LAVA uinstance for benchmarking - TCWG-396 [3/10] * Long meeting with Renato + LAVA/lab people * Much thinking about the security side * Wrote up rough draft of what I understand the design to be Investigate effectiveness of noise control measures - TCWG-358 [3/10] * Set up new host node * Dealt with one host node crash, one target crash ** Noticed that target was writing logs to tmpfs, changed that so I can investigate next crash * Both sides stayed up through the weekend, hurrah * Some work on data-massaging scripts Misc [4/10] Heavier than usual week mail-wise, plus performance review prep =Plan= Clean up uinstance design, circulate to make sure we're all on same page Look at data from experiments so far Investigate B&B's Debian-building tools

# 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 breakage caused by my patch. [1/10] * Ask the effect of -fstack-check=specific to AArch64 prologue. GDB needs update. [1/10] * Misc, email, meeting. [1/10]. # Plan # * TCWG-162, commit patches if no objections. * TCWG-387, use libopcodes to decode instructions in GDB. -- Yao
