<damo22>youpi: the spl() entrypoint may not even be used currently because we stopped using other ipls except 7...
<damo22>the spl.S code is a bit tangled
<damo22>i cant figure out why returning from splx(7) during a simple_unlock_irq(7, &ioapic_lock) allows an interrupt to occur right away
<damo22>in theory, it should never set the interrupt flag
<azert>damo22: the netbsd man page gives some historical background on spl https://man.netbsd.org/spl.9
<azert>they also changed their system between netbsd versions 4 and 5
<azert>You can probably check their code
