* [PATCH] PCI: Change MSI to use physical delivery mode alwaysAshok Raj2005-11-101-8/+12
| | | | | | | | | | | | | | | | | MSI hardcoded delivery mode to use logical delivery mode. Recently x86_64 moved to use physical mode addressing to support physflat mode. With this mode enabled noticed that my eth with MSI werent working. msi_address_init() was hardcoded to use logical mode for i386 and x86_64. So when we switch to use physical mode, things stopped working. Since anyway we dont use lowest priority delivery with MSI, its always directed to just a single CPU. Its safe and simpler to use physical mode always, even when we use logical delivery mode for IPI's or other ioapic RTE's.

* [PATCH] PCI/libata INTx cleanupBrett M Russ2005-09-081-8/+2
| | | | | | | | | Simple cleanup to eliminate X copies of the pci_enable_intx() function in libata. Moved ahci.c's pci_intx() to pci.c and use it throughout libata and msi.c. Signed-off-by: Brett Russ <russb@emc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] x86/x86_64: deferred handling of writes to /proc/irqxx/smp_affinityAshok Raj2005-09-071-12/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When handling writes to /proc/irq, current code is re-programming rte entries directly. This is not recommended and could potentially cause chipset's to lockup, or cause missing interrupts. CONFIG_IRQ_BALANCE does this correctly, where it re-programs only when the interrupt is pending. The same needs to be done for /proc/irq handling as well. Otherwise user space irq balancers are really not doing the right thing. - Changed pending_irq_balance_cpumask to pending_irq_migrate_cpumask for lack of a generic name. - added move_irq out of IRQ_BALANCE, and added this same to X86_64 - Added new proc handler for write, so we can do deferred write at irq handling time. - Display of /proc/irq/XX/smp_affinity used to display CPU_MASKALL, instead it now shows only active cpu masks, or exactly what was set. - Provided a common move_irq implementation, instead of duplicating when using generic irq framework. Tested on i386/x86_64 and ia64 with CONFIG_PCI_MSI turned on and off. Tested UP builds as well. MSI testing: tbd: I have cards, need to look for a x-over cable, although I did test an earlier version of this patch. Will test in a couple days.

* [PATCH] PCI: 6700/6702PXH quirkKristen Accardi2005-08-161-1/+4
| | | | | | | | | | | | | On the 6700/6702 PXH part, a MSI may get corrupted if an ACPI hotplug driver and SHPC driver in MSI mode are used together. This patch will prevent MSI from being enabled for the SHPC as part of an early pci quirk, as well as on any pci device which sets the no_msi bit.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
