The function segfaulted when a game called glTexSubImage2D on a texture
with internalformat/format/type = GL_SLUMINANCE8/GL_BGRA/GL_UNSIGNED_BYTE.
The function only supports MESA_FORMAT_ARGB8888 and returns early if it
detects an unsupported format. Clearly, its detection condition was
insufficient. This patch fixes it to explicity check for
MESA_FORMAT_ARGB8888.
Note: This is a candidate for the 9.0 branch (fixes 413c491).

Haswell supports EXT_texture_swizzle and legacy DEPTH_TEXTURE_MODE
swizzling by setting SURFACE_STATE entries. This means we don't have to
bake the swizzle settings into the shader code by emitting MOV
instructions, and thus don't have to recompile shaders whenever the
swizzles change.
Unfortunately, we can't handle GL_ALPHA this way: unlike all the others,
which store the comparison result in the .r channel (and possibly others
as well), GL_ALPHA puts it in the .a channel. The GLSL 1.30+ style
functions which return a float always simply return the .r channel,
which would be zero if we handled this as a surface override. In this
case, fall back to doing it the old way. DEPTH_TEXTURE_MODE = GL_ALPHA
isn't an interesting performance path anyway.

Fixes valgrind errors in piglit test
oes_compressed_etc1_rgb8_texture-miptree: an invalid write in
_mesa_store_compressed_store_texsubimage() at line 4406 and invalid reads
in texcompress_etc_tmp.h:etc1_parse_block().
The calculation of the size of the temporary etc1 buffer allocated by
intel_miptree_map_etc1() was incorrect. Sometimes the allocated buffer was
too small, sometimes too large. This patch corrects the size to that
expected by _mesa_store_compressed_store_texsubimage().

GLES 3 supports sRGB functionality, but it does not expose the
GL_FRAMEBUFFER_SRGB enable/disable bit. Instead the implementation
is expected to behave as though that bit is always enabled.
This patch ensures that ctx->Color.sRGBEnabled (the internal variable
tracking GL_FRAMEBUFFER_SRGB) is initially true in GLES 2/3 contexts,
and that it cannot be modified through the GLES 3 API.
This is safe for GLES 2, since ctx->Color.sRGBEnabled has no effect on
non-sRGB formats, and GLES 2 doesn't support any sRGB formats.

Previously, meta logic was saving and restoring the value of
GL_FRAMEBUFFER_SRGB in an ad-hoc fashion. As a result, it was not
properly disabled and/or restored for some meta operations.
This patch causes GL_FRAMEBUFFER_SRGB to be saved/restored in the
conventional way of meta-ops (using _mesa_meta_begin() and
_mesa_meta_end()). It is now reliably saved/restored for
_mesa_meta_BlitFramebuffer, _mesa_meta_GenerateMipmap, and
decompress_texture_image, and preserved for all other meta ops.
Fixes piglit tests "ARB_framebuffer_sRGB/blit renderbuffer
{linear_to_srgb,srgb} scaled {disabled,enabled}".

GLES3 supports sRGB formats, but it does not support the
GL_FRAMEBUFFER_SRGB enable/disable flag (instead it behaves as if this
flag is always enabled). Therefore, meta ops that need to disable
GL_FRAMEBUFFER_SRGB will need a backdoor mechanism to do so when the
API is GLES3.
We were already doing a similar thing for GL_MULTISAMPLE, which has
the same constraints.

This patch reduces the time spent in glTexImage and glTexSubImage by
over 5x on Sandybridge for the workload described below.
It adds a new fast path for glTexImage2D and glTexSubImage2D,
intel_texsubimage_tiled_memcpy, which is optimized for Google Chrome's
paint rectangles. The fast path is implemented only for 2D GL_BGRA
textures for chipsets with a LLC.
=== Performance Analysis ===
Workload description:
Personalize your google.com page with a wallpaper. Start chromium
with flags "--ignore-gpu-blacklist --enable-accelerated-painting
--force-compositing-mode". Start recording with chrome://tracing. Visit
google.com and wait for page to finish rendering. Measure the time spent
by process CrGpuMain in GLES2DecoderImpl::HandleTexImage2D and
HandleTexSubImage2D.
System config:

v2:
- Replace check for `intel->gen >= 6` with `intel->has_llc`, per
danvet.
- Fix typo in comment, s/throuh/through/.
- Swap 'before' and 'after' rows in stat table.
v3:
- If the current batch references the bo, then flush batch before mapping
the bo. Found by Chris.
- Restrict supported texture images to level 0 of target
GL_TEXTURE_2D. This avoids an arithmetic bug in calculating image
offsets within the miptree, found by Paul. This restriction does not
diminish this patch's benefit to Chrome OS performance.
- Use less instructions for bit6 swizzling, suggested by Paul.
- Remove erroneous comment about Y-tiling, for Paul.
- Print perf_debug messages when flushing and stalling.
- Update stats in commit message; run workload under a release build
rather than a debug build.

A game we're working with leaves scissoring enabled, but frequently sets
the scissor rectangle to the size of the whole screen. In that case,
scissoring has no effect, so it's safe to go ahead with a fast clear.
Chad believe this should help with Oliver McFadden's "Dante" as well.
v2/Chad: Use the drawbuffer dimensions rather than the miptree slice
dimensions. The miptree slice may be slightly larger due to alignment
restrictions.

Commit e2249e8c4d06a85d6389ba1689e15d7e29aa4dff (i965/blorp: Add
support for blits between SRGB and linear formats) changed blorp to
always configure surface states for in linear format (even if the
underlying surface is sRGB). This allowed sRGB-to-linear and
linear-to-sRGB blits to occur without causing the image to be
inappropriately brightened or darkened.
However, it broke sRGB MSAA resolves, since they rely on the
destination buffer format being sRGB in order to ensure that samples
are averaged together in sRGB-correct fashion.
This patch fixes the problem by instead configuring the source buffer
to use the *same* format as the destination buffer. This ensures that
the image won't be brightened or darkened, but preserves proper sRGB
averaging.
Fixes piglit tests "EXT_framebuffer_multisample/accuracy srgb".
