Sometimes when user is trying to get error state out from debugfs after gpu hang, the memory is low and/or fragmented enough that kmalloc in seq_file will fail. Prevent big kmalloc by avoiding seq_file and instead convert error state to string in smaller chunks. v2: better alloc flags, better truncate, correct locking, and error handling improvements (Chris Wilson) v3: printf annotations (Daniel Vetter) Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |
