I previously split the global trace-events file up into one file
per-subdirectory to avoid merge conflict hell.
This series builds on that to now actually generate the individual
trace files per-subdirectory too. The key benefit of doing this is
that a change in a trace-events file will no longer cause a rebuild
of the entire world. Instead only that one affected sub-directory
will have files rebuilt.
The key problem faced when creating this patch series was the fact
that the trace code had a global assumption that there was a single
enum declaring all events in a sequence with no gaps. Most of the
hard work in this series involves getting rid of that assumption
throughout the code. Instead we now have a notion of trace event
groups, each with their own distinct enum of events. As such the
individual event IDs are no longer globally unique. Most of the
code could be adapted to work with IDs that were unique only within
a group.
The first sticky part was the simpletrace binary event format which
includes the event ID. To deal with this I invented a notion of an
ID offset per trace-events file. So simpletrace format will now
use "(id-offset << 16) | event-id" in order to get a globally
unique ID value for its trace files. This means each trace-events
file can only have 65536 distinct events declared, but that ought
to be enough for a while :-)
The second sticky part was the per-VCPU events, due to the use of
a "trace_dstate" bitmap in the CPUState struct. The bitmap
inherantly assumes a global ID sequence, and would not work well
with the per-file id-offset concept, since it would require a
huge mostly-sparse bitmap. Rather than try to solve this problem
I took the easy way out and simply specified that all per-VCPU
events need to be declared in the top level trace-events file.
Since we have almost no per-vCPU events today, this works out
just fine.
I've build-tested with all targets enabled in both VPATH and
non-VPATH setups, on Fedora 24, with all 5 trace event backends
enabled at once. I've tested that simpletrace.py can still
extract events from generated traces. I've not functionally
tested dtrace/ftrace/ust at this time.

Currently methods which want to iterate over trace events,
do so using the trace_event_count() and trace_event_id()
methods. This leaks the concept of a single ID enum to
the callers. There is an alternative trace_event_pattern()
method which can be used in an iteration context, but its
design is stateless, so is not easy to expand it in the
future.
This defines a formal iterator API will provide an future
proof way of iterating over events.
The iterator is also able to apply a pattern match filter
to events, further removing the need for the pattern

and some internal trace control methods to use the new
trace event iterator APIs.

The trace_event_count, trace_event_id and
trace_event_pattern methods are no longer required
now that everything is using the iterator APIs
The trace_event_set_state and trace_event_set_vcpu_state
macros were also unused.

Remove the notion of there being a single global array
of trace events, by introducing a method for registering
groups of events. The ID values will only be required to
be unique within the scope of a group of events.

The CPUState struct has a bitmap tracking which VCPU
events are currently active. This is indexed based on
the event ID values, and sized according the maximum
TraceEventVCPUID enum value. Since there will the
possibility of having multiple event groups, the
indexes will potentially overlap.
Rather than creating a more complex 2 dimensional
data structure in CPUState, make an assumption that
all the per-VCPU events will be defined in the same
event group. Do a sanity check for this assumption
when registering event groups.
In addition, rather than using the TRACE_VCPU_EVENT_COUNT
constant, which requires pulling in the enourmous trace
events header, define a fixed bitmap size, which allows
for 32 events. This will suffice for the immediate future
and can be easily raised later if needed.
With this change, the cpu.h file no longer has a direct
dependancy on the generate events header file.

There are currently two global event state arrays,
'uint16 dstate[]' and 'bool dstate_init[]' whose
sized is defined based on the TRACE_EVENT_COUNT
enum value.
When multiple event groups are enabled, it won't
be possible to used a fixed global event state.
This change thus expands the event group register
method so that the event state arrays can be passed
in when the group is registered.
When calling the methods for setting/getting the
trace event state, the caller also needs to pass
in the corresponding 'dstate' array. While it
would be possible to look up the array in the
group list, these methods are in the hot-path,
so passing in the array directly is hugely more
efficient. The extra parameter is no real burden
on callers, since all the code is auto-generated,
with the exception of a call in hw/usb/hcd-ohci.c

From: Daniel P. Berrange @ 2016-08-09 15:31 UTC (permalink / raw)
To: qemu-devel; +Cc: Stefan Hajnoczi, Daniel P. Berrange
Since there will shortly be multiple event groups allowed,
we can no longer use the TraceEventID and TraceEventVCPUID
enums in the trace control APIs. There will in fact be
multiple distinct enums, and the enum values will only be
required to be unique per group.

