intel: Fix segfault in intel_texsubimage_tiled_memcpy
did fix the segfault, but introduced yet another bug. From Anholt: """You
need to still test format/type, because that's the incoming format (e.g.
GL_RGBA/GL_FLOAT) that you're trying to memcpy."""
This patch re-introduces the checks on the incoming format and type.

In commit 091eb15b694, Jordan changed get_temp_image_type() to use
_mesa_get_format_datatype() instead of returning GL_FLOAT. That has
several possible return values: GL_FLOAT, GL_INT, GL_UNSIGNED_INT,
GL_SIGNED_NORMALIZED, and GL_UNSIGNED_NORMALIZED.
We do want to use GL_INT/GL_UNSIGNED_INT for integer formats. However,
we want to continue using GL_FLOAT for the normalized fixed-point types.
There isn't any code in pack.c to handle GL_(UN)SIGNED_NORMALIZED.
Fixes oglconform's fboarb advanced.blit.copypix, which was regressed by
commit 091eb15b694a396f8453093575ccec2db7f14eb8.

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.

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.

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.

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.

- 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

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.

v2/Chad: Use the drawbuffer dimensions rather than the miptree slice
dimensions. The miptree slice may be slightly larger due to alignment

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.

This patch is a band-aid fix for a bug in commit 5fd67fa (i965/blorp:
Reduce alignment restrictions for stencil blits), which causes
multisampled stencil blits to work incorrectly on Sandy Bridge.
When blitting to or from a normal stencil buffer, we have to use a
coordinate transformation that swizzles coordinates to account for the
fact that stencil buffers use W tiling, but the most similar tiling
format available for textures and render targets is Y tiling. The
differences between W and Y tiling cause pixels to be scrambled within
a block of size 8x4 (width x height) as measured relative to a W tile,
or 16x2 as measured relative to a Y tile. So in order to make sure
that pixels at the edges of the blit aren't lost, we need to align the
rendering rectangle (and the buffer sizes) to multiples of the 8x4
block size. This alignment happens in the brw_blorp_blit_params
constructor, whereas the determination of how to swizzle the
coordinates happens during code generation, in the
brw_blorp_blit_program class.
When blitting to or from a multisampled stencil buffer, the coordinate
swizzling is more complex, because it has to account for the
interleaving pattern of samples, which uses 4x4 blocks for 4x MSAA and
8x4 blocks for 8x MSAA. The end result is that if multisampling is in
use, the 16x2 block size (relative so a Y tile) needs to be expanded
to 16x4, and the corresponding size relative to a W tile expands to
8x8.
The problem doesn't affect Ivy Bridge severely enough to crop up in
Piglit tests because on Ivy Bridge we have to disable multisampling
when blitting *to* a multisampled stencil buffer (the blorp compiler
generates code to compensate for the fact that multisampling is
disabled). However I suspect a bug is still present because we don't
disable multisampling when blitting *from* a multisampled stencil
buffer.
This patch fixes the problem by doubling the vertical alignment
requirement when blitting to or from a multisampled stencil buffer,
and multisampling has not been disabled.
In the long run I would like to rework the brw_blorp_blit_params
constructor--it's difficult to follow and has had several subtle bugs
like this one. However this band-aid fix should be suitable for
cherry-picking to release branches.
Fixes Piglit tests "unaligned-blit {2,4} stencil {msaa,upsample}" on
Sandy Bridge.

Blorp has to convert rectangle coordinates from integers to floats in
order to send them down the GPU pipeline. Recent versions of GCC
issue a warning for this, since a float is not capable of precisely
representing all possible 32-bit integer values. Suppress the warning
with an explicit type cast in the case of blorp, since rectangle
coordinates will never be large enough to cause a loss of precision.
