The changes as part of the Contexts state now include: **** Contexts **** [HWCTX].replay_offset: 0x0 [HWCTX].replay_length: 0xd000 and the changes as part of the VM state now include: **** VM state **** VM.uapi_flags: 0x1 [40000].length: 0x2000 [40000].properties: read_write|bo|mem_region=0x1|pat_index=2|cpu_caching=1 [40000].data: &-)\3!!E9mzzzzzzzzzz In order to be able to replay a GPU hang from a devcore dump file new properties have been added describing the offset and the length of the affected hw context as well as a global VM flag and several VMA property types: memory region, bo caching, pat index, memory permission and memory type.
