This is a feature to track the new features on GDB on Ubuntu 14.10.

The request is to add TAR register support,  PPR, DSCR as miscellaneous
registers. This request also covers a set of TM related ptrace requests
covering related SPR and various check-pointed registers.

Leader: Edjunior Barbosa

Bugs:

https://bugs.launchpad.net/tasty-taco/+bug/1278706 ( gdb not able to
display TAR register )

It depends on kernel enablement, updating Power ptrace interface to have access to the new registers (bug #104280)

Ed,

It seems that the patch was finally accepted in

https://git.kernel.org/cgit/linux/kernel/git/next/linux-
next.git/commit/?id=96d016108640bc2b7fb0ee800737f80923847294

Is it correct?

This is actually a fix for a issue related to DSCR value that were being
discussed when the ptrace patch was submitted (as mentioned in
https://bugzilla.linux.ibm.com/show_bug.cgi?id=104280#c5). The patchset
updating the ptrace interface to include the new registers is still
waiting for review in the kernel mailing list.

Right, what is the status on the GDB part? Is it already done, or, does it depend on those patches accepted before starting the development?

GDB part is depending on the kernel side patches to start the
development.

This is going to be deferred to Ubuntu 15.04. 

Si Yuan, let me know if it doesn't work for you.
