From eabbdb3c4f78ab23348a6b988f59d9d98b5e2c7c Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Sat, 20 Feb 2021 14:52:21 -0800 Subject: runqemu: Add new option to disable vga emulation When using nographic, explicitly disabling vga is needed some cases since some qemu firmware (OpenFirmware ) defaults to std vga, and when vga is enabled then it disables output to serial and redirects that to vga which is by design, hwoever we expect the console output to go to serial when using nographic, therefore its important to disable vga with nographic especially on qemu based ppc platforms Signed-off-by: Khem Raj Cc: Alexander Kanavin Signed-off-by: Richard Purdie --- scripts/runqemu | 3 +++ 1 file changed, 3 insertions(+) diff --git a/scripts/runqemu b/scripts/runqemu index dd92a64553..532f2e338d 100755 --- a/scripts/runqemu +++ b/scripts/runqemu @@ -65,6 +65,7 @@ of the following environment variables (in any order): MACHINE - the machine name (optional, autodetected from KERNEL filename if unspecified) Simplified QEMU command-line options can be passed with: nographic - disable video console + novga - Disable VGA emulation completely sdl - choose the SDL UI frontend gtk - choose the Gtk UI frontend gl - enable virgl-based GL acceleration (also needs gtk or sdl options) @@ -489,6 +490,8 @@ class BaseConfig(object): elif arg == 'egl-headless': self.set_dri_path() self.qemu_opt_script += ' -vga virtio -display egl-headless,show-cursor=on' + elif arg == 'novga': + self.qemu_opt_script += ' -vga none' elif arg == 'serial': self.kernel_cmdline_script += ' console=ttyS0' self.serialconsole = True -- cgit 1.2.3-korg
