Hi, I had a little bit of sleep deprived free time to look into this a bit more. Changes are required to configure, drv/gpio.h and drv/gpio.c
I don't fully understand all of the ramifications of the changes I made (not enough time to read all the google hits) but it does compile which is a start. The changes made are likely incompatible with kernel 2.6 and older due to name changes of functions. Here are the changes: ./configure -> Added an if for Kernel 3.2 drv/gpio.h -> Changed: -#include <linux/autoconf.h> +#include <generated/autoconf.h> Autoconf had moved to generated as per a git commit in 2009: https://forums.virtualbox.org/viewtopic.php?f=7&p=173096 (was the first useful result I could find relating to this) drv/gpio.c This one needed a few amendments first off, line 37: -spinlock_t gpio_spinlock=SPIN_LOCK_UNLOCKED; +spinlock_t gpio_spinlock; The SPIN_LOCK_UNLOCKED doesn't seem to exist anymore, I'm not sure what ramifications not properly initialising this variable will have. Fred/a C programmers input would be nice here. After a bit more Googling other people suggest using: DEFINE_SPINLOCK(gpio_spinlock); instead of the spinlock_t thing. Both methods compile so I'm not sure which to use. Line 403: - ioctl:gpio_ioctl, + unlocked_ioctl:gpio_ioctl, The old ioctl function has been reworked to make it happy about multi-threaded ways of working. As such ioctl doesn't really exist anymore and has been directly replaced with unlocked_ioctl. http://stackoverflow.com/questions/5868908/using-ioctl-communication-between-kernel-mode-and-user-mode http://unix.stackexchange.com/questions/4711/what-is-the-difference-between-ioctl-unlocked-ioctl-and-compat-ioctl Several lines starting from 530: - while(((dev=pci_find_device(GPIO_CBOARDS_VENDOR_ID, + while(((dev=pci_get_device(GPIO_CBOARDS_VENDOR_ID, Simple function rename by the looks of it, finding and replacing all the pci_find_device with pci_get_device gave me 4 hits. Couldn't find any good Google pages for this one except for a guy saying, "replace pci_find_device with pci_get_device." http://forums.xilinx.com/t5/PCI-Express/Linux-Driver-for-xapp1022-and-xapp1052/td-p/104903 Hopefully (message size limit pending) I've attached the three patch files with this email. Hope this helps, I'll be trying to test with real hardware sometime tomorrow. -----Original Message----- From: [email protected] on behalf of Fred Gleason Sent: Tue 20/11/2012 15:21 To: User discussion about the Rivendell Radio Automation System Subject: Re: [RDD] Rivendell GPIO with Kernel 3.2+ On Nov 19, 2012, at 20:34 32, Wayne Merricks wrote: > So heres the current error: > > In file included from /root/gpio-1.1.0/drv/gpio.c:30:0: > /root/gpio-1.1.0/drv/gpio.h:77:28: fatal error: linux/autoconf.h: No such > file or directory > compilation terminated. Lovely. Sounds like it's time to load up a 3.2.x kernel and get it sorted. Perhaps a project for the long weekend...
