Subject: Ppc to PowerPC changes relating to XGPIO
Date: Mon, 4 Oct 2010 11:33:05 +0200 [thread overview]
Message-ID: <201010041133.05945.dargaud@lpsc.in2p3.fr> (raw)
Hello all,
when I was using the PPC kernel a couple versions back, I had modified the
xgpio_ioctl.h file (and its related adapter.c) in order to extend the
xgpio_ioctl() function with new commands for my needs.
But now I don't see where the equivalent code is located with the new
architecture. How do I interact win GPIOs from usermode if not for ioctl calls
? (I need to manipulate the direction bits, not just read/write values).
Note: I'm using the kernel provided by the Xilinx git, so maybe my question
isn't relevant here.
Thanks
