Reply-To: surendra.yadav@softdel.com List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hi all, I am writing framebuffer driver using SM501. This graphics driver chip can drive CRT and TFT panel. I have written two seperate framebuffer driver, one for CRT and one for TFT Panel. But I am not able to test both the devices. Any one of them work at a time. I have created two files /dev/fb0 and /dev/fb1. These two can be open successfully and mmap is also successful from userspace. If I am trying to write on fb0 and fb1 with different data, they displayed on either CRT or TFT panel. Can any one help me How to test two different framebuffer devices? Thanks.
