Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2025-09-30T18:21:27+00:00 2025-09-30T18:21:27+00:00 James Helferty (NVIDIA) jhelferty@nvidia.com 2025-09-30T18:21:27+00:00 urn:sha1:8086adc90b69f3199767c0617e2c429ce6b27f67 Enables all tests/metal/ tests that can be easily enabled. These tests were not originally designed as render tests; they are generally being enabled for pipecleaning purposes, and will not be rigorously testing the corresponding funcitonality. Where they cannot be enabled as render tests, and a metallib test wasn't already enabled, a metallib test was enabled instead (where possible). Fixes #7892 2025-08-01T09:18:53+00:00 Harsh Aggarwal (NVIDIA) haaggarwal@nvidia.com 2025-08-01T09:18:53+00:00 urn:sha1:bdda8a90cdd44ca822b21233ac988f92d1f20826 * Fix 7441: CUDA boolean vector layout to use 1-byte elements Boolean vectors (bool1, bool2, bool3, bool4) were incorrectly implemented as integer-based types using 4 bytes per element instead of actual 1-byte boolean elements on CUDA targets. Changes: - Update CUDA prelude to define boolean vectors as structs with bool fields instead of typedef aliases to integer vectors - Implement CUDALayoutRulesImpl::GetVectorLayout to use 1-byte alignment for boolean vectors, matching actual CUDA memory layout behavior - Update make_bool functions to populate struct fields correctly This ensures boolean vectors have the same memory layout as bool[4] arrays: - bool1: 1 byte (was 4 bytes) - bool2: 2 bytes (was 8 bytes) - bool3: 3 bytes (was 12 bytes) - bool4: 4 bytes (was 16 bytes) Fixes memory layout mismatch between Slang reflection API and actual CUDA compilation, achieving 75% memory savings for boolean vector usage. * Fix CI issues - Add and update associated functions and operators * Make boolX same as uchar * Use align construct on struct for boolX * Improve Test case for robust alignment checks * Formatting * Disable selected slangpy tests * add metal check which is slightly different than cuda * Test-1 * Test-2 * Test-3 * Test-4 * ReflectionChange * cleanup and update * _slang_select with plain bool is needed for reverse-loop-checkpoint-test 2025-06-10T17:35:01+00:00 kaizhangNV 149626564+kaizhangNV@users.noreply.github.com 2025-06-10T17:35:01+00:00 urn:sha1:d93c71d53f969e5cd3911fbada0e566cd1887ec1 Apply argument buffer tier2 rule when using parameter block for Metal target.
