[PATCH v3 3/6] coresight: Support panic kdump functionality

After kernel panic happens, coresight has many useful info can be used for analysis. For example, the trace info from ETB RAM can be used to check the CPU execution flows before crash. So we can save the tracing data from sink devices, and rely on kdump to save DDR content and uses "crash" tool

[PATCH v3 6/6] coresight: etm4x: Support panic kdump

ETMv4 hardware information and configuration needs to be saved as metadata; these metadata should be compatible with tool 'perf' and can be used for tracing data analysis. ETMv4 usually works as tracer per CPU, we cannot wait to gather ETM info after the CPU has been panic and cannot execute dump

[PATCH v3 4/6] coresight: tmc: Hook callback for panic kdump

Since the panic kdump functionality has been ready, this patch is to hook panic callback function for ETB/ETF. Since the driver data structure has allocated buffer when the session started, so simply save ETB/ETF trace data into the buffer when panic happens and update related info into dump

[PATCH v3 5/6] coresight: Add and delete sink callback for panic kdump list

If the sink device has panic kdump callback, this means the sink device wants to save tracing data for panic happening. This commit adds node into panic kdump list when the sink device is enabled, and delete node when the sink device is disabled. Signed-off-by: Leo Yan ---

[PATCH v3 0/6] Coresight: support panic kdump

This patch set is to explore Coresight trace data for postmortem debugging. When kernel panic happens, the Coresight panic kdump can help save on-chip trace data and tracer metadata into DRAM, later relies on kdump and crash/perf for "offline" analysis. The documentation is important to
