mod_timer_pinned will be dropped from linux kernel v4.8

[manjaro_oberon]

The Linux kernel is about to drop function mod_timer_pinned See:

​http://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/commit/?id=177ec0a0a531695210b277d734b2f92ee5796303

This change has meanwhile already been adopted by realtime patch rt8, resulting in vbox modules being un-available for this patched kernel. The function will be ultimately dropped from kernel series 48.

Current situation in vbox is this:

$ grep -re "mod_timer_pinned"

src/VBox/Runtime/r0drv/linux/timer-r0drv-linux.c:# define mod_timer_pinned mod_timer
src/VBox/Runtime/r0drv/linux/timer-r0drv-linux.c: mod_timer_pinned(&pSubTimer->u.Std.LnxTimer, pSubTimer->u.Std.ulNextJiffies);
src/VBox/Runtime/r0drv/linux/timer-r0drv-linux.c: mod_timer_pinned(&pSubTimer->u.Std.LnxTimer, pSubTimer->u.Std.ulNextJiffies);
src/VBox/Runtime/r0drv/linux/timer-r0drv-linux.c: mod_timer_pinned(&pSubTimer->u.Std.LnxTimer, pSubTimer->u.Std.ulNextJiffies);

I was not clear about the rt patch: This concerns rt kernels from 4.6.4-rt8 and newer.

patch for mod_timer_pinned kernel 4.8.x

I added a small patch solves my problem in the kernel 4.8.0-rc1 64bit

Thanks! A slightly better fix can be found in r63341.

Thanks a lot! We've added an extra define now in our rt-patched kernel and extended your patch to test additionally:

# if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 8, 0) || defined(RT_PATCHED)

and the extramodules are now building fine for all our kernels.

Replying to frank:

Correction, it is in VirtualBox-5.1.4.tar.bz2 , so this ticket could be closed , sorry for my previous mistake, I should had revert the patch for testing and forgot it.

Thanks.

I have still the same issue reported in the 'duplicate' Ticket #15713 guest additions do not build with 4.8 kernel:

vboxadd.sh: failed: Look at /var/log/vboxadd-install.log to find out what went wrong.
vboxadd.sh: failed: Please check that you have gcc, make, the header files for your Linux kernel and possibly perl installed.

I am using the latest VirtualBox Version (5.1.6 r110634) on a Windows 7 Host running the lates SLES12 Version (SLE-12-SP1-Server-DVD-x86_64-GM). What am I doing wrong?

BTW: the bidirectional usage of the clipboard doesn't work neither - is there a correlation?

Did you actually read the message which you posted? I would expect at least that you attach the /var/log/vboxadd-install.log file to this ticket...
