2020-10-30drm/nouveau/kms/nv50-: Fix clock checking algorithm in nv50_dp_mode_valid()Lyude Paul
While I thought I had this correct (since it actually did reject modes like I expected during testing), Ville Syrjala from Intel pointed out that the logic here isn't correct. max_clock refers to the max data rate supported by the DP encoder. So, limiting it to the output of ds_clock (which refers to the maximum dotclock of the downstream DP device) doesn't make any sense. Additionally, since we're using the connector's bpc as the canonical BPC we should use this in mode_valid until we support dynamically setting the bpp based on bandwidth constraints. https://lists.freedesktop.org/archives/dri-devel/2020-September/280276.html For more info. So, let's rewrite this using Ville's advice. v2: * Ville pointed out I mixed up the dotclock and the link rate. So fix that... * ...and also rename all the variables in this function to be more appropriately labeled so I stop mixing them up. * Reuse the bpp from the connector for now until we have dynamic bpp selection. * Use use DIV_ROUND_UP for calculating the mode rate like i915 does, which we should also have been doing from the start Signed-off-by: Lyude Paul <lyude@redhat.com> Fixes: 409d38139b42 ("drm/nouveau/kms/nv50-: Use downstream DP clock limits for mode validation") Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Lyude Paul <lyude@redhat.com> Cc: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2020-10-30drm/nouveau/kms/nv50-: Program notifier offset before requesting disp capsLyude Paul
Not entirely sure why this never came up when I originally tested this (maybe some BIOSes already have this setup?) but the ->caps_init vfunc appears to cause the display engine to throw an exception on driver init, at least on my ThinkPad P72: nouveau 0000:01:00.0: disp: chid 0 mthd 008c data 00000000 0000508c 0000102b This is magic nvidia speak for "You need to have the DMA notifier offset programmed before you can call NV507D_GET_CAPABILITIES." So, let's fix this by doing that, and also perform an update afterwards to prevent racing with the GPU when reading capabilities. v2: * Don't just program the DMA notifier offset, make sure to actually perform an update v3: * Don't call UPDATE() * Actually read the correct notifier fields, as apparently the CAPABILITIES_DONE field lives in a different location than the main NV_DISP_CORE_NOTIFIER_1 field.

2020-10-29drm/i915: Restore ILK-M RPS supportVille Syrjälä
Restore RPS for ILK-M. We lost it when an extra HAS_RPS() check appeared in intel_rps_enable(). Unfortunaltey this just makes the performance worse on my ILK because intel_ips insists on limiting the GPU freq to the minimum. If we don't do the RPS init then intel_ips will not limit the frequency for whatever reason. Either it can't get at some required information and thus makes wrong decisions, or we mess up some weights/etc. and cause it to make the wrong decisions when RPS init has been done, or the entire thing is just wrong. Would require a bunch of reverse engineering to figure out what's going on.

2020-10-29drm/i915/region: fix max size calculationMatthew Auld
We are incorrectly limiting the max allocation size as per the mm max_order, which is effectively the largest power-of-two that we can fit in the region size. However, it's normal to setup the region or allocator with a non-power-of-two size(for example 3G), which we should already handle correctly, except it seems for the early too-big-check. v2: make sure we also exercise the I915_BO_ALLOC_CONTIGUOUS path, which is quite different, since for that we are actually limited by the largest power-of-two that we can fit within the region size.

2020-10-29drm/vc4: Rework the structure conversion functionsMaxime Ripard
Most of the helpers to retrieve vc4 structures from the DRM base structures rely on the fact that the first member of the vc4 structure is the DRM one and just cast the pointers between them. However, this is pretty fragile especially since there's no check to make sure that the DRM structure is indeed at the offset 0 in the structure, so let's use container_of to make it more robust.

2020-10-28drm/shme-helpers: Fix dma_buf_mmap forwarding bugDaniel Vetter
When we forward an mmap to the dma_buf exporter, they get to own everything. Unfortunately drm_gem_mmap_obj() overwrote vma->vm_private_data after the driver callback, wreaking the exporter complete. This was noticed because vb2_common_vm_close blew up on mali gpu with panfrost after commit 26d3ac3cb04d ("drm/shmem-helpers: Redirect mmap for imported dma-buf"). Unfortunately drm_gem_mmap_obj also acquires a surplus reference that we need to drop in shmem helpers, which is a bit of a mislayer situation. Maybe the entire dma_buf_mmap forwarding should be pulled into core gem code. Note that the only two other drivers which forward mmap in their own code (etnaviv and exynos) get this somewhat right by overwriting the gem mmap code. But they seem to still have the leak. This might be a good excuse to move these drivers over to shmem helpers completely.

2020-10-27drm/vc4: hdmi: Avoid sleeping in atomic contextMaxime Ripard
When running the trigger hook, ALSA by default will take a spinlock, and thus will run the trigger hook in atomic context. However, our HDMI driver will send the infoframes as part of the trigger hook, and part of that process is to wait for a bit to be cleared for up to 100ms. To be nicer to the system, that wait has some usleep_range that interact poorly with the atomic context. There's several ways we can fix this, but the more obvious one is to make ALSA take a mutex instead by setting the nonatomic flag on the DAI link. That doesn't work though, since now the cyclic callback installed by the dmaengine helpers in ALSA will take a mutex, while that callback is run by dmaengine's virt-chan code in a tasklet where sleeping is not allowed either. Given the delay we need to poll the bit for, changing the usleep_range for a udelay and keep running it from a context where interrupts are disabled is not really a good option either. However, we can move the infoframe setup code in the hw_params hook, like is usually done in other HDMI controllers, that isn't protected by a spinlock and thus where we can sleep. Infoframes will be sent on a regular basis anyway, and since hw_params is where the audio parameters that end up in the infoframes are setup, this also makes a bit more sense.

2020-10-26drm/sun4i: frontend: Reuse the ch0 phase for RGB formatsMaxime Ripard
When using the scaler on the A10-like frontend with single-planar formats, the current code will setup the channel 0 filter (used for the R or Y component) with a different phase parameter than the channel 1 filter (used for the G/B or U/V components). This creates a bleed out that keeps repeating on of the last line of the RGB plane across the rest of the display. The Allwinner BSP either applies the same phase parameter over both channels or use a separate one, the condition being whether the input format is YUV420 or not. Since YUV420 is both subsampled and multi-planar, and since YUYV is subsampled but single-planar, we can rule out the subsampling and assume that the condition is actually whether the format is single or multi-planar. And it looks like applying the same phase parameter over both channels for single-planar formats fixes our issue, while we keep the multi-planar formats working properly.

2020-10-26drm/sun4i: frontend: Rework a bit the phase dataMaxime Ripard
The scaler filter phase setup in the allwinner kernel has two different cases for setting up the scaler filter, the first one using different phase parameters for the two channels, and the second one reusing the first channel parameters on the second channel. The allwinner kernel has a third option where the horizontal phase of the second channel will be set to a different value than the vertical one (and seems like it's the same value than one used on the first channel). However, that code path seems to never be taken, so we can ignore it for now, and it's essentially what we're doing so far as well. Since we will have always the same values across each components of the filter setup for a given channel, we can simplify a bit our frontend structure by only storing the phase value we want to apply to a given channel.
