* r300/compiler: Implement simple loop emulationTom Stellard2010-06-117-3/+233
| | | | | | | The loop emulation unrolls loops as may times as possbile while still keeping the shader program below the maximum instruction limit. At this point, there are no checks for constant conditionals. This is only enabled for fragment shaders.
* i965: Remove the surface key used to generate constant surfaces.Eric Anholt2010-06-113-62/+14
| | | | We had to fill out all that junk when using the cache, but no more.
* i965: Warning fixes from the i965-streaming merge.Eric Anholt2010-06-112-11/+0
|
* gallium/softpipe/draw: support samplers in geometry shadersZack Rusin2010-06-1111-5/+153
|
* tgsi: support 2d indirect addressingZack Rusin2010-06-115-18/+86
|
* i965: Use the state base address to avoid relocations.Eric Anholt2010-06-113-38/+23
| | | | | | | | This makes the binding table code simpler, and is required for gen6, which requires binding table addresses to be under 64k offset from the surface state base addr. No significant change in performance on firefox-talos-gfx.
* i965: GC the last two arguments to brw_cache_data.Eric Anholt2010-06-117-22/+12
| | | | | Now that the binding table is streamed indirect state, they were always NULL/0.
* i965: Remove brw_state_cache_bo_delete now that it's unused again.Eric Anholt2010-06-112-37/+0
|
* i965: Remove caching of surface state objects.Eric Anholt2010-06-118-288/+192
| | | | | | | | | | | It turns out that computing a 56 byte key to look up a 20-byte object out of a hash table was some sort of a bad idea. Whoops. before: [ # ] backend test min(s) median(s) stddev. count [ 0] gl firefox-talos-gfx 37.799 38.203 0.39% 6/6 after: [ 0] gl firefox-talos-gfx 34.761 34.784 0.17% 5/6
* i965: Convert the binding table to streamed indirect state.Eric Anholt2010-06-117-145/+131
| | | | | | | | | | | | | | | | | | | | | | | This slightly reduces reduces cairo-gl firefox-talos-gfx runtime on my Ironlake: before: [ # ] backend test min(s) median(s) stddev. count [ 0] gl firefox-talos-gfx 38.236 38.383 0.43% 5/6 after: [ 0] gl firefox-talos-gfx 37.799 38.203 0.39% 6/6 It turns out the cost of caching these objects and looking them up in the cache again is greater than the cost of just computing the object again, particularly when the overhead of having a separate BO to pin is removed. (Those that are paying close attention will note that this is a reversal of the path I was moving the driver in a couple of years ago. The major thing that has changed is that back then all state was recomputed when we wrapped the streaming state buffer, including recompiling our precious programs. Now, we're uncaching just the objects that are cheap to compute, and retaining caching of expensive objects)
* i965: Split constant buffer setup from its surface state/binding state.Eric Anholt2010-06-118-78/+79
| | | | This was bothering me when redoing the binding tables.
* i965: Add support for streaming indirect state rather than caching objects.Eric Anholt2010-06-115-1/+66
|
* i965: Set the CC VP state immediately on state change.Eric Anholt2010-06-117-12/+67
| | | | | | | | The cache lookup of these two little floats was .12% of total CPU time on firefox-talos-gfx because we did it any time commonly-changed state changed. On the other hand, updating the CC VP bo immediately whenver CC VP state changes is a .07% overhead due to putting a driver hoook in glEnable().
* i965: Update old comment about state cache sizing.Eric Anholt2010-06-111-2/+2
|
* i965: Move no_batch_wrap assertion out across the area we're trying to verify.Eric Anholt2010-06-111-5/+3
| | | | | It's more likely that we wrap badly in state setup than in the little primitive packet.
* i965: remove UseProgram driver callbackBrian Paul2010-06-101-10/+0
| | | | It just duplicated the default/core Mesa behaviour.
* st/egl: Do not build non-working driver combinations.Chia-I Wu2010-06-111-0/+6
| | | | | | The KMS backend requires a hardware pipe driver. Do not build egl_kms_swrast. Also, only build egl_fbdev_swrast for fbdev backend. It is a pure software backend.
* st/egl: Add fbdev backend.Chia-I Wu2010-06-113-6/+501
| | | | | The backend is pure software. It implements EGL_MESA_screen_surface extension, and is kept simple by only exporting the current mode.
* winsys: Add fbdev software winsys.Chia-I Wu2010-06-114-0/+298
| | | | | | This is a simple winsys that mmap()s the framebuffer device and memcpy()s the contents of display targets to the framebuffer device for displaying.

* i965: Add support for GL_ALPHA framebuffer objects.Eric Anholt2010-06-106-14/+85
|
* mesa: Allow GL_ALPHA FBOs with ARB_framebuffer_object.Eric Anholt2010-06-102-3/+7
| | | | Drivers still reject them today, but cairo would like to use these.
* swrast: When reading from a 0-bits r,g,b channel, return 0 not 1.Eric Anholt2010-06-101-3/+11
| | | | | | | It looks like we were reading a fractional value, multiplying by an enormous negative value, then stuffing that value into a bitfield assuming it was already clamped. This becomes relevant for GL_ALPHA or R/RG FBOs.
* intel: Use the blitter to upload TexSubImage data to busy textures.Eric Anholt2010-06-091-10/+67
| | | | | | | | | | | | | | This avoids many pipeline stalls in cairo-gl. [ # ] backend test min(s) median(s) stddev. count Before: [ 0] gl firefox-talos-gfx 36.799 36.851 2.34% 3/3 [ 0] gl firefox-talos-svg 33.429 35.360 3.46% 3/3 After: [ 0] gl firefox-talos-gfx 35.895 36.250 0.48% 3/3 [ 0] gl firefox-talos-svg 26.669 29.888 5.34% 3/3 This doesn't avoid all the pipeline stalls because the kernel reports !busy for buffers on the flushing list. That should be fixed in .36.
* i965: Avoid calloc/free in the CURBE upload process.Eric Anholt2010-06-095-20/+26
| | | | | | | In exchange we end up with an extra memcpy, but that seems better than calloc/free. Each buffer is 4k maximum, and on the i965-streaming branch this allocation was showing up as the top entry in brw_validate_state profiling for cairo-gl.
* r300g: try harder to create a transfer objectMarek Olšák2010-06-091-7/+34
| | | | | | | I was told this wouldn't help to fix the FDO bug #28443, but still, it's a harmless last resort. Also, linear textures safely fallback to an unpipelined transfer here.
