Hi,
I have a terminal configured (rpi4) and I want to shared a file
system with another unix machine. I changed the service to cpu and
configured it to start rio, mounting the draw device and mouse first.

All good but after creating some windows, rio will go crazy, windows
will be resized randomly and the display will not represent the
contents of the windows anymore.

The console message when the party starts is

rio: setname failed: unknown id for draw image

If one is able to kill rio you can start it again and all will be
normal until the mess starts again.

It puzzled me because I'm pretty sure I had this very same issue
the last time I used 9front a lot of years ago on a pc.

I would appreciate if someone points me to a reason of this behavior.

Regards,
adr.

After following the boot process it's clear that the constrains are in the kernel,
I suppose is here /sys/src/9/bcm/main.c#245
	if(!cpuserver)
		/*
		 * give terminals lots of image memory, too; the dynamic
		 * allocation will balance the load properly, hopefully.
		 * be careful with 32-bit overflow.
		 */
		imagmem->maxsize = kpages;

Instead of changing the service variable on bootargs and configuring the cpuserver to run rio,
I'll configure the terminal to run the cpu services.

Just in case someone is thinking about this.

Have you tried sshfs(1) - thats what I use for transfering files to and from UNIX.

Sure, but first I have to configure the terminal to serve files,
so I configured it first to cpu and found that problem with rio.
