what's the problem?
We need to find out by adding earlyprintk=keep to the L4Linux kernel command line. Then there should be more text.
Here are the results after adding "earlyprintk=keep" :

but i don't have a file named "dmon", how to fix it?
Check out l4/pkg/dmon from svn and compile.
when i compile dmon, it says: l4/term_server/vt100.h:no such file or directory
did i loss other packages? how to get them?
why are those packages not downloaded together when i download l4-env from svn?

thanks for answerning.
so you means if the multimedia application (a normal user application) can run in host linux, it can also run in l4linux on fiasco-UX?
Basically yes, leaving out the practical issues really getting this to work.

Hi~
according to http://os.inf.tu-dresden.de/fiasco/ux/status.shtml, it says one of the differences between native fiasco and fiasco-UX
is
:
Port I/O and I/O flexpages.
so is it possible to run a multimedia application in l4linux on
fiasco-UX?
(ex: jpeg, mp3 ... etc)
this kind of application seems that it could access hardware
directly(
ex:
speaker or monitor )?
Fiasco-UX and all the L4 programs that are run in Fiasco-UX are
normal
Linux user applications and thus have not more rights than any other Linux program you are running. Directly accessing hardware is not possible with Fiasco-UX, in the same way it's not possible to access hardware directly as a Linux program. I hope this clarifies the question.
