as mentioned before i'm writing a char module for L4linux.
I want the L4Linux driver to communicate over l4_ipc to another L4-Task.
Well, there's a compiler error:
Building modules, stage 2.
MODPOST 1 modules
ERROR: "l4_utcb_wrap" [drivers/char/myDrv.ko] undefined!
This appears, when trying to write in mr.
l4_msg_regs_t* mregs = l4_utcb_mr_u(utcb);
mregs->mr = 23; // if i comment this line, build works.
I doesn't crash at runtime, it just don't compile.
BTW: Adam made a hint to use L4XV_FN* wrappers.
When to use them, and what are they for?
