Noise problem after Frame Buffer enlargement

Hi everyone,

    I tried to enlarge frame buffer size in boot argument as following:

Before:

video=davincifb:osd0=720x576x16,2500K

After:

video=davincifb:osd0=1024x768x16,3072K

 

After this change, there will be some noises on screen during earlier stage, and the system will always work slowly.

1. Is there any other section should be modified to fit this change in IPNC code structure?

2. Is there any constraint about frame buffer size?

3. Is there any method to relieve the situation if OSD0 in 1024x768 is needed?
