2006-01-09[PATCH] PCI: Export pci_cfg_space_sizeBenjamin Herrenschmidt
The powerpc PCI code sets up the PCI tree without doing config space accesses in most cases, from the firmware tree. However, it still wants to call pci_cfg_space_size() under some conditions, thus it needs to be made non-static (though I don't see a point to export it to modules).

2006-01-09[PATCH] PCI: use bus numbers sparsely, if necessaryDominik Brodowski
Add a warning if a child bus may be inaccessible because the parent bridge has wrong secondary or subordinate bus numbers. Note that this may or may not happen on "transparent" bridges, as can be seen in bug #5557. Also, if we do not fix up the assignment of bus numbers, try to make use of the bus number space available.

This patch disables power fault, MRL sensor and presence detection interrupts when a PCIe slot is powered-off and enables those interrupts when it is powered-on again.

2006-01-09[PATCH] PCI Quirk: 1K I/O space granularity on Intel P64H2Daniel Yeisley
I've implemented a quirk to take advantage of the 1KB I/O space granularity option on the Intel P64H2 PCI Bridge. I had to change probe.c because it sets the resource start and end to be aligned on 4k boundaries (after the quirk sets them to 1k boundaries). I've tested this patch on a Unisys ES7000-600 both with and without the 1KB option enabled. I also tested this on a 2 processor Dell box that doesn't have a P64H2 to make sure there were no negative affects there.

2006-01-09[PATCH] shpchp: fix improper wait for command completionKenji Kaneshige
Current SHPCHP driver uses msleep_interruptible() function to wait for a command completion event.

With this patch, command completion becomes faster as follows: o Without this patch # time echo 1 > power real 0m4.708s user 0m0.000s sys 0m0.524s o With this patch # time echo 1 > power real 0m2.221s user 0m0.000s sys 0m0.532s Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2005-12-13[PATCH] add boot option to control Intel SATA/PATA combined modeJesse Barnes
Combined mode sucks. Especially when both libata and the legacy IDE drivers try to drive ports on the same device, since that makes DMA rather difficult. This patch addresses the problem by allowing the user to control which driver binds to the ports in a combined mode configuration. In many cases, they'll probably want the libata driver to control both ports since it can use DMA for talking with ATAPI devices (when libata.atapi_enabled=1 of course). It also allows the user to get old school behavior by letting the legacy IDE driver bind to both ports. But neither is forced, the patch doesn't change current behavior unless one of combined_mode=ide or combined_mode=libata is passed on the boot line. Either of those options may require you to access your devices via different device nodes (/dev/hd* in the ide case and /dev/sd* in the libata case), though of course if you have udev installed nicely you may not notice anything. :) Let me know if the documentation is too cryptic, I'd be happy to expand on it if necessary. I think most users will want to boot with 'combined_mode=libata' and add 'options libata atapi_enabled=1' to their modules.conf to get good DVD playing and disk behavior (haven't tested CD or DVD writing though). I'd much rather things behave sanely by default (i.e. DMA for devices on both ports), but apparently that's difficult given the various chip bugs and hardware configs out there (not to mention that people's drives may suddenly change from /dev/hdc to /dev/sdb), so this boot option may be the correct long term fix.

2005-11-23[PATCH] PCI Express Hotplug: clear sticky power-fault bitRajesh Shah

2005-11-10[PATCH] PCI: Change MSI to use physical delivery mode alwaysAshok Raj
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.
