wifi: mt76: relicense to BSD-3-Clause-Clear

2025-11-24T13:37:54Z

MediaTek has asked to switch from the ISC license to BSD-3-Clause-Clear, in order to improve clarity and the legal integrity of the code. The BSD-3-Clause license includes the "no endorsement" clause, which is important for protecting the reputation of the original authors and contributors by preventing unauthorized use of their names for endorsement purposes. This clause is absent in the BSD-2-Clause license, which is more permissive but lacks this specific protection. This change also cleans up the license of some Kconfig/Makefile files, which were accidentally marked as GPL. The GPL 2.0 remains in use on mt76x0, as well as two source files in mt7615 for which the license situation still needs to be clarified.

wifi: mt76: fix license/copyright of util.h

2025-11-24T13:37:54Z

The extra copyright line for Ivo van Doorn and GPL license was only there because of code that I had already removed before the initial upstream submission of mt76. Remove it and make this header file use ISC license like the rest of the source files. Link: https://patch.msgid.link/20251008104250.46292-1-nbd@nbd.name Signed-off-by: Felix Fietkau

mt76: add utility functions for deferring work to a kernel thread

2020-09-24T16:10:18Z

In order to avoid keeping work like tx scheduling pinned to the CPU it was scheduled from, it makes sense to switch from tasklets to kernel threads. Unlike a workqueue, this one only allows one fixed worker function to be executed by the worker thread. Because of that, there is less locking and less code for scheduling involved. This is important because the tx worker is scheduled often in a hot path Signed-off-by: Felix Fietkau

mt76: fix wcid allocation issues

2020-05-28T15:57:24Z

mt76 core uses ffs() to find the next free bit. This works well for 32 bit architectures where BITS_PER_LONG is 32. ffs only checks 32 bit values, so allocation fails on 64 bit architectures. Additionally, the wcid mask array was too small in cases where the array was not a multiple of BITS_PER_LONG. Fix this by making the wcid mask array u32 instead and use DIV_ROUND_UP for the size, just in case we ever bump it to a value that's not a multiple of 32.
