Eric Auger 5c08600547 vfio: Use a trace point when a RAM section cannot be DMA mapped ... Commit 567b5b309a ("vfio/pci: Relax DMA map errors for MMIO regions") added an error message if a passed memory section address or size is not aligned to the page size and thus cannot be DMA mapped. This patch fixes the trace by printing the region name and the memory region section offset within the address space (instead of offset_within_region). We also turn the error_report into a trace event. Indeed, In some cases, the traces can be confusing to non expert end-users and let think the use case does not work (whereas it works as before). This is the case where a BAR is successively mapped at different GPAs and its sections are not compatible with dma map. The listener is called several times and traces are issued for each intermediate mapping. The end-user cannot easily match those GPAs against the final GPA output by lscpi. So let's keep those information to informed users. In mid term, the plan is to advise the user about BAR relocation relevance.
