550  *                   available for all ASICs.
551  * @AMD_RESET_MODE2: Resets a lesser level of IPs compared to MODE1. Which IPs
552  *                   are reset depends on the ASIC. Notably doesn't reset IPs
553  *                   shared with the CPU on APUs or the memory controllers (so

556  * @AMD_RESET_BACO: BACO (Bus Alive, Chip Off) method powers off and on the card
557  *                  but without powering off the PCI bus. Suitable only for
558  *                  discrete GPUs.
559  * @AMD_RESET_PCI: Does a full bus reset using core Linux subsystem PCI reset
560  *                 and does a secondary bus reset or FLR, depending on what the
