From 011d8261117249eab97bc86a8e1ac7731e03e319 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Mon, 27 Mar 2017 11:33:02 +0200 Subject: RAS: Add a Corrected Errors Collector Introduce a simple data structure for collecting correctable errors along with accessors. More detailed description in the code itself. The error decoding is done with the decoding chain now and mce_first_notifier() gets to see the error first and the CEC decides whether to log it and then the rest of the chain doesn't hear about it - basically the main reason for the CE collector - or to continue running the notifiers. When the CEC hits the action threshold, it will try to soft-offine the page containing the ECC and then the whole decoding chain gets to see the error.
