2021-12-03drm/i915/fbc: Nuke more FBC stateVille Syrjälä
There isn't a good reason why we'd have to cache all this plane state stuff in the FBC state. Instead we can just pre-calculate what FBC will really need.

2021-12-03drm/i915/fbc: Nuke lots of crap from intel_fbc_state_cacheVille Syrjälä
There's no need to store all this stuff in intel_fbc_state_cache. Just check it all against the plane/crtc states and store only what we need. Probably more should get nuked still, but this is a start. So what we'll do is: - each plane will check its own state and update its local no_fbc_reason - the per-plane no_fbc_reason (if any) then gets propagated to the cache->no_fbc_reason while doing the actual update - fbc->no_fbc_reason gets updated in the end with either the value from the cache or directly from frontbuffer tracking It's still a bit messy, but should hopefuly get cleaned up more in the future. At least now we can observe each plane's reasons for rejecting FBC now more consistently, and we don't have so mcuh redundant state store all over the place. v2: store no_fbc_reason per-plane instead of per-pipe Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211124113652.22090-4-ville.syrjala@linux.intel.com Reviewed-by: Mika Kahola <mika.kahola@intel.com>

2021-12-03drm/i915: Get rid of the 64bit PLANE_CC_VAL mmioVille Syrjälä
Let's just stick to 32bit mmio accesses so we can get rid of the bare "uncore" reg access in display code. The register are defined as 32bit in the spec anyway. We could define a 64bit "de" variant I suppose, but doesn't really make much sense just for this one case, and when we start to use the DSB for this stuff we'd also need another 64bit variant for that. Just easier to do 32bit always. While at it we can reorder stuff a bit so that we write the registers in order of increasing offset (more or less).

2021-12-01drm/i915/dp: Perform 30ms delay after source OUI writeLyude Paul
While working on supporting the Intel HDR backlight interface, I noticed that there's a couple of laptops that will very rarely manage to boot up without detecting Intel HDR backlight support - even though it's supported on the system. One example of such a laptop is the Lenovo P17 1st generation. Following some investigation Ville Syrjälä did through the docs they have available to them, they discovered that there's actually supposed to be a 30ms wait after writing the source OUI before we begin setting up the rest of the backlight interface. This seems to be correct, as adding this 30ms delay seems to have completely fixed the probing issues I was previously seeing. So - let's start performing a 30ms wait after writing the OUI, which we do in a manner similar to how we keep track of PPS delays (e.g. record the timestamp of the OUI write, and then wait for however many ms are left since that timestamp right before we interact with the backlight) in order to avoid waiting any longer then we need to. As well, this also avoids us performing this delay on systems where we don't end up using the HDR backlight interface.

2021-11-26drm: get rid of DRM_DEBUG_* log calls in drm core, files drm_a*.cClaudio Suarez
DRM_DEBUG_* and DRM_* log calls are deprecated. Change them to drm_dbg_* / drm_{err,info,...} calls in drm core files. To avoid making a very big patch, this change is split in smaller patches. This one includes drm_a*.c Signed-off-by: Claudio Suarez <cssk@net-c.es> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/YaC7zXW119tlzfVh@gineta.localdomain
2021-11-25drm/bridge: megachips: Ensure both bridges are probed before registrationMartyn Welch
In the configuration used by the b850v3, the STDP2690 is used to read EDID data whilst it's the STDP4028 which can detect when monitors are connected. This can result in problems at boot with monitors connected when the STDP4028 is probed first, a monitor is detected and an attempt is made to read the EDID data before the STDP2690 has probed: [

2021-11-22drm/amdgpu: partially revert "svm bo enable_signal call condition"Christian König
Partially revert commit 5f319c5c21b5909abb43d8aadc92a8aa549ee443. First of all this is illegal use of RCU to call dma_fence_enable_sw_signaling() since we don't hold a reference to the fence in question and can crash badly. Then the code doesn't seem to have the intended effect since only the exclusive fence is handled, but the KFD fences are always added as shared fence. Only keep the handling to throw away the content of SVM BOs.
