Re: Problem with make run/demo & run/hellofor fiasco.oc based build

[Nobody III]

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?

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.

Shahbaz

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.

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

Problem with make run/demo & run/hellofor fiasco.oc based build

[Shahbaz khan]

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.
