I was surprised to see this request as I thought rtw88 is already in the RHEL9 kernel:

[phil@Build64R9 boot]$ cat config-5.14.0-362.24.1.el9_3.x86_64 | grep RTW88

Maybe you have one of the chipsets that is not enabled? Please can you post the device ID pairing?

Acknowledged.

It would appear RH only enabled ePCI devices, not USB or SDIO (I did not even know wireless SDIO devices were a thing!)

Definitely worth enabling the USB devices:

 # CONFIG_RTW88_8822BU is not set
# CONFIG_RTW88_8822CU is not set
# CONFIG_RTW88_8723DU is not set
# CONFIG_RTW88_8821CU is not set

Not sure about the SDIO devices? What do others think - I don't imagine there is much call for them?

To the Makefile, add:

ccflags-y += -DCONFIG_RTW88_USB -DCONFIG_RTW88_8822BU -DCONFIG_RTW88_8822CU -DCONFIG_RTW88_8723DU -DCONFIG_RTW88_8821CU

I don't think SDIO devices are needed. I assume they would probably be used on embedded boards.

I made a package called "rtw88_usb-kmod" in git that has the four drivers and the common USB module. We should have it in testing soon.

We have pushed the following packages to our "elrepo-testing" repo mirrors and should be available shortly.

Please provide feedback.

For 9.3 GA kernel:
kmod-rtw88_usb-0.0-1.el9_3.elrepo.x86_64.rpm
kmod-rtw88_usb-0.0-1.el9_3.elrepo.src.rpm

For 9.3 errata kernels (kernel-4.18.0-513.18.1.el8_9.x86_64 and later):
kmod-rtw88_usb-0.0-3.el9_3.elrepo.x86_64.rpm
kmod-rtw88_usb-0.0-3.el9_3.elrepo.src.rpm

Works perfectly for me!

Thank you for the feedback. We will move the existing packages to the main repo shortly.

I'm closing this issue as fixed, but please open a new ticket if you have any other issues.
