intel_gpu_dump [ filename ]
DESCRIPTIONintel_gpu_dump is a tool to log the current state of an Intel GPU when it is hung, for later analysis. It requires kernel 2.6.30rc1 or newer, debugfs mounted on /sys/kernel/debug or /debug, and root privilege for mapping the device to inspect it.
Decodes just one batchbuffer or ringbuffer dump, rather than dumping all
of the GPU state.
