From d6eb44c8b0542c4756eb190fcdcfa0351c5812a3 Mon Sep 17 00:00:00 2001 From: Marcel Moolenaar Date: Fri, 23 Oct 2009 22:53:01 +0000 Subject: [PATCH] BIOSes, buggy or otherwise, are i386 or amd64 specific. Have the early USB takeover enabled for i386 and amd64 by default. This also avoids a panic on PowerPC where the resource isn't released properly and we find a busy resource when the USB host controller wants to allocate it... --- sys/dev/pci/pci.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/sys/dev/pci/pci.c b/sys/dev/pci/pci.c index e60ee234c859..8922aba40180 100644 --- a/sys/dev/pci/pci.c +++ b/sys/dev/pci/pci.c @@ -274,7 +274,11 @@ TUNABLE_INT("hw.pci.honor_msi_blacklist", &pci_honor_msi_blacklist); SYSCTL_INT(_hw_pci, OID_AUTO, honor_msi_blacklist, CTLFLAG_RD, &pci_honor_msi_blacklist, 1, "Honor chipset blacklist for MSI"); +#if defined(__i386__) || defined(__amd64__) static int pci_usb_takeover = 1; +#else +static int pci_usb_takeover = 0; +#endif TUNABLE_INT("hw.pci.usb_early_takeover", &pci_usb_takeover); SYSCTL_INT(_hw_pci, OID_AUTO, usb_early_takeover, CTLFLAG_RD | CTLFLAG_TUN, &pci_usb_takeover, 1, "Enable early takeover of USB controllers.\n\
