| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify PCI Bridge Control ISA flag for clarity This patch changes PCI_BRIDGE_CTL_NO_ISA to PCI_BRIDGE_CTL_ISA and modifies it's clarifying comment and locations where used. The change reduces the chance of future confusion since it makes the set/unset meaning of the bit the same in both the bridge control register and bridge_ctl field of the pci_bus struct.

| * PCI: avoid P2P prefetch window for expansion ROMsGary Hade2007-10-121-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid creating P2P prefetch window for expansion ROMs Because of the future possibility that P2P prefetch windows will contain address ranges above 4GB some BIOSes are providing space in the P2P non-prefetch windows for expansion ROMs. This is due to expansion ROM BAR 32-bit limitation. When expansion ROM BARs without BIOS assigned address(es) are currently found behind a P2P bridge, the kernel attempts to create a P2P prefetch window for them even though space for them has already been provided in the non-prefetch window. _CRS on some systems with certain resource conservation conscious BIOSes may not provide the extra 1MB or more memory resource needed for the expansion ROM motivated prefetch window causing resource allocation errors. This change corrects the problem by removing IORESOURCE_PREFETCH from the expansion ROM flags initialization. It also removes IORESOURCE_CACHEABLE which seems inappropriate if only non-cacheable memory is available.

| * PCI: skip ISA ioresource alignment on some systemsGary Hade2007-10-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Skip ISA ioresource alignment on some systems To conserve limited PCI i/o resource on some IBM multi-node systems, the BIOS allocates (via _CRS) and expects the kernel to use addresses in ranges currently excluded by pcibios_align_resource() [i386/pci/i386.c]. This change allows the kernel to use the currently excluded address ranges on the IBM x3800, x3850, and x3950.

| * PCI: remove transparent bridge sizingGary Hade2007-10-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove transparent bridge sizing. Due to code in pci_read_bridge_bases() [drivers/pci/probe.c] the child bus of a transparent bridge already has access to the parent bus resources so transparent bridge sizing appears unnecessary. The bridge sizing includes alignment and granularity adjustments that can cause significantly more memory to be reserved from the parant bus than required by devices on the child bus and allotted by _CRS.

| | | | | | | | | | | | | | | | | | | | | | When a /proc/bus/pci file is written to, the size of that PCI device's configuration space must be written to the inode.

* | PCI: Run k8t_sound_hostbridge quirk only when neededJean Delvare2007-08-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The k8t_sound_hostbridge PCI quick fires on my motherboard (Jetway K8M8MS) while it shouldn't: the on-board sound chip is not disabled and is working just fine. Looking at the code, I see that we are running the quirk for two distinct register values (0x88 and 0xc8) and then clear bit 6 (0x40). However value 0x88 already has bit 6 cleared so this is a no-op. This is what happens on my board. Thus I believe that the quirk should only be run for register value 0xc8.

Ok, lets kill the message. As Alois Nešpor also saw, that's fixed up by Yenta, so PCI does not have to warn about it. PCI could still warn about it if is_cardbus is 0 in that instance of pci_scan_bridge(), but so far I have not seen a report where this would have been the case so I think we can spare the kernel of that check (removes ~300 lines of asm) unless debugging is done. History: The whole check was added in the days before we had the fixup for this in Yenta and pci=assign-busses was the only way to get CardBus cards detected on many (not all) of the machines which give this warning. In theory, there could be cases when this warning would be triggered and it's not cardbus, then the warning should still apply, but I think this should only be the case when working on a completely broken PCI setup, but one may have already enabled the debug code in drivers/pci and the patched check would then trigger. I do not sign this off yet because it's completely untested so far, but everyone is free to test it (with the #ifdef DEBUG replaced by #if 1 and pr_debug( changed to printk(. We may also dump the whole check (remove everything within the #ifdef from the source) if that's perferred. On Alois Nešpor's machine this would then (only when debugging) this message: "PCI: Bus #0b (-#0e) is partially hidden behind transparent bridge #0a (-#0b)" "partially" should be in the message on his machine because #0b of #0b-#0e is reachable behind #0a-#0b, but not #0c-#0e. But that differentiation is now moot anyway because the fixup in Yenta takes care of it as far as I could see so far, which means that unless somebody is debugging a totally broken PCI setup, this message is not needed anymore, not even for debugging PCI. Ok, here the patch with the following changes: * Refined to say that the bus is only partially hidden when the parent bus numbers are not totally way off (outside of) the child bus range * remove the reference to pci=assign-busses and the plea to report it We could add a pure source code-only comment to keep a reference to pci=assign-busses the in case when this is triggered by someone who is debugging the cause of this message and looking the way to solve it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | quirk_e100_interrupts() is called after PCI controller is initialized and before PCI bus enumeration is performed. On some powerpc platforms which modify PCI controller configuration and set different MEM and IO windows than those set by firmware quirk_e100_interrupt() is causing kernel panic as it tries to read from device BAR0 offets which at this time points to a invalid PCI window (set by firmware). This patch delays the quirk_100_interrupt() to pci_fixup_final phase, which happens after bus enumeration and before PCI enable and device driver initialization.
