Hi,
but i got this error while running stpm
*tpmrun | l4con/lib/src/contxt.c:63:contxt_init(): *tpmrun | Could not find con at names *tpmrun | main(): Error -3 opening contxt lib -- terminating *tpmrun | *tpmrun | Exiting with -3
this is the command
./fiasco -l names -l dm_phys -l stpm-ux -l tpmrun
Okay, you are using the tpmrun tool. This is a testing and debugging tool and does indeed require the graphical console. You need to add at least the following to the command line if you want to use it:
-l con-ux
(Alex B., are there any additional requirements / things to be taken care of?)
Btw., stpm-ux will try to use the physical TPM of the host platform unless you loaded the kernel module of the TPM emulator instead of a real TPM driver (this worked for older versions of the TPM emulator, I am not sure about later releases).

Hi!
thanks for the info, at the same time, i also give myself a try to port the codes to be able running on l4.hehe:) one more thing, in order to run tpmemulator on ux, does it really need con-ux server?
con-ux is an L4 server that provides virtual graphical consoles. If you want to run con-ux on Fiasco-UX with graphics support, you also need the ux_con binary as Adam explained. However, the TPM emulator itself does not depend on graphical output and you can therefore compile Fiasco-UX without support for the virtual framebuffer. In this case, you do not need ux_con (and con-ux won't work of course).

Hi Ahmad,
if stpm server able to call tpmemulator, so far as i know it can only call physical TPM chip.
There is a STPM backend that can talk to a TPM emulator. However, this backend assumes that STPM is running on top Fiasco-UX and talks to the 'tpmd' daemon using sockets. In this case, tpmd runs next to Fiasco-UX on the Linux host kernel.
We are also porting the TPM emulator such that it can run directly on top of L4, but this is work in progress in a very early stage.
