2010-05-11PCI: aerdrv: introduce default_downstream_reset_linkHidetoshi Seto1-7/+8
I noticed that when I inject a fatal error to an endpoint via aer-inject, aer_root_reset() is called as reset_link for a downstream port at upstream of the endpoint: pcieport 0000:00:06.0: AER: Uncorrected (Fatal) error received: id=5401 : pcieport 0000:52:02.0: Root Port link has been reset It externally appears to be working, but internally issues some accesses to PCI_ERR_ROOT_COMMAND/STATUS registers that is for root port so not available on downstream port. This patch introduces default_downstream_reset_link that is a version of aer_root_reset() with no accesses to root port's register. It is used for downstream ports that has no reset_link function its specific. This patch also updates related description in pcieaer-howto.txt. Some minor fixes are included.

2009-06-16PCI AER: software error injectionHuang Ying1-1/+1
Debugging PCIE AER code can be very difficult because it is hard to trigger various real hardware errors. This patch provide a software based error injection tool, which can fake various PCIE errors with a user space helper tool named "aer-inject". Which can be gotten from: http://www.kernel.org/pub/linux/kernel/people/yhuang/ The patch fakes AER error by faking some PCIE AER related registers and an AER interrupt for specified the PCIE device.
