Interrupts and timers are actually codified in the specifications, unlike most other ISAs.
- ajross 4y agox86 APIC/TSC is actually very well specified. As is older stuff like HPET. Even the original IBM PC PIT had a clean datasheet and documented board integration.
- snvzz 4y agoYes, and that's unlike ARM or MIPS. RISC-V and OS-A 22 platform are different than x86 & the IBM PC platform in that it has put effort into ensuring these things are standardized from the very start.
