Subject: [Linux-ia64] PCI_BUSES_TO_SCAN off by 1?
Date: Fri, 30 Aug 2002 20:45:42 +0000 [thread overview]
Message-ID: <marc-linux-ia64-105590701906005@msgid-missing> (raw)
Hi all,
Is there any reason we don't scan the last PCI bus on IA64?
arch/ia64/kernel/pci.c has PCI_BUSES_TO_SCAN set to 255 instead
of 256, which prevents the kernel from scanning bus 255. This
causes is some problems since some of our machines (ie, the
Itanium2 "tiger") place chipset registers in PCI config space on
the last PCI bus. I've run with it set to 256 on the Lion and
some other machines with no apparent problems.
Thanks,
Kevin
