* drivers/edac: mod race fix i82875pJason Uhlenkott2007-07-191-6/+7
| | | | | | | | | | | | | | | | | If ERRSTS indicates that there's no error then we don't need to bother reading the other registers. In addition to making the common case faster, this actually fixes a small race where we don't see an error but we clear the error bits anyway, potentially wiping away info on an error that happened in the interim (or where a CE arrives between the first and second read of ERRSTS, causing us to falsely claim "UE overwrote CE").

* drivers/edac: add mips and ppc visibilityDouglas Thompson2007-07-191-4/+3
| | | | | | | | | | | | | | | 1) Remove an old CVS ID string 2) change EDAC from a tristate option to a simple bool option 3) In addition to the X86 arch, PPC and MIPS also have drivers in the submission queue. This patch turns on the EDAC flag for those archs. Each driver will have its respective 'depends on ARCH' set.

| | | | | | | | | | | | | | | | | | | Provides a way for NMI reported errors on x86 to notify the EDAC subsystem pending ECC errors by writing to a software state variable. Here's the reworked patch. I added an EDAC stub to the kernel so we can have variables that are in the kernel even if EDAC is a module. I also implemented the idea of using the chip driver to select error detection mode via module parameter and eliminate the kernel compile option. Please review/test. Thx!

* drivers/edac: add edac_device classDouglas Thompson2007-07-198-60/+1936
| | | | | | | | | | | | | | | | | | | | | | | 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.

* drivers/edac: split out functions to unique filesDouglas Thompson2007-07-198-1776/+1932
| | | | | | | | | | | | | | | | | | | | | | | | | 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'.

* lguest: the guest codeRusty Russell2007-07-195-0/+878
| | | | | | | | | | | | | | | | | | | | | | | | | lguest is a simple hypervisor for Linux on Linux. Unlike kvm it doesn't need VT/SVM hardware. Unlike Xen it's simply "modprobe and go". Unlike both, it's 5000 lines and self-contained. Performance is ok, but not great (-30% on kernel compile). But given its hackability, I expect this to improve, along with the paravirt_ops code which it supplies a complete example for. There's also a 64-bit version being worked on and other craziness. But most of all, lguest is awesome fun! Too much of the kernel is a big ball of hair. lguest is simple enough to dive into and hack, plus has some warts which scream "fork me!". This patch: This is the code and headers required to make an i386 kernel an lguest guest.
