At present, simply rolling back: sys/external/bsd/drm2/linux/linux_pci.c to the revision where MSI is enabled (r1.8 in -current) allows intel- and radeon-equipped machines to use MSI, while nouveau has it explicitly disabled in the HEAD revision of: sys/external/bsd/drm2/dist/drm/nouveau/nvkm/subdev/pci/nouveau_nvkm_subdev_pci_base.c so nouveau machines use INTx. I've checked this with plain GENERIC and one with the above file rolled back. With plain generic, nouveau, intel, and radeon all work and have MSI off. With the modified GENERIC, nouveau systems work (MSI off) and intel and radeon systems work (MSI on). -- |/"\ John D.
