It's been a while since I did any porting so things may have changed (donut and eclair). I just did graphics, no other devices (sound, gps, accelerometer, etc.). Specifically, I added support for an 555 RGB in 16 bits screen.
I found that Android is mostly forgiving of the Linux kernel version as long as you have the correct Android specific kernel patches applied. I applied the Android kernel patches to the board supplied kernel sources. Here is the list of Android files I changed for framebuffer support. It may be under or over kill but I did get correct images on the screen (until Android crashed running out of RAM): simulator/app/PhoneData.cpp include/core/SkBitmap.h src/gl/SkGL.cpp cmds/bootanimation/BootAnimation.cpp core/jni/android/graphics/NinePatchImpl.cpp core/jni/android/opengl/util.cpp core/jni/android_view_Surface.cpp core/jni/com_google_android_gles_jni_EGLImpl.cpp graphics/jni/android_renderscript_RenderScript.cpp include/ui/PixelFormat.h libs/rs/rsAllocation.cpp libs/rs/rsScriptC_Lib.cpp libs/rs/rsUtils.h libs/surfaceflinger/Layer.cpp libs/surfaceflinger/LayerBase.cpp libs/ui/GraphicBufferMapper.cpp opengl/include/GLES/gl.h opengl/include/GLES2/gl2.h opengl/libagl/copybit.cpp opengl/libagl/egl.cpp opengl/libagl/mipmap.cpp opengl/libagl/texture.cpp include/hardware/copybit.h include/hardware/hardware.h modules/gralloc/framebuffer.cpp modules/gralloc/gralloc.cpp modules/overlay/overlay.cpp include/pixelflinger/format.h libpixelflinger/buffer.cpp libpixelflinger/codeflinger/texturing.cpp libpixelflinger/format.cpp On Aug 1, 10:09 pm, Frank <[email protected]> wrote: > Dear all, > > I have some question want to clarify about the android porting > process. > Do we have any files or directory which is hardware independent or > kernel specific? > > I am appreciate to have some discussion and suggestion in there. > > Thanks -- unsubscribe: [email protected] website: http://groups.google.com/group/android-porting
