| | | | | | | | This reverts commit 5ceadd29b0af835d741bcf09b9622c628e549ae6. I rebased and apparently failed to build test. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=75355
* i965/fs: Drop the emit(fs_inst) overload.Kenneth Graunke2014-02-213-25/+17
| | | | | | | | | | | | | | | | | | | | Using this emit function implicitly creates three copies, which is pointlessly inefficient. 1. Code creates the original instruction. 2. Calling emit(fs_inst) copies it into the function. 3. It then allocates a new fs_inst and copies it into that. The second could be eliminated by changing the signature to fs_inst(const fs_inst &) but that wouldn't eliminate the third. Making callers heap allocate the instruction and call emit(fs_inst *) allows us to just use the original one, with no extra copies, and isn't much more of a burden.

* i965: Mark brw_reg_type and register_file enums as PACKED.Matt Turner2014-02-212-2/+4
| | | | | | | | | | | | | | | | | | | The C99 spec says the type of an enum is implementation defined (but can be char, signed int, or unsigned int). gcc appears to always give enums four bytes, even when they can fit in less. It does so because this is what other compilers seem to do [0] and therefore to maintain ABI compatibility with them. gcc has an -fshort-enum flag that tells the compiler to use only as much space as needed for an enum. Adding __attribute__((__packed__)) to an enum definition has the same behavior, but on a per-enum basis. brw_reg_type and register_file are not part of the ABI, so we can safely mark them as PACKED so that they'll take only a byte, rather than four.

Without hardware contexts, we rely on this state being uploaded via atoms that subscribe to the BRW_NEW_CONTEXT bit. Commit 46d3c2bf4ddd227193b98861f1e632498fe547d8 accidentally moved the call to brw_init_state() before creating a hardware context. This meant brw_upload_initial_gpu_state would always early return. Except on Gen6+, we stopped uploading the initial GPU state via state atoms, so it never happened. Fixes a regression since 46d3c2bf4ddd227193b98861f1e632498fe547d8.

* i965/fs: Implement scratch read/write support for Broadwell.Kenneth Graunke2014-02-201-9/+109
| | | | | | | | | | | | | | To make sure that both the Gen4 and Gen7 style messages work, I initially disabled the SHADER_OPCODE_GEN7_SCRATCH_READ optimization, ran Piglit, re-enabled it, and ran Piglit again. Both worked fine. Fixes 40 Piglit tests (most of the varying-packing category). v2: Move num_regs assertion from gen8_fs_generator to gen8_set_dp_scratch_message() (suggested by Eric).
