Subject: New binary rtw8852b_fw.bin not loading firmware not recognized
Briefly,
I use rtw89_8852be in kernel driver
HARDWARE:
Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:b852]
Lenovo Ideapad 1i
ISSUE:
Newest version of binary firmware 2023_03_10,
rtw89/rtw8852b_fw.bin, will not load/firmware not recognized on Linux Kernel 6.2.5 (and others):
[] loading firmare: rwt89/rtw8852b_fw.bin
[] rtw89_8852be 0000:03:00.0: no suitable firmware found
[] rtw89_8852be 0000:03:00.0: failed to recognize firmware
Issue persists regardless of which 6.2 series kernel is used.
All previous rwt89/rtw8852b_fw.bin firmware from linux-firmware 2023_02_10 and earlier loads and works
correctly.
I did file a bug report with the details:
https://bugzilla.kernel.org/show_bug.cgi?id=217207
The firmware format is changed, and wireless-next tree or upcoming 6.3 will
support it. I will also post this information on the bug.
We cannot break user space like that, linux-firmware needs to be
backwards compatible. In other words, anything you submit to
linux-firmware needs to work with old kernels. Should this new firmware
be reverted from linux-firmware?
What about changes in the rtw89 driver? Do they still work with old
firmware?
Kalle,
This is an unfortunate situation that I did not learn about until this week. As
you have seen, my download site has the old firmware.
The latest driver will work with either version of the firmware.
