Donny9 opened a new pull request, #6685:
URL: https://github.com/apache/incubator-nuttx/pull/6685
## Summary
1. Output memory info about each task when malloc failed.
* I think outputting each task information directly is more useful than
dumping the entire heap, because it can be clear know who is occupying the most
memory blocks, who may leak, and if there is too much dump heap, it may trigger
wdt interrupt.
example:
2. change the type config MM_BACKTRACE from bool to int.
Initially, the entire backtrace function relied on DEBUG_MM, but due to the
conflict with memory-related log output control, it was replaced with a new
config MM_BACKTRACE.
* Therefore, this config will control the trace function, including pid
information and backtrace information, but some platforms have limited
resources, and these two information need to be controlled separately, so thid
PR will do this:
* when MM_BACKTRACE = -1, disable trace function
* when MM_BACKTRACE = 0, only enable pid information for trac function.
* when MM_BACKTRACE = 8, enbale entir trace function. 8 is the default
backtrace stack depth, if you need a larger depth, you need to update
MM_MIN_SHIFT in mm/mm_heap/mm.h synchronously.
