2011-09-27doc: fix broken referencesPaul Bolle1-1/+1
There are numerous broken references to Documentation files (in other Documentation files, in comments, etc.). These broken references are caused by typo's in the references, and by renames or removals of the Documentation files. Some broken references are simply odd. Fix these broken references, sometimes by dropping the irrelevant text they were part of. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

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.
