09:02 DavidHeidelberg: jasuarez: alyssa just don't forget that booting machine and uploading data cost something
09:03 DavidHeidelberg: so, please, 15 min is good. Cost of paying 2 minutes for upload/boot is much more on 10m job than on 13-15m
09:06 jasuarez: Right. When I say 15min is for the girls job, which includes downloading stuff, booting, testing, uploading and finishing
09:06 jasuarez: s/girls/gitlab
09:07 jasuarez: I find particularly more clear to limit jobs to 15 min rather than specific testing to 10min
22:26 nep_nep: Hello, based on https://www.collabora.com/news-and-blog/news-and-events/nvk-is-now-ready-for-prime-time.html I am aware that NVK + zink can give better performance than the native opengl driver in some cases, but surely that is due to a difference in the quality of each driver (due to NVK being written now that nvidia driver development is better understood), rather than inherent to zink. I imagine if an opengl driver and a vulkan driver were
22:26 nep_nep: equally well written, then using the vulkan one with opengl translation would have some level of overheaad (even if small), so I'm wondering, is the "minimum theoretical overhead" of opengl -> vulkan translation (with the opengl and vulkan drivers being equally good on their own) known? Is it significant enough to potentially warrant a from-scratch opengl driver in the far future?
22:29 Company: people have discussed that question a few times in here
22:29 Company: and the answer is "it depends"
22:31 Company: it depends on what your bottleneck is, it depends on the work you're trying to do on the GPU, it depends on the manpower you have to invest in bringing up a full driver, it depends on how fast Vulkan will replace OpenGL, and it depends on a bunch of other things I don't remember
22:37 nep_nep: understandable
22:42 Company: I think it also depends on how much time is invested into making zink fast - because zink doesn't always take the most common Vulkan codepaths
22:43 Company: "making zink fast" meaning both zink itself, but more importantly making sure the Vulkan driver optimizes for zink
22:44 Company: if you have a well-working GL driver, that's less useful, but if zink is your GL driver, it's way more interesting
22:56 nep_nep: At this point I'm just glad nvk exists honestly, even if opengl isn't as optimized as it could be. When I started using linux (early 2021) an open source nvidia vulkan driver seemed like a pipe dream, and at that point the nouveau kernel module didn't have GSP support yet so even opengl was far from great.
