Test Result (same as ucode-v4)
------------------------------
Tested tip:x86/microcode (top commit 9975802d3f74) on an Intel Sapphire
Rapids server that both early load and late load worked well. For more
details, please refer to the test below:
Tested Machine
--------------
Intel Sapphire Rapids server with 2 sockets, each containing 48 cores,
resulting in a total of 192 threads.
Microcodes
----------
a) Microcode revisison of CPU : 0xab000130
b) Microcode revision in the initramfs : 0xab000140 // for early load
c) Microcode revision in /lib/firmware/intel-ucode/* : 0xab000160 // for late load
[ Microcode b) & c) headers both contain minirev 0x2b0000a1. ]
Dmesg log
---------
// Early load OK.
[ 0.000000] microcode: updated early: 0xab000130 -> 0xab000140, date = 2022-11-04
...
[ 20.261926] microcode: Microcode Update Driver: v2.2.
...
// Late load OK.
[ 27.400858] microcode: Updated to revision 0xab000160, date = 2022-11-16
[ 27.409978] microcode: load: updated on 96 primary CPUs with 96 siblings
[ 27.409997] microcode: revision: 0xab000140 -> 0xab000160
cpuinfo
-------
cat /proc/cpuinfo | grep -m1 microcode
microcode : 0xab000160
Thanks!
