The branch stable/14 has been updated by delphij: URL: https://cgit.FreeBSD.org/src/commit/?id=8241dbc3a2af6e422774904dfa42feb0241b36c5 commit 8241dbc3a2af6e422774904dfa42feb0241b36c5 Author: William Carrel <william.a@carrel.org> AuthorDate: 2026-01-08 08:56:27 +0000 Commit: Xin LI <delphij@FreeBSD.org> CommitDate: 2026-01-18 02:58:28 +0000 GCE: ARM64 Support: Add hw.pci.honor_msi_blacklist=0. This is required for MSI support on GCE ARM64 instances which is prerequisite to gve(4) not panicking at boot, and nvme(4) also has a real sad time without interrupts. Tested on a variety of c4a VMs. This is meant to be a temporary hack; long term fix would be to check for the hypervisor and quirk gve(4) device with PCI_QUIRK_ENABLE_MSI_VM.
