Hi! Sporadically my wifi hangs. Any idea why? This is on a 5.10.0-051000rc2-lowlatency kernel from https://kernel.ubuntu.com/~kernel-ppa/mainline.

I don't get this. Which firmware, si2168 or si2157? I'm still for option 3: If there is a bogus chip revision number it's likely the VG0022A and we can safely set fw to NULL, in which case everything works. All already working devices will continue to work as before. With a low probability there are other devices that will return 0x but a) they didn't work until now and b) they receive a clear message that they return bogus numbers and this works just for the VG0022A, in which case this hardware can be tested. At last, *my* VG0022A will work without a custom kernel which I'm a big fan of. :)) Are there any counterarguments except that it is not the cleanest solution in the universe? ;) -- g

What problem are you seeing here? Why can't you do a > query chip revision first? This was explained here: https://lkml.org/lkml/2017/3/15/778. To quote: If the si2157 is behind a e.g. si2168, the si2157 will at least in some situations not be readable after the si268 got the command 0101. It still accepts commands but the answer is just ff. So read the chip id before that so the information is not lost. The following line in kernel output is a symptome of that problem: si2157 7-0063: unknown chip version Si21255-\x\x\x > This needs resolving of course. I hope so. :) g

I addressed most of these except one "#if 0" warning from checkpatch.

Can you give me a hint how to proceed here? I don't know much about
DVB tuners or kernel development.
I attached the cleaned-up patch for 5.4.0-rc1
Thanks,

DVB-T2 Stick
Hi!
The following patch adds support for the Logilink VG0022A DVB-T2 stick.
After patching and building the kernel it shows up with lsusb and I
used w_scan to scan for channels and vlc for watching.
The original patches were from Andreas Kemnade.
The only thing that doesn't work is wake up after standby.
Do you think you can apply this patch?
Thanks

Complete Linux history in git
I have written a small python script that fetches the linux archive at git://git.kernel.org/pub/scm/linux/kernel/git/nico/archive.git, applies patches up to 2.4.0 and commits every patch to git with a message and a tag. >From there it should be easy to merge old-2.6-bkcvs and the latest Linux git and have a git archive with the complete history. To run it you have to download some patches from http://gonsolo.de/kernel_history/ and start the script from the same directory. It is not perfect, you have to press enter a few times when patches do not apply. I would be happy to receive feedback or patches. After running the script there is a git repository at "kernel" which is approximately 1GB! After running "git gc" (which takes a long time!) the pack file is under 100MB, IIRC. Next step would be to download old-2.6-bkcvs repository from git.kernel.org and merge/rebase (don't know).
