编译内核后，当我输入 时make modules_install，不仅模块会被复制到 中/lib/modules/，固件也会被复制到 中/lib/firmware/。以下是输入后输出的结尾make modules_install：

碰巧，我需要 ATI radeon 显卡的固件。但我已经有了固件，/lib/firmware/并且我不希望构建该固件。我在内核中选择了以下选项：
[*] Select only drivers that don't need compile-time external firmware
[*] Prevent firmware from being built
那么为什么还要构建固件呢？
另外，我如何找出我的卡需要哪一个固件？我可以在 my 中看到以下消息dmesg，但这并没有告诉我加载了哪个文件：
[drm] initializing kernel modesetting (RV620 0x1002:0x95CF 0x1002:0x2143).
[drm] Loading RV620 Microcode
有没有办法列出已加载的固件，就像我列出已加载的模块一样（lsmod）
澄清：
总结我的问题：我有ATI RV620 (FirePro 2260)显卡并且正在使用 kernel 3.12.20。如何准确找出我的卡需要加载哪些固件文件？
# lspci | grep -i vga
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV620 [FirePro 2260]
答案1
您可以尝试以下命令之一：
modinfo -F firmware `lsmod | tail -n +2 | cut -f 1 -d ' '`
或者
lsmod | tail -n +2 | cut -f 1 -d ' ' | xargs modinfo -F firmware
