From a7d7d2e1a07e3811dc49af2962c940fd8bbb6c8f Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 27 Jan 2012 14:12:32 -0300 Subject: edac: Create a dimm struct and move the labels into it MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The way a DIMM is currently represented implies that they're linked into a per-csrow struct. However, some drivers don't see csrows, as they're ridden behind some chip like the AMB's on FBDIMM's, for example. This forced drivers to fake^Wvirtualize a csrow struct, and to create a mess under csrow/channel original's concept. Move the DIMM labels into a per-DIMM struct, and add there the real location of the socket, in terms of csrow/channel. Latter patches will modify the location to properly represent the memory architecture. All other drivers will use a per-csrow type of location. Some of those drivers will require a latter conversion, as they also fake the csrows internally. TODO: While this patch doesn't change the existing behavior, on csrows-based memory controllers, a csrow/channel pair points to a memory rank. There's a known bug at the EDAC core that allows having different labels for the same DIMM, if it has more than one rank. A latter patch is need to merge the several ranks for a DIMM into the same dimm_info struct, in order to avoid having different labels for the same DIMM. The edac_mc_alloc() will now contain a per-dimm initialization loop that will be changed by latter patches in order to match other types of memory architectures.

charset=UTF-8 Content-Transfer-Encoding: 8bit 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.

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.

Move it to the dimm struct. 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. A TODO fix here is to properly represent dual-rank/quad-rank DIMMs when the memory controller represents the memory via chip select rows.

There are lots of those memory controllers nowadays, and more are coming. So, the EDAC internal representation needs to be changed, in order to work with those memory controllers, while preserving backward compatibility with the old ones. The edac core was written with the idea that memory controllers are able to directly access csrows. This is not true for FB-DIMM and RAMBUS memory controllers. Also, some recent advanced memory controllers don't present a per-csrows view. Instead, they view memories as DIMMs, instead of ranks. So, change the allocation and error report routines to allow them to work with all types of architectures. This will allow the removal of several hacks with FB-DIMM and RAMBUS memory controllers. Also, several tests were done on different platforms using different x86 drivers. TODO: a multi-rank DIMMs are currently represented by multiple DIMM entries in struct dimm_info. That means that changing a label for one rank won't change the same label for the other ranks at the same DIMM. This bug is present since the beginning of the EDAC, so it is not a big deal. However, on several drivers, it is possible to fix this issue, but it should be a per-driver fix, as the csrow => DIMM arrangement may not be equal for all. So, don't try to fix it here yet. I tried to make this patch as short as possible, preceding it with several other patches that simplified the logic here. Yet, as the internal API changes, all drivers need changes. The changes are generally bigger in the drivers for FB-DIMMs. Cc: Aristeu Rozanski Cc: Doug Thompson Cc: Borislav Petkov Cc: Mark Gross Cc: Jason Uhlenkott Cc: Tim Small Cc: Ranganathan Desikan Cc: "Arvind R."

This could eventually match what is described at the dmidecode, making easier for people to identify the memory. For example, on an Intel motherboard where the DMI table is reliable, the first memory stick is described as: Memory Device Array Handle: 0x0029 Error Information Handle: Not Provided Total Width: 64 bits Data Width: 64 bits Size: 2048 MB Form Factor: DIMM Set: 1 Locator: A1_DIMM0 Bank Locator: A1_Node0_Channel0_Dimm0 Type: Type Detail: Synchronous Speed: 800 MHz Manufacturer: A1_Manufacturer0 Serial Number: A1_SerNum0 Asset Tag: A1_AssetTagNum0 Part Number: A1_PartNum0 The memory named as "A1_DIMM0" is physically located at the first memory controller (node 0), at channel 0, dimm slot 0. After this patch, the memory label will be filled with: /sys/devices/system/edac/mc/csrow0/ch0_dimm_label:mc#0channel#0slot#0 And (after the new EDAC API patches) as: /sys/devices/system/edac/mc/mc0/dimm0/dimm_label:mc#0channel#0slot#0 So, even if the memory label is not initialized on userspace, an useful information with the error location is filled there, expecially since several systems/motherboards are provided with enough info to map from channel/slot (or branch/channel/slot) into the DIMM label. So, letting the EDAC core fill it by default is a good thing. It should noticed that, as the label filling happens at the edac_mc_alloc(), drivers can override it to better describe the memories (and some actually do it).

Only one of the csrows will contain the entire DIMM size. If single rank memories are found, they'll be marked with 0 bytes. The check if the AMB is present were also wrong. Yet, as the error reports don't use the memory size in order to credit an error to the right DIMM, that part of the driver seems to work. That's why probably nobody detected the issue yet.
