Hi all, I am trying to implement vrfb based rotation for the git omapfb driver.
It requires change of fb_fix_screeninfo ( Physical address of fb and such things) and fb_info (virtual address of buffer) because different rotation angles require different physical addresses for VRFB based rotation. Moreover this changes has to be done dynamically. In the current implementation it assumes the framebuffer position (address) is not changed and passes the control to DSS (dispc.c) to rotate the framebuffer. This will work nicely for controllers (eg blizzard) which changes some register bits for rotation. Can anybody suggest me some hints how to implement this dynamic changes?? Currently i am planning to do all vrfb initialization stuff in omap_dispc_init. But i am getting confused how to manage the changes for fb_fix_screeninfo dynamically for different angles, even though the ultimate aim is to program the DMA and SMS.
