2021-02-05Revert "drm/qxl: do not run release if qxl failed to init"Gerd Hoffmann1-2/+0
This reverts commit b91907a6241193465ca92e357adf16822242296d. Patch is broken, it effectively makes qxl_drm_release() a nop because on normal driver shutdown qxl_drm_release() is called *after* drm_dev_unregister().

2021-01-29drm/scheduler: Job timeout handler returns status (v3)Luben Tuikov7-28/+52
This patch does not change current behaviour. The driver's job timeout handler now returns status indicating back to the DRM layer whether the device (GPU) is no longer available, such as after it's been unplugged, or whether all is normal, i.e. current behaviour. All drivers which make use of the drm_sched_backend_ops' .timedout_job() callback have been accordingly renamed and return the would've-been default value of DRM_GPU_SCHED_STAT_NOMINAL to restart the task's timeout timer--this is the old behaviour, and is preserved by this patch. v2: Use enum as the status of a driver's job timeout callback method. v3: Return scheduler/device information, rather than task information.

2021-01-28drm/vc4: hdmi: Restore cec physical address on reconnectDom Cobley1-6/+18
Currently we call cec_phys_addr_invalidate on a hotplug deassert. That may be due to a TV power cycling, or an AVR being switched on (and switching edid). This makes CEC unusable since our controller wouldn't have a physical address anymore. Set it back up again on the hotplug assert.

The code prior to 311e305fdb4e ("drm/vc4: hdmi: Implement a register layout abstraction") was relying on the fact that the register offset was incremented by 4 for each readl call. That worked since the register width is 4 bytes. However, since that commit the HDMI_READ macro is now taking an enum, and the offset doesn't increment by 4 but 1 now. Divide the index by 4 to fix this.

Additional compatible strings have been added in DT source for the i.MX6SL, i.MX6SLL, i.MX6UL and i.MX7D without updating the bindings. Most of the upstream DT sources use the fsl,imx28-lcdif compatible string, which mostly predates the realization that the LCDIF in the i.MX6 and newer SoCs have extra features compared to the i.MX28. Update the bindings to add the missing compatible strings, with the correct fallback values. This fails to validate some of the upstream DT sources.

2021-01-22drm/drm_vblank: set the dma-fence timestamp during send_vblank_eventVeera Sundaram Sankaran3-13/+67
The explicit out-fences in crtc are signaled as part of vblank event, indicating all framebuffers present on the Atomic Commit request are scanned out on the screen. Though the fence signal and the vblank event notification happens at the same time, triggered by the same hardware vsync event, the timestamp set in both are different. With drivers supporting precise vblank timestamp the difference between the two timestamps would be even higher. This might have an impact on use-mode frameworks using these fence timestamps for purposes other than simple buffer usage. For instance, the Android framework [1] uses the retire-fences as an alternative to vblank when frame-updates are in progress. Set the fence timestamp during send vblank event using a new drm_send_event_timestamp_locked variant to avoid discrepancies.

Some drivers have hardware capability to get the precise HW timestamp of certain events based on which the fences are triggered. The delta between the event HW timestamp & current HW reference timestamp can be used to calculate the timestamp in kernel's CLOCK_MONOTONIC time domain. This allows it to set accurate timestamp factoring out any software and IRQ latencies. Add a timestamp variant of fence signal function, dma_fence_signal_timestamp to allow drivers to update the precise timestamp for fences.

We were not correctly unpinning no longer needed buffers. In particular vmw_buffer_object, which is internally often pinned on creation wasn't unpinned on destruction and none of the internal MOB buffers were unpinned before being put back. Technically this existed for a long time but commit 57fcd550eb15 ("drm/ttm: Warn on pinning without holding a reference") introduced a WARN_ON which was filling up the kernel logs rather quickly. Quite frankly internal usage of vmw_buffer_object and in general pinning needs to be refactored in vmwgfx but for now this makes it work.
