2008-10-22PCI: Workaround invalid P2P bridge bus numbersBenjamin Herrenschmidt
Some firmware fail to properly configure P2P bridges, leaving them with invalid bus numbers. In some cases, this happens on some embedded 4xx boards as the result of the kernel allocating different bus space than the firmware does to host bridges while not setting pcibios_assign_all_busses() for various reasons. In other cases, it can just be bogus firmware. This adds some sanity checking to the PCI probing code. If a bridge is found whose primary bus number doesn't match the bus it's sitting on, or whose secondary bus number not strictly above it's primary bus number, then the bridge bus numbers are deconfigured in the first pass of pci_scan_bridge() to be re-assigned in the second pass.

2008-10-22PCI Hotplug: fakephp: add duplicate slot name debuggingAlex Chiang
The PCI core now manages slot names on behalf of slot detection and slot hotplug drivers, including the handling of duplicate slot names. We can use the fakephp driver to help test the new functionality. Add a 'dup_slots' module param to force fakephp to create multiple slots with the same name. We can then verify that the PCI core correctly renamed the slots. sapphire:/sys/bus/pci/slots # modprobe fakephp dup_slots sapphire:/sys/bus/pci/slots # ls fake fake-10 fake-3 fake-5 fake-7 fake-9 fake-1 fake-2 fake-4 fake-6 fake-8 Cc: kristen.c.accardi@intel.com Cc: matthew@wil.cx Acked-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2008-10-22PCI: prevent duplicate slot namesAlex Chiang
Prevent callers of pci_create_slot() from registering slots with duplicate names. This condition occurs most often when PCI hotplug drivers are loaded on platforms with broken firmware that assigns identical names to multiple slots. We now rename these duplicate slots on behalf of the user. If firmware assigns the name N to multiple slots, then: The first registered slot is assigned N The second registered slot is assigned N-1 The third registered slot is assigned N-2 etc. This is the permanent fix mentioned in earlier commits d6a9e9b4 and 167e782e (shpchp/pciehp: Rename duplicate slot name...). We take advantage of the new 'hotplug' parameter in pci_create_slot() to prevent a slot create/rename race between hotplug drivers and detection drivers. Scenario A: hotplug driver detection driver -------------- ---------------- pci_create_slot(hotplug=set) pci_create_slot(hotplug=NULL) The hotplug driver creates the slot with its desired name, and then releases the semaphore. Now, the detection driver tries to create the same slot, but it already exists. We don't care about renaming, so return the existing slot. Scenario B: hotplug driver detection driver -------------- ---------------- pci_create_slot(hotplug=NULL) pci_create_slot(hotplug=set) The detection driver creates the slot with name "X". Then the hotplug driver tries to create the same slot, but wants the name "Y" instead. We detect that we're trying to create the same slot and that we also want a rename, so rename the slot to "Y" and return. Scenario C: hotplug driver hotplug driver -------------- ---------------- pci_create_slot(hotplug=set) pci_create_slot(hotplug=set) Two separate hotplug drivers are attempting to claim the slot and are passing valid hotplug_slot args to pci_create_slot(). We detect that the slot already has a ->hotplug callback, prevent a rename, and return -EBUSY.

2008-10-22PCI: update pci_create_slot() to take a 'hotplug' paramAlex Chiang
Slot detection drivers can co-exist with hotplug drivers. The names of the detected/claimed slots may be different depending on module load order. For legacy reasons, we need to allow hotplug drivers to override the slot name if a detection driver is loaded first (and they find the same slots). Creating and overriding slot names should be an atomic operation, otherwise you get a locking nightmare as various drivers race to call pci_create_slot(). pci_create_slot() is already serialized by grabbing the pci_bus_sem. We update the API and add a 'hotplug' param, which is: set if the caller is a hotplug driver NULL if the caller is a detection driver pci_create_slot() does not actually use the 'hotplug' parameter in this patch. A later patch will add the logic that uses it.

