5ce639c001 radeon/uvd: don't expose HEVC on old UVD hw (v3)
The section for UVD 2 and older was not updated
when HEVC support was added. Reported by Kano
on irc.

v2: integrate the UVD2 and older checks into the
main switch statement.
v3: handle encode checking as well.  Encode is
already checked in the top case statement, so
drop encode checks in the lower case statement.

2294f6f311 mesa/glformats: Undo code changes from _mesa_base_tex_format() move
The refactoring commit, c6bf1cd, accidentally reverted cd49b97
and 99b1f47. These changes caused more code to be added to the
function and removed the existing support for ASTC. This patch
reverts those modifications.

v2. Actually include ASTC support again.

in the rendering going astray, to a stale buffer, and not shown on the

4d215a25d5 i965/vec4: fill src_reg type using the constructor type parameter
The src_reg constructor that received the glsl_type was using it
only to build the swizzle, but not to fill this->type as dst_reg
is doing.

This caused some type mismatch between movs and alu operations
on the NIR path, so copy propagation optimization was not applied
to remove unneeded movs if negate modifier was involved. This was
first detected on minus (negate+add) operations.

Below is example when using MESA_GLES_VERSION_OVERRIDE=3.1.

Before:
	"3.1 Mesa 11.1.0-devel (git-24a1a15)"

After:
	"OpenGL ES 3.1 Mesa 11.1.0-devel (git-78042ff)"

cd6ff70856 glsl: Allow built-in functions as constant expressions in OpenGL ES 1.00
In d4a24745 (August 2012), Paul made functions calls not be constant
expressions in GLSL ES 1.00.  Since this feature was added in desktop
GLSL 1.20, we believed that it was added in GLSL ES 3.00.  That turns
out to be completely wrong.  Built-in functions have always been allowed
as constant expressions in GLSL ES, and the patch adds the (many) spec
quotations to prove it.

While we never previously encountered this, a later patch enforces a GLSL
ES 1.00 rule that global variable initializers must be constant
expressions.  Without this fix, several dEQP tests fail.

The point is to avoid having to re-validate all image units when
_NEW_TEXTURE is flagged, which can be expensive if the driver exposes
a large number of image units.  This has been reported to fix a 36%
performance regression in the Synmark2 Multithread benchmark on the
i965 driver which exposes 192 image units.

df361e2311 mesa: Skip redundant texture completeness checking during image validation.
The call to _mesa_test_texobj_completeness() is unnecessary if the
texture is already known to be complete.  If the texture object is
dirtied in the meantime _BaseComplete and _MipmapComplete will be
reset to false.  _mesa_is_image_unit_valid() will start to be called
more frequently in a future commit, so it seems desirable to avoid the
unnecessary work.

7259f17eca mesa: Expose function to calculate whether a shader image unit is valid.
A future commit will remove all texture object-dependent derived state
from the image unit struct to make validation unnecessary on texture
state changes.  Instead of checking gl_image_unit::_Valid drivers will
be required to call this function when needed to find out whether an
image unit is in a valid state and whether access from the shader is
allowed.

37b647b979 i965: Don't tell the hardware about our UAV access.
The hardware documentation relating to the UAV HW-assisted coherency
mechanism and UAV access enable bits is scarce and sometimes
contradictory, and there's quite some guesswork behind this commit, so
let me summarize the background first: HSW and later hardware have
infrastructure to support a stricter form of data coherency between
shader invocations from separate primitives.  The mechanism is
controlled by the "Accesses UAV" bits on 3DSTATE_VS, _HS, _DS, _GS and
_PS (or _PS_EXTRA on BDW+), and the "UAV Coherency Required" bit on
the 3DPRIMITIVE command.

Regardless of whether "UAV Coherency Required" is set, the hardware
fixed-function units will increment a per-stage semaphore for each
request received if "Accesses UAV" is set for the same or any lower
stage.  An implicit DC flush is emitted by the lowermost stage with
"Accesses UAV" set once it's done processing the request, this also
happens regardless of the value of "UAV Coherency Required".  The
completion of the DC flush will cause the same stage and all previous
ones to decrement the semaphore, marking the UAV accesses for the
primitive as coherent with L3.

The "UAV Coherency Required" 3DPRIMITIVE bit will cause a pipeline
stall before any threads are dispatched for the first FF stage with
"Accesses UAV" set until the semaphore is cleared for the same stage.
Effectively this guarantees that UAV memory accesses performed by
previous primitives from any stage will be strictly ordered (and
thanks to the implicit DC flush visible in memory) with UAV accesses
from the following primitives.

