Hi All,
In Android we are using BOARD_KERNEL_CMDLINE, for different things.
I know what is kernel command line, and how it is used. But why
another cmdline is required in android.
Please tell me..
THanks in advance

Hi Qingwei,
The correct way is to modify in your frame buffer display driver , just swap
between B and R
The frame buffer display driver is in your linux kernel driver
/linux-xxx/drivers/video

Hi, Dang,
We’re using driver/video/mxc/mxc_ipuv3_fb.c as framebuffer driver, and I think
the only thing I should do is modify check_var to re-define fb_bitfield, right?
Or I should modify other file? Could you please give a example or further tips?
Thanks a lot!

/dev/alarm is necessary. It comes from a kernel patch called android
alarm. you have to patch it to regular kernel on your own.
Without it, AlarmManagerService will have trouble to setup alarm.
RTC is rarely referred directly in android. however, SystemServer will read

Hi QingWei,
Last time I tried to swap the color on Android VNC Server, which use the
virtual frame buffer driver in kernel/drivers/video/vfb.c
In your case, you should do the same with your FB driver. You should check
your kernel boot parameter also, to make sure the input setting for your

we ported android 2.3.1 to our architecture and board. the response time is
terrible up now.
according to my profile, i think it's because drawing windows are very
slow. i have 2 clues which drawed my idea on graphics:

ideally, bootanimation is 12fps. however, we can
If the boot animation is that slow, your graphics driver is very broken.

Hi Tung,
Thank you!
I have ever done the similar thing with our FB driver, but it did not take
effect. Maybe our platform made some special changes, or driver has bugs. I’ll
check them carefully.
BTW, I wonder if there is another way to implement, e.g. modify fbmem.c or
other files.
