There's some interactions between the SCDC setup and the disconnection / reconnection of displays. Let's document it and a solution. Reviewed-by:

Maxime Ripard authored
During a hotplug cycle (such as a TV going out of suspend, or when the cable is disconnected and reconnected), the expectation is that the same state used before the disconnection is reused until the next commit. However, the HDMI scrambling requires that some flags are set in the monitor, and those flags are very likely to be reset when the cable has been disconnected. This will thus result in a blank display, even if the display pipeline configuration hasn't been modified or is in the exact same state. The solution we've had so far is to enable the scrambling-related bits again on reconnection, but the HDMI 2.0 specification (Section 6.1.3.1 - Scrambling Control) requires that the scrambling enable bit is set before sending any scrambled video signal. Using that solution thus breaks that expectation. The solution used by i915 is to do a full modeset on the connector so that we disable the video signal, enable the scrambling bit, and enable the video signal again. As such, we took that code and plugged it into vc4. It probably could have been turned into an helper, but it proved to be difficult for several reasons: * i915 has fairly different structures than simpler KMS drivers such as vc4, so doing some code that works with both proved to be difficult; * Other simpler drivers could reuse some of it (tegra, dw-hdmi), but it would still require to move some parameters currently stored in private structure that are needed to compute whether the scrambling is needed or not, and then inform the driver that it needs to be enabled. Some of those parameters are already in core structures (drm_display_mode, drm_display_info, bpc), but the output format isnt't. Adding it is fairly challenging since unlike the TMDS char rate or mode, there's no consensus on what format to pick in drivers, so it's not possible to write some generic code that can depend on it. For these reasons, we chose to duplicate the code for now, until someone else really needs it as well, in which case we will be able to convert it into a generic helper. Reviewed-by: -

We'll need the locking context in future patch, so let's convert .detect to .detect_ctx. Reviewed-by:

Maxime Ripard authored
Our detect callback has a bunch of operations to perform depending on the current and last status of the connector, such a setting the CEC physical address or enabling the scrambling again. This is currently dealt with a bunch of if / else statetements that make it fairly difficult to read and extend. Let's move all that logic to a function of its own. Reviewed-by:

Maxime Ripard authored
We recently introduced a new mutex to protect concurrent execution of ALSA and KMS hooks, and the concurrent access to some of vc4_hdmi fields. However, using it in the detect hook was creating a reentrency issue with CEC code. Indeed, calling cec_s_phys_addr_from_edid from detect might call the CEC adap_enable hook with the lock held, eventually resulting in a deadlock. Since we didn't really need to protect anything at the moment in the CEC code, the decision was made to ignore the mutex in those CEC hooks, working around the issue. However, we can have the same thing happening if we end up triggering a mode set from the detect callback, for example using drm_atomic_helper_connector_hdmi_reset_link(). Since we don't really need to protect anything in detect either, let's just drop the lock in detect, and add it again in CEC. Reviewed-by:

Even though vc4_hdmi_supports_scrambling takes a mode as an argument, it never uses it. Let's remove it. Reviewed-by:

drm_plane_state->src might be modified by the driver. This is done e.g. in i915 driver when there is bigger framebuffer than the plane and there is some offset within framebuffer. I915 driver calculates separate offset and adjusts src rect coords to be relative to this offset. Damage clips are still relative to original src coords provided by user-space. This patch ensures original coordinates provided by user-space are used when initiliazing damage iterator. Signed-off-by:

Merge tag 'drm-intel-gt-next-2022-09-09' of git://anongit.freedesktop.org/drm/drm-intel into drm-next UAPI Changes: - Revert "drm/i915/dg2: Add preemption changes for Wa_14015141709" The intent of Wa_14015141709 was to inform us that userspace can no longer control object-level preemption as it has on past platforms (i.e., by twiddling register bit CS_CHICKEN1[0]). The description of the workaround in the spec wasn't terribly well-written, and when we requested clarification from the hardware teams we were told that on the kernel side we should also probably stop setting FF_SLICE_CS_CHICKEN1[14], which is the register bit that directs the hardware to honor the settings in per-context register CS_CHICKEN1. It turns out that this guidance about FF_SLICE_CS_CHICKEN1[14] was a mistake; even though CS_CHICKEN1[0] is non-operational and useless to userspace, there are other bits in the register that do still work and might need to be adjusted by userspace in the future (e.g., to implement other workarounds that show up). If we don't set FF_SLICE_CS_CHICKEN1[14] in i915, then those future workarounds would not take effect.

It's better to perform the sync at the very last of the suspend instead of the pipe-disable function, so that we can catch all pending URBs (if any). While we're at it, drop the error code from udl_sync_pending_urb() since we basically ignore it; instead, give a clear error message indicating a problem. Acked-by:

udl_alloc_urb_list() retires the allocation if there is no enough room left, and it reinitializes the stuff unnecessarily such as the linked list head and the waitqueue, which could be harmful. Those should be outside the retry loop. Acked-by:

Takashi Iwai authored
In the current design, udl_get_urb() may be called asynchronously during the driver freeing its URL list via udl_free_urb_list(). The problem is that the sync is determined by comparing the urbs.count and urbs.available fields, while we clear urbs.count field only once after udl_free_urb_list() finishes, i.e. during udl_free_urb_list(), the state becomes inconsistent. For fixing this inconsistency and also for hardening the locking scheme, this patch does a slight refactoring of the code around udl_get_urb() and udl_free_urb_list(). Now urbs.count is updated in the same spinlock at extracting a URB from the list in udl_free_url_list(). Acked-by:
