Hi,
Set of patches for a new plane property FB_DAMAGE_CLIPS to send damage during plane update. I have incorporated review comments since last RFC. Also with this patch series vmwgfx implementation of plane damage.
Based on Rob Clark earlier patch, implemented legacy dirtyfb with new damage clips property.
I will be sending a separate patch series for unit test case for damage interface using igt-gpu-tools. Also a separate patch series for a rudimentary weston implementation, which for now only send damage for default scanout plane.
Testing: vmware xorg driver mainly use dirty_fb ioctl to update the screen so it is a good overall test of damage interface. Weston implementation also works as intended.
Let me know what you think. Thanks, Deepak
