We are going to submit V4 system emulation, maybe tommorrow or next-week, and We'll keep updating the linux-user portions. I believe what Richard meant is suggesting you to re-order your patches so that the CPU emulation part (first half of this series) and the system emulation part (Xiaojuan's series) would be combined to one new series, to be reviewed and merged independent of the still-unstable Linux ABI that's blocking this series at the moment. To "keep updating the linux-user portions" without re-arranging the series will just delay inclusion further, IMO. In case the description above is not clear enough: We basically have 3 parts for full LoongArch target support: (a) CPU emulation, (b) privileged architecture & hw emulation, and (c) linux-user emulation. Currently this series consists of (a) and (c), while Xiaojuan's series has (b). And the tcg-dev branch you seem to be staging your work at [1] has the same ordering: (a) then (c) then (b), which is consistent with Xiaojuan's series cover letter. However, because (c) is blocked by kernel port upstreaming, (a) could not be merged, and by re-combining (a) with (b) we can speed up review and inclusion of things. This would require you to coordinate with Xiaojuan and reorder your patches in the tcg-dev branch, so that you can generate the right series to send.
