The 'test_device_edac' sample driver is located at the
bluesmoke.sourceforge.net project site for EDAC.
=======================================================================
NEHALEM USAGE OF EDAC APIs
This chapter documents some EXPERIMENTAL mappings for EDAC API to handle
Nehalem EDAC driver. They will likely be changed on future versions
of the driver.
Due to the way Nehalem exports Memory Controller data, some adjustments
were done at i7core_edac driver. This chapter will cover those differences
1) On Nehalem, there are one Memory Controller per Quick Patch Interconnect
(QPI). At the driver, the term "socket" means one QPI. This is
associated with a physical CPU socket.
Each MC have 3 physical read channels, 3 physical write channels and
3 logic channels. The driver currenty sees it as just 3 channels.
Each channel can have up to 3 DIMMs.
The minimum known unity is DIMMs. There are no information about csrows.
As EDAC API maps the minimum unity is csrows, the driver sequencially
maps channel/dimm into different csrows.
For example, suposing the following layout:
Ch0 phy rd0, wr0 (0x063f4031): 2 ranks, UDIMMs
dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
dimm 1 1024 Mb offset: 4, bank: 8, rank: 1, row: 0x4000, col: 0x400
Ch1 phy rd1, wr1 (0x063f4031): 2 ranks, UDIMMs
dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
Ch2 phy rd3, wr3 (0x063f4031): 2 ranks, UDIMMs
dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
The driver will map it as:
csrow0: channel 0, dimm0
csrow1: channel 0, dimm1
csrow2: channel 1, dimm0
csrow3: channel 2, dimm0
exports one
DIMM per csrow.
Each QPI is exported as a different memory controller.
2) Nehalem MC has the hability to generate errors. The driver implements this
functionality via some error injection nodes:
For injecting a memory error, there are some sysfs nodes, under
/sys/devices/system/edac/mc/mc?/:
inject_addrmatch/*:
Controls the error injection mask register. It is possible to specify
several characteristics of the address to match an error code:
dimm = the affected dimm. Numbers are relative to a channel;
rank = the memory rank;
channel = the channel that will generate an error;
bank = the affected bank;
page = the page address;
column (or col) = the address column.
each of the above values can be set to "any" to match any valid value.
At driver init, all values are set to any.
For example, to generate an error at rank 1 of dimm 2, for any channel,
any bank, any page, any column:
echo 2 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/dimm
echo 1 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/rank
To return to the default behaviour of matching any, you can do:
echo any >/sys/devices/system/edac/mc/mc0/inject_addrmatch/dimm
echo any >/sys/devices/system/edac/mc/mc0/inject_addrmatch/rank
inject_eccmask:
specifies what bits will have troubles,
inject_section:
specifies what ECC cache section will get the error:
3 for both
2 for the highest
1 for the lowest
inject_type:
specifies the type of error, being a combination of the following bits:
bit 0 - repeat
bit 1 - ecc
bit 2 - parity
inject_enable starts the error generation when something different
than 0 is written.
All inject vars can be read. root permission is needed for write.
Datasheet states that the error will only be generated after a write on an
address that matches inject_addrmatch. It seems, however, that reading will
also produce an error.
For example, the following code will generate an error for any write access
at socket 0, on any DIMM/address on channel 2:
echo 2 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/channel
echo 2 >/sys/devices/system/edac/mc/mc0/inject_type
echo 64 >/sys/devices/system/edac/mc/mc0/inject_eccmask
echo 3 >/sys/devices/system/edac/mc/mc0/inject_section
echo 1 >/sys/devices/system/edac/mc/mc0/inject_enable
dd if=/dev/mem of=/dev/null seek=16k bs=4k count=1 >& /dev/null
For socket 1, it is needed to replace "mc0" by "mc1" at the above
commands.
The generated error message will look like:
EDAC MC0: UE row 0, channel-a= 0 channel-b= 0 labels "-": NON_FATAL (addr = 0x0075b980, socket=0, Dimm=0, Channel=2, syndrome=0x00000040, count=1, Err=8c0000400001009f:4000080482 (read error: read ECC error))
3) Nehalem specific Corrected Error memory counters
Nehalem have some registers to count memory errors. The driver uses those
registers to report Corrected Errors on devices with Registered Dimms.
However, those counters don't work with Unregistered Dimms. As the chipset
offers some counters that also work with UDIMMS (but with a worse level of
granularity than the default ones), the driver exposes those registers for
UDIMM memories.
They can be read by looking at the contents of all_channel_counts/
$ for i in /sys/devices/system/edac/mc/mc0/all_channel_counts/*; do echo $i; cat $i; done
/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm0
0
/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm1
0
/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm2
0
What happens here is that errors on different csrows, but at the same
dimm number will increment the same counter.
So, in this memory mapping:
csrow0: channel 0, dimm0
csrow1: channel 0, dimm1
csrow2: channel 1, dimm0
csrow3: channel 2, dimm0
The hardware will increment udimm0 for an error at the first dimm at either
csrow0, csrow2 or csrow3;
The hardware will increment udimm1 for an error at the second dimm at either
csrow0, csrow2 or csrow3;
The hardware will increment udimm2 for an error at the third dimm at either
csrow0, csrow2 or csrow3;
4) Standard error counters
The standard error counters are generated when an mcelog error is received
by the driver. Since, with udimm, this is counted by software, it is
possible that some errors could be lost. With rdimm's, they displays the
contents of the registers
