[PATCH v2 0/9] OpenCSD - adding ETMv3 decoder patchset.

by Mike Leach

Patchset adds in the ETMv3 instruction trace decoder to the OpenCSD library. ETMv3 tested using the TC2 snapshot. Checked that perf still builds (with associated patch on the perf branch) Checked that the perf example trace decodes for ETMv4 are unaffected. v2 patchset addressing comments from first patch set. Patch relative to arm-dev branch. Mike Leach (9): OCSD response enum value name corrected. ETMv3 packet decoder Refactor etmv3 config class and etmv3 packet class to improve encapsulation. ETMv3 decoder - created code follower generic class. ETMv3 decoder updates. TC2 snapshot update. ETMv3 Decoder Updates - decoder complete.

[PATCH 0/9] Patchset to add ETMv3 instruction decoder.

by Mike Leach

Feature patch set adding the ETMv3 instruction decoder to the main arm-dev branch. Changes add the ETMV3 packet decode objects, along with updates to C-API and test programs This patchset will be applied to the arm-dev trunk unless significant changes are warranted. Stable release branch opencsd-0v003 will then be created. Mike Leach (9): OCSD response enum value name corrected. ETMv3 packet decoder Refactor etmv3 config class and etmv3 packet class to improve encapsulation. ETMv3 decoder - created code follower generic class. ETMv3 decoder updates. TC2 snapshot update.

[PATCH] coresight-stm: support mmapping channel regions with mmio_addr

by Chunyan Zhang

CoreSight STM device allows direct mapping of the channel regions to userspace for zero-copy writing. To support this ability, the STM freamwork has provided a hook 'mmio_addr', this patch just implemented this hook for CoreSight STM. This patch also added an item into 'channel_space' to save the start physical address of channel region which mmap operation needs to know.

[PATCH] Update to perf extensions to fix build with OpenCSD 0v003

by Mike Leach

Additional Generic element type was added in OpenCSD 0v003 (ETMv3 additions) - this broke the perf build as it was missing from the case statement handling the enum types.
