ARM multiprocessor support
- diyorgasms 12y agoI am disappointed not to see any of the Beagle* boards on the list of supported devices, as it is another ARMv7 device with completely open hardware. Still, this is a pretty cool consolidation effort.
- markatto 12y agoThe beagle{bone,board} use single-core OMAP3 derivatives; they don't require multiprocessor support and were already supported.
- Alupis 12y agoOther boards will undoubtedly get support over time. Every single board requires a different setup, often times dtb, special boot loaders or u-boot, special kernels, etc. Give it time. Wandboard will be exciting once they support that. http://www.wandboard.org/index.php/details http://www.wandboard.org/index.php/details

- fidotron 12y agoWhile welcoming this, it's amazing this kind of thing is news. That so many communities failed to acknowledge the inevitable rise of SMP systems still amazes me. This blind spot basically killed OCaml, which has fantastic single thread performance, and it remains a serious problem for things like Python. The same thing is now happening with the rise of GPGPUs.
- pjmlp 12y agoThere are many more ways to concurrency and parallelism than threads.
- 4ad 12y ago> That so many communities failed to acknowledge the inevitable rise of SMP systems still amazes me. What? NetBSD most certainly didn't fail to acknowledge the inevitable rise of SMP systems. These boards lacked SMP support because SMP support is a lot of work, every chip is different (unlike x64), very few people know how to work on this, there are very few people working on the NetBSD kernel, and most chips don't have open documentation. You make it sound like these people were like "SMP... shit, who needs this?".
- na85 12y agoI would love to run a *BSD as my daily driver on my X220, but battery life is important to me and everything I've read suggests that most BSDs don't perform as well as Linux + TLP,
- bch 12y agoI run Net on my t420, and I like it. I feel like I get ~3 hours (I don't keep hard time) using it, and it'd be fair to say typical use is development, w/ web (ie: running X, vi, clang, and various text-processing tools, Firefox, and disk/network intensive things like syncing code-repositories). I've got a 9-cell battery. I'm running -current. Now that -current is also offloading rendering to my integrated i915 gfx, I'll be curious to see how screen-intensive work will impact battery. The joy I get from NetBSD has outweighed various temptations from other OSes. I've dabbled w/ Ubuntu and others, but they're not compelling enough to switch. If you've got any questions, I'm happy to try to answer.