The TraceEvent struct vcpu_id field uses the constant
TRACE_VCPU_EVENT_COUNT as a magic value to indicate this
is not a per-VCPU event. The max count value will be
different for each event group though, so this is no
longer suitable. Instead use the value (size_t)-1 which
is guaranteed to be available across all event groups.

Now that none of the public APIs rely on the TraceEventID
enum, or related constants, it is possible to simplify
the includes, dropping generated-events.h from many of
them.

Currently the generated-events.[ch] files contain the
event enums, constants and TraceEvent arrays, while the
generated-tracers.[ch] files contain the actual trace
probe logic. With the decoupling of the event enums from
the API there is no longer any compelling reason for the
separation between these files. The enums/constants will
only ever be needed from the generated-tracers.[ch] files.
The enums/constants/structs from generated-events.[ch] are
thus moved into the generated-tracers.[ch], so that there
is one less file to be generated.

The declarations in the generated-tracers.h file are
assuming there's only ever going to be one instance
of this header, as they are not namespaced. When we
have one header per event group, if a single source
file needs to include multiple sets of trace events,
the symbols will all clash.
This change thus introduces a '--group NAME' arg to the
'tracetool' program. This will cause all the symbols in
the generated header files to be given a unique namespace.
If no group is given, the group name 'common' is used,
which is suitable for the current usage where there is
only one global trace-events file used for code generation.

From: Daniel P. Berrange @ 2016-08-09 15:31 UTC (permalink / raw)
To: qemu-devel; +Cc: Stefan Hajnoczi, Daniel P. Berrange
For simpletrace we need to be able to form a globally
unique ID value for trace records. Since the individual
events no longer have globally unique ID values, we
define an event ID offset per trace-events file.
The simpletrace records will now use
(id_offset << 16) | event_id
for the ID value in trace records.
Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

Yes it should be actually - left over from before I was using the
qemu-module support to register these.

Perhaps "unsigned" is a better match than size_t?

I don't mind either way - I just happen to personally always use size_t
for anything that ends up being used primarily as an array index.

Makes sense. I was thinking of simpletrace's 32-bit id instead.

Can we get this report to include details of the
a) the software versions of gcc, binutils, and any -devel packages
we're building against
b) the exact arguments + env variables used to invoke configure,
not merely its output
so we don't have to go digging into the docker test systemm to
try and reverse engineer this info

The whole point of docker test system is offer a relatively easy reproducer to
developers, so I'm reluctant to engineer patchew or the test script it runs for
that.
On the other hand, it's reasonable to allow the docker testing code to be more
verbose than currently. Or maybe we can patch ./configure to output these
information?

Actually, digging this info is pretty easy if you already use docker test
locally (if you don't, may I ask why?). Just append DEBUG=1 and you can mess
with things in the building env. Something like this
$ make docker-test-quick@centos6 DEBUG=1
Then you'll be dropped in the shell that is all set up to run the build command.

That's just pointlessly creating extra work for the developers reading
these build reports. If you outputted the info I suggest, it can help
developers diagnose the problems more quickly. Even if running the
docker env locally is possible & even easy, it doesn't make it faster
than reading the relevant info from email report in front of you.

Daniel

I agree with your point, I just don't know how to do a) neatly, except for a
vast change to configure.

Why do you need todo it in configure ? I was thinking your docker receipe
that invokes configure could just do it - not least because the commands to
run to get the data will be different based on which distro you're running
in the docker image in question.

Then the script needs to be updated to work with different package management
systems (rpm and deb). For now they only call standard Linux commands. That's
least of the problem, though.
The more tricky question is how the script can tell which packages are relevant
(or, used). I assume the number of packages in a docker image is quite limited
(fedora has 396, ubuntu 574), but dumping the whole list is still noisy
nevertheless. Also, depending on the configure option, a submodule can be used
instead, or a local built library. Not that we have a lot of these now, but
it's a factor of complication.
On the other hand, configure knows when to use pkg-config --modversion, or git
describe, or something else, depending on how and where it discovers the
compiler and -devel libs etc..

In the tests/docker/dockerfiles/*.docker files you install a bunch of
RPMs we build against. I was just thinking to report versions of those
particular RPMs.
IIt would be sufficient if you just captured the output of the
'dnf install' command (or equivalent) to, say /tmp/installed.txt.
Then have build_qemu() in common.rc simply cat /tmp/installed.txt
before running configure. That way all the distro-specific bits
stay in the *.docker files.

