* llvmpipe: use vpkswss when dst is signedOded Gabbay2016-01-181-16/+15
| | | | | | | | | | | | | | | | | | | This patch fixes a bug when building a pack instruction. For POWER (altivec), in case the destination is signed and the src width is 32, we need to use vpkswss. The original code used vpkuwus, which emits an unsigned result. This fixes the following piglit tests on ppc64le: - spec@arb_color_buffer_float@gl_rgba8-drawpixels - shaders@glsl-fs-fogscale I've also corrected some coding style issues in the function. v2: Returned else statements to vmware style Signed-off-by: Oded Gabbay <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]>

| | | | | | | | | | | | | | | One of the oglconform tests was crashing here, and it was due to not cloning the actual parameters before creating the new call. This makes a call clone function that does the right things to make sure we clone all the needed info, and points the callee at it.

* i965/fs: Always set channel 2 of texture headers in some stagesJason Ekstrand2016-01-151-0/+8
| | | | | | | | | | | | | | | | In the vertex and fragment stages, the hardware is nice to us and leaves g0.2 zerod out for us so we can use it for headers. However, in compute, geometry, and tessellation stages, the hardware is not so nice. In particular, for compute shaders on BDW, the hardware places some debug bits in 23:15. As it happens, bit 15 is interpreted by the sampler as the alpha channel mask. This means that if you use a texturing instruction with a header in a compute shader, you may randomly get the alpha channel disabled. Since channel masks affect the return length of the sampler message, this can lead the GPU to expect a different mlen to the one you specified in the shader and this, in turn, hangs your GPU.

* llvmpipe: ditch additional ref counting for vertex/geometry sampler viewsRoland Scheidegger2016-01-154-46/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | The cleaning up was quite a performance hog (making pipe_resource_reference the number two in profilers on the vertex path, and 3rd overall, with its cousin pipe_reference_described not far behind) if there were lots of tiny draw calls (ipers). Now the reason was really that it was blindly calling this for all potential shader views (so 32 each for vs and gs) even though the app never touched a single one which could have been fixed, however I can't come up with a good reason why we refcount these. We've got references, of course, in the sampler views, which should be quite sufficient as we do all vertex and geometry shader execution fully synchronous. (Calling prepare_shader_sampling for all draw calls even if there were no changes looks quite suboptimal too, but generally we don't really expect vs/gs shader sampling to be used much with llvmpipe, and there's even an early exit if there aren't any views to avoid the "null loop" albeit it's now no longer always trying to loop through all 32 slots. Maybe improve another time...). Of course, if we manage to make vertex loads run asynchronously some day, we need references again, but adding that back would be the least of the problems... Also only set LP_NEW_SAMPLER_VIEW for fragment sampler views. Nothing on the vertex side depends on it (I suppose we'd really wanted a separate flag in any case). (Good for a 3% improvement or so in ipers under the right conditions.) Reviewed-by: Jose Fonseca <[email protected]>
* llvmpipe: fix "leaking" texturesRoland Scheidegger2016-01-152-2/+9
| | | | | | | | | | | | | | | | | | | | | This was not really a leak per se, but we were referencing the textures for longer than intended. If textures were set via llvmpipe_set_sampler_views() (for fs) and then picked up by lp_setup_set_fragment_sampler_views(), they were referenced in the setup state. However, the only way to unreference them was by replacing them with another texture, and not when the texture slot was replaced with a NULL sampler view. (They were then further also referenced by the scene too which might have additional minor side effects as we limit the memory size which is allowed to be referenced by a scene in a rather crude way.) Only setup destruction (at context destruction time) then finally would get rid of the references. Fix this by noting the number of textures the last time, and unreference things if the new view is NULL (avoiding having to unreference things always up to PIPE_MAX_SHADER_SAMPLER_VIEWS which would also have worked).
