The first patch is just a lockdep clean up of the ring buffer.
The next patch is a new locking design. It is not lockless (yet) but
the locking is a bit cleaner than the original. The basic idea is
that the reader now has its own page to read from that is not in
the ring buffer. When the reader (a consumer) finishes a page, it
then grabs a lock to pull out a new page from the ring buffer and
replace it with the one that it just finished reading.
The writer only locks when it needs to go to the next page. We still
disable interrupts, but it would not be too hard to allow
interrupts to take place on writes. But I will leave that for
version 2 (or 1.2)
The iterator (non consuming read) still expects the tracer to
be disabled when iterating the loop (no locks taken).
The ring_buffer_{un}lock is now no longer around and not needed.
I ran this with lockdep on and it ran fine.
I did lots of testing of trace_pipe (consuming reader) while running
the function trace. The function trace with out a doubt will stress
the consumer/producer reads since the producer is much faster than the
consumer.
Tomorrow, I'll change the buffer_page from being a page_frame to
something that is allocated separately.

You should be able to reproduce it, it happens on every bootup with this config.

This patch does a new design to be partially lockless on writes. Writes will add new entries to the per cpu pages by simply disabling interrupts. When a write needs to go to another page than it will grab the lock. A new "read page" has been added so that the reader can pull out a page from the ring buffer to read without worrying about the writer writing over it. This allows us to not take the lock for all reads. The lock is now only taken when a read needs to go to a new page. This is far from lockless, and interrupts still need to be disabled, but it is a step towards a more lockless solution, and it also solves a lot of the issues that were noticed by the first conversion of ftrace to the ring buffers. Note: the ring_buffer_{un}lock API has been removed.

A robust tracer almost never wants to impose heavy locking semantics - a good way to disable/enable it on a per CPU basis is more than enough to 'freeze' the trace and get it out to the user. Perhaps, before we free trace buffers, we should do an RCU sync to make sure no access can linger? Right now we dont seem to free buffers anywhere.

* [PATCH] ftrace: preempt disable over interrupt disable 2008-10-01 7:23 ` Ingo Molnar 2008-10-01 12:32 ` Frédéric Weisbecker @ 2008-10-01 17:14 ` Steven Rostedt 1 sibling, 0 replies; 12+ messages in thread From: Steven Rostedt @ 2008-10-01 17:14 UTC (permalink / raw) To: Ingo Molnar Cc: Frédéric Weisbecker, linux-kernel, Thomas Gleixner, Peter Zijlstra, Andrew Morton, Linus Torvalds, Mathieu Desnoyers, Pekka Paalanen, Martin Bligh With the new ring buffer infrastructure in ftrace, I'm trying to make ftrace a little more light weight. This patch converts a lot of the local_irq_save/restore into preempt_disable/enable. The original preempt count in a lot of cases has to be sent in as a parameter so that it can be recorded correctly. Some places were recording it incorrectly before anyway. This is also laying the ground work to make ftrace a little bit more reentrant, and remove all locking. The function tracers must still protect from reentrancy. Note: All the function tracers must be careful when using preempt_disable. It must do the following: resched = need_resched(); preempt_disable_notrace(); [...] if (resched) preempt_enable_no_resched_notrace(); else preempt_enable_notrace(); The reason is that if this function traces schedule() itself, the preempt_enable_notrace() will cause a schedule, which will lead us into a recursive failure. If we needed to reschedule before calling preempt_disable, we should have already scheduled. Since we did not, this is most likely that we should not and are probably inside a schedule function. If resched was not set, we still need to catch the need resched flag being set when preemption was off and the if case at the end will catch that for us.
