|
||||

=======================================================================
|
||||
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

The I2C protocol knows about two kinds of device addresses: normal 7 bit

addresses, and an extended set of 10 bit addresses. The sets of addresses

address 0x10 (though a single device could respond to both of them). You
