We recorded the execlists->queue_priority_hint update for the inflight request without kicking the tasklet. The next submitted request then failed to be scheduled as it had a lower priority than the hint, leaving the HW running with only the inflight request.

Make sure to select the port's AUX power domain while holding the TC port lock. The domain depends on the port's current TC mode, which may get changed under us if we're not holding the lock.

When CONFIG_DRM_I915_DEBUG_GEM is not set, clang warns: drivers/gpu/drm/i915/gvt/scheduler.c:884:1: warning: function 'check_shadow_context_ppgtt' is not needed and will not be emitted [-Wunneeded-internal-declaration] check_shadow_context_ppgtt(struct execlist_ring_context *c, struct intel_vgpu_mm *m) ^ 1 warning generated. This warning is similar to -Wunused-function but rather than warning that the function is completely unused, it warns that it is used in some expression within the file but that expression will be evaluated to a constant or be optimized away in the final assembly, essentially making it appeared used but really isn't. Usually, this happens when a function or variable is only used in sizeof, where it will appear to be used but will be evaluated at compile time and not be required to be emitted. In this case, the function is only used in GEM_BUG_ON, which is defined as BUILD_BUG_ON_INVALID, which intentionally follows this pattern. To fix this warning, add __maybe_unused to make it clear that this is intentional depending on the configuration.

Pull the code to do the CS timestamp ns<->ticks conversion into helpers and use them all over. The check in i915_perf_noa_delay_set() seems a bit dubious, so we switch it to do what I assume it wanted to do all along (ie. make sure the resulting delay in CS timestamp ticks doesn't exceed 32bits)?

