[PATCH 0/5] hw/mips/loongson3_virt: Implement IPI support

Posted by Jiaxun Yang 6 months, 2 weeks ago

Hi all,

This series enabled IPI support for loongson3 virt board, loosely
based on my previous work[1].
It generalized loongarch_ipi device to share among both loongarch
and MIPS machines. 

Thanks

So far patches 1-3 queued to hw-misc tree, thanks.

Hi Philippe,

Thanks! What's your plan with the rest of the series and earlier MIPS
CPS SMP series?

Let me know if you need help on testing etc.

Thanks

Patches LGTM, but I'd like an Acked-by from Song Gao ;)

No plan, just lack of time :/

Patch 1 - 4:
Acked-by: Song Gao <gaosong@loongson.cn>

and patch2 missed to delete the file loongarch_ipi.c.

Thanks.
