2020-10-26drm/amd/display: Decouple amdgpu_dm_trace from serviceRodrigo Siqueira1-6/+11
Our DC currently uses some of the tracepoint function inside a DC header, which means that many other files implicitly include part of the trace function. This situation limits how we can expand this feature for other parts of the driver by generating multiple compilation errors when we try to reuse some of the existing structures. This commit decouples part of the amdgpu_dm_trace from DC core to simplify the trace enlargement in future changes.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter1-1/+1
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.
