* i965/fs: Calculate delta_x and delta_y together.Matt Turner2015-04-217-74/+79

* i965/fs: Emit ADDs for gl_FragCoord, not virtual opcodes.Matt Turner2015-04-215-51/+8
| | | | | | | | | | These were used only on Gen4 and 5. emit_interpolation_setup_gen6() emits ADDs directly. The virtual opcodes weren't providing anything useful. I'm going to repurpose these opcodes, so deleting and readding them makes it simpler to see what's going on. Reviewed-by: Jason Ekstrand <[email protected]>

| | | | | | | | Like LINE (commit 92346db0), src0 must have a scalar region. Setting src1's region to <8,8,1> lets us pass a properly sized combined delta_xy argument in a few commits without getting a bogus <16,16,1> region. Reviewed-by: Jason Ekstrand <[email protected]>

* i965: Replace guess_execution_size with something simpler.Matt Turner2015-04-214-27/+35
| | | | | | | | | | | | | | | | | | | | | | | guess_execution_size() does two things: 1. Cope with small destination registers. 2. Cope with SIMD8 vs SIMD16 mode. This patch replaces the first with a simple if block in brw_set_dest: if the destination register width is less than 8, you probably want the execution size to match. (I didn't put this in the 3src block because it doesn't seem to matter.) Since only the FS compiler cares about SIMD16 mode, it's easy to just set the default execution size there. This pattern was already been proven in the Gen8+ generator, but we didn't port it back to the existing generator when we combined the two. This is based on a patch from Ken from about a year ago. I've rebased it and and fixed a few bugs. Reviewed-by: Jason Ekstrand <[email protected]>

* i965/skl: Fix the qpitch valueNeil Roberts2015-04-202-13/+59
| | | | | | | | | | | | | | | | | | On Skylake the qpitch value is uploaded as part of the surface state so we don't need to add the extra rows that are done for other generations. However for 3D textures it needs to be aligned to the tile height and for depth/stencil textures it needs to be a multiple of 8. Unlike previous generations the qpitch is measured as a multiple of the block size for compressed surfaces. When the horizontal mipmap layout is used for 1D textures then the qpitch is measured in pixels instead of rows. v2: Align the depth/stencil textures to a multiple of 8 v3: Add an assert that ALL_SLICES_AT_EACH_LOD is not used. Ignore the vertical alignment when picking the qpitch for 1D_ARRAY textures. Reviewed-by: Ben Widawsky <[email protected]> Reviewed-by: Anuj Phogat <[email protected]>
* i965/skl: Don't use ALL_SLICES_AT_EACH_LODNeil Roberts2015-04-201-10/+20
| | | | | | | | | | | | | | | | | | | | | The render surface state command for Skylake doesn't have the surface array spacing bit so it's not possible to select this layout. I think it was only used in order to make it pick a tightly-packed qpitch value that doesn't include space for the mipmaps. However this won't be necessary after the next patch because it will automatically pick a packed qpitch value whenever first_level==last_level. It is better to remove this layout entirely on Gen8+ because although it can effectively be implemented with a small qpitch value when there are no mipmaps it isn't possible to support the case where there are mipmaps because in that case the layout is very different. It could be good to make a similar change for Gen8 if we also change the layouting code to pick the qpitch value in a similar way. v2: Make the commit message and comments more convincing Reviewed-by: Ben Widawsky <[email protected]> Tested-by: Ben Widawsky <[email protected]>

| | | | | | | | | | | | | | | | | | | | | Jason noticed that shader_time was bumping the reference count on the gl_shader_program and gl_program structures, in code called during compilation. Not only were these never unreferenced, but it meant fragment shaders might be referenced twice (SIMD8 and SIMD16)...or only once. We don't actually need the programs. We just need their numeric ID and their language (GLSL/ARB/FF) or KHR_debug label. If there's a label, we have to strdup it since the underlying program could be deleted. To be fair, we're not exactly cleaning that up either, but we at least ralloc it out of the shader_time arrays, so if we ever bother cleaning those up, they'll go away properly.

* i965/fs: Use the source type when looking for UD negations in copy propJason Ekstrand2015-04-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There can be problems with floats and conditional modifiers when copy-propagating a negated UD source. The problem arises when a source modifier is applied to a UD value. In this case, a 33-bit representation is internally used. If you do the following: 1: mov foo:UD 7U 2: mov bar:UD -foo:UD 3: mov out:F bar:UD the out register will have the value (float)(unt32_t)-7 which is some very large floating-point number. However, if we allow copy-propagation of the second mov, we get 1: mov foo:UD 7U 3: mov out:f -bar:UD and, since the negation is computed in 33-bits, we get a value of -7.0f which is clearly not the same. This is a similar problem if the instruction has a conditional modifier where the 33-bit value is used in the comparison and not the 32-bit version. Previously, we checked the source to be copied for the negate and then checked the source being propagated to for the type. This isn't quite what we want because we are really just looking for negated UD sources. A check later in the file ensures that both ends of the propagate have the right type so it works. However, if we relax the restriction that both ends of the propagation have the same type, it ends up causing us to bail early in cases we don't want.
