In previous time, Samuel proposed me to set a "bound processor", to force that booting use only BSP, and the AP will be using once booting are finishing. But I don't remember fine how to do it.
Also we found that ext2fs had a thread which was never assigned to any processor, but we never discover the reason. Check latest commits of this branch, in which I working together with Samuel (who told me indications via IRC) in this. https://github.com/AlmuHS/GNUMach_SMP/commits/wip El mié, 1 feb 2023 a las 12:53, Damien Zammit (<dam...@zamaudio.com>) escribió: > > -------- Original Message -------- > On 1 Feb 2023, 10:35 pm, Almudena Garcia < liberamenso10...@gmail.com> > wrote: > Ok.
