stm class: ftrace: Use different channel accroding to CPU

2020-10-05T10:43:54Z

To avoid mixup of packets from differnt ftrace packets simultaneously, use different channel for packets from different CPU.

stm class: ftrace: Change dependency to TRACING

2020-10-05T10:43:53Z

We will support copying event trace to STM. Change STM_SOURCE_FTRACE to depend on TRACING since we will support multiple tracers.

coresight: etm4x: Fix save and restore of TRCVMIDCCTLR1 register

2020-09-28T17:47:42Z

In commit f188b5e76aae ("coresight: etm4x: Save/restore state across CPU low power states"), mistakenly TRCVMIDCCTLR1 register value was saved in trcvmidcctlr0 state variable which is used to store TRCVMIDCCTLR0 register value in etm4x_cpu_save() and then same value is written back to both TRCVMIDCCTLR0 and TRCVMIDCCTLR1 in etm4x_cpu_restore(). There is already a trcvmidcctlr1 state variable available for TRCVMIDCCTLR1, so use it.

coresight: core: Allow the coresight core driver to be built as a module

2020-09-28T17:47:42Z

Enhance coresight developer's efficiency to debug coresight drivers. - Kconfig becomes a tristate, to allow =m - append -core to source file name to allow module to be called coresight by the Makefile - modules can have only one init/exit, so we add the etm_perf register/unregister function calls to the core init/exit functions. - add a MODULE_DEVICE_TABLE for autoloading on boot Cc: Mathieu Poirier Cc: Leo Yan Cc: Alexander Shishkin Cc: Randy Dunlap Cc: Suzuki K Poulose Cc: Greg Kroah-Hartman Cc: Russell King Tested-by: Mike Leach Reviewed-by: Suzuki K Poulose Signed-off-by: Kim Phillips Signed-off-by: Tingwei Zhang Signed-off-by: Mathieu Poirier Link: https://lore.kernel.org/r/20200928163513.70169-25-mathieu.poirier@linaro.org Signed-off-by: Greg Kroah-Hartman

2020-09-28T17:47:42Z

Make etr_catu_buf_ops static. Instead of directly accessing it in etr_buf_ops[], add a function to let catu driver register the ops at runtime. Break circular dependency between tmc-etr and catu drivers.
