Patch 200 reverted the ath12k conversion from tasklets to BH workqueues.
It arrived with 88f4c32060 ("mac80211: update to version 6.14.11") in May
2025, when main still built kernel 6.6 on 26 targets; BH workqueues only
exist from 6.9, so the revert was doing real work then.
Main now builds 6.12 and 6.18. Both provide system_bh_wq and from_work(),
so there is nothing left for the revert to paper over.
It also leaves the driver inconsistent. backports 7.2 uses intr_wq in
ce.h, pci.c and ahb.c alike, and patch 200 converts only the first two
back to tasklets -- ahb.c was added to the driver after the conversion
landed and never got the same treatment. Building with ATH12K_AHB enabled
therefore fails.
Against pristine backports 7.2 the mac80211 patch series applies 151/151
with this patch removed, and no intr_tq reference survives in ath12k. An
ipq53xx build with ATH12K_AHB enabled links ahb.o cleanly, and the driver
probes an on-chip radio on real hardware.
Bump PKG_RELEASE so existing installs pick up the rebuilt module: it feeds
ABI_VERSION for the kmod packages.

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Download
Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.
If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.
An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:
Development
To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.8+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

different categories. All packages are installed via the OpenWrt package
manager called opkg. If you're looking to develop the web interface or port
packages to OpenWrt, please find the fitting repository below.
