I forgout about this earlier, sorry. We probably should also explicitly release any resources cached in sc->vga_bios and sc->vga_bars. In theory they should be clear by the time bus_generic_detach finishes, but perhaps we should walk the resources and whine if they aren't released and then release them. -- John Baldwin _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
