Hi,
I am trying to run two rumprun instances on seL4. I called launch_process(bin_name, CONFIG_RUMPRUN_COMMAND_LINE, 1); launch_process(bin_name, CONFIG_RUMPRUN_COMMAND_LINE, 2); in run_rr() of rumprun-sel4-demoapps/roottask/src/main.c.
Then I got below: <<seL4(CPU 0) [decodeCNodeInvocation/107 T0xffffff801fe14400 "roottask" @4166c1]: CNode Copy/Mint/Move/Mutate: Source slot invalid o> sel4utils_move_cap_to_process@process.c:157 Failed to move cap
<<seL4(CPU 0) [decodeX86PortControlInvocation/147 T0xffffff801fe14400 "roottask" @451efa]: IOPortControl: Some ports in range alread> arch_copy_IOPort_cap@arch.c:25 Failed to get IO port cap for range cf8 to cff
I don't understand why I got these errors. launch_process() gets rump_process_t *process from process_from_id(id) so I should get a different slot with the different process id.
