The V3D driver currently determines the GPU tech version (33, 41...)
by reading a register. This approach has worked so far since this
information wasn’t needed before powering on the GPU.
V3D 7.1 introduces new registers that must be written to power on the
GPU, requiring us to know the V3D versi
V3D 7.1 exposes a new register block, called V3D_SMS. As BCM2712 has a
V3D 7.1 core, add a new register item to the list. Similar to the GCA
and bridge register, SMS is optional and should only be added for V3D
7.1 variants.
In order to enforce per-SoC register rules, add per-compatible
restrictio
The V3D driver still relies on `drm_sched_increase_karma()` and
`drm_sched_resubmit_jobs()` for resubmissions when a timeout occurs.
The function `drm_sched_increase_karma()` marks the job as guilty, while
`drm_sched_resubmit_jobs()` sets an error (-ECANCELED) in the DMA fence of
that guilty job.
Similar to commit e4b5ccd392b9 ("drm/v3d: Ensure job pointer is set to
NULL after job completion"), ensure the job pointer is set to `NULL` when
a job's fence has an error. Failing to do so can trigger kernel warnings
in specific scenarios, such as:
