It can be calculated according to the kernel source code as:
(ring->max_dw - emit_frame_size) / emit_ib_size

If vertex does not complete a primitive, it should not set the odd
flag which miss lead liveness check when culling is enabled.
For example, if odd flag is set regardless of complete flag, when
culling is enabled, 3 vertices of a triangle's init prim flag:
[0x00 0x04 0x01]
then after culling, this triangle has been culled, their prim flag:
[0x00 0x04 0x00]
the second vertex is miss treat as live because its odd flag (code
check prim_flag!=0 for liveness).

Instead of using a SALU instruction to add to the scalar
offset, rely on the buffer swizzling and use constant offset.

Update the metadata format. For gfx8- chips nothing change.
For gfx9 chips:
* for textures without a valid modifier a dw is added at index=10
containing the stride
* for textures with a valid modifier the modifier is stored at
index 10 and 11. Then the number of planes is stored at 12.
Then for each plane the offset and the stride are stored.
The goal here is to be able to create textures from dmabuf from
umr - without these changes this is impossible because these
values can't be guessed.
The new layout is compatible with version=1 so old/new UMD can
be used together without issues and isn't used by default.
For radeonsi, it will be possible to use it with a AMD_DEBUG=...
option.

radeonsi uses ac_nir_optimize_outputs to eliminate output stores with
identical SSA defs (i.e. duplicated), which then causes 2 outputs to
map to the same parameter export.
This is a regression. The old LLVM code was correctly emitting each
export only once. vs_output_param_mask was supposed to be used for
this instead of vs_output_param_offset.

Radeonsi is going to use nir tess factor write, so need to

RADV set tess factor driver location to be 0 and 1 in
get_linked_variable_location(). While radeonsi also set them
to be 0 and 1 in st->map_io aka. si_shader_io_get_unique_index_patch().
We could just set them to be 0 and 1 at the beginning of
ac_nir_lower_hs_outputs_to_mem(), but in order to keep the
location map at the same place, we still do this in
lower_hs_output_store().
