Eh, there are a fair number of differences between the MDSS versions for 8998 and 845. Probably a bigger question, why extend the DPU driver for 8998, when the MDP5 driver already supports it[1]? The MDP/DPU split is pretty dumb, but I don't see a valid reason for both drivers supporting the same target/display revision. IMO, if you want this support in DPU, remove it from MDP5.

Having support both in MDP5 and DPU would allow one to compare those two drivers, performance, features, etc. It might be that all MDP5-supported hardware would be also supported by DPU, thus allowing us to remove the former driver. But until that time I'd suggest leaving support in place.

Yep, the DT issue wasn't thought about from my side at the review time. I considered qcom,msm8998-dpu as an extension/upgrade of bare qcom,mdp5 compatibility string (as we usually add chip-specific compatibilities). In fact using just 'qcom,mdp5' prevents us from having such kind of driver upgrades. What I'd propose if everybody else agrees on moving 8998 (and maybe others later) from MDP5 to DPU would be to continue supporting qcom,mdp5 binding in the mdp5 driver and to add qcom,msm8998-dpu binding used by the DPU driver. Maybe with the warning telling to update the binding. Then at some point if all the MDP5-supported hardware is supported by the DPU we can drop the MDP5 driver and implement required bindings compatibility in the DPU. > > From where I sit, your position starts with a good idea, but isn't > fully thought out and leads to problems. > > If there is some reason why DPU is better for 8998, please enumerate > it. Does DPU support some config that MDP5 doesn't, which is valuable > to you? The DPU receives more attention from both Qualcomm and Linaro, so it will continue acquiring features (which MDP5 might not have at the moment). For example consider the SmartDMA (multirect) support. For now the multirect patchset it is limited to newer versions, but it might be extended to support older chips (in the DPU) too. We did not have plans to backport SmartDMA v1 support to MDP5. Writeback also has more chances to be supported in the DPU rather than in the MDP5 driver (I remember Rob's patches for the MDP5, but they never actually landed upstream). Last but not least at this moment DPU has bandwidth scaling support, while MDP5 does not. I've sent a patch for MDP5 earlier, which then got reverted because of armv7 support. At this moment I did not resend it since we found some underrun issues on resume or when quickly changing bw down and up. > I'm ok with ripping out the MDP5 support, the reason I didn't > go with DPU was that the DPU driver was clearly written only for 845 > at the time, and needed significant rework to "downgrade" to an > earlier hardware.

While > I disagree with the premise, that "rearch" started with 8998. Just checked, the SDE, the origin (or parent) of the DPU driver starts it's support from the 8996 and 8998.

In any case, removing MSM8998 support from mdp5 is probably a good idea.. dpu1 is "more featureful" already, so it wouldn't really make sense to use mdp5 for a 8998 board right now. I've also validated this on different 8998 devices with both command mode and video mode panels (cmd on Sony Yoshino, video on FxTec Pro1) and they both work fine. >> >> From where I sit, your position starts with a good idea, but isn't >> fully thought out and leads to problems. >> >> If there is some reason why DPU is better for 8998, please enumerate >> it.

Also, sorry for not being immediately ready to reply to my own patch series, my days are a bit messy, currently. Cheers, - Angelo
