創建一個新的 DKMS 包時,可以參考下面的指導方針。
包名
DKMS 包的命名方式是:原始包名加"-dkms"後綴。
通常在 $pkgname
後面使用 $_pkgname
記錄不包含 "-dkms" 後綴的軟體包名 (例如 _pkgname=${pkgname%-*}
). 這樣可以在原始的軟體包 PKGBUILD 和 DKMS 編譯文件之間保持相似性。
依賴
依賴的包應該是原來軟體包的基礎上,加上 dkms包。This is important because this will provide tools and hooks that will rebuild the kernel driver provided by the -dkms package whenever the kernel is updated.
不要包含 linux-headers包, – or any other Linux header package – to the PKGBUILD. These headers are already listed as optional dependencies of dkms包 and each kernel package has its own header package, so including header package dependency in the -dkms package is both unnecessarily redundant and restricting。
原始碼構建位置
構建模塊所需原始碼需要放在(這是DKMS構建模塊時使用的默認目錄):
/usr/src/PACKAGE_NAME-PACKAGE_VERSION
在軟體包目錄,要包含一個 dkms.conf
配置文件,告訴 DKMS 如何編譯。這個配置文件需要包含:
-
PACKAGE_NAME
- 實際的項目名稱,通常使用$_pkgname
或$_pkgbase
. -
PACKAGE_VERSION
- 通常使用$pkgver
.
打補丁
為內核模塊原始碼打補丁既可以直接在 PKGBUILD 中進行,也可以通過dkms.conf
來進行。
If patching through dkms.conf
, make sure to install the patches into /usr/src/PACKAGE_NAME-PACKAGE_VERSION/patches/
directory and to add a PATCH[number]=patch_filename
for each patch to be applied, replacing number
with a incremental value starting at 0
. See dkms(8) § DKMS.CONF for more information.
.install 中模塊的自動加載
模塊的加載和卸載必須由用戶自己來執行,設想一下,某個模塊可能在加載的時候崩潰。
Also do not call dkms as it is automatically done via pacman hook provided by dkms包. Pacman 會自動執行 dkms install
和 dkms remove
鉤子。
dkms install
會確保過程結束時執行 depmod
。dkms install
依賴 dkms build
(針對當前內核編譯源碼),build 依賴 dkms add
(添加從 /var/lib/dkms/<package>/<version>/source
到 /usr/src/<package>
的連結)。
例子
這兒有個根據包名字和版本來對dkms.conf
進行編輯,並安裝模塊黑名單配置文件的例子。
其它示例請參考 官方軟體倉庫中的 -dkms 軟體包 和 AUR 中的 -dkms 包。

.install
This example shows a message on post-install and post-upgrade that suggests unloading a conflicting module (example-conflicting-module
) and then loading this package's module (example
) for immediate use, when the user do not want to reboot the system at this moment.
example.install
post_install() { cat<<EOF Unload and load kernel modules: rmmod example-conflicting-module modprobe example EOF } post_upgrade() { post_install }
Module blacklist conf
When it is known that example-conflicting-module
conflicts with this package's example
module, it should be blacklisted:
example-dkms.conf
blacklist example-conflicting-module
