I see an image at bell labs for the raspberry pi.
http://plan9.bell-labs.com/sources/contrib/miller/9pi.img.gz
I see that there are Raspberry Pi 2 Model Bs and Raspberry Pi 3 Model Bs
for sale. Will either one work with that image?
I have a Samsung SyncMaster E1920 I could use, it's got an 'HDMI'
connection, I believe. Am I good to go?

a quick and easy way to get a local Plan 9 terminal is to use 9Pi
(Plan 9 on Raspberry Pi). with Go 1.6 and later you can cross compile

Either I'm going insane, the default Plan 9 /dev/draw in-memory
implementation
doesn't implement draw(3), or possibly both.
When I do the following, it works as expected under both drawterm
and a locally mounted instance:
1. Allocate a screen with an 'A' message
2. Allocate an image on the screen of the same size as /dev/wctl
with a 'b' message
3. Draw the image over the window with a 'd' message
4. Flush the buffer with 'v'
When I do the following, it works under drawterm, but not with a
local /dev/draw implementation:
Steps 1-2 above
3. Allocate another image of some arbitrary fill colour with 'b'
(with or without the repl bit)
4a. (Optional, doesn't seem to make a difference) set the
compositing operator with 'O'
4b. Draw the new image over a portion of the window image from step
2 with 'd'
5. Go to step 3-4 from the first variation.
(I don't have a 9front instance to test on.)
On the other hand, replacing a portion of the image from step 2 with
'y' works under either. (I haven't gotten around to using 'Y' when
appropriate yet.)
Basically, I can only get any variation of this code:
https://github.com/driusan/exp/blob/18a78a1549541d46d26cb6088a904585c386d812/shiny/driver/devdrawdriver/uploadimpl.go#L50
to work under drawterm.
The end result is that under a local Plan 9 instance the basic
sample shiny test looks like this:
http://driusan.github.io/plan9/basicmem.png
Instead of this:
http://driusan.github.io/plan9/basicdrawterm.png
Does anyone have any pointers? I don't have much access to a
physical Plan 9 machine, so I'm having trouble debugging this since
it works under drawterm (or perhaps is buggy under drawterm in a way
that makes it seem like it's working..)
It would also potentially be helpful if someone who uses Go under
9front could let me know how x/exp/shiny/examples/basic looks with
the shiny driver in that branch, but I'm not sure that it matters
since it'll most likely be the same as one of the above..
