2008-02-07drivers/edac: pci: broken parity regressionBryan Boatright
Using the EDAC code in kernel.org kernel version 2.6.23.8 I am seeing the following problem: In the kernel there is a pci device attribute located in sysfs that is checked by the EDAC PCI scanning code. If that attribute is set, PCI parity/error scannining is skipped for that device. The attribute is: broken_parity_status as is located in /sys/devices/pci<XXX>/0000:XX:YY.Z directorys for PCI devices. I don't think this check was actually implemented. I have a misbehaved card that reports a parity error every 1000 ms: Nov 25 07:28:43 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0 Nov 25 07:28:44 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0 Nov 25 07:28:45 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0 Setting that card's broken_parity_status bit did not mask the error: echo "1" > /sys/bus/pci/devices/0000:05:01.0/broken_parity_status I looked through the EDAC code and did not readily see any reference to broken_parity_status at all (which makes sense based on the behavior I am seeing). I applied the following patch as a proof-of-concept and now EDAC's PCI parity error reporting behaves as documented: bryan Good regression find, bryan. It used to work. sigh. I added more logic to your patch, for more coverage of the error.

2008-01-24Kobject: convert drivers/* from kobject_unregister() to kobject_put()Greg Kroah-Hartman
There is no need for kobject_unregister() anymore, thanks to Kay's kobject cleanup changes, so replace all instances of it with kobject_put(). Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-01-24Kobject: change drivers/edac to use kobject_init_and_addGreg Kroah-Hartman
Stop using kobject_register, as this way we can control the sending of the uevent properly, after everything is properly initialized. Acked-by: Doug Thompson <dougthompson@xmission.com> Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-26drivers/edac: fix edac_pci sysfsDoug Thompson
This patch fixes sysfs exit code for the EDAC PCI device in a similiar manner and the previous fixes for EDAC_MC and EDAC_DEVICE. It removes the old (and incorrect) completion model and uses reference counts on per instance kobjects and on the edac core module. This pattern was applied to the edac_mc and edac_device code, but the EDAC PCI code was missed. In addition, this fixes a system hang after a low level driver was unloaded. (A cleanup function was called twice, which really screwed things up) Cc: Greg KH <greg@kroah.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Doug Thompson <dougthompson@xmission.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-07-19drivers/edac: cleanup spaces-gotos after Lindent messupDouglas Thompson
This patch fixes some remnant spaces inserted by the use of Lindent. Seems Lindent adds some spaces when it shoulded. These have been fixed. In addition, goto targets have issues, these have been fixed in this patch.

2007-07-19drivers/edac: mod use edac_core.hDouglas Thompson
In the refactoring of edac_mc.c into several subsystem files, the header file edac_mc.h became meaningless. A new header file edac_core.h was created. All the files that previously included "edac_mc.h" are changed to include "edac_core.h".

2007-07-19drivers/edac: split out functions to unique filesDouglas Thompson
This is a large patch to refactor the original EDAC module in the kernel and to break it up into better file granularity, such that each source file contains a given subsystem of the EDAC CORE. Originally, the EDAC 'core' was contained in one source file: edac_mc.c with it corresponding edac_mc.h file. Now, there are the following files: edac_module.c The main module init/exit function and other overhead edac_mc.c Code handling the edac_mc class of object edac_mc_sysfs.c Code handling for sysfs presentation edac_pci_sysfs.c Code handling for PCI sysfs presentation edac_core.h CORE .h include file for 'edac_mc' and 'edac_device' drivers edac_module.h Internal CORE .h include file This forms a foundation upon which a later patch can create the 'edac_device' class of object code in a new file 'edac_device.c'.
