Here is an example I have created showing how to use set the cache_modeled_state: http://community.validation.linaro.org/scheduler/job/2637/definition > Is this it correct for me to assume that this corresponds to the kernel > command line arguments passed via UEFI? > > > > - Arguments: console=ttyAMA0 earlyprintk=pl011,0x1c090000 debug > user_debug=31 loglevel=9 root=/dev/vda2 > > > > Can anyone please confirm? > The kernel arguments are hard coded into the UEFI configuration. You can override these values with interactive boot commands. Here is an example of this on an older model: http://community.validation.linaro.org/scheduler/job/1552/definition The new models have slightly different menu options so you will have to modify the send / expect logic to handle these differences. > > > > > > > > > On a related theme, I can see the following being defined in the > dispatched device_type def > > > > simulator_dtb = fvp-base-gicv2-psci.dtb > > > > and then this getting subsequently used in the UEFI fdt argument > > > > - FDT: VenHw(C5B9C74A-6D72-4719-99AB-C59F199091EB)/fvp-base-gicv2-psci.dtb > > > > *Q2.
