thank you for your reply.I understand.
Also I want to know how to make a delay in qemu.
For example, when I send a UART data, there is a certain time interval from
setting the register to when the data is sent. Most of this time does not
affect the simulation effect, but some guest firmware will e

In the controller, QEMUTimer will be used in the implementation of timer
simulation.
I wrote an auto-loading timer with a period of 1ms and the clock source
used is QEMU_CLOCK_VIRTUAL. But it doesn't seem to be very accurate,
because the actual time after I accumulated it to 500 times took about
7
