|  | The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function
returns the number of the created entries in the DMA address space.
However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and
dma_unmap_sg must be called with the original number of the entries
passed to the dma_map_sg().
struct sg_table is a common structure used for describing a non-contiguous
memory buffer, used commonly in the DRM and graphics subsystems. It
consists of a scatterlist with memory pages and DMA addresses (sgl entry),
as well as the number of scatterlist entries: CPU pages (orig_nents entry)
and DMA mapped pages (nents entry).
It turned out that it was a common mistake to misuse nents and orig_nents
entries, calling DMA-mapping functions with a wrong number of entries or
ignoring the number of mapped entries returned by the dma_map_sg()
function.
To avoid such issues, lets use a common dma-mapping wrappers operating
directly on the struct sg_table objects and use scatterlist page
iterators where possible. This, almost always, hides references to the
nents and orig_nents entries, making the code robust, easier to follow
and copy/paste safe.

|  | PP bcast is marked as doing async reset after job is done.
When resume after suspend, each PP is reset individually,
so no need to reset in PP bcast resume. But I forgot to
clear the PP bcast async reset mark so call into async wait
before job run and gets timeout.

|  | Most platforms with a Mali-400 or Mali-450 GPU also have support for
changing the GPU clock frequency. Add devfreq support so the GPU clock
rate is updated based on the actual GPU usage when the
"operating-points-v2" property is present in the board.dts.
The actual devfreq code is taken from panfrost_devfreq.c and modified so
it matches what the lima hardware needs:
- a call to dev_pm_opp_set_clkname() during initialization because there
  are two clocks on Mali-4x0 IPs. "core" is the one that actually clocks
  the GPU so we need to control it using devfreq.
- locking when reading or writing the devfreq statistics because (unlike
  than panfrost) we have multiple PP and GP IRQs which may finish jobs
  concurrently.

node.
From the driver POV there is no distinction between primary and render
nodes, thus we can drop the token.

There is no point to print deferred probe messages as errors.  Adjust
the printks for error paths of obtaining clocks and reset controller.
This removes the error message of lima_clk_init() call in favor or
specific failure messages inside.

|  | There is no point to print deferred probe (and its failures to get
resources) as an error.  For example getting a regulator causes three
unneeded error messages:
    lima 13000000.gpu: failed to get regulator: -517
    lima 13000000.gpu: regulator init fail -517
    lima 13000000.gpu: Fatal error during GPU init
Also do not print clock rates before the initialization finishes
because they will be duplicated after deferral.  Each probe step already
prints error so remove the final error message "Fatal error during GPU
init".
In case of multiple probe tries this would pollute the dmesg.

|  | After "5918045c4ed4 drm/scheduler: rework job destruction", lima started
to leak memory due to buffers not being destroyed after job execution in
the drm scheduler.
This started happening because the drm scheduler only destroyed buffers
after cancelling the job timeout handler, and for lima this handler was
never started as lima specified a MAX_SCHEDULE_TIMEOUT timeout.
Lima seems to run well in its current state with a real timeout, so to
make it more aligned with the other drivers from now on, let's use a
real default timeout.
This also fixes the observed memory leaks.
The 500ms value was chosen as it is the current value for all other
embedded gpu drivers using drm sched.

|  | We now destroy finished jobs from the worker thread to make sure that
we never destroy a job currently in timeout processing.
By this we avoid holding lock around ring mirror list in drm_sched_stop
which should solve a deadlock reported by a user.
v2: Remove unused variable.
v4: Move guilty job free into sched code.
v5:
Move sched->hw_rq_count to drm_sched_start to account for counter
decrement in drm_sched_stop even when we don't call resubmit jobs
if guily job did signal.
v6: remove unused variable
