Currently it66121_probe returns -EPROBE_DEFER if the there is no remote endpoint found in the device tree which doesn't seem helpful, since this is not going to change later and it is never checked if the next bridge has been initialized yet. It will fail in that case later while doing drm_bridge_attach for the next bridge in it66121_bridge_attach. Since the bindings documentation for it66121 bridge driver states there has to be a remote endpoint defined, its safe to return -EINVAL in that case. This additonally adds a check, if the remote endpoint is enabled and returns -EPROBE_DEFER, if the remote bridge hasn't been initialized (yet).

In a cl submission, when bin job initialization fails, sched job resources were already allocated for the render job. At this point, drm_sched_job_init(render) was done in v3d_job_init but the render job is aborted before drm_sched_job_arm (in v3d_job_push) happens; therefore, not only v3d_job_put but also drm_sched_job_cleanup should be called (by v3d_job_cleanup). A similar issue is addressed for csd and tfu submissions. The issue was noticed from a review by Iago Toral in a patch that touches the same part of the code.

It turns out that when locking a region, the region must be a naturally aligned power of 2. The upshot of this is that if the desired region crosses a 'large boundary' the region size must be increased significantly to ensure that the locked region completely covers the desired region. Previous calculations (including in kbase for the proprietary driver) failed to take this into account. Since it's known that the lock region must be naturally aligned we can compute the required size by looking at the highest bit position which changes between the start/end of the lock region (subtracting 1 from the end because the end address is exclusive). The start address is then aligned based on the size (this is technically unnecessary as the hardware will ignore these bits, but the spec advises to do this "to avoid confusion").

When kmem_cache_zalloc in virtio_gpu_get_vbuf fails, it will return an error code. But none of its callers checks this error code, and a core dump will take place. Considering many of its callers can't handle such error, I add a __GFP_NOFAIL flag when calling kmem_cache_zalloc to make sure it won't fail, and delete those unused error handlings.

issue: in cleanup_job the cancle_delayed_work will cancel a TO timer even the its corresponding job is still running. fix: do not cancel the timer in cleanup_job, instead do the cancelling only when the heading job is signaled, and if there is a "next" job we start_timeout again. v2: further cleanup the logic, and do the TDR timer cancelling if the signaled job is the last one in its scheduler. v3: change the issue description remove the cancel_delayed_work in the begining of the cleanup_job recover the implement of drm_sched_job_begin. v4: remove the kthread_should_park() checking in cleanup_job routine, we should cleanup the signaled job asap TODO: 1)introduce pause/resume scheduler in job_timeout to serial the handling of scheduler and job_timeout. 2)drop the bad job's del and insert in scheduler due to above serialization (no race issue anymore with the serialization) Tested-by: jingwen <jingwen.chen@@amd.com> Signed-off-by: Monk Liu <Monk.Liu@amd.com> Signed-off-by: Andrey Grodzovsky <andrey.grodzovsky@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/1630457207-13107-1-git-send-email-Monk.Liu@amd.com

Current (and older) Simics models for the Bochs VGA used the wrong PCI vendor ID (0x4321 instead of 0x1234). Although this can hopefully be fixed in the future, it is a problem for users of the current version, not the least because to update the device ID the BIOS has to be rebuilt in order to see BIOS output.

Display drivers so far need to have a lot of boilerplate to first retrieve either the panel or bridge that they are connected to using drm_of_find_panel_or_bridge(), and then either deal with each with ad-hoc functions or create a drm panel bridge through drm_panel_bridge_add. In order to reduce the boilerplate and hopefully create a path of least resistance towards using the DRM panel bridge layer, let's create the function devm_drm_of_get_bridge() to reduce that boilerplate.

To pick the change in: 7957d93b ("block: add ioctl to read the disk sequence number") It adds a new ioctl, but we are still not using that to generate tables for 'perf trace', so no changes in tooling.

Some distributions, like debian, don't link perf with libbfd. Add a build flag to make this configuration buildable and testable.
