@0x4a6f:matrix.org[0x4A6F] New Milk-V Titan announced. 19:38:58
@zimward:zimward.moezimward Compliant with RVA23* (Excluding "V" Extension) lol, so just with hypervisor support 19:49:17
@0x4a6f:matrix.org[0x4A6F] But without full RVA23 features. 19:49:21
@0x4a6f:matrix.org[0x4A6F]Why can't hardware vendors ...19:49:54
@dramforever:matrix.orgdramforevergluten free (except bread)19:50:49
@0x4a6f:matrix.org[0x4A6F]Waiting for something with some juice P870-D in it...19:52:14
@alex:tunstall.xyzAlexIs the RISC-V foundation not policing vendors' use of marketable words?19:53:18

@rosscomputerguy:matrix.orgTristan Ross Just saw this floating around, more specifically the SoC it uses. Would be cool to run NixOS on it. https://milkv.io/titan 16:40:13

In reply to @zimward:zimward.moe
Tristan Ross how is your tenstorrent card performing so far?
I haven't ran anything on it yet

@dramforever:matrix.orgdramforever just throwing this out there, has anyone tried ubootVisionFive2 without the opensbi override? 11:56:31
@dramforever:matrix.orgdramforeveri have a feeling that the u-boot docs at https://docs.u-boot.org/en/latest/board/starfive/visionfive2.html#building have been written while assuming a non-PIE-capable toolchain11:59:38
@dramforever:matrix.orgdramforeversupport for non-PIE boot was outright removed in opensbi since11:59:53
