I am testing on a similar Debian system (debian-ports unstable), but 
with a Niagara3 cpu:

Linux gcc102.fsffrance.org 5.10.0-3-sparc64-smp #1 SMP Debian 5.10.12-1 
(2021-01-30) sparc64 GNU/Linux

gcc (Debian 10.2.1-6) 10.2.1 20210110

$ cat /proc/cpuinfo

During "git bisect" I had to apply fixes for unaligned memory access as 
your series starts with TCI code which does not include my patch for 
that. The first bisect step was tested with your tci-next branch, the 
last step was tested with my bisect-tci branch 
(https://gitlab.com/stweil/qemu/-/commits/bisect-tci).