None of this is required by the usual image, atomic counter and SSBO
GL APIs which have very relaxed cross-primitive coherency and ordering
requirements, so we don't actually ever set the "UAV Coherency
Required" bit -- Ordering with respect to shader invocations from
previous stages on the same primitive where there is a data dependency
is of course already guaranteed as the spec requires, regardless of
this mechanism being enabled.  We do set the "Accesses UAV" bits
though since my commit ac7664e493 (which
this patch partially reverts), mainly because of comments like the
following from the BDW PRM:

> 3DSTATE_GS
>[...]
> 12 Accesses UAV
>    Format: Enable
>    This field must be set when GS has a UAV access.

There are similar comments in the documentation for the other
3DSTATE_*S commands.  The "must" part is misleading and unjustified
AFAIK.  Most of the "Accesses UAV" bits don't seem to have any side
effects other than the implicit DC flushes and the related
book-keeping in anticipation for a subsequent primitive with "UAV
Coherency Required" set, so in most cases they are unnecessary and may
incur a performance penalty.  There is an exception though.  On Gen8+
the PS_EXTRA UAV access bit influences the calculation of the PS
UAV-only and ThreadDispatchEnable signals which on previous
generations were set explicitly by the driver, so we cannot always
avoid enabling it on the PS stage.

The primary motivation for this change is that in fact the hardware
coherency mechanism is buggy and will cause a rather non-deterministic
hang on Gen8 when VS is the only stage with "Accesses UAV" set and the
processing of a request terminates immediately after the implicit DC
flush is sent for a previous primitive with no additional vertices
being emitted for the second primitive, what will cause the hardware
to skip sending a second DC flush and cause the VS to stall
indefinitely waiting for a response from the DC (BDWGFX HSD 1912017).
This hardware bug can be reproduced on current master with the
spec@arb_shader_image_load_store@host-mem-barrier@Indirect/RaW piglit
subtest (if you have the patience to run it a few dozen times).

The proposed workaround is to insert CS STALLs speculatively between
3DPRIMITIVE commands when "Accesses UAV" is enabled for the VS stage
only.  Because this would affect one of the hottest paths in the
driver and likely decrease performance even further due to the
unnecessary serialization, and because we don't actually need the
implicit DC flushes, it seems better to just disable them.

3f802ebaf8 nouveau: make sure there's always room to emit a fence
I started seeing a lot of situations on nv30 where fence emission
wouldn't fit into the previous buffer (causing assertions). This ensures
that whenever checking for space, we always leave a bit of extra room
for the fence emission commands. Adjusts the nv30 and nvc0 fence
emission logic to bypass the space checking as well.

nouveau: avoid emitting new fences unnecessarily

Right now we emit on every kick, but this is only necessary if something
will ever be able to observe that the fence completed. If there are no
refs, leave the fence alone and emit it another day.

This also happens to work around an issue for the kick handler -- a kick
can be a result of e.g. nouveau_bo_wait or explicit kick, or it can be
due to lack of space in the pushbuf. We want the emit to happen in the
current batch, so we want there to always be enough space. However an
explicit kick could take the reserved space for the implicitly-triggered
kick's fence emission if it happened right after. With the new mechanism,
hopefully there's no way to cause two fences to be emitted into the same
reserved space.

We still have to push everything out, might as well kick earlier and

nouveau: avoid double-emitting fence

The act of ensuring that there is space can cause a flush to happen,
which will emit the current screen fence. If that is the fence we're
trying to wait on, then it will have been emitted as a result of doing
the PUSH_SPACE. Don't attempt to emit it a second time.

This reverts commit 30570b2629.

As mentioned by Ilia Mirkin:

 Please remove this one from your list of cherry-picked patches. While
  it fixes real issues on nv30 (and probably the other generations too),
  it appears to introduce some new ones on nvc0. I've figured out what's
  causing it, but haven't figured out a proper fix. Not sure I'll be
  able to before you do a release.

1a866b3e49 mesa: Correctly handle GL_BGRA_EXT in ES3 format_and_type checks
The EXT_texture_format_BGRA8888 extension (which mesa supports
unconditionally) adds a new format and internal format called GL_BGRA_EXT.
Previously, this was not really handled at all in
_mesa_ex3_error_check_format_and_type.  When the checks were tightened in
commit f15a7f3c, we accidentally tightened things too far and GL_BGRA_EXT
would always cause an error to be thrown.

There were two primary issues here.  First, is that
_mesa_es3_effective_internal_format_for_format_and_type didn't handle the
GL_BGRA_EXT format.  Second is that it blindly uses _mesa_base_tex_format
which returns GL_RGBA for GL_BGRA_EXT.  This commit fixes both of these
issues as well as adds explicit checks that GL_BGRA_EXT is only ever used
with GL_BGRA_EXT and GL_UNSIGNED_BYTE.
