https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=288848 Corvin Köhne <corvink@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |corvink@FreeBSD.org --- Comment #2 from Corvin Köhne <corvink@FreeBSD.org> --- I've started investigating which bits of my patches are required for NVIDIA GPUs. I've noticed that it's sufficient (for Linux guests, Windows untested) to set a valid INTPIN value in the PCI config space. Unfortunately, I'm unfamiliar with PCI legacy interrupts and bhyve doesn't support them for passthrough devices. So, I don't know which side effects can occur due to this change. I've created a review: https://reviews.freebsd.org/D51892 -- You are receiving this mail because: You are the assignee for the bug.