According to BSpec 53998, we should try to restrict qgv points, which can't provide enough bandwidth for desired display configuration. Currently we are just comparing against all of those and take minimum(worst case). v2: Fixed wrong PCode reply mask, removed hardcoded values. v3: Forbid simultaneous legacy SAGV PCode requests and restricting qgv points. Put the actual restriction to commit function, added serialization(thanks to Ville) to prevent commit being applied out of order in case of nonblocking and/or nomodeset commits. v4: - Minor code refactoring, fixed few typos(thanks to James Ausmus) - Change the naming of qgv point masking/unmasking functions(James Ausmus). - Simplify the masking/unmasking operation itself, as we don't need to mask only single point per request(James Ausmus) - Reject and stick to highest bandwidth point if SAGV can't be enabled(BSpec) v5: - Add new mailbox reply codes, which seems to happen during boot time for TGL and indicate that QGV setting is not yet available. v6: - Increase number of supported QGV points to be in sync with BSpec. v7: - Rebased and resolved conflict to fix build failure. - Fix NUM_QGV_POINTS to 8 and moved that to header file(James Ausmus) v8: - Don't report an error if we can't restrict qgv points, as SAGV can be disabled by BIOS, which is completely legal. So don't make CI panic. Instead if we detect that there is only 1 QGV point accessible just analyze if we can fit the required bandwidth requirements, but no need in restricting. v9: - Fix wrong QGV transition if we have 0 planes and no SAGV simultaneously. v10: - Fix CDCLK corruption, because of global state getting serialized without modeset, which caused copying of non-calculated cdclk to be copied to dev_priv(thanks to Ville for the hint). v11: - Remove unneeded headers and spaces(Matthew Roper) - Remove unneeded intel_qgv_info qi struct from bw check and zero out the needed one(Matthew Roper) - Changed QGV error message to have more clear meaning(Matthew Roper) - Use state->modeset_set instead of any_ms(Matthew Roper) - Moved NUM_SAGV_POINTS from i915_reg.h to i915_drv.h where it's used - Keep using crtc_state->hw.active instead of .enable(Matthew Roper) - Moved unrelated changes to other patch(using latency as parameter for plane wm calculation, moved to SAGV refactoring patch) v12: - Fix rebase conflict with own temporary SAGV/QGV fix. - Remove unnecessary mask being zero check when unmasking qgv points as this is completely legal(Matt Roper) - Check if we are setting the same mask as already being set in hardware to prevent error from PCode. - Fix error message when restricting/unrestricting qgv points to "mask/unmask" which sounds more accurate(Matt Roper) - Move sagv status setting to icl_get_bw_info from atomic check as this should be calculated only once.(Matt Roper) - Edited comments for the case when we can't enable SAGV and use only 1 QGV point with highest bandwidth to be more understandable.(Matt Roper) v13: - Moved max_data_rate in bw check to closer scope(Ville Syrjälä) - Changed comment for zero new_mask in qgv points masking function to better reflect reality(Ville Syrjälä) - Simplified bit mask operation in qgv points masking function (Ville Syrjälä) - Moved intel_qgv_points_mask closer to gen11 SAGV disabling, however this still can't be under modeset condition(Ville Syrjälä) - Packed qgv_points_mask as u8 and moved closer to pipe_sagv_mask (Ville Syrjälä) - Extracted PCode changes to separate patch.(Ville Syrjälä) - Now treat num_planes 0 same as 1 to avoid confusion and returning max_bw as 0, which would prevent choosing QGV point having max bandwidth in case if SAGV is not allowed, as per BSpec(Ville Syrjälä) - Do the actual qgv_points_mask swap in the same place as all other global state parts like cdclk are swapped. In the next patch, this all will be moved to bw state as global state, once new global state patch series from Ville lands v14: - Now using global state to serialize access to qgv points - Added global state locking back, otherwise we seem to read bw state in a wrong way. v15: - Added TODO comment for near atomic global state locking in bw code. v16: - Fixed intel_atomic_bw_* functions to be intel_bw_* as discussed with Jani Nikula. - Take bw_state_changed flag into use. v17: - Moved qgv point related manipulations next to SAGV code, as those are semantically related(Ville Syrjälä) - Renamed those into intel_sagv_(pre)|(post)_plane_update (Ville Syrjälä) v18: - Move sagv related calls from commit tail into intel_sagv_(pre)|(post)_plane_update(Ville Syrjälä) v19: - Use intel_atomic_get_bw_(old)|(new)_state which is intended for commit tail stage. v20: - Return max bandwidth for 0 planes(Ville) - Constify old_bw_state in bw_atomic_check(Ville) - Removed some debugs(Ville) - Added data rate to debug print when no QGV points(Ville) - Removed some comments(Ville) v21, v22, v23: - Fixed rebase conflict v24: - Changed PCode mask to use ICL_ prefix v25: - Resolved rebase conflict v26: - Removed redundant NULL checks(Ville) - Removed redundant error prints(Ville) v27: - Use device specific drm_err(Ville) - Fixed parenthesis ident reported by checkpatch Line over 100 warns to be fixed together with existing code style.

In order to use a common VSC SDP Colorimetry calculating code on PSR, it uses a new psr vsc sdp compute routine.

Compared to implementation of DP and HDMI's encoder->infoframes_enabled, the lspcon's implementation returns its active state. (we expect enabled infoframe states of HW.) It leads to pipe state mismatch error when ddi_get_config is called. Because the current implementation of lspcon is not ready to support readout infoframes, we need to return 0 here. In order to support readout to lspcon, we need to implement read_infoframe and infoframes_enabled. And set_infoframes also have to set an appropriate bit on crtc_state->infoframes.enable Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

In order to use computed config for DP SDPs (DP VSC SDP and DP HDR Metadata Infoframe SDP), it replaces intel_dp_vsc_enable() function and intel_dp_hdr_metadata_enable() function to intel_dp_set_infoframes() function. And it removes unused functions. Before: intel_dp_vsc_enable() and intel_dp_hdr_metadata_enable() compute sdp configs and program sdp registers on enable callback of encoder. After: It separates computing of sdp configs and programming of sdp register. The compute config callback of encoder calls computing sdp configs. The enable callback of encoder calls programming sdp register. v3: Rebased v5: Polish commit message [Uma] v10: Rebased Signed-off-by:

