我正在嘗試啟用 ECC 以確認 RAS 功能ubuntu-18.04
它是GIGABYTE BIOS模式，我檢查了ECC選項，但它不存在。伺服器的詳細資料是：
:~$ lscpu

用於 ECC 檢查的 AMD64 EDAC 驅動程式 複製最新核心「5.3.0-rc1」並啟用EDAC相關配置，編譯並產生debians。
我在 ubutnu18.04 中安裝了核心映像和頭檔 debians。
啟動後我無法列出 edac 模組amd64_edac_mod.ko在“lsmod”中
:~$ lsmod | grep edac
edac_mce_amd 32768 0
檢查 dmesg 日誌，我看到以下錯誤訊息：
[ 17.489578] EDAC amd64: Node 0: DRAM ECC disabled.
[ 17.489580] EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load.
Either enable ECC checking or force module loading by setting 'ecc_enable_override'.
(Note that use of the override may cause unknown side effects.)
[ 17.489584] EDAC amd64: Node 1: DRAM ECC disabled.
[ 17.489585] EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load.
Either enable ECC checking or force module loading by setting 'ecc_enable_override'.
(Note that use of the override may cause unknown side effects.)
但沒有相關日誌AMD64_EDAC驅動初始化
再次檢查驅動程式是否編譯的路徑，如下所示amd64_edac_mod.ko展示。
:~$ ls /lib/modules/5.3.0-rc1-test/kernel/drivers/edac/
**amd64_edac_mod.ko** **edac_mce_amd.ko** i3200_edac.ko i5100_edac.ko i7300_edac.ko i82975x_edac.ko pnd2_edac.ko skx_edac.ko
e752x_edac.ko i3000_edac.ko i5000_edac.ko i5400_edac.ko i7core_edac.ko ie31200_edac.ko sb_edac.ko x38_edac.ko
嘗試手動插入模組，但失敗：
/lib/modules/5.3.0-rc1-test/kernel/drivers/edac$ sudo modprobe -v amd64_edac_mod
insmod /lib/modules/5.3.0-rc1-test/kernel/drivers/edac/amd64_edac_mod.ko
modprobe: ERROR: could not insert 'amd64_edac_mod': No such device
由於上面的驅動沒有安裝，下MC->MC0和MC1記憶體控制器未列出
:~$ ls /sys/devices/system/edac/mc/
power subsystem uevent
請幫我看看驅動程式未安裝的原因？
