A kernel -thread scans the memory every 10 minutes (by default) and prints any new -unreferenced objects found.

The following parameters are supported: - - off - disable kmemleak (irreversible) - stack=on - enable the task stacks scanning - stack=off - disable the tasks stacks scanning - scan=on - start the automatic memory scanning thread - scan=off - stop the automatic memory scanning thread - scan= - set the automatic memory scanning period in seconds (0 - to disable it) - -Kmemleak can also be disabled at boot-time by passing "kmemleak=off" on -the kernel command line. - -Basic Algorithm ---------------- - -The memory allocations via kmalloc, vmalloc, kmem_cache_alloc and -friends are traced and the pointers, together with additional -information like size and stack trace, are stored in a prio search tree. -The corresponding freeing function calls are tracked and the pointers -removed from the kmemleak data structures. - -An allocated block of memory is considered orphan if no pointer to its -start address or to any location inside the block can be found by -scanning the memory (including saved registers). This means that there -might be no way for the kernel to pass the address of the allocated -block to a freeing function and therefore the block is considered a -memory leak. - -The scanning algorithm steps: - - 1. mark all objects as white (remaining white objects will later be - considered orphan) - 2. scan the memory starting with the data section and stacks, checking - the values against the addresses stored in the prio search tree. If - a pointer to a white object is found, the object is added to the - gray list - 3. scan the gray objects for matching addresses (some white objects - can become gray and added at the end of the gray list) until the - gray set is finished - 4. the remaining white objects are considered orphan and reported via - /sys/kernel/debug/kmemleak - -Some allocated memory blocks have pointers stored in the kernel's -internal data structures and they cannot be detected as orphans.

To reduce the number of false negatives, kmemleak -provides the kmemleak_ignore, kmemleak_scan_area, kmemleak_no_scan and -kmemleak_erase functions (see above). The task stacks also increase the -amount of false negatives and their scanning is not enabled by default. - -The false positives are objects wrongly reported as being memory leaks -(orphan). For objects known not to be leaks, kmemleak provides the -kmemleak_not_leak function. The kmemleak_ignore could also be used if -the memory block is known not to contain other pointers and it will no -longer be scanned. - -Some of the reported leaks are only transient, especially on SMP -systems, because of pointers temporarily stored in CPU registers or -stacks. Kmemleak defines MSECS_MIN_AGE (defaulting to 1000) representing -the minimum age of an object to be reported as a memory leak. - -Limitations and Drawbacks -------------------------- - -The main drawback is the reduced performance of memory allocation and -freeing. To avoid other penalties, the memory scanning is only performed -when the /sys/kernel/debug/kmemleak file is read. Anyway, this tool is -intended for debugging purposes where the performance might not be the -most important requirement. - -To keep the algorithm simple, kmemleak scans for values pointing to any -address inside a block's address range. This may lead to an increased -number of false negatives. However, it is likely that a real memory leak -will eventually become visible. - -Another source of false negatives is the data stored in non-pointer -values. In a future version, kmemleak could only scan the pointer -members in the allocated structures. This feature would solve many of -the false negative cases described above. - -The tool can report false positives. These are cases where an allocated -block doesn't need to be freed (some cases in the init_call functions), -the pointer is calculated by other methods than the usual container_of -macro or the pointer is stored in a location not scanned by kmemleak. - -Page allocations and ioremap are not tracked.

