[Nouveau] [PATCH mesa 1/6] tgsi_build: Fix return of uninitialized memory in tgsi_*_instruction_memory
tgsi_default_instruction_memory / tgsi_build_instruction_memory were
returning uninitialized memory for tgsi_instruction_memory.Texture and
tgsi_instruction_memory.Format. Note 0 means not set, and thus is a
correct default initializer for these.
Fixes: 3243b6fc97 ("tgsi: add Texture and Format to
tgsi_instruction_memory")

[Nouveau] [PATCH mesa 2/6] nouveau: codegen: Slightly refactor Source::scanInstruction() dst handling
Use the dst temp variable which was used in the TGSI_FILE_OUTPUT
case everywhere. This makes the code somewhat easier to reads
and helps avoiding going over 80 chars with upcoming changes.
This also brings the dst handling more in line with the src
handling.

[Nouveau] [PATCH mesa 3/6] nouveau: codegen: gk110: Make emitSTORE offset handling identical to emitLOAD
Make the store offset handling in CodeEmitterGK110::emitSTORE identical
to the one in CodeEmitterGK110::emitLOAD handling.
This is just a cleanup, it does not cause any functional changes.

[Nouveau] [PATCH mesa 4/6] nouveau: codegen: s/FILE_MEMORY_GLOBAL/FILE_MEMORY_BUFFER/
FILE_MEMORY_GLOBAL is currently only used for buffer handling, as we
do not yet have (opencl) global memory support. Global memory support
actually requires some different handling during lowering, so rename
FILE_MEMORY_GLOBAL to FILE_MEMORY_BUFFER to reflect that the current
code is for buffer handling, this will allow the later (re-)addition
of FILE_MEMORY_GLOBAL for regular global memory.

[Nouveau] [PATCH mesa 5/6] 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.

[Nouveau] [PATCH mesa 6/6] nouveau: codegen: Disable more old resource handling code
Commit c3083c7082 ("nv50/ir: add support for BUFFER accesses")
disabled /
commented out some of the old resource handling code, but not all of it.
Effectively all of it is dead already, if we ever enter the old code
paths in handeLOAD / handleSTORE / handleATOM we will get an exception
due to trying to access the now always zero-sized resources vector.
Make non buffer / memory file accesses not being supported in these
functions more explicit and comment out a whole bunch of dead code.
Also remove the magic file-indexe defines from the old resource code
from include/pipe/p_shader_tokens.h as those are no longer used now
(which is a good thing).

[Nouveau] [PATCH mesa 5/6] nouveau: codegen: Add support for OpenCL global memory buffers
Could you please get rid of the cosmetic changes (eg. the switch ones)? Because this doesn't really improve readability and in my opinion these changes should be eventually done in a separate patch. Other than that, this patch is : Reviewed-by: Samuel Pitoiset <samuel.pitoiset at gmail.com> Yes, this probably won't work as is for atomic operations but the lowering pass is already here, so it should be easy to make it work.

[Nouveau] [PATCH mesa 4/6] nouveau: codegen: s/FILE_MEMORY_GLOBAL/FILE_MEMORY_BUFFER/
This approach leads to the emitters needing to know about both global and buffer, even though at that point, they are identical. I was thinking that in the lowering logic, buffer would just get rewritten as global (with the offset added), thus not needing any change to the emitters. What do you think about such an approach? On Mar 16, 2016 2:24 AM, "Hans de Goede" <hdegoede at redhat.com> wrote:> FILE_MEMORY_GLOBAL is currently only used for buffer handling, as we > do not yet have (opencl) global memory support. Global memory support > actually requires some different handling during lowering, so rename > FILE_MEMORY_GLOBAL to FILE_MEMORY_BUFFER to reflect that the current > code is for buffer handling, this will allow the later (re-)addition > of FILE_MEMORY_GLOBAL for regular global memory. > > Signed-off-by: Hans de Goede <hdegoede at redhat.com> > --- > src/gallium/drivers/nouveau/codegen/nv50_ir.h | 2 +- > src/gallium/drivers/nouveau/codegen/nv50_ir_emit_gk110.cpp | 10 > +++++----- > src/gallium/drivers/nouveau/codegen/nv50_ir_emit_gm107.cpp | 6 +++--- > src/gallium/drivers/nouveau/codegen/nv50_ir_emit_nv50.cpp | 10 > +++++----- > src/gallium/drivers/nouveau/codegen/nv50_ir_emit_nvc0.cpp | 12 > ++++++------ > src/gallium/drivers/nouveau/codegen/nv50_ir_from_tgsi.cpp | 8 ++++---- > .../drivers/nouveau/codegen/nv50_ir_lowering_nvc0.cpp | 10 > +++++----- > src/gallium/drivers/nouveau/codegen/nv50_ir_peephole.cpp | 8 ++++---- > src/gallium/drivers/nouveau/codegen/nv50_ir_print.cpp | 2 +- > src/gallium/drivers/nouveau/codegen/nv50_ir_target_nv50.cpp | 6 +++--- > src/gallium/drivers/nouveau/codegen/nv50_ir_target_nvc0.cpp | 2 +- > 11 files changed, 38 insertions(+), 38 deletions(-) > > diff --git a/src/gallium/drivers/nouveau/codegen/nv50_ir.h > b/src/gallium/drivers/nouveau/codegen/nv50_ir.h > index 7b0eb2f..fdc2195 100644 > --- a/src/gallium/drivers/nouveau/codegen/nv50_ir.h > +++ b/src/gallium/drivers/nouveau/codegen/nv50_ir.h > @@ -332,7 +332,7 @@ enum DataFile > FILE_MEMORY_CONST, > FILE_SHADER_INPUT, > FILE_SHADER_OUTPUT, > - FILE_MEMORY_GLOBAL, > + FILE_MEMORY_BUFFER, > FILE_MEMORY_SHARED, > FILE_MEMORY_LOCAL, > FILE_SYSTEM_VALUE, > diff --git a/src/gallium/drivers/nouveau/codegen/nv50_ir_emit_gk110.cpp > b/src/gallium/drivers/nouveau/codegen/nv50_ir_emit_gk110.cpp > index 70f3c3f..02a1101 100644 > --- a/src/gallium/drivers/nouveau/codegen/nv50_ir_emit_gk110.cpp > +++ b/src/gallium/drivers/nouveau/codegen/nv50_ir_emit_gk110.cpp > @@ -1641,7 +1641,7 @@ CodeEmitterGK110::emitSTORE(const Instruction *i) > int32_t offset = SDATA(i->src(0)).offset;

[Nouveau] [Mesa-dev] [PATCH mesa 1/6] tgsi_build: Fix return of uninitialized memory in tgsi_*_instruction_memory
