Requirements¶

System Requirements¶

Kernel Version¶

Minimum Kernel: 6.17

The DKMS package requires kernel 6.17 or newer. For older kernels, use the patch method instead.

Kernel	DKMS Support	Notes
6.19-rc	Yes	Release candidate
6.18.x	Yes	Recommended
6.17.x	Yes	Minimum supported
6.8 - 6.16	No	Use kernel patches
< 6.8	No	Not supported

Dependencies¶

The following packages are required:

Arch LinuxDebian/UbuntuFedora/RHEL

# Installed automatically by the AUR package
sudo pacman -S dkms linux-headers linux-firmware

# For clang-built kernels (CachyOS, etc.)
sudo pacman -S clang lld

# Core dependencies
sudo apt install dkms linux-headers-$(uname -r) linux-firmware

# For clang-built kernels
sudo apt install clang lld

# Core dependencies
sudo dnf install dkms kernel-devel linux-firmware

# For clang-built kernels
sudo dnf install clang lld

Clang-Built Kernels¶

Some distributions (like CachyOS) build their kernels with Clang instead of GCC. DKMS modules must be built with the same compiler.

To check if your kernel uses Clang:

grep CONFIG_CC_IS_CLANG /lib/modules/$(uname -r)/build/.config

If it shows CONFIG_CC_IS_CLANG=y, install clang and lld. The DKMS build system auto-detects this.

Hardware Requirements¶

Supported Chipsets¶

Chipset	Interface	WiFi Standard	Status
MT7925	PCIe	WiFi 7 (802.11be)	Full support
MT7921	PCIe	WiFi 6E (802.11ax)	Full support
MT7921	USB	WiFi 6E (802.11ax)	Full support
MT7921	SDIO	WiFi 6E (802.11ax)	Full support

Identifying Your Hardware¶

# Check for PCIe devices
lspci -nn | grep -i "14c3:7925\|14c3:7921"

# Check for USB devices
lsusb | grep -i "0e8d:7961"

Example output for MT7925:

03:00.0 Network controller [0280]: MEDIATEK Corp. MT7925 Wi-Fi 7 (802.11be) PCI Express [14c3:7925]

Firmware¶

The driver requires firmware files from linux-firmware:

Chipset	Firmware Files
MT7925	`/lib/firmware/mediatek/mt7925/WIFI_*`
MT7921	`/lib/firmware/mediatek/WIFI__MT7921`

Verify firmware is installed:

ls /lib/firmware/mediatek/mt7925/ 2>/dev/null || echo "MT7925 firmware not found"
ls /lib/firmware/mediatek/WIFI_*MT7921* 2>/dev/null || echo "MT7921 firmware not found"

Update linux-firmware

If firmware files are missing, update your linux-firmware package to the latest version.

Secure Boot¶

If Secure Boot is enabled, DKMS modules must be signed with a Machine Owner Key (MOK).

Check Secure Boot Status¶

mokutil --sb-state

Configure MOK for DKMS¶

Most distributions configure this automatically. If you see signature errors:

Generate a MOK key pair (if not exists)
Enroll the key with mokutil --import
Reboot and complete enrollment
Rebuild DKMS modules

See your distribution's documentation for specific instructions.
