* Fix bogus PCI quirk for e100Benjamin Herrenschmidt2007-09-281-4/+3
| | | | | | | | | | | | | | | | Linas reported me that some machines were crashing at boot in quirk_e100_interrupt. It appears that this quirk is doing an ioremap directly on a PCI BAR value, which isn't legal and will cause all sorts of bad things to happen on architectures where PCI BARs don't directly match processor bus addresses. This fixes it by using the proper PCI resources instead which is possible since the quirk has been moved by a previous commit to happen late enough for that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous events patch added a netlink event for every user of the legacy /proc/acpi/event interface. However, some users of /proc/acpi/event are really input events, and they already report their events via the input layer. Introduce a new interface, acpi_bus_generate_netlink_event(), which is explicitly called by devices that want to repoprt events via netlink. This allows the input-like events to opt-out of generating netlink events.

* | 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.

| * [POWERPC] Rewrite IO allocation & mapping on powerpc64Benjamin Herrenschmidt2007-06-141-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This rewrites pretty much from scratch the handling of MMIO and PIO space allocations on powerpc64. The main goals are: - Get rid of imalloc and use more common code where possible - Simplify the current mess so that PIO space is allocated and mapped in a single place for PCI bridges - Handle allocation constraints of PIO for all bridges including hot plugged ones within the 2GB space reserved for IO ports, so that devices on hotplugged busses will now work with drivers that assume IO ports fit in an int. - Cleanup and separate tracking of the ISA space in the reserved low 64K of IO space. No ISA -> Nothing mapped there. I booted a cell blade with IDE on PIO and MMIO and a dual G5 so far, that's it :-) With this patch, all allocations are done using the code in mm/vmalloc.c, though we use the low level __get_vm_area with explicit start/stop constraints in order to manage separate areas for vmalloc/vmap, ioremap, and PCI IOs. This greatly simplifies a lot of things, as you can see in the diffstat of that patch :-) A new pair of functions pcibios_map/unmap_io_space() now replace all of the previous code that used to manipulate PCI IOs space. The allocation is done at mapping time, which is now called from scan_phb's, just before the devices are probed (instead of after, which is by itself a bug fix). The only other caller is the PCI hotplug code for hot adding PCI-PCI bridges (slots). imalloc is gone, as is the "sub-allocation" thing, but I do beleive that hotplug should still work in the sense that the space allocation is always done by the PHB, but if you unmap a child bus of this PHB (which seems to be possible), then the code should properly tear down all the HPTE mappings for that area of the PHB allocated IO space. I now always reserve the first 64K of IO space for the bridge with the ISA bus on it. I have moved the code for tracking ISA in a separate file which should also make it smarter if we ever are capable of hot unplugging or re-plugging an ISA bridge. This should have a side effect on platforms like powermac where VGA IOs will no longer work. This is done on purpose though as they would have worked semi-randomly before. The idea at this point is to isolate drivers that might need to access those and fix them by providing a proper function to obtain an offset to the legacy IOs of a given bus.

| * | PCI: Only build PCI syscalls on architectures that want themMatthew Wilcox2007-07-111-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PCI syscalls are built on every architecture except X86, but only a few have ever hooked them up. Use a new Kconfig symbol to save a couple of kB on the architectures that have never used the syscalls. Tested on x86 and ia64 only.

| * | PCI: hotplug: acpiphp: avoid acpiphp "cannot get bridge info" PCI hotplug ↵Gary Hade2007-07-111-2/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | failure On some systems, the ACPI bus check event can reference a bridge that is higher in the ACPI hierarchy than the bridge immediately above the hotplug PCI slot into which an adapter was just inserted. The current 'acpiphp' code expects the bus check event to reference the bridge immediately above the slot that received the adapter so the hotplug operation can fail on these systems with the message "acpiphp_glue: cannot get bridge info". This change fixes the problem by re-enumerating all slots that lie below the bridge referenced by the bus check event, including those slots that may be located under lower level PCI-to-PCI bridge(s).

| * | PCI: hotplug: acpiphp: fix slot poweroff problem on systems without _PS3Gary Hade2007-07-113-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On systems where the optional _PS3 ACPI object is not implemented acpiphp fails to power off the slot. This is happening because the current code does not attempt to remove power using the _EJ0 ACPI object. This patch restores the _EJ0 evaluation attempt which was apparently inadvertently removed from the power-off sequence when the _EJ0 evaluation code was relocated from power_off_slot() to acpiphp_eject_slot().

| * | PCI: Change all drivers to use pci_device->revisionAuke Kok2007-07-112-17/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance. Compile tested with make all{yes,mod}config on x86_64 and i386.
