| | | | | | | | | | | | | | EXT_shared_texture_palette This was also discussed at XDS 2010. However, actually making the change was delayed because several drivers still exposed these extensions to significant benefit (e.g., tdfx). Now that those drivers have been removed, this code can be removed as well. v2: A lot of bits that were missed in the previous patch have been removed.

* i965: Remove two_side_color from brw_compute_vue_map().Paul Berry2011-09-0612-22/+11
| | | | | | | | | | | Since we now lay out the VUE the same way regardless of whether two-sided color is enabled, brw_compute_vue_map() no longer needs to know whether two-sided color is enabled. This allows the two-sided color flag to be removed from the clip, GS, and VS keys, so that fewer GPU programs need to be recompiled when turning two-sided color on and off.

* i965: For GEN6+, always make front/back colors adjacent in VUE.Paul Berry2011-09-061-16/+12
| | | | | | | | | | | | | | | | | | When doing two-sided color on GEN6+, we use the SF unit's INPUTATTR_FACING mode to cause front colors to be used on front-facing triangles, and back colors to be used on back-facing triangles. This mode requires that the front and back colors be adjacent in the VUE. Previously, we would only place front and back colors adjacent in the VUE when two-sided color was enabled. Now we place them adjacent in the VUE whether two-sided color is enabled or not. (We still only swizzle the colors when two-sided color is enabled, so there should be no user-visible change). This simplifies the implementation of the VUE map and reduces the amount of code that is dependent on two-sided color mode. Reviewed-by: Eric Anholt <[email protected]>
* i965: GS: Use the VUE map to compute URB size.Paul Berry2011-09-062-17/+15
| | | | | | | | | | | The previous computation had two bugs: (a) it used a formula based on Gen5 for Gen6 and Gen7 as well. (b) it failed to account for the fact that PSIZ is stored in the VUE header. Fortunately, both bugs caused it to compute a URB size that was too large, which was benign. This patch computes the URB size directly from the VUE map, so it gets the result correct in all circumstances. Reviewed-by: Eric Anholt <[email protected]>

* i965: clip: Remove assumption about VUE header from brw_clip_interp_vertex()Paul Berry2011-09-061-5/+8
| | | | | | | | | | | Previously, brw_clip_interp_vertex() iterated only through the "non-header" elements of the VUE when performing interpolation (because header elements don't need interpolation). This code now refers exclusively to the VUE map to figure out which elements need interpolation, so that brw_clip_interp_vertex() doesn't need to know the header size.

* i965: SF: Change the flags that refer to "attr" to be based on gl_vert_result.Paul Berry2011-09-061-5/+6
| | | | | | | | | | | | Previously, some of the code in SF erroneously used bitfields based on the gl_frag_attrib enum when actually referring to vertex results. This worked, because coincidentally the particular enum values being used happened to match between gl_frag_attrib and gl_vert_result. But it was fragile, because a future change to either gl_vert_result or gl_frag_attrib would have made the enum values stop matching up. This patch switches the SF code to use the correct enum.

| | | | | | | | | | | | The new function, called get_vert_result(), uses the VUE map to find the register containing a given vertex attribute. Previously, we used the attr_to_idx[] array, which served the same purpose but didn't account for gl_PointSize correctly.

| | | | | | | | | | max_usable_mrf has been carefully set such that (max_usable_mrf - base_mrf) is a multiple of 2, so that an even number of VUE slots are emitted with each URB write (which Gen6 requires).

* i965: old VS: use the VUE map to compute the URB entry size.Paul Berry2011-09-062-25/+7
| | | | | | | | | | | | | | | | | | Previously, the old VS backend computed the URB entry size by adding the number of vertex shader outputs to the size of the URB header. This often produced a larger result than necessary, because some vertex shader outputs are stored in the header, so they were being double counted. This patch changes the old VS backend to compute the URB entry size directly from the number of slots in the VUE map. Note: there's a subtle change in that we no longer count header registers towards the size of the VF input. I believe this is correct, because the header is only emitted in the output of the VS stage--it is not present in the input. (As evidence for this, note that brw_vs_state.c sets urb_entry_read_offset to 0--it does not include space for the header as part of the VS input). Reviewed-by: Eric Anholt <[email protected]>
