From 7a882f4f4e8bccd37598ac0449f91f4b3e0ee162 Mon Sep 17 00:00:00 2001 From: Arthur Hanson Rasmusson Date: Wed, 30 Sep 2026 23:10:52 -0400 Subject: gsp-phys: claim the physical GPU and stage real GSP firmware (backend rungs 1-2) 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. --- kernel/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'kernel/Makefile') diff --git a/kernel/Makefile b/kernel/Makefile index 8562430..6080164 100644 --- a/kernel/Makefile +++ b/kernel/Makefile @@ -16,6 +16,7 @@ open-iov-vfio-y := \ ioctl.o \ firmware_analyzer.o \ dynamic_rpc_dispatcher.o \ + gsp_phys_gpu.o \ architecture/architecture.o \ version/version.o -- cgit v1.2.3
