When updating the bookkeeping following the reset, we need the seqno to be coherent on the CPU prior to trusting its result for deciding whether any request is completed. We need the irq_barrier before we start making these decisions, i.e. in reset_prepare. References: https://bugs.freedesktop.org/show_bug.cgi?id=99733Signed-off-by:

As dmabufs may live beyond the PCI device removal, we need to flush the freed object worker on device release, and include a warning in case there is a leak. Signed-off-by:

We may unload the PCI device before all users (such as dma-buf) are completely shutdown. This may leave VMA in the global GTT which we want to revoke, whilst keeping the objects themselves around to service the dma-buf. Signed-off-by:

We may need to keep our memory management alive after we have unloaded the physical pci device. For example, if we have exported an object via dmabuf, that will keep the device around but the pci device may be removed before the dmabuf itself is released, use of the pci hardware will be revoked, but the memory and object management needs to persist for the dmabuf.

This adds a file in i915's debugfs directory that allows userspace to manually control HPD storm detection. This is mainly for hotplugging tests, where we might want to test HPD storm functionality or disable storm detection to speed up hotplugging tests without breaking anything. Changes since v1: - Make HPD storm interval configurable - Misc code cleanup Signed-off-by:

Until recently vlv_steal_power_sequencer() wasn't being called for normal DP ports, and hence it could assert that it should only be called for pipe A and B (since pipe C doesn't support eDP). However that changed when we started to consider normal DP ports as well when choosing a PPS. So we will now get spurious warnings when vlv_steal_power_sequencer() does get called for pipe C. Avoid this by moving the WARN down into vlv_detach_power_sequencer() where this assertion should still hold.

Now that we have fast top-down insertion into the drm_mm, we can use it for frequent runtime operations like insertion of the context object, whereas before we limited it to the one-off insertion of the pinned kernel context. Keeping the active context objects out of the mappable region of the global GTT (except under memory pressure) improves our ability to allocate mappable aperture region without triggering a GPU stall.

When ttm_bo_init() fails, the reservation mutex should be unlocked. In debug build, the kernel reported "possible recursive locking detected" in this codepath. For debugging purposes, I also added a "WARN_ON(ww_mutex_is_locked())" when ttm_bo_init() fails and the mutex was locked as expected. This should fix (random) GPU hangs. The easy way to reproduce the issue is to change the "Super Sampling" option from 1.0 to 2.0 in Hitman. It will create a huge buffer, evict a bunch of buffers (around ~5k) and deadlock. This regression has been introduced pretty recently. v2: only release the mutex if resv is NULL Fixes: 12a852219583 ("drm/amdgpu: improve AMDGPU_GEM_CREATE_VRAM_CLEARED handling (v2)") Reviewed-by: -

i915 is pretty much feature complete. Support for atomic i915-specific connector properties is still missing; those properties can (for now) only be set through the legacy ioctl. ILK style watermarks and gen9+ watermarks are handled atomically, and nonblocking modesets work. FBC has also been made to work with atomic. gen4x- and vlv/chv watermarks still need to be fixed, so disable atomic by default there for now. Flip the switch!! Signed-off-by:

My randconfig tests on linux-next showed a newly introduced warning: drivers/gpu/drm/amd/amdgpu/amdgpu_object.c: In function 'amdgpu_bo_create_restricted': drivers/gpu/drm/amd/amdgpu/amdgpu_object.c:377:2: error: #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance thanks to write-combining [-Werror=cpp] Generally speaking, warnings about bad kernel configuration are not particularly helpful. We could enforce the selection of X86_PAT through Kconfig, so the driver cannot even be used unless it is enabled, or we could just rely on the runtime warning that is also there. In this version, I'm making the warning conditional on CONFIG_COMPILE_TEST, which shuts it up for me, but not people that may actually want to run the kernel as a compromize.
