edac: add support for error type "Info"

2013-02-21T17:16:27+00:00

The CPER spec defines a forth type of error: informational
logs. Add support for it at the edac API and at the
trace event interface.

edac: reduce stack pressure by using a pre-allocated buffer

2013-02-21T16:48:45+00:00

The number of variables at the stack is too big.
Reduces the stack usage by using a pre-allocated error
buffer.

edac: add a new memory layer type

2013-02-21T14:06:37+00:00

There are some cases where the memory controller layout is
completely hidden. This is the case of firmware-driven error
code, like the one provided by GHES. Add a new layer to be
used on such memory error report mechanisms.

edac: edac_mc no longer deals with kobjects directly

2012-12-21T10:00:02+00:00

There are no more embedded kobjects in struct mem_ctl_info. Remove a header and
a comment that does not reflect the code anymore.

EDAC: Fix csrow size reported in sysfs

2012-11-28T10:54:40+00:00

On csrow-based memory controllers, we combine the csrow size from both
channels and there's no need to do that again in csrow_size_show which
leads to double the size of a csrow.

Fix it.

EDAC: Add memory controller flags

2012-11-28T10:48:04+00:00

The first flag is ->csbased and will be used in common EDAC code later.

edac: allow specifying the error count with fake_inject

2012-06-27T12:01:30+00:00

In order to test if the error counters are properly incremented,
add a way to specify how many errors were generated by a trace.

edac: change the mem allocation scheme to make Documentation/kobject.txt happy

2012-06-11T16:23:45+00:00

Kernel kobjects have rigid rules: each container object should be
dynamically allocated, and can't be allocated into a single kmalloc.

EDAC never obeyed this rule: it has a single malloc function that
allocates all needed data into a single kzalloc.

As this is not accepted anymore, change the allocation schema of the
EDAC *_info structs to enforce this Kernel standard.

edac: Add debufs nodes to allow doing fake error inject

2012-06-11T16:23:43+00:00

Sometimes, it is useful to have a mechanism that generates fake
errors, in order to test the EDAC core code, and the userspace
tools.

Provide such mechanism by adding a few debugfs nodes.
