[PATCH] x86: pci_assign_unassigned_resources() update
I had some time to think about PCI assign issues in 2.6.13-rc series. The major problem here is that we call pci_assign_unassigned_resources() way too early - at subsys_initcall level. Therefore we give no chances to ACPI and PnP routines (called at fs_initcall level) to reserve their respective resources properly, as the comments in drivers/pnp/system.c and drivers/acpi/motherboard.c suggest: /** * Reserve motherboard resources after PCI claim BARs, * but before PCI assign resources for uninitialized PCI devices */ So I moved the pci_assign_unassigned_resources() call to pcibios_assign_resources() (fs_initcall), which should hopefully fix a lot of problems and make PCIBIOS_MIN_IO tweaks unnecessary. Other changes: - remove resource assignment code from pcibios_assign_resources(), since it duplicates pci_assign_unassigned_resources() functionality and actually does nothing in 2.6.13; - modify ROM assignment code as per Ben's suggestion: try to use firmware settings by default (if PCI_ASSIGN_ROMS is not set); - set CARDBUS_IO_SIZE back to 4K as it's a wonderful stress test for various setups. Confirmed by Tero Roponen <teanropo@cc.jyu.fi> (who had problems with the 4kB CardBus IO size previously). Signed-off-by: Linus Torvalds <torvalds@osdl.org>
