microcode required for Intel 1280P 6-9a-00

まず、issue に記載された CPU シグネチャ、現在のマイクロコードリビジョン、脆弱性の出力を確認し、それらをリポジトリで利用可能な Intel マイクロコードエントリと比較します。Proxmox イメージ上で lscpu と dmesg を使って報告を再現し、Intel 1280P シグネチャがサポートされているか確認します。適切なマイクロコードが利用可能になり、報告されたマイクロコード不足の状態が解消されれば完了です。

Good afternoon, I am using the Proxmox image and as part of the updates I do not receive microcode for correct operation with the Intel I7 1280P processor, microcode is required for Intel 1280P 6-9a-00

Without microcode, I can’t correctly activate the virtualization and SR-IOV functions

The system often reboots without recording errors in the log, and when I try to activate and use SR-IOV I get errors
