I'm not sure what's going wrong here, I'm on a clean master tree
but your first patch does not apply:

Hi.
I did wrongly spell myself out instead of "This series needs to be
applied on top of 'intel-microcode: load as early as possible'
series." it should be: "This series needs to be applied after
'intel-microcode: load as early as possible' series.". Sorry about
it.
Nope - turns out I was too quick, my apologies :-(. I merely looked
at your first mail that actually had a patch for AMD and not at the
one preceding it (which stated I needed to apply the Intel series
first). Applied cleanly. How do I check whether it's functional? I
grepped dmesg for AMD or ucode, but nothing shows. Logread doesn't
work at all (but I reckon that's unrelated).
You should grep -i for "microcode", it should say something like:
"microcode updated early ..." probably on first line in kernel log.
Strange thing is that logread doesn't work, but I don't know what's
causing this.
Hi Thomas,
I just booted OpenWrt off my USB stick, grepping for microcode returned
this:
[ 2.038790] microcode: CPU0: patch_level=0x08001129
[ 2.043782] microcode: CPU1: patch_level=0x08001129
[ 2.114395] microcode: CPU2: patch_level=0x08001129
[ 2.119391] microcode: CPU3: patch_level=0x08001129
[ 2.124390] microcode: CPU4: patch_level=0x08001129
[ 2.129382] microcode: CPU5: patch_level=0x08001129
[ 2.134512] microcode: CPU6: patch_level=0x08001129
[ 2.139498] microcode: CPU7: patch_level=0x08001129
[ 2.144491] microcode: Microcode Update Driver: v2.2.
Does that help you any? Tested on a Ryzen 1800X.
I reckon logread not working might have to do with my using the
combined-ext4 image, /tmp is kinda broken as well.
Cheers
Stijn
Dmesg does say full retpoline support has been enabled, but unless
I'm mistaken that was a compiler feature, not something that could
be solved with microcode alone>

Second does apply cleanly.
