[Bug 102382] New: nv50ir: isImmediate doesn't properly work for integers if Value is typed as float
...nt: Driver/nouveau Assignee: nouveau at lists.freedesktop.org Reporter: karolherbst at gmail.com QA Contact: xorg-team at lists.x.org Created attachment 133728 --> https://bugs.freedesktop.org/attachment.cgi?id=133728&action=edit TGSI codegen should generate a texfetch instruction with a lod according to IMM[1].xxxx, which is of value 2, but in https://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/drivers/nouveau/codegen/nv50_ir_lowering_nvc0.cpp#n140 the isInteger(0) call assumes the Value being a F32, which leads to a is 2.8E-45 == 0 check returning true resu...

texelFetch sampler1/2DArray on nv50 gallium
...er2DArray. I nuked the logic in nv50_ir_lowering_nv50.cpp:604 that does the f32 -> u32 conversion, and it seems to be passing now. TBH, I have no clue how the parameters are passed around and what that a[] is, but it seems like it's a u32 to begin with? (Or that it's the same format that texfetch expects.) Perhaps this differs across card revisions? It would be interesting if someone with an original nv50, nva0, and nva3+ cards (those are the interesting 3d-related chip revisions) could run texelFetch as well to see whether it fails for them as well. Here's what I'm running: pigli...

[PATCH] nvc0/ir: move sample id to second source arg to fix sampler2DMS
The nvc0 texfetch instruction expects the sample id to be in the second source (usually used for the offset) rather than as part of the texture coordinate. This fixes all the sampler2DMS/Array tests on nvc0. Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> Cc: "10.1" <mesa-stable at lists.fr...

[PATCH 00/19] nv50: add sampler2DMS/GP support to get OpenGL 3.2
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
