2015-07-13drm/rockchip: vop: remove hardware cursor windowyao mark1-11/+0
hardware cursor windows only have some fixed size, and not support width virtual, when move hardware cursor windows outside of left, the display would be wrong, so this window can't for cursor now. And Tag hardware cursor window as a overlay is wrong, will make userspace wrong behaviour. So just remove the hardware cursor window Signed-off-by: Mark Yao <mark.yao@rock-chips.com>

2015-07-13drm/rockchip: use drm_gem_mmap helpersDaniel Kurtz1-33/+34
Rather than (incompletely [0]) re-implementing drm_gem_mmap() and drm_gem_mmap_obj() helpers, call them directly from the rockchip mmap routines. Once the core functions return successfully, the rockchip mmap routines can still use dma_mmap_attrs() to simply mmap the entire buffer. [0] Previously, we were performing the mmap() without first taking a reference on the underlying gem buffer. This could leak ptes if the gem object is destroyed while userspace is still holding the mapping.

2015-07-13drm/rockchip: only call drm_fb_helper_hotplug_event if fb_helper presentHeiko Stübner1-1/+2
Add a check for the presence of fb_helper to rockchip_drm_output_poll_changed() to only call drm_fb_helper_hotplug_event if there is actually a fb_helper available. Without this check I see NULL pointer dereferences when the hdmi hotplug irq fires before the fb_helper got initialized. Signed-off-by: Heiko Stuebner <heiko@sntech.de>

there is a Bug that: vop_enable()->drm_vblank_on, drm_vblank_on may call vop enable vblank. if it happen, vblank enable would failed, then cause irq status error. because is_enabled value is set after drm_vblank_on. after enable vop clocks and iommu regs, we can sure that R/W vop regs and do vop plane flip is safe, so place is_enabled = true after enable iommu is suitable.

2015-03-16drm/rockchip: Only alloc a kmap for fbdev gem objectDaniel Kurtz3-7/+15
In general, the data in drm/rockchip GEM objects is never accessed by the kernel. The objects are either accessed by a GPU, by display controller DMA, or by mmap'ing them to user space. Thus, these buffers need not be mapped into kernel address space. The only exception is the fbdev framebuffer(s), which may be written in-kernel by fbcon.
