[Why] The HW interrupt gets disabled after S3/S4/reset so we don't receive notifications for HPD or AUX from DMUB - leading to timeout and black screen with (or without) DPIA links connected. [How] Re-enable the interrupt after S3/S4/reset like we do for the other DC interrupts. Guard both instances of the outbox interrupt enable or we'll hang during restore on ASIC that don't support it.

While working on supporting the Intel HDR backlight interface, I noticed that there's a couple of laptops that will very rarely manage to boot up without detecting Intel HDR backlight support - even though it's supported on the system. One example of such a laptop is the Lenovo P17 1st generation. Following some investigation Ville Syrjälä did through the docs they have available to them, they discovered that there's actually supposed to be a 30ms wait after writing the source OUI before we begin setting up the rest of the backlight interface. This seems to be correct, as adding this 30ms delay seems to have completely fixed the probing issues I was previously seeing. So - let's start performing a 30ms wait after writing the OUI, which we do in a manner similar to how we keep track of PPS delays (e.g. record the timestamp of the OUI write, and then wait for however many ms are left since that timestamp right before we interact with the backlight) in order to avoid waiting any longer then we need to. As well, this also avoids us performing this delay on systems where we don't end up using the HDR backlight interface.

For previous version, it uses 'sg_table.nent's to traverse sg_table in pages free flow. However, 'sg_table.nents' is reassigned in 'dma_map_sg', it means the number of created entries in the DMA adderess space. So, use 'sg_table.nents' in pages free flow will case some pages can't be freed. Here we should use sg_table.orig_nents to free pages memory, but use the sgtable helper 'for each_sgtable_sg'(, instead of the previous rather common helper 'for_each_sg' which maybe cause memory leak) is much better.

This simply adds proper support for panel backlights that can be controlled via VESA's backlight control protocol, but which also require that we enable and disable the backlight via PWM instead of via the DPCD interface. We also enable this by default, in order to fix some people's backlights that were broken by not having this enabled. For reference, backlights that require this and use VESA's backlight interface tend to be laptops with hybrid GPUs, but this very well may change in the future. v4: * Make sure that we call intel_backlight_level_to_pwm() in intel_dp_aux_vesa_enable_backlight() - vsyrjala Signed-off-by:

Our current code is supposed to serialise the commits by waiting for all the drm_crtc_commits associated to the previous HVS state. However, assuming we have two CRTCs running and being configured and we configure each one alternately, we end up in a situation where we're not waiting at all. Indeed, starting with a state (state 0) where both CRTCs are running, and doing a commit (state 1) on the first CRTC (CRTC 0), we'll associate its commit to its assigned FIFO in vc4_hvs_state. If we get a new commit (state 2), this time affecting the second CRTC (CRTC 1), the DRM core will allow both commits to execute in parallel (assuming they don't have any share resources). Our code in vc4_atomic_commit_tail is supposed to make sure we only get one commit at a time and serialised by order of submission. It does so by using for_each_old_crtc_in_state, making sure that the CRTC has a FIFO assigned, is used, and has a commit pending. If it does, then we'll wait for the commit before going forward. During the transition from state 0 to state 1, as our old CRTC state we get the CRTC 0 state 0, its commit, we wait for it, everything works fine. During the transition from state 1 to state 2 though, the use of for_each_old_crtc_in_state is wrong. Indeed, while the code assumes it's returning the state of the CRTC in the old state (so CRTC 0 state 1), it actually returns the old state of the CRTC affected by the current commit, so CRTC 0 state 0 since it wasn't part of state 1. Due to this, if we alternate between the configuration of CRTC 0 and CRTC 1, we never actually wait for anything since we should be waiting on the other every time, but it never is affected by the previous commit. Change the logic to, at every commit, look at every FIFO in the previous HVS state, and if it's in use and has a commit associated to it, wait for that commit.

Our HVS global state, when duplicated, will also copy the pointer to the drm_crtc_commit (and increase the reference count) for each FIFO if the pointer is not NULL. However, our atomic_setup function will overwrite that pointer without putting the reference back leading to a memory leak. Since the commit is only relevant during the atomic commit process, it doesn't make sense to duplicate the reference to the commit anyway. Let's remove it.

Commit 9ec03d7f ("drm/vc4: kms: Wait on previous FIFO users before a commit") introduced a wait on the previous commit done on a given HVS FIFO. However, we never cleared that pointer once done. Since drm_crtc_commit_put can free the drm_crtc_commit structure directly if we were the last user, this means that it can lead to a use-after free if we were to duplicate the state, and that stale pointer would even be copied to the new state. Set the pointer to NULL once we're done with the wait so that we don't carry over a pointer to a free'd structure.

Commit 9ec03d7f ("drm/vc4: kms: Wait on previous FIFO users before a commit") introduced a global state for the HVS, with each FIFO storing the current CRTC commit so that we can properly synchronize commits. However, the refcounting was off and we thus ended up leaking the drm_crtc_commit structure every commit. Add a drm_crtc_commit_put to prevent the leakage.

Maxime Ripard authored
Several DRM/KMS atomic commits can run in parallel if they affect different CRTC. These commits share the global HVS state, so we have some code to make sure we run commits in sequence. This synchronization code is one of the first thing that runs in vc4_atomic_commit_tail(). Another constraints we have is that we need to make sure the HVS clock gets a boost during the commit. That code relies on clk_set_min_rate and will remove the old minimum and set a new one. We also need another, temporary, minimum for the duration of the commit. The algorithm is thus to set a temporary minimum, drop the previous one, do the commit, and finally set the minimum for the current mode. However, the part that sets the temporary minimum and drops the older one runs before the commit synchronization code. Thus, under the proper conditions, we can end up mixing up the minimums and ending up with the wrong one for our current step. To avoid it, let's move the clock setup in the protected section.

The current virtgpu implementation of poll(..) drops events when VIRTGPU_CONTEXT_PARAM_POLL_RINGS_MASK is enabled (otherwise it's like a normal DRM driver). This is because paravirtualized userspaces receives responses in a buffer of type BLOB_MEM_GUEST, not by read(..). To be in line with other DRM drivers and avoid specialized behavior, it is possible to define a dummy event for virtgpu. Paravirtualized userspace will now have to call read(..) on the DRM fd to receive the dummy event. Fixes: b1079043 ("drm/virtgpu api: create context init feature") Reported-by:
