Version History

|
---------------
|
|
-v2.4.4 (October 13 2008)
|
|
* Corrected minor syntactic bug on statistic gathering code.
|
|
Reported by Tim Cussins and P. Mantegazza.
|
|
|
|
-v2.4.3 (July 30 2008)
|
|
* Minor fixes to compile with the greenhills compiler.
|
|
Reported by "Kaya, Sinan SEA" <sinan.kaya@siemens.com>
|
|
* Small change in the license in order to include TLSF in the RTEMS
|
|
project.
|
|
|
|
-v2.4.2 (May 16 2008) (Herman ten Brugge)
|
|
* Memory usage statistics added again, with cleaner and more compacted
|
|
code.
|
|
|
|
-v2.4.1 (April 30 2008)
|
|
* Fixed a bug in the tlsf_realloc function: init the pool automatically
|
|
on the first call.
|
|
Reported by: Alejandro Mery <amery@geeks.cl>
|
|
|
|
-v2.4 (Feb 19 2008)
|
|
* "rtl_*" functions renamed to "tlsf_*".
|
|
* Added the add_new_area function to insert new memory areas to an
|
|
existing memory pool.
|
|
* A single TLSF pool can manage non-contiguous memory areas.
|
|
* Support for mmap and sbrk added.
|
|
* The init_memory_pool is not longer needed when used on a system
|
|
with mmap or sbrk.
|
|
* Removed the get_used_size counting.The same functionality can be
|
|
implemented outside the TLSF code.
|
|
|
|
-v2.3.2 (Sep 27 2007)
|
|
* Minor cosmetic code improvements.
|
|
|
|
-v2.3.1 (Jul 30 2007)
|
|
* Fixed some minor bugs in the version 2.3. Herman ten Brugge

|
|
|
|
-v2.3 (Jul 28 2007) Released a new version with all the contributions
|
|
received from Herman ten Brugge <hermantenbrugge@home.nl>
|
|
(This is his summary of changes in the TLSF's code):
|
|
* Add 64 bit support. It now runs on x86_64 and solaris64.
|
|
* I also tested this on vxworks/32 and solaris/32 and i386/32
|
|
processors.
|
|
* Remove assembly code. I could not measure any performance difference
|
|
on my core2 processor. This also makes the code more portable.
|
|
* Moved defines/typedefs from tlsf.h to tlsf.c
|
|
* Changed MIN_BLOCK_SIZE to sizeof (free_ptr_t) and BHDR_OVERHEAD to
|
|
(sizeof (bhdr_t) - MIN_BLOCK_SIZE). This does not change the fact
|
|
that the minumum size is still sizeof (bhdr_t).
|
|
* Changed all C++ comment style to C style. (// -> /* ... *./)
|
|
* Used ls_bit instead of ffs and ms_bit instead of fls. I did this to
|
|
avoid confusion with the standard ffs function which returns
|
|
different values.
|
|
* Created set_bit/clear_bit fuctions because they are not present
|
|
on x86_64.
|
|
* Added locking support + extra file target.h to show how to use it.
|
|
* Added get_used_size function
|
|
* Added rtl_realloc and rtl_calloc function
|
|
* Implemented realloc clever support.
|
|
* Added some test code in the example directory.
|
|
|
|
-- Thank you very much for your help Herman!

|
|
|
-v2.2.1 (Oct 23 2006)
|
|
* Support for ARMv5 implemented by Adam Scislowicz
|
|
<proteuskor@gmail.com>. Thank you for your contribution.
|
|
|
|
- v2.2.0 (Jun 30 2006) Miguel Masmano & Ismael Ripoll.
|
|
|
|
* Blocks smaller than 128 bytes are stored on a single
|
|
segregated list. The already existing bits maps and data
|
|
structures are used.
|
|
* Minor code speed-up improvements.
|
|
* Worst case response time both on malloc and free improved.
|
|
* External fragmantation also improved!.
|
|
* Segragared lists are AGAIN sorted by LIFO order. Version
|
|
2.1b was proven to be no better than 2.1.
|
|
|
|
- v2.1b: Allocation policy has been always a LIFO Good-Fit, that
|
|
is, between several free blocks in the same range, TLSF will
|
|
always allocate the most recently released. In this version of
|
|
TLSF, we have implemented a FIFO Good-Fit. However,
|
|
fragmentation doesn't seems to be altered so is it worth it?.
|
|
|
|
- v2.1: Realloc and calloc included again in TLSF 2.0.
|
|
|
|
- v2.0: In this version, TLSF has been programmed from scratch.
|
|
Now the allocator is provided as an unique file. Realloc and
|
|
calloc are not longer implemented.
|
|
|
|
|
|
- v1.4: Created the section "Version History". Studied real
|
|
behaviour of actual applications (regular applications tend
|
|
to require small memory blocks (less than 16 bytes) whereas
|
|
TLSF is optimised to be used with blocks larger than 16
|
|
bytes: Added special lists to deal with blocks smaller than
|
|
16 bytes.
|
|
|
|
|
|
- v1.3: Change of concept, now the main TLSF structure is created
|
|
inside of the beginning of the block instead of being an
|
|
static structure, allowing multiple TLSFs working at the
|
|
same time. Now, TLSF uses specific processor instructions to
|
|
deal with bitmaps. TLSF sanity functions added to find TLSF
|
|
overflows. The TLSF code will not be RTLinux-oriented any
|
|
more.
|
|
|
|
- v1.1 ... v1.2: Many little bugs fixed, code cleaned and splitted
|
|
in several files because of cosmetic requirements.
|
|
Starting from TLSF v1.1, MaRTE OS
|
|
(http://marte.unican.es) uses the TLSF allocator
|
|
as its default memory allocator.
|
|
|
|
- v0.1 ... v1.0: First implementations were created for testing and
|
|
research purposes. Basically TLSF is implemented to
|
|
be used by RTLinux-GPL (www.rtlinux-gpl.org), so
|
|
it is RTLinux-oriented.
