SAN19-204 Road to SVE enablement in LLDB
Arm’s Scalable Vector Extension (SVE) has introduced a new challenge to the debugger world where vector register size is unknown until run time and also can change during execution. Arm has been innovating in the past year or so to live up to the challenge of SVE in GDB. Linaro has begun to do the same for the LLDB debugger in the LLVM toolchain world. In this talk we will briefly introduce SVE and its impact on debugger’s register access design. Moreover, we will discuss SVE support in LLDB, will give an overview of the whole effort and will provide updates about completed, in progress and completed tasks.

SAN19-206 SVE/SVE2 support in LLVM and GNU toolchains
Arm announced SVE2, in early 2019, which allows a wider range of software to benefit from the advanced, scalable SIMD vector technology of the original SVE architecture (announced in 2017). In this talk, the presenter will provide an update on the status and roadmap of SVE and SVE2 support in LLVM and GNU toolchains.

SAN19-223 Using Perf and its friend eBPF on Arm platform
Perf has joined a growing number of tools able to act as userspace interface to eBPF. Not only that but it can also reprise its historic role as the best interface to the Linux performance monitoring sub-system to profile eBPF programs installed by itself or any other eBPF front end.

This session will mainly give updates for latest support for Arm CoreSight and eBPF in perf, and also will see how to Arm CoreSight can be used for eBPF program profiling.

This session will be divided into two main parts; the first part will focus on the updates for Arm CoreSight tracing, includes sample flags and integration perf for test support. In the bottom part, it will discuss the eBPF usage with perf tool: perf uses eBPF program for system call tracing; perf profiles the eBPF program by using the general PMU events and Arm CoreSight event.

This session will be finished within 25 minutes; in the CoreSight hacking session we will concentrate on questions
and demonstrations as the supplement to the presentation.
