* edac: e752x fix too loud on nonmemory errorsDoug Thompson2008-07-251-17/+42
| | | | | | | | | | | | | | | | 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 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>
* edac: fix module initialization on several modules 2nd timeHitoshi Mitake2008-04-291-10/+5
| | | | | | | | | | | | | | | | | | | | | I implemented opstate_init() as a inline function in linux/edac.h. added calling opstate_init() to: i82443bxgx_edac.c i82860_edac.c i82875p_edac.c i82975x_edac.c I wrote a fixed patch of edac-fix-module-initialization-on-several-modules.patch, and tested building 2.6.25-rc7 with applying this. It was succeed. I think the patch is now correct.

* edac: add e752x parameter for sysbus_parity selectionPeter Tyser2008-04-291-1/+39
| | | | | | | | | | | | | | | | | | | | | Add a module parameter "sysbus_parity" to allow forcing system bus parity error checking on or off. Also add support to automatically disable system bus parity errors for processors which do not support it. If the sysbus_parity parameter is specified, sysbus parity detection will be forced on or off. If it is not specified, the driver will attempt to look at the CPU identifier string and determine if the CPU supports system bus parity. A blacklist was used instead of a whitelist so that system bus parity would be enabled by default and to minimize the chances of breaking things for those people already using the driver which for some reason have a processor that does not have a valid CPU identifier string.

| | | | | | | | | | | | | | | | Refactoring of sysfs code necessitated the refactoring of the edac_mc_alloc() and edac_mc_add_mc() 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.

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!

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.

| | | | | | | | | | | | | | | Address the issue of EDAC/BIOS coexistence for the e752x chip-sets. We have found a problem where the BIOS will start the system with the error registers (dev0:fun1) hidden and assuming it has exclusive access to them. The edac driver violates this assumption. The workaround this patch offers is to honor the hidden-ness as an indication that it is not safe to use those registers.

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.
