2022-02-11drm/amdgpu: skipping SDMA hw_init and hw_fini for S0ix.Rajib Mahapatra1-0/+8
[Why] SDMA ring buffer test failed if suspend is aborted during S0i3 resume. [How] If suspend is aborted for some reason during S0i3 resume cycle, it follows SDMA ring test failing and errors in amdgpu resume. For RN/CZN/Picasso, SMU saves and restores SDMA registers during S0ix cycle. So, skipping SDMA suspend and resume from driver solves the issue. This time, the system is able to resume gracefully even the suspend is aborted.

2022-02-11drm/i915: Clean up the bigjoiner state copy logicVille Syrjälä3-75/+108
Currently the bigjoiner state copy logic is kind of a byzantine mess. Clean it up to operate in the following manner during a full modeset: 1) master uapi -> hw state copy 2) master hw -> slave hw state copy And during a non-modeset update we do: 1) master uapi -> hw state light copy 2) master hw -> slave hw state light copy I think that is now easier to reason about since we never do any kind of master uapi -> slave hw state copy short circuit that could happen previously. Obviously this does now depend on the master uapi->hw copy always happening before the master hw -> slave hw copy, but that is guaranteed by the fact that we always add both crtcs to the state early, the crtcs are registered in pipe order (so the compute_config loop happens in pipe order), and the hardware requires the master pipe has to be lower than the slave pipe as well. And for good measure we shall add a check+WARN for this before doing the bigjoiner crtc assignment. v2: Fix uapi.ctm vs. hw.ctm copy-paste fail Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220204072049.1610-1-ville.syrjala@linux.intel.com Reviewed-by: Manasi Navare <manasi.d.navare@intel.com>
2022-02-11drm/i915: Remove weird code from intel_atomic_check_bigjoiner()Ville Syrjälä1-22/+11
There's some weird junk in intel_atomic_check_bigjoiner() that's trying to look at the old crtc state's bigjoiner usage for some reason. That code is totally unnecessary, and maybe even actively harmful. Not entirely sure which since it's such a mess that I can't actually wrap my brain around what it ends up doing. Either way, thanks to intel_bigjoiner_add_affected_crtcs() all of the old bigjoiner crtcs are guaranteed to be in the state already if any one of them is in the state. Also if any one of those crtcs got flagged for a modeset, then all of them will have been flagged, and the bigjoiner links will have been detached via kill_bigjoiner_slave(). So there is no need to look examing any old bigjoiner usage in intel_atomic_check_bigjoiner(). All we have to care about is whether bigjoiner is needed for the new state, and whether we can get the slave crtc we need.

We seem to be missing a few things from the bigjoiner state copy. Namely hw.mode isn't getting copied (which probably causes PIPESRC to be misconfigured), CTM/LUTs aren't getting copied (which could cause the pipe to produced incorrect output), and we also forgot to copy over the color_mgmt_changed flag so potentially we fail to do the actual CTM/LUT programming (assuming we aren't doing a full modeset or fastset).

2022-02-11drm/cma-helper: Set VM_DONTEXPAND for mmapRobin Murphy1-0/+1
drm_gem_cma_mmap() cannot assume every implementation of dma_mmap_wc() will end up calling remap_pfn_range() (which happens to set the relevant vma flag, among others), so in order to make sure expectations around VM_DONTEXPAND are met, let it explicitly set the flag like most other GEM mmap implementations do. This avoids repeated warnings on a small minority of systems where the display is behind an IOMMU, and has a simple driver which does not override drm_gem_cma_default_funcs. Arm hdlcd is an in-tree affected driver. Out-of-tree, the Apple DCP driver is affected; this fix is required for DCP to be mainlined.