2008-10-22PCI: add support for function level resetSheng Yang
Sometimes, it's necessary to enable software's ability to quiesce and reset endpoint hardware with function-level granularity, so provide support for it. The patch implement Function Level Reset(FLR) feature following PCI-e spec. And this is the first step. We would add more generic method, like D0/D3, to allow more devices support this function. The patch contains two functions. pcie_reset_function() is the new driver API, and, contains some action to quiesce a device. The other function is a helper: pcie_execute_reset_function() just executes the reset for a particular device function. Current the usage model is in KVM. Function reset is necessary for assigning device to a guest, or moving it between partitions. For Function Level Reset(FLR), please refer to PCI Express spec chapter 6.6.2.

2008-10-22PCI: Fix reference counting bugMatthew Wilcox
pci_get_subsys() will decrement the reference count of the device that it starts searching from. Unfortunately, the pci_find_device() interface will already have decremented the reference count of the device earlier, so the device will end up losing all reference counts and be freed. We can fix this by incrementing the reference count of the device to start searching from before calling pci_get_subsys().

In current pci_osc_control_set() implementation, once the _OSC control field is queried, it is never queried again. But the query result can change depending on the _OSC support field. For example, if PCI Express Native Hot Plug control depends on ASPM support on a certain platform, a PCI Express Native Hot Plug Control query would fail before the ASPM driver was loaded, but it would succeed if the ASPM driver was loaded first. Therefore, pci_osc_control_set() should query the _OSC control field every time.

2008-10-20Remove empty imacfb.c fileLinus Torvalds
Commit 7c08c9ae0c145807c0dae4a55f240fa3d4fd5262 ("efifb/imacfb consolidation + hardware support") claimed to remove imacfb entirely and merge its DMI table into the efifb driver. So far so good, but the diff actually ended up just generating an empty file instead of removing it. [ Technical reason: the patch header looked like diff -puN drivers/video/imacfb.c~efifb-imacfb-consolidation-hardware-support drivers/video/imacfb.c --- a/drivers/video/imacfb.c~efifb-imacfb-consolidation-hardware-support +++ a/drivers/video/imacfb.c @@ -1,376 +0,0 @@ which git will think is a truncation, not a delete. Git wants to see a target of /dev/null to consider it a delete. ] So remove it properly. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-10-20PCI: fix AER capability checkYu Zhao
The 'use pci_find_ext_capability everywhere' cleanup brought a new bug, which makes the AER stop working. Fix it by actually using find_ext_cap instead of just find_cap. Drop the unused config space size define while we're at it. Signed-off-by: Yu Zhao <yu.zhao@intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2008-10-20PCI: use pci_find_ext_capability everywhereJesse Barnes

2008-10-20PCI hotplug: fix get_##name return value problemKenji Kaneshige
The commit 356a9d6f3dd283f83861adf1ac909879f0e66411 (PCI: fix hotplug get_##name return value problem) doesn't seem to be merged properly. Because of this, PCI hotplug no longer works (Read/Write PCI hotplug files always returns -ENODEV). This patch fixes wrong check of try_module_get() return value check in get_##name().

2008-10-20PCI: Add ability to mmap legacy_io on some platformsBenjamin Herrenschmidt
This adds the ability to mmap legacy IO space to the legacy_io files in sysfs on platforms that support it. This will allow to clean up X to use this instead of /dev/mem for legacy IO accesses such as those performed by Int10. While at it I moved pci_create/remove_legacy_files() to pci-sysfs.c where I think they belong, thus making more things statis in there and cleaned up some spurrious prototypes in the ia64 pci.h file Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2008-10-20PCI: support PCIe ARI capabilityYu Zhao
This patch adds support for PCI Express Alternative Routing-ID Interpretation (ARI) capability. The ARI capability extends the Function Number field of the PCI Express Endpoint by reusing the Device Number which is otherwise hardwired to 0. With ARI, an Endpoint can have up to 256 functions.
