gdbstub: move into its own sub directory

2022-10-06T10:53:41+00:00

This is in preparation of future refactoring as well as cleaning up the source tree. Aside from the minor tweaks to meson and trace.h this is pure code motion. Reviewed-by: Richard Henderson Signed-off-by: Alex Bennée Message-Id: <20220929114231.583801-43-alex.bennee@linaro.org>

tracing: remove TCG memory access tracing

2022-02-09T12:08:42+00:00

If you really want to trace all memory operations TCG plugins gives you a more flexible interface for doing so.

trace: Split guest_mem_before

2021-10-05T23:53:17+00:00

There is no point in encoding load/store within a bit of the memory trace info operand. Represent atomic operations as a single read-modify-write tracepoint. Use MemOpIdx instead of inventing a form specifically for traces. Reviewed-by: Philippe Mathieu-Daudé Signed-off-by: Richard Henderson

docs: fix references to docs/devel/tracing.rst

2021-06-02T04:51:09+00:00

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

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.

softmmu: Add missing trace-events file

2020-09-09T16:15:18+00:00

Commit c7f419f584 moved softmmu-only files out of the root directory, but forgot to move the trace events, which should no longer be generated to "trace-root.h". Fix that by adding softmmu/trace-events.

trace: add mmu_index to mem_info

2019-10-28T15:12:38+00:00

We are going to re-use mem_info later for plugins and will need to track the mmu_idx for softmmu code. Signed-off-by: Alex Bennée

trace: expand mem_info:size_shift to 4 bits

2019-10-28T15:12:38+00:00

This will allow us to trace 32k-long memory accesses (although our maximum is something like 256 bytes at the moment). Reviewed-by: Alex Bennée Signed-off-by: Emilio G. Cota [AJB: expanded to 3->4 bits] Signed-off-by: Alex Bennée Reviewed-by: Richard Henderson

exec: Adjust notdirty tracing

2019-09-25T17:38:07+00:00

The memory_region_tb_read tracepoint is unreachable, since notdirty is supposed to apply only to writes. The memory_region_tb_write tracepoint is mis-named, because notdirty is not only used for TB invalidation. It is also used for e.g. VGA RAM updates and migration. Replace memory_region_tb_write with memory_notdirty_write_access, and place it in memory_notdirty_write_prepare where it can catch all of the instances. Add memory_notdirty_set_dirty to log when we no longer intercept writes to a page.
