+Description
+-----------
+
+This driver implements support for SPD5118 (JEDEC JESD300) compliant temperature
+sensors, which are used on many DDR5 memory modules. Some systems use the sensor
+to prevent memory overheating by automatically throttling the memory controller.
+
+The driver auto-detects SPD5118 compliant chips, but can also be instantiated
+using devicetree/firmware nodes.
+
+A SPD5118 compliant chip supports a single temperature sensor. Critical minimum,
+minimum, maximum, and critical temperature can be configured. There are alarms
+for low critical, low, high, and critical thresholds.
+
+
+Hardware monitoring sysfs entries
+---------------------------------
+
+======================= ==================================
+temp1_input		Temperature (RO)
+temp1_lcrit		Low critical high temperature (RW)
+temp1_min		Minimum temperature (RW)
+temp1_max		Maximum temperature (RW)
+temp1_crit		Critical high temperature (RW)
+
+temp1_lcrit_alarm	Temperature low critical alarm
+temp1_min_alarm		Temperature low alarm
+temp1_max_alarm		Temperature high alarm
+temp1_crit_alarm	Temperature critical alarm
+======================= ==================================
+
+Alarm attributes are sticky until read and will be cleared afterwards
+unless the alarm condition still applies.

PATCH v4 4/6 hwmon: (spd5118) Add support for reading SPD data

Add support for reading SPD NVMEM data from SPD5118 (Jedec JESD300) compliant memory modules. NVMEM write operation is not supported.

NVMEM support is optional. If CONFIG_NVMEM is disabled, the driver will still instantiate but not provide NVMEM attribute files.

Ignore nvmem registration failure if nvmem support is disabled

Hi,

do we really need this setting here?

The "eeprom" file is only created if both "base_dev" and "compat" are set. decode-dimms depends on it. While decode-dimms has to be updated anyway, I did not want to make that more complicated than necessary.

Another option would be not to use the nvmem subsystem in the first place, similar to the ee1004 driver, but my understanding is that the use of the nvmem subsystem is preferred.

We could, but I prefer to avoid conditionals in the code if possible, the dummy devm_nvmem_register() is there specifically to cover that situation, and no other driver does that. Also, since the underlying functions are dummy, the compiler should optimize it all away if CONFIG_NVMEM=n.

Correct. The hack below makes it detect the DIMMs, but the data format is all different, so it is only really useful to validate reading the EEPROM (i.e., the checksum over the first 512 bytes of the eeprom is correct). With that patch applied, I get

Then with sudo modprobe at24 and sudo modprobe ee1004, decode-dimms shows:
You'd actually have to load the spd5118 driver.

Indeed. I didn’t check with the last version, but using your patch set v5 [1] on top of Linux 6.10-rc4, it was loaded:

This might be expected, and decode-dimms also needs to be updated.

Correct. The hack below makes it detect the DIMMs, but the data format is all different, so it is only really useful to validate reading the EEPROM (i.e., the checksum over the first 512 bytes of the eeprom is correct). With that patch applied, I get

Well, it _is_ a hack ;-), but that specific operation should not fail.

Please try the following:

ls -l /sys/bus/i2c/drivers/spd5118/0-0050/eeprom cp /sys/bus/i2c/drivers/spd5118/0-0050/eeprom /tmp od -t x1 /sys/bus/i2c/drivers/spd5118/0-0050/eeprom sudo i2cdump -y -f 0 0x50

All those should work, and the size of /tmp/eeprom should be 1024 bytes. The output of i2cdump should start with something like

after executing the "sensors" command.

Other than that, I can see that your system is an Intel system, meaning the i2c controller would be i801, not piix4. I wonder if that makes a difference. Has anyone else seeing this tested eeprom access with i801 (or any other controller besides piix4), by any chance ?

Thanks,

Hopefully, I didn’t do something silly, that it does not work on my system yet. sensors is able to read stuff:

Sorry, I only have Intel systems with DDR5 RAM at disposal.

That suggests that the i801 driver got an error when trying some chip operation. Unfortunately I have no idea what that error or the failed operation might be.

This should work after you load the "i2c-dev" module.

If you get it to work, please provide the output. Maybe it helps tracking down the problem.

Yes, that assumed that reading the nvram/eeprom succeeded, which it didn't. The value might also be 7 directly after booting and before loading the spd5118 driver.

Anyway, it almost looks like setting the page doesn't work, or maybe write operations in general.

Can you try the following ?

dd if=/sys/bus/i2c/drivers/spd5118/0-0050/eeprom of=/tmp/eeprom count=64 bs=1

and

dd if=/sys/bus/i2c/drivers/spd5118/0-0050/eeprom of=/tmp/eeprom count=1 bs=64

That should only try to read from page 0.

Also, please try to set a temperature limit, either temp1_max or temp1_crit. Setting temp1_max to, say, 56000, or temp1_crit to 84000 should do.

Thanks,

You'd have to write directly into the attribute files. For example, if you have

$ grep . /sys/class/hwmon/*/name
/sys/class/hwmon/hwmon0/name:nvme
/sys/class/hwmon/hwmon1/name:nct6687

you could run

So, as I suspected, that means that all write operations fail, meaning the write operation used by regmap is not supported by the chip and/or by the i2c controller.

That makes me wonder if the same problem is seen with other variants of the same problem. If so, we may have to drop regmap support completely.

