KIQ doesn't really use the GPU scheduler.  The base
drivers generally use the KIQ ring directly rather than
submitting IBs.  However, amdgpu_sched_hw_submission
(which defaults to 2) limits the number of outstanding
fences to 2.  KFD uses the KIQ for TLB flushes and the
2 fence limit hurts performance when there are several KFD
processes running.

v2: move some expressions to one line
    change KIQ sched_hw_submission to at least 16
v3: bump to 256

platform, where other hardware is reported to work fine with MSI.

Both tests were conducted with NV4x hardware, so perhaps other (or even

with config=NvMSI=1 on load.

(Ben): Was unable to mmiotrace the binary driver for unknown reasons,
       so not able to 100% confirm that no other changes from GP107
       are needed.  Quick testing shows it seems to work well enough
       for display.  Due to NVIDIA dragging their heels on getting
       signed firmware to us, this is the best we can do for now.

imx-drm: lock scanout transfers for consecutive bursts

- Lock the IDMAC scanout channel for multiple back-to-back bursts if possible,
  to improve memory bandwidth utilisation.
- Replace a few occurences of state->fb with the already existing local fb
  variable in ipu_plane_atomic_update

  drm/imx: ipuv3-plane: use fb local variable instead of state->fb

Final pile of features for 4.14

- New ioctl to change NOA configurations, plus prep (Lionel)
- CCS (color compression) scanout support, based on the fancy new
  modifier additions (Ville&Ben)
- Document i915 register macro style (Jani)
- Many more gen10/cnl patches (Rodrigo, Pualo, ...)
- More gpu reset vs. modeset duct-tape to restore the old way.
- prep work for cnl: hpd_pin reorg (Rodrigo), support for more power
  wells (Imre), i2c pin reorg (Anusha)
- drm_syncobj support (Jason Ekstrand)
- forcewake vs gpu reset fix (Chris)
- execbuf speedup for the no-relocs fastpath, anv/vk low-overhead ftw (Chris)
- switch to idr/radixtree instead of the resizing ht for execbuf id->vma
  lookups (Chris)

gvt:
- MMIO save/restore optimization (Changbin)
- Split workload scan vs. dispatch for more parallel exec (Ping)
- vGPU full 48bit ppgtt support (Joonas, Tina)
- vGPU hw id expose for perf (Zhenyu)

Bunch of work all over to make the igt CI runs more complete/stable.
Watch https://intel-gfx-ci.01.org/tree/drm-tip/shards-all.html for
progress in getting this ready. Next week we're going into production
mode (i.e. will send results to intel-gfx) on hsw, more platforms to

drm/tegra: Changes for v4.14-rc1

This contains a couple of fixes and improvements for host1x, with some
preparatory work for Tegra186 support.

The remainder is cleanup and minor bugfixes for Tegra DRM along with
enhancements to debuggability.

There have also been some enhancements to the kernel interfaces for
host1x job submissions and support for mmap'ing PRIME buffers directly,
all of which get the interfaces very close to ready for serious work.

  gpu: host1x: Support sub-devices recursively

  ...

this cycle has been fairly calm in etnaviv land with most of the action
happening on the userspace side.

Notable changes:
- Improvements to CONFIG option handling to make it harder for users to
shoot themselves in the foot due to kernel misconfiguration.
- Tweaked GEM object population, so that userspace can take considerate
action when memory allocation fails, rather than waking the raging OOM
killer beast.
