Commit e50caf4a5c ("tracing: convert documentation to rST") converted docs/devel/tracing.txt to docs/devel/tracing.rst. We still have several references to the old file, so let's fix them with the following command: sed -i s/tracing.txt/tracing.rst/ $(git grep -l docs/devel/tracing.txt) Signed-off-by: Stefano Garzarella Reviewed-by: Philippe Mathieu-Daudé Message-Id: <20210517151702.109066-2-sgarzare@redhat.com> Signed-off-by: Thomas Huth

util/vfio-helpers: Convert vfio_dump_mapping to trace events

2020-11-03T19:06:23+00:00

The QEMU_VFIO_DEBUG definition is only modifiable at build-time. Trace events can be enabled at run-time. As we prefer the latter, convert qemu_vfio_dump_mappings() to use trace events instead of fprintf().

util/vfio-helpers: Trace PCI I/O config accesses

2020-11-03T19:06:22+00:00

We sometime get kernel panic with some devices on Aarch64 hosts. Alex Williamson suggests it might be broken PCIe root complex. Add trace event to record the latest I/O access before crashing. In case, assert our accesses are aligned.

trace-events: Fix attribution of trace points to source

2020-09-09T16:17:58+00:00

Some trace points are attributed to the wrong source file. Happens when we neglect to update trace-events for code motion, or add events in the wrong place, or misspell the file name. Clean up with help of scripts/cleanup-trace-events.pl. Funnies requiring manual post-processing: * accel/tcg/cputlb.c trace points are in trace-events. * block.c and blockdev.c trace points are in block/trace-events. * hw/block/nvme.c uses the preprocessor to hide its trace point use from cleanup-trace-events.pl. * hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to guard debug code. * include/hw/xen/xen_common.h trace points are in hw/xen/trace-events. * linux-user/trace-events abbreviates a tedious list of filenames to */signal.c. * net/colo-compare and net/filter-rewriter.c use pseudo trace points colo_compare_miscompare and colo_filter_rewriter_debug to guard debug code.
