Daniel Verkamp 8eb944b480 devices: proxy: do not acknowledge write commands ... Write accessess cannot fail (in the CommandResult sense) and the result did not carry any data, so remove the response from the Write command. This should improve the speed of write requests for sandboxed devices. For example, with the sandboxed serial device, boot time with a release build of crosvm on my workstation goes from 1.7 seconds to 1.2 seconds, measured by timing a boot with a missing init so that the kernel panics and shuts down immediately. BUG=None TEST=time crosvm run -p init=bogus vm_kernel Change-Id: I125bb831235ca741ae1cc6c86a02a5d863d1a211 Signed-off-by: Daniel Verkamp <dverkamp@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/1853970 Reviewed-by: Zach Reizner <zachr@chromium.org> Tested-by: kokoro <noreply+kokoro@google.com>		2019-10-14 23:59:49 +00:00
