Use alpha value to blend source value and destination value Instead of
just overwrite with source value.

These could all live in a tighter scope.
Apart from that lgtm

Hi, Ville.
Thank you for reviewing my patch.
I think that's good idea and I'll do that in next version.
I found some patch in mailing list that is similar with this patch.
So should I drop this patch and find other thing?

Probably best if you discuss that with whoever sent that other patch.

Hi Sidong,
Thanks a lot for your patch and effort to improve VKMS.

Did you test your change with IGT? Maybe I missed something but looks
like that you're applying the alpha value but the value that we get is
already pre-multiplied.
Btw, It looks like that you and Melissa are working in the same feature,
maybe you two could try to sync for avoiding overlapping.
Finally, do you have plans to send your fix for
vkms_get_vblank_timestamp() function? That patch was really good and
removes a lot of warning generated during the IGT test.
Best Regards

Thanks for review.
Yes, this patch should be dropped and I should watch Melissa's patch.

Okay, I'll work for improve vkms_get_vblank_timestamp().
