* radeonsi: assume ClipDistance usage mask is always 0xfMarek Olšák2014-10-122-8/+2
| | | | | | | | | | | | No code in Mesa sets the usage mask to any other value. The final mask is AND'ed with enable bits from the rasterizer state anyway. If somebody implements setting usage masks in st/mesa, we can use tgsi_shader_info to get it more easily. This is a prerequisite for the following commit.

* glsl: improve accuracy of atan()Erik Faye-Lund2014-10-101-10/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our current atan()-approximation is pretty inaccurate at 1.0, so let's try to improve the situation by doing a direct approximation without going through atan. This new implementation uses an 11th degree polynomial to approximate atan in the [-1..1] range, and the following identitiy to reduce the entire range to [-1..1]: atan(x) = 0.5 * pi * sign(x) - atan(1.0 / x) This range-reduction idea is taken from the paper "Fast computation of Arctangent Functions for Embedded Applications: A Comparative Analysis" (Ukil et al. 2011). The polynomial that approximates atan(x) is: x * 0.9999793128310355 - x^3 * 0.3326756418091246 + x^5 * 0.1938924977115610 - x^7 * 0.1173503194786851 + x^9 * 0.0536813784310406 - x^11 * 0.0121323213173444 This polynomial was found with the following GNU Octave script: x = linspace(0, 1); y = atan(x); n = [1, 3, 5, 7, 9, 11]; format long; polyfitc(x, y, n) The polyfitc function is not built-in, but too long to include here.

* vc4: Prevent copy propagating out the MOVs from r4.Eric Anholt2014-10-091-1/+11
| | | | | | | | | Copy propagating these might result in reading the r4 after some other instruction has written r4. Just prevent all copy propagation of this for now. Fixes bad rendering with upcoming indirect register access support, where the copy propagation was consistently happening across another read.
* vc4: Split the coordinate shader to its own vc4_compiled_shader.Eric Anholt2014-10-093-89/+54
| | | | | | | | | | | Merging VS and CS into the same struct wasn't winning us anything except for not allocating a separate BO (but if we want to pack programs into BOs, we should pack not just those 2 programs together). What it was getting us was a bunch of code duplication about hash table lookups and propagating vc4_compile contents into a vc4_compiled_shader. I was about to make the situation worse with indirect uniform buffer access.
* vc4: Add #defines for the texture uniform fields.Eric Anholt2014-10-092-19/+113
| | | | | | I wanted to make another set of texture uploads for handling reladdr constants, and duplicating all the bitshifting looked like a terrible idea. In the process, this fixes a swap of the s/t texture wrap modes.
* vc4: Initialize undefined temporaries to 0.Eric Anholt2014-10-091-1/+6
| | | | | | | | | | Under the simulator, reading registers before writing them triggers an assertion failure. c->undef gets treated as r0, which will usually be written, but not if it's used in the first instruction. We should definitely not be aborting in this case, and return some sort of undefined value instead. Fixes glsl-user-varying-ff.
* i965: Skip uploading border color when unnecessary.Kenneth Graunke2014-10-091-2/+20
| | | | | | | | | | | | | | The border color is only needed when using the GL_CLAMP_TO_BORDER or (deprecated) GL_CLAMP wrap modes; all others ignore it, including the common GL_CLAMP_TO_EDGE and GL_REPEAT wrap modes. In those cases, we can skip uploading it entirely, saving a bit of space in the batchbuffer. Instead, we just point it at the start of the batch (offset 0); we have to program something, and that address is safe to read.

* i965: Use BDW_MOCS_PTE for renderbuffers.Kenneth Graunke2014-10-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Write-back caching cannot be used for buffers being scanned out by the display engine; surfaces used for scan-out must be write-through or uncached. I originally chose WT for render targets because it works in all cases. However, we really want to use write-back caching where possible, as it is more efficient. Most renderbuffers are not used for scanout - off-screen FBOs certainly are fine, and non-pageflipped backbuffers should be fine as well. So in most cases WB will work. However, we don't know what will be used for scan-out, so we instead simply use the PTE value specified by the kernel, as it knows these things. This matches our MOCS choice on Haswell. Fixes performance regressions since commit ee4484be3dc827cf15bcf109f5 in a microbenchmark (spotted by Eero Tamminen). Improves performance in GLBenchmark 2.7/EgyptHD by 7.44362% +/- 0.496939% (n=55) on a Broadwell GT2. Improves performance in a bunch of other microbenchmarks by ~15% or so.

