* i965/vs: Rework binding table size calculation.Kenneth Graunke2013-08-195-16/+20
| | | | | | | | | | | | | | | | | | | | | | Unlike the FS, the VS backend already computed the binding table size. However, it did so poorly: after compilation, it looked to see if any pull constants/textures/UBOs were in use, and set num_surfaces to the maximum surface index for that category. If the VS only used a single texture or UBO, this overcounted by quite a bit. The shader time surface was also noted at state upload time (during drawing), not at compile time, which is inefficient. I believe it also had an off by one error. This patch computes it accurately, while also simplifying the code. It also renames num_surfaces to binding_table_size, since num_surfaces wasn't actually the number of surfaces used. For example, a VS that used one UBO and no other surfaces would have set num_surfaces to SURF_INDEX_VS_UBO(1) == 18, rather than 1. A bit of a misnomer there.

* i965/fs: Make the FS binding table as small as possible.Kenneth Graunke2013-08-191-6/+5
| | | | | | | | | | | | | | Computing the minimum size was easy, and done at compile-time for no extra overhead here. Making the binding table smaller wastes less batch space. Adding the CACHE_NEW_WM_PROG dirty bit isn't strictly necessary, since other atoms depend on it and flag BRW_NEW_SURFACES. However, it's best to add it for clarity and safety. It shouldn't add any new overhead. v2: Use binding_table_size, rather than max_surface_index. Signed-off-by: Kenneth Graunke <[email protected]>
* i965/fs: Track the binding table size in brw_wm_prog_data.Kenneth Graunke2013-08-193-0/+27
| | | | | | | | | | | | | | | By tracking the maximum surface index used by the shader, we know just how small we can make the binding table. Since it depends entirely on the shader program, we can just compute it once at compile time, rather than at binding table emit time (which happens during drawing). v2: Store binding_table_size, rather than max_surface_index, for consistency with the VS (which needs to be able to represent 0 surfaces).

* i965: Use SURF_INDEX_DRAW() for drawbuffer binding table indices.Kenneth Graunke2013-08-194-17/+15
| | | | | | | | | | | | | | | | | | | | | SURF_INDEX_DRAW() has been the identity function since the dawn of time, and both the shader code and binding table upload code relied on that, simply using X rather than SURF_INDEX_DRAW(X). Even if that continues to be true, using the macro clarifies the code. The comment about draw buffers needing to be first in order for headerless render target writes to work turned out to be wrong; with this change, SURF_INDEX_DRAW can be changed to arbitrary indices and everything continues working. The confusion was over the "Render Target Index" field in the FB write message header. If it were a binding table index, then RT 0 would have to be at index 0 for headerless FB writes to work. However, it's actually an index into the blend state table, so there's no problem. Signed-off-by: Kenneth Graunke <[email protected]> Cc: Paul Berry <[email protected]>

| | | | | | | | | | | | | | Also upload separate sampler default/texture border color entries. At the moment, this is completely idiotic: both tables contain exactly the same contents, so we're simply wasting batch space and CPU time. However, soon we'll only upload data for textures actually /used/ in a particular stage, which will usually make the VS table empty and very likely eliminate all redundancy.

| | | | | | | | | | | | | Excluding the existing liveout bits is a deviation from the textbook algorithm. The reason for doing so was to determine if the value changed, which means the fixed-point algorithm needs to run for another iteration.

* i965/fs: Separate the updating of liveout/livein.Kenneth Graunke2013-08-191-3/+8
| | | | | | | | | | | | | | | | | | | | | | To compute the actual liveout/livein data flow values, we start with some initial values and apply a fixed-point algorithm until they settle. Previously, we iterated through all blocks, updating both liveout and livein together in one pass. This is awkward, since computing livein for a block requires knowing liveout for all parent blocks. Not all of those parent blocks may have been processed yet. This patch separates the two. First, we update liveout for all blocks. At iteration N of the fixed-point algorithm, this uses livein values from iteration N-1. Secondly, we update livein for all blocks. At step N, this uses the liveout information we just computed (in step N). This ensures each computation has a consistent picture of the data, rather than seeing an random mix of data from steps N-1 and N depending on the order of the blocks in the CFG data structure.
