It used to work with the old RES[] code and if one cannot specify a source swizzle, then how can I do something like LOAD TEMP[0].y, MEMORY[0], address And get the data at absolute global memory address "address" into TEMP[0].y ? This is a must-have for llvm to be able to generate working TGSI code, I do not see any

That's wrong. The spec for the instruction needs to be clarified... The current nouveau impl is correct - only the .x of the address should be loaded, with up to 16 bytes read into the destination.

[+radeon folk] Marek, Nicolai, Bas - please have a look at the doc change and let us know if you think this will cause a problem for radeon. Hans is solving the issue that he wants to swizzle the data loaded from the image/buffer/whatever before sticking it into the dst register. -ilia On Thu, Apr 21, 2016 at 8:39 AM, Hans de Goede <hdegoede at redhat.com> wrote: > The llvm TGSI

The llvm TGSI backend uses pointers in registers and does things like: LOAD TEMP[0].y, MEMORY[0], TEMP[0] Expecting the data at address TEMP[0].x to get loaded to TEMP[0].y. But this will cause the data at TEMP[0].x + 4 to be loaded instead. This commit adds support for a swizzle suffix for the 1st source operand, which allows using: LOAD TEMP[0].y, MEMORY[0].xxxx, TEMP[0] And actually

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.

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. Disable all the dead code.

This little "hack" fixes the use of OpenCL global memory buffers with nouveau, but clearly the #if 0 is not a solution as it breaks buffers with GLSL. The reason I'm posting this as an RFC patch is to discuss how to solve this properly, 2 solutions come to mind: 1) Use separate nv50_ir::FILE_MEMORY_xxx values for buffers versus TGSI_FILE_MEMORY with TGSI_MEMORY_TYPE_GLOBAL,

Hi, Here are patches which implement the support for OpenCL kernel input parameters we discussed. They also add the tgsi parsing bits for adding support for global / local mem, but no implementation yet. Regards, Hans

I went through the gallium-nine tree and picked out nouveau patches that are general bug-fixes. The first bunch I'd like to also get into 10.2. I've reviewed all of them and they make sense to me, but sending them out for public review as well in case there are any objections. Unless I hear objections, I'd like to push this by Friday.

Some of the lowering steps we currently do for FILE_MEMORY_GLOBAL only apply to buffers, making it impossible to use FILE_MEMORY_GLOBAL for OpenCL global buffers. This commits changes the buffer code to use FILE_MEMORY_BUFFER at the ir_from_tgsi and lowering steps, freeing use of FILE_MEMORY_GLOBAL for use with OpenCL global buffers. Note that after lowering buffer accesses use the

OK, so there's a bunch of stuff in here. The geometry stuff is based on the work started by Bryan Cain and Christoph Bumiller. Patches 01-12: Add support for geometry shaders and fix related issues Patches 13-14: Make it possible for fb clears to operate on texture attachments with an explicit layer set (as is allowed in gl 3.2). Patches 15-17: Make ARB_texture_multisample work

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
