All of the Red-Black Tree _yielding functions have been
updated to work with reductions returned by the called
function instead of yielding on each element.

jhogberg/john/erts/mark-pooled-free-blocks-unused/OTP-15075
Mark free blocks in pooled carriers as unused
|
|
This lets the OS reclaim the physical memory associated with these
blocks which reduces the impact of long-lived awkward allocations.
A small allocated block will still keep a huge carrier alive, but
the unused part of the carrier will now be available to the OS.

* john/erts/adjust-fix-alloc-sizes:
Adjust fix_alloc sizes to guarantee they fit a dd block
|
|
This failed on 32-bit builds, and wasn't noticed because 32-bit
debug builds didn't run during the test period.
|
|
Remove check_limit_count
and just recalculate when needed,
that is when carriers are added/removed.
|
|
and avoid faulty bumps of 'entrance_removed' stat.

This commit replaces the old memory instrumentation with a new
implementation that scans carriers instead of wrapping
erts_alloc/erts_free. The old implementation could not extract
information without halting the emulator, had considerable runtime
overhead, and the memory maps it produced were noisy and lacked
critical information.
Since the new implementation walks through existing data structures
there's no longer a need to start the emulator with special flags to
get information about carrier utilization/fragmentation. Memory
fragmentation is also easier to diagnose as it's presented on a
per-carrier basis which eliminates the need to account for "holes"
between mmap segments.
To help track allocations, each allocation can now be tagged with
what it is and who allocated it at the cost of one extra word per
allocation. This is controlled on a per-allocator basis with the
+M<S>atags option, and is enabled by default for binary_alloc and
driver_alloc (which is also used by NIFs).

* Give back carrier to owner when put in pool with use of dd-queue.
* Replace pooled_list with pooled_tree for more efficient search
of all owned pooled carriers.
* Remove traitor_list as it does not serve much purpose anymore.
* Add HOMECOMING bit flag in crr->allctr atomic to
(1) avoid double enqueue into dd-enqueue.
(2) trigger read barrier in get_used_allctr for newly received carriers.
|
|
by adding a dedicated 'homecoming_dd_block' to use in dd-queue.
+ Preparation for dd-queue-migration of non-empty carriers.
+ Get rid of ugly hack where blk->carrier pointer is overwritten
by dd-queue and then have to be restored.

This refactor was done using the unifdef tool like this:
for file in $(find erts/ -name *.[ch]); do unifdef -t -f defile -o $file $file; done
where defile contained:
#define ERTS_SMP 1
#define USE_THREADS 1
#define DDLL_SMP 1
#define ERTS_HAVE_SMP_EMU 1
#define SMP 1
#define ERL_BITS_REENTRANT 1
#define ERTS_USE_ASYNC_READY_Q 1
#define FDBLOCK 1
#undef ERTS_POLL_NEED_ASYNC_INTERRUPT_SUPPORT
#define ERTS_POLL_ASYNC_INTERRUPT_SUPPORT 0

The implementation is still hidden behind ERTS_ENABLE_LOCK_COUNT, and
all categories are still enabled by default, but the actual counting can be
toggled at will.

Instead of passing around a file descriptor
use a function pointer to facilitate more advanced
backend write logic such as size limitation or compression.

For non-amd64 it's a "normal" allocator with a

The is similar to lost commit 31bc414dc9639ccf94f9011ed32
