- If a trace entry has a stack trace, attempt to demangle the associated symbols.
Could be enhanced further to also demangle the arguments but doesn't yet.
Interestingly there are some mangled symbols that our demangler appears to
not handle correctly (gcc4).
* Introduce TracingMetaData::IsInBuffer() to validate that a certain memory
range is within the valid tracing buffer limits.
* Use that when validating in tracing_is_entry_valid() before trying to access
the entry, resolving a TODO.
* Validate the candidate time against the handed in time (if specified) as an
additional check.
* Tiny unrelated text cleanup.

return a stack trace when tracing is disabled we don't really need to be able
to print one either.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@43088 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Add TraceOutput::PrintArgs(), a va_list version of Print().
* Move code of TraceOutput::Print() to new private template function
print_stack_trace().
* Add public tracing_print_stack_trace().
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@43085 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Move struct tracing_stack_trace to tracing.h header.
* Add tracing_find_caller_in_stack_trace(). Helper function to get the
first return address of a stack trace that is not in one of the given
address ranges.
* Add AbstractTracingEntryWithStackTrace::StackTrace() getter.
* Add tracing_is_entry_valid(). Checks, based on the additionally given
time, whether a tracing entry is (probably) still in the tracing
buffer.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@43070 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Add an AbstractTraceEntryWithStackTrace that includes stack trace handling.
* Add a selector macro/template combo to conveniently select the right base
class depending on whether stack traces are enabled or not.
* Minor style cleanups.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@43045 a95241bf-73f2-0310-859d-f6bbb57e9c96
* The team and thread kernel structures have been renamed to Team and Thread
respectively and moved into the new BKernel namespace.
* Several (kernel add-on) sources have been converted from C to C++ since
private kernel headers are included that are no longer C compatible.
Changes after merging:
* Fixed gcc 2 build (warnings mainly in the scary firewire bus manager).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40196 a95241bf-73f2-0310-859d-f6bbb57e9c96
restrictions for virtual/physical addresses.
* vm_page_allocate_page_run():
- Fixed conversion of base/limit to array indexes. sPhysicalPageOffset was not
taken into account.
- Takes a physical_address_restrictions instead of base/limit and also
supports alignment and boundary restrictions, now.
* map_backing_store(), VM[User,Kernel]AddressSpace::InsertArea()/
ReserveAddressRange() take a virtual_address_restrictions parameter, now. They
also support an alignment independent from the range size.
* create_area_etc(), vm_create_anonymous_area(): Take
{virtual,physical}_address_restrictions parameters, now.
* Removed no longer needed B_PHYSICAL_BASE_ADDRESS.
* DMAResources:
- Fixed potential overflows of uint32 when initializing from device node
attributes.
- Fixed bounce buffer creation TODOs: By using create_area_etc() with the
new restrictions parameters we can directly support physical high address,
boundary, and alignment.

map_physical_memory()'s physicalAddress parameter type from void* to
phys_addr_t. This breaks source compatibility, but -- as long as
phys_{addr,size}_t remain 32 bit wide -- keeps binary compatibility with
BeOS.
* Adjusted all code using the affected interfaces (Oh what fun!). Added a few
TODOs in places where the wrong types (e.g. void* for physical addresses
are used). Looks like quite a few drivers aren't 64 bit safe and others
will break with PAE.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36960 a95241bf-73f2-0310-859d-f6bbb57e9c96
CREATE_AREA_DONT_WAIT flag; waiting at this point is not allowed.
* I hope I found all occurences, but there might be some areas left (note,
only those that don't use B_ALREADY_WIRED are problematic).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36624 a95241bf-73f2-0310-859d-f6bbb57e9c96
* More output.
* Actually increment errorCount when encountering an error. The loop
condition would never be false this way.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35750 a95241bf-73f2-0310-859d-f6bbb57e9c96
* When interrupts are disabled, it is still safe to capture the kernel stack
trace. The respective TODO preceded the introduction of the "kernelOnly"
flag.
* Actually made "kernelOnly" work. The wrong flag was passed to
arch_debug_get_stack_trace() in case it was false, so we never captured
user stack traces.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34832 a95241bf-73f2-0310-859d-f6bbb57e9c96
the function shall nevertheless return the length of the string that would
be written, if the buffer were large enough.
Added a touch of C++ while doing that. :-)
* Fixed the instances in boot loader, kernel, and kernel modules where the
wrong semantics were expected. The majority of uses actually.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34826 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Replaced the "userOnly" parameter by a "flags" parameter, that allows to
specify kernel and userland stack traces individually.
- x86, m68k: Don't always skip the first frame as that prevents the caller
from being able to record its own address.
* capture_tracing_stack_trace(): Replaced the "userOnly" parameter by
"kernelOnly", since one is probably always interested in the kernel stack
trace, but might not want the userland stack trace.
* Added stack trace support for VM cache kernel tracing.

code is no longer loaded, e.g. when the module has been unloaded or the tracing
buffer was reattached from a previous session.

tracing buffer entry list at least. Eventually we should check the entries
themselves, too.

tracing use before real initialization to be ignored gracefully again. Fixes
#4158.

