openpowerbot[irc] <nyanbinary[m]> soooo19:27
openpowerbot[irc] <nyanbinary[m]> uhhh19:27
openpowerbot[irc] <nyanbinary[m]> https://www.tomshardware.com/pc-components/gpus/new-open-source-gpu-is-free-to-all-supports-modern-windows-software-stack-runs-on-an-fpga-with-custom-pcb19:28
openpowerbot[irc] <nyanbinary[m]> this is a thing at least19:28
openpowerbot[irc] <programmerjake> neat! they're not the first fixed-function 3D GPU tho, https://github.com/asicguy/gplgpu19:36
openpowerbot[irc] <nyanbinary[m]> programmerjake: Sure but its cool19:37
openpowerbot[irc] <nyanbinary[m]> how is libresoc going btw19:37
openpowerbot[irc] <nyanbinary[m]> I assume not well19:37
openpowerbot[irc] <nyanbinary[m]> https://www.phoronix.com/news/Libre-GPU-RISC-V-Vulkan imo should of just sticked with RISC-V & levering Rust19:37
openpowerbot[irc] <programmerjake> dmitry and cesar are making some progress, luke and I are not...19:40
openpowerbot[irc] <programmerjake> you can see the weekly sync meeting minutes for more details: https://libre-soc.org/meetings_2024/19:41
openpowerbot[irc] <nyanbinary[m]> o19:50
openpowerbot[irc] <nyanbinary[m]> Is the plan still for a POWER9 CPU?19:50
openpowerbot[irc] <nyanbinary[m]> Also anywhere to read on the architecture of the GPU?19:51
openpowerbot[irc] <programmerjake> no, we were always going to build something different than power9 in particular without vsx/vmx and later with simple-v. the current plan is that we'll likely switch back to risc-v.19:54
openpowerbot[irc] <programmerjake> https://libre-soc.org/3d_gpu/architecture/19:55
openpowerbot[irc] <programmerjake> though that may be out of date19:56
openpowerbot[irc] <nyanbinary[m]> nicee19:56
openpowerbot[irc] <nyanbinary[m]> Love me some RISC-V tbh19:56
openpowerbot[irc] <nyanbinary[m]> Also never heard about simple-v what is it?20:01
openpowerbot[irc] <programmerjake> https://libre-soc.org/openpower/sv/20:01
openpowerbot[irc] <programmerjake> https://libre-soc.org/openpower/sv/overview/20:03
openpowerbot[irc] <nyanbinary[m]> What prompted the switch back to RISC-V?20:03

openpowerbot[irc] <programmerjake> issues with IBM apparently effectively blocking our proposed additions to PowerISA...20:05
openpowerbot[irc] <programmerjake> iirc VCs being more willing to fund RISC-V designs is also an aspect20:06
openpowerbot[irc] <programmerjake> it turns out that IBM blocking is not exactly correct, but by that point we already decided...20:07
openpowerbot[irc] <programmerjake> though they still are going extremely slowly on some parts (which aren't public afaik)20:08
openpowerbot[irc] <nyanbinary[m]> sv was the proposed addition right?20:08
openpowerbot[irc] <programmerjake> yes, but also lots of instructions for other things such as fp load immediate20:09
openpowerbot[irc] <nyanbinary[m]> oo20:15
openpowerbot[irc] <nyanbinary[m]> How about Rust for software side of things20:15
openpowerbot[irc] <nyanbinary[m]> is that still planned?20:15
openpowerbot[irc] <nyanbinary[m]> Is there an updated todo map or anything20:15
openpowerbot[irc] <programmerjake> the vulkan driver has been on hold for a few years while we work on the hardware and on getting it to run linux programs20:36
*** ghostmansd[m] <ghostmansd[m]!~ghostmans@176.59.168.235> has quit IRC20:54
openpowerbot[irc] <nyanbinary[m]> Oo21:03
openpowerbot[irc] <nyanbinary[m]> So any road maps for the RISC-V stuff21:03
openpowerbot[irc] <nyanbinary[m]> and any plan extensions?21:03
openpowerbot[irc] <programmerjake> not really yet...though you can look at the stuff we made before switching away from risc-v https://libre-soc.org/simple_v_extension/21:05
openpowerbot[irc] <nyanbinary[m]> Wonder how close LibreSOC is to a minimal viable product or at least a functional prototype :321:15
