* i965/blorp: Fix narrowing warnings.Paul Berry2012-09-211-3/+3
| | | | | | | | | | | 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. Reviewed-by: Eric Anholt <[email protected]>
* i965: Remove brw_set_predicate_inverse(p, true) from scratch offset codeKenneth Graunke2012-09-211-1/+0
| | | | | | | | | | | | | | Given that it exists between a push/pop of instruction state, this call can only affect the MOV or ADD instruction generated just below it. Neither of those instructions are predicated, so it makes no sense to ask for the inverse predicate. This fixes grumblings from the simulator debugger, which was complaining about an invalid predicate.

* mesa: Don't override S3TC internalFormat if data is pre-compressed.Kenneth Graunke2012-09-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Commit 42723d88d intended to override an S3TC internalFormat to a generic compressed format when the application requested online compression of uncompressed data. Unfortunately, it also broke pre-compressed textures when libtxc_dxtn isn't installed but the extensions are forced on. Both glCompressedTexImage2D() and glTexImage2D() call teximage(), which calls _mesa_choose_texture_format(), hitting this override code. If we have actual S3TC source data, we can't treat it as any other format, and need to avoid the override. Since glCompressedTexImage2D() passes in a format of GL_NONE (which is illegal for glTexImage), we can use that to detect the pre-compressed case and avoid the overrides. Fixes a regression since 42723d88d370a7599398cc1c2349aeb951ba1c57. NOTE: This is a candidate for the 9.0 branch.

* i965/blorp: Add support for blits between SRGB and linear formats.Kenneth Graunke2012-09-202-4/+8
| | | | | | | | | | | | Fixes colorspace issues in L4D2 when multisampling is enabled (the scene was far too dark, but the flashlight area was way too bright). The nVidia and AMD binary drivers both allow this kind of blit. NOTE: This is a candidate for the 9.0 branch.

* mesa: Ignore SRGB when determining compatible resolve formats.Kenneth Graunke2012-09-201-1/+2
| | | | | | | | | | | | | | | MSAA resolves and other blit-like operations ignore SRGB state anyway, so we should be able to safely allow resolves between compatible SRGB/linear formats like SRGBA8 and RGBA8888. This matches the behavior of the nVidia and AMD binary drivers. Fixes completely black rendering when using multisampling in L4D2. NOTE: This is a candidate for the 9.0 branch.

* llvmpipe: fix overflow bug in total texture size computationBrian Paul2012-09-201-2/+16
| | | | | | | | | | | | | | | | v2: use uint64_t for the total_size variable, per Jose. Also add two earlier checks for exceeding the max texture size. For example a 1K^3 RGBA volume would overflow the lpr->image_stride variable. Use simple algebra to avoid overflow in intermediate values. So instead of "x * y > z" use "x > z / y". This should work if we happen to be on a platform that doesn't have 64-bit types. Reviewed-by: Jose Fonseca <[email protected]>

* r600g: Use LOOP_START_DX10 for loopsTom Stellard2012-09-193-2/+11
| | | | | | | | | | LOOP_START_DX10 ignores the LOOP_CONFIG* registers, so it is not limited to 4096 iterations like the other LOOP_* instructions. Compute shaders need to use this instruction, and since we aren't optimizing loops with the LOOP_CONFIG* registers for pixel and vertex shaders, it seems like we should just use it for everything.

* mesa: rework texture size error checkingBrian Paul2012-09-174-225/+161
| | | | | | | | | | | | | | | | | | | | | | There are two aspects to texture image size checking: 1. Are the width, height, depth legal values (not negative, not larger than the max size for the mipmap level, etc)? 2. Is the texture just too large to handle? For example, we might not be able to really allocate memory for a 3D texture of maxSize x maxSize x maxSize. Previously, we did (1) via the ctx->Driver.TestProxyTextureImage() hook but those tests are really device-independent. Now we do (2) via that hook since the max texture memory and texture shape are device-dependent. Also, (1) is now done outside the general texture parameter error checking functions because of the special interaction with proxy textures. The recently introduced PROXY_ERROR token is removed. The teximage() and copyteximage() functions are bit simpler now (less if-then nesting, etc.) Reviewed-by: Jose Fonseca <[email protected]>
