This will be for setting per-card defaults. I'll use this as the baseline for vega56. Thanks for the request.

Hi @Enverex

Can you run the following for me and see what you get? I'm trying to see if there is a good way to detect the cards. Thanks! :)

SYSPATH=$(find /sys/devices -name pp_od_clk_voltage 2>/dev/null | sed 's|/pp_od_clk_voltage||g' |head -n1)
cat $SYSPATH/hwmon/hwmon0/device/class
cat $SYSPATH/hwmon/hwmon0/device/device
cat $SYSPATH/hwmon/hwmon0/device/vendor
cat $SYSPATH/hwmon/hwmon0/device/revision

[Enverex]

Sure.

[dasunsrule32]

@Enverex Ok, well, those all match my vega64 card, with the exception of the revision... Those won't work.

Can you try this and see what returns? Thanks for the help!
lspci -knn|grep VGA

[Enverex]

Probably exactly what you were expecting unfortunately...

03:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Vega 10 XL/XT [Radeon RX Vega 56/64] [1002:687f] (rev c3)

[dasunsrule32]

Yes, indeed... I'm going to have to figure out a differentiating way to distinguish the cards on Linux... I'm open to ideas lol

It's the same:

lspci -knn|grep VGA|grep -i amd|awk '{print $15}'
[1002:687f]

[Enverex]

I'm not sure anything of use is exposed to Linux to identify different brands to be honest. hwinfo says:

Nothing seems to be specific to this brand as opposed to Vega 56's in general.

[dasunsrule32]

Can you run the following and paste the output? Thanks again :)
lspci -v -s 03:00.0

I'm getting a line that might be specific to the card I have... I'm betting you return Vega 10 XL under Subsystem: :)

Looks like there is something this time...

[dasunsrule32]

This is giving a bit different info, I'm diffing ours to see if there is something viable to look at...

Out of curiosity, have you flashed the Vega64 bios on this card?

One more to run, if you can? lspci -knn and give me the output of 03:00.0. Should be about 4 lines.

[Enverex]

Nope, stock card/BIOS, etc. Notice in the previous output it did at least say "Subsystem: Sapphire Technology Limited Vega 10 XT [Radeon RX Vega 64]" so it was identified as a Sapphire branded card (where as yours just says AMD).

Here are the lines from lspci -knn:

03:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Vega 10 XL/XT [Radeon RX Vega 56/64] [1002:687f] (rev c3)
        Subsystem: Sapphire Technology Limited Vega 10 XT [Radeon RX Vega 64] [1da2:e376]
        Kernel driver in use: amdgpu
        Kernel modules: amdgpu
03:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Device [1002:aaf8]
        Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Device [1002:aaf8]
        Kernel driver in use: snd_hda_intel
        Kernel modules: snd_hda_intel

Conspiracy theory: Maybe the Sapphire 56 is actually a downclocked Vega 64? It's a smaller card than normal, but seems to have no issues overclocking while also undervolting like it has a LOT of headroom spare. Notice how small the card actually is:

[dasunsrule32]

I think we might have something... Look at the 03:00.0 under Subsystem:. Our identifiers are different, see below. I'm trying to get someone else with a vega56 to run that same command and post the results.

0d:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Vega 10 XL/XT [Radeon RX Vega 56/64] [1002:687f] (rev c1)
	Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Vega 10 XT [Radeon RX Vega 64] [1002:0b36]
	Kernel driver in use: amdgpu
	Kernel modules: amdgpu

Mine is [1002:0b36] and yours is [1da2:e376]. Looks like I might need to start a subsystem ID file and pull that in to an array, if this is the way to do it. Then maybe a case with the various default voltages.

It honestly wouldn't surprise me if it was, I mean they do that with Threadripper and Epyc. Disabling some of the cores/dies.

[dasunsrule32]

This horrible concoction seems to get that subsystem ID...

for s in $(lspci | grep VGA | awk '{print $1}'); do lspci -knn -v -s $s; done|grep Subsystem|grep AMD|awk '{print $14}'

This is a little simpler and seems to work as well:

lspci -v -knn | grep VGA -A 1|grep AMD|grep Subsystem|awk '{print $14}'

This gives some of the info as well, but might be easier to parse:

dmesg |grep -i vega
[    1.024722] [drm] initializing kernel modesetting (VEGA10 0x1002:0x687F 0x1002:0x0B36 0xC1).

Can you dump the results of this as well?
