edac: i5000_edac critical fix panic out of bounds

2010-01-28T23:20:01+00:00

commit 118f3e1afd5534c15f9701f33514186cfc841a27 upstream.

EDAC MC0: INTERNAL ERROR: channel-b out of range (4 >= 4)
Kernel panic - not syncing: EDAC MC0: Uncorrected Error  (XEN) Domain 0 crashed: 'noreboot' set - not rebooting.

This happens because FERR_NF_FBD bit 28 is not updated on i5000.  Due to
that, both bits 28 and 29 may be equal to one, returning channel = 3.  As
this value is invalid, EDAC core generates the panic.

edac: fix enabling of polling cell module

2008-12-13T23:29:18+00:00

commit 992b692dcf43612be805465ca4b76f434c715023 upstream.

The edac driver on cell turned out to be not enabled because of a missing
op_state.  This patch introduces it.  Verified to work on top of Ben's
next branch.

edac cell: fix incorrect edac_mode

2008-10-25T21:32:36+00:00

commit 3b274f44d2ca05f719fe39947b6a5293a2dbd8fd upstream

The cell_edac driver is setting the edac_mode field of the csrow's to an
incorrect value, causing the sysfs show routine for that field to go out
of an array bound and Oopsing the kernel when used.

edac: e752x fix too loud on nonmemory errors

2008-07-25T17:53:49+00:00

This module harvests more than just memory errors, it also harvests
various bus and dma errors that the Chipset detects.  Previously, it would
report all such errors, which would cause output to be TOO loud.

This patches therefore adds a parameter which is used to turn off
NON-MEMORY error reports by default.  Or the reporting can be enabled via
the parameter

Also did code style cleanup: less than 80 characters per line rule

edac: core fix added newline to sysfs dimm labels

2008-07-25T17:53:49+00:00

The channel DIMM label does not seem to be used much in the edac code.
However, where it is used (in the core code), it is assumed to not have a
newline embedded.  This leaves the sysfs file newline free which looks
funny when cat'ing it.  Here we just add the trailing newline to the sysfs
chX_dimm_label output...

[Doug Thompson note: the DIMM label is one of the primary uses of EDAC.
User space daemon scripts, edac-utils@sourceforge, populate the DIMM label
fields, via /sys/devices/system/edac attributes, with the silk screen
labels of the motherboard in use.  dmidecode access BIOS tables, but BIOS
tables are well known to be incorrect and useless in these respects.
edac-utils will strip off any newlines before its use of the output, when
displaying DIMM slot silk screen labels.
