This rename makes it more clear that everything initialized in the _init function must be cleaned up in a6xx_gmu_remove.

The gmu driver is initialized and cleaned up with calls from the gpu driver. As such, the platform device stays valid after a6xx_gmu_remove is called and the device managed resources are not freed. In the case of gpu probe failures or unbind, these resources will remain managed. If the gpu bind is run again (eg: if there's a probe defer somewhere in msm), these resources will be initialized again for the same device, creating multiple references. In the case of irqs, this causes failures since the irqs are not shared (nor should they be). This patch removes all devm_* calls and manually cleans things up in gmu_remove.

a6xx_gmu_stop() already calls this function via shutdown or force_stop, so it's not necessary to call it twice.

The driver checks for gmu->mmio as a sign that the device has been initialized, however there are failures in probe below the mmio init. If one of those is hit, mmio will be non-null but freed. In that case, a6xx_gmu_probe will return an error to a6xx_gpu_init which will in turn call a6xx_gmu_remove which checks gmu->mmio and tries to free resources for a second time. This causes a great boom. Fix this by adding an initialized member to gmu which is set on successful probe and cleared on removal.

To facilitate additional options to get_user_pages_fast() change the singular write parameter to be gup_flags. This patch does not change any functionality. New functionality will follow in subsequent patches. Some of the get_user_pages_fast() call sites were unchanged because they already passed FOLL_WRITE or 0 for the write parameter. NOTE: It was suggested to change the ordering of the get_user_pages_fast() arguments to ensure that callers were converted. This breaks the current GUP call site convention of having the returned pages be the final parameter. So the suggestion was rejected.

nv50_head_atomic_duplicate_state() makes a copy of nv50_head_atom struct. This patch adds copying of struct member named "or", which previously was left uninitialized in the duplicated structure. Due to this bug, incorrect nhsync and nvsync values were sometimes used. In my particular case, that lead to a mismatch between the output resolution of the graphics device (GeForce GT 630 OEM) and the reported input signal resolution on the display. xrandr reported 1680x1050, but the display reported 1280x1024. As a result of this mismatch, the output on the display looked like it was cropped (only part of the output was actually visible on the display). git bisect pointed to commit 2ca7fb5c ("drm/nouveau/kms/nv50: handle SetControlOutputResource from head"), which added the member "or" to nv50_head_atom structure, but forgot to copy it in nv50_head_atomic_duplicate_state().

Where possible, we want the failsafe link configuration (one which won't hang the OR during modeset because of not enough bandwidth for the mode) to also be supported by the sink.

HW has error checks in place which check that pixel depth is explicitly provided on DP, while HDMI has a "default" setting that we use. In multi-display configurations with identical modelines, but different protocols (HDMI + DP, in this case), it was possible for the DP head to get swapped to the head which previously drove the HDMI output, without updating HeadSetControlOutputResource(), triggering the error check and hanging the core update.

The driver currently sets register 0xfb (Low Refresh Rate) based on the value of mode->vrefresh. Firstly, this field is specified to be in Hz, but the magic numbers used by the code are Hz * 1000. This essentially leads to the low refresh rate always being set to 0x01, since the vrefresh value will always be less than 24000. Fix the magic numbers to be in Hz. Secondly, according to the comment in drm_modes.h, the field is not supposed to be used in a functional way anyway. Instead, use the helper function drm_mode_vrefresh().

Currently there is an underlying assumption that i915_request_unsubmit() is synchronous wrt the GPU -- that is the request is no longer in flight as we remove it. In the near future that may change, and this may upset our signaling as we can process an interrupt for that request while it is no longer in flight. CPU0 CPU1 intel_engine_breadcrumbs_irq (queue request completion) i915_request_cancel_signaling ... ... i915_request_enable_signaling dma_fence_signal Hence in the time it took us to drop the lock to signal the request, a preemption event may have occurred and re-queued the request. In the process, that request would have seen I915_FENCE_FLAG_SIGNAL clear and so reused the rq->signal_link that was in use on CPU0, leading to bad pointer chasing in intel_engine_breadcrumbs_irq. A related issue was that if someone started listening for a signal on a completed but no longer in-flight request, we missed the opportunity to immediately signal that request. Furthermore, as intel_contexts may be immediately released during request retirement, in order to be entirely sure that intel_engine_breadcrumbs_irq may no longer dereference the intel_context (ce->signals and ce->signal_link), we must wait for irq spinlock. In order to prevent the race, we use a bit in the fence.flags to signal the transfer onto the signal list inside intel_engine_breadcrumbs_irq. For simplicity, we use the DMA_FENCE_FLAG_SIGNALED_BIT as it then quickly signals to any outside observer that the fence is indeed signaled. v2: Sketch out potential dma-fence API for manual signaling v3: And the test_and_set_bit() Fixes: 52c0fdb2 ("drm/i915: Replace global breadcrumbs with per-context interrupt tracking") Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: NTvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190508112452.18942-1-chris@chris-wilson.co.uk (cherry picked from commit 0152b3b3) Signed-off-by: NJoonas Lahtinen <joonas.lahtinen@linux.intel.com>

On HSW the pipe A panel fitter lives inside the display power well, and the input MUX for the EDP transcoder needs to be configured appropriately to route the data through the power well as needed. Changing the MUX setting is not allowed while the pipe is active, so we need to force a full modeset whenever we need to change it. Currently we may end up doing a fastset which won't change the MUX settings, but it will drop the power well reference, and that kills the pipe.

On many (all?) the Gemini Lake systems we work with, there is frequent momentary graphical corruption at the top of the screen, and it seems that disabling framebuffer compression can avoid this. The ticket was reported 6 months ago and has already affected a multitude of users, without any real progress being made. So, lets disable framebuffer compression on GeminiLake until a solution is found.
