00:01 <alyssa> force caching sources gets me up to 10.1fps ... need to figure out a heuristic for that ...

00:01 <alyssa> 1% improvement? i'll take it lol

10:28 <Mary> nice

11:37 <alyssa> karolherbst: Any chance you would do TIMESTAMP queries?

11:38 <karolherbst> uhm... maybe? are you planning to finish scratch memory + spilling? But I kinda prefer to figure out the linear image situation first, but if timestamp queries are easy enough I can also look into that

11:40 <alyssa> scratch/spilling are nightmare-level difficulty and yes it's in the cards for me & lina

11:41 <karolherbst> lina told me that the uapi is at least done. I can see that spilling is a nightmare to implement, but is scratch on its own as a thread private memory buffer all that complex? lina told me about some of the details though, so I can also kinda see why that's annoying to implement

11:42 <karolherbst> I need scratch for indirect access to temporaries at least

11:43 <karolherbst> but anyway, I can look into TIMESTAMP, I just don't have any of the RE setup done which might be needed here

11:43 <karolherbst> I guess

11:43 <karolherbst> unless it's already REed

11:46 <alyssa> scratch is also nightmare level yes

11:46 <alyssa> timestamp you have two options

11:46 <alyssa> drm_asahi_get_time ioctl

11:46 <alyssa> and drm_asahi_result_* has timestamps in it at the end of the job

11:46 <alyssa> and also os_time_get_nano()

11:46 <alyssa> hf

11:47 <alyssa> it does NOT map to gl timestamps which are bonkers for tilers

11:47 <karolherbst> yeah.. so I kinda need it as part of command submission and as a host query, so probably 1 and 2

11:48 <karolherbst> like I kinda need to know when the GPU reaches a certain point in the command stream

11:50 <karolherbst> anyway.. I need proper support for PIPE_QUERY_TIMESTAMP and pipe_screen::get_timestamp (which I guess should use the drm_asahi_get_time ioctl)

11:50 <karolherbst> I don't need anything inside the shader afaik

11:53 <alyssa> :+1:

11:53 <karolherbst> _but_ I guess `drm_asahi_result_compute` is good enough here, I just have to figure out how to pipe that all through

12:02 <karolherbst> anyway.. what rusticl is kinda doing is to insert `PIPE_QUERY_TIMESTAMP` around gallium API calls, that happens in batches and at some point that all gets flushed out. And reading the result happens all on the CPU side.

14:49 <rosefromthedead> hmm am i needed

14:54 <i509vcb> There's definitely stuff in agxv if you want to burn time there

14:56 <i509vcb> VK_EXT_image_drm_format_modifier is one of the big extensions for getting wlroots vulkan renderer to work, but there are a few dependent extensions needed there

14:56 <rosefromthedead> mb i meant wrt the timer stuff, because i said i'd do that but i haven't got round to it

14:57 <i509vcb> Ah ok nvm

14:57 <rosefromthedead> good to know though :eyes:

15:01 <karolherbst> rosefromthedead: if you want to do that timer stuff feel free, I have way too many other things to work on

15:01 <rosefromthedead> noted
