Test: boot corsola with minigbm gralloc/mapper
Change-Id: I1f1e8a57f37e26694320c3ddee01fbad453f854b
Adds a new intel backend for interfacing with the Xe kernel driver.
Currently only tested on gen12 (Xe1; e.g. TGL, ADL, MTL).
Test 1: drm-tests (natively): stop ui and then run:
- mapped_texture_test
- null_platform_test -m [I915_FORMAT_MOD_X_TILED|I915_FORMAT_MOD_Y_TILED]
- plane_test (by default it uses NV12)
Test 2: full OS: boot to UI, execute webGL and/or YouTube successfully and watch
the terminal: TERM=xterm watch -n1 -d cat /sys/kernel/debug/dri/0/i915_display_info
for color formats and display plane usage
v1: Carlos Santa <carlos.santa@intel.corp-partner.google.com>
v2: Ryan Neph <ryanneph@google.com>
- formatting fixes
- remove deprecated #ifdef I915_SCANOUT_Y_TILED conditional compilation
- add missing backend_xe implementations
- mimic i915_add_combinations
- Match formatting, order of operations, and add the missing combo for
YVU420_ANDROID + USE_CAMERA_WRITE.
- In a future CL, we'll factor this into a common function called by both
backends.
- simplify xe_bo_map()
- The conditional body is always taken, so remove the conditional entirely.
- mark late-gen12 as mtl_or_newer until proper version handling is used.

For PCI passthrough and other use cases, it's desirable to get the
render target out of the guest. In the PCI passthrough case, the
dGPU's memory is not available to the host.
The solution that many people are interested in is to use virtgpu
to allocate, and use the dGPU to render to that guest memory. This
change adds a flag to the existing blob api, indicating to the host
that it *must* create an OS-specific handle out of guest memory upon
success.
Obviously, this is just for prototyping. Only when the lords and
princes of dri-devel/mesa-dev -- eyes filled with the light of
upstream, swords as cold as blue ice -- descend from their heavenly
abodes on top of Mount Gogigyeopbbang may we have a proper
solution.
But for now, we'll have to live in our downstream mud hut with yet
another hack. Oh well!

This change provides a route to the host side "cross domain"
allocator, which is specialized for resource sharing across domain
boundaries. It uses the upcoming CONTEXT_INIT ioctl to initialize
the backend when available, and multiple timelines to perform
metadata queries.
While it would be awesome to use the revolutionary Address Space
Graphics (ASG) algorithm for metadata queries, it would be
non-trivial to pull off in minigbm.
Key aspects of the cross-domain allocator are:
* Intelligently falls back to OpenGL texture allocation host-side
when external memory is not available. The fallback path is
named "virgl", even though it encompasses gfxstream and 2D mode.
More refactorings will be added in the future for further
clarity.
* Uses host Vulkan or minigbm to perform metadata query, and uses
a cache to minimize vmexits.
* No shadow memory. Only zero-copy blobs will be supported if the
blob is mappable. Shareable blobs may be compressed or tiled if
not mappable.
* A commitment to sharing code across Google projects and
cross-platform GPU virtualization.
The main goal here is to enable faster interation/testing, so this
code is just a prototype. It should be fine to merge via minigbm,
since the project has a very chill philosophy and even proudly
accepts code that doesn't make any sense (crrev.com/c/2583188)
[so long as existing users are not broken].
