Depending on platform firmware, a zap shader may not be required to take the GPU out of secure mode on boot, in which case we can just write RBBM_SECVID_TRUST_CNTL directly. Which we *mostly* handled, but missed clearing 'ret' resulting that hw_init() returned an error on these devices. Fixes: abccb9fe ("drm/msm/a6xx: Add zap shader load") Acked-by:

As discussed with Nicholas and Daniel Vetter (patchwork link to discussion below), the VRR timestamping behaviour produced utterly useless and bogus vblank/pageflip timestamps. We have found a way to fix this and provide sane behaviour. As of Linux 5.2, the amdgpu driver will be able to provide exactly the same vblank / pageflip timestamp semantic in variable refresh rate mode as in standard fixed refresh rate mode. This is achieved by deferring core vblank handling (drm_crtc_handle_vblank()) until the end of front porch, and also defer the sending of pageflip completion events until end of front porch, when we can safely compute correct pageflip/vblank timestamps. The same approach will be possible for other VRR capable kms drivers, so we can actually have sane and useful timestamps in VRR mode. This patch removes the section of the docs that describes the broken timestamp behaviour present in Linux 5.0/5.1.

Asking the GPU to busywait on a memory address, perhaps not unexpectedly in hindsight for a shared system, leads to bus contention that affects CPU programs trying to concurrently access memory. This can manifest as a drop in transcode throughput on highly over-saturated workloads. The only clue offered by perf, is that the bus-cycles (perf stat -e bus-cycles) jumped by 50% when enabling semaphores. This corresponds with extra CPU active cycles being attributed to intel_idle's mwait. This patch introduces a heuristic to try and detect when more than one client is submitting to the GPU pushing it into an oversaturated state. As we already keep track of when the semaphores are signaled, we can inspect their state on submitting the busywait batch and if we planned to use a semaphore but were too late, conclude that the GPU is overloaded and not try to use semaphores in future requests. In practice, this means we optimistically try to use semaphores for the first frame of a transcode job split over multiple engines, and fail if there are multiple clients active and continue not to use semaphores for the subsequent frames in the sequence. Periodically, we try to optimistically switch semaphores back on whenever the client waits to catch up with the transcode results.

Very similar, but of smaller magnitude, results are observed on both Skylake(gt2) and Kabylake(gt4). This may be due to the reduced impact of bus-cycles, where we see a 50% hit on Broxton, it is only 10% on the big core, in this particular test. One observation to make here is that for a greedy client trying to maximise its own throughput, using semaphores is the right choice. It is only the holistic system-wide view that semaphores of one client impacts another and reduces the overall throughput where we would choose to disable semaphores. The most noticeable negactive impact this has is on the no-op microbenchmarks, which are also very notable for having no cpu bus load. In particular, this increases the runtime and energy consumption of gem_exec_whisper.

Currently we submit the semaphore busywait as soon as the signaler is submitted to HW. However, we may submit the signaler as the tail of a batch of requests, and even not as the first context in the HW list, i.e. the busywait may start spinning far in advance of the signaler even starting. If we wait until the request before the signaler is completed before submitting the busywait, we prevent the busywait from starting too early, if the signaler is not first in submission port. To handle the case where the signaler is at the start of the second (or later) submission port, we will need to delay the execution callback until we know the context is promoted to port0. A challenge for later. Fixes: e8861964 ("drm/i915: Use HW semaphores for inter-engine synchronisation on gen8+") Signed-off-by:

Depends on GEN family and I915_PARAM_HAS_CONTEXT_ISOLATION, Mesa driver will decide whether constant buffer 0 address is relative or absolute, and load GPU initial state by lri to context mmio INSTPM (GEN8) or 0x20D8 (>=GEN9). Mesa Commit fa8a764b62 ("i965: Use absolute addressing for constant buffer 0 on Kernel 4.16+.") INSTPM is already added to gen8_engine_mmio_list, but 0x20D8 is missed in gen9_engine_mmio_list.
