could you try -rt16, does it work better?

-rt19 seems to work except that asm/io_apic.h fails to include 
asm/apicdef.h so MAX_IO_APICS is undefined.

-rt19 still does not boot for me with PREEMPT_DESKTOP and the latency
debugging options enabled (same .config I sent previously).  I get
endless screenfuls of "=============" on boot.  grep shows that these
most likely come from kernel/rt.c.

yeah - i can reproduce it with your .config. It goes away if i go from 
PREEMPT_DESKTOP to PREEMPT_RT. Investigating.

which was the last -rt kernel that worked fine for you in 
PREEMPT_DESKTOP mode?

It has been a long time, possibly months - I've mostly been using
PREEMPT_RT.  But now I am working on a soft RT project that for various
reasons would like to use the mainline kernel, and I've found it still
has some scheduling bumps up to 5-7ms and am trying to identify the
problem.

Would you like me to do a binary search?

OK, 2.6.13-rt12 has the same problem.  I'm trying
2.6.13-rc4-RT-V0.7.52-02 now which is the oldest thing I still have
around.

With 2.6.13-rc4-RT-V0.7.52-02 (the oldest version I still have around) I
still can't build that config, but it fails with:

  LD      .tmp_vmlinux1
net/built-in.o: In function `rt_check_expire':
route.c:(.text+0x1a66a): undefined reference to `__bad_spinlock_type'

make: *** [.tmp_vmlinux1] Error 1

AFAICT all the realtime-preempt patches have references to
__bad_spinlock_type but none of them ever define it - I can't figure out
what's going on.

I'll try to build something older.

thanks. I have further narrowed it down from this point: your .config 
breaks from the 51-01 to the 51-02 kernel (on my testbox).

ok, fixed this one, it was the CURRENT_PTR optimization on UP that broke 
if 4K stacks were enabled. (i disabled the optimization for now)

But interestingly, your .config unearthed 2 other serious bugs (!) as 
well: the spin_unlock_irq() upon printk was incorrect for !PREEMPT_RT, 
and there was an assert introduced by the get-rid-of-bitlocks ext3 
patches which was invalid on UP && !PREEMPT_RT. We had these bugs for 
quite some time.

I've released -rt21 with these fixes, does it work better for you?

Ingo,

We are unable to build a similar .config (PREEMPT_DESKTOP with soft and
hardirq preemption disabled) on x86-64:

In file included from include/linux/mm.h:15,
                 from kernel/printk.c:20:

include/linux/fs.h:849: warning: implicit declaration of function `down'
include/linux/fs.h: In function `unlock_super':

Let me know if you need the exact .config

Looks like Ingo has a generic rwsem to work with, but if your arch turns
on CONFIG_RWSEM_XCHGADD_ALGORITHM, it will compile lib/rwsem.c which
won't compile as you've seen.

Try out this patch:  I changed the Makefile, instead of going to each
and every arch and change its Kconfig to do it properly.

The patch had no effect.

In fact x86-64 does not set CONFIG_RWSEM_XCHGADD_ALGORITHM so this test
in include/linux/rwsem.h causes asm/rwsem.h to be included which does
not exist on x86-64:

36 #ifdef CONFIG_RWSEM_GENERIC_SPINLOCK
37 # include <linux/rwsem-spinlock.h> /* use a generic implementation */
38 #  ifndef CONFIG_PREEMPT_RT
39 #  define __RWSEM_INITIALIZER __COMPAT_RWSEM_INITIALIZER
40 #  define DECLARE_RWSEM COMPAT_DECLARE_RWSEM
41 # endif
42 #else
43 # include <asm/rwsem.h> /* use an arch-specific implementation */
44 #endif

If I change that code to always include <linux/rwsem-spinlock.h>, I get
the exact same failures I did with 2.6.14-rt22:

$ make

Yes I posted the .config earlier in the thread.  Let me know if you want

Yeah, could you send it to me privately.  I see a .config, but that was
for the 2.6.14-rt15 thread.

Send it to me and I'll try to compile it later tonight.

Yes it does. Sorry I hadn't responded yet. Thanks. Now just wish I could

Here Lee,

I got it to compile, but I haven't yet tried to boot it.  As a matter of
fact, I haven't booted any 2.6.15-rc5-rt1 on any of my machines.  I must
trust Ingo too much, since I started porting my kernel to his before
testing it to see if it works without my changes.  Oh well, I know what
to do tomorrow.

Well, this compiles, you can see if it boots ;-)

i rather went for fixing up the Kconfig, that makes things easier to 
follow. If it turns out to be lots of duplicate stuff we could create a 
lib/Kconfig.rwsem that architectures can include.

OK, scratch my last patch.  I'll submit this arch per arch.  Starting
with i386.  Each arch does it differently, so a generic lib/Konfig.rwsem
wouldn't work, since each arch has a different dependency.

-- Steve

Quick note:

I originally had:  default y if !(RWSEM_GENERIC_SPINLOCK || PREEMPT_RT || M386)
But then I realized that RWSEM_GENERIC_SPINLOCK was dependent on 
(PREEMPT_RT || M386) so I thought it was redundant to keep the three,
since RWSEM_GENERIC_SPINLOCK itself satisfies the dependencies.

I guess this may be the only patch needed so far.  x86_64 doesn't use a
RWSEM_XCHGADD_ALGORITHM, and as for the other archs:

alpha and ia64 - doesn't have PREEPMT_RT yet.

arm, cris, frv, h8300, m32r, parsic don't seem to implement the XCHGADD.

But I see that powerpc will need a fix, but I'll let others who actually
have the boards to fix them. ;-)

As for what I own: x86_64 and i386, the patches I sent are sufficient.

If anyone would like to give me a special board (to keep), I'll gladly
make sure that Ingo's -RT kernel runs on it.

The first chunk of this patch (removing dependency of
RWSEM_GENERIC_SPINLOCK on PREEMPT_RT) is still needed to build
2.6.15-rc5-rt2 on x86-64.  Not sure whether this boots yet.

2.6.15-rc5-rt1 compiles with the patch but does not boot.
