Charmaine Lee 1b9b060f0e svga: use upload buffer if texture has pending changes 
When establishing a texture transfer map, if there is any pending changes on the
texture, instead of trying direct map with DONTBLOCK first, just
use the upload buffer path.

Fixes piglit tests gen-teximages, arb_copy_images-formats

Charmaine Lee 75b7296fc3 svga: fix resource_get_handle from resource created without SHARED bind flag 
When an EGLImage is created from a 2D texture and used for texture sharing,
the texture surface might not have been created with the SHARED bind flag.
To allow these surfaces for sharing, this patch sets the USAGE SHARED bit
for surfaces that can be potentially used for sharing even when the SHARED
bind flag is not originally set. Instead of unconditionally enabling the
SHARED bind flag for all surfaces and unnecessarily bypass the surface cache
optimization, this patch only enables the USAGE SHARED bit for surfaces
that also have the RENDER TARGET bind flag.
When the surface handle is inquired and if the surface is currently
marked as cachable, we will need to unset the cachable bit so
the surface handle will not be recycled again.

This patch fixes an assertion in svga_resource_get_handle() when the
EGL_MESA_image_dma_buf_export extension is used in webgl benchamrk running
from firefox in Fedora 37.

Roland Scheidegger 427ac51c10 llvmpipe: only use accurate_a0 hack if there are no textures bound 
This hack caused problems with some dx9 tests before (due to mipgen
test using nearest filter sampling with tex coords exactly between two
texels hence being extremely sensitive to arithmetic inaccuracies),
and we can no longer distinguish this by using pixel_offset to not get
it enabled. But to pass other tests we don't really need the hack when
there's texture sampling involved anyway.

Alyssa Rosenzweig 029c686c6d asahi: Implement color masks with masked stores 
Blend states can require masking colour. Currently, this is handled by
nir_lower_blend, which lowers masks to a read-modify-write operation as required
on Mali hardware. However, our "tilebuffer store" instruction supports a write
mask, allowing us to write only a subset of channels to the tilebuffer. It's
more efficient to use that than to emit pointless tilebuffer loads.

Note that even without tilebuffer loads, non-opaque masks don't work with opaque
pass types.  Here, we handle this with a translucent pass type, which gets HSR
to do the right thing and is consistent with the pass type used previously.
However, it's a bit heavy handed -- Apple manages to use an opaque pass type
with masking but with some unknown HSR fields twiddled. IMO reverse-engineering
those details shouldn't block this because this gets us closer to optimal (just
not all the way there) and is strictly better than what we had before.

If radv is initialized before radeonsi, doing:

is incorrect because the device was initialized using the fd
passed by radv.

libdrm has a helper to query the fd used to create the device,
so use it.

We also need to init the kms_handles table in this case
because we're going to share BOs between radeonsi's fd and
the device fd.
