drm/tinydrm: Use DRM_GEM_CMA_VMAP_DRIVER_OPS

2018-11-20T13:58:19Z

The CMA helper now has the functionality to ensure a virtual address on imported buffer so use that. While touching all tinydrm drivers, remove the unnecessary inclusion of drm_fb_helper.h in some drivers.

drm/tinydrm: Advertise that we can do only DRM_FORMAT_MOD_LINEAR.

2018-10-30T20:01:50Z

Without this, the xserver relies on what the 3D driver exposes and assumes that the display can handle it, and then the DRM driver happily tries to scan out a tiled format.

drm/tinydrm: Replace drm_dev_unref with drm_dev_put

2018-08-07T15:09:15Z

This patch unifies the naming of DRM functions for reference counting of struct drm_device. The resulting code is more aligned with the rest of the Linux kernel interfaces.

drm/tinydrm: Use gem_free_object_unlocked

tinydrm doesn't use dev->struct_mutex and therefore has no need to use gem_free_object. Signed-off-by: Daniel Vetter Cc: "Noralf Trønnes" Acked-by: Noralf Trønnes Link: https://patchwork.freedesktop.org/patch/msgid/20180322105133.11211-2-daniel.vetter@ffwll.ch

drm/tinydrm: Use drm_fb_cma_fbdev_init_with_funcs/fini()

2017-12-10T14:37:07Z

Use drm_fb_cma_fbdev_init_with_funcs() and drm_fb_cma_fbdev_fini() which relies on the fact that drm_device holds a pointer to the drm_fb_helper structure. This means that the driver doesn't have to keep track of that. Also use the drm_fb_helper functions directly. Remove todo entry.

drm/atomic: Introduce drm_atomic_helper_shutdown

2017-03-27T07:43:58Z

The trouble here is that it does multiple atomic commits under one drm_modeset_lock_all, which breaks the behind-the-scenes acquire context magic that function pulls off. It's much better to have one overall atomic commit. That we still have multiple atomic commits prevents us from adding some pretty useful debug checks to the atomic machinery. Hence it is really a bad idea to call the legacy drm_crtc_force_disable_all() function. There's 2 atomic drivers using this still, nouveau and tinydrm. To fix this, introduce a new drm_atomic_helper_shutdown() by extracting the code from i915. While at it improve kernel-doc and catch future offenders by sprinkling a WARN_ON into the legacy function. We should probably move those into the legacy modeset helpers, too ... v2: Make it compile on arm drivers too (Noralf). v3: Correct kerneldoc to point at _disable_all().
