[PULL v2 0/1] Merge tpm 2023/09/12 v2

Posted by Stefan Berger 8 months ago

Hello!

  This PR contains a fix for the case where the TPM file descriptor is >= 1024
and the select() call cannot be used. It also avoids unnecessary errors due to
EINTR being returned from the syscall.

Regards,
   Stefan

I recommend you the b4 tool, see:
https://pypi.org/project/b4/

I had tried to use 'patches' but it doesn't seem to work anymore on the 
python level. So I ended up saving the email via Thunderbird and applied 
it. Maybe that's the mistake? Otherwise I know the b4 tool and typically 
am using it for Linux patches but I see now that there's lore.kernel.org 
for qemu-devel as well. Alright, v3 coming up soon.
