Hi all, I have executed the latest LTP test suite (ltp-full-20070930) on ARM OSK target having 32MB memory and noticed following test cases failed.
1. page01 1 FAIL : Test failed
In this test case memory size is assigned
memory_size = 256 * 1024 (256 KB)
and it allocates memory for each fork process
malloc(memory_size*sizeof(int));
It exceeds 32 MB and the test FAIL. For such low memory targets
memory_size should be less than 256 KB. Below change will fix this
issue for low memory targets.
ltp-full-20070930/testcases/kernel/mem/page/page01.c
- memory_size = 256 * 1024;
+ memory_size = 32 * 1024;
--------------------------------------------------------------------
2. shmt09 3 FAIL : Error: shmat Failed, shmid = 134938625, errno
= 22
shmat() system call is supposed to attach the memory segment at the
address
rounded to NEAREST multiple of SHMLBA which is PAGE_SIZE of the
system.
Here the testcase is checking the term NEAREST. In targets having low
memory
the system call is attaching the memory segment at the address which
is a
multiple of PAGE_SIZE but it is not nearest.
Below changes will fix this issue for low memory targets.
ltp-full-20070930/testcases/kernel/mem/shmt/shmt09.c
+#elif defined __arm__
+#define INCREMENT 32768 /* 32kb */
}
+#elif defined __arm__
+ vp = (void *)((char *)sbrk(0) + 32 * K_1);
-#if defined (__ia64__) || defined(__mips__) || defined(__hppa__)
+#if defined (__ia64__) || defined(__mips__) || defined(__hppa__) ||
defined(__arm__)
------------------------------------------------------------------------
3. shmat01 2 FAIL : shared memory address is not correct
This is same as above test and the patch to fix this issue for low
memory
targets is given below.
ltp-full-20070930/testcases/kernel/syscalls/ipc/shmat/shmat01.c
#elif defined __arm__
-#define UNALIGNED 0x28ffeeee
+#define UNALIGNED 0x5ff00eee
------------------------------------------------------------------------
The above changes works well for my 32MB ARM OSK target and the attached
file includes the patch for above fixes.
Please let me know your opinion about this.
