The same can't be said about ARM. From hardware vendor perspective, that leads to a fragmented market, Torvalds said.
"Being compatible just wasn't as big of a deal for the ARM ecosystem as it has been traditionally for the x86 ecosystem," Torvalds said during a fireside chat with ARM developers listening on.
ARM dominates the mobile-device market, and a majority of devices use Android, which is based on the Linux kernel. But there are a lot of fragmentation in the ARM ecosystem, and that's caused support and device issues.
