From 2ac2ecdd6c407e6d731474572193326844571f5e Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 14 Mar 2016 13:57:07 +0100 Subject: nouveau: codegen: Add support for OpenCL global memory buffers Add support for OpenCL global memory buffers, note this has only been tested with regular load and stores and likely needs more work for e.g. atomic ops. Tested with piglet on a gf119 and a gk107: ./piglit run -o shader -t '.*arb_shader_storage_buffer_object.*' results/shader [9/9] pass: 9 / ./piglit run -o shader -t '.*arb_compute_shader.*' results/shader [20/20] skip: 4, pass: 16 | Signed-off-by: Hans de Goede Reviewed-by: Samuel Pitoiset --- src/gallium/drivers/nouveau/codegen/nv50_ir_from_tgsi.cpp | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) (limited to 'src') diff --git a/src/gallium/drivers/nouveau/codegen/nv50_ir_from_tgsi.cpp b/src/gallium/drivers/nouveau/codegen/nv50_ir_from_tgsi.cpp index 0fa6cc4278e..557608ee977 100644 --- a/src/gallium/drivers/nouveau/codegen/nv50_ir_from_tgsi.cpp +++ b/src/gallium/drivers/nouveau/codegen/nv50_ir_from_tgsi.cpp @@ -1289,7 +1289,9 @@ bool Source::scanInstruction(const struct tgsi_full_instruction *inst) if (dst.isIndirect(0)) indirectTempArrays.insert(dst.getArrayId()); } else - if (dst.getFile() == TGSI_FILE_BUFFER) { + if (dst.getFile() == TGSI_FILE_BUFFER || + (dst.getFile() == TGSI_FILE_MEMORY && + memoryFiles[dst.getIndex(0)].mem_type == TGSI_MEMORY_TYPE_GLOBAL)) { info->io.globalAccess |= 0x2; } } @@ -1300,7 +1302,9 @@ bool Source::scanInstruction(const struct tgsi_full_instruction *inst) if (src.isIndirect(0)) indirectTempArrays.insert(src.getArrayId()); } else - if (src.getFile() == TGSI_FILE_BUFFER) { + if (src.getFile() == TGSI_FILE_BUFFER || + (src.getFile() == TGSI_FILE_MEMORY && + memoryFiles[src.getIndex(0)].mem_type == TGSI_MEMORY_TYPE_GLOBAL)) { info->io.globalAccess |= (insn.getOpcode() == TGSI_OPCODE_LOAD) ? 0x1 : 0x2; } else @@ -1534,6 +1538,10 @@ Converter::makeSym(uint tgsiFile, int fileIdx, int idx, int c, uint32_t address) if (tgsiFile == TGSI_FILE_MEMORY) { switch (code->memoryFiles[fileIdx].mem_type) { + case TGSI_MEMORY_TYPE_GLOBAL: + /* No-op this is the default for TGSI_FILE_MEMORY */ + sym->setFile(FILE_MEMORY_GLOBAL); + break; case TGSI_MEMORY_TYPE_SHARED: sym->setFile(FILE_MEMORY_SHARED); break; -- cgit v1.2.3
