2020-07-02drm/atomic-helper: reset vblank on crtc resetDaniel Vetter
Only when vblanks are supported ofc. Some drivers do this already, but most unfortunately missed it. This opens up bugs after driver load, before the crtc is enabled for the first time. syzbot spotted this when loading vkms as a secondary output. Given how many drivers are buggy it's best to solve this once and for all in shared helper code. Aside from moving the few existing calls to drm_crtc_vblank_reset into helpers (i915 doesn't use helpers, so keeps its own) I think the regression risk is minimal: atomic helpers already rely on drivers calling drm_crtc_vblank_on/off correctly in their hooks when they support vblanks. And driver that's failing to handle vblanks after this is missing those calls already, and vblanks could only work by accident when enabling a CRTC for the first time right after boot. Big thanks to Tetsuo for helping track down what's going wrong here. There's only a few drivers which already had the necessary call and needed some updating: - komeda, atmel and tidss also needed to be changed to call __drm_atomic_helper_crtc_reset() intead of open coding it - tegra and msm even had it in the same place already, just code motion, and malidp already uses __drm_atomic_helper_crtc_reset(). - Laurent noticed that rcar-du and omap open-code their crtc reset and hence would actually be broken by this patch now. So fix them up by reusing the helpers, which brings the drm_crtc_vblank_reset() back. Only call left is in i915, which doesn't use drm_mode_config_reset, but has its own fastboot infrastructure. So that's the only case where we actually want this in the driver still. I've also reviewed all other drivers which set up vblank support with drm_vblank_init. After the previous patch fixing mxsfb all atomic drivers do call drm_crtc_vblank_on/off as they should, the remaining drivers are either legacy kms or legacy dri1 drivers, so not affected by this change to atomic helpers. v2: Use the drm_dev_has_vblank() helper. v3: Laurent pointed out that omap and rcar-du used drm_crtc_vblank_off instead of drm_crtc_vblank_reset. Adjust them too. v4: Laurent noticed that rcar-du and omap open-code their crtc reset and hence would actually be broken by this patch now. So fix them up by reusing the helpers, which brings the drm_crtc_vblank_reset() back. v5: also mention rcar-du and ompadrm in the proper commit message above (Laurent).

2020-07-02drm/amd/display: Only revalidate bandwidth on medium and fast updatesNicholas Kazlauskas
[Why] Changes that are fast don't require updating DLG parameters making this call unnecessary. Considering this is an expensive call it should not be done on every flip. DML touches clocks, p-state support, DLG params and a few other DC internal flags and these aren't expected during fast. A hang has been reported with this change when called on every flip which suggests that modifying these fields is not recommended behavior on fast updates. [How] Guard the validation to only happen if update type isn't FAST.

Update PROCESS_QUANTUM, the time the hardware scheduler allows processes to run before switching to other processes when it becomes over-subscribed. Increase this to 10ms, to allow processes to better amortize their task switch times. Update HQD Quantum, the amount of time that an active queue stays attached to the CP before we forcibly switch it for another active queue for fairness. Setting these so that HQD < PROCESS makes it easier to ensure that we get fairness when we have multiple active queues on the device. Otherwise we may start process-swapping before we get to all the queues in a CP.

There was probably a misunderstand on how the dma-fence-chain is supposed to work or what dma_fence_chain_find_seqno() is supposed to return. dma_fence_chain_find_seqno() is here to give us the fence to wait upon for a particular point in the timeline. The timeline progresses only when all the points prior to a given number have completed.

2020-07-02Revert "dma-buf: Report signaled links inside dma-fence-chain"Lionel Landwerlin
This reverts commit 5de376bb434f80a13138f0ebedc8351ab73d8b0d. This change breaks synchronization of a timeline. dma_fence_chain_find_seqno() might be a bit of a confusing name but this function is not trying to find a particular seqno, is supposed to give a fence to wait on for a particular point in the timeline. In a timeline, a particular value is reached when all the points up to and including that value have signaled.

2020-07-02drm/i915: Drop vm.ref for duplicate vma on constructionChris Wilson
As we allow for parallel threads to create the same vma instance concurrently, and we only filter out the duplicates upon reacquiring the spinlock for the rbtree, we have to free the loser of the constructors' race. When freeing, we should also drop any resource references acquired for the redundant vma.

2020-07-02drm/i915/gt: Move the heartbeat into the high priority system wqChris Wilson
As we ensure that the heartbeat is reasonably fast (and should not block), move the heartbeat work into the system_highpri_wq to avoid having this essential task be blocked behind other slow work, such as our own retire_work_handler.

2020-07-02drm/i915/gt: Harden the heartbeat against a stuck driverChris Wilson
If the driver gets stuck holding the kernel timeline, we cannot issue a heartbeat and so fail to discover that the driver is indeed stuck and do not issue a GPU reset (which would hopefully unstick the driver!). Switch to using a trylock so that we can query if the heartbeat's timeline mutex is locked elsewhere, and then use the timer to probe if it remains stuck at the same spot for consecutive heartbeats, indicating that the mutex has not been released and the engine has not progressed.
