We never registered any kind of lid notifier for eDP, so looking at the lid status is pretty much bonkers. Let's just consider eDP always connected instead. Signed-off-by:

Ville Syrjälä authored
We broke the LVDS notifier resume thing in (presumably) commit e2c8b870 ("drm/i915: Use atomic helpers for suspend, v2.") as we no longer duplicate the current state in the LVDS notifier and thus we never resume it properly either. Instead of trying to fix it again let's just kill off the lid notifier entirely. None of the machines tested thus far have apparently needed it. Originally the lid notifier was added to work around cases where the VBIOS was clobbering some of the hardware state behind the driver's back, mostly on Thinkpads. We now have a few report of Thinkpads working just fine without the notifier. So maybe it was misdiagnosed originally, or something else has changed (ACPI video stuff perhaps?). If we do end up finding a machine where the VBIOS is still causing problems I would suggest that we first try setting various bits in the VBIOS scratch registers. There are several to choose from that may instruct the VBIOS to steer clear. With the notifier gone we'll also stop looking at the panel status in ->detect(). v2: Nuke enum modeset_restore (Rodrigo) Cc: stable@vger.kernel.org Cc: Wolfgang Draxinger <wdraxinger.maillist@draxit.de> Cc: Vito Caputo <vcaputo@pengaru.com> Cc: kitsunyan <kitsunyan@airmail.cc> Cc: Joonas Saarinen <jza@saunalahti.fi> Tested-by: Vito Caputo <vcaputo@pengaru.com> # Thinkapd X61s Tested-by: kitsunyan <kitsunyan@airmail.cc> # ThinkPad X200 Tested-by: Joonas Saarinen <jza@saunalahti.fi> # Fujitsu Siemens U9210 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=105902 References: https://lists.freedesktop.org/archives/intel-gfx/2018-June/169315.html References: https://bugs.freedesktop.org/show_bug.cgi?id=21230 Fixes: e2c8b870 ("drm/i915: Use atomic helpers for suspend, v2.")

There's a race between idling the engine and finishing off the last tasklet (as we may kick the tasklets after declaring an individual engine idle). However, since we do not need to access the device until we try to submit to the ELSP register (processing the CSB just requires normal CPU access to the HWSP, and when idle we should not need to submit!) we can defer the assertion unto that point. The assertion is still useful as it does verify that we do hold the longterm GT wakeref taken from request allocation until request completion.

If we call into the shrinker for direct relcaim inside kmalloc, it will retire the requests. If we retire the vma->last_active while processing a new i915_vma_move_to_active() we can upset the delicate bookkeeping required for the cache. After the possible invocation of the shrinker, we need to double check the vma->last_active is still valid.

We make a decision at module load whether to use the GuC backend or not, but lose that setup across set-wedge. Currently, the guc doesn't override the engine->set_default_submission hook letting execlists sneak back in temporarily on unwedging leading to an unbalanced park/unpark. v2: Remove comment about switching back temporarily to execlists on guc_submission_disable(). We currently only call disable on shutdown, and plan to also call disable before suspend and reset, in which case we will either restore guc submission or mark the driver as wedged, making the reset back to execlists pointless. v3: Move reset.prepare across Fixes: 63572937 ("drm/i915/execlists: Flush pending preemption events during reset") Testcase: igt/drv_module_reload/basic-reload-inject Testcase: igt/gem_eio Signed-off-by:

It was originally introduced following the VESA spec in order to validate PSR. However we found so many issues around sink_crc that instead of helping PSR development it only brought another layer of trouble to the table. So, sink_crc has been a black whole for us in question of time, effort and hope. First of the problems is that HW statement is clear: "Do not attempt to use aux communication with PSR enabled". So the main reason behind sink_crc is already compromised. For a while we had hope on the aux-mutex could workaround this problem on SKL+ platforms, but that mutex was not reliable, not tested, and we shouldn't use according to HW engineers. Also, nor source, nor sink designed and implemented the sink_crc to be used like we are trying to use here. Well, the sink side of things is also apparently not prepared for this case. Each panel that we tried seemed to have a different behavior with same code and same source. So, for all the time we lost on trying to ducktape all these different issues I believe it is now time to move PSR to a more reliable validation. Maybe not a perfect one as we dreamed for this sink_crc, but at least more reliable. Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by:

Our I915g (early gen3, the oldest machine we have in the farm) is still reporting occasional incoherency performing the following operations: 1) write through GGTT (indirect write into memory) 2) write through either CPU or WC (direct write into memory) 3) read from GGTT (indirect read) Instead of reporting the value from (2), the read from GGTT reports the earlier value written via the GGTT. We have made sure that the writes are flushed from the CPU (commit 3a32497f ("drm/i915/selftests: Provide full mb() around clflush") and commit add00e6d ("drm/i915: Flush the WCB following a WC write")), but still see the error, just less frequently. The only remaining cache that might be affected here is a chipset cache, so flush that as well. Testcase: igt/drv_selftest/live_coherency #gdg Signed-off-by:

Blending order is set based on the z position of each DRM plane. The blending order register is currently cleared at each atomic DRM commit, with the intent that each committed plane will set the appropriate bits (based on its z-pos) when enabling the plane. However, it sometimes happens that a particular plane is left unchanged by an atomic commit and thus will not be configured again. In that scenario, blending order is cleared and only the bits relevant for the planes affected by the commit are set. This leaves the planes that did not change without their blending order set in the register, leading to that plane not being displayed. Instead of clearing the blending order register at every atomic commit, this change moves the register's initial clear at bind time and only clears the bits for a specific plane when disabling it or changing its zpos. This way, planes that are left untouched by a DRM atomic commit are no longer disabled. Signed-off-by:

In the huge pages tests, we may have lots of objects being trapped on the freelist as we hold the struct_mutex allowing the free worker no opportunity to recover the backing store. We also have stricter requirements and the desire for large contiguous pages, further increasing the allocation pressure. To reduce the chance of running out of memory, we could either drop the mutex and flush the free worker, or we could release the backing store directly. We do the latter in this patch for simplicity.

This is something we've needed for a very long time now, as it makes debugging issues with faulty MST hubs along with debugging issues regarding us interfacing with hubs correctly vastly easier to debug. Currently this can actually be done if you trace the i2c devices for DP using ftrace but that's significantly less useful for a couple of reasons: - Tracing the i2c devices through ftrace means all of the traces are going to contain a lot of "garbage" output that we're sending over the i2c line. Most of this garbage comes from retrying transactions, DRM's helper library adding extra transactions to work around bad hubs, etc. - Having a user set up ftrace so that they can provide debugging information is a lot more difficult then being able to say "just boot with drm.debug=0x100" - We can potentially expand upon this tracing in the future to print debugging information in regards to other DP transactions like MST sideband transactions This is inspired by a patch Rob Clark sent to do this a long time back. Neither of us could find the patch however, so we both assumed it would probably just be easier to rewrite it anyway. Cc: Rob Clark <robdclark@gmail.com> Signed-off-by:

In the second reservation_object_add_shared_fence call, the BUG_ON triggers. However, nothing bad would happen in reservation_object_add_shared_inplace, since both fences are from the same context, so they only occupy a single slot.

If we declare the driver wedged before the GPU truly is, then we may see the GPU complete some CS events following our cancellation. This leaves us quite confused as we deleted all the bookkeeping and thus complain about the inconsistent state. We can just ignore the remaining events and let the GPU idle by not feeding it, and so avoid trying to racily overwrite shared state. We rely on there being a full GPU reset before unwedging, giving us the opportunity to reset the shared state. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107188Signed-off-by:
