Hi John,
Since you see the GUI, the input drivers (both USB HID and PS/2) have
come up, which is promising.
That's interesting - could the USB driver be initialized, but crash on
an interrupt (or something like that)?
indeed. It looks very much like that.
To take the USB driver off the critical path for using Sculpt, you may
give the attached patch a try. It prevents the input filter from
obtaining an input session from the USB driver. If our assumption is
correct, you should be able to interact with Sculpt using the laptop's
keyboard and track point (driven by the PS/2 driver).
That worked! Now the mouse pointer works, the Manager panel responds to
clicks, and the NVMe drive seems to be working (i.e. the partitions show
up in the Manager panel).
Unfortunately, there are two new problems:
1. The "Inspect" buttons toggle, but the Inspect window doesn't open for
any drive / partition.
2. I can't seem to connect to a network. I have the most hope for the
built-in Wi-Fi, but it gets stuck on "Scanning...".
This just goes to show how dependent we are on USB - I can't think of a
way to get data on or off this machine without it. (No optical drive,
and I didn't buy the dongle for the "mini-ethernet" port.)
It's a little strange that it boots off the USB stick all the way
through displaying the component graph. I'm assuming it uses the BIOS
up to a certain point, then hands control over to the Genode drivers.
The boot image is loaded into memory by the boot loader, which uses BIOS
calls. Genode's USB driver is not used at this stage.
If we can pinpoint the problem to the USB driver, there is still the
open question of how to investigate it. I hope that the ability to
interact with Sculpt will give us some clues, in particular by looking
at /report/log in the inspect window.
It's interesting that the log output stops after about 8 lines (none of
which seem to be errors), and nothing after that generates log output.
But if we can figure out how to open the Inspect window, I hope to be
able to copy files to/from the NVMe drive, which might help us work
around the USB drive problem.
Thanks!
