[Crash-utility] Difference in vtop with and without PAE ?

Hello, 1) I think, there is a difference in vtop when PAE is not configured and is configured (kernel 2.6.11) Any reason ? I use a very simple program #include <stdio.h> #include <stdlib.h> int var12=12; main() { printf("@var12 : %p\n", &var12); pause(); } ***************PAE not configured************** [root@fedora4 ~]# ./essai & [1] 3196 [root@fedora4 ~]# @var12 : 0x80495a8 [root@fedora4 ~]# crash -s crash> set 3196 [.] crash> vtop 0x80495a8 VIRTUAL PHYSICAL 80495a8 1e28c5a8 PAGE DIRECTORY: dda2f000 PGD: dda2f080 => 1f0a7067 PMD: dda2f080 => 1f0a7067 PTE: 1f0a7124 => 1e28c067 PAGE: 1e28c000 <---------------------------- [...] PAGE is the physical address of the page ***************PAE configured ****************** [root@fedora4 ~]# ./essai & [2] 7268 [root@fedora4 ~]# @var12 : 0x80495a8 [root@fedora4 ~]# crash -s crash> set 7268 [.] crash> vtop 0x80495a8 VIRTUAL PHYSICAL 80495a8 6d925a8 PAGE DIRECTORY: dfe08560 PGD: dfe08560 => 1b223001 PMD: 1b223200 => 187bf067 PTE: 187bf248 => 6d92067 PAGE: 6d925a8 <---------------------------------- [...] PAGE is really the physical adress of var12 2) Also an option should be nice in rd to see hexadecimal without the ascii part With PAE on, if i want du see the 4 references in the PGD, i am not really interested in the ascii part ? crash> rd -64 df7e2b60 4 df7e2b60: 000000001b086001 000000001c932001 .`....... ...... df7e2b70: 000000001f991001 0000000000004001 .........@...... crash> rd -32 df7e2b60 8 df7e2b60: 1b086001 00000000 1c932001 00000000 .`....... ...... df7e2b70: 1f991001 00000000 00004001 00000000 .........@......
