Hello.
 
Is it really finished?
I have problems to compile the patched kernel.
 
At first, when it compiles machine.c, there is such error:
  CC      arch/x86/xenomai/machine.o
In file included from ./include/asm-generic/xenomai/syscall.h:23:0,
                 from arch/x86/xenomai/include/asm/xenomai/syscall.h:24,
                 from arch/x86/xenomai/machine.c:22:
./arch/x86/include/asm/uaccess.h: In function ‘set_fs’:
./arch/x86/include/asm/uaccess.h:33:9: error: dereferencing pointer to incomplete type ‘struct task_struct’
  current->thread.addr_limit = fs;
         ^~
 
After an ad-hoc fix, there are some other errors for example during compiling of thread.c, mostly connected to fpu:
fpu.fpregs_active, fpu.active_state, __fpregs_deactivate(), __fpregs_activate(), clts(), stts(), SLAB_NOTRACK, ...
 
Am I doing something wrong?
 
Best regards
Petr

You are likely not using the proper Xenomai branch, you need -next.

I would not suggest next, master and stable/v3.0.x should do. But
v3.0.7 and older will not work.

As far as i understood we will soon have a v3.1, for people that like
their releases ;).

"next" is now a (potentially rebasing) integration branch for "master". The 
latter will only evolve linearly, no more rebasing. Unless there is particular 
interest in some fix, "master" is indeed the recommendation for following the 
development for the next major release. Otherwise: stable.

I'm also planning to do a 3.0.8 release "soonish", specifically now that we have 
x86-ipipe updates that require this.

You are right.
The errors were because of version 3.0.7. I didn't realize, that prepare-kernel.sh script doesn't only apply the patch. But it also copies part of the xenomai to the kernel.
 
Meanwhile I tried the latest git (probably master branch). I got another error (simple to fix) in one of the rtnet drivers:
drivers/xenomai/net/drivers/e1000e/netdev.c: In function ‘e1000e_set_interrupt_capability’:
drivers/xenomai/net/drivers/e1000e/netdev.c:1225:11: error: implicit declaration of function ‘pci_enable_msix’; did you mean ‘pci_enable_msi’? [-Werror=implicit-function-declaration]
     err = pci_enable_msix(adapter->pdev,
           ^~~~~~~~~~~~~~~
           pci_enable_msi

Known issue: There is now pci_alloc_irq_vectors only. We need to switch to that 
API and provide backward compatible wrappers for < 4.8. If you do not need this 
driver, disable it for now.

[rtnet] e1000e/netdev.c deprecated pci_enable_msix

[alessio margan]

Hi all,

when compile the kernel linux-4.14.89-xeno-next I got this error, and I 
need to use the e1000e driver.

I come from a 4.9.51-xeno-3.0.6 and I would like to update xenomai with 
the last changes

For the moment I just comment the call to pci_enable_msix, there are any 
progress for the API switch ?

TIA

Alessio
