about

nx_amd_pm4_gate.nx -- gate for the sovereign AMD PM4 command-submission encoder (nx_pm4_asm) = the AMD R1 rung. Verifies the PM4 Type-3 packet headers our encoder produces against the documented AMD format for the real IT opcodes tinygrad's AM driver submits (DISPATCH/SET_SH_REG/ACQUIRE_MEM/RELEASE_MEM/WAIT_REG_MEM). HONEST SCOPE: spec-faithful (documented PM4 Type-3 + tinygrad-cross-referenced), NOT yet toolchain-bit-exact (needs llvm-mc -triple=amdgcn / ROCm). No hw writes (Rule 26). expect_exit: 0 license_tier: ORIGINAL
