drm/rockchip: respect CONFIG_DRM_FBDEV_EMULATION

2016-01-22T00:45:31Z

If DRM_FBDEV_EMULATION is not selected in the config then we can save a bit of space by not including the framebuffer code. Signed-off-by: John Keeping

drm/rockchip: fix wrong pitch/size using on gem

2016-01-21T01:14:05Z

args->pitch and args->size may not be set by userspace, sometimes userspace only malloc args and not memset args to zero, then args->pitch and args->size is random, it is very danger to use pitch/size on gem. pitch's type is u32, and min_pitch's type is int, example, pitch is 0xffffffff, then pitch < min_pitch return true, then gem will alloc very very big bufffer, it would eat all the memory and cause kernel crash. Stop using pitch/size from args, calc them from other args. Signed-off-by: Mark Yao

drm/rockchip: don't wait for vblank if fb hasn't changed

2016-01-20T00:55:56Z

As commented in drm_atomic_helper_wait_for_vblanks(), userspace relies on cursor ioctls being unsynced. Converting the rockchip driver to atomic has significantly impacted cursor performance by making every cursor update wait for vblank. By skipping the vblank sync when the framebuffer has not changed (as is done in drm_atomic_helper_wait_for_vblanks()) we can avoid this for the common case of moving the cursor and only need to delay the cursor ioctl when the cursor icon changes. We cannot add the check on legacy_cursor_update since that results in the cursor bo being unreferenced while the hardware may still be reading it. Fully supporting unsynced cursor updates is left for the future when the atomic helper framework supports async updates. Signed-off-by: John Keeping Tested-by: Heiko Stuebner

drm/rockchip/dsi: fix handling mipi_dsi_pixel_format_to_bpp result

2016-01-18T00:43:16Z

The function can return negative value so it should be assigned to signed variable. The problem has been detected using patch scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci. Signed-off-by: Andrzej Hajda Reviewed-by: Chris Zhong

drm/rockchip: vop: fix mask when updating interrupts

2016-01-18T00:42:09Z

Commit dbb3d94 (drm/rockchip: vop: move interrupt registers into vop_data) introduced new macros for updating the interrupt control registers but these always use the mask from the register definition without refining it for the particular bits that are being changed. This means that whenever we enable/disable a particular interrupt we end up disabling all of the others as a side effect. Signed-off-by: John Keeping

drm/rockchip: cleanup unnecessary export symbol

2016-01-18T00:42:09Z

Now rockchip_drm_vop.c is build into rockchipdrm.ko, so no need to export following symbol anymore: rockchip_drm_dma_attach_device rockchip_drm_dma_detach_device rockchip_drm_dma_attach_device rockchip_drm_dma_detach_device rockchip_register_crtc_funcs rockchip_unregister_crtc_funcs rockchip_fb_get_gem_obj Signed-off-by: Mark Yao

drm/rockchip: Don't build rockchip_drm_vop as modules

2016-01-18T00:42:08Z

rockchip_drm_vop's module init had moved to rockchip_vop_reg.c so no need to build rockchip_drm_vop.ko Signed-off-by: Mark Yao

drm/rockchip: return a true clock rate to adjusted_mode

2016-01-06T05:51:09Z

Since the mipi dsi driver need to use the clock of vop to make the calculation of Blanking. But sometimes the clock driver can not set a accurate clock_rate for vop, get it by clk_round_rate before mode_set, so we can get the true value. Signed-off-by: Chris Zhong Acked-by: Mark Yao