Daniel

I'd rather keep them as 'trace_events_dstate' and 'trace_events_dstate_init' if
most references are auto-generated. Or maybe I just missed something.
Also, maybe we should just try to get rid of the dstate_init structure. Only
vcpu events need late initialization, which could be something like:
trace_events_enabled_count--;
dstate[ev->id]--;
trace_event_set_state_dynamic(dstate, ev, true);
Non-vcpu events shouldn't need late initialization.

Should not be empty (here, stub means it's not target code).

I'd rather keep the "generated-" prefix on all files that usually are not
directly included by QEMU developers.

Can we get rid of the "@id_offset(NN)"? If we're generating a trace-events-all
all the same, we can use that to generate all the per-directory file *and* still
keep the simpler flat event ids.
For example, first we concatenate /trace-events, /io/trace-events and
/hw/usb/trace-events into /trace-events-all to produce:
@group core
@dir /
# contents of /trace-events
@group io
@dir /io
# contents of /io/trace-events
@group hw_usb
@dir /hw/usb
# contents of /hw/usb/trace-events
Then we can use /trace-events-all to generate all the per-directory trace.h
files while ensuring a perfectly flat event identifier space (a single
generated-events.c is used).
This should minimize changes to tracing code and avoid further restrictions
(like the "top-level vcpu" one).
Cheers,
Lluis

I'd rather not try to refactor that logic at the same time - it could
be done as a later patch, or if you want to submit a patch to fix that
I can rebase on top of it.

I don't think that's really needed - all these files are in sub-dirs
now and its a clear rule that trace*.[hc] is auto-generated in every
sub-dir now. Also no oither code in QEMU thats auto-generated adds
this prefix on so trace is inconsistent with practice elsewhere.

Daniel

One thing that occurred to me is that we could take a hash of the
group name. Since we have few enough sub-dirs / groups, and a large
enough ID space, it ought to be possible to get a hash which is
unique. The trace tool can double check that all groups get a unique
hash

That means when any individual trace file is changed, we re-generate the
world, which is exactly what this series is designed to avoid.

Absolutely yes, especially if you have build for multiple targets
enabled. Rebuilding all files when you have all 30+ targets enabled
takes an incredibly long time.

Can you include a description of how to reproduce with "make

Eliminating "@id_offset" is nice, but I would prefer to eliminate the event
hierarchy too.

Nope. We re-generate /trace-events-all, but each individual file generated
afterwards (taken from the "@dir" directive) will change only if its new
contents do (the Makefile uses cmp to check if files need updating from their
corresponding timestamp file).

I saw them later, sorry. But I still think these too should be renamed, to make
it clear it's related to tracing.

Having the event groups is the only way to avoid re-numbering all events
when a new one is added.

The contents will still need to change too if we have a global numbering
space as your suggestion requires. The event groups are the only way to
avoid that.

Shouldn't ev be updated inside the while loop? Otherwise the iterator
always returns &trace_events[0] the first time it's called.
A doc comment would help clarify the intended semantics of
trace_event_iter_next().

Hard-coding this is awkward. Can it be generated by tracetool at build
time so the bitmap is always large enough without manually bumping this
definition?

I think unsigned is slightly clearer since it expresses the intent that
the values are limited to 32 bits.

Nevertheless, I agree that @id_offset() should be eliminated to avoid
collisions and manual effort when trace-events files are added.

Sorry, I could not find the message where the infrastructure is modified to
provide this. But I think there's a more efficient way to provide modular
auto-generated tracing code without the hierarchical indexing you proposed.
What about using global variables? Instead of the dstate array, each event could
have this on the "public" header:
/* define for static state */
#define TRACE_EVENTNAME_ENABLED 1
/* pointer to event descriptor */
extern TraceEvent *TRACE_EVENTNAME;
/* variable with dynamic state */
extern bool ___TRACE_EVENTNAME_DSTATE;
void trace_eventname(...) {
if (trace_event_get_stateTRACE_EVENTNAME_ENABLED && ___trace_eventname_dstate) {
/* ... */
}
}
The use of event IDs on generic code can be adapted like this:
#define trace_event_get_state_dynamic_by_id(id) \
(unlikely(trace_events_enabled_count) && \
(___ ## id ## _DSTATE))
And then we can concatenate all "trace-events" files to generate the .c files:
struct TraceEvent {
/* ... */
bool *dstate;
};
bool ___TRACE_EVENTNAME_DSTATE;
struct TraceEvent ___trace_events[] = {
{
.name = "eventname",
.sstate = 1,
.dstate = ___trace_eventname_dstate;
}
}
TraceEvent *TRACE_EVENTNAME = &___trace_events[...];
So updating a single "trace-events" file does not force a recompile of the whole
QEMU, but we retain the performance of the flat dstate array (now a per-event
pointer) and the simpler flat structure for iteration based on event names.
Cheers,
Lluis

