* Off on Wed afternoon [1/10]. # Progress # * Fails in gdb.threads/multiple-step-overs.exp, (TCWG-332) [1/10] Patch V2 is posted, pending for review. * TCWG-422, patch is committed. Done. [2/10]. * TCWG-423, patches are ready, being regression tested. [2/10] * TCWG-433, build GDB with

[ACTIVITY] 26-30 October 2015

# Progress # * TCWG-332, [1/10], patch is posted for review. * TCWG-187, [1/10], looks like a kernel (~3.4) bug on setting VFP registers through ptrace. Fails go away after I upgrade the kernel. * TCWG-387, [2/10], binutils patch is committed, while GDB patches are being reviewed. *

[ACTIVITY] 19 - 23 October 2015

* Two days (Tue and Thu) off. [4/10] # Progress # * TCWG-180, patch is committed by Andrew Stubs. [1/10] I review and approve it. * Review patch set "all-stop on top of non-stop for remote". [3/10] Test them on aarch64 and arm. Triage and fix one regression. Review is still on going.

[ACTIVITY] 12th - 16th October

# Progress # * TCWG-162, Aarch64 non-stop debugging (or displaced stepping). [1/10] Patches are committed. * TCWG-335, HW breakpoint on 2-byte aligned address, [3/10] patch is tested against most recent kernel. Everything works. Patch is committed. * TCWG-166, Review ARM software

[ACTIVITY] 5th October -- 9th October

# Progress # * TCWG-162, Aarch64 non-stop debugging (or displaced stepping). [4/10] After testing, patches are posted upstream. * In order to review one c++ debugging patch, learn some C++ abi, vtable and VTT, etc. Understand gcc dump by -fdump-class-hierarchy. [3/10] * Fix GDB cxx build

[ACTIVITY] 28 September-2 October 2015

# Progress # * TCWG-373, Aarch64 non-stop debugging (or displaced stepping). [2/10] Patches V1 are ready for upstream submission, but find opcodes has already interfaces to decode instructions, so decide to use opcodes for aarch64 GDB first. * TCWG-387, one patch exposing one opcode

[ACTIVITY] 21th-25th September

# Progress # * TCWG-189, Aarch64 fast tracepoint. [2/10] Done. Patches are committed. * TCWG-373, Support displaced stepping on aarch64-linux. [4/10] GDB works basically, still need to refactor and polish the code. * TCWG-374, Test displaced stepping on aarch64-linux. [1/10] Add new

[ACTIVITY] 14th-18th September

# Progress # * TCWG-188, aarch64 GDB multi-arch support. [2/10] All patches went upstream except that one is blocked by kernel patch. The work is done! * TCWG-189, aarch64 fast tracepoint support. [2/10] Update them and post V2 out. Pending for review. * TCWG-373, Aarch64 non-stop

[ACTIVITY] 07 Sep -- 11 Sep

# Progress # * TCWG-857, [7/10] One patch is upstreamed. The rest of them are in the queue. Upgrade juno board linux kernel to 4.2.0-rc4+ to test some multi-arch kernel patches. It isn't easy to run that new kernel on juno board, takes much time on this. * Misc [3/10]. Meetings, online

[ACTIVITY] 31th Aug - 04th Sep

# 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

[ACTIVITY] 24th - 28th August

# Progress # * TCWG-857 [3/10] With one kernel fix, HW breakpoint works for unaligned address (2-byte aligned). Debug linux kernel with KGDB. KGDB exposes an existing GDB bug, I fixed it, but need some time thinking about how to submit it upstream. * TCWG-567, arm watchpoint fixes

[ACTIVITY] 17 - 21 August 2015

# Progress # * TCWG-806, aarch64 remote debugging multi-arch support. Patches are pushed in. Done. [2/10] * TCWG-857, HW breakpoint/watchpoint in multi-arch. [3/10] Both GDB and linux kernel needs some fixes. Fix one bug in GDB. Read ARMv8 manual about byte address select for thumb

[ACTIVITY] 27th - 31th July

# Progress # * TCWG-806, aarch64 remote debugging multi-arch support. [4/10] Patches are posted upstream. * TCWG-860, aarch64 fast tracepoint. [1/10] Patch review and some discussions. * TCWG-757, upstream patch review. [2/10]. ** Review NIOS II R2 patches. ** Fix PR record/18691. *
