util/elogtool: add tool to print elog events Add a new tool that that prints elog events. The tool, as input, accepts either a file with the RW_ELOG contents, or if the file is not provided it reads the contents of RW_ELOG by calling the "flashrom" tool. The tool is based on "mosys eventlog list"[1]. For the moment it only supports "list", but future commits will add additional functionality. This commit also adds missing ELOG defines needed for the tool. These defines are added with the rest of the ELOG defines, in include/commonlib/bsd/elog.h The tool is placed inside util/cbfstool. The rationale behind the decision, is that this tool shares a lot in common with the other tools located in cbfstool: vboot dependency, shared files like common.o and valstr.o, and in spirit is similar to some of the tools located in cbfstool/. As an example, you call the tool like the following: $ elogtool list -f rw_elog_dump.bin [1]: https://chromium.googlesource.com/chromiumos/platform/mosys/+/refs/heads/main/lib/eventlog/elog.c BUG=b:172210863 Signed-off-by: Ricardo Quesada <ricardoq@google.com> Change-Id: Ia1fe1c9ed3c4c6bda846055d4b10943b54463935 Reviewed-on: https://review.coreboot.org/c/coreboot/+/56406 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-by: Jack Rosenthal <jrosenth@chromium.org>

elogtool: add "clear" command Adds "clear" command to cbfsutil/elogtool tool. "clear" clears the RW_ELOG region by using either: * flashrom if no file is provided * or using file write if an input file is provided. The region is filled with ELOG_TYPE_EOL. And a ELOG_TYPE_LOG_CLEAR event is inserted. Additionally, it does a minor cleanup to command "list", like: * use buffer_end() * add "list" to the cmds struct * and make elog_read() very similar to elog_write() Usage: $ elogtool clear BUG=b:172210863 TEST=elogtool clear && elogtool list elogtool clear -f invalid.raw elogtool clear -f valid.raw Change-Id: Ia28a6eb34c82103ab078a0841b022e2e5e430585 Signed-off-by: Ricardo Quesada <ricardoq@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/56883 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com> Reviewed-by: Jack Rosenthal <jrosenth@chromium.org>

util/cbfstool/eventlog: Use LocalTime or UTC timestamps Add a new flag "--utc" to allow the user to choose if elogtool should print timestamps in Local Time or in UTC. It is useful for generating automated crash reports including all system logs when users are located in various regions (timezones).

util/elogtool: add tool to print elog events Add a new tool that that prints elog events. The tool, as input, accepts either a file with the RW_ELOG contents, or if the file is not provided it reads the contents of RW_ELOG by calling the "flashrom" tool. The tool is based on "mosys eventlog list"[1]. For the moment it only supports "list", but future commits will add additional functionality. This commit also adds missing ELOG defines needed for the tool. These defines are added with the rest of the ELOG defines, in include/commonlib/bsd/elog.h The tool is placed inside util/cbfstool. The rationale behind the decision, is that this tool shares a lot in common with the other tools located in cbfstool: vboot dependency, shared files like common.o and valstr.o, and in spirit is similar to some of the tools located in cbfstool/. As an example, you call the tool like the following: $ elogtool list -f rw_elog_dump.bin [1]: https://chromium.googlesource.com/chromiumos/platform/mosys/+/refs/heads/main/lib/eventlog/elog.c BUG=b:172210863 Signed-off-by: Ricardo Quesada <ricardoq@google.com> Change-Id: Ia1fe1c9ed3c4c6bda846055d4b10943b54463935 Reviewed-on: https://review.coreboot.org/c/coreboot/+/56406 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-by: Jack Rosenthal <jrosenth@chromium.org>

util/elogtool: add tool to print elog events Add a new tool that that prints elog events. The tool, as input, accepts either a file with the RW_ELOG contents, or if the file is not provided it reads the contents of RW_ELOG by calling the "flashrom" tool. The tool is based on "mosys eventlog list"[1]. For the moment it only supports "list", but future commits will add additional functionality. This commit also adds missing ELOG defines needed for the tool. These defines are added with the rest of the ELOG defines, in include/commonlib/bsd/elog.h The tool is placed inside util/cbfstool. The rationale behind the decision, is that this tool shares a lot in common with the other tools located in cbfstool: vboot dependency, shared files like common.o and valstr.o, and in spirit is similar to some of the tools located in cbfstool/.

util/elogtool: add tool to print elog events Add a new tool that that prints elog events. The tool, as input, accepts either a file with the RW_ELOG contents, or if the file is not provided it reads the contents of RW_ELOG by calling the "flashrom" tool. The tool is based on "mosys eventlog list"[1]. For the moment it only supports "list", but future commits will add additional functionality. This commit also adds missing ELOG defines needed for the tool. These defines are added with the rest of the ELOG defines, in include/commonlib/bsd/elog.h The tool is placed inside util/cbfstool. The rationale behind the decision, is that this tool shares a lot in common with the other tools located in cbfstool: vboot dependency, shared files like common.o and valstr.o, and in spirit is similar to some of the tools located in cbfstool/.
