From 8a9c8b08cf7b1bf911af181580b7045cb65af5df Mon Sep 17 00:00:00 2001 From: Pekka Paalanen Date: Tue, 28 Mar 2017 18:14:37 +0300 Subject: [PATCH] weston: add --drm-device option for DRM-backend Developers with testing rigs having multiple graphics cards plugged in often want to test things on a specific card. We have ways to choose a card through seat assignments, but configuring that run by run is awkward. Add a command line option for opening a specific DRM device. v2: call it --drm-device instead of --device Signed-off-by: Pekka Paalanen Reviewed-by: Daniel Stone --- compositor/main.c | 2 ++ man/weston-drm.man | 7 +++++++ 2 files changed, 9 insertions(+) diff --git a/compositor/main.c b/compositor/main.c index 32fb33e8..7feb4cb0 100644 --- a/compositor/main.c +++ b/compositor/main.c @@ -565,6 +565,7 @@ usage(int error_code) "Options for drm-backend.so:\n\n" " --seat=SEAT\t\tThe seat that weston should run on\n" " --tty=TTY\t\tThe tty to use\n" + " --drm-device=CARD\tThe DRM device to use, e.g. \"card0\".\n" " --use-pixman\t\tUse the pixman (CPU) renderer\n" " --current-mode\tPrefer current KMS mode over EDID preferred mode\n\n"); #endif @@ -1225,6 +1226,7 @@ load_drm_backend(struct weston_compositor *c, const struct weston_option options[] = { { WESTON_OPTION_STRING, "seat", 0, &config.seat_id }, { WESTON_OPTION_INTEGER, "tty", 0, &config.tty }, + { WESTON_OPTION_STRING, "drm-device", 0, &config.specific_device }, { WESTON_OPTION_BOOLEAN, "current-mode", 0, &wet->drm_use_current_mode }, { WESTON_OPTION_BOOLEAN, "use-pixman", 0, &config.use_pixman }, }; diff --git a/man/weston-drm.man b/man/weston-drm.man index d7fd5614..75d79021 100644 --- a/man/weston-drm.man +++ b/man/weston-drm.man @@ -91,6 +91,13 @@ will understand the following additional command line options.
