* broadcom/vc4: Build the vc4_tiling_lt_neon.c with -mfpu=neon on ARM.Eric Anholt2017-08-154-7/+24
| | | | | | | | | | | | | If you don't pass this, the compiler refuses to compile the assembly for pre-v7 CPUs. This also keeps us from building identical, non-NEON code on aarch64 and x86.

* broadcom/vc4: Use the RA callback to improve register selection's choices.Eric Anholt2017-07-251-1/+52
| | | | | | | | | | | | | | | We simply pick r4 if available (anything else would force a MOV), then round-robin through accumulators (avoids physical regfile RAW delay slots), then round-robin through the physical regfile. The effect on instruction count is pretty impressive: total instructions in shared programs: 76563 -> 74526 (-2.66%) instructions in affected programs: 66463 -> 64426 (-3.06%) and we could probably do better with a little heuristic of "if we're going to choose a physical reg, and other operands of instructions using this as a src have the same physical regfile, then use the other regfile".

* vc4: Set shareable BOs as T tiled if possibleEric Anholt2017-07-124-13/+182
| | | | | | | | | | | | | | | | | | | | | | | | X11 and GL compositor performance on VC4 has been terrible because of our SHARED-usage buffers all being forced to linear. This swaps SHARED && !LINEAR buffers over to being tiled. This is an expected win for all GL compositors during rendering (a full copy of each shared texture per draw call), allows X11 to be used with decent performance without a GL compositor, and improves X11 windowed swapbuffers performance as well. It also halves the memory usage of shared buffers that get textured from. The only cost should be idle systems with a scanout-only buffer that isn't flagged as LINEAR, in which case the memory bandwidth cost of scanout goes up ~25%. This implements the EGL_EXT_image_dma_buf_import_modifiers extension, supporting the VC4 T_TILED modifier. v2: Added modifier support to resource creation/import, and advertisement (by daniels). v3: Fix old-kernel fallback path, fix compiler error and warnings, and comment touchups (by anholt).

* vc4: Introduce XML-based packet header generation like Intel's.Eric Anholt2017-06-301-1/+4
| | | | | | | | | | | | | | | I really liked this idea, as it should help with management of packet parsing tools like the CL dump.

* gallium: Add renderonly-based support for pl111+vc4.Eric Anholt2017-06-154-2/+54
| | | | | | | | | | | | | | | | | | | This follows the model of imx (display) and etnaviv (render): pl111 is a display-only device, so when asked to do GL for it, we see if we have a vc4 renderer, make the vc4 screen, and have vc4 call back to pl111 to do scanout allocations. The difference from etnaviv is that we share the same BO between vc4 and pl111, rather than having a vc4 bo and a pl11 bo and copies between the two. The only mismatch between their requirements is that vc4 requires 4-pixel (at 32bpp) stride alignment, while pl111 requires that stride match width. The kernel will reject any modesets to an incorrect stride, so the 3D driver doesn't need to worry about that. v2: Rebase on Android rework, drop unused include. v3: Fix another Android bug, from Rob Herring's build-testing.

* nir: Embed the shader_info in the nir_shader againJason Ekstrand2017-05-092-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit e1af20f18a86f52a9640faf2d4ff8a71b0a4fa9b changed the shader_info from being embedded into being just a pointer. The idea was that sharing the shader_info between NIR and GLSL would be easier if it were a pointer pointing to the same shader_info struct. This, however, has caused a few problems: 1) There are many things which generate NIR without GLSL. This means we have to support both NIR shaders which come from GLSL and ones that don't and need to have an info elsewhere. 2) The solution to (1) raises all sorts of ownership issues which have to be resolved with ralloc_parent checks. 3) Ever since 00620782c92100d77c660f9783504c6d80fa1d58, we've been using nir_gather_info to fill out the final shader_info. Thanks to cloning and the above ownership issues, the nir_shader::info may not point back to the gl_shader anymore and so we have to do a copy of the shader_info from NIR back to GLSL anyway. All of these issues go away if we just embed the shader_info in the nir_shader. There's a little downside of having to copy it back after calling nir_gather_info but, as explained above, we have to do that anyway.
