Hi, It may not be important but I'm trying to make the linux boot log the same for qemu direct kernel loading and loading by u-boot. In armv8 the cntfrq_el0 register is supposed to be written with the system counter frequency. The armv8 manual says it doesn't affect the hardware operation and it's just for S/W to know the frequency. U-boot program writes to that register with COUNTER_FREQUENCY value, when it's defined. In current armv8 virt machine, it's read as 62.5MHz but I coulnd't find where in the source the value is written. Where should I change to value in the qemu source? Thank you.
