drm/v3d: Replace wait_for macros to remove use of msleep

2020-03-05T06:15:34+00:00

The wait_for macro's for Broadcom V3D driver used msleep, which is
inappropriate due to its inaccuracy at low values (minimum wait time
is about 30ms on the Raspberry Pi).  This sleep was triggering in
v3d_clean_caches(), causing us to only be able to dispatch ~33 compute
jobs per second.

This patch replaces the macro with the one from the Intel i915 version
which uses usleep_range to provide more accurate waits.

v2: Split from the vc4 patch so that we can confidently apply to
    stable (by anholt)

drm/scheduler: rework entity creation

2019-12-18T21:09:12+00:00

Entity currently keeps a copy of run_queue list and modify it in
drm_sched_entity_set_priority(). Entities shouldn't modify run_queue
list. Use drm_gpu_scheduler list instead of drm_sched_rq list
in drm_sched_entity struct. In this way we can select a runqueue based
on entity/ctx's priority for a  drm scheduler.

Merge v5.4-rc7 into drm-next

We have the i915 security fixes to backmerge, but first
let's clear the decks for other drivers to avoid a bigger
mess.

drm/v3d: Fix memory leak in v3d_submit_cl_ioctl

2019-10-23T18:57:05+00:00

In the impelementation of v3d_submit_cl_ioctl() there are two memory
leaks. One is when allocation for bin fails, and the other is when bin
initialization fails. If kcalloc fails to allocate memory for bin then
render->base should be put. Also, if v3d_job_init() fails to initialize
bin->base then allocated memory for bin should be released.

drm/v3d: clean caches at the end of render jobs on request from user space

2019-09-19T19:57:44+00:00

Extends the user space ioctl for CL submissions so it can include a request
to flush the cache once the CL execution has completed. Fixes memory
write violation messages reported by the kernel in workloads involving
shader memory writes (SSBOs, shader images, scratch, etc) which sometimes
also lead to GPU resets during Piglit and CTS workloads.

v2: if v3d_job_init() fails we need to kfree() the job instead of
    v3d_job_put() it (Eric Anholt).

v3 (Eric Anholt):
  - Drop _FLAG suffix from the new flag name.
  - Add a new param so userspace can tell whether cache flushing is
    implemented in the kernel.
