This was totally lost when I originally created the atomic helpers. We probably should also check possible_clones in the helpers, but since the legacy ones didn't do that this is for a separate patch.

2015-11-19Revert "drm/i915: skip modeset if compatible for everyone."Jani Nikula
This reverts commit 6764e9f8724f1231b4deac53b9a82286ac0830e7 Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Thu Aug 27 15:44:06 2015 +0200 drm/i915: skip modeset if compatible for everyone. Bring back the i915.fastboot module parameter, disabled by default, due to backlight regression on Chromebook Pixel 2015. Apparently the firmware of the Chromebook in question enables the panel but disables backlight to avoid a brief garbage scanout upon loading the kernel/module. With fastboot, we leave the backlight untouched, in this case disabled. The user would have to do a modeset (i.e. not just crank up the brightness) to enable the backlight. There is no clean fix readily available, so get back to the drawing board by reverting. [N.B.

2015-11-18drm/i915: Consider SPLL as another shared pll, v2.Maarten Lankhorst
When diagnosing a unrelated bug for someone on irc, it would seem the hardware can be brought up by the BIOS with the embedded displayport using the SPLL for spread spectrum. Right now this is not handled well in i915, and it calculates the crtc needs to be reprogrammed on the first modeset without SSC, but the SPLL itself was kept active. Fix this by exposing SPLL as a shared pll that will not be returned by intel_get_shared_dpll; you have to know it exists to use it. Changes since v1: - Create a separate dpll_hw_state.spll for spll, and use separate pll functions for spll.

2015-11-18drm/i915: Fix gpu frequency change tracingMika Kuoppala
With gen < 9 we have had always 50Mhz units as our hw ratio. With gen >= 9 the hw ratio changed to 16.667Mhz (50/3). The result was that our gpu frequency tracing started to output values 3 times larger than expected due to hardcoded scaling value. Fix this by using Use intel_gpu_freq() when generating Mhz value from ratio for 'intel_gpu_freq_change' trace event.

2015-11-17drm/i915: Don't clobber the addfb2 ioctl paramsVille Syrjälä
We try to convert the old way of of specifying fb tiling (obj->tiling) into the new fb modifiers. We store the result in the passed in mode_cmd structure. But that structure comes directly from the addfb2 ioctl, and gets copied back out to userspace, which means we're clobbering the modifiers that the user provided (all 0 since the DRM_MODE_FB_MODIFIERS flag wasn't even set by the user). Hence if the user reuses the struct for another addfb2, the ioctl will be rejected since it's now asking for some modifiers w/o the flag set. Fix the problem by making a copy of the user provided structure. We can play any games we want with the copy. IGT-Version: 1.12-git (x86_64) (Linux: 4.4.0-rc1-stereo+ x86_64) ...

2015-11-17drm/i915: Clear intel_crtc->atomic before updating it.Maarten Lankhorst
If an atomic update fails intel_crtc->atomic may have have some values left from the last atomic check. One example is atomic->wait_for_vblank, which results in spurious errors in kms_flip.

2015-11-16drm/amdgpu: fix incorrect mutex usage v3Christian König
Before this patch the scheduler fence was created when we push the job into the queue, so we could only get the fence after pushing it. The mutex now was necessary to prevent the thread pushing the jobs to the hardware from running faster than the thread pushing the jobs into the queue. Otherwise the thread pushing jobs into the queue would have accessed possible freed up memory when it tries to get a reference to the fence. So what you get in the end is thread A: mutex_lock(&job->lock); ... Kick of thread B. ... mutex_unlock(&job->lock); And thread B: mutex_lock(&job->lock); .... mutex_unlock(&job->lock); kfree(job); I'm actually not sure if I'm still up to date on this, but this usage pattern used to be not allowed with mutexes.

The amdgpu driver has a debugfs interface that shows the amount of VRAM in use, but the newly added code causes a build error on all 32-bit architectures: drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c:1076:17: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'long long int' [-Wformat=] This fixes the format string to use "%llu" for printing 64-bit numbers, which works everywhere, as long as we also cast to 'u64'.
