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

tpm: tpm_spapr: Remove unused tracepoint

2021-01-26T01:56:38+00:00

Linking of qemu-system-ppc64 fails on macOS with dtrace enabled: error: probe tpm_spapr_show_buffer doesn't exist error: Could not register probes ld: error creating dtrace DOF section for architecture x86_64 The failure is explained in 8c8ed03850208e4 ("net/colo: Match is-enabled probe to tracepoint"). In short, is-enabled probe can't be used without a matching trace probe. And for this particular case tpm_util_show_buffer probe should be enabled to print TPM buffer.

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.

tpm: Move backend code under the 'backends/' directory

2020-06-19T11:25:55+00:00

TPM subsytem is split into backends (see commit f4ede81eed2) and frontends (see i.e. 3676bc69b35). Keep the emulated hardware 'frontends' under hw/tpm/, but move the backends in the backends/tpm/ directory.

tpm_spapr: Support TPM for ppc64 using CRQ based interface

2020-02-02T03:07:57+00:00

Implement support for TPM on ppc64 by implementing the vTPM CRQ interface as a frontend. It can use the tpm_emulator driver backend with the external swtpm. The Linux vTPM driver for ppc64 works with this emulation. This TPM emulator also handles the TPM 2 case.

trace: Eliminate use of TARGET_FMT_plx

2019-08-16T11:31:51+00:00

hw/tpm/trace-events uses TARGET_FMT_plx formats with uint64_t arguments. That's wrong, TARGET_FMT_plx takes hwaddr. Since hwaddr happens to be uint64_t, it works anyway. Messed up in commit ec427498da5, v2.12.0. Clean up by replacing TARGET_FMT_plx with its macro expansion. scripts/tracetool/format/log_stap.py (commit 62dd1048c0b, v4.0.0) has a special case for TARGET_FMT_plx. Delete it.

trace-events: Shorten file names in comments

2019-03-22T16:18:07+00:00

We spell out sub/dir/ in sub/dir/trace-events' comments pointing to source files. That's because when trace-events got split up, the comments were moved verbatim. Delete the sub/dir/ part from these comments. Gets rid of several misspellings.

tpm_tis: convert tpm_tis_show_buffer() to use trace event

2019-02-24T19:46:14+00:00

cppcheck reports: [hw/tpm/tpm_tis.c:113]: (warning) %d in format string (no. 2) requires 'int' but the argument type is 'unsigned int' Rather than just converting the format specifier to use '%u", the tpm_tis_show_buffer() function is converted to use trace points and the two debug callers use the trace event infrastructure so that it's available in production cases also and not just when DEBUG_TIS is enabled.
