https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=292750 Bug ID: 292750 Summary: Jailed bhyve passthru fails with: "bhyve: PCI device at 9/0/0 is not using the ppt(4) driver" Product: Base System Version: 15.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bhyve Assignee: virtualization@FreeBSD.org Reporter: leper4@protonmail.com I run a jailed bhyve with some PCI passthru devices, this setup worked fine for quite a while on 14-STABLE. After the upgrade to 15-STABLE passing through one of the devices failed with: bhyve: PCI device at 9/0/0 is not using the ppt(4) driver Device emulation initialization error: Operation not permitted Even though the ppt driver is attached to that device. Using non-jailed bhyve makes this work. During some of the bisecting/testing it seemed like excluding just that device from passthru made the other devices work, however that specific device makes the others somewhat pointless[2]. I sort of bisected[1] vmm/bhyve changes since 14-STABLE and is the culprit https://cgit.freebsd.org/src/commit/?id=e2d6c959b29d85a83a0c827b02f3303b115daf03 as reverting it fixes this in the jailed case. priv_check(td, PRIV_DRIVER); most likely fails in a jail, and there is no jail.conf allow.driver or similar property that could make that work. [1] Using git revert with all commits touching bhyve/vmm and related files. Mainly due to limiting downtime of the machine in question. [2] The device is an AMD APU (integrated graphics) with a VBIOS ROM. -- You are receiving this mail because: You are the assignee for the bug.home | help