Life would be simpler if we had the 'bool dstate' as part of the
TraceEvent struct, but doing so would essentially be reverting this
previous change:
commit 585ec7273e6fdab902b2128bc6c2a8136aafef04
Author: Paolo Bonzini <pbonzini@redhat.com>
Date: Wed Oct 28 07:06:27 2015 +0100
trace: track enabled events in a separate array
This is more cache friendly on the fast path, where we already have
the event id available.
I asked Paolo about this previously and he indicated it was a notable
performance improvement, so we can't put dstate back into the TraceEvent
struct :-(
Regards,
Daniel

Is it worth updating the commit messages to commit ids that caused that
need for 1-4 in your series?

Sorry, there was a typo in my example code that led to this misunderstanding.
I meant this for the global auto-generated .c:
struct TraceEvent {
/* ... */
bool *dstate;
};
bool ___TRACE_EVENTNAME_DSTATE;
struct TraceEvent ___trace_events[] = {
{
.name = "eventname",
.sstate = 1,
.dstate = &___TRACE_EVENTNAME_DSTATE;
}
}
TraceEvent *TRACE_EVENTNAME = &___trace_events[...];
If you look at the modified macro I pasted for "trace/control-internal.h":
#define trace_event_get_state_dynamic_by_id(id) \
(unlikely(trace_events_enabled_count) && \
(___ ## id ## _DSTATE))
We're retaining the fast-path performance of the seggregated boolean dstate
array, while the event descriptor contains a pointer to the per-event dstate
global boolean variable in case you want to get/set the dstate based on an event
pointer.
Cheers,
Lluis

The various _DSTATE variables are still arbitrarily scattered in
memory, as opposed to in a contiguous cache friendly array, which
is one of the goals of Paolo's original change.
That said, I'm unclear on how much of the performance win from
Paolo's change came from eliminating the struct field de-reference,
vs having the contiguous array. I'm guessing most of the win is
from the former, the latter only being important if we hit multiple
related tracepoints on close succession.

Daniel

The latter can also be achieved by packing them all together in a single
section, but I don't know if that's acceptable within portable QEMU code. For
example:
bool ___TRACE_EVENTNAME_DSTATE __attribute__((section("dstate_array")))

Sorry, been focused on other series, but will try and post an update this
week considering the feedback.

I can help in implementing the global variable approach I described, if you
want.

Thanks for the offer, but the series is hairy enough to rebase that trying
to split the work will just create even more rebase pain than there already
is.

NB, the simpletrace backend requires a globally unique 32-bit integer ID
to be assigned to each trace event, so even with the approach you suggest
below we still need to be able to assign a global ID for each event.
So while your suggest below avoids having to pass around the dstate
arrays, which is nice, we still have to assign event id offsets to
each trace-event file in some manner TBD.

Acutally, it should be sufficient if we just generate all the dstate
variables in one place in the .c file - the compiler isn't going to
scatter a set of variables declared one after each other.

Corect me if I'm wrong, but if we only require these consecutive IDs for
simpletrace, they don't need to be visible to the tracing headers (these IDs are
only used in "trace/generated-tracers.c"). Therefore, we can get them from the
trace-events-all file, and minimize the complexity of the changes to tracetool.

The IDs need to be present in the generated tracers files which are split
up.

I'll switch to 'uint32_t' since that unambigously matches that
simpletrace mandates.

I think I have a workable solution to eliminate this. During build I'll
create a file 'trace-event-file-list' which contains a list of paths to
'trace-event' files in the tree. We'll then use the line number in this
file as the id offset for events. The generated $SUBDIR/trace.h file
will depend on trace-event-file-list.
So we'll have fully automatic numbering for each trace-event file and
will only get a full rebuild if someone adds a completely new trace-event
file, which is acceptable.
Regards,
Daniel

I'm not sure if I'm just missing what you mean.
Changing any of the trace-events files will trigger a recompilation of the .c
files specific to the simpletrace backend, but won't trigger a recompile of all
QEMU files including any of the tracing headers (just the files including the
"trace.h" corresponding to the modified "trace-events").
