All timestamps returned by GuC for GuC PMU busyness are captured from GUC PM TIMESTAMP. Since this timestamp does not tick when GuC goes idle, kmd uses RING_TIMESTAMP to measure busyness of an engine with an active context. In further stress testing, the MMIO read of the RING_TIMESTAMP is seen to cause a rare hang. Resolve the issue by using gt specific timestamp from PM which is in sync with the GuC PM timestamp.

Using more guc_ids in the stealing guc id test has no real benefit. Tearing down lots of contexts all at the same time takes a bit of time due to the H2G / G2H ping-pong with the GuC. On some slower platforms this can cause timeous when flushing the test as the GT isn't idle when this ping-pong is happening. Reduce the number of guc ids to speed up the flushing of the test.

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.

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.
