some trace event use an interger to to save a bit field info of gadget, also some trace save endpoint name in string forat, it all can be chagned to other way at trace event store phase. bit field can be replace with a union interger member which include multiple bit fields. ep name stringe can be replace to a interger which contaion number and dir info. to allow trace output stage can get bit info from save interger, add DECLARE_EVENT_CLASS_PRINT_INIT() clas which allow user defined operation before print. v1: https://lore.kernel.org/linux-usb/20230911042843.2711-1-quic_linyyuan@xxxxxxxxxxx/ v2: fix two compile issues that COMPILE_TEST not covered https://lore.kernel.org/linux-usb/20230911112446.1791-1-quic_linyyuan@xxxxxxxxxxx/ v3: fix reviewer comments, allow bit fields work on both little and big endian https://lore.kernel.org/linux-usb/20230912104455.7737-1-quic_linyyuan@xxxxxxxxxxx/ v4: add DECLARE_EVENT_CLASS_PRINT_INIT() new trace class and use it Linyu Yuan (8): trace: add new DECLARE_EVENT_CLASS_PRINT_INIT class type usb: gadget: add anonymous definition in some struct for trace purpose usb: udc: trace: reduce buffer usage of trace event usb: cdns3: trace: reduce buffer usage of trace event usb: dwc3: trace: reduce buffer usage of trace event usb: cdns2: trace: reduce buffer usage of trace event usb: mtu3: trace: reduce buffer usage of trace event usb: musb: trace: reduce buffer usage of trace event drivers/usb/cdns3/cdns3-trace.h | 201 ++++++++++++++------- drivers/usb/cdns3/cdnsp-trace.h | 105 +++++++---- drivers/usb/dwc3/trace.h | 99 ++++++---- drivers/usb/gadget/udc/cdns2/cdns2-trace.h | 175 ++++++++++++------ drivers/usb/gadget/udc/trace.h | 154 +++++++--------- drivers/usb/mtu3/mtu3_trace.h | 76 +++++--- drivers/usb/musb/musb_trace.h | 20 +- include/linux/tracepoint.h | 22 +++ include/linux/usb/gadget.h | 113 +++++++----- include/trace/bpf_probe.h | 4 + include/trace/perf.h | 43 +++++ include/trace/stages/stage3_trace_output.h | 3 + include/trace/trace_events.h | 118 ++++++++++++ 13 files changed, 784 insertions(+), 349 deletions(-) -- 2.17.1
