Kernel 5.12 support

[ghost]

Hi and great thanks for your work! I cannot build module for kernel 5.12rc1.

[tomaspinho]

Please refrain from using this module with 5.12-rc1 for two reasons:

• That's a release candidate, this module is supporting stable releases
• Linus Torvalds has explicitly discouraged users from using that specific version because of swapfile corruption that may cause data loss on your system

If you were trying that kernel out because of our discussion in the Maintenership thread, please try that kernel with the official rtw88 driver for the time being. I will look into making this compile for 5.12 stable before it's released.

Thank u for answer!

Re-opening as the tracking issue for 5.12 support.

Actually on 5.12_rc2 the WiFI driver made by realtek works without problems, be sure to build it as module

That's really good to hear. Do you know your RFE type?

I need to test it some days or weeks. Now I use 5.12rc2 (Fedora 33 rpm build from koji), on 5.12rc1 was have issue: one time random disconnect and no ability to connect again.

Fix for this module on 5.12-rc2 available at https://github.com/tomaspinho/rtl8821ce/pull/218

Build from new branch was failed on 5.12rc2

Can you provide your build logs? It builds just fine on Ubuntu with the mainline 5.12-rc2 kernel packages.

Run ./dkms-remove.sh and then install.

Same error anyway.

[ghost]

What log report? Anyway you can rebuild kernel with realtor driver builtin

[ghost]

make errors

I testing built-in driver for now from fedora's rpm build.

You have my same error. Set shell language as english and rebuild. It's a regression with language

[tomaspinho]

You have a broken GCC installation. Make sure your installed GCC version matches the one used to build your kernel.

No, the problem is with language. I had that error on gentoo too. You have to run LANG="en_US" and then make. The kernel checks for gcc and ld and if they doesn't match with "GCC GNU" and "ld GNU" it fails to build. Also check this: https://bugzilla.kernel.org/show_bug.cgi?id=212105

[tomaspinho]

@ScardracS were you able to build this module on 5.12?

Was tried to change locale with export LANG="en_US" in console window but it don't help.

On gentoo.

EDIT: Did you mean this made by you or the one made by realtek?

I was asking if you had tried building rtl8821ce (this repository) for the 5.12 kernel.

Oh, ok. No, I haven't tried this one

I confirmed that the official driver from realtek still doesn't work yet on 5.12rc3, Unstable and AP mode broken and all.
Yet this patch works flawlessly. Thank you. It'd be nice if it was merged to master.

[tomaspinho]

Thanks for the report! Merged the PR. Closing this one.
