Raw Normal View History

Linux-2.6.12-rc2 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!

This allows device drivers to enable MSI (Message Signaled
Interrupts). Message Signaled Interrupts enable a device to
generate an interrupt using an inbound Memory Write on its
PCI bus instead of asserting a device IRQ pin.
[PATCH] PCI: Provide a boot parameter to disable MSI Several drivers are starting to grow options to disable MSI. However, it's often a host chipset issue, not something which individual drivers should handle. So we add the pci=nomsi kernel parameter to allow the user to disable MSI modes for systems we haven't added to the quirk list yet.

Use of PCI MSI interrupts can be disabled at kernel boot time
by using the 'pci=nomsi' option. This disables MSI for the
entire system.

help
Say Y here if you want to include support for the deprecated
pci_find_slot() and pci_find_device() APIs. Most drivers have
been converted over to using the proper hotplug APIs, so this
option serves to include/exclude only a few drivers that are
still using this API.

Say Y here if you want the PCI core to produce a bunch of debug

problem with PCI support and want to see more of what is going on.
When in doubt, say N.
[PATCH] Initial generic hypertransport interrupt support This patch implements two functions ht_create_irq and ht_destroy_irq for use by drivers. Several other functions are implemented as helpers for arch specific irq_chip handlers. The driver for the card I tested this on isn't yet ready to be merged. However this code is and hypertransport irqs are in use in a few other places in the kernel. Not that any of this will get merged before 2.6.19 Because the ipath-ht400 is slightly out of spec this code will need to be generalized to work there. I think all of the powerpc uses are for a plain interrupt controller in a chipset so support for native hypertransport devices is a little less interesting. However I think this is a half way decent model on how to separate arch specific and generic helper code, and I think this is a functional model of how to get the architecture dependencies out of the msi code.

This allows native hypertransport devices to use interrupts.
If unsure say Y.
