[PATCH 0/2] hwtracing: hisi_ptt: Fix reset timeout handling and clean up trace start

Posted by Pradhan, Sanman 2 months, 1 week ago

From: Sanman Pradhan <psanman@juniper.net>

Patch 1: Propagate the DMA reset timeout error from
  hisi_ptt_wait_dma_reset_done() instead of discarding it. Move
  ctrl->started to the successful path so a failed start does not leave
  the trace marked as active.

Patch 2: Remove the unnecessary 16 MiB memset of trace buffers in
  hisi_ptt_trace_start(). The driver only copies data that hardware has
  written, so the zeroing is not needed.

    trace_start()
