Title: Hardware watchpoints not working on ppc64le guests running on Ubuntu 14.10 host Status in gdb package in Ubuntu: New Bug description: == Comment: #0 - Edjunior Barbosa Machado <[email protected]> - 2015-01-26 06:38:42 == GDB hw watchpoints don't work on ppc64le VMs running on top of Ubuntu 14.10 Power8 host (sid.ltc.br.ibm.com). It fails quietly, ptrace calls and dmesg output display no error message. Tested on guests running different distros, kernel and gdb versions (distro's packages and upstream). Unfortunately, I couldn't find any other Ubuntu 14.10 host to double check the problem, but it worked OK in other hosts I've tried. Steps to reproduce: $ cat test.c int a; main(void) { a++; } $ gcc -g test.c -o test $ gdb ./test GNU gdb (Ubuntu 7.8.1-1ubuntu2) 7.8.1 ... Reading symbols from ./test...done. (gdb) watch a Hardware watchpoint 1: a (gdb) run Starting program: /home/emachado/test [Inferior 1 (process 8179) exited with code 0134] (gdb) Curiously, in the host it works as expected: $ gdb ./test GNU gdb (Ubuntu 7.8-1ubuntu4) 7.8.0.20141001-cvs ... Reading symbols from ./test...done. (gdb) watch a Hardware watchpoint 1: a (gdb) r Starting program: /home/emachado/test Hardware watchpoint 1: a Old value = 0 New value = 1 main () at test.c:5 5 } (gdb) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdb/+bug/1415917/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
