[RFC PATCH 0/5] Split Coresight decode by aux records

by James Clark

The following patches fix opening perf.data files that have timestamps (ordered data), aren't recorded with --per-thread, and that have discontinuous data in a single aux trace buffer. I have some open questions: * Can cs_etm__update_queues() be removed from cs_etm__flush_events()? * Why does the second commit start making some files process correctly? * Is it ok to wait for the flush to start processing? Previously processing happened when the first aux record was delivered to cs_etm__process_event(). * Do the aux records need to be saved into a new buffer or can they be pulled from elsewhere? I also have some further changes to make to make per-thread mode work where the cpu field of the sample is set to -1. And when there are no timestamps cs_etm__process_timeless_queues() is used, which is a completely different code path. Thanks James James Clark (5): perf cs-etm: Split up etm queue setup function perf cs-etm: Only search timestamp in current sample's queue. perf cs-etm: Save aux records in each etm queue perf cs-etm: don't process queues until cs_etm__flush_events perf cs-etm: split decode by aux records. tools/perf/util/cs-etm.c | 200 +++++++++++++++++++++++---------------- 1 file changed, 121 insertions(+), 79 deletions(-) -- 2.28.0

[PATCH v2 0/7] coresight: etm-perf: Fix pid tracing with VHE

by Leo Yan

This patch series is to support PID tracing with Virtualization Host Extensions (VHE). Since the patch series v1 was sent out for reviewing, we had some discussion and finalized the solution which is implemented in this version. Simply to say, to be backward compatibility, and can both support PID tracing for the kernel is running at either EL1 or EL2, the two new PMU formats "contextid1" and "contextid2" are introduced, which works as a switch to trace PID for EL1 kernel and EL2 kernel respectively. The existed PMU format "contextid" needs to be backward compatible for users, it's changed to an alias for "contextid1" on EL1 kernel and for "contextid2" on EL2 kernel. Therefore, even without setting "contextid" config, the perf tool can dynamically pick up the config for PID tracing, so the user doesn't have to set the "contexid" config manually. As results, we now have three PMU formats, for easier understanding the implementation, just copy and paste the descriptions for these three PMU formats from the patch 07/07: "contextid1": Available on both EL1 kernel and EL2 kernel. When the kernel is running at EL1, "contextid1" enables the PID tracing; when the kernel is running at EL2, this enables tracing the PID of guest applications. "contextid2": Only usable when the kernel is running at EL2. When selected, enables PID tracing on EL2 kernel. "contextid": Will be an alias for the option that enables PID tracing. I.e, contextid == contextid1, on EL1 kernel. contextid == contextid2, on EL2 kernel. This patch series can be cleanly applied on perf/core branch: commit cd07e536b020 ("Merge remote-tracking branch 'torvalds/master' into perf/core") ... and applied on the mainline kernel: commit 88bb507a74ea ("Merge tag 'media/v5.11-3' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media") The patch series has been tested on Arm Juno-r2 board. Verified the kernel with EL1 and didn't find issue; though absenting the platform for kernel with EL2, after some hacking in kernel driver and tool to emulate the code paths for kernel on EL2, can see the code path is hit without failure. Changes from v1: * Refactored PMU formats, added formats "contextid1"/"contextid2", and reworked format "contextid" (Suzuki/Mathieu); * Refined the comments for perf configs (Leo/Mike); * Added patch 07/07 for description PID tracing in docs; * Found the issue for bitmap for option, extracted patch 03/07 for the fixing. Changes from RFC: * Added comments to clarify cases requested (Leo); * Explain the change to generic flags for cs_etm_set_option() in the commit description; * Stored PID format in metadata and passed it to decoder (Leo); * Enhanced cs-etm for backward compatibility (Denis Nikitin).

[PATCH v4] perf: cs-etm: update ETM metadata format

by Mike Leach

The current fixed metadata version format (version 0), means that adding metadata parameter items renders files from a previous version of perf unreadable. Per CPU parameters appear in a fixed order, but there is no field to indicate the number of ETM parameters per CPU. This patch updates the per CPU parameter blocks to include a NR_PARAMs value which indicates the number of parameters in the block. The header version is incremented to 1. Fixed ordering is retained, new ETM parameters are added to the end of the list. The reader code is updated to be able to read current version 0 files, For version 1, the reader will read the number of parameters in the per CPU block. This allows the reader to process older or newer files that may have different numbers of parameters than in use at the time perf was built. Changes since v3 1. Fixed index bug (Leo) Changes since v2 1. Add error path print to improve --dump logging 2. Replace some hardcoded values with enum consts (Mathieu). Changes since v1 (from Review by Leo): 1. Split printing routine into sub functions per version 2. Renamed NR_PARAMs to NR_TRC_PARAMs to emphasise use as count of trace related parameters, not total block parameter. 3. Misc other fixes.