2022-02-11drm/panfrost: Handle IDVS_GROUP_SIZE featureAlyssa Rosenzweig3-0/+7
The IDVS group size feature was missing. It is used on some Bifrost and Valhall GPUs, and is the last kernel-relevant Bifrost feature we're missing. This feature adds an extra IDVS group size field to the JM_CONFIG register. In kbase, the value is configurable via the device tree; kbase uses 0xF as a default if no value is specified. Until we find a device demanding otherwise, let's always set the 0xF default on devices which support this feature mimicking kbase's behaviour. Tuning this register slightly improves performance of index-driven vertex shading. On Mali-G52 (with Mesa), overall glmark2 score is improved from 1026 to 1037. Geometry-heavy scenes like -bshading are improved from 1068 to 1098.

2022-02-11drm/i915/selftests: Disable runtime pm wakeref tracking for the mock deviceVille Syrjälä3-0/+6
commit c50df701d49e ("drm/i915: Enable rpm wakeref tracking whether runtime pm is enabled or not") enabled wakeref tracking even for the mock device. Turns out that has somewhat significant overhead, and on the glacial Core m3's we have in CI the vma selftests are now exceeding the allotted time budget. So let's disable the wakeref tracking once again for the mock device in order to avoid blowing up the selftest runtime.

2022-02-11drm/i915/mst: update slot information for 128b/132bJani Nikula1-2/+31
128b/132b supports using 64 slots starting from 0, while 8b/10b reserves slot 0 for metadata. Commit d6c6a76f80a1 ("drm: Update MST First Link Slot Information Based on Encoding Format") added support for updating the topology state accordingly, and commit 41724ea273cd ("drm/amd/display: Add DP 2.0 MST DM Support") started using it in the amd driver. This feels more than a little cumbersome, especially updating the information in atomic check. For i915, add the update to MST connector .compute_config hook rather than iterating over all MST managers and connectors in global mode config .atomic_check. Fingers crossed. v3: - Propagate errors from intel_dp_mst_update_slots() (Ville) v2: - Update in .compute_config() not .atomic_check (Ville) Cc: Bhawanpreet Lakha <Bhawanpreet.Lakha@amd.com> Cc: Lyude Paul <lyude@redhat.com> Cc: Uma Shankar <uma.shankar@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Acked-by: Lyude Paul <lyude@redhat.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220208152317.3019070-1-jani.nikula@intel.com

2022-02-11drm/i915/dp: rewrite DP 2.0 128b/132b link training based on errataJani Nikula1-1/+300
The DP 2.0 errata completely overhauls the 128b/132b link training, with no provisions for backward compatibility with the original DP 2.0 specification. The changes are too intrusive to consider reusing the same code for both 8b/10b and 128b/132b, mainly because the LTTPR channel equalisation is done concurrently instead of serialized. NOTES: * It's a bit unclear when to wait for DP_INTERLANE_ALIGN_DONE and per-lane DP_LANE_SYMBOL_LOCKED. Figure xx4 in the SCR implies the LANEx_CHANNEL_EQ_DONE sequence may end with either 0x77,0x77,0x85 *or* 0x33,0x33,0x84 (for four lane configuration in DPCD 0x202..0x204) i.e. without the above bits set. Text elsewhere seems contradictory or incomplete. * We read entire link status (6 bytes) everywhere instead of individual DPCD addresses. * There are some subtle ambiguities or contradictions in the order of some DPCD access and TPS signal enables/disables. It's also not clear whether these are significant. v4: - Wait for intra-hop clear after link training end (Ville) - Wait instead of single check for intra-hop clear before link train v3: - Use msecs_to_jiffies_timeout() (Ville) - Read status at the beginning of interlane align done loop (Ville) - Try to simplify timeout flag use where possible (Ville) v2: - Always try one last time after timeouts to avoid races (Ville) - Extend timeout to cover the entire LANEx_EQ_DONE sequence (Ville) - Also check for eq interlane align done in LANEx_CDS_DONE Sequence (Ville) - Check for Intra-hop status before link training Cc: Uma Shankar <uma.shankar@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220208143209.2997337-1-jani.nikula@intel.com
