Alyssa Rosenzweig f5585700be pan/bi: Model LD_VAR_BUF instructions
These are indirect versions of LD_VAR_BUF_IMM, taking their index in bytes. Used
for indirect varying loads (the NIR lowering is inefficient).

Alyssa Rosenzweig 3485b8dc78 pan/bi: Use consistent modifier lists in packing
If there are modifiers only used by pseudo instructions, not the real
instructions, bi_packer can get out-of-sync with bi_opcodes, causing
hard-to-debug issues. Do the stupid-simple thing to ensure this doesn't happen.

This may be a temporary issue, depending whether ISA.xml and the IR get split
out for better Valhall support.

Emma Anholt b1fa2068b8 nouveau/nir: Enable nir_opt_move/sink.
NIR load_consts/inputs tend to happen together at the top of the program.
In the TGSI backend the loads got emitted at use time, while the NIR
backend was emitting the loads at load intrinsic time.  By sinking the
intrinsics, we can greatly reduce register pressure.

declaring an actual variable and returning it in

All those MSVC/c++ related-constraints are quite annoying to be honest,
but it looks like the D3D12 headers have been updated to plain C
recently, which will allow us to write the driver in C, and hopefully
get all this sort of issues behind us.

the previous method of using affected_states to trigger constant updates
was ineffectual in the scenario where a ubo pointsize was needed on
the first time a non-precompiled shader was used after being the not-last
vertex stage:

* have vs+gs -> gs precompiles with pointsize lowering -> gs constants get updated
* remove gs -> vs was precompiled without pointsize lowering -> vs constants broken

now just do a quick check as in st_atom_shader.c and set the flag manually to
ensure the update is done correctly every time

Rob Clark 802f4da5ee freedreno/drm: Add virtio backend
Add a new backend to enable using native driver in a VM guest, via a new
virtgpu context type which (indirectly) makes host kernel interface
available in guest and handles the details of mapping buffers to guest,
etc.

Note that fence-fd's are currently a bit awkward, in that they get
signaled by the guest kernel driver (drm/virtio) once virglrenderer in
the host has processed the execbuf, not when host kernel has signaled
the submit fence.  For passing buffers to the host (virtio-wl) the egl
context in virglrenderer is used to create a fence on the host side.
But use of out-fence-fd's in guest could have slightly unexpected
results.  For this reason we limit all submitqueues to default priority
(so they cannot be preepmted by host egl context).  AFAICT virgl and
venus have a similar problem, which will eventually be solveable once we
have RESOURCE_CREATE_SYNC.

are probably more bo's that can be flagged as such.

TODO add fd_bo_upload() for memcpy to bo.. this would be useful for
uploads, for example, shaders which we just write once and never touch
again.. for virtio this could be implemented with a TRANSFER_TO_HOST
ioctl.

Rob Clark 598405c91f freedreno/drm: Rework bo creation path
Decoupling handle and fd_bo creation simplifies things for "normal" drm
drivers, avoiding duplication for the create vs import paths.  But this
is awkward for the virtio backend when wants to do multiple things in
the same guest<->host round trip.

So instead, split the paths in the interface backend and move the code
sharing for the two different paths into the msm backend itself.
