[PATCH 09/17] coresight: Convert driver messages to dev_dbg

19 Oct 2017 10:20:13 -0800

Convert component enable/disable messages from dev_info to dev_dbg. This is required to prevent LOCKDEP splats when operating in perf mode where we co

[PATCH 11/17] coresight etr: Handle driver mode specific ETR buffers

19 Oct 2017 10:20:13 -0800

Since the ETR could be driven either by SYSFS or by perf, it becomes complicated how we deal with the buffers used for each of these modes. The ETR dr

[PATCH 10/17] coresight: etr: Track if the device is coherent

19 Oct 2017 10:20:13 -0800

Track if the ETR is dma-coherent or not. This will be useful in deciding if we should use software buffering for perf. Cc: Mathieu Poirier

[PATCH 07/17] coresight: tmc etr: Add transparent buffer management

19 Oct 2017 10:20:13 -0800

At the moment we always use contiguous memory for TMC ETR tracing when used from sysfs. The size of the buffer is fixed at boot time and can only be c

[PATCH 08/17] coresight: tmc: Add configuration support for trace buffer size

19 Oct 2017 10:20:13 -0800

Now that we can dynamically switch between contiguous memory and SG table depending on the trace buffer size, provide the support for selecting an app

[PATCH 06/17] coresight: tmc: Make ETR SG table circular

19 Oct 2017 10:20:13 -0800

Make the ETR SG table Circular buffer so that we could start at any of the SG pages and use the entire buffer for tracing. This can be achieved by :

[PATCH 04/17] coresight: Add generic TMC sg table framework

19 Oct 2017 10:20:13 -0800

This patch introduces a generic sg table data structure and associated operations. An SG table can be used to map a set of Data pages where the trace

[PATCH 15/17] coresight: etr_buf: Add helper for padding an area of trace data

19 Oct 2017 10:20:12 -0800

This patch adds a helper to insert barrier packets for a given size (aligned to packet size) at given offset in an etr_buf. This will be used later fo

[PATCH 13/17] coresight etr: Do not clean ETR trace buffer

19 Oct 2017 10:20:12 -0800

We zero out the entire trace buffer used for ETR before it is enabled, for helping with debugging. Since we could be restoring a session in perf mode,

[PATCH 14/17] coresight: etr: Add support for save restore buffers

19 Oct 2017 10:20:12 -0800

Add support for creating buffers which can be used in save-restore mode (e.g, for use by perf). If the TMC-ETR supports save-restore feature, we could
