adding branch tracing and reverse debugging in GDB using Coresight etm traces

[zied guermazi]

hiI am progressing in the implementation of the proposal "GDB process record 
and replay with ARM Coresight"  
https://lists.linaro.org/pipermail/coresight/2019-July/003021.html
so far I was able to use perf events to configure the drivers for etm and 
collect the traces. the code was tested successfully on an STM32MP157A 
discovery kit (arm v7). and I can collect the traces from the perf mmapped aux 
area. 
For parsing them I needed to gather information about the cpu and etm  
registers. those are available in the events of type PERF_RECORD_AUXTRACE_INFO 
in the priv section. priv is a kind of "opaque" data structure where the layout 
is depending on the perf pmu drivers. the implementation of perf tool gives a 
good example to follow. I needed also to make a wrapper around opencsd library 
and again perf was offering a good example to follow. 
those are good reasons to think about factoring out the functionality of 
parsing etm traces on linux system in a dedicated library that can be reused by 
other software, a kind of libcoresightperf.is there any plan or ongoing 
activities for such a library?
Kind RegardsZied Guermazi

[ACTIVITY] report week ending 24 Jan

[Peter Maydell]

Progress:
 * VIRT-65 [QEMU upstream maintainership]
  - code review:
   + RTH's bug fix for the PAuth ComputePAC operation
   + patchset adding DMA support for Exynos4210 UARTs
  - small patchset documenting the right way to conditionally run
expensive computations that are only needed for trace event output,
and updating a handful of places that used an older (worse) method
  - more QEMU documentation conversion to rST; in particular wrote a
Sphinx 'hxtool' extension to handle pulling out fragments of documentation
from QEMU's '.hx' files which define and document command line options

thanks
