drm/amd: use list_for_each_entry for list iteration.

2020-01-07T17:04:16Z

list_for_each() can be replaced by the more concise list_for_each_entry() here for iteration over the lists. This change was reported by coccinelle. Signed-off-by: Wambui Karuga Signed-off-by: Alex Deucher

drm/amdgpu: Iterate through DRM connectors correctly

2019-10-03T14:11:05Z

Currently, every single piece of code in amdgpu that loops through connectors does it incorrectly and doesn't use the proper list iteration helpers, drm_connector_list_iter_begin() and drm_connector_list_iter_end(). Yeesh. So, do that. Cc: Juston Li Cc: Imre Deak Cc: Ville Syrjälä Cc: Harry Wentland Cc: Daniel Vetter Reviewed-by: Alex Deucher Signed-off-by: Lyude Paul Signed-off-by: Alex Deucher

drm/amd/display: Delete a redundant memory setting in amdgpu_dm_irq_register_interrupt()

2019-06-17T16:02:03Z

The memory was set to zero already by a call of the function “kzalloc”. Thus remove an extra call of the function “memset” for this purpose. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Alex Deucher

drm/amd/display: In VRR mode, do DRM core vblank handling at end of vblank. (v2)

2019-04-03T15:00:33Z

In VRR mode, proper vblank/pageflip timestamps can only be computed after the display scanout position has left front-porch. Therefore delay calls to drm_crtc_handle_vblank(), and thereby calls to drm_update_vblank_count() and pageflip event delivery, to after the end of front-porch when in VRR mode. We add a new vupdate irq, which triggers at the end of the vupdate interval, ie. at the end of vblank, and calls the core vblank handler function. The new irq handler is not executed in standard non-VRR mode, so vblank handling for fixed refresh rate mode is identical to the past implementation. v2: Implement feedback by Nicholas and Paul Menzel.

drm/amd/display: Initial documentation for AMDgpu DC

2018-11-05T19:21:37Z

[Why] Documentation is helpful for the community to understand our code. This change does some high-level documentation of some DM interfaces with DRM, and the amdgpu base driver. [How] An entry for AMDgpu DC has been added to Documentation/gpu/drivers.rst TOC. amdgpu-dc.rst is created to pull in inline doc-strings, which: - Provides an overview for "What is DM?" - Documents AMDgpu DM lifecyle - Documents IRQ management - Documents atomic_check and commit_tail interfaces Signed-off-by: Leo Li Reviewed-by: David Francis Acked-by: Leo Li Signed-off-by: Alex Deucher
