mesa: Returns a GL_INVALID_VALUE error on several APIs when buffer size is negative
Section 2.3.1 (Errors) of the OpenGL 4.5 spec says:
"If a negative number is provided where an argument of type sizei or
sizeiptr is specified, an INVALID_VALUE error is generated.
This patch adds checks for negative buffer size values passed to different APIs.
It also moves up the check on other APIs that already had it, making it the first
error check performed in the function, for consistency.
While there may be other APIs throughtout the code lacking this check (or at least
not at the beginning of the function), this patch focuses on the cases that break
the dEQP tests listed below. It could be a good excersize for the future to check
all other cases, and improve consistency in the order of the checks throughout the
whole Mesa code base.

glsl: Improve precision of mod(x,y)
Currently, Mesa uses the lowering pass MOD_TO_FRACT to implement
mod(x,y) as y * fract(x/y). This implementation has a down side though:
it introduces precision errors due to the fract() operation. Even worse,
since the result of fract() is multiplied by y, the larger y gets the
larger the precision error we produce, so for large enough numbers the
precision loss is significant. Some examples on i965:
Operation Precision error
-----------------------------------------------------
mod(-1.
951171875, 1.
9980468750) 0.
0000000447
mod(121.57, 13.29) 0.
0000023842
mod(3769.12, 321.99) 0.
0000762939
mod(3769.12, 1321.99) 0.
0001220703
mod(-987654.125, 123456.984375) 0.
0160663128
mod( 987654.125, 123456.984375) 0.
0312500000
This patch replaces the current lowering pass with a different one
(MOD_TO_FLOOR) that follows the recommended implementation in the GLSL
man pages:
mod(x,y) = x - y * floor(x/y)
This implementation eliminates the precision errors at the expense of
an additional add instruction on some systems. On systems that can do
negate with multiply-add in a single operation this new implementation
would come at no additional cost.

This is accomplished by inserting a 4-byte NOP instruction in the display

nir: add a helper function for getting the number of source components
Unlike with non-SSA ALU instructions, where if they're per-component
you have to look at the writemask to know which source channels are
being used, SSA ALU instructions always have all the possible channels
enabled so we can just look at the number of components in the SSA
definition for per-component instructions to say how many source
components are being used.
v2: use new name nir_ssa_alu_instr_src_components()

i965: Implemente a tiled fast-path for glReadPixels and glGetTexImage
Added intel_readpixels_tiled_mempcpy and intel_gettexsubimage_tiled_mempcpy
functions. These are the fast paths for glReadPixels and glGetTexImage.
On chrome, using the RoboHornet 2D Canvas toDataURL test, this patch cuts
amount of time spent in glReadPixels by more than half and reduces the time
of the entire test by 10%.
v2: Jason Ekstrand <jason.ekstrand@intel.com>
- Refactor to make the functions look more like the old
intel_tex_subimage_tiled_memcpy
- Don't export the readpixels_tiled_memcpy function
- Fix some pointer arithmatic bugs in partial image downloads (using
ReadPixels with a non-zero x or y offset)
- Fix a bug when ReadPixels is performed on an FBO wrapping a texture
miplevel other than zero.
v3: Jason Ekstrand <jason.ekstrand@intel.com>
- Better documentation fot the *_tiled_memcpy functions
- Add target restrictions for renderbuffers wrapping textures
v4: Jason Ekstrand <jason.ekstrand@intel.com>
- Only check the return value of brw_bo_map for error and not bo->virtual
v5: Jason Ekstrand <jason.ekstrand@intel.com>
- Don't unnecessarily repeat a comment

i965/tiled_memcpy: Add tiled-to-linear paths

linear memory. These are very similar to the existing linear-to-tiled

i965: Refactor tiled memcpy functions and move them into their own file
This commit refactors the tiled_memcpy code in intel_tex_subimage.c and
moves it into its own file intel_tiled_memcpy files. Also, xtile_copy and
ytile_copy are renamed to linear_to_xtiled and linear_to_ytiled
respectively. The *_faster functions are similarly renamed.
There was also a bit of logic to select between the the libc provided
memcpy function and our custom memcpy that does an RGBA -> BGRA swizzle.
This was moved into an intel_get_memcpy function so that rgba8_copy can
live (and be inlined) in intel_tiled_memcpy.c.

- Better commit message
- Fix up the copyright on the intel_tiled_memcpy files

i965/tex_subimage: Use the fast tiled path for rectangle textures
There's no reason why we should be doing this for 2D textures and not
rectangles. Just a matter of adding another hunk to the condition.
