[PATCH 2/3] qdev-monitor: Display frequencies scaled to SI unit |
Date: |
Sun, 27 Sep 2020 11:08:19 +0200 |
Since commit 9f2ff99c7f2 ("qdev-monitor: print the device's clock
with info qtree") we can display the clock frequencies in the
monitor. Use the recently introduced freq_to_str() to display
the frequencies using the closest SI unit (human friendlier).
Before:
(qemu) info qtree
[...]
dev: xilinx,zynq_slcr, id ""
clock-in "ps_clk" freq_hz=3.333333e+07
mmio 00000000f8000000/0000000000001000
After:
dev: xilinx,zynq_slcr, id ""
clock-in "ps_clk" freq_hz=33.3 MHz
mmio 00000000f8000000/0000000000001000
