In the discuss threads [1] [2], new firmware format break user space because older drivers can't recognize new firmware format. To avoid this, the new format will be named rtw89/rtw8852b_fw-1.bin and only new driver try to load it. Old drivers only load original and understandable firmware rtw89/rtw8852b_fw.bin. More, new driver will be still backward compatible with old firmware, so original firmware can be used by new driver. If there is newer firmware format is introduced, rtw89/rtw8852b_fw-2.bin will be given. The same rules will be applied like above. So, we will have firmware like below in linux-firmware in the future. rtw89/rtw8852b_fw-2.bin rtw89/rtw8852b_fw-1.bin rtw89/rtw8852b_fw.bin After this patch, MODULE_FIRMWARE() of 8852A/B/C become rtw89/rtw8852a_fw.bin rtw89/rtw8852b_fw-1.bin rtw89/rtw8852c_fw.bin [1] https://lore.kernel.org/linux-wireless/df1ce994-3368-a57e-7078-8bdcccf4a1fd@gmail.com/T/#m24cb43be31a762d0ea70bf07f27ae96c59f6931b [2] https://bugzilla.kernel.org/show_bug.cgi?id=217207 Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230320130606.20777-4-pkshih@realtek.com
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
