Eric Andersen53601822002-12-05 21:12:42 +000065 There are 3 ways BusyBox can handle buffer allocations:
66 - Use malloc. This costs code size for the call to xmalloc.
67 - Put them on stack. For some very small machines with limited stack
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +000068 space, this can be deadly. For most folks, this works just fine.
Eric Andersen53601822002-12-05 21:12:42 +000069 - Put them in BSS. This works beautifully for computers with a real
70 MMU (and OS support), but wastes runtime RAM for uCLinux. This
71 behavior was the only one available for BusyBox versions 0.48 and
72 earlier.

594 If you want to build BusyBox with large file support, then enable
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000595 this option. This will have no effect if your kernel or your C
596 library lacks large file support for large files. Some of the
Denis Vlasenkof545be02007-10-07 17:06:26 +0000597 programs that can benefit from large file support include dd, gzip,
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000598 cp, mount, tar, and many others. If you want to access files larger
599 than 2 Gigabytes, enable this option. Otherwise, leave it set to 'N'.

689 dmalloc support:
690 ----------------
Eric Andersenc9f20d92002-12-05 08:41:41 +0000691 This enables compiling with dmalloc ( http://dmalloc.com/ )
692 which is an excellent public domain mem leak and malloc problem
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000693 detector. To enable dmalloc, before running busybox you will
Eric Andersenc9f20d92002-12-05 08:41:41 +0000694 want to properly set your environment, for example:
695 export DMALLOC_OPTIONS=debug=0x34f47d83,inter=100,log=logfile
696 The 'debug=' value is generated using the following command
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000697 dmalloc -p log-stats -p log-non-free -p log-bad-space \
698 -p log-elapsed-time -p check-fence -p check-heap \
699 -p check-lists -p check-blank -p check-funcs -p realloc-copy \

Eric Andersenf086ed82004-05-25 11:30:22 +0000702 Electric-fence support:
703 -----------------------
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000704 This enables compiling with Electric-fence support. Electric
Eric Andersen88c916b2003-10-22 09:58:56 +0000705 fence is another very useful malloc debugging library which uses
Eric Andersenc7bda1c2004-03-15 08:29:22 +0000706 your computer's virtual memory hardware to detect illegal memory
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000707 accesses. This support will make BusyBox be considerable larger
Eric Andersenc7bda1c2004-03-15 08:29:22 +0000708 and run slower, so you should leave this option disabled unless
Eric Andersenc9f20d92002-12-05 08:41:41 +0000709 you are hunting a hard to find memory problem.
