Yes indeed. I added the pid to the front for the case where you are using --cgroup without --summary; in that case, each vma will be printed for each pid in the cgroup and it seemed sensible to be able to see which pid each vma belonged to. > > Perhaps the pid should be printed in decimal? I thought about printing in decimal, but every other value in the vma is in hex without a leading "0x" (I'm trying to follow the smaps convention). So I thought it could be more confusing in decimal. I'm happy to change it to decimal if that's the preference though? Although I'd like to continue to present it in a fixed width field, padded with 0s on the left so that everything lines up. > > -- William Kucharski > >> /thpmaps --pid 206 --cont 64K >> 000000ce 0000aaaadbb20000-0000aaaadbb21000 r-xp 00000000 fe:00 >> 00426969 /root/a.out >> 000000ce 0000aaaadbb3f000-0000aaaadbb40000 r--p 0000f000 fe:00 >> 00426969 /root/a.out >> 000000ce 0000aaaadbb40000-0000aaaadbb41000 rw-p 00010000 fe:00 >> 00426969 /root/a.out >> 000000ce 0000ffff702c0000-0000ffffb02c0000 rw-p 00000000 00:00 00000000 >> anon-thp-aligned-64kB: 473920 kB (100%) >> anon-cont-aligned-64kB: 473920 kB (100%) >> 000000ce 0000ffffb02c0000-0000ffffb044c000 r-xp 00000000 fe:00 >> 00395429 /usr/lib/aarch64-linux-gnu/libc.so.6 >> 000000ce 0000ffffb044c000-0000ffffb045d000 ---p 0018c000 fe:00 >> 00395429 /usr/lib/aarch64-linux-gnu/libc.so.6 >> 000000ce 0000ffffb045d000-0000ffffb0460000 r--p 0018d000 fe:00 >> 00395429 /usr/lib/aarch64-linux-gnu/libc.so.6 >> 000000ce 0000ffffb0460000-0000ffffb0462000 rw-p 00190000 fe:00 >> 00395429 /usr/lib/aarch64-linux-gnu/libc.so.6 >> 000000ce 0000ffffb0462000-0000ffffb046f000 rw-p 00000000 00:00 00000000 >> 000000ce 0000ffffb0477000-0000ffffb049d000 r-xp 00000000 fe:00 >> 00393893 /usr/lib/aarch64-linux-gnu/ld-linux-aarch64.so.1 >> 000000ce 0000ffffb04b0000-0000ffffb04b2000 rw-p 00000000 00:00 00000000 >> 000000ce 0000ffffb04b2000-0000ffffb04b4000 r--p 00000000 00:00 00000000 [vvar] >> 000000ce 0000ffffb04b4000-0000ffffb04b5000 r-xp 00000000 00:00 00000000 [vdso] >> 000000ce 0000ffffb04b5000-0000ffffb04b7000 r--p 0002e000 fe:00 >> 00393893 /usr/lib/aarch64-linux-gnu/ld-linux-aarch64.so.1 >> 000000ce 0000ffffb04b7000-0000ffffb04b9000 rw-p 00030000 fe:00 >> 00393893 /usr/lib/aarch64-linux-gnu/ld-linux-aarch64.so.1 >> 000000ce 0000ffffdaba4000-0000ffffdabc5000 rw-p 00000000 00:00 00000000 [stack] >
