Which SoC has an Xtensa core? The new Soc named R329 use Xtensa core as the arisc role and audio. And the hwspinlock is the same as h3 and h6. Additional, The new RISC-V Soc also use the same hwspinlock. > > Unfortunately, there's been a submission of the same driver earlier this week: > https://lore.kernel.org/lkml/cover.1605693132.git.wilken.gottwalt@posteo.net/ > > It would be great if you could point out whatever issue there is with > that patch series (it looks like the retry delay could be useful for > example). I will test that submission with arisc next week. BTW, which sunxi board you used, I want to used the same board with you. ^-^ thanks -- fuyao
