2009 年末 Imac 上的 Ubuntu 22 出现 CPU 错误

Question

我需要一些帮助来修复一台 2009 年末的 Imac，我设法安装了 Ubuntu 22.04（我是这个操作系统的新手），并修复了 Nvidia 卡问题，然后我运行了 CPU 信息并发现了这些信息：

flags       : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good nopl cpuid aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 xsave lahf_lm pti tpr_shadow vnmi flexpriority vpid dtherm

vmx flags   : vnmi flexpriority tsc_offset vtpr vapic

bugs        : cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tf mds swapgs itlb_multihit mmio_unknown

我想知道如何解决错误或我能做什么。以下是完整的 CPU 信息，以备不时之需；

这些不是需要“解决”的软件错误。这些是 Linux 内核已经解决的 CPU 硬件错误。

如果你运行lscpu，你会看到类似

  Itlb multihit:         Not affected
  L1tf:                  Not affected
  Mds:                   Not affected
  Meltdown:              Not affected
  Mmio stale data:       Not affected
  Retbleed:              Not affected
  Spec store bypass:     Not affected
  Spectre v1:            Mitigation; usercopy/swapgs barriers and __user pointer sanitization
  Spectre v2:            Mitigation; Retpolines, STIBP disabled, RSB filling, PBRSB-eIBRS Not affected
  Srbds:                 Not affected
  Tsx async abort:       Not affected

无论如何，用户都无能为力。
