amd64_edac_mod.ko（错误检测和纠正驱动程序）未加载最新内核来检查 RAS

我正在尝试启用 ECC 来确认 RAS 功能Ubuntu-18.04

它的 GIGABYTE BIOS 模式，我已检查 ECC 选项，但它不存在。服务器的详细信息是：

用于 ECC 检查的 AMD64 EDAC 驱动程序 克隆最新内核“5.3.0-rc1”并启用 EDAC 相关配置，编译并生成 debian。

我在 ubutnu18.04 中安装了内核映像和标头 debian。

启动后我无法列出 edac 模块amd64_edac_mod.ko在“lsmod”中

:~$ lsmod | grep edac
edac_mce_amd           32768  0

检查 dmesg 日志，我看到以下错误消息：

[   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.)

但没有相关日志AMD64_EDAC 驱动程序初始化

再次检查路径是否编译了驱动程序，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

尝试手动插入模块，但失败了：

/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

由于上述驱动程序未安装，在麦克->麦克0和MC1未列出内存控制器

:~$ ls /sys/devices/system/edac/mc/
power  subsystem  uevent

请帮我找出驱动程序未安装的原因吗？
