Subject: runqemu-internal: set mutual exclusiveness for serial and nographic options
X-Git-Tag: 2015-10~1520
X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=8b0527951ab71c4a4dc4d1238cd9e9e60a6eb5ee;p=openembedded-core.git

runqemu-internal: set mutual exclusiveness for serial and nographic options

Use "-nographic" option only if "serial" option is not
specified. Otherwise we get below error when
'runqemu <kernel_image> <rootfs_image> serial' is executed,

(snip)
QEMU 2.2.0 monitor - type 'help' for more information
(qemu) qemu-system-aarch64: -serial stdio: cannot use stdio by multiple
character devices
