AGESA 1.2.0A for AM4 released

anon49550872 · August 4, 2023, 12:53pm

New BIOS released today ? What a surprise…

ricklinux · August 4, 2023, 4:01pm

I’ve had the AGESA 1.2.0A since May on the MSI X570 board.

anon49550872 · August 4, 2023, 4:24pm

Nice, I’m already testing it, same BIOS settings as before, I can’t feel any difference.
What I read about is that this new BIOS helps to save power for NVME devices with a new CPPC option but I couldn’t find anything new in BIOS to change..

mbod · August 4, 2023, 4:33pm

I am a little bit confused about the version numbers.

I have a Gigabyte X570 AORUS ULTRA board. Latest BIOS version F36 has AMD AGESA V2 1.2.0.7. And that was relased Dec. 2022. The next beta BIOS F37B has AMD AGESA V2 1.2.0.8.

How does that compare to the version number you are seeing: 1.2.0A ?

PS
I am answering my own question 1.2.0A is the newest version and it comes after 1.2.0.8

1.2.0C is coming late this year:

This is what i have on my MPG X570 Gaming Plus

swh · August 5, 2023, 11:03am

For my AOURUS B550 I did a BIOS update today. The F16e uses AMD AGESA V2 1.2.0.8
No idea when the 1.2.0A should be released

anon49550872 · August 5, 2023, 3:44pm

I found the option…

In my PC, this new option is located at: Advanced / Onboard devices configuration.

It was originally set to Auto.

$ sudo lspci -vv | grep 'ASPM.*abled;'

		LnkCtl:	ASPM Disabled; RCB 64 bytes, Disabled- CommClk+
		LnkCtl:	ASPM Disabled; RCB 64 bytes, Disabled- CommClk+

Once I changed it from Auto to L0s And L1 Entry in BIOS:

$ sudo lspci -vv | grep 'ASPM.*abled;'

		LnkCtl:	ASPM L1 Enabled; RCB 64 bytes, Disabled- CommClk+
		LnkCtl:	ASPM L1 Enabled; RCB 64 bytes, Disabled- CommClk+

		LnkCtl:	ASPM L1 Enabled; Disabled- CommClk+

		LnkCtl:	ASPM Disabled; RCB 64 bytes, Disabled- CommClk+
		LnkCtl:	ASPM Disabled; RCB 64 bytes, Disabled- CommClk+

What I’m now trying to understand is the difference between these modes, and what default mode means:

$ cat /sys/module/pcie_aspm/parameters/policy
[default] performance powersave powersupersave

lspci-vvv below showing that my NVME drives only support L1 power state.

sudo lspci -vvv

01:00.0 Non-Volatile memory controller: Sandisk Corp WD PC SN810 / Black SN850 NVMe SSD (rev 01) (prog-if 02 [NVM Express])

nvme1 has the same output of nvme0 get-feature, so I’ll omit it.

sudo nvme get-feature /dev/nvme0 -f 0x0c -H

$ sudo dmesg | grep ASPM

[    0.451245] acpi PNP0A08:00: _OSC: OS supports [ExtendedConfig ASPM ClockPM Segments MSI EDR HPX-Type3]

Edit:
Added to my kernel cmdline pcie_aspm.policy=powersupersave and now I have:

$ cat /sys/module/pcie_aspm/parameters/policy
default performance powersave [powersupersave]

Edit2:
According to redhat’s wiki:

But they don’t mention the powersupersave option…

On my MSI board i have same CPU PCIE ASPM Mode Control

Disabled
L0s Entry
L1 Entry
L0s And L1 Entry
Auto

Mine is set to Auto.

ricklinux · August 5, 2023, 5:33pm

Did you have to change the setting in the ASPM control also?

anon49550872 · August 5, 2023, 5:35pm

Just changed in the BIOS from Auto to L0s And L1 Entry.
This will enable it into default settings.
According to redhat’s wiki, default settings will let the firmware decide everything:

default
sets PCIe link power states according to the defaults specified by the firmware on the system (for example, BIOS). This is the default state for ASPM.
powersave
sets ASPM to save power wherever possible, regardless of the cost to performance.
performance
disables ASPM to allow PCIe links to operate with maximum performance.

Unfortunately I didn’t find anything about powersupersave option yet..

I changed my kernel cmdline to use powersupersave and I’m currently testing it, everything is working fine here so far with this mode.

ricklinux · August 5, 2023, 5:39pm

Okay i just tried it and i have the same.

[ricklinux@eos-kde ~]$ cat /sys/module/pcie_aspm/parameters/policy
default performance powersave [powersupersave]

anon49550872 · August 5, 2023, 5:42pm

Nice, so we will both be testing it, if you notice something weird let me know and vice versa.
Always good to save power, and according to what I have been reading, the performance impact shouldn’t be noticeable…

Although, I read some comments that some NICs (Network card interfaces), may get some latency when “waking up” and weird behaviors. But this is specific to some chips only.

ricklinux · August 5, 2023, 5:44pm

What package did you install for the command

sudo nvme get-feature /dev/nvme0 -f 0x0c -H

anon49550872 · August 5, 2023, 5:45pm

#pacman -S nvme-cli

Or, the git version from AUR.

ricklinux · August 5, 2023, 5:47pm

I think i had this installed once before but i accidentally wiped my system out and had to reinstall when testing. Oops!

anon49550872 · August 5, 2023, 5:47pm

Who never?

ricklinux · August 5, 2023, 5:49pm

The command isn’t working. My drive is:

You should omit n1p* part from it, these are the partitions.
So, the command should be exactly as it is in my previous post:

use sudo:

nvme get-feature /dev/nvme0 -f 0x0c -H

ricklinux · August 5, 2023, 5:53pm

How do you post it that way with the drop down arrow?
