggtt_pin_ww, and re-use the current batch vma if it's inside ggtt and map-and-fenceable. - Remove impossible condition check from eb_reserve. (Matt) Changes since v5: - Do not even temporarily pin, just call i915_gem_evict_vm() and mark all vma's as unpinned. Signed-off-by:

We want to remove more members of i915_vma, which requires the locking to be held more often. Start requiring gem object lock for i915_vma_unbind, as it's one of the callers that may unpin pages. Some special care is needed when evicting, because the last reference to the object may be held by the VMA, so after __i915_vma_unbind, vma may be garbage, and we need to cache vma->obj before unlocking. Changes since v1: - Make trylock failing a WARN. (Matt) - Remove double i915_vma_wait_for_bind() (Matt) - Move atomic_set to right before mutex_unlock(), to make it more clear they belong together.

Because we will start to require the obj->resv lock for unbinding, ensure these vma eviction utility functions also take the lock. This requires some function signature changes, to ensure that the ww context is passed around, but is mostly straightforward. Previously this was split up into several patches, but reworking should allow for easier bisection. Changes since v1: - Handle evicting dead objects better. Signed-off-by:

i915_gem_evict_vm will need to be able to evict objects that are locked by the current ctx. By testing if the current context already locked the object, we can do this correctly. This allows us to evict the entire vm even if we already hold some objects' locks. Previously, this was spread over several commits, but it makes more sense to commit the changes to i915_gem_evict_vm separately from the changes to i915_gem_evict_something() and i915_gem_evict_for_node(). Changes since v1: - Handle evicting dead objects better. Changes since v2: - Use for_i915_gem_ww in igt_evict_vm. (Thomas) Signed-off-by:

Now that we cannot unbind kill the currently locked object directly because we're removing short term pinning, we may have to unbind the object from gtt manually, using a i915_gem_evict_vm() call. Changes since v1: - Remove -ENOSPC warning, can still happen with concurrent mmaps where we can't unbind the other mmap because of the lock held. This fixes the gem_mmap_gtt@cpuset tests.

Even if it's probably not really useful, it can get selected by e.g. randconfig builds, and then failing to compile is an annoyance. Unfortunately, it's hard to fix in Kconfig, since DRM_TTM is selected by many things that don't really depend on any specific architecture, and just depend on PCI (which is indeed now available in ARCH=um via simulation/emulation). Fix this in the code instead by just ifdef'ing the relevant two lines that depend on "real X86". Reported-by:

The vga16fb framebuffer driver only supports Enhanced Graphics Adapter (EGA) and Video Graphics Array (VGA) 16 color graphic cards. But it doesn't check if the adapter is one of those or if a VGA16 mode is used. This means that the driver will be probed even if a VESA BIOS Extensions (VBE) or Graphics Output Protocol (GOP) interface is used. This issue has been present for a long time but it was only exposed by commit d391c582 ("drivers/firmware: move x86 Generic System Framebuffers support") since the platform device registration to match the {vesa,efi}fb drivers is done later as a consequence of that change. All non-x86 architectures though treat orig_video_isVGA as a boolean so only do the supported video mode check for x86 and not for other arches.

For some reason this file isn't using the appropriate register headers for DCN headers, which means that on DCN2 we're getting the VIEWPORT_DIMENSION offset wrong. This means that we're not correctly carving out the framebuffer memory correctly for a framebuffer allocated by EFI and therefore see corruption when loading amdgpu before the display driver takes over control of the framebuffer scanout. Fix this by checking the DCE_HWIP and picking the correct offset accordingly. Long-term we should expose this info from DC as GMC shouldn't need to know about DCN registers.

The remove_list head was only used for keeping track of existing ranges that are to be removed from the svms->list. The update_list was used for new or existing ranges that need updated attributes. These two cases are mutually exclusive (i.e. the same range will never be on both lists).

There are seven list_heads in struct svm_range: list, update_list, remove_list, insert_list, svm_bo_list, deferred_list, child_list. This patch and the next one remove two of them that are redundant. The insert_list head was only used for new ranges that are not on the svms->list yet. So we can use that list head for keeping track of new ranges before they get added, and use list_move_tail to move them to the svms->list when ready. Signed-off-by:
