This doesn't make much sense, the cursor overlay is really just a hint for legacy ioctls that this is the overlay that should be used for cursors. Compositors should try to use such planes as full overlays (if they don't want to use them as a cursor). So sounds like a case of "fix your compositor". For atomic there's 0 difference between a overlay or a cursor (primary plane is still treated somewhat special in the RMFB ioctl, but again that's for backwards compat reasons with existing uapi, not because the primary plane is different). What does happen though is that this breaks cursor for legacy userspace, which is probably not really what you want. -Daniel > > Regards, > Alex > > Changes in v2: > - drop not yet upstreamed dsp_data_swap from RK3188 regs > - rephrase most commit messages > > Alex Bee (5): > drm: rockchip: add scaling for RK3036 win1 > drm: rockchip: add missing registers for RK3188 > drm: rockchip: add alpha support for RK3036, RK3066, RK3126 and RK3188 > drm: rockchip: set alpha_en to 0 if it is not used > drm: rockchip: use overlay windows as such > > drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 1 + > drivers/gpu/drm/rockchip/rockchip_vop_reg.c | 42 ++++++++++++++++++--- > drivers/gpu/drm/rockchip/rockchip_vop_reg.h | 1 + > 3 files changed, 38 insertions(+), 6 deletions(-) > > -- > 2.17.1 > -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
