I'd like to know how Zircon compares to L4 (implementations).
When I asked Tanenbaum at FOSDEM why he didn't pick L4 for Minix 3, he just got annoyed and seemed to think I was asking why he didn't just use the L4 OS (which doesn't exist) instead of creating Minix 3 - or something. In any case I didn't get a good answer. He could have created his own implementation if he wanted, L4 is just a specification with a few existing high quality implementations that prove the concept...
- ahartmetz 8y agoNote: I think he thought I thought L4 was an OS, I'm pretty sure he knows what L4 is.
- jacksmith21006 8y agoL4 is not capabilities based. Probably the biggest reason was not used. Google is looking at using the capability using a handle to remove some marchalling usually required by the kerrnel to improve IPC improvement beyond L4. L4 has done an excellent job with improving IPC performance but Google looks to take it even further.
