2007-07-19drivers/edac: fix edac_device init apisDoug Thompson
Refactoring of sysfs code necessitated the refactoring of the edac_device_alloc() and edac_device_add_device() apis, of moving the index value to the alloc() function. This patch alters the in tree drivers to utilize this new api signature. Having the index value performed later created a chicken-and-the-egg issue. Moving it to the alloc() function allows for creating the necessary sysfs entries with the proper index number Cc: Alan Cox alan@lxorguk.ukuu.org.uk Signed-off-by: Doug Thompson <dougthompson@xmission.com> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-07-19drivers/edac: fix leaf sysfs attributeDouglas Thompson
This patch fixes and enhances the driver level set of sysfs attributes that can be added to the 'block' level of an edac_device type of driver. There is a controller information structure, which contains one or more instances of device. Each instance will have one or more blocks of device specific counters. This patch fixes the ability to have more detailed attributes/controls for each of the 'blocks', providing for the addition of controls/attributes from the low level driver to user space via sysfs.

2007-07-19drivers/edac: fix edac_device semaphore to mutexDoug Thompson
A previous patch changed the edac_mc src file from semaphore usage to mutex This patch changes the edac_device src file as well, from semaphore use to mutex operation. Use a mutex primitive for mutex operations, as it does not require a semaphore Cc: Alan Cox alan@lxorguk.ukuu.org.uk Signed-off-by: Doug Thompson <dougthompson@xmission.com> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-07-19drivers/edac: mod edac_opt_state_to_string functionDouglas Thompson
Refactored the function edac_op_state_toString() to be edac_op_state_to_string() for consistent style, and its callers Signed-off-by: Douglas 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: mod edac_align_ptr functionDouglas Thompson
Refactor the edac_align_ptr() function to reduce the noise of casting the aligned pointer to the various types of data objects and modified its callers to its new signature Signed-off-by: Douglas 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: device output clenaupDouglas Thompson
The error handling output strings needed to be refactored for better displaying of the error informaton. Also needed to added offset_value for output as well Signed-off-by: Douglas 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 workq ifdefsDouglas Thompson
The origin of this code comes from patches at sourceforge, that allow EDAC to be updated to various kernels. With kernel version 2.6.20 a new workq system was installed, thus the patches needed to be modified based on the kernel version. For submitting to the latest kernel.org those #ifdefs are removed Signed-off-by: Douglas 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: add dev_name getter functionDave Jiang
Move dev_name() macro to a more generic interface since it's not possible to determine whether a device is pci, platform, or of_device easily. Now each low level driver sets the name into the control structure, and the EDAC core references the control structure for the information. Better abstraction.

2007-07-19drivers/edac: add edac_device classDouglas Thompson
This patch adds the new 'class' of object to be managed, named: 'edac_device'. As a peer of the 'edac_mc' class of object, it provides a non-memory centric view of an ERROR DETECTING device in hardware. It provides a sysfs interface and an abstraction for varioius EDAC type devices. Multiple 'instances' within the class are possible, with each 'instance' able to have multiple 'blocks', and each 'block' having 'attributes'. At the 'block' level there are the 'ce_count' and 'ue_count' fields which the device driver can update and/or call edac_device_handle_XX() functions. At each higher level are additional 'total' count fields, which are a summation of counts below that level. This 'edac_device' has been used to capture and present ECC errors which are found in a a L1 and L2 system on a per CORE/CPU basis.
