ZenBleed microcode update for Amd  EPYC gen2

microcode-0.20230613-2.mga8.nonfree.noarch.rpm

Comment 1 Dave Hodgins 2023-07-25 21:26:20 CEST

No regressions noticed in either of my x8t_64 systms, aarch64 rpi 4b, i586 and
vb guests.

In the x86_64 laptop cpuinfo has ...
cpu family      : 23
model           : 96
model name      : AMD Ryzen 7 4800H with Radeon Graphics

Running the zenbleed poc shows
Spawning 8 Threads...
zenbleed: failed to start thread on specifed code 1: Success

before and after the kernel or microcode update.

Comment 2 Martin Whitaker 2023-07-25 22:25:10 CEST

cpu family	: 23
model		: 104
model name	: AMD Ryzen 5 5500U with Radeon Graphics

Installs cleanly, but does not contain fixes for this CPU. The journal still reports

  kernel: Zenbleed: please update your microcode for the most optimal fix

No regressions noticed so far.

Comment 3 Len Lawrence 2023-07-26 00:04:01 CEST

Mageia8, x86_64
AMD Ryzen 7 5700U  16 cores
Installs OK.
The journal after reboot issues same notices as in comment 2 and
reports patch_level=0x08608102 for each CPU core.

Too early for conclusion on regressions.  None noted anyway.

Comment 4 Thomas Andrews 2023-07-26 14:31:20 CEST

MGA8-64 Plasma system, A8-4555M APU. Predates any kind of Zen, so is probably unaffected by this issue. Updated this and the kernel in one operation, no issues noted so far.

Comment 5 Len Lawrence 2023-07-26 19:22:36 CEST

Kernel: 5.15.117-desktop-2.mga8 x86_64
10-Core Intel Core i9-7900X
NVIDIA GP102 [GeForce GTX 1080 Ti]

After reboot the journal showed this:

Jul 26 17:58:49 canopus [RPM][209023]: erase microcode-0.20230512-1.mga8.nonfree.noarch: success
Jul 26 17:58:49 canopus [RPM][209023]: install microcode-0.20230613-2.mga8.nonfree.noarch: success
Jul 26 18:01:15 canopus kernel: microcode: microcode updated early to revision 0x2006f05, date = 2022-12-21
Jul 26 18:01:15 canopus kernel: microcode: sig=0x50654, pf=0x4, revision=0x2006f05

Expected outcome probably with this hardware.

Desktop still working normally.
