Re: [PATCH] drm/vkms: Optimize compute_crc(), blend()
Hi, First of all, thanks a lot for all your patch. And thanks Emil for your feedback. I have a suggestion here: Emil: Could you give me your Acked-by or maybe Reviewed-by for the writeback series? With that, I can finally apply the series. Sidong: Secondly, after applying the writeback series, I would suggest you to understand Emil's comments (he already provides the link) and prepare a new patch based on that. Before you submit your patch, I recommend you to test it with https://patchwork.freedesktop.org/series/68352/ and kms_flip. How about that?

If there are - mentioned them in the commit message. Otherwise, it doesn't optimise anything. A while back, I've suggested something similar [1] mostly for cosmetic purposes - doubt there's much benefits beyond that.
