02:58kode54: try running amdgputop?
04:18superkuh: Unfortunately my version of rustc is too old to run it and the appimage fails because my libc differs.
04:18superkuh: radeontop does show the gross behavior though.
04:19superkuh: Er, to compile it.
04:20superkuh: Oh. amdtop requires amdvlk too.
04:21superkuh: Er, amdgpu_top.
04:22superkuh: Which has dropped support for my card series... but maybe not on the old deb 11 packages.
06:41kode54: Amdgpu top requires a Vulkan driver? But certainly not amdvlk
06:41kode54: Works with radv
08:32MrCooper: superkuh: https://patchwork.freedesktop.org/series/129196/ might help for your issue
08:50superkuh: Wow. Thanks! Compiling and installing my own amdgpu is a bit beyond my skill but I will look into it and give it a try.
11:41haasn: is there a hardware sampling mode that returns the max() of all sampled texels?
11:41haasn: Or would I have to cook such a thing myself e.g. with quad operations
12:17ishitatsuyuki: is that some hi-Z thing
12:19haasn: anti-ringing during video filtering
12:19haasn: I need access to the min and max of the central 2x2 area surrounding the kernel
12:19haasn: and I want to avoid needing to do 4 texture fetches
12:20haasn: but pre-processing would be similarly wasteful, since I only need to run this pass once
12:20pendingchaos: VK_EXT_sampler_filter_minmax?
12:21haasn: oh! I was looking at VkFilter
12:21haasn: that's perfect, thanks
12:21pendingchaos: reminds me that RADV doesn't claim minmax filter support for a bunch of formats it could
12:25haasn: TIL VK_FILTER_CUBIC_EXT exists
12:27ishitatsuyuki: 0% implementation rate actual
12:29haasn: sad
12:30haasn: just qualcomm it seems
