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
Remove some open coded (and buggy) versions of pci_find_ext_capability in favor of the real routine in the PCI core.

2007-07-11PCI aer: add pci_cleanup_aer_correct_aer_statusStephen Hemminger
Function to clear bogus correctable errors. Analog to pci_aer_uncorrect_are_status. The Marvell chips seem to start out with a bogus value that needs to be cleared. Yanmin ported it to 2.6.22-rc4 by fixing a fuzz patch applying info.

2006-09-26PCI-Express AER implemetation: AER core and aerdriverZhang, Yanmin
Patch 3 implements the core part of PCI-Express AER and aerdrv port service driver. When a root port service device is probed, the aerdrv will call request_irq to register irq handler for AER error interrupt. When a device sends an PCI-Express error message to the root port, the root port will trigger an interrupt, by either MSI or IO-APIC, then kernel would run the irq handler. The handler collects root error status register and schedules a work. The work will call the core part to process the error based on its type (Correctable/non-fatal/fatal). As for Correctable errors, the patch chooses to just clear the correctable error status register of the device. As for the non-fatal error, the patch follows generic PCI error handler rules to call the error callback functions of the endpoint's driver. If the device is a bridge, the patch chooses to broadcast the error to downstream devices. As for the fatal error, the patch resets the pci-express link and follows generic PCI error handler rules to call the error callback functions of the endpoint's driver. If the device is a bridge, the patch chooses to broadcast the error to downstream devices. Signed-off-by: Zhang Yanmin <yanmin.zhang@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
