Hi there,
The following rfc patch is to add lockdep support and IRQ-flags
state tracing support for ia64 architecture based on instructions
described in irqflags-tracing.
The next step is to fix issues. I plan to target it for -32 or -33.
Ps. Bob Picco had done similar things before.
Ps. The patch is enclosed in attachment. The inlined one
is c&p of it for reading.
Thanks,
Luming

Why was this seemingly unrelated change done in a lockdep patch?

The (shorter) form we generally use when architectures enable a
feature is:
config LOCKDEP_SUPPORT
def_bool y
config STACKTRACE_SUPPORT
def_bool y
( Separate cleanup patch: it might make sense to offer this in
generic code and just select a HAVE_LOCKDEP_SUPPORT flag. This
affects all lockdep architectures so should be handled
separately. )

also, these functions should be implemented, for lockdep reports to
be readable. Generally this is done by librarizing the dump_stack()

please use C inline functions for all of irqflags.h (x86 does that
too). Macros have all sorts of disadvantages: they are harder to
read and also double evaluation side-effects are harder to keep

That should be fixed (and this chunk will then not be needed) before
this is merged.
Also, a few general comments:
- There's no lockdep_sys_exit support implemented. (This callback
is needed to detect lock counts leaking to user-space. Just call
it in the return-from-syscall codepath(s).)
- There's no changes to exception code assembly AFAICS - such as
debug traps, special exceptions, etc. You should review all
places in the IA64 code where there's open-coded or
hardware-implicit enable-irqs or disable-irqs instructions, not
just the main local_irq_*() functions. A starting point would be:
git grep IA64_PSR_I arch/ia64/ | grep .S:
but there may be instructions and trap entries where there's
implicit irq-flags behavior - those need to be examined too.
- Do kprobes work with this patch?
- No NMI support AFAICS - all NMI codepaths should be exempted from
irqflags coverage.
Thanks,
Ingo

IIRC it is because the lockdep code needs a lot more percpu memory than the
64K that ia64 allocates.
But I think that I'd prefer to only allocate the extra space when it
is needed:
#ifdef CONFIG_LOCKDEP
#define PERCPU_PAGE_SHIFT 20 /* Need a Megabyte for lockdep */
#else
#define PERCPU_PAGE_SHIFT 16 /* 64K should be enough for normal use */
#endif

Hmm, isn't all that percpu stuff in a special section, who's size you
can query at boot time and set-up accordingly?

The size is a build time parameter (must match with a supported TLB page
size for ia64 ... i.e. even power of two ... so 64K, 256K, 1M, 4M are all
possible, but 128K, 512K, 2M, ... are not).
Any code that includes the right header files can look at PERCPU_PAGE_SHIFT
(or PERCPU_PAGE_SIZE) and make decisions about things. But in the
lockdep case the extra percpu space is statically allocated, so the special
section overflows and results in a build failure.

Good point. There are a lot of such kind of Macros in IA64

Without dynamic allocation both in Lockdep code and
ia64 architecture in place, 13 bits requires far moe
size than ia64 can support in Per CPU area (1M)

Updated in new patch. But Temporarily commented out in call site.
I tested it, but there is lock held before leaving kernel...
Will root cause, and fix the problem later.

Updated some in assembly code that modify PSR.I bit.
But not all, because not all modifications of PSR.i bit
would be interesting to lockdep code..

Good point, I need to find out place to insert

Not done yet.

Luming,
Can you send the config file that you used to test this.
I turned on a bunch of LOCKDEP related things, but I may have
stumbled into areas that aren't working yet because my kernel
didn't boot (or say anything on the console, even with early
serial uart console enabled).
I'd like to take this patch so we can fix it up with incremental
patches ... but I'd like a better idea of what works now and
what doesn't.
Thanks

yes, will send my config later when back to office.

Please also send your config to me, let me check
what could make that happen.

> please check out the attached config.
Your config fails for me too (same way, blank screen, nothing on
serial console).
Essentially I applied your patch to 2.6.32 (patch only gave a few
"offset" warnings). Kernel
builds ok, and boots on tiger (using tiger_defconfig).
When I turned on some LOCKDEP bits (see attached config) it fails.
Nothing on the
early uart console to say why. Screen just blanks right away.

Hmm, I changed the bad config a bit as below.
Nothing seems to be lockdep releated.
And the resutling 2.6.31 with LOCKDEP bits enabled still

But let me try more on other ia64 boxes that I can get access.
Stay tuned.

I might have reproduced the problem on a HP ia64 system
with -32 kernel as the following info. But -31 kernel with
lockdep code enabled just works. ....debugging...

ah, I seem to have found the change in -32 against -31 that causes the trouble.
Commenting out the change make -32 Lockdep kernel boot.
Tony, please let me know whether you can reproduce..
kernel/lockdep.c
static int save_trace(struct stack_trace *trace)
{
trace->nr_entries = 0;
trace->max_entries = MAX_STACK_TRACE_ENTRIES - nr_stack_trace_entries;
trace->entries = stack_trace + nr_stack_trace_entries;
trace->skip = 3;
save_stack_trace(trace);
#if 0

if (trace->entries[trace->nr_entries-1] == ULONG_MAX)

Yes. Commenting this out makes the system bootable for me.

This happens because ia64 save_stack_trace() is currently an empty stub, so it
doesn't set trace->nr_entries.
Options:
1) Add trace->nr_entries = 1; to ia64 stub.
2) Change the generic code to defend against an unexpected failure in
save_stack_trace()
if (trace->nr_entries > 0 &&
trace->entries[trace->nr_entries-1] == ULONG_MAX)
trace->nr_entries--;
3) Delete the code in the "daft"[1] architectures, and drop this hunk
from the generic code.

I'm thinking 2 and 3 together sound like a plan :-)
