this has a lot of caveats:
* extension must be supported
* resource must have usage bit set
* resource must not have any pending batch usage
* resource must be in supported layout
if all of these conditionals pass, then HIC can be used for direct image subdata

Most drivers will want nir_opt_barrier_modes() to optimize out
unnecessary memory barrier modes. However, virgl has to translate
back to GLSL, which means it can really only handle partial memory
barriers in compute shaders today, because there isn't a proper
way to express them otherwise. Just ask nir_to_tgsi to promote
these back to full barriers as a workaround.
See KHR-GL43.shader_storage_buffer_object.advanced-readWrite-case1
on virpipe-on-gl as a case where this hack is needed.

this is the inverted version of rewrite_read_as_0 which tests for mismatched
component i/o on a given location and rewrites the inputs to zero if the
producer shader didn't write to the component

Instead of failing the copy we can use multiple chunks.
This codepath shouldn't really be used since the source
image should usually be tiled but it still better to not
fail when possible.

previously non-separable progs had their libs owned exclusively by
the shaders, which meant it was possible for a background compile job
to crash while the context was being destroyed when accessing libs
which no longer had active shaders

In future patches, we will be creating a separate companion RCS engine
and each engine is created with it's own address space, and we really
don't want. CCS and RCS engine writes should be visible to each other in
order to get the wait/signal mechanism working.

The condition
!param->type->is_vector() || !param->type->is_scalar()
alawys evaluates to true:
* type is not scalar or vector -> true
* type is vector, i.e. num_components > 1 -> num_components == 1 is
false and !is_scalar() == true
* type is scalar, i.e. num_components == 1 -> num_components > 1 is
false and !is_vector() == true
There is no comment explaining why such code has been written, therefore
this seems to be a mistake.
To maintain consistency with the surrounding code,
glsl_type_is_scalar_or_vector has been used instead of
replacing || with &&.

to avoid splitting renderpasses, this subdata optimization handles the usual
driver dance of staging buffer -> gpu copy
if the pbo stride doesn't match the image format's stride, however, then
a direct copy will yield broken pixels and the image will misrender. to avoid this,
detect stride mismatch and translate the single subdata call into a sequence
of non-overlapping subdata calls that the driver can magically figure out
while continuing to not split renderpasses
