01:25 illwieckz: is that spammer a markov chain bot?
05:12 kode54: it's believed they're just somewhat unhinged, and they've been around for like 10+ years
11:20 DottorLeo: @Venemo: hi! i see a lot of work about SDMA and buffer/images copies, just curious it will improve the performances or is it for maintenance/better code reading? :)
11:21 Venemo: DottorLeo: it is a feature that applications can use if they choose to
11:22 Venemo: for certain workloads (but not all), it performs better than alternatives
11:22 Venemo: it's up to the application to decide to use it though
11:23 DottorLeo: Venemo: thanks
11:25 Venemo: current users are some multimedia apps (eg. mpv and ffmpeg), DXVK, and maybe a few Vulkan games though I don't know which
11:26 Venemo: for multimedia apps, the benefit may be eg. lower power consumption
11:27 DottorLeo: DXVK is interesting, should bring a bit more performance on some games?
11:28 Venemo: because we never enabled this feature, there was no opportunity to examine whether it improves perf for DXVK or not
11:29 DottorLeo: well, something shiny new on mesa-git to test :D
11:29 Venemo: it is not merged yet
11:29 DottorLeo: when it will be merged :D
11:29 DottorLeo: i mean
11:29 Venemo: my guess is that it may improve perf for low-bandwidth use cases, for example eGPU users, but other than that I wouldn't expect much
11:30 DottorLeo: APU?
11:30 DottorLeo: i have a 5600G as an HTPC
11:30 Venemo: it will not improve performance for your games at all then
11:31 Venemo: at least I wouldn't expect it to
11:31 DottorLeo: ok :)
11:31 Venemo: but it may lower power consumption for media playback if you use an app that can take advantage of it. I think haasn had some measurements some time ago
11:35 DottorLeo: last thing, but it is more a "curiosity": i've seen that Sparse suppot is only for GFX >8, it is because the hardware supporting it is that generation or because it's buggy on GFX6-7? I've seen some slides on Southern Island arch and they show the Partial Resident Textures feature. Are these two different things or it's only the name that is different?
12:51 haasn: sorry, I still haven't gotten around to benchmarking/testing it properly :D
12:51 haasn: well besides testing that it works without crashing my GPU
15:24 pekkari: is secure display something usable in renoir laptops? I think it may but vendors ships broken bios with no ccp access and psp but I would like to ask around
17:06 agd5f: pekkari: secure display requires special hardware. It's only useful on certain specific platforms.
17:08 agd5f: I doubt you'll see much power savings with SDMA. Since gfx10, it's part of the GFX block so if either GFX or SDMA are used, GFX will be powered up.
17:11 agd5f: it's mostly useful because it's asynchronous so you can do a transfer while some other engine is crunching on something else (e.g., GFX or VCN)
17:11 agd5f: E.g., A+A laptops where you render on the dGPU and then transfer the frame to the APU for display
