2008-10-20PCI PM: Introduce function pci_wake_from_d3Rafael J. Wysocki
Many device drivers use the following sequence of statements to enable the device to wake up the system while being in the D3_hot or D3_cold low power state: pci_enable_wake(pdev, PCI_D3hot, 1); pci_enable_wake(pdev, PCI_D3cold, 1); However, the second call is not necessary if the first one succeeds (the ordering of the statements above doesn't matter here) and it may even be harmful, because we are not supposed to enable PME# after the wake-up power has been enabled for the device. To allow drivers to overcome this problem, introduce function pci_wake_from_d3() that will enable the device to wake up the system from any of D3_hot and D3_cold as long as the wake-up from at least one of them is supported.

2008-10-20PCI: allow quirks to be compiled outThomas Petazzoni
This patch adds the CONFIG_PCI_QUIRKS option which allows to remove all the PCI quirks, which are not necessarily used on embedded systems when PCI is working properly. As this is a size-reduction option, it depends on CONFIG_EMBEDDED. It allows to save almost 12 kilobytes of kernel code: text data bss dec hex filename 1287806 123596 212992 1624394 18c94a vmlinux.old 1275854 123596 212992 1612442 189a9a vmlinux -11952 0 0 -11952 -2EB0 +/- This patch has originally been written by Zwane Mwaikambo <zwane@arm.linux.org.uk> and is part of the Linux Tiny project.

2008-10-20PCI: Check dynids driver_data value for validityJean Delvare

2008-10-20PCI: remove dynids.use_driver_dataMilton Miller
The driver flag dynids.use_driver_data is almost consistently not set, and causes more problems than it solves. It was initially intended as a flag to indicate whether a driver's usage of driver_data had been carefully inspected and was ready for values from userspace. That audit was never done, so most drivers just get a 0 for driver_data when new IDs are added from userspace via sysfs. So remove the flag, allowing drivers to see the data directly (a followon patch validates the passed driver_data value against what the drivers expect).

2008-10-02Check mapped ranges on sysfs resource filesLinus Torvalds
This is loosely based on a patch by Jesse Barnes to check the user-space PCI mappings though the sysfs interfaces. Quoting Jesse's original explanation: It's fairly common for applications to map PCI resources through sysfs. However, with the current implementation, it's possible for an application to map far more than the range corresponding to the resourceN file it opened. This patch plugs that hole by checking the range at mmap time, similar to what is done on platforms like sparc64 in their lower level PCI remapping routines. It was initially put together to help debug the e1000e NVRAM corruption problem, since we initially thought an X driver might be walking past the end of one of its mappings and clobbering the NVRAM. It now looks like that's not the case, but doing the check is still important for obvious reasons. and this version of the patch differs in that it uses a helper function to clarify the code, and does all the checks in pages (instead of bytes) in order to avoid overflows when doing "<< PAGE_SHIFT" etc. Acked-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

But BIOS EBDA pointers are at most 1K large. _if_ the Rio code truly extends upon the customary EBDA size it needs to iounmap() this memory and ioremap() it larger, once it knows it from the generic descriptors that a Rio system is around.

2008-09-23dock: introduce .uevent for devices in dock, eg libataShaohua Li
dock's uevent reported itself, not ata. It might be difficult to find an ata device just according to a dock. This patch introduces docking ops for each device in a dock. when docking, dock driver can send device specific uevent. This should help dock station too (not just bay) Signed-off-by: Shaohua Li <shaohua.li@intel.com> Acked-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Len Brown <len.brown@intel.com>
2008-09-16PCI: fix compiler warnings in pci_get_subsys()Greg KH
pci_get_subsys() changed in 2.6.26 so that the from pointer is modified when the call is being invoked, so fix up the 'const' marking of it that the compiler is complaining about.
