*	gsp-phys: read-only falcon state probe for the boot rung	Arthur Hanson Rasmusson	14 days
\| \| \| \| \| \| \|	Logs both falcons' run/halt bits, the RISC-V active bit, WPR2 up/down and the security-falcon mailboxes when the physical GPU is claimed. Verified live: GSP and SEC2 halted, RISC-V inactive, WPR2 down (HI=0). This is the read-only half of the real boot rung; no device state is written.
*	gsp-phys: claim the physical GPU and stage real GSP firmware (backend rungs 1-2)	Arthur Hanson Rasmusson	14 days
	Rung 1 (ownership): a default-off gsp_phys_gpu module param; on claim the distribution driver is released from 10de:1ed3, our pci_driver binds it, BAR0/1/3 are mapped and the falcon state is sampled; release unbinds ours and rebinds the distribution driver. Verified live: claim reads BOOT0=0x164000a1 with the falcon halted and mailboxes clear; rmmod rebinds nvidia and nvidia-smi stays healthy. Rung 2 (firmware): while the device is owned, gsp_phys_fw (default nvidia/570.211.01/gsp_tu10x.bin) is fetched with request_firmware, checked as ELF64 RISC-V, and its sections are logged (.fwimage, .fwversion, .fwsignature_tu10x). The image is held for the boot rung. The claim is default-off; the emulation path is unchanged.
