[OpenIndiana-discuss] : Touchscreen support

[Jerry Kemp]

I think it is a fine request.

And, I would take your comment one step further.

If we had touchscreen drivers....And since the Solaris port to ARM
functional as of 2009 (see additional email note from Eric Trimble at
bottom), put the two together, and we could have Solaris on the iPad/iPad 2.

Open mouth, insert foot.

The ARM port is now functional (and available). I would assume (though I
can't verify) that ZFS support is part of the port.

There are a wide variety of ARM chips, in all sorts of stuff. Given the
performance characteristics of some of the stuff I've been playing with
over the last decade (and a pre-look at an ARM-based netbook), I'd have
to say that any currently-available single-chip ARM-based system isn't
going to be good to run OpenSolaris/ZFS on.

That said, I can certainly see some really, really good uses for
ARM-based microcontrollers as the guts of an HBA.   They're likely good
enough to do something like a tiny computer-on-a-board setup.  Think
something like a Sun 7110-style system shrunk down to a PCI-E controller
- you have a simple host-based control program, hook a disk (or storage
system) to the ARM HBA, and you could have a nice little embedded ZFS
system.

Either that, or if someone would figure out a way to have multiple-chip
ARM implementations (where they could spread out the load efficiently).
