* | | | amd64_edac: Fix driver module removalBorislav Petkov2010-09-271-0/+3
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | f4347553b30ec66530bfe63c84530afea3803396 removed the edac polling mechanism in favor of using a notifier chain for conveying MCE information to edac. However, the module removal path didn't test whether the driver had setup the polling function workqueue at all and the rmmod process was hanging in the kernel at try_to_del_timer_sync() in the cancel_delayed_work() path, trying to cancel an uninitialized work struct. Fix that by adding a balancing check to the workqueue removal path. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
* | | amd64_edac: Do not report error overflow as a separate errorBorislav Petkov2010-08-262-13/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the Overflow MCi_STATUS bit is set, EDAC reports the lost error with a "no information available" message which often puzzles users parsing the dmesg. This doesn't make much sense since this error has been lost anyway so no need for reporting it separately. Thus, report the overflow bit setting in the MCE dump instead. While at it, remove reporting of MiscV and ErrorEnable (en) which are superfluous. Now it looks like this: [ 1501.650024] MC4_STATUS: Corrected error, other errors lost: yes, CPU context corrupt: no, CECC Error [ 1501.666887] Northbridge Error, node 2 Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
