2020-05-14drm/i915/dp: Add compute routine for DP PSR VSC SDPGwan-gyeong Mun2-2/+72
In order to use a common VSC SDP Colorimetry calculating code on PSR, it adds a compute routine for PSR VSC SDP. As PSR routine can not use infoframes.vsc of crtc state, it also adds new writing of DP SDPs (Secondary Data Packet) for PSR. PSR routine has its own scenario and timings of writing a VSC SDP. v3: Replace a structure name to drm_dp_vsc_sdp from intel_dp_vsc_sdp v4: Use struct drm_device logging macros v10: 1) Fix packing of VSC SDP where Pixel Encoding/Colorimetry Format is not supported. 2) Change a checking of PSR state.

2020-05-14drm/i915: Fix enabled infoframe states of lspconGwan-gyeong Mun1-1/+1
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 <[email protected]> Signed-off-by: Gwan-gyeong Mun <[email protected]> Reviewed-by: Uma Shankar <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2020-05-14drm/i915: Program DP SDPs with computed configsGwan-gyeong Mun3-237/+1
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: Gwan-gyeong Mun <[email protected]> Reviewed-by: Uma Shankar <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2020-05-14drm/i915/gt: Transfer old virtual breadcrumbs to irq_workerChris Wilson4-34/+57
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 6c81e21a4742 ("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.

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.

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.

i915_gem_evict_something() is charged with finding a slot within the GTT that we may reuse. Since our goal is not to stall, we first look for a slot that only overlaps idle vma. To this end, on the first pass we move any active vma to the end of the search list. However, we only stopped moving active vma after we see the first active vma twice. If during the search, that first active vma completed, we would not notice and keep on extending the search list.

2020-05-11drm/i915: Mark concurrent submissions with a weak-dependencyChris Wilson5-6/+15
We recorded the dependencies for WAIT_FOR_SUBMIT in order that we could correctly perform priority inheritance from the parallel branches to the common trunk. However, for the purpose of timeslicing and reset handling, the dependency is weak -- as we the pair of requests are allowed to run in parallel and not in strict succession. The real significance though is that this allows us to rearrange groups of WAIT_FOR_SUBMIT linked requests along the single engine, and so can resolve user level inter-batch scheduling dependencies from user semaphores.
