Allow combining DBG and WPP by defining DBG and EVENT_TRACING at the same time.

@akihikodaki I have a question (just a question): What is the motivation to define both DBG and WPP?

@akihikodaki @ybendito Yeah, I also have the same question :) IIRC, the original intention was to enable WPP in release builds and keep DBG for the developers, if they need it. Did we change this approach recently?

All the best, Vadim.

@ybendito @vrozenfe My use case is to debug a detached Arm64 system.

Setting DBG gives logs via COM or vDbgPrintEx and enables debug assertions using VIOGPU_ASSERT_CHK. The logging does not work for a detached Arm64 system because:

  • IO ports used for COM are not available on Arm64.
  • vDbgPrintEx works only when attached.

Combining DBG and WPP allows having logging and debug assertions at the same time on a detached Arm64 system.
