The __assign_str macro has an unusual ending semicolon but the vast
majority of uses of the macro already have semicolon termination.
$ git grep -P '\b__assign_str\b' | wc -l
551
$ git grep -P '\b__assign_str\b.*;' | wc -l
480
Add semicolons to the __assign_str() uses without semicolon termination
and all the other uses without semicolon termination via additional defines
that are equivalent to __assign_str() with the eventual goal of removing
the semicolon from the __assign_str() macro definition.

This patch does not change current behaviour.
The driver's job timeout handler now returns
status indicating back to the DRM layer whether
the device (GPU) is no longer available, such as
after it's been unplugged, or whether all is
normal, i.e. current behaviour.
All drivers which make use of the
drm_sched_backend_ops' .timedout_job() callback
have been accordingly renamed and return the
would've-been default value of
DRM_GPU_SCHED_STAT_NOMINAL to restart the task's
timeout timer--this is the old behaviour, and is
preserved by this patch.
v2: Use enum as the status of a driver's job
timeout callback method.
v3: Return scheduler/device information, rather
than task information.

This patch adapts the panfrost pre-defined thresholds change [0] to the
lima driver to improve real-world performance. The upthreshold value has
been set to ramp GPU frequency to max freq faster (compared to panfrost)
to compensate for the lower overall performance of utgard devices.

SHMEM-buffer backing storage is allocated from system memory; which is
typically cachable. The default mode for SHMEM objects is writecombine
though.
Unify SHMEM semantics by defaulting to cached mappings. The exception
is pages imported via dma-buf. DMA memory is usually not cached.
DRM drivers that require write-combined mappings set the map_wc flag
in struct drm_gem_shmem_object to true. This currently affects lima,
panfrost and v3d.
The drivers mgag200, udl, virtio and vkms continue to use default
shmem mappings.
The drivers cirrus and gm12u320 change caching flags. Both used
writecombine and now switch over to shmem defaults. Both drivers use
SHMEM objects as shadow buffers for internal video memory, so cached
mappings will not affect them negatively.
v3:
* set value of shmem pointer before dereferencing it in
__drm_gem_shmem_create() (Dan, kernel test robot)
v2:
* recreate patch on top of latest SHMEM helpers
* update lima, panfrost, v3d to select writecombine (Daniel, Rob)

This patch replaces the vmap/vunmap's use of raw pointers in GEM object
functions with instances of struct dma_buf_map. GEM backends are
converted as well. For most of them, this simply changes the returned type.
TTM-based drivers now return information about the location of the memory,
either system or I/O memory. GEM VRAM helpers and qxl now use ttm_bo_vmap()
et al. Amdgpu, nouveau and radeon use drm_gem_ttm_vmap() et al instead of
implementing their own vmap callbacks.
v7:
* init QXL cursor to mapped BO buffer (kernel test robot)
v5:
* update vkms after switch to shmem
v4:
* use ttm_bo_vmap(), drm_gem_ttm_vmap(), et al. (Daniel, Christian)
* fix a trailing { in drm_gem_vmap()
* remove several empty functions instead of converting them (Daniel)
* comment uses of raw pointers with a TODO (Daniel)

Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support.
Subsequent patch will address this.
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the
platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is
maybe a bit too much, hence the num_ioctls assignment prevents a
const driver structure.
- arcpgu, because that is stuck behind a pending tiny-fication series
from me.
- legacy drivers, because legacy requires non-const drm_driver.
Note that for armada I also went ahead and made the ioctl array const.
Only cc'ing the driver people who've not been converted (everyone else
is way too much).
v2: Fix one misplaced const static, should be static const (0day)
v3:
- Improve commit message (Sam)

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.
