Re: Lavapipe performance question during interactive drawing
Hi Dave, Indeed after setting LP_DEBUG=fs I get a lot of repetitive printing during the interactive actions. After some more searching it finally seems that the problem is on our side, which forces some pipelines to be continuously re-created. Thanks everyone for your help, and I apologize for the confusion and the hassle. :/ Best regards, George On Fri, May 5, 2023 at 11:14 PM Dave Airlie wrote: > On Fri, 5 May 2023 at 21:30, George Karpathios wrote: > > > > Hi list, > > > > I'm using Lavapipe for Vulkan software rendering support in a modeling > application.

Thanks once more for your time. That's a lot of fragment shader recompiles in llvmpipe_update_fs, LP_DEBUG=fs might give some more info if you have a debug build of mes. Dave.

Not sure, I may have to get approval first. Will see what I can do. If so, are there any specific options you'd like enabled?

Re: Lavapipe performance question during interactive drawing
Hi Mike, Thanks for responding. I commented the call to lvp_find_inlinable_uniforms() in lvp_pipeline.c but unfortunately it didn't help this time. It may have gotten a bit worse actually.

Hi, Can you try commenting out the same lines from last time and see whether that affects anything?

Lavapipe performance question during interactive drawing
Hi list, I'm using Lavapipe for Vulkan software rendering support in a modeling application. I notice a large performance hit (with any Mesa version) in the following scenario: The user clicks & drags the mouse in order to create a simple shape (e.g. plane, cube, sphere) dynamically and the result is being rendered (basic gray shading) in real-time alongside the movement of the mouse. Lavapipe seems to be struggling a bit to keep up with this action as the frame time goes up to over 1 second. On the other hand, on a more "static" scene I can get great fps (30-60) while panning/rotating a scene, after Mike Blumenkrantz's recent improvements (many thanks for those again!). I've uploaded a screenshot of the VS profiler showing the hot path at https://imgur.com/a/qZBkB51 and I'd appreciate hearing your thoughts on this. Thanks once more for your time. Best regards, George
