| * edac: rename channel_info to rank_infoMauro Carvalho Chehab2012-03-211-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | What it is pointed by a csrow/channel vector is a rank information, and not a channel information. On a traditional architecture, the memory controller directly access the memory ranks, via chip select rows. Different ranks at the same DIMM is selected via different chip select rows. So, typically, one csrow/channel pair means one different DIMM. On FB-DIMMs, there's a microcontroller chip at the DIMM, called Advanced Memory Buffer (AMB) that serves as the interface between the memory controller and the memory chips. The AMB selection is via the DIMM slot, and not via a csrow. It is up to the AMB to talk with the csrows of the DRAM chips. So, the FB-DIMM memory controllers see the DIMM slot, and not the DIMM rank. RAMBUS is similar. Newer memory controllers, like the ones found on Intel Sandy Bridge and Nehalem, even working with normal DDR3 DIMM's, don't use the usual channel A/channel B interleaving schema to provide 128 bits data access. Instead, they have more channels (3 or 4 channels), and they can use several interleaving schemas. Such memory controllers see the DIMMs directly on their registers, instead of the ranks, which is better for the driver, as its main usageis to point to a broken DIMM stick (the Field Repleceable Unit), and not to point to a broken DRAM chip. The drivers that support such such newer memory architecture models currently need to fake information and to abuse on EDAC structures, as the subsystem was conceived with the idea that the csrow would always be visible by the CPU. To make things a little worse, those drivers don't currently fake csrows/channels on a consistent way, as the concepts there don't apply to the memory controllers they're talking with. So, each driver author interpreted the concepts using a different logic. In order to fix it, let's rename the data structure that points into a DIMM rank to "rank_info", in order to be clearer about what's stored there. Latter patches will provide a better way to represent the memory hierarchy for the other types of memory controller. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| * i5400_edac: Avoid calling pci_put_device() twiceMauro Carvalho Chehab2012-03-211-16/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When i5400_edac driver is removed and re-loaded a few times, it causes an OOPS, as it is currently decrementing some PCI device usage two times. When called inside a loop, pci_get_device() will call pci_put_device(). That mangles the error count. In this specific case, it seems easier to just duplicate the call. Also fixes the error logic when pci_get_device fails. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If I only ack the detection register after a error have been detected I'm unable to reliably detect errors. I have verified this behavior using both an error injection DIMM and software to inject errors.

This allows us to significantly reduce the scope of headers including headers. For this instance, a reduction of about 40% is achieved by replacing the include with the simple fact that the device is some kind of a struct. Unlike the much larger module.h cleanup, this one is simply two commits. One to fix the implicit <linux/device.h> users, and then one to delete the device.h includes from the linux/include/ dir wherever possible." * tag 'device-for-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: device.h: audit and cleanup users in main include dir device.h: cleanup users outside of linux/include (C files)

This is counter-intuitive and awkward at the very least because, when setting the scrub rate, userspace has to write to sysfs and then read it back to check error status of the operation. As Tony notes, best it would be to not have the sdram_scrub_rate in sysfs if scrub rate support is not implemented. It is too late about that and a bunch of drivers on a bunch of arches would need to be changed and tested which is not a trivial task ATM. Instead, settle for the next best thing of returning -ENODEV when implementation is missing and -EINVAL when there was an error encountered while setting the scrub rate.

This happened because the module only performed a check for DRAM base ctl register0's and not DRAM base ctl register1's chip select enable bit. There could be systems with DIMMs populated on only single memory channel whereas the module also assumed that a dual channel dimm had double the memory size of a single memory channel instead of checking the memory on each channel.

* / asm-generic: architecture independent readq/writeq for 32bit environmentHitoshi Mitake2012-02-211-13/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides unified readq()/writeq() helper functions for 32-bit drivers. For some cases, readq/writeq without atomicity is harmful, and order of io access has to be specified explicitly. So in this patch, new two header files which contain non-atomic readq/writeq are added. - <asm-generic/io-64-nonatomic-lo-hi.h> provides non-atomic readq/ writeq with the order of lower address -> higher address - <asm-generic/io-64-nonatomic-hi-lo.h> provides non-atomic readq/ writeq with reversed order This allows us to remove some readq()s that were added drivers when the default non-atomic ones were removed in commit dbee8a0affd5 ("x86: remove 32-bit versions of readq()/writeq()") The drivers which need readq/writeq but can do with the non-atomic ones must add the line: #include <asm-generic/io-64-nonatomic-lo-hi.h> /* or hi-lo.h */ But this will be nop in 64-bit environments, and no other #ifdefs are required. So I believe that this patch can solve the problem of 1. driver-specific readq/writeq 2. atomicity and order of io access This patch is tested with building allyesconfig and allmodconfig as ARCH=x86 and ARCH=i386 on top of tip/master.

The microcode_core.c patch was provided by Stephen Rothwell <sfr@canb.auug.org.au> who was invaluable in the merge issues involved with the large sysdev removal process in the driver-core tree.

However, those fields still have some meaning for UP, and keeping them allows some #ifdef removal from other files. The additional size of the UP kernel from this change is not significant enough to worry about keeping up the distinction: text data bss dec hex filename 4737168 506459 972040 6215667 5ed7f3 vmlinux.o.before 4737444 506459 972040 6215943 5ed907 vmlinux.o.after for a difference of 276 bytes for an example UP config. If someone wants those 276 bytes back badly then it should be implemented in a cleaner way.

There's no broader range test yet to double check if the error decoding logic will actually point to the right DIMM, so use it with care. More tests are required to be sure that the driver will work on all different types of memory configurations. If you're willing to risk using it, I suggest you to enable EDAC debugs for your test machines, as the debug logs helps to track what's going inside the driver. Please feed me with bug reports, if you notice that the driver is miss-behaving. Tested-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
