02:24 worldhacker: hi all
15:20 Wolf480pl: hi, does anyone have tips on how to reduce run-to-run variance when running vkoverhead? I want to check if my changes to radv introduce a significant overhead, but the variance is making it difficult
15:24 pendingchaos: https://llvm.org/docs/Benchmarking.html has some
15:24 pendingchaos: IIRC "echo 0 > /sys/devices/system/cpu/cpufreq/boost" was the AMD equivalent for the no_turbo thing
15:25 Wolf480pl: thanks
17:37 bl4ckb0ne: intel hd graphics 5500 uses runs anv right?
17:38 bl4ckb0ne: VK_EXT_swapchain_maintenance1 is missing on my system, driver matrix lists it as implemented on anv but no sight of it with vulkaninfo
17:41 glehmann: no, it uses hasvk
17:42 bl4ckb0ne: i though hasvk was only for haswell and lower
17:43 glehmann: it's for everything before skylake (gen9)
17:43 bl4ckb0ne: right, this is broadwell
17:44 bl4ckb0ne: do you know if the ext cant be implemented because of a hw requirement or if nobody bothered yet
17:57 glehmann: probably just nobody bothered
18:47 alyssa: glehmann: broadwell is just spicy haswell iirc
18:48 glehmann: I think later broadwell is closer to skylake than to haswell, that's why iris supports those chips
19:59 bl4ckb0ne: ill see what i can do then, thanks
20:09 bl4ckb0ne: hm seems its also missing a bunch of bindless descriptor features i need
