7a7a933edd drm/vmwgfx: Introduce VMware mks-guest-stats
VMware mks-guest-stats mechanism allows the collection of performance stats from
guest userland GL contexts, as well as from vmwgfx kernelspace, via a set of sw-
defined performance counters. The userspace performance counters are (de)registerd
with vmware-vmx-stats hypervisor via new iocts. The vmwgfx kernelspace counters
are controlled at build-time via a new config DRM_VMWGFX_MKSSTATS.

* Add vmw_mksstat_{add|remove|reset}_ioctl controlling the tracking of
  mks-guest-stats in guest winsys contexts
* Add DRM_VMWGFX_MKSSTATS config to drivers/gpu/drm/vmwgfx/Kconfig controlling
  the instrumentation of vmwgfx for kernelspace mks-guest-stats counters
* Instrument vmwgfx vmw_execbuf_ioctl to collect mks-guest-stats according to
  DRM_VMWGFX_MKSSTATS

d92223ead9 drm/vmwgfx: Simplify devcaps code
Make devcaps code self-contained so that it's easier to cache
and operate on them.
As the number of devcaps got bigger the code dealing with them
got more and more tricky. Lets create a central place to deal
with all the complexity. This lets us remove the lock we used
to require to deal with register write races because we only
read the devcaps at initialization.

527a947187 drm/vmwgfx: Fix return value check in vmw_setup_pci_resources()
In case of error, the function devm_ioremap() returns NULL pointer not ERR_PTR().
The IS_ERR() test in the return value check should be replaced with NULL test.
After that, the error code -ENOMEM should be returned.

523375c943 drm/vmwgfx: Port vmwgfx to arm64
This change fixes all of the arm64 issues we've had in the driver.
ARM support is provided in svga version 3, for which support we've added
in previous changes. svga version 3 currently lacks many of the
advanced features (in particular 3D support is lacking) but
that will change in time.

2cd80dbd35 drm/vmwgfx: Add basic support for SVGA3
SVGA3 is the next version of our PCI device. Some of the changes
include using MMIO for register accesses instead of ioports,
deprecating the FIFO MMIO and removing a lot of the old and
legacy functionality. SVGA3 doesn't support guest backed
objects right now so everything except 3D is working.

aec70c3912 drm/vmwgfx: replace idr_init() by idr_init_base()
idr_init() uses base 0 which is an invalid identifier for this driver.
The idr_alloc for this driver uses 1 as start value for ID range. The
new function idr_init_base allows IDR to set the ID lookup from base 1.
This avoids all lookups that otherwise starts from 0 since 0 is always
unused / available.

d4bd7776a7 drm/ttm: rework ttm_tt page limit v4
TTM implements a rather extensive accounting of allocated memory.

There are two reasons for this:
1. It tries to block userspace allocating a huge number of very small
   BOs without accounting for the kmalloced memory.

2. Make sure we don't over allocate and run into an OOM situation
   during swapout while trying to handle the memory shortage.

This is only partially a good idea. First of all it is perfectly
valid for an application to use all of system memory, limiting it to
50% is not really acceptable.

What we need to take care of is that the application is held
accountable for the memory it allocated. This is what control
mechanisms like memcg and the normal Linux page accounting already do.

Making sure that we don't run into an OOM situation while trying to
cope with a memory shortage is still a good idea, but this is also
not very well implemented since it means another opportunity of
recursion from the driver back into TTM.

So start to rework all of this by implementing a shrinker callback which
allows for TT object to be swapped out if necessary.

v2: Switch from limit to shrinker callback.
v3: fix gfp mask handling, use atomic for swapable_pages, add debugfs
v4: drop the extra gfp_mask checks

ff36baf807 drm/vmwgfx: Drop svga_lock
This isn't actually protecting anything becuase:
- when running, ttm_resource_manager->use_type is protected through
  vmw_private->reservation_semaphore against concurrent execbuf or
  well anything else that might evict or reserve buffers
- during suspend/resume there's nothing else running, hence
  vmw_pm_freeze and vmw_pm_restore do not need to take the same lock.
- this also holds for the SVGA_REG_ENABLE register write

Hence it is safe to just remove that spinlock.

8426ed9c4b drm/vmwgfx: Cleanup the cmd/fifo split
Lets try to cleanup the usage of the term FIFO which we used for
both our MMIO based cmd queue processing and for general
command processing which could have been using command buffers
interface. We're going to rename the functions which are processing
commands (and work either via MMIO or command buffers) as _cmd_
and functions which operate on the MMIO based commands as FIFO
to match the SVGA device naming.

70a59dd829 drm/<drivers>: Constify struct drm_driver
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)

7a60c2dd0f drm: Remove SCATTERLIST_MAX_SEGMENT
Since commit 9a40401cfa ("lib/scatterlist: Do not limit max_segment to
PAGE_ALIGNED values") the max_segment input to sg_alloc_table_from_pages()
does not have to be any special value. The new algorithm will always
create something less than what the user provides. Thus eliminate this
confusing constant.

- vmwgfx should use the HW capability, not mix in the OS page size for
  calling dma_set_max_seg_size()

- i915 uses i915_sg_segment_size() both for sg_alloc_table_from_pages
  and for some open coded sgl construction. This doesn't change the value
  since rounddown(size, UINT_MAX) == SCATTERLIST_MAX_SEGMENT

- drm_prime_pages_to_sg uses it as a default if max_segment is zero,
  UINT_MAX is fine to use directly.
