open-iov.git/tools/cuda-ab/transformer_async.cu, branch master Open-IOV vGPU-IO: host-side GSP emulation for unmodified NVIDIA guest drivers https://git.vgpu.io/open-iov.git/atom?h=master 2026-10-22T00:51:27+00:00 r436 full sysmem PTE aperture/VOL matrix: gsp_phys_rmcall_pte_coh becomes a 4-mode selector (0=0xf aperture3+VOL historical, 1=0xd aperture2+VOL r431, 2=0x5 aperture2 non-volatile, 3=0x7 aperture3 non-volatile) applied consistently to the leaf PTE and the single PDE (bit0 = IS_PDE there), so the r431 finding (aperture 2 with VOL still 1 is a pair the reference RM never emits) can be A/B'd against the consistent encodings 2026-10-22T00:51:27+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-10-22T00:51:27+00:00 urn:sha1:55a77193c7b3bf3bcebf7e75e79b0c615a3a2fb3
