These patches will provide weston randr protocol, its implementation and randr application.
The idea is from xrandr provided by xserver. *Dynamic* mode setting is the main objective of this protocol. Remember, it is one shot operation. For example, if setting the mode, just call one request wl_randr_set_mode without any other operation. With this protocol, weston-wrandr application is developped to help user implement randr protocol in command line just like xrandr command in xserver. For wayland customer, this application could *DYNAMICALLY* do mode setting in command line. For wayland application developer, weston randr protocol provide a external interface to *DYNAMICALLY* do mode setting instead of static configuring weston at the very beginning. Weston protocol wrandr will provide interface to 1) set output mode 2) set output transform 3) move output to relative position 4) provide disconnected output information Currently randr has more functions to be defined and implemented. Some other functions are planned. But at first we need support. If this protocol is accepted, we could have the chance moving on. The advantage is randr architecture have been defined at this commit. New function will be very easy to be added in the protocol. One note: Currently wl_output doesn't provide wl_output_send_name function, I have to implemented it in randr protocol. Actually it will be very easily implemented in wl_output interface. If this commit series is accepted, I will provide the patch to add wl_output_send_name to make issue simply resolved instead of in randr protocol. ' Here are some test cases. 1. weston-randr -q # query all output mode info and disconnected output HDMI3 1)1440x900@60 (current) 2)1920x1200@60 3)1680x1050@60 ... VGA1 1)1280x1024@60 (current) 2)1152x864@60 3)1024x768@60 ... HDMI1 disconnected HDMI2 disconnected DP1 disconnected DP2 disconnected ... 2. weston-randr --output HDMI3 # query HDMI3 output mode info HDMI3 1)1440x900@60 (current) 2)1920x1200@60 3)1680x1050@60 3. weston-randr --output HDMI3 -m 2 # which will set mode as 1920x1200 4. weston-randr --output HDMI3 -R 1 # rotate HDMI3 output 90 degree 5. weston-randr --output HDMI3 -leftof VGA1 # put HDMI3 output leftof VGA1 6. weston-randr --output HDMI3 -rightof VGA1 # put HDMI3 output rightof VGA1 Quanxian Wang (6): Add weston randr protocol Add weston_randr definition and randr_backend intreface Add the detailed implementation of randr protocol Initialize the randr interface in drm backend Add weston-randr application Change the size of Panel and Background after output's is changed clients/Makefile.am | 9 + clients/desktop-shell.c | 60 +++++ clients/window.c | 7 + clients/window.h | 2 + clients/wrandr.c | 642 ++++++++++++++++++++++++++++++++++++++++++++++++ protocol/Makefile.am | 1 + protocol/randr.xml | 151 ++++++++++++ src/Makefile.am | 4 + src/compositor-drm.c | 67 +++++ src/compositor.c | 466 +++++++++++++++++++++++++++++++---- src/compositor.h | 14 ++ 11 files changed, 1376 insertions(+), 47 deletions(-) create mode 100644 clients/wrandr.c create mode 100644 protocol/randr.xml -- 1.8.1.2 _______________________________________________ wayland-devel mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/wayland-devel
