freedreno/ir3: Handle GL_NONE in get_num_components_for_glformat()
An earlier patch that introduced the function failed to handle the case
where an image format layout qualifier is not specified, which is allowed
on desktop GL profiles. In these cases, nir_variable's image format is
GL_NONE, and we don't need to print a debug message for those.

docs: Add an encouraging note about providing reviews and acks.
Across several projects I've seen new contributors say "I wasn't sure if I
should provide a review tag since I'm not really an expert in this area."
Everyone I know already applies some implicit weighting to reviews from
different people, so encourage participation.

This calls the expensive uif offset function once per utile, but it still
gets us a 212.218% +/- 2.41216% (n=10) win on 1024x1024 glTexImage over
calling it on each pixel.
v3d: Implement texture_subdata to reduce teximage upload copies.
This lets us store the non-PBO glTexImage data directly into the tiled
image without making an extra untiled memcpy for the gallium transfer.
Improves 1024x1024 TexImage perf by ~19%, mostly from not thrashing around
in the kernel mapping and unmapping the transfer's temporary area.
v3d: Fix check for TFU job completion in the simulator.
We're waiting for the jobs-completed count to increment (with wrapping),
not to reach its starting state. This mostly ended up working out because
the next v3d_hw_tick() for a submit CL would end up doing the TFU
operation first, but it did fail when a blit was used for glReadPixels()
at the end of a test.
Fixes: ee0549ff9a ("v3d: Add the V3D TFU submit interface to the simulator.")
v3d: Put the dst bo first in the list of BOs for TFU calls.
In the UAPI, the first BO is the destination, and the one the kernel
should do an exclusive reservation on. Currently we only do exclusive
reservations, anyway. However, in the simulator path I was only copying
back the "destination" BO (actually src in this case), and this caused
regressions once I fixed the simulator to actually complete TFU before
returning (since otherwise, the TFU op would happen at the start of the
next CL submit and the draw would get the right contents).
Fixes: 976ea90bdc ("v3d: Add support for using the TFU to do some blits.")
nir: properly find the entry to keep in copy_prop_vars
When copy propagation handles a store/copy, it iterates the current
copy entries to remove aliases, but keeps the "equal" entry (if
exists) to be updated.
The removal step may swap the entries around (to ensure there are no
holes), invalidating previous iteration pointers. The bug was saving
such pointer to use later. Change the code to first perform the
removals and then find the remaining right entry.
This was causing updates to be lost since they were being made to an
entry that was not part of the current copies.

nir: properly clear the entry sources in copy_prop_vars
When updating a copy entry source value from a "non-SSA" (the data
come from a copy instruction) to a "SSA" (the data or parts of it come
from SSA values), it was possible to hold invalid data in ssa[0]
depending on the writemask. Because the union, ssa[0] could contain a
pointer to a nir_deref_instr left-over from previous non-SSA usage.
Change code to clean up the array before use to avoid invalid data
around.

virgl: modify how we handle GL_MAP_FLUSH_EXPLICIT_BIT
Previously, we ignored the the glUnmap(..) operation and
flushed before we flush the cbuf. Now, let's just flush
the data when we unmap.
Neither method is optimal, for example:
glMapBufferRange(.., 0, 100, GL_MAP_FLUSH_EXPLICIT_BIT)
glFlushMappedBufferRange(.., 25, 30)
glFlushMappedBufferRange(.., 65, 70)
We'll end up flushing 25 --> 70. Maybe we can fix this later.
