The most confused me is how max vlen (128/256/512/1024 ???), we should put it into sigcontext. I need people's suggestions, thx. Anyone help to review the patch are very helpful and we could co-developed together, Thx On Mon, Jan 6, 2020 at 11:00 AM Anup Patel wrote: > > On Mon, Jan 6, 2020 at 8:15 AM Alan Kao wrote: > > > > Hi Guo, > > > > On Sun, Jan 05, 2020 at 10:52:15AM +0800, guoren@kernel.org wrote: > > > From: Guo Ren > > > > > > The implementation follow the RISC-V "V" Vector Extension draft v0.8 with > > > 128bit-vlen and it's based on linux-5.5-rc4. > > > > > > > According to https://lkml.org/lkml/2019/11/22/2169, in which Paul has stated > > that "we plan to only accept patches for new modules or extensions that have > > been frozen or ratified by the RISC-V Foundation." > > > > Is v0.8 ratified enough for now? > > As-per the patch acceptance policy, we cannot merge it now (just like KVM > patches) but we can always review and get the patches in final shape > by the time spec is frozen or ratified. > > I think we should continue with the patch review and get this series in > good shape. > > In fact, having this patches early on LKML is very helpful for people working > on RISC-V vector extension implementation in HW.
