On GFX rings align_mask is 0xff, so the loop wrote 256 dwords into a 64-byte buffer, causing a kernel page fault. The IB only needs to be a minimal NOP shell to schedule the job; the cleaner shader itself is emitted on the ring via emit_cleaner_shader(). Fill 16 dwords to match the allocation. v2: Use ib_size_dw variable (Lijo) (cherry picked from commit bf21af331ebf72d0935fd70c73192414a422c03a) Join the discussion | GCVE Database | 08/11/2026, 00:00:00 UTC Added: 08/12/2026, 20:14:20 UTC |
