Patch 1 adds the qcom_gpi trace events header (private to the driver, in drivers/dma/qcom/gpi_trace.h) and wires the tracepoints into the driver alongside the existing dev_dbg() calls. Patch 2 converts the remaining dev_dbg() call sites in the driver to use the new tracepoints instead. Signed-off-by: Praveen Talari --- Changes in v3: - Move the qcom_gpi trace events header from include/trace/events/qcom_gpi.h into drivers/dma/qcom/gpi_trace.h, since it has no users outside the GPI DMA driver, and squash it into the tracepoint-wiring patch. - Drop the redundant per-function breakdown paragraph from the dev_dbg()-to-tracepoint conversion patch; the first paragraph already describes the change. - Link to v2: https://patch.msgid.link/20260909-add-trace-support-gpio-v2-0-01f81739bb88@oss.qualcomm.com Changes in v2: - Reorder TP_STRUCT__entry() fields in gpi_ev_process, gpi_alloc_ring, and gpi_ring_info to avoid holes: 8/16-bit fields moved to the end, and 64-bit/size_t fields moved before the __string() field (treating __string() as 4 bytes of metadata).
