From: Peter Maydell <[email protected]> Currently the MIPS code uses the old clock_get_ns() API to calculate a time length in nanoseconds: cpu->cp0_count_rate * clock_get_ns(MIPS_CPU(cpu)->clock)
This relies on the clock having a period which is an exact number of nanoseconds. Switch to the new clock_ticks_to_ns() function, which does the multiplication internally at a higher precision.