It adds an unpack only function for DRM infoframe for dynamic range and mastering infoframe readout. It unpacks the information data block contained in the binary buffer into a structured frame of the HDMI Dynamic Range and Mastering (DRM) information frame. In contrast to hdmi_drm_infoframe_unpack() function, it does not verify a checksum. It can be used for unpacking a DP HDR Metadata Infoframe SDP case. DP HDR Metadata Infoframe SDP uses the same Dynamic Range and Mastering (DRM) information (CTA-861-G spec.) such as HDMI DRM infoframe. But DP SDP header and payload structure are different from HDMI DRM Infoframe. Therefore unpacking DRM infoframe for DP requires skipping of a verifying checksum. v9: Add clear comments to hdmi_drm_infoframe_unpack_only() and hdmi_drm_infoframe_unpack() (Laurent Pinchart) Signed-off-by: -

The second try at staging the transfer of the breadcrumb. In part one, we realised we could not simply move to the second engine as we were only holding the breadcrumb lock on the first. So in commit 6c81e21a ("drm/i915/gt: Stage the transfer of the virtual breadcrumb"), we removed it from the first engine and marked up this request to reattach the signaling on the new engine. However, this failed to take into account that we only attach the breadcrumb if the new request is added at the start of the queue, which if we are transferring, it is because we know there to be a request to be signaled (and hence we would not be attached). In this attempt, we try to transfer the completed requests to the irq_worker on its rq->engine->breadcrumbs. This preserves the coupling between the rq and its breadcrumbs, so that i915_request_cancel_breadcrumb() does not attempt to manipulate the list under the wrong lock. v2: Code sharing is fun.

By providing the default values configured into the kernel via sysfs, it is much more convenient for userspace to restore those sane defaults, or at least know what are considered good baseline.

Now that we have fast timeslicing on semaphores, we no longer need to prioritise none-semaphore work as we will yield any work blocked on a semaphore to the next in the queue. Previously with no timeslicing, blocking on the semaphore caused extremely bad scheduling with multiple clients utilising multiple rings. Now, there is no impact and we can remove the complication.

The initial-breadcrumb is used to mark the end of the awaiting and the beginning of the user payload. We verify that we do not start the user payload before all signaler are completed, checking our semaphore setup by looking for the initial breadcrumb being written too early. We also want to ensure that we do not add semaphore waits after we have already closed the semaphore section, an issue for later deferred waits. Signed-off-by:

It is possible for a residual tasklet to be pending execution as we resume (whether that's some prior test kicking off the tasklet, or if we are in a suspend/resume stress test). As such, we do not want that tasklet to execute in the middle of our sanitization, such that it sees the poisoned state.

Seems that only skl needs to have SAGV turned off for multipipe scenarios, so lets do it this way. If anything blows up - we can always revert this patch. v2: Changed if condition to look better (Ville). Signed-off-by:

Introduce platform dependent SAGV checking in combination with bandwidth state pipe SAGV mask. This is preparation to adding TGL support, which requires different way of SAGV checking. v2, v3, v4, v5, v6: Fix rebase conflict v7: - Nuke icl specific function, use skl for icl as well, gen specific active_pipes check to be added in the next patch(Ville) v8: - Use more generic intel_crtc_can_enable_sagv for checking(Ville) Signed-off-by: -

For future Gen12 SAGV implementation we need to seemlessly alter wm levels calculated, depending on whether we are allowed to enable SAGV or not. So this accessor will give additional flexibility to do that. Currently this accessor is still simply working as "pass-through" function. This will be changed in next coming patches from this series. v2: - plane_id -> plane->id(Ville Syrjälä) - Moved wm_level var to have more local scope (Ville Syrjälä) - Renamed yuv to color_plane(Ville Syrjälä) in skl_plane_wm_level v3: - plane->id -> plane_id(this time for real, Ville Syrjälä) - Changed colorplane id type from boolean to int as index (Ville Syrjälä) - Moved crtc_state param so that it is first now (Ville Syrjälä) - Moved wm_level declaration to tigher scope in skl_write_plane_wm(Ville Syrjälä) v4: - Started to use enum values for color plane - Do sizeof for a type what we are memset'ing - Zero out wm_uv as well(Ville Syrjälä) v5: - Fixed rebase conflict caused by COLOR_PLANE_* enum removal v6: - Do not use skl_plane_wm_level accessor in skl_allocate_pipe_ddb v7: - Get rid of wm_uv, which is not used in skl_plane_write_wm(Ville) Signed-off-by:
