Class Members
uint32_t base_count Number of DWORDs of batchbuffer data.
uint32_t * base_data CPU Virtual address of the start of the batchbuffer data.
uint32_t base_hw_offset GPU address of the start of the batchbuffer data.
uint32_t count DWORDs of remaining batchbuffer data starting from the packet.
uint32_t * data CPU virtual address of the start of the current packet.
uint32_t devid PCI device ID.
bool dump_past_end Whether to dump the dwords after MI_BATCHBUFFER_END. This sometimes provides clues in corrupted batchbuffers, and is used by the intel-gpu-tools.
int gen Shorthand device identifier: 3 is 915, 4 is 965, 5 is Ironlake, etc.
uint32_t head GPU head and tail pointers, which will be noted in the dump, or ~0.
uint32_t hw_offset GPU address of the start of the current packet.
FILE * out stdio file where the output should land. Defaults to stdout.
bool overflowed
uint32_t tail
