* etnaviv: remove number of pixel pipes validationChristian Gmeiner2017-02-211-10/+0
| | | | | | | | | | | | | This validation was added before the etnaviv drm driver landed in the linux kernel. Due some pre-merge API changes we had to fix-up this value but with a mainline kernel this is not a problem anymore. Lets remove that validation which also gets rid of problem caught by Coverity, reported to me by imirkin.

| | | | | | | | | | | In case ctx->stream == NULL the fail label gets executed where pctx gets dereferenced - too bad pctx is NULL in that case. Caught by Coverity, reported to me by imirkin.

* gallium: set pipe_context uploaders in drivers (v3)Marek Olšák2017-02-141-0/+8
| | | | | | | | | | | | | | | Notes: - make sure the default size is large enough to handle all state trackers - pipe wrappers don't receive transfer calls from stream_uploader, because pipe_context::stream_uploader points directly to the underlying driver's stream_uploader (to keep it simple for now) v2: add error handling to nv50, nvc0, noop v3: set const_uploader Reviewed-by: Nicolai Hähnle <[email protected]> Tested-by: Edmondo Tommasina <[email protected]> (v1) Tested-by: Charmaine Lee <[email protected]>
* etnaviv: Set shader instruction area correctly for GC3000Wladimir J. van der Laan2017-02-121-5/+21
| | | | | | | | | | | | | - Use the same instruction area on GC3000 as the Vivante driver. This allows the same number of instructions on GC3000 as GC2000 instead of half. - Makes sure that the "PE to FE" stall before updating the shader code or constants is hit (which is conditional on vs_offset > 0x4000). This is necessary on GC3000 too, it increases stability. Signed-off-by: Wladimir J. van der Laan <[email protected]> Reviewed-by: Christian Gmeiner <[email protected]>

* gallium: add separate PIPE_CAP_INT64_DIVMODIlia Mirkin2017-02-091-0/+1
| | | | | | | | | | | Nouveau does not currently have logic to implement this as a library function. Even though such a library could be written, there's no big advantage to do it that way for now given that int64 is a very uncommon use-case. Allow a driver to expose INT64 without supporting division and modulo operations. Signed-off-by: Ilia Mirkin <[email protected]> Reviewed-by: Nicolai Hähnle <[email protected]>
* gallium: turn PIPE_SHADER_CAP_DOUBLES into a screen capabilityNicolai Hähnle2017-02-021-1/+1
| | | | | | | | | | | | | | | | | | | Make the cap consistent with PIPE_CAP_INT64. Aside from the hypothetical case of using draw for vertex shaders (and actually caring about doubles...), every implementation supports doubles either nowhere or everywhere. Also, st/mesa didn't even check the cap correctly in all supported shader stages. While at it, add a missing LLVM version check for 64-bit integers in radeonsi. This is conservative: judging by the log, LLVM 3.8 might be sufficient, but there are probably bugs that have been fixed since then. v2: fix clover (Marek) Reviewed-by: Marek Olšák <[email protected]>
* etnaviv: Set SE.CLIP registers, add margins for scissor/clip registersWladimir J. van der Laan2017-01-313-20/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | This fixes rendering of full-screen quads (and other screen-filling geometry, e.g. ioquake3 walls up-close) on gc3000. It should be a no-op on other hardware. - It looks like SE_CLIP registers were not set at all. I'm amazed that rendering worked without them. Emit them to avoid issues on gc3000. - Define constants ETNA_SE_SCISSOR_MARGIN_RIGHT (0x1119) ETNA_SE_SCISSOR_MARGIN_BOTTOM (0x1111) ETNA_SE_CLIP_MARGIN_RIGHT (0xffff) ETNA_SE_CLIP_MARGIN_BOTTOM (0xffff) These demarcate the margin (fixp16) between the computed sizes and the value sent to the chip. I have set these to the numbers used by the Vivante driver for gc2000. I am not sure whether any old hardware was relying on the old numbers, or whether those were just a guess. But if so, these need to be moved to the _specs structure. CC: <[email protected]> Signed-off-by: Wladimir J. van der Laan <[email protected]> Acked-by: Christian Gmeiner <[email protected]>
* etnaviv: Generate new sin/cos instructions on GC3000Wladimir J. van der Laan2017-01-313-1/+40
| | | | | | | | | | | | | | | | | | | | | Shaders using sin/cos instructions were not working on GC3000. The reason for this turns out to be that these chips implement sin/cos in a different way (but using the same opcodes): - Need their input scaled by 1/pi instead of 2/pi. - Output an x and y component, which need to be multiplied to get the result. - tex_amode needs to be set to 1. Add a new bit to the compiler specs and generate these instructions as necessary.

* etnaviv: Cannot render to rb-swapped formatsWladimir J. van der Laan2017-01-311-2/+5
| | | | | | | | | | | | | | Exposing rb swapped (or other swizzled) formats for rendering would involve swizzing in the pixel shader. This is not the case at the moment, so reject requests for creating such surfaces. (GPUs that need an extra resolve step anyway due to multiple pixel pipes, such as gc2000, might also do this swap in the resolve operation. But this would be tricky to keep track of) CC: <[email protected]> Signed-off-by: Wladimir J. van der Laan <[email protected]> Acked-by: Christian Gmeiner <[email protected]>
