Our LCD device is 480x854.
I've swapped xresol/yresol in kernel frame buffer source code,(not changing cpu MLC resolution register value)
so that it is reported to android to 854 x 480 and make android to prepare screen with landscape mode correctly.
So that when the buffer is actually displayed to frame buffer hardware we rotate 90 degree in android source code by modifiing the following source codes: Sarkari Result TurboTax Rufus
DisplayDevice.cpp::DisplayDevice() constructor source

In that constructor setProjection() method is called with orientation 90 degree.
But the screen is not displayed correctly in landscape mode.

Can you let me know the source code list to change?
Or if patch file is available that will be do enough too for me.

Thank you.

Has anyone worked out if the screen can be used in Landscape mode?

1、Open framework/base/core/res/res/values/config.xml
    Modify config_lidOpenRotation = 0 ;----> config_lidOpenRotation = 90 ;
2、Open framework/base/services/core/java/com/android/server/wm/WindowMangerService.java
    Modify int mRotation = 0 ;-----> int mRotation = 1 ;
3、Open framework/base/services/surfaceflinger/DisplayDevice.cpp
    Modify setProjection(Displaystate::eOrientationDefault, mViewprot ,mFrame )------>
   setProjection( Displaystate::eOrientation90 ,mViewprot , mFrame )
Compile the  source code and fuse successfully, booting the board, but there will be a problem, you can modify as following:

1、Open framework/base/cmds/bootanimation/BootAnimation.cpp
    Modify status_t  BootAnimation::readyToRun                                                 
 spcontrol=session()- >createsurface(String8("BootAnimation"),dinfo.w,dinfo.h.PIXEL_FORMAT_RGB_565);  

 spcontrol=session()- >createsurface(String8"BootAnimation"),dinfo.h,dinfo.w.PIXEL_FORMAT_RGB_565);
2、/framework/native/services/surfaceflinger/DisplayDevice.cpp
   void DisplayDevice::setProjection(intorientation, conts Rect&newViewport,constRect&newFrame)中
if(!frame.isValid()){
frame = Rect(w,h);----->frame = Rect(h,w);
}
Add this code under Transform R:
 orientation = DisplayState::eorientation90
    
3、/framework/native/services/surfaceflinger/surfaceFlinger.cpp
    voidSurfaceFlinger::onInitializeDisplay()：
d.orientation = DisplayState::eOrientationDefault ;----->d.orientation=DisplayState::eOrientatio90;

Compile the source code again.