| | | | | | | | | | | | | | Like BDW_MOCS_WB and BDW_MOCS_WT, this specifies that we want to use all three caches (L3, LLC, and eLLC where available), but leaves the LLC caching mode up to the kernel's page table entry. This allows the kernel to pick WB/WT/UC based on whether it's using a buffer for scanout.

| | | | | | | | | | | | | | The non-base NPOT levels are stored as POT-aligned images. We get that POT alignment by minifying the POT-aligned base level. This means that level strides are also POT aligned, so we have to tell the rendering mode config that our resource is larger than the actual requested area.

| | | | | | | | | | It's fairly easy, thanks to Rob Clark's lowering code. Fixes two-sided-lighting and 4 vertex-program-two-side testcases, while regressing 8 testcases that involve enabling two-sided color while only initializing one of the two colors in the VS. If you're enabling two sided color, it's of course expected that you really do set up both colors, so this is still an improvement (and when we set up a linker for TGSI, we'll hopefully fix those 8 fails).

The algorithm is similar to alpha-beta pruning on a minmax search, from the field of AI. This optimization pass can optimize min/max expressions where operands are min/max expressions. Such code can appear in shaders by itself, or as the result of clamp() or AMD_shader_trinary_minmax functions. This optimization pass improves the generated code for piglit's AMD_shader_trinary_minmax tests as follows: total instructions in shared programs: 75 -> 67 (-10.67%) instructions in affected programs: 60 -> 52 (-13.33%) GAINED: 0 LOST: 0 All tests (max3, min3, mid3) improved. A full shader-db run: total instructions in shared programs: 4293603 -> 4293575 (-0.00%) instructions in affected programs: 1188 -> 1160 (-2.36%) GAINED: 0 LOST: 0 Improvements happen in Guacamelee and Serious Sam 3. One shader from Dungeon Defenders is hurt by shader-db metrics (26 -> 28), because of dropping of a (constant float (0.00000)) operand, which was compiled to a saturate modifier. Version 2 by Iago Toral Quiroga <[email protected]>: Changes from review feedback: - Squashed various cosmetic changes sent by Matt Turner. - Make less_all_components return an enum rather than setting a class member. (Suggested by Mat Turner). Also, renamed it to compare_components. - Make less_all_components, smaller_constant and larger_constant static. (Suggested by Mat Turner) - Change mixmax_range to call its limits "low" and "high" instead of "range[0]" and "range[1]". (Suggested by Connor Abbot). - Use ir_builder swizzle helpers in swizzle_if_required(). (Suggested by Connor Abbot). - Make the logic more clearer by rearrenging the code and commenting. (Suggested by Connor Abbot). - Added comment to explain why we need to recurse twice. (Suggested by Connor Abbot). - If we cannot prune an expression, do not return early. Instead, attempt to prune its children. (Suggested by Connor Abbot). Other changes: - Instead of having a global "valid" visitor member, let the various functions that can determine this status return a boolean and check for its value to decide what to do in each case. This is more flexible and allows to recurse into children of parents that could not be prunned due to invalid ranges (so related to the last bullet in the review feedback). - Make sure we always check if a range is valid before working with it. Since any use of get_range, combine_range or range_intersection can invalidate a range we should check for this situation every time we use any of these functions. Version 3 by Iago Toral Quiroga <[email protected]>: Changes from review feedback: - Now we can make get_range, combine_range and range_intersection static too (suggested by Connor Abbot). - Do not return NULL when looking for the larger or greater constant into mixed vector constants. Instead, produce a new constant by doing a component-wise minmax. With this we can also remove of the validations when we call into these functions (suggested by Connor Abbot). - Add a comment explaining the meaning of the baserange argument in prune_expression (suggested by Connor Abbot). Other changes: - Eliminate minmax expressions operating on constant vectors with mixed values by resolving them. No piglit regressions observed with Version 3.
