Subject: [PATCH 1/4] qdev-monitor: Display frequencies scaled to SI unit
Date: Tue, 20 Oct 2020 20:20:05 +0200	[thread overview]
Message-ID: <20201020182008.2240590-2-f4bug@amsat.org> (raw)
In-Reply-To: <20201020182008.2240590-1-f4bug@amsat.org>

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
