Oh, this may be some 32bit compatibility support issue. I could check the thread vmas when running 64bit binary directly on IPF platform. :) Thanks, Kevin -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Tian, Kevin Sent: 2003年11月20日 14:17 To: [email protected] Subject: How to check the vma maps of threads in /proc? Hi, all, I’d like to check the vma maps of created threads, but failed to do that. Currently all threads in a process group will only show as one entry in /proc with group id, right? When I pause the running threads and read the maps file under this entry, it seemed that only process information is recorded, such as: --------------------------------------------- 0000000008048000-000000000804c000 rwxp 0000000000000000 00:00 0 000000000804c000-000000000806c000 rwxp 0000000000000000 00:00 0 0000000040000000-0000000040014000 r-xp 0000000000000000 08:07 571222 /emul/ia32-linux/lib/ld-2.3.2.so 0000000040014000-0000000040018000 rwxp 0000000000000000 00:00 0 0000000040028000-000000004002c000 r-xp 0000000000010000 08:07 244950 /etc/ld.so.cache 000000004002c000-0000000040038000 r-xp 0000000000000000 08:07 440673 /emul/ia32-linux/lib/tls/libpthread-0.60.so 0000000040038000-0000000040040000 rwxp 0000000000000000 00:00 0 0000000040040000-0000000040170000 r-xp 0000000000000000 08:07 440669 /emul/ia32-linux/lib/tls/libc-2.3.2.so 0000000040170000-00000000479a8000 rwxp 0000000000000000 00:00 0 00000000bfffc000-00000000c0000000 rwxp 0000000000000000 00:00 0 00000000c0000000-00000000c0004000 r--p 0000000000000000 00:00 0 00000000c0008000-00000000c0018000 rw-p 0000000000000000 00:00 0 --------------------------------------------- I just want to know if I missed something when kernel configuration, or need other effort to achieve the goal. Or is it complete impossible to check thread vmas in current kernel…… I just guess. :) P.S. The environment is based on running 32bit binary on IPF platform. Thanks, Kevin
