* EDAC, ppc4xx_edac: Fix module autoload for OF platform driverLuis de Bethencourt2015-10-031-0/+1
| | | | | | | | | | | | This platform driver has an OF device ID table but the OF module alias information is not created so module autoloading won't work.

* edac: edac_mc_handle_error(): add an error_count parameterMauro Carvalho Chehab2012-06-121-2/+2
| | | | | | | | | | | | | | | | | In order to avoid loosing error events, it is desirable to group error events together and generate a single trace for several identical errors. The trace API already allows reporting multiple errors. Change the handle_error function to also allow that. The changes at the drivers were made by this small script: $file .=$_ while (<>); $file =~ s/(edac_mc_handle_error)\s*\(([^\,]+)\,([^\,]+)\,/$1($2,$3, 1,/g; print $file; Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* edac: remove arch-specific parameter for the error handlerMauro Carvalho Chehab2012-06-111-2/+2

It probably doesn't make sense to have an MCE-specific tracepoint, as this will cost more bytes at the tracepoint, and tracepoint is not free. The changes at the EDAC drivers were done by this small perl script: $file .=$_ while (<>); $file =~ s/(edac_mc_handle_error)\s*\(([^\;]+)\,([^\,\)]+)\s*\)/$1($2)/g; print $file; Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

After this change, it is possible to add sysfs nodes for the DIMM's that will properly represent the DIMM stick properties, including its size.

* edac: Don't initialize csrow's first_page & friends when not neededMauro Carvalho Chehab2012-05-281-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Almost all edac drivers initialize csrow_info->first_page, csrow_info->last_page and csrow_info->page_mask. Those vars are used inside the EDAC core, in order to calculate the csrow affected by an error, by using the routine edac_mc_find_csrow_by_page(). However, very few drivers actually use it: e752x_edac.c e7xxx_edac.c i3000_edac.c i82443bxgx_edac.c i82860_edac.c i82875p_edac.c i82975x_edac.c r82600_edac.c There also a few other drivers that have their own calculus formula internally using those vars. All the others are just wasting time by initializing those data. While initializing data without using them won't cause any troubles, as those information is stored at the wrong place (at csrows structure), it is better to remove what is unused, in order to simplify the next patch.

* edac: move dimm properties to struct dimm_infoMauro Carvalho Chehab2012-05-281-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On systems based on chip select rows, all channels need to use memories with the same properties, otherwise the memories on channels A and B won't be recognized. However, such assumption is not true for all types of memory controllers. Controllers for FB-DIMM's don't have such requirements. Also, modern Intel controllers seem to be capable of handling such differences. So, we need to get rid of storing the DIMM information into a per-csrow data, storing it, instead at the right place. The first step is to move grain, mtype, dtype and edac_mode to the per-dimm struct.

* | drivercore: revert addition of of_match to struct deviceGrant Likely2011-05-181-1/+1
|/ | | | | | | | | | | | | | | Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

* edac: new ppc4xx driver moduleGrant Erickson2009-04-021-0/+1448
This adds support for an EDAC memory controller adaptation driver for the "ibm,sdram-4xx-ddr2" ECC controller realized in the AMCC PowerPC 405EX[r]. At present, this driver has been developed and tested against the controller realization in the AMCC PPC405EX[r] on the AMCC Kilauea and Haleakala boards (256 MiB w/o ECC memory soldered onto the board) and a proprietary board based on those designs (128 MiB ECC memory, also soldered onto the board). In the future, dynamic feature detection and handling needs to be added for the other realizations of this controller found in the 440SP, 440SPe, 460EX, 460GT and 460SX. Eventually, this driver will likely be evolved and adapted to the above variant realizations of this controller as well as broken apart to handle the other known ECC-capable controllers prevalent in other PPC4xx processors: - IBM SDRAM (405GP, 405CR and 405EP) "ibm,sdram-4xx" - IBM DDR1 (440GP, 440GX, 440EP and 440GR) "ibm,sdram-4xx-ddr" - Denali DDR1/DDR2 (440EPX and 440GRX) "denali,sdram-4xx-ddr2" [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Grant Erickson <gerickson@nuovations.com> Signed-off-by: Doug Thompson <dougthompson@xmission.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
