eb_fb_blit should be able to blit partial image of guest display (blob res) in case multiple displays are configured for the guest and they are set as extended- desktop mode. v2: egl_fb includes dmabuf info then make egl_fb_blit position and size parameters programmed in dmabuf structure (previously position/size parameters were given to egl_fb_blit separately) (Vivek Kasireddy) changed the commit message as there is no interface change to egl_fb_blit Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Vivek Kasireddy <vivek.kasireddy@intel.com> Signed-off-by: Dongwon Kim <dongwon.kim@intel.com> --- ui/egl-helpers.c | 25 +++++++++++++++++++++---- 1 file changed, 21 insertions(+), 4 deletions(-)
