Dear list,
I have started working with Genode, while I am interested in foc based development and it seems the Genode efforts also prefer foc as I have been trying run/demo for builds.
I am facing a few problems. Some that makes sense as a developer, while some are new to me and definitely need some hints to move forward. I have encountered the following errors:
x86_64 (run/demo & run/hello):- Error: target 'core' does not exist. I was not able to figure out how to enable build core but it should have been there by default like other Genode builds.
pba9 (run/demo):- The mouse pointer does not work.
pba9 (run/hello):- [init] Error: Uncaught exception of type 'Genode::Parent::Service_denied'
linux (run/hello):- [init] Error: Uncaught exception of type 'Genode::Parent::Service_denied'
Does the uncaught exception mean that the capability list is not configured properly? I am onto figuring out the build issue of core till your replies.

Hello Shahbaz Khan,

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.

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_directori...
for further information.
pba9 (run/demo):- The mouse pointer does not work.
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?

These errors were addressed by a recent commit
https://github.com/genodelabs/genode/commit/f6386c6ce197185df73d00a63c97d010...
By cherry-picking the commit or applying the patch manually the exceptions should vanish.
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.

Thanks for your prompt reply.

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.

Got it.

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.

ok.

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

I got a bit acquainted with the release notes but I still find it difficult to comprehend what really base-hw means when we say "Genode base -hw" on Muen SK.
I am having some build issues (I do get an image.elf but build does not complete) and have yet not looked into earlier commits and branches so I would appreciate if you can let me know what actually runs over Muen SK in Genode base-hw kernel VM. Does it mean we run another kernel like nova between Muen and virtualbox.
I really like the idea but if we have another kernel below virtualbox than why not run virtualbox on Muen as a subject? I am unable to criticize clearly due to the mentioned confusion.
Thanks.

I've been wondering, is there any reason not to use base-hw_x86_64_muen on regular hardware? It seems to work fine in Qemu, and almost all Genode drivers are in userspace. Is there some limitation that I'm not aware of?
