This line appears to confuse the compiler and had been noticed previously in clang-tidy output. There isn't anything fundamentally wrong that I can see. I suspect that it just looks like a mistake - hence the first note.

drm_bridge_hpd_enable()/drm_bridge_hpd_disable() callbacks call into the respective driver's hpd_enable()/hpd_disable() ops. These ops control the HPD enable/disable logic which in some cases like MSM can be a dedicate hardware block to control the HPD. During probe_defer cases, a connector can be initialized and then later destroyed till the probe is retried. During connector destroy in these cases, the hpd_disable() callback gets called without a corresponding hpd_enable() leading to an unbalanced state potentially causing even a crash. This can be avoided by the respective drivers maintaining their own state logic to ensure that a hpd_disable() without a corresponding hpd_enable() just returns without doing anything. However, to have a generic fix it would be better to avoid the hpd_disable() callback from the connector destroy path and let the hpd_enable() / hpd_disable() balance be maintained by the corresponding drm_bridge_connector_enable_hpd() / drm_bridge_connector_disable_hpd() APIs which should get called by drm_kms_helper_disable_hpd(). changes in v2: - minor change in commit text (Dmitry) Signed-off-by:

While making the changes in [1], it was noted that the documentation of the enable_hpd() and disable_hpd() does not make it clear that these ops should not try to do hpd state maintenance and should only enable/disable hpd related hardware for the connector. The state management of these calls to make sure these calls are balanced is handled by the DRM core and we should keep it that way to minimize the overhead in the drivers which implement these ops.

Loosen the requirements for atomic and legacy commit so that, in cases where pixel_source != FB, the commit can still go through. This includes adding framebuffer NULL checks in other areas to account for FB being NULL when non-FB pixel sources are enabled. To disable a plane, the pixel_source must be NONE or the FB must be NULL if pixel_source == FB. Signed-off-by:

Add support for pixel_source property to drm_plane and related documentation. In addition, force pixel_source to DRM_PLANE_PIXEL_SOURCE_FB in DRM_IOCTL_MODE_SETPLANE as to not break legacy userspace. This enum property will allow user to specify a pixel source for the plane. Possible pixel sources will be defined in the drm_plane_pixel_source enum. Currently, the only pixel sources are DRM_PLANE_PIXEL_SOURCE_FB (the default value) and DRM_PLANE_PIXEL_SOURCE_NONE. Acked-by:

This consists of simply storing the most recent deadline, and adding an ioctl to retrieve the deadline. This can be used in conjunction with the SET_DEADLINE ioctl on a fence fd for testing. Ie. create various sw_sync fences, merge them into a fence-array, set deadline on the fence-array and confirm that it is propagated properly to each fence. v2: Switch UABI to express deadline as u64 v3: More verbose UAPI docs, show how to convert from timespec v4: Better comments, track the soonest deadline, as a normal fence implementation would, return an error if no deadline set.

Add a new flag to let userspace provide a deadline as a hint for syncobj and timeline waits. This gives a hint to the driver signaling the backing fences about how soon userspace needs it to compete work, so it can adjust GPU frequency accordingly.

Currently the QAIC DRM device registers itself when the MHI QAIC_CONTROL channel becomes available. This is when the device is able to process workloads. However, the DRM driver also provides the debugfs interface bootlog for the device. If the device fails to boot to the QSM (which brings up the MHI QAIC_CONTROL channel), the bootlog won't be available for debugging why it failed to boot. Change when the DRM device registers itself from when QAIC_CONTROL is available to when the card is first probed on the PCI bus. Additionally, make the DRM driver persist through reset/error cases so the driver doesn't have to be reloaded to access the card again. Send KOBJ_ONLINE/OFFLINE uevents so userspace can know when DRM device is ready to handle requests. Signed-off-by:

A CPU job is a type of job that performs operations that requires CPU intervention. A copy performance query job is a job that copy the complete or partial result of a query to a buffer. In order to copy the result of a performance query to a buffer, we need to get the values from the performance monitors. So, create a user extension for the CPU job that enables the creation of a copy performance query job. This user extension will allow the creation of a CPU job that copy the results of a performance query to a BO with the possibility to indicate the availability with a availability bit. Signed-off-by:

A CPU job is a type of job that performs operations that requires CPU intervention. An indirect CSD job is a job that, when executed in the queue, will map the indirect buffer, read the dispatch parameters, and submit a regular dispatch. Therefore, it is a job that needs CPU intervention. So, create a user extension for the CPU job that enables the creation of an indirect CSD. This user extension will allow the creation of a CSD job linked to a CPU job. The CPU job will wait for the indirect CSD job dependencies and, once they are signaled, it will update the CSD job parameters. Co-developed-by:

Currently, v3d_get_extensions() only parses multisync data and assigns it to the `struct v3d_submit_ext`. But, to implement the CPU job with user extensions, we want v3d_get_extensions() to be able to parse CPU job data and assign it to the `struct v3d_cpu_job`. Therefore, allow the function v3d_get_extensions() to use `struct v3d_cpu_job *` as a parameter. If the `struct v3d_cpu_job *` is assigned to NULL, it means that the job is a GPU job and CPU job extensions should be rejected. Signed-off-by:

Create a new type of job, a CPU job. A CPU job is a type of job that performs operations that requires CPU intervention. The overall idea is to use user extensions to enable different types of CPU job, allowing the CPU job to perform different operations according to the type of user extension. The user extension ID identify the type of CPU job that must be dealt. Having a CPU job is interesting for synchronization purposes as a CPU job has a queue like any other V3D job and can be synchoronized by the multisync extension. Signed-off-by:

We want to allow the IOCTLs to allocate the job without initiating it. This will be useful for the CPU job submission IOCTL, as the CPU job has the need to use information from the user extensions. Currently, the user extensions are parsed before the job allocation, making it impossible to fill the CPU job when parsing the user extensions. Therefore, decouple the job allocation from the job initiation. Signed-off-by:

At the moment the driver does not use DRM_PLANE_COMMIT_ACTIVE_ONLY, but still checks for crtc->state->active in tidss_crtc_atomic_flush(), and skips the flush if the crtc is not active. The exact reason why DRM_PLANE_COMMIT_ACTIVE_ONLY is not used has been lost in history. DRM_PLANE_COMMIT_ACTIVE_ONLY does also affect the plane updates, and I think the issue was related to multi-display systems and moving planes between the displays. However, it is possible the issue was only present on the older DSS hardware, handled by the omapdrm driver (on which the tidss driver is loosely based). Reviewing the code related to DRM_PLANE_COMMIT_ACTIVE_ONLY does not show any issues, and testing on J7 EVM with two displays works fine. Change the driver to use DRM_PLANE_COMMIT_ACTIVE_ONLY.
