i changed long offset to unsigned ,mmap succeed.
do_sys_mmap()
does not exist in this ~dojo~ repo, does it? It does exist in https://github.com/gperftools/gperftools, which is where you will need to (re)file your issue.
ok,thanks
used tcmalloc lib with hisi32bit platform, i need mmap an address and offset param is physical address(0x9240a000), but mmap failed.
static void* do_sys_mmap(long sysnr, void* start, size_t length, int prot, int flags, int fd, long offset)
, i think offset param type should be unsigned long .signed type will lost Precision .
