* i965/fs: Move FB write default state mashing in a level.Kenneth Graunke2014-06-121-7/+7
| | | | | | | | | | We only need to alter the default state if we're emitting MOVs for header related fields. So, we can simply move the push/pop of state in to the if (header_present) block, bypassing it in the common case.

* i965: Fix Haswell discard regressions since Gen4-5 line AA fix.Kenneth Graunke2014-06-121-2/+7
| | | | | | | | | | | | | | | | In commit dc2d3a7f5c217a7cee92380fbf503924a9591bea, Iago accidentally moved fire_fb_write() above the brw_pop_insn_state(), which caused the SEND to lose its predication and change from WE_normal to WE_all. Haswell uses predicated SENDs for discards, so this broke Piglit's tests for discards. We want the Gen4-5 MOV to be uncompressed, unpredicated, and unmasked, but the actual FB write itself should respect those. So, pop state first, and force it again around the single MOV.

| | | | | | | | | | | | | | | | | | | Add Intel driver hook for glGetTexImage to accelerate the case of reading texture image into a PBO. This case gets huge performance gains by using GPU BLIT directly to PBO rather than GPU BLIT to temporary texture followed by memcpy. No regressions on Piglit tests with Intel driver.

When unrolling SIMD16 to multiple SIMD8 operations, we should take care not to apply sechalf to brw_null_reg for src1. Otherwise, we'd end up with BRW_ARF_NULL + 1 as the register number, and I'm not sure if that's valid.

| | | | | | | | | | | | | | | | | | | | Our existing functions, brw_math and brw_math2, had unclear roles: Gen4-5 used brw_math for both unary and binary math functions; it never used brw_math2. Since operands are already in message registers, this is reasonable. Gen6+ used brw_math for unary math functions, and brw_math2 for binary math functions, duplicating a lot of code. The only real difference was that brw_math used brw_null_reg() for src1. This patch improves brw_math2's assertions to allow both unary and binary operations, renames it to gen6_math(), and drops the Gen6+ code out of brw_math().

| | | | | | | | | | | | | | Thread switching on control flow instructions is a documented workaround for Gen4-5 errata. As far as I can tell, it hasn't been needed since Sandybridge. Thread switching is not free, so in theory this may help performance slightly. Flow control instructions with the "switch" flag cannot be compacted, so removing it will make these instructions compactable.
