Problem about framebuffer configrution

[Altera_Forum]

My devolopmnet borad is altera stratix 1s10,and port the microtranix nios2linux v1.1 in niosII.  

I selected the Graphics support--->Graphics support--->Suppout for frame buffer devices in Linux Kernel v2.6.5-uc0 configuration.Then compile the Kernel,become a error"drivers/built-in.o * In function `fb_mmap': undefined reference to `io_remap_page_range'". How can I correct this error,and config the framerbuffer support in my system?     Tony Zhu  ChonagQing,China

Hi Tony, 

 Please try this: add the following line to the file include/asm/pgtable.h <div class='quotetop'>QUOTE </div>  --- Quote Start ---  #define io_remap_page_range remap_page_range[/b]  --- Quote End ---    these remap functions are actually dummies in uClinux.   Regards, wentao
