[PATCH v3 15/20] drm/dp_dual_mode: Pass drm_device to drm_lspcon_(get|set)_mode()

[PATCH v3 11/20] drm/dp_dual_mode: Pass drm_device to drm_dp_dual_mode_detect()

Since we're about to be using drm_dbg_*() throughout the DP helpers, we'll need to be able to access the DRM device in the dual mode DP helpers as well. Note however that since drm_dp_dual_mode_detect() can be called with DDC adapters that aren't part of a drm_dp_aux struct, we need to pass down th

[PATCH v3 17/20] drm/print: Handle potentially NULL drm_devices in drm_dbg_*

While this shouldn't really be something that happens all that often, since we're going to be using the drm_dbg_* log helpers in DRM helpers it's technically possible that a driver could use an AUX adapter before it's been associated with it's respective drm_device. While drivers should take care t

[PATCH v3 18/20] drm/dp: Convert drm_dp_helper.c to using drm_err/drm_dbg_*()

Now that we've added a back-pointer to drm_device to drm_dp_aux, made drm_dp_aux available to any functions in drm_dp_helper.c which need to print to the kernel log, and ensured all of our logging uses a consistent format, let's do the final step of the conversion and actually move everything over

[PATCH v3 16/20] drm/dp_mst: Pass drm_dp_mst_topology_mgr to drm_dp_get_vc_payload_bw()

Since this is one of the few functions in drm_dp_mst_topology.c that doesn't have any way of getting access to a drm_device, let's pass the drm_dp_mst_topology_mgr down to this function so that it can use drm_dbg_kms(). Signed-off-by: Lyude Paul --- drivers/gpu/drm/drm_dp_mst_topology.c |

[PATCH v3 19/20] drm/dp_dual_mode: Convert drm_dp_dual_mode_helper.c to using drm_err/drm_dbg_kms()

Next step in the conversion, move everything in drm_dp_dual_mode_helper.c over to using drm_err() and drm_dbg_kms(). This was done using the following cocci script: @@ expression list expr; @@ ( - DRM_DEBUG_KMS(expr); + drm_dbg_kms(dev, expr); | - DRM_ERROR(expr); + drm_err(dev,

[PATCH v3 20/20] drm/dp_mst: Convert drm_dp_mst_topology.c to drm_err()/drm_dbg*()

And finally, convert all of the code in drm_dp_mst_topology.c over to using drm_err() and drm_dbg*(). Note that this refactor would have been a lot more complicated to have tried writing a coccinelle script for, so this whole thing was done by hand. v2: * Fix line-wrapping in drm_dp_mst_atomic_che

Re: [RFC] Linux Graphics Next: Explicit fences everywhere and no BO fences - initial proposal

We already don't have accurate BO fences in some cases. Instead, BOs can have fences which are equal to the last seen command buffer for each queue. It's practically the same as if the kernel had no visibility into command submissions and just added a fence into all queues when it needed to wait fo
