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 + <hermantenbrugge@home.nl> + + -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. |
