With unlock -> notify order the thread can be preempted by other thread,
for example one that wants to lock the very same lock. This would produce
incorrect ordering of lock release and acquire events.
There are two changes to the protocol:
- `QueueMessageLiteral*` were changed and what used to be addresses are now addresses+metadata
- Other messages now send `QueueMessage*Metadata` with added metadata.
This will later be used to store and transmit message sources, level, etc.
This value is not used for anything, it was just a number displayed in
the UI without much meaning to anyone.
Operations on the queue during early init may not work correctly, stopping
some programs from running past the calibration loop.
This PR does the following things:
- Allow to lock the highlighted thread using left mouse click or lane popup menu
- Add more descriptions for wait reasons in View::DecodeContextSwitchReason
- Stores the Wakeup CPU so that we may display it in the CPU data view
- `QueueThreadWakeup` now contains cpu and adjust info (currently unused). Fits in the padding, no struct size change.
- `QueueContextSwitch` now also contains thread priorities information (windows+linux) and CState (windows), but currently unused by the profiler. Fits in the padding, no struct size change.
- Fixes Linux `EventWakeup` which tries to remove PERF_SAMPLE_CALLCHAIN on the wrong member. Set the whole `perf_event_attr` explicitely instead.
- Fixes Windows ReadyThread event being dropped if triggered before the thread switches out (this is confirmed to be normal behaviour, probably due to thread being switched out but context switch actually happening later)
- Bumps tracy file version and protocol versions
This can be used to erase all allocations made within the named memory
pool. The usual use case would be for arena allocators, which allocate
by advancing a pointer and never have to free the memory. There is no
tracking of individual allocations and everything is freed frequently,
by reseting the pointer, for example once per frame.
Since this is used in special-purpose allocators, there is no support
for discarding the memory of the default memory pool.
The windows.h header file defines the macro max. If the max macro is include
it will lead to name collisions with the std::numeric_limits<T>::max() function.
One solution is to define NOMINMAX before the inclusion of windows.h.
However, that might be a demanding task for a large codebase. Defining the
NOMINMAX as global define may also break previous code.
Another to solution to the problem is to wrap the numeric_limits function in
parenthesis to instruct the compiler to treat it as a function and not a macro.
This commit wraps the std::numeric_limits<T>::max() calls in the public
interfacing header files, with parenthesis.
