svga: Map vertex- index- and constant buffers ansynchronously when reading

With SWTNL and index translation we're mapping buffers for reading. These
buffers are commonly upload_mgr buffers that might already be referenced
by another submitted or unsubmitted GPU command. A synchronous map will
then trigger a flush and sync, at least on Linux that doesn't distinguish
between read- and write referencing. So map these buffers async. If they
for some obscure reason happen to be dirty (stream-output, buffer-copy),
the resource_buffer code will read-back and sync anyway. For persistent /
coherent buffers a corresponding read-back and sync will happen in the
kernel fault handler.

5 years agosvga: Fix index buffer uploads
Thomas Hellstrom [Thu, 11 Apr 2019 06:56:20 +0000 (08:56 +0200)]
svga: Fix index buffer uploads

In the case of SWTNL and index translation we were uploading index buffers
and then reading out from them using the CPU. Furthermore, when translating
indices we often cached the results with an upload_mgr buffer, causing the
cached indexes to be immediately discarded on the next write to that
upload_mgr buffer.

Fix this by only uploading when we know the index buffer is going to be
used by hardware. If translating, only cache translated indices if the
original buffer was not a user buffer. In the latter case when we're not
caching, use an upload_mgr buffer for the hardware indices.

This means we can also remove the SWTNL hand-crafted index buffer upload
mechanism in favour of the upload_mgr.

Finally avoid using util_upload_index_buffer(). It wastes index buffer
space by trying to make sure that the offset of the indices in the
upload_mgr buffer is larger or equal to the position of the indices in
the source buffer. From what I can tell, the SVGA device does not
require that.

Testing done: Piglit quick. No regressions.

glsl/nir: Add optimization pass for access flags

Right now, this just deduces when we can arbitrarily reorder SSBO and
image loads, matching the existing logic in radeonsi's TGSI->LLVM pass.
This approach can't handle some things that nir_opt_copy_prop_vars can,
but it can handle images, and with GCM it lets us hoist reads outside of
loops. We can also pass this information to LLVM which lets it do its
own optimizations on it.

This is GLSL only as I haven't tested it on Vulkan yet, and it would
probably need a few changes to work there.

ac,radeonsi: Always mark buffer stores as inaccessiblememonly

inaccessiblememonly means that it doesn't modify memory accesible via

forwarding, etc. ignore functions with this attribute. We don't
represent descriptors as pointers, so this property is always true of
buffer and image stores. There are plans to represent descriptors via
pointers, but this just means that now nothing is inaccessiblememonly,
as LLVM will then understand loads/stores via its usual alias analysis.

Radeonsi was mistakenly only setting it if the driver could prove that
there were no reads, and then it was cargo-culted into ac_llvm_build
and ac_llvm_to_nir. Rip it out of everything.
