if (fd < 0) {
printf("[ERROR] open device err\n");
return -1;
}
addr = mmap(0, len, prot, MAP_SHARED, fd, offset);

--run with valgrind :
valgrind --leak-check=full --show-leak-kinds=all -v --log-file=valgrind.log ./build/valgrind-test --base-virtaddr=0x4000000000
-- The valgrind log reported the following error with mmap：
valgrind: m_debuginfo/image.c:587 (set_CEnt): Assertion '! sr_isError(sr)' failed.
--strace valgrind:
open("/sys/class/mdev_bus/0000:06:00.0/resource4", O_RDWR|O_SYNC) = 94 rt_sigprocmask(SIG_SETMASK, ~[ILL TRAP BUS FPE KILL SEGV STOP SYS], NULL, 8) = 0
gettid() = 13758
read(1028, "Y", 1) = 1
mmap(0x4033000, 4096, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_FIXED, 94, 0x320000) = 0x4033000
syscall_332(0x5e, 0x58246543, 0x1000, 0xfff, 0x1003633aa0, 0) = 0
readlink("/proc/self/fd/94", "/sys/devices/pci0000:00/0000:00:"..., 4096) = 59
syscall_332(0xffffffffffffff9c, 0x597789da, 0, 0xfff, 0x10036346d0, 0) = 0
syscall_332(0x5e, 0x58246543, 0x1000, 0xfff, 0x1003634560, 0) = 0
pread64(94, 0x100299acd0, 8192, 0) = -1 EIO (Input/output error)
valgrind will do pread64 after mmap ??
4 run directly:
-- There is no problem with mmap
-- use pread64(..) will cause io error
5 Quesions:
How can I use valgrind in this case

It contains workarounds to several common problems. In particular, if Valgrind aborted or crashed after identifying problems in your program, there's a good chance that fixing those problems will prevent Valgrind aborting or crashing, especially if it happened in m_mallocfree.c. If that doesn't help, please report this bug to: www.valgrind.org In the bug report, send all the above text, the valgrind version, and what OS and version you are using. Thanks.
