aerdrv: Move cper_print_aer() call out of interrupt context

2013-05-30T17:51:20Z

The following warning was seen on 3.9 when a corrected PCIe error was being handled by the AER subsystem. WARNING: at .../drivers/pci/search.c:214 pci_get_dev_by_id+0x8a/0x90() This occurred because a call to pci_get_domain_bus_and_slot() was added to cper_print_pcie() to setup for the call to cper_print_aer(). The warning showed up because cper_print_pcie() is called in an interrupt context and pci_get* functions are not supposed to be called in that context. The solution is to move the cper_print_aer() call out of the interrupt context and into aer_recover_work_func() to avoid any warnings when calling pci_get* functions.

aerdrv: Enhanced AER logging

2013-01-03T22:34:06Z

This patch will provide a more reliable and easy way for user-space applications to have access to AER logs rather than reading them from the message buffer. It also provides a way to notify user-space when an AER event occurs. The aer driver is updated to generate a trace event of function 'aer_event' when a PCIe error is reported over the AER interface. The trace event was added to both the interrupt based aer path and the firmware first path. Signed-off-by: Lance Ortiz Acked-by: Mauro Carvalho Chehab Acked-by: Boris Petkov Signed-off-by: Tony Luck

PCI: PCIe AER: add aer_recover_queue

2011-07-22T15:25:37Z

In addition to native PCIe AER, now APEI (ACPI Platform Error Interface) GHES (Generic Hardware Error Source) can be used to report PCIe AER errors too. To add support to APEI GHES PCIe AER recovery, aer_recover_queue is added to export the recovery function in native PCIe AER driver. Recoverable PCIe AER errors are reported via NMI in APEI GHES. Then APEI GHES uses irq_work to delay the error processing into an IRQ handler. But PCIe AER recovery can be very time-consuming, so aer_recover_queue, which can be used in IRQ handler, delays the real recovery action into the process context, that is, work queue.

ACPI, APEI, Add PCIe AER error information printing support

2011-03-22T02:59:08Z

The AER error information printing support is implemented in drivers/pci/pcie/aer/aer_print.c. So some string constants, functions and macros definitions can be re-used without being exported. The original PCIe AER error information printing function is not re-used directly because the overall format is quite different. And changing the original printing format may make some original users' scripts broken. Signed-off-by: Huang Ying CC: Jesse Barnes CC: Zhang Yanmin Signed-off-by: Len Brown

PCI: fix AER capability check

2008-10-20T18:01:52Z

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 Signed-off-by: Jesse Barnes

PCI: use pci_find_ext_capability everywhere

PCI aer: add pci_cleanup_aer_correct_aer_status

2007-07-11T23:02:08Z

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. Signed-off-by: Stephen Hemminger Acked-by: Zhang Yanmin Signed-off-by: Greg Kroah-Hartman