+----------------------------------------------------------------- +$Id: README,v 1.1 2001/12/17 13:59:27 bjornw Exp $ + +This can be slightly confusing because it's a process with many steps. + +The kernel object built by the arch/etrax100/Makefile, vmlinux, is split +by that makefile into text and data binary files, vmlinux.text and +vmlinux.data. + +Those files together with a ROM filesystem can be catted together and +burned into a flash or executed directly at the DRAM origin. + +They can also be catted together and compressed with gzip, which is what +happens in this makefile. Together they make up piggy.img. + +The decompressor is built into the file decompress.o. It is turned into +the binary file decompress.bin, which is catted together with piggy.img +into the file vmlinuz. It can be executed in an arbitrary place in flash. + +Be careful - it assumes some things about free locations in DRAM. It +assumes the DRAM starts at 0x40000000 and that it is at least 8 MB, +so it puts its code at 0x40700000, and initial stack at 0x40800000. + +-Bjorn diff --git a/trunk/arch/cris/boot/compressed/decompress_v10.lds b/trunk/arch/cris/arch-v10/boot/compressed/decompress.lds similarity index 100% rename from trunk/arch/cris/boot/compressed/decompress_v10.lds rename to trunk/arch/cris/arch-v10/boot/compressed/decompress.lds diff --git a/trunk/arch/cris/boot/compressed/head_v10.S b/trunk/arch/cris/arch-v10/boot/compressed/head.S similarity index 97% rename from trunk/arch/cris/boot/compressed/head_v10.S rename to trunk/arch/cris/arch-v10/boot/compressed/head.S index 9edb8ade7e1f..0bb4dcc29254 100644 --- a/trunk/arch/cris/boot/compressed/head_v10.S +++ b/trunk/arch/cris/arch-v10/boot/compressed/head.S @@ -30,7 +30,7 @@ beq dram_init_finished nop -#include "../../arch-v10/lib/dram_init.S" +#include "../../lib/dram_init.S" dram_init_finished: @@ -123,4 +123,4 @@ _cmd_line_magic: .dword 0 _cmd_line_addr: .dword 0 -#include "../../arch-v10/lib/hw_settings.S" +#include "../../lib/hw_settings.S" diff --git a/trunk/arch/cris/arch-v10/boot/compressed/misc.c b/trunk/arch/cris/arch-v10/boot/compressed/misc.c new file mode 100644 index 000000000000..a4db1507d3b1 --- /dev/null +++ b/trunk/arch/cris/arch-v10/boot/compressed/misc.c @@ -0,0 +1,246 @@ +/* + * misc.c + * + * This is a collection of several routines from gzip-1.0.3 + * adapted for Linux. + * + * malloc by Hannu Savolainen 1993 and Matthias Urlichs 1994 + * puts by Nick Holloway 1993, better puts by Martin Mares 1995 + * adaptation for Linux/CRIS Axis Communications AB, 1999 + * + */ + +/* where the piggybacked kernel image expects itself to live. + * it is the same address we use when we network load an uncompressed + * image into DRAM, and it is the address the kernel is linked to live + * at by vmlinux.lds.S + */ + +#define KERNEL_LOAD_ADR 0x40004000 + + +#include +#include + +/* + * gzip declarations + */ + +#define OF(args) args +#define STATIC static + +void *memset(void *s, int c, size_t n);

If a pinned counter cannot be put onto the -CPU (e.g. because there are not enough hardware counters or because of -a conflict with some other event), then the counter goes into an -'error' state, where reads return end-of-file (i.e. read() returns 0) -until the counter is subsequently enabled or disabled. - -The 'exclusive' bit, if set, specifies that when this counter's group -is on the CPU, it should be the only group using the CPU's counters. -In future, this will allow sophisticated monitoring programs to supply -extra configuration information via 'extra_config_len' to exploit -advanced features of the CPU's Performance Monitor Unit (PMU) that are -not otherwise accessible and that might disrupt other hardware -counters. - -The 'exclude_user', 'exclude_kernel' and 'exclude_hv' bits provide a -way to request that counting of events be restricted to times when the -CPU is in user, kernel and/or hypervisor mode. - -The 'mmap' and 'munmap' bits allow recording of PROT_EXEC mmap/munmap -operations, these can be used to relate userspace IP addresses to actual -code, even after the mapping (or even the whole process) is gone, -these events are recorded in the ring-buffer (see below). - -The 'comm' bit allows tracking of process comm data on process creation. -This too is recorded in the ring-buffer (see below). - -The 'pid' parameter to the perf_counter_open() system call allows the -counter to be specific to a task: - - pid == 0: if the pid parameter is zero, the counter is attached to the - current task. - - pid > 0: the counter is attached to a specific task (if the current task - has sufficient privilege to do so) - - pid < 0: all tasks are counted (per cpu counters) - -The 'cpu' parameter allows a counter to be made specific to a CPU: - - cpu >= 0: the counter is restricted to a specific CPU - cpu == -1: the counter counts on all CPUs - -(Note: the combination of 'pid == -1' and 'cpu == -1' is not valid.) - -A 'pid > 0' and 'cpu == -1' counter is a per task counter that counts -events of that task and 'follows' that task to whatever CPU the task -gets schedule to. Per task counters can be created by any user, for -their own tasks. - -A 'pid == -1' and 'cpu == x' counter is a per CPU counter that counts -all events on CPU-x. Per CPU counters need CAP_SYS_ADMIN privilege. - -The 'flags' parameter is currently unused and must be zero. - -The 'group_fd' parameter allows counter "groups" to be set up. A -counter group has one counter which is the group "leader". The leader -is created first, with group_fd = -1 in the perf_counter_open call -that creates it. The rest of the group members are created -subsequently, with group_fd giving the fd of the group leader. -(A single counter on its own is created with group_fd = -1 and is -considered to be a group with only 1 member.) - -A counter group is scheduled onto the CPU as a unit, that is, it will -only be put onto the CPU if all of the counters in the group can be -put onto the CPU. This means that the values of the member counters -can be meaningfully compared, added, divided (to get ratios), etc., -with each other, since they have counted events for the same set of -executed instructions. - - -Like stated, asynchronous events, like counter overflow or PROT_EXEC mmap -tracking are logged into a ring-buffer.
