2007-07-17Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki
Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

2007-05-08Fix 82875 PCI setupJohn Feeney
The 82875 EDAC driver enables an otherwise-hidden PCI device, but doesn't register it as a PCI device properly. Therefore, the device list in /proc/bus/pci/devices is different than the tree in /sys/bus/pci. This usually manifests as the X server failing to start, since it expects the two lists to be consistent.

2007-02-12[PATCH] EDAC: Add memory scrubbing controls API to coreFrithiof Jensen
This is an attempt of providing an interface for memory scrubbing control in EDAC. This patch modifies the EDAC Core to provide the Interface for memory controller modules to implment. The following things are still outstanding: - K8 is the first implemenation, The patch provide a method of configuring the K8 hardware memory scrubber via the 'mcX' sysfs directory. There should be some fallback to a generic scrubber implemented in software if the hardware does not support scrubbing. Or .. the scrubbing sysfs entry should not be visible at all. - Only works with SDRAM, not cache, The K8 can scrub cache and l2cache also - but I think this is not so useful as the cache is busy all the time (one hopes). One would also expect that cache scrubbing requires hardware support. - Error Handling, I would like that errors are returned to the user in "terms of file system". - Presentation, I chose Bandwidth in Bytes/Second as a representation of the scrubbing rate for the following reasons: I like that the sysfs entries are sort-of textual, related to something that makes sense instead of magical values that must be looked up. "My People" wants "% main memory scrubbed per hour" others prefer "% memory bandwidth used" as representation, "bandwith used" makes it easy to calculate both versions in one-liner scripts. If one later wants to scrub cache, the scaling becomes wierd for K8 changing from "blocks of 64 byte memory" to "blocks of 64 cache lines" to "blocks of 64 bit". Using "bandwidth used" makes sense in all three cases, (I.M.O. anyway ;-). - Discovery, There is no way to discover the possible settings and what they do without reading the code and the documentation. *I* do not know how to make that work in a practical way. - Bugs(??), other tools can set invalid values in the memory scrub control register, those will read back as '-1', requiring the user to reset the scrub rate. This is how *I* think it should be. - Afflicting other areas of code, I made changes to edac_mc.c and edac_mc.h which will show up globally - this is not nice, it would be better that the memory scrubbing fuctionality and interface could be entirely contained within the memory controller it applies to. Frithiof Jensen edac_mc.c and its .h file is a CORE helper module for EDAC driver modules. This provides the abstraction for device specific drivers.

2006-07-10[PATCH] Fix and enable EDAC sysfs operationDoug Thompson
When EDAC was first introduced into the kernel it had a sysfs interface, but due to some problems it was disabled in 2.6.16 and remained disabled in 2.6.17. With feedback, several of the control and attribute files of that interface had some good constructive feedback. PCI Blacklist/Whitelist was a major set which has design issues and it has been removed in this patch. Instead of storing PCI broken parity status in EDAC, it has been moved to the pci_dev structure itself by a previous PCI patch. A future patch will enable that feature in EDAC by utilizing the pci_dev info. The sysfs is now enabled in this patch, with a minimal set of control and attribute files for examining EDAC state and for enabling/disabling the memory and PCI operations. The Documentation for EDAC has also been updated to reflect the new state of EDAC operation.

2006-06-30[PATCH] EDAC: mc numbers refactor 1-of-2Doug Thompson
Remove add_mc_to_global_list(). In next patch, this function will be reimplemented with different semantics. 1 Reimplement add_mc_to_global_list() with semantics that allow the caller to determine the ID number for a mem_ctl_info structure. Then modify edac_mc_add_mc() so that the caller specifies the ID number for the new mem_ctl_info structure. Platform-specific code should be able to assign the ID numbers in a platform-specific manner. For instance, on Opteron it makes sense to have the ID of the mem_ctl_info structure match the ID of the node that the memory controller belongs to. 2 Modify callers of edac_mc_add_mc() so they use the new semantics.

2006-03-26[PATCH] EDAC: kobject/sysfs fixesDave Peterson
- After we unregister a kobject, wait for our kobject release method to call complete(). This causes us to wait until the kobject reference count reaches 0. Otherwise, a task accessing the EDAC sysfs interface can hold the reference count above 0 until after the EDAC module has been unloaded. When the reference count finally drops to 0, this will result in an attempt to call our release method inside the EDAC module after the module has already been unloaded. This isn't the best fix, since a process can get stuck sleeping forever uninterruptibly if the user does the following: rmmod my_module < /sys/my_sysfs/file I'll go back and implement a better fix later. However this should be ok for now. - Call edac_remove_sysfs_mci_device() from edac_mc_del_mc() rather than from edac_mc_free(). Since edac_mc_add_mc() calls edac_create_sysfs_mci_device(), edac_mc_del_mc() should call edac_remove_sysfs_mci_device(). Signed-off-by: David S.

2006-03-11[PATCH] edac: disable a few sysfs files to avoid them becoming an ABIArjan van de Ven
Disable (via ugly #if 0's) the 3 sysfs files that I think by now we all agree are very much wrong. These files shouldn't become part of the ABI by the 2.6.16 release, so I rather have this minimal patch merged to disable them for now, the real fix can then come during the 2.6.17 devel window.

EDAC is still causing a few problems and the code is relatively green. Mark it as experimental until thing settle down. Also, provide some documentation pointers in Kconfig help.

By including version.h edac_mc was rebuilding on every incremental build. Which defeats the point of incremental builds. Signed-off-by: Eric W.

2006-01-18[PATCH] EDAC: core EDAC support codeAlan Cox
This is a subset of the bluesmoke project core code, stripped of the NMI work which isn't ready to merge and some of the "interesting" proc functionality that needs reworking or just has no place in kernel. It requires no core kernel changes except the added scrub functions already posted. The goal is to merge further functionality only after the core code is accepted and proven in the base kernel, and only at the point the upstream extras are really ready to merge. From: doug thompson <norsk5@xmission.com> This converts EDAC to sysfs and is the final chunk neccessary before EDAC has a stable user space API and can be considered for submission into the base kernel.
