* PCI ACPI: Added a function to register _OSC with only PCIe devices.Andrew Patterson2008-02-01
| | | | | | | | | | | | | | The function pci_osc_support_set() traverses every root bridge when checking for _OSC support for a capability. It quits as soon as it finds a device/bridge that doesn't support the requested capability. This won't work for systems that have mixed PCI and PCIe bridges when checking for PCIe features. I split this function into two -- pci_osc_support_set() and pcie_osc_support_set(). The latter is used when only PCIe devices should be traversed.

* PCI: fix AER driver error informationZhang, Yanmin2007-07-11
| | | | | | | | | | | | | | | | | | | | Below patch fixes aer driver error information and enables aer driver although CONFIG_ACPI=n. As a matter of fact, the new patch is created from below 2 patches plus a minor patch apply fuzz fixing. Because the second patch fixed a compilation error introduced by the first patch, I merge them to facilitate bisect. 1) http://marc.info/?l=linux-kernel&m=117783233918191&w=2; 2) http://marc.info/?l=linux-mm-commits&m=118046936720790&w=2 Signed-off-by: Zhang Yanmin <yanmin.zhang@intel.com> Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* pci: clear osc support flags if no _OSC methodKristen Carlson Accardi2006-12-01
| | | | | | | | | | | | | | | | | | | | | So it looks like pci aer code will call pci_osc_support_set to tell the firmware about OSC_EXT_PCI_CONFIG_SUPPORT flag. that causes ctrlset_buf[OSC_SUPPORT_TYPE] to evaluate to true when pciehp calls pci_osc_control_set() is called (to attempt to use OSC to gain native pcie control from firmware), regardless of whether or not _OSC was actually successfully executed. That causes this section of code: if (ctrlset_buf[OSC_SUPPORT_TYPE] && ((global_ctrlsets & ctrlset) != ctrlset)) { return AE_SUPPORT; } to be hit. This patch will reset the OSC_SUPPORT_TYPE field if _OSC fails, and then would allow pciehp to go ahead and try to run _OSC again.

* [PATCH] PCI ACPI: Rename the functions to avoid multiple instances.Muthu Kumar2006-06-21
| | | | | | | | | | There were two instances of pci_acpi_init(), one in drivers/pci/pci-acpi.c and another in arch/i386/pci/acpi.c. Rename the one in pci-acpi.c and make it consistent with other names in the same file. Signed-off-by: Muthukumar R <muthur@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] pci: correctly allocate return buffers for osc callsKristen Accardi2006-05-21
| | | | | | | | | | | | | | | | | | The OSC set and query functions do not allocate enough space for return values, and set the output buffer length to a false, too large value. This causes the acpi-ca code to assume that the output buffer is larger than it actually is, and overwrite memory when copying acpi return buffers into this caller provided buffer. In some cases this can cause kernel oops if the memory that is overwritten is a pointer. This patch will change these calls to use a dynamically allocated output buffer, thus allowing the acpi-ca code to decide how much space is needed.

* [PATCH] pciehp: request control of each hotplug controller individuallyrajesh.shah@intel.com2005-11-10
| | | | | | | | | | | | | This patch tweaks the way pciehp requests control of the hotplug hardware from BIOS. It now tries to invoke the ACPI _OSC method for a specific hotplug controller only, rather than walking the entire acpi namespace invoking all possible _OSC methods under all host bridges. This allows us to gain control of each hotplug controller individually, even if BIOS fails to give us control of some other hotplug controller in the system.

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!
