Hi,

the text "Only works for DDR, DDR2, DDR3 and DDR4 for now" should be updated too.
With this fixed:

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").

Thanks,
Guenter

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.

I absolutely agree, hopefully by someone with such a system.

Testing this on top of 6.10-rc2+ on a Supermicro X13SAE, Linux logs:

     $ dmesg | grep -e "DMI:" -e "Linux version" -e i2c-0

Then with `sudo modprobe at24` and `sudo modprobe ee1004`, 
`decode-dimms` shows:

     $ sudo ./eeprom/decode-dimms

     Number of SDRAM DIMMs detected and decoded: 0

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


Kind regards and thank you again for these patches,

You'd actually have to load the spd5118 driver.

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

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:

I applied your patch

     $ git log --oneline --no-decorate -2
     00058a6 eeprom: Add basic spd5118 support
     a0e5865 i2cdetect: only use "newer" I2C_FUNC_* flags if they exist

but reading eeprom fails:

     $ sudo ./eeprom/decode-dimms
     Cannot read /sys/bus/i2c/drivers/spd5118/0-0050/eeprom at 
./eeprom/decode-dimms line 2465.


Kind regards,

Paul

decode-dimms does not need sudo, but that should not make a difference.

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

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f    0123456789abcdef
00: 51 18 0a 86 32 03 32 00 00 00 00 07 ff 7f 00 00    Q???2?2......?..
                                     ^^

and with

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f    0123456789abcdef
00: 51 18 0a 86 32 03 32 00 00 00 00 00 ff 7f 00 00    Q???2?2......?..
                                     ^^

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,
Guenter

Dear Guenter,


Thank you for your support.

Hopefully, I didn’t do something silly, that it does not work on my

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.

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 ?

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,
Guenter

I did

No, I did not.

It looks like it does:

     $ sudo sensors -s

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
/sys/class/hwmon/hwmon2/name:k10temp
/sys/class/hwmon/hwmon3/name:spd5118
/sys/class/hwmon/hwmon4/name:spd5118
/sys/class/hwmon/hwmon5/name:spd5118
/sys/class/hwmon/hwmon6/name:spd5118
/sys/class/hwmon/hwmon7/name:mt7921_phy0
/sys/class/hwmon/hwmon8/name:amdgpu

you could run

sudo bash -c 'echo 56000 > /sys/class/hwmon/hwmon3/temp1_max'

Please add

	.use_single_write = true,

to the regmap configuration (spd5118_regmap_config) to see if it helps.

Too bad. Still, thanks for trying!

I have a more comprehensive patch series which I think _should_ work.
I'll send it out for testing shortly.

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
