From 07a54d704e62e2515db0b085d53d13a2f1b1b06a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Lureau?= Date: Wed, 5 Dec 2012 16:15:32 +0100 Subject: spice-qemu-char: write to chardev whatever amount it can read The current code waits until the chardev can read MIN(len, VMC_MAX) But some chardev may never reach than amount, in fact some of them will only ever accept write of 1. Fix the min computation and remove the VMC_MAX constant.
