9e37d70163 Create mem_mutext at the end of mem_init. This enables sys_mutex_new to use the heap if required. 2010-03-07 16:50:08 +00:00

0030d1ade5 task #10139 (Prefer statically allocated memory): converted mbox and semaphore functions to take pointers to sys_mbox_t/sys_sem_t; converted sys_mbox_new/sys_sem_new to take pointers and return err_t; task #7212: Add Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX to let sys.h use binary semaphores instead of mutexes - as before) 2010-02-12 13:49:21 +00:00

8596bb7e7e The heap now may be moved to user-defined memory by defining LWIP_RAM_HEAP_POINTER as a void pointer to that memory's address (patch #6966 and bug #26133) 2010-01-13 13:09:55 +00:00

cbfacb7ed9 bug #26213 "Problem with memory allocation when debugging": memp_sizes contained the wrong sizes (including sanity regions); memp pools for MEM_USE_POOLS were too small; Added option MEM_USE_POOLS_TRY_BIGGER_POOL to try the next bigger malloc pool if one is empty (only usable with MEM_USE_POOLS). 2009-04-25 17:42:27 +00:00

13d8ae859d fixed bug #21433: Calling mem_free/pbuf_free from interrupt context isn't safe: LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT allows mem_free to run between mem_malloc iterations. Added illegal counter for mem stats. 2008-06-30 18:16:51 +00:00
goldsimon
779938ea68 patch #6483: stats module improvement: Added defines to display each module's statistic individually, added stats defines for MEM, MEMP and SYS modules, removed (unused) rexmit counter. 2008-06-27 18:37:53 +00:00
goldsimon
43dd38df0a fixed bug #21433 (Calling mem_free/pbuf_free from interrupt context isn't safe): set LWIP_USE_HEAP_FROM_INTERRUPT to 1 in lwipopts.h or use tcpip_callback_nonblocking(pbuf_free_int, p)/ tcpip_callback_nonblocking(mem_free, m) to free pbufs or heap memory from interrupt context 2008-03-27 19:29:35 +00:00

6e612e5def mem_malloc with MEM_USE_POOLS=1: if size > size of biggest pool and custom pools (in addition to the MEM_POOLs) were defined, the first custom pool was used instead of asserting 2007-11-28 18:24:08 +00:00

199648ff37 Changed initialization: many init functions are not needed any more since we now rely on the compiler initializing global and static variables to zero! 2007-10-09 19:59:56 +00:00

e3cd1ac1f9 Minor changes (but in lot of files): add #if/#endif for options where they could miss. #if LWIP_xxx if always put after #include "lwip/opt.h" (note this one indirectly include cc.h). Move others includes inside #if/#endif block. 2007-09-07 23:01:59 +00:00

0c18e653e8 Introduced the option MEM_USE_POOLS to use 4 pools with different sized elements instead of a heap. This both prevents memory fragmentation and gives a higher speed at the cost of more memory consumption. Turned off by default. 2007-06-21 20:12:11 +00:00

bdbc96f453 opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid some macro names collision with some OS macros. 2007-06-13 17:17:26 +00:00
