[Qemu-devel] [PATCH V2 05/10] qdev-monitor: print the device's clock with info qtree |
Date: |
Thu, 26 Jan 2017 10:47:35 +0100 |
From: KONRAD Frederic <address@hidden>
This prints the clock attached to a DeviceState when using "info qtree" monitor
command.
For example:
bus: main-system-bus
type System
dev: xlnx.zynqmp_crf, id ""
gpio-out "sysbus-irq" 1
gpio-out "RST_A9" 4
qemu-clk "dbg_trace" 0.0

qemu-clk "topsw_lsbus" 0.0
qemu-clk "dp_audio_ref" 0.0

qemu-clk "dp_video_ref" 1428571.4
qemu-clk "vpll_clk" 50000000.0
