- GoOnThenDoTell 6y agoThe Linux distros are generally expecting that the hardware supports compressed
- garmaine 6y agoSure, but that’s a single configuration option away from being changed if the hardware is altered.
- rwmj 6y agoNot really, it requires everything to be recompiled, which takes a few weeks assuming you have access to the cluster of RISC-V machines required to do it. We (Fedora) have rejected one platform already that wasn't going to support the compressed extension.
- garmaine 6y agoWhy would you need to do the builds natively instead of cross compiled?
- rwmj 6y agoThe whole toolchain just makes this assumption, and we want to build it the same way Fedora is built for other arches. Plus we're expecting server-class RISC-V hardware soon enough, at least comparable to ARM servers.
