f78d206f - Coresight: Add Coresight TMC Control Unit driver

Mon, 03 Mar 2025 03:29:30 +0000

Coresight: Add Coresight TMC Control Unit driverThe Coresight TMC Control Unit hosts miscellaneous configuration registerswhich control various features related to TMC ETR sink.Based on the trace ID, which is programmed in the related CTCU ATIDregister of a specific ETR, trace data with that trace ID gets intothe ETR buffer, while other trace data gets dropped.Enabling source device sets one bit of the ATID register based onsource device's trace ID.Disabling source device resets the bit according to the sourcedevice's trace ID.Reviewed-by: James Clark Signed-off-by: Jie Gan Signed-off-by: Suzuki K Poulose Link: https://lore.kernel.org/r/20250303032931.2500935-10-quic_jiegan@quicinc.com List of files: /linux-6.15/drivers/hwtracing/coresight/Makefile

d999c7dd - coresight: Make current W=1 warnings default

Thu, 23 Nov 2023 12:04:59 +0000

coresight: Make current W=1 warnings defaultSimilarly to drivers/gpu/drm/amd/amdgpu/Makefile andfs/btrfs/Makefile, copy the current set of W=1 warnings fromMakefile.extrawarn to the coresight makefile to make them default.Unfortunately there is no easy way to do this without copying.In addition to the default set of warnings, add -Wno-sign-compare todisable that warning. That's because Makefile.extrawarn does some extrasteps to disable some -Wextra warnings unless W=2 or W=3 are used.That's the only one that's needed for Coresight, so disable it.Signed-off-by: James Clark Signed-off-by: Suzuki K Poulose Link: https://lore.kernel.org/r/20231123120459.287578-5-james.clark@arm.com List of files: /linux-6.15/drivers/hwtracing/coresight/Makefile

9d3ba0b6 - Coresight: Add coresight dummy driver

Fri, 02 Jun 2023 08:41:47 +0000

Coresight: Add coresight dummy driverSome Coresight devices that kernel don't have permission to access orconfigure. For these devices, a dummy driver is needed to register them asCoresight devices. The module may also be used to define components thatmay not have any programming interfaces, so that paths can be createdin the driver. It provides Coresight API for operations on dummy devices,such as enabling and disabling them. It also provides the Coresight dummysink/source paths for debugging.Signed-off-by: Hao Zhang Signed-off-by: Suzuki K Poulose Link: https://lore.kernel.org/r/20230602084149.40031-2-quic_hazha@quicinc.com List of files: /linux-6.15/drivers/hwtracing/coresight/Makefile

338a588e - coresight: trace-id: Add API to dynamically assign Trace ID values

Mon, 16 Jan 2023 12:49:14 +0000

coresight: trace-id: Add API to dynamically assign Trace ID valuesThe existing mechanism to assign Trace ID values to sources is limitedand does not scale for larger multicore / multi trace source systems.The API introduces functions that reserve IDs based on availabiltyrepresented by a coresight_trace_id_map structure. This records theused and free IDs in a bitmap.CPU bound sources such as ETMs use the coresight_trace_id_get_cpu_idcoresight_trace_id_put_cpu_id pair of functions. The API will recordthe ID associated with the CPU. This ensures that the same ID will bere-used while perf events are active on the CPU. The put_cpu_id functionwill pend release of the ID until all perf cs_etm sessions are complete.For backward compatibility the functions will attempt to use the sameCPU IDs as the legacy system would have used if these are still available.Non-cpu sources, such as the STM can use coresight_trace_id_get_system_id /coresight_trace_id_put_system_id.Signed-off-by: Mike Leach [ Fix checkpatch warning in drivers/hwtracing/coresight/coresight-trace-id.c ]Signed-off-by: Suzuki K Poulose Link: https://lore.kernel.org/r/20230116124928.5440-2-mike.leach@linaro.org List of files: /linux-6.15/drivers/hwtracing/coresight/Makefile

3fbf7f01 - coresight: sink: Add TRBE driver

Mon, 05 Apr 2021 16:43:04 +0000

coresight: sink: Add TRBE driverTrace Buffer Extension (TRBE) implements a trace buffer per CPU which isaccessible via the system registers. The TRBE supports different addressingmodes including CPU virtual address and buffer modes including the circularbuffer mode. The TRBE buffer is addressed by a base pointer (TRBBASER_EL1),an write pointer (TRBPTR_EL1) and a limit pointer (TRBLIMITR_EL1). But theaccess to the trace buffer could be prohibited by a higher exception level(EL3 or EL2), indicated by TRBIDR_EL1.P. The TRBE can also generate a CPUprivate interrupt (PPI) on address translation errors and when the bufferis full. Overall implementation here is inspired from the Arm SPE driver.Cc: Mathieu Poirier Cc: Mike Leach Cc: Suzuki K Poulose Signed-off-by: Anshuman Khandual [ Mark the buffer truncated on WRAP event, error code cleanup ]Signed-off-by: Suzuki K Poulose Link: https://lore.kernel.org/r/20210405164307.1720226-18-suzuki.poulose@arm.comSigned-off-by: Mathieu Poirier List of files: /linux-6.15/drivers/hwtracing/coresight/Makefile
