[PATCH 0/3] dmaengine: qcom: gpi: Add trace event support
From: Praveen Talari
Date: Mon Aug 31 2026 - 17:37:20 EST
This series adds tracepoint support to the Qualcomm GPI DMA engine
driver, giving structured runtime visibility into GPI DMA behavior
without requiring invasive debug patches.
Patch 1 adds the qcom_gpi trace events header, covering command
dispatch, IRQ handling, channel/event control state transitions,
completion event processing, ring allocation, and TRE contents.
Patch 2 wires these tracepoints into the driver alongside the
existing dev_dbg() calls.
Patch 3 converts the remaining dev_dbg() call sites in the driver to
use the new tracepoints instead.
