# Progress #

* Holiday on Monday [2/10]

* TCWG-857, [4/10]. All the multi-arch work are done
(I hope) but patches can't be sent out until kernel patches
are pushed in upstream.
** Collect some arguments from kernel folks to defend my change
"32-bit CPSR to 64-bit PSTATE". Patch is posted out.
** Finish the patch to convert siginfo_t between 32-bit debuggee
and 64-bit debugger. Done. Will post it next week.
** Get right TLS base in multi-arch debugging. Patch is done.

* Happen to see we can improve GDB performance in some case by
avoid sending some packets. Patch is done, but need to collect
some performance data. [2/10]

* Misc [1/10]
** Close some tickets, TCWG-567, TCWG-876, as they are done.

* TCWG-757 [1/10], many patches review.

# Plan #

* Continue to upstream multi-arch patches.
* Upgrade my juno board kernel to git master to test kernel patches
for multi-arch debugging work properly.
* Collect some GDB performance data for my patch.
