RAS: Build debugfs.o only when enabled in Kconfig

2019-08-08T15:44:02+00:00

In addition, the 0day bot reported this build error: >> drivers/ras/debugfs.c:10:5: error: redefinition of 'ras_userspace_consumers' int ras_userspace_consumers(void) ^~~~~~~~~~~~~~~~~~~~~~~ In file included from drivers/ras/debugfs.c:3:0: include/linux/ras.h:14:19: note: previous definition of 'ras_userspace_consumers' was here static inline int ras_userspace_consumers(void) { return 0; } ^~~~~~~~~~~~~~~~~~~~~~~ for a riscv-specific .config where CONFIG_DEBUG_FS is not set. Fix all that by making debugfs.o depend on that define.

RAS: Add a Corrected Errors Collector

2017-03-28T06:54:48+00:00

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.

RAS, debugfs: Add debugfs interface for RAS subsystem

2014-06-25T18:22:03+00:00

Implement a new debugfs interface for RAS susbsystem. A file named daemon_active is added there accordingly. This file is used to track if user space daemon accesses perf/trace interface or not. One can track which daemon opens it via "lsof /path/to/debugfs/ras/daemon_active".

trace, RAS: Add basic RAS trace event

2014-06-23T17:12:19+00:00

To avoid confuision and conflict of usage for RAS related trace event, add an unified RAS trace event stub. Start a RAS subsystem menu which will be fleshed out in time, when more features get added to it.
