embdenHello, I was reading the third task here: https://wiki.linuxfoundation.org/gsoc/2019-gsoc-agl and I have a question : what is meant by "partitioning hypervisor 'jailhouse'"?09:11

AlisonChaikenembden, are your familiars with hypervisors like Xen or KVM?  jailhouse is an alternative to them.18:39
embdenAlisonChaiken: I thought that Jailhouse is a concept that can be implemented via hypervisors.18:45
AlisonChaikenJailhouse is a kind of hypervisor.   It replaces KVM or Xen.18:46
AlisonChaikenI recall that there have been talks at Embedded Linux Conference about it.  You should be able to find the slides and the video.18:47
embdenAlisonChaiken: is it like a L4 but Linux only?18:57
AlisonChaikenHmm.   You'd be better off reading the LWN article, the _Linux Journal_ article, or watching the vid than asking me!18:58
AlisonChaikenThere is a ton of info about it.18:58
embdenAlisonChaiken:  thanks, it  is just wierd to call something "Jailhouse". Try to look for it in Google - learn more about prisons!19:00
AlisonChaikenIf you search for "Jailhouse hypervisor slides" you'll be on the right track.19:01
AlisonChaikenIf you add "site:lwn.net" or "site:linuxfoundation.org" then there will be no prison hits.19:02
embdenAlisonChaiken: I mean it's hard to find a comparison not with Xen but with the same class players like seL4.19:04
AlisonChaikenseL4 is 'formally verified'.   It is in a class all by itself.   Jailhouse has a reputation for being less featureful but correspondingly less complex (which usually means less buggy).19:05
AlisonChaikenThat's about all I know about it.   KVM is the only hypervisor I've actually used.   Oh, and Green Hills.19:06
embdenAlisonChaiken: but there is a whole family of L4 hypervisors. Anyway, that's not what I want to do during GSoC - Zephyr+Jailhouse, thanks for your help!19:07
