2016-04-26softpipe: add support for compute shaders.HEADmasterDave Airlie7-3/+325
This enables ARB_compute_shader on softpipe. I've only tested this with piglit so far, and I hopefully plan on integrating it with my vulkan work. I'll get to testing it with deqp more later. The basic premise is to create up to 1024 restartable TGSI machines, and execute workgroups of those machines. v1.1: free machines. Signed-off-by: Dave Airlie <airlied@redhat.com>
2016-04-26tgsi/exec: misc fixes for compute shaders.Dave Airlie1-1/+4
We want to use the SysSemanticToIndex to tell if we've seen the semantics at all. Also add semantic swizzle support. Signed-off-by: Dave Airlie <airlied@redhat.com>
2016-04-26tgsi/exec: implement restartable machine.Dave Airlie2-17/+29
This lets us restart the machine at a PC value, and exits the machine when we hit a barrier. Compute shaders will then execute all the threads up to the barrier, then restart the machines after the barrier once all are done. Signed-off-by: Dave Airlie <airlied@redhat.com>
2016-04-26tgsi/exec: make inputs/outputs optional for compute shaders.Dave Airlie1-19/+24
compute shaders don't need input/outputs so don't bother allocating memory for these. Signed-off-by: Dave Airlie <airlied@redhat.com>
2016-04-26tgsi/exec: implement load/store/atomic on MEMORY.Dave Airlie2-3/+110
This implements basic load/store/atomic ops on MEMORY types for compute shaders. TODO: finish off atomic ops. Signed-off-by: Dave Airlie <airlied@redhat.com>
2016-04-26tgsi/exec: split out setting up masks to separate functionDave Airlie1-9/+14
This is just a cleanup that will make later changes easier to make. Signed-off-by: Dave Airlie <airlied@redhat.com>
2016-04-26tgsi: accept a starting PC value for exec machine.Dave Airlie5-5/+5
This will be used later to restart barriered execution threads in compute, for now we just want to change the API. Signed-off-by: Dave Airlie <airlied@redhat.com>
2016-04-26tgsi/exec: fix system value handling.Dave Airlie1-3/+5
a) SysSemanticToIndex needs to be indexed with the semantic name not the decl->Declaration.Semantic. b) doing this in run is too late, as the mappings are all setup prior to run in the execs. Signed-off-by: Dave Airlie <airlied@redhat.com>
2016-04-26tgsi: move to using vector for system values.Dave Airlie4-7/+7
For compute support some of the system values are .xyz types, so move to using a vector instead of a single channel. Signed-off-by: Dave Airlie <airlied@redhat.com>

2016-04-26tgsi: pass a shader type to the machine create and clean up.Dave Airlie5-15/+15
There was definitely bugs here mixing up the PIPE_ and TGSI_ defines, hopefully they didn't cause any problems, since mostly it was special cases for GEOMETRY. This clarifies at shader machine create what type of shader this machine will execute. This is needed also for compute shaders where we don't want to allocate inputs/outputs.

2016-04-26gallium/tgsi: move tgsi_exec.h header out of draw_context.hDave Airlie2-1/+1
It gets annoying that changing the tgsi exec rebuilds the state tracker unnecessarily. Putting this include into draw_gs.h which uses it causes a lot less rebuilds. Reviewed-by: Brian Paul <brianp@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2016-04-26gallivm: make sampling more robust against bogus coordinatesRoland Scheidegger3-13/+43
Some cases (especially these using fract for coord wrapping) did not handle NaNs (or Infs) correctly - the following code assumed the fract result could not be outside [0,1], but if the input is a NaN (or +-Inf) the fract result was NaN - which then could produce out-of-bound offsets. (Note that the explicit NaN behavior changes for min/max on x86 sse don't result in actual changes in the generated jit code, but may on other architectures. Found by looking through all the wrap functions.) This fixes https://bugs.freedesktop.org/show_bug.cgi?id=94955 No piglit changes.

2016-04-25freedreno/ir3: convert over to rallocRob Clark2-40/+6
The home-grown heap scheme (which is ultra-simple but probably not good to always allocate and memset such a chunk of memory up front) was a remnant of fdre (where the ir originally came from). But since we have ralloc in mesa, lets just use that instead. Signed-off-by: Rob Clark <robclark@freedesktop.org>

2016-04-25svga: eliminiate unnecessary constant buffer updatesCharmaine Lee3-2/+23
Currently if the texture binding is changed, emit_fs_consts() is triggered to update texture scaling factor for rectangle texture or texture buffer size in the constant buffer. But the update is only relevant if the texture binding includes a rectangle texture or a texture buffer. To eliminate the unnecessary constant buffer updates due to other texture binding changes, a new flag SVGA_NEW_TEXTURE_CONSTS will be used to trigger fragment shader constant buffer update when a rectangle texture or a texture buffer is bound. With this patch, the number of constant buffer updates in Lightsmark2008 reduces from hundreds per frame to about 28 per frame. Reviewed-by: Brian Paul <brianp@vmware.com>
2016-04-25svga: mark the texture dirty for write transfer map onlyCharmaine Lee1-2/+4

2016-04-25svga: minimize surface flushCharmaine Lee2-15/+85
Currently, we always do a surface flush when we try to establish a synchronized write transfer map. But if the subresource has not been modified, we can skip the surface flush. In other words, we only need to do a surface flush if the to-be-mapped subresource has been modified in this command buffer. With this patch, lightsmark2008 shows about 15% performance improvement.
