I would not go along with telling that we "prefer" base-foc as most of
our scenarios run on all supported kernels. Prominent exceptions are
support for hardware virtualization (only on NOVA and hw/Muen) and
TrustZone (hw only). If you address ARM and x86 alike I'd suggest you
try out base-hw.


I will look into it.

I am interested in Fiasco.OC with Trustzone. I do not prefer pure hypervisor approach i.e. Nova and haven't had a look at Muen. I will like have something like a 'rehosted L4Linux or virtualized Linux' with rest of the stack on something like L4Re, which I believe is the case with foc.

This originates from a recent change in our framework regarding
unifies build directories for all base platforms of a selected
architectur. When running scenarios via "make run/<script>" you now
have to select the kernel by setting the KERNEL option like follows.

  make run/demo KERNEL=hw

Please refer to

  https://genode.org/documentation/release-notes/17.02#Unified_build_directories

for further information.

Got it.

This is indeed strange. The nitpicker mouse pointer always works for
me, but I had one test (in 10) were I could not interact with the
scout window. Could you please run the scenario several times? Please
test by clicking the Qemu window and moving the mouse afterwards. Do
The scout buttons (e.g., forward/backward) change color when the mouse
pointer hovers them?

Yes. This is the exact behavior that I experienced all the three times I tried. I will give it a try. Nothing serious for me at least at this time.

These errors were addressed by a recent commit

  https://github.com/genodelabs/genode/commit/f6386c6ce197185df73d00a63c97d01070754fba

By cherry-picking the commit or applying the patch manually the
exceptions should vanish.

ok.
 

Please note that the current version of the Genode Foundation book
reflects the development state of Genode 16.05. We plan to publish
updates yearly and the next revision will be 17.05.

Got it. Will follow up. Need to get used to semantics of capability lists.
