[Qemu-devel] [PATCH 19/19] unicore32-softmmu: Add a minimal curses screen support |
Date: |
Tue, 7 Aug 2012 18:00:59 +0800 |
From: Guan Xuetao <address@hidden>
This patch adds a minimal curses screen support for unicore32-softmmu.
We assume 80*30 screen size to minimize the implementation.
Two problems are not solved, but they are innocuous.
1. curses windows will be blank when switching to monitor screen and back
2. backspace is not handled yet
v1->v2: add extra handler for '\r'
