So basically keep track of the objects separately. Got that working
for the modular builds. Progress!!!
Non-modular builds fail due to missing qxl tracepoints. Tried to fix
that with a simple 'softmmu_ss.add(module_trace_src)'. Now I get:
../../meson.build:1802:2: ERROR: Object extraction arguments must be strings or
Files.
/me looks surprised. Doing trace_ss.add(module_trace_src) in
trace/meson.buikd works just fine ...
Branch available at git://git.kraxel.org/qemu sirius/trace-modules
Running "qemu -device qxl" segfaults. Not investigated yet, but I guess
this is just modular tracepoint not being properly initialized. Will
check later, have to run pick up my daughter now.
take care,
Gerd
