Hi, Deng XueFeng, how to enable acceleration with c64x.ko?
#dfbinfo --dfb:system=devmem,video-phys=0x83000000,video-length=691200,accelerator=6400 Though you add "accelerator=6400" at the end of the command line ,I don't think it will work when you run a new program or open a new terminal. May be you could try to add --dfb......... every time ,when you run a program, and make sure DirectFBInit(&argc, &argv) does work. Another way ,you could try davincifb,accel instead of davincifb. Good Luck!

I'am using the default davincifb in the mv 4.0 kernel. but when i search the maillist, I found there is a davincifb: http://www.directfb.org/downloads/Misc/davincifb_2.6.10.tar.bz2 should i use this one and apply the patch in gfxdrivers/davinci? and another question is how to enable acceleration with c64x.ko? seems need a dsp firmware? thanks a lot. > Deng XueFeng wrote: > > [EMAIL PROTECTED]:~# dfbinfo --dfb:system=devmem > > --dfb:video-phys=0x83000000 --dfb:video-length=691200 > > Please try > dfbinfo > --dfb:system=devmem,video-phys=0x83000000,video-length=691200,accelerator=6400 > > > > The additional accelerator setting avoids the probing in the Davinci driver. > > -- > Best regards, > Denis Oliver Kropp > > .------------------------------------------. > | DirectFB - Hardware accelerated graphics | > | http://www.directfb.org/ | > "------------------------------------------" -- Deng XueFeng _______________________________________________ directfb-dev mailing list directfb-dev@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev . = = = = = = = = = = = = = = = = = = = =