Moved the static variables for managing the tracing buffer into a separate
area. The area is mapped at one of a few possible physical addresses and can
be found again when rebooting. This allows us to resurrect the tracing buffer
from the previous session, which could help tremendously when tracking certain
bugs (like triple faults). There's very little checking done yet, so it is
probably not as robust as we would wish it to be.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31942 a95241bf-73f2-0310-859d-f6bbb57e9c96
many iframes are supposed to be skipped before recording the stack
trace. Currently implemented for x86 only.

tracing buffer entries even when not in the kernel debugger.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27302 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fixed TraceEntryIterator::Current(): If fEntry was NULL, it would
return 0x4.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26955 a95241bf-73f2-0310-859d-f6bbb57e9c96
compatible with what our code assumed (pointers to objects of
TraceEntry and its POD base class trace_entry aren't identical
anymore).
* Added optional stack traces for ktrace_printf() output in the kernel.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25531 a95241bf-73f2-0310-859d-f6bbb57e9c96
modules could use it. Moved the tracing_stack_trace definition out of
the conditional section instead.
* Made the TraceOutput::Print()/PrintStackTrace() method no-ops when
tracing is disabled.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25211 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added capture_tracing_stack_trace() which allocates space in the
tracing buffer and captures the stack trace according to the given
parameters.
* Added TraceOutput::PrintStackTrace() to print a stack trace thus
created.
* Added TraceEntry::DumpStackTrace() callback which is supposed to print
a stack trace for the entry, if it can do that.
* Added "--stacktrace" switch to the "traced" command, which causes the
stack traces for all entries that have one to be printed as well.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25205 a95241bf-73f2-0310-859d-f6bbb57e9c96
kernel and added a WrapperTraceFilter* parameter, which allows for
additional filtering. This way other commands can print tracing output
with special filtering.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25094 a95241bf-73f2-0310-859d-f6bbb57e9c96
set the actual pattern as "%d", "%x", and "%s" of the expression
after '#' respectively. They are very slow, though.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24591 a95241bf-73f2-0310-859d-f6bbb57e9c96
TraceOutput for output options instead.
* Added "traced" option --difftime. Instead of the absolute system time
it prints the difference time to the previously printed entry.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23864 a95241bf-73f2-0310-859d-f6bbb57e9c96
printing the last 30 entries, it continues the last iteration, thus
making the more common use case more comfortable. The old functionality
is still available via "traced 0".

is recorded in a kernel trace entry (if tracing is enabled).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23686 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added "printteam" switch to "traced" command, enabling the printing of
the team ID.
* Added "team" filter to the "traced" command expression language.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23684 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made the iterator static, so that it's possible to move from the
iteration position of the previous invocation to the current start,
instead of always having to start from the beginning or the end.
* Filtered backward iteration:
- Restrict the range to dump to the entries between the first and the
last filter match.
- Use new FILTER_MATCH entry flag to avoid applying the filter a
second time in the print loop.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23681 a95241bf-73f2-0310-859d-f6bbb57e9c96
write code aligned to what one has written in the comment (or the
other way around).
* Made trace_entry structure doubly linked, by introducing a
previous_size member. By using bit fields, shrinking the flags field
to 4 bits, and not saving the lower two bits of size and previous_size
(which are always 0 due to alignment), the structure remains 4 byte
sized and can still address the same entry size.
* kBufferSize is no longer one less than it could be.
* "traced" command:
- Use static variable for the iteration state rather then cluttering
the temporary debug variable name space.
- The <count> parameter can now be negative, in which case the entries
before (and including) <start> are printed.
- Added a new optional parameter, specifying the maximal number of
entries to be filtered. Filtered iteration is beautifully
comfortable now.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23678 a95241bf-73f2-0310-859d-f6bbb57e9c96
disabled in most cases.
* Wrapping in make_space() was broken. When wrapping the second time or
later, sFirstEntry would already be greater than sAfterLastEntry and
resetting sAfterLastEntry to the beginning of the buffer would
erroneously "free" all entries between the buffer start and the
original sAfterLastEntry. If the tracing buffer was small enough,
the odds were that a not yet fully initialized entry would already
be re-allocated, causing all kinds of weird behavior.
* When an entry that is not yet fully initialized needs to be
freed, we let the allocation causing the freeing fail. We can't wait
for the entry, since we've interrupts disabled and since the entry
initialization might even try to allocate more (buffer) entries.
* make_space() is now safe to be called in any situation, and
allocate_entry() will do that, which simplifies things there and
avoids a few duplicate checks.
* Moved maximum allocation size check from alloc_tracing_buffer() to
allocate_entry(). Just in case... :-)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23662 a95241bf-73f2-0310-859d-f6bbb57e9c96
boolean operators ("not", "and", "or") and filters matching thread IDs
or contained strings.
I'm still not fully happy with the command. It should be possible to
define a filter and then comfortably scroll through the matching
entries. Currently having to specify an index range of the unfiltered
entries is rather unhandy in combination with filtering.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23658 a95241bf-73f2-0310-859d-f6bbb57e9c96
checks it now.
* Check for NULL pointer in alloc_tracing_buffer_strcpy(), and also
determine the length of userland strings before allocating the buffer
(using user_strlcpy()).
