On recent emulator GTT entry setup for aub dump needs mem type as GTT_ENTRY instead of NONLOCAL. NONLOCAL would write data in main memory space which is wrong with new memory layout. GTT_ENTRY write would setup GTT memory pool and other required internal buffers. With this I can run aub dump on latest release without crash.

No regression found on older HW with previous emulator with memory type change. And verify this on more recent emulators that without crash and produce result fine. diff --git a/intel/intel_bufmgr_gem.c b/intel/intel_bufmgr_gem.c index 14e92c9..cf85bb8 100644 --- a/intel/intel_bufmgr_gem.c +++ b/intel/intel_bufmgr_gem.c @@ -3180,7 +3180,8 @@ drm_intel_bufmgr_gem_set_aub_dump(drm_intel_bufmgr *bufmgr, int enable) /* Set up the GTT.
