Drivers & Software

I can find no firmware for my processor Ryzen 5 5500U, this is my CPU and firmware version:

vendor_id : AuthenticAMD
cpu family : 23
model : 104
model name : AMD Ryzen 5 5500U with Radeon Graphics
stepping : 1
microcode : 0x8608102

More details:

vendor_id = "AuthenticAMD"
version information (1/eax):
processor type = primary processor (0)
family = 0xf (15)
model = 0x8 (8)
stepping id = 0x1 (1)
extended family = 0x8 (8)
extended model = 0x6 (6)
(family synth) = 0x17 (23)
(model synth) = 0x68 (104)

I can not find any updated version (https://github.com/platomav/CPUMicrocodes/tree/master/AMD). My version is affected by Zenbleed:

[ 0.076593] Zenbleed: please update your microcode for the most optimal fix

I've tried this using Windows 10 on a USB stick, it fails complaining about the OS using this SW: https://www.amd.com/en/support/cpu/amd-ryzen-processors/amd-ryzen-5-desktop-processors/amd-ryzen-5-5...

So there is a firmware for Windows, but no way to install it on a Linux server.

Any ideas?

Thanks,

Jordi

Check the laptop makers website for a bios update.

None of the software you're trying to install has anything to do with it.

I have already applied latest version of BIOS from the laptop maker, no changes. I have contacted them for a solution.

An updated firmware for Zenbleed, initially announced for December, is targeted for January... although it's February already...

I have installed a second HD on my PC. I've installed Windows 11 and updated everything. When I go back to my Linux on the first disk, everything remains de same.
