Display dma_fence events in a single row about perfetto HOT 2 OPEN

Yes it's possible to make the change within trace processor: you just need to change the code at https://cs.android.com/android/platform/superproject/main/+/main:external/perfetto/src/trace_processor/importers/ftrace/drm_tracker.cc;bpv=1

Patches to fix this welcome (contribution guide is available at https://perfetto.dev/docs/contributing/getting-started) but it's likely not something we will get to ourselves soon.

Thanks for the code link. I think I misunderstood the track name format in the issue description. According to GetFenceTimelineByContext, what I assumed to be seqno (number at the end of the track name) were actually contexts. It's probably something specific to the driver I'm investigating to increment contexts for each fence. I'll study this a bit more (might take a while).
