* i965/tiled_memcpy: Add tiled-to-linear pathsSisinty Sasmita Patra2015-01-262-0/+281
| | | | | | | | | | | | | | | | | This commit addes tiled copy functions for coping from tiled memory to linear memory. These are very similar to the existing linear-to-tiled paths. v2: Jason Ekstrand <[email protected]> - New commit message - Various whitespace fixes - Added ptrdiff_t casts as done in commit 225a09790 v3: Jason Ekstrand <[email protected]> - Fixed a comment Signed-off-by: Jason Ekstrand <[email protected]> Reviewed-by: Chad Versace <[email protected]>
* i965: Refactor tiled memcpy functions and move them into their own fileSisinty Sasmita Patra2015-01-264-392/+506
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit refactors the tiled_memcpy code in intel_tex_subimage.c and moves it into its own file intel_tiled_memcpy files. Also, xtile_copy and ytile_copy are renamed to linear_to_xtiled and linear_to_ytiled respectively. The *_faster functions are similarly renamed. There was also a bit of logic to select between the the libc provided memcpy function and our custom memcpy that does an RGBA -> BGRA swizzle. This was moved into an intel_get_memcpy function so that rgba8_copy can live (and be inlined) in intel_tiled_memcpy.c. v2: Jason Ekstrand <[email protected]> - Better commit message - Fix up the copyright on the intel_tiled_memcpy files - Various whitespace fixes - Moved a bunch of stuff that did not need to be exposed from intel_tiled_memcpy.h to intel_tiled_memcpy.c - Added proper documentation for intel_get_memcpy - Incorperated the ptrdiff_t tweaks from commit 225a09790 v3: Jason Ekstrand <[email protected]> - Fixed a comment - Move the tile size constants into the .c file Signed-off-by: Jason Ekstrand <[email protected]> Reviewed-by: Chad Versace <[email protected]>

* i965: Handle CMP.nz ... 0 and MOV.nz similarly in cmod propagation.Kenneth Graunke2015-01-261-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | "MOV.nz null src" and "CMP.nz null src 0" are equivalent instructions. Previously, we deleted MOV.nz instructions when the instruction generating the MOV's source also wrote the flag register (as the flag register already contains the desired value). However, we wouldn't delete CMP.nz instructions that served the same purpose. We also didn't attempt true cmod propagation on MOV.nz instructions, while we would for the equivalent CMP.nz form. This patch fixes both limitations, treating both forms equally. CMP.nz instructions will now be deleted (helping the NIR backend), and MOV.nz instructions will have their .nz propagated. No changes in shader-db without NIR. With NIR, total instructions in shared programs: 6006153 -> 5969364 (-0.61%) instructions in affected programs: 2087139 -> 2050350 (-1.76%) helped: 10704 HURT: 0 GAINED: 2 LOST: 2 Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Matt Turner <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | Add a required field to the Opcode class, const_expr, that contains an expression or statement that computes the result of the opcode given known constant inputs. Then take those const_expr's and expand them into a function that takes an opcode and an array of constant inputs and spits out the constant result. This means that when adding opcodes, there's one less place to update, and almost all the opcodes are self-documenting since the information on how to compute the result is right next to the definition.

* nir: use Python to autogenerate opcode informationConnor Abbott2015-01-249-401/+479
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before, we used a system where a file, nir_opcodes.h, defined some macros that were included to generate the enum values and the nir_op_infos structure. This worked pretty well, but for development the error messages were never very useful, Python tools couldn't understand the opcode list, and it was difficult to use nir_opcodes.h to do other things like autogenerate a builder API. Now, we store opcode information in nir_opcodes.py, and we have nir_opcodes_c.py to generate the old nir_opcodes.c and nir_opcodes_h.py to generate nir_opcodes.h, which contains all the enum names and gets included into nir.h like before. In addition to solving the above problems, using Python and Mako to generate everything means that it's much easier to add keep information centralized as we add new things like constant propagation that require per-opcode information. v2: - make Opcode derive from object (Dylan) - don't use assert like it's a function (Dylan) - style fixes for fnoise, use xrange (Dylan) - use iterkeys() in nir_opcodes_h.py (Dylan) - use pydoc-style comments (Jason) - don't make fmin/fmax commutative and associative yet (Jason) Signed-off-by: Connor Abbott <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]> v3 Jason Ekstrand <[email protected]> - Alphabetize source file lists - Generate nir_opcodes.h in the builddir instead of the source dir - Include $(builddir)/src/glsl/nir in the i965 build - Rework nir_opcodes.h generation so it generates a complete header file instead of one that has to be embedded inside an enum declaration
