Async worker is gone. All jobs and memory allocations done in IOCTL to
align with dma fencing rules.
Async vs. sync now means when do bind operations complete relative to
the IOCTL. Async completes when out-syncs signal while sync completes
when the IOCTL returns. In-syncs and out-syncs are only allowed in async
mode.
If memory allocations fail in the job creation step the VM is killed.
This is temporary, eventually a proper unwind will be done and VM will
be usable.

There really is no difference between 'struct drm_xe_ext_vm_set_property'

specify a <property, value> pair. Replace the two extensions with a single
common 'struct drm_xe_ext_set_property' extension. The rationale is that
rather than have each XE module (including future modules) invent their own
property/value extensions, all XE modules use a common set_property

Mostly the same as i915. We add a new hint for userspace to force an
object into the mappable part of vram.
We also need to tell userspace how large the mappable part is. In Vulkan
for example, there will be two vram heaps for small-bar systems. And
here the size of each heap needs to be known. Likewise the used/avail
tracking needs to account for the mappable part.
We also limit the available tracking going forward, such that we limit
to privileged users only, since these values are system wide and are
technically considered an info leak.
v2 (Maarten):
- s/NEEDS_CPU_ACCESS/NEEDS_VISIBLE_VRAM/ in the uapi. We also no
longer require smem as an extra placement. This is more flexible,
and lets us use this for clear-color surfaces, since we need CPU access
there but we don't want to attach smem, since that effectively disables
CCS from kernel pov.
- Reject clear-color CCS buffers where NEEDS_VISIBLE_VRAM is not set,
instead of migrating it behind the scenes.
v3 (José):
- Split the changes that limit the accounting for perfmon_capable()
into a separate patch.
- Use XE_BO_CREATE_VRAM_MASK.
v4 (Gwan-gyeong Mun):
- Add some kernel-doc for the query bits.
v5:
- One small kernel-doc correction. The cpu_visible_size and
corresponding used tracking are always zero for non
XE_MEM_REGION_CLASS_VRAM.
v6:
- Without perfmon_capable() it likely makes more sense to report as
zero, instead of reporting as used == total size. This should give
similar behaviour as i915 which rather tracks free instead of used.
- Only enforce NEEDS_VISIBLE_VRAM on rc_ccs_cc_plane surfaces when the
device is actually small-bar.

Using jiffies as a timeout from userspace is weird even if
theoretically exists possiblity of acquiring jiffies via getconf.
Unfortunately this method is unreliable and the returned
value may vary from the one configured in the kernel config.
Now timeout is expressed in nanoseconds and its interpretation depends
on setting DRM_XE_UFENCE_WAIT_ABSTIME flag. Relative timeout (flag
is not set) means fence expire at now() + timeout. Absolute timeout
(flag is set) means that the fence expires at exact point of time.
Passing negative timeout means we will wait "forever" by setting
wait time to MAX_SCHEDULE_TIMEOUT.

Xe, is a new driver for Intel GPUs that supports both integrated and
discrete platforms starting with Tiger Lake (first Intel Xe Architecture).
The code is at a stage where it is already functional and has experimental
support for multiple platforms starting from Tiger Lake, with initial
support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan
drivers), as well as in NEO (for OpenCL and Level0).
The new Xe driver leverages a lot from i915.
As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there. But it is not added
in this patch.
This initial work is a collaboration of many people and unfortunately
the big squashed patch won't fully honor the proper credits. But let's
get some git quick stats so we can at least try to preserve some of the
credits:
