What OS is ROCK Pi S running?

Currently we have Debian Buster, Armbian and Slackware Linux running on ROCK Pi S.

Can I ssh to ROCK Pi S running official Debian?

Yes, you can. The ROCK Pi S is shown as rockpis.local in your local network. Check out the Using SSH page.

For ROCK Pi S Ubuntu/Debian system images, the kernel reserves a lot of RAM (about 89 MB), can I reclaim some RAM back?

Yes. The solution is to add "swiotlb=1024" to the kernel command line. It should let you reclaim 62MB of RAM. See this Radxa forum post.
Take the latest ROCK Pi S Debian system as an example, add the following line at the end of file /boot/uEnv.txt.
