I was looking into some minor 422 issues/discrepencies I noticed long
ago using vdpau on my rv790.
I noticed that there is code that is halving height rather than width -
422 is full height AFAIK.
Making the changes below doesn't actually make any noticable difference
to what I was looking into.
Maybe there are more but here's three I've found so far

Since we expose non-NV12 formats as supported when there is no decoer
profile selected, make sure that those formats are actually allowed to
be allocated.

Previously, we were asserting that each driver specified an NConfigOptions
exactly equal to the number of options they supplied, leading to frequent
bugs when people would forget to adjust the value when adjusting driver
options. Instead, just overallocate the table by a bit and leave sanity
checking to the assert in findOption().

The surface allocator understands the scanout flag just fine.
This seems to improve performance for Ubuntu Unity on top of st/xorg

This started as an attempt to add support for MSAA texture transfers and
MSAA depth-stencil decompression for the DB->CB copy path.
It has gotten a bit out of control, but it's for the greater good.
Some changes do not make much sense, they are there just to make it look
like the other driver.
With a few cosmetic modifications, r600_texture.c can be shared with
a symlink.

and texturing as required by GL 3.2 and GL_ARB_texture_multisample.

This is basic MSAA support which should work with most apps.
Some features are missing, those will be implemented by other commits.

It moves all sampler view descriptors to a buffer.
It supports partial resource updates and it can also unbind resources
(required for FMASK texturing).
The buffer contains all sampler view descriptors for one shader stage,
represented as an array. On top of that, there are N arrays in the buffer,
which are used to emulate context registers as implemented by the previous
ASICs (each array is a context).
This uses the RCU synchronization approach to avoid read-after-write hazards
as discussed in the thread:
"radeonsi: add FMASK texture binding slots and resource setup"
CP DMA is used to clear the descriptors at context initialization and to copy
the descriptors from one context to the next.
v2: - use PKT3_DMA_DATA on CIK (I'll test CIK later)
- turn the bool CP DMA parameters into self-explanatory flags
- add a nice simple API for packet emission to radeon_winsys.h
- use 256 contexts, 128 causes texture corruption in openarena
It shouldn't be necessary to call radeon_winsys::cs_flush() from
radeonsi_launch_grid(), because the state tracker is responsible for
flushing the pipeline at the appropriate time. The current behavior is
also wrong, because radeonsi_launch_grid() submits packets to the
compute ring, but when the state tracker calls pipe->flush() everything
is submitted to the graphics ring. This has the potential to create a
race condition.
The downside of removing this flush is that the compute dispatch packets
will be sent to the graphics ring rather than the compute ring.
In the future we will need to come up with a way to detect 'compute'
command streams and submit them to the appropriate ring.

Doing the comparisons pre-filter is highly recommended by OpenGL (and d3d9)
and definitely required by d3d10.
This actually doesn't do it pre-filter but more "in-filter" as otherwise
need to push the comparisons even further down into fetch code and this
also trivially allows using a somewhat cheaper lerp.
Doing it pre-filter would actually have some performance advantage for UNORM
formats (because the comparisons should be done in texture format, we'd only
need to convert the shadow ref coord to texture format once, but in turn would
save converting the per-sample texture values to floats) but this gets a bit
messy as this has implications for border color handling as well (which needs
to be done prior to depth comparisons, hence would also need to convert border
color to texture format too or use some other tricks like doing separate border
color / shadow ref comparison and simply using that result directly when doing
border replacement).
Should make no difference for nearest filtering, and performance for linear
filtering should be mostly the same too (essentially have one more comparison
instruction per sample, and replace the sub/mul/add lerp with a sub/and/and/add
special "lerp" which all in all shouldn't be much of a difference).

E.g. the Source engine seems to always write to gl_ClipVertex, but normally
doesn't enable any GL_CLIP_DISTANCEn states. This change removes some
irrelevant parts from the generated vertex shader code in such cases.

This is a very well hidden bug found by accident (only the fixed glean
tstencil2 test so far seems to hit it).
We must use new mask with combined s_pass values and orig_mask values
for zpass/zfail stencil ops, otherwise both the sfail op and one of
zpass/zfail op are applied (probably not hit in most tests because
some of the ops tend to be KEEP usually).
Note: this is a candidate for the 9.2 branch.