Does anyone else of those listening in have a Intel/i801 system and could possibly test if they have the same problem ?

Thanks,
Guenter

So (00,b) = 0x00 opposed to 0x07 in your example output.
Yes, that assumed that reading the nvram/eeprom succeeded, which it didn't. The value might also be 7 directly after booting and before loading the spd5118 driver.
Anyway, it almost looks like setting the page doesn't work, or maybe write operations in general.
Can you try the following ?

Also, please try to set a temperature limit, either temp1_max or temp1_crit. Setting temp1_max to, say, 56000, or temp1_crit to 84000 should do.
I did

Did you run "sudo sensors -s" ?

I don't know if that would report errors, though.

That suggests that the i801 driver got an error when trying some chip operation. Unfortunately I have no idea what that error or the failed operation might be.

So (00,b) = 0x00 opposed to 0x07 in your example output.
Yes, that assumed that reading the nvram/eeprom succeeded, which it didn't. The value might also be 7 directly after booting and before loading the spd5118 driver.
Anyway, it almost looks like setting the page doesn't work, or maybe write operations in general.

I rephrased it to "Only works for (LP)DDR memory types up to DDR5".

How about "Only works on systems with 1 to 8 memory slots" ? That isn't really correct anymore either, unless I misunderstand the changes made in commit 8821c8376993 ("i2c: smbus: Prepare i2c_register_spd for usage on muxed segments").

This is a question for Heiner. I'd think it is is still correct, but I don't know exactly.

My interpretation was that it should work if the DIMMs are connected to multiplexed I2C busses, but probably not if they are connected to different adapters. The error message in that case is a bit misleading, though, because it claims that "More than 8 memory slots on a single bus", which isn't necessarily the case. For example, it should be perfectly valid to have up to 24 DIMMs in this system.

i2c-0/name:SMBus PIIX4 adapter port 0 at 0b00
i2c-1/name:SMBus PIIX4 adapter port 2 at 0b00
i2c-2/name:SMBus PIIX4 adapter port 1 at 0b20

... but I guess that is a question for someone with such a system to answer.

Ultimately the handling of systems with more than 8 memory slots will need to be updated at some point. On my systems, with 'i2c: piix4: Register SPDs' applied, I see

i2c i2c-0: 4/4 memory slots populated (from DMI)
[my system is running 6.6.y which still generates that message]
i2c i2c-0: Successfully instantiated SPD at 0x50
i2c i2c-0: Successfully instantiated SPD at 0x51
i2c i2c-0: Successfully instantiated SPD at 0x52
i2c i2c-0: Successfully instantiated SPD at 0x53
i2c i2c-1: 4/4 memory slots populated (from DMI)
i2c i2c-2: 4/4 memory slots populated (from DMI)

meaning the function is called for each adapter (which makes sense). However, the code counting the DIMMs doesn't really take the adapter into account, meaning adapters 1 and 2 are still probed even though all DIMMs were already instantiated from adapter 0.

On a system with more than 8 DIMMs connected to different piix4 adapters (without mux) we'd probably see something like

i2c i2c-0: More than 8 memory slots on a single bus, contact i801 maintainer ... i2c i2c-1: More than 8 memory slots on a single bus, contact i801 maintainer ... i2c i2c-2: More than 8 memory slots on a single bus, contact i801 maintainer ...

which wouldn't be very helpful. I think the main problem may be that the i801 driver implements sub-adapters as muxes, but the piix4 driver doesn't do (or need) that. The message is also i801 centric which doesn't apply anymore after 'i2c: piix4: Register SPDs' is applied.

However, I would not want to even try changing that code without access to a system using piix4 and supporting more than 8 memory slots.

Thanks,
Guenter

It seems Intel systems never have more than one i801 SMBUS adapter, therefore systems with more than 8 memory slots have to use muxing. The current code was developed for the Intel use case, and therefore doesn't consider that a system may have dedicated SMBUS controllers per 8 memory slots. So support for this scenario has to be added.

PATCH v4 6/6 hwmon: (spd5118) Add configuration option for auto-detection

With SPD5118 chip detection for the most part handled by the i2c-smbus core using DMI information, the spd5118 driver no longer needs to auto-detect spd5118 compliant chips.

Auto-detection by the driver is still needed on systems with no DMI support or on systems with more than eight DIMMs and can not be removed entirely. However, it affects boot time and introduces the risk of mis-identifying chips. Add configuration option to be able to disable it on systems where chip detection is handled outside the driver.

The combination of

looks weird.

Also right now it is not possible to disable detection on non-DMI configurations. But when using OF, custom kernel code or userspace instantiation then neither DMI nor CONFIG_DETECT are necessary.

The following would support those usecases, too:

config SENSORS_SPD5118_DETECT

I don't think "default !DMI" would be a good idea because DMI is supported by multiple architectures, but only two X86 specific controllers call i2c_register_spd().

"default !DMI || !X86" might work, though. I think I'll use that.

I'll rephrase the text and drop the "select".

That would be nice, but i2c_register_spd() is only called from i2c-i801.c and, with the recent patch, from i2c-piix4.c. DMI is also supported on arm, arm64, loongarch, and mips. i2c_register_spd() will not be called on those systems or, more generally, if the adapter used to connect to the DIMMs is not one of those two.

On top of that, it may be desirable to disable it for a system with DMI support if that system boots from devicetree. I don't know if such a system exists, but I would not want to bet that it doesn't.
