Don't sample the first entry outside the timer as this is a different code path which produces a different offset from the clock tick. Use sys_clock_hw_cycles_per_sec() to be compatible with systems that read their hardware clock frequency at run time. Perform cycle difference computations with uint64_t. If ever the magnitude of the absolute clock cycle values is greater than 52 bits then the cast to a double will actually lose accuracy. Signed-off-by: Nicolas Pitre <npitre@baylibre.com> |
