From fd164dcc31aa6c60e9834036a7cfcea5411daa3d Mon Sep 17 00:00:00 2001 From: Randy Witt Date: Thu, 20 Aug 2015 13:01:25 -0700 Subject: qemurunner: Use two serial ports and log console with a thread qemu can freeze and stop responding if the socket buffer connected to a tcp serial connection fills up. This happens of course when the reader of the serial data doesn't actually read it. This happened in the qemurunner code, because after checking for the "login:" sentinel, data was never again read from the serial connection. This patch solves the potential freeze by adding a thread to continuously read the data from the console and log it. So it also will give a full log of the console, rather than just up to the login prompt. To simplify this patch, another serial port was also added to use for the sole purpose of watching for the sentinel as well as being the interactive serial port. This will also prevent the possibility of lots of debug data on the console preventing the sentinel value from being seen due to interleaved text.
