drm/amdgpu: switch to drm_*{get,put} helpers

2017-08-15T18:46:12Z

drm_*_reference() and drm_*_unreference() functions are just compatibility alias for drm_*_get() and drm_*_put() and should not be used by new code. So convert all users of compatibility functions to use the new APIs. Reviewed-by: Christian König Signed-off-by: Cihangir Akturk Signed-off-by: Alex Deucher

drm: amd: remove dead code and pointless local lut storage

2017-08-04T09:35:15Z

The redundant fb helpers .load_lut, .gamma_set and .gamma_get are no longer used. Remove the dead code and hook up the crtc .gamma_set to use the crtc gamma_store directly instead of duplicating that info locally.

drm/: Drop fbdev info flags

2017-07-26T11:22:40Z

- FBINFO_CAN_FORCE_OUTPUT has been a lie ever since we nerfed&removed the entire panic handling code in our fbdev emulation. We might restore kms panic output, but not through the bazillion of legacy code layers called fbdev/fbcon, there's just no way to make that work safely. - With the module check change FBINFO_DEFAULT is always 0, so can be removed too. That removes another change to cargo-cult stuff in kms drivers, yay!

drm: Rely on mode_config data for fb_helper initialization

2017-02-02T18:12:00Z

Instead of receiving the num_crts as a parameter, we can read it directly from the mode_config structure. I audited the drivers that invoke this helper and I believe all of them initialize the mode_config struct accordingly, prior to calling the fb_helper. I used the following coccinelle hack to make this transformation, except for the function headers and comment updates. The first and second rules are split because I couldn't find a way to remove the unused temporary variables at the same time I removed the parameter. // @r@ expression A,B,D,E; identifier C; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ expression A,B,C,D,E; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ identifier r.C; type T; expression V; @@ - T C; <... when != C - C = V; ...> // Changes since v1: - Rebased on top of the tip of drm-misc-next. - Remove mention to sti since a proper fix got merged.
