hi ! Is the ioctl FB_EXEC_FUNCTION still supported by RTEMS ? I only found a #define about it in cpukit/libmisc/fb/fb.h line 26 : #define FB_EXEC_FUNCTION 0x4606
Moreover there is no reference at all to the "struct fb_exec_function" in the rtems source tree anymore My problem is : i need something that allows the user application to switch between single buffered framebuffer mode and triple buffered mode. first i added my own ioctl, then i saw this ioctl (FB_EXEC_FUNCTION) in a french magazine (linux mag) in a nintendo DS app but it seems it's not used anymore. So what should i do to implement this ? add my own ioctl define in my framebuffer driver header ? (that i would have to include in my app) Another problem is that the user app should be able to swap the buffers, at the moment i added another ioctl to do that, but again the FB_EXEC_FUNCTION seemed a much better choice to implement it. If you have any hont about all this do not hesitate to contact me :) ps : a link to the presentation where can be find the nintendo DS app code with the ioctl call http://2009.rmll.info/IMG/pdf/slides_jm_friedt.pdf on slide number 14 -- Yann Sionneau aka Fallenou on irc.freenode.net GSoC 2010 _______________________________________________ http://lists.milkymist.org/listinfo.cgi/devel-milkymist.org IRC: #milkym...@freenode Webchat: www.milkymist.org/irc.html Wiki: www.milkymist.org/wiki
