* i965: clip: Add a function to determine whether a vert_result is in use.Paul Berry2011-09-063-9/+22
| | | | | | | | Previously we would examine the offset[] array (since an offset of 0 meant "not in use"). This paves the way for removing the offset[] array. Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | | The offsets within the VUE of HPOS and NDC are needed only in a few auxiliary clipping functions. This patch moves computation of those offsets into the functions that need them, and does the computation using the VUE map. Reviewed-by: Eric Anholt <[email protected]>

* i965: SF: New implementation of get_attr_override using the VUE map.Paul Berry2011-09-063-47/+78
| | | | | | | | This patch changes get_attr_override() (which computes the relationship between vertex shader outputs and fragment shader inputs) to use the VUE map. Reviewed-by: Eric Anholt <[email protected]>
* i965: SF: Remove unnecessary variables.Paul Berry2011-09-062-6/+2
| | | | | | | | | | This patch removes the variables nr_attrs and nr_setup_attrs, whose purpose is now being served by the VUE map. nr_attr_regs and nr_setup_regs are still needed, however they are now computed using the VUE map rather than by counting the number of vertex shader outputs (which caused subtle bugs when gl_PointSize was written).

* i965: SF: Stop using nr_setup_attrs in compute_masks.Paul Berry2011-09-061-1/+1
| | | | | | | | Previously, the SF used nr_setup_attrs to determine whether it was looking at the last element of the VUE. Changed this code to use the VUE map. Reviewed-by: Eric Anholt <[email protected]>
* i965: SF: Remove attr_to_idx and idx_to_attr.Paul Berry2011-09-062-13/+1
| | | | | | | | These data structures were serving the same purpose as the VUE map, but were buggy. Now that the code has been transitioned to use the VUE map, they are not needed. Reviewed-by: Eric Anholt <[email protected]>
* i965: SF: Change calculate_masks to use the VUE map.Paul Berry2011-09-061-4/+4
| | | | | | | | Previously, SF code used the idx_to_attr[] array to compute the location of entries in the VUE map. This array didn't properly account for gl_PointSize. Now we use the VUE map directly. Reviewed-by: Eric Anholt <[email protected]>
* 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.

* i965: SF: change get_vert_attr to use the VUE map, and rename it.Paul Berry2011-09-061-9/+14
| | | | | | | | | | | | 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. This fixes a bug on pre-Gen6 wherein the back side of a triangle would be rendered incorrectyl if the vertex shader wrote to gl_PointSize. Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | This patch moves the computation of the SF URB entry read offset from upload_sf_unit() to its own function, so that it can be re-used when creating the gen4-5 SF program. Reviewed-by: Eric Anholt <[email protected]>
* i965: new VS: Compute urb entry size based on the VUE map.Paul Berry2011-09-061-7/+2
| | | | | | | | Previously, the new VS backend computed the size of the URB entry by counting the number of MRFs used in emitting the URB entry. Now it just gets it straight from the VUE map. Reviewed-by: Eric Anholt <[email protected]>
* i965: new VS: Clarify comments about max_usable_mrf and add an assertion.Paul Berry2011-09-061-4/+8
| | | | | | | | | | 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). This patch adds an assertion to confirm that this is the case, and moves the comment to this effect to be near the assertion. Reviewed-by: Eric Anholt <[email protected]>
* i965: new VS: use the VUE map to write out vertex attributes.Paul Berry2011-09-062-113/+55
| | | | | | | | | | | | | Previously, the new VS backend used two functions, emit_vue_header_gen6() and emit_vue_header_gen4() to emit the fixed parts of the VUE, and then a pair of carefully-constructed loops to emit the rest of the VUE, leaving out the parts that were already emitted as part of the header. This patch changes the new VS backend to use the VUE map to emit the entire VUE. Reviewed-by: Eric Anholt <[email protected]>

* i965: new VS: Use output_reg[] to find NDC and HPOS registers.Paul Berry2011-09-062-8/+14
| | | | | | | | | Previously, emit_vue_header_gen4() used local variables to keep track of which registers were storing the NDC and HPOS. This patch uses the output_reg[] array instead, so that the code that manipulates NDC and HPOS can be more easily refactored. Reviewed-by: Eric Anholt <[email protected]>
* 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]>

* i965: Write code to compute a VUE map.Paul Berry2011-09-062-0/+168
| | | | | | | | | | | Several places in the i965 code make implicit assumptions about the structure of data in the VUE (vertex URB entry). This patch adds a function, brw_compute_vue_map(), which computes the structure of the VUE explicitly. Future patches will modify the rest of the driver to use the explicitly computed map rather than rely on implicit assumptions about it. Reviewed-by: Eric Anholt <[email protected]>
* Refactor code that converts between gl_vert_result and gl_frag_attrib.Paul Berry2011-09-065-41/+52
| | | | | | | | | | | | Previously, this conversion was duplicated in several places in the i965 driver. This patch moves it to a common location in mtypes.h, near the declaration of gl_vert_result and gl_frag_attrib. I've also added comments to remind us that we may need to revisit the conversion code when adding elements to gl_vert_result and gl_frag_attrib. Reviewed-by: Eric Anholt <[email protected]>
