i965: Add blorp-based texture upload and download paths

v1 (Topi Pohjolainen): original patch.

v2 (Topi Pohjolainen):
   - Fix return value (s/MESA_FORMAT_NONE/false/) (Anuj)
   - Move _mesa_tex_format_from_format_and_type() just
     in the end avoiding additional if-block (Anuj)
   - Explain better the array alignment restriction (Anuj)
   - Do not bail out in case of gl_pixelstore_attrib::ImageHeight,
     it is handled by _mesa_image_offset() automatically (Ken).
   - Support 1D_ARRAY by flipping depth, width and y, z (Ken).

v3 (Topi Pohjolainen):
   - Contrary to v2, do not try to handle
     gl_pixelstore_attrib::ImageHeight. Currently there are no
     tests in piglit or cts for it. One could possibly copy or
     modify tests/texturing/texsubimage.c. There, however, seems
     to be number of corner cases to consider. Moreover, current
     meta path applies the packing height for both source and
     targets when determining the offset. This would probably
     require re-visiting also.

v4 (Topi Pohjolainen): Rebased on top of merged drm-bacon

v5 (Jason Ekstrand):
   - Move to brw_blorp.c
   - Significant refactoring
   - Fixed 1-D array textures
   - Simplified handling of PBOs vs. CPU data.
   - Handle gl_pixelstore_attrib::ImageHeight.  It turns out there are
     piglit tests that cover this. The original version was failing them
     because of an error in the way it handled 1-D array textures.
   - Add support for texture download

v6 (Kenneth Graunke): Rebase fixes:
   - Use intel_miptree_check_level_layer instead of deleted fields
   - Update for mesa_format_supports_render[] rename.
   - Pass 'false' (read-only) to intel_bufferobj_buffer

v7 (Kenneth Graunke):
   - Fix brw_blorp_download_miptree to pass 'false' (not read only) for
     the destination buffer (caught by Chris Wilson).
   - Fix blorp_get_client_bo to pass intel_bufferobj_buffer !read_only
     for the 'writable' parameter instead of 'false' (caught by Jason).
   - Support GL_BGR, GL_BGRA, GL_BGRA_INTEGER, GL_BGR_INTEGER, allowing
     us to use this for ReadPixels on the window system buffer (caught
     by Chris Wilson).
   - Fix y-flipping bugs in download path (exposed by BGRA support).
   - Fix false vs. NULL return value in blorp_get_client_bo.

Kenneth Graunke [Sat, 9 Sep 2017 07:20:26 +0000 (00:20 -0700)]
i965: Ignore GL_SKIP_DECODE_EXT for textures accessed via texelFetch().

The GL_EXT_texture_sRGB_decode spec says:

"The conversion of sRGB color space components to linear color space is
 always performed if the texel lookup function is one of the texelFetch
 builtin functions.

 Otherwise, if the texel lookup function is one of the texture builtin
 functions or one of the texture gather functions, the conversion of sRGB
 color space components to linear color space is controlled by the
 TEXTURE_SRGB_DECODE_EXT parameter.

 If the TEXTURE_SRGB_DECODE_EXT parameter is DECODE_EXT, the conversion
 of sRGB color space components to linear color space is performed.

 If the TEXTURE_SRGB_DECODE_EXT parameter is SKIP_DECODE_EXT, the value
 is returned without decoding. However, if the texture is also accessed
 with a texelFetch function, then the result of texture builtin functions
 and/or texture gather functions may be returned with decoding or without
 decoding."

This patch makes i965 force sRGB decoding for any textures accessed via
texelFetch().  If textures are accessed via texelFetch() and a regular
texture access function, this will affect the other ones too - which is
fine - it's undefined according to the last paragraph quoted.

We could make both work, but we'd have to emit multiple SURFACE_STATEs,
and have two binding table sections, like we do for texture gather hacks
on older platforms.

i965: Fix output register sizes when multiple variables share a slot.

ARB_enhanced_layouts allows multiple output variables to share the same
location - and these variables may not have the same sizes.  For
example, consider these output variables:

   // consume X/Y/Z components of 6 vectors
   layout(location = 0) out vec3 a[6];

   // consumes W component of the first vector
   layout(location = 0, component = 3) out float b;

Looking at the first declaration, we see that VARYING_SLOT_VAR0 needs 24
components worth of space (vec3 padded out to a vec4, 4 * 6 = 24).  But
looking at the second declaration, we would think that VARYING_SLOT_VAR0
needs only 4 components of space (a single float padded out to a vec4).

nir_setup_outputs() only considered the space requirements of the first
declaration it happened to see, so if 'float b' came first, it would
underallocate the output register space, causing brw_fs_validator.cpp
to assert fail about inst->dst.offset exceeding the register size.

However, CCS can cause problems.  If the shader is reading one set of

we'd never get to the fma instruction emission code.

7 years agoradv: lower ffma in nir.

radv: lower ffma in nir.

So it appears the Vulkan SPIR-V fma opcode can be equivalent to a
mad operation, and the fma hw opcode on AMD hw is issued like a double
opcode so is slower. Also the radeonsi stack does this.

This appears to improve performance on a number of games from Feral,
and thanks to Feral for noticing the problem.

I'm reposting this one as Marek indicated he thinks this is what
we should be doing on AMD hw.
