probably best to wait for the JH7110 variant, assuming they still intend to fix it so DMA is coherent
<Esmil>
i guess that depends on how anxious you are to have some real risc-v hardware, it's cheaper than the sifive boards, but less broken than and more powerfull than the D1s

muurkha: Blender recently has deprecated support for OpenCL, in favour of AMD/Nvidia specific solutions
<dh`>
is there a way to get gas to assemble the new PAUSE by writing it as a FENCE?
<pierce>
Which raises the question, if OpenCL is being dropped, what is the next vendor agnostic solution? Do vendors just need to be convinced OpenCL 3 is the bee's knees?
<dh`>
(I haven't tried, I figure someone here probably knows without having to think about it)
<dh`>
(or experiment)
<jrtc27>
try fence 0, rw or whatever it is
<jrtc27>
that or fence , rw
<jrtc27>
(assuming my memory of the encoding is correct)
<dh`>
I think it's w, 0
<jrtc27>
hm, neither seems to work, at least with the gas on godbolt.org, but its riscv gnu toolchain is pretty old
<dh`>
in the toolchain I have w,0 is rejected and w, assembles to w,w
<dh`>
oh well
<jrtc27>
o.o
<jrtc27>
in what world is w, the same as w,
<jrtc27>
uh w,w
<dh`>
I think the nonideal gas law applies :-)
<jrtc27>
that's a new one to me :')
<jrtc27>
does that mean linux-rt=linux-pv/n
<dh`>
lol

netbsd has far too many fanatic retrocomputing enthusiasts to ever drop 32-bit
plantman has joined #riscv

<jrtc27>
yeah.. and I imagine a subset of those will want a NetBSD/riscv32
<jrtc27>
maybe even rv32e... *shudders*
<dh`>
and I think the current plan is that the riscv port will look like the mips port (both 32-bit and 64-bit mostly from the same assembly sources, via cpp skulduggery)
<dh`>
but I've lost track of what's going on again and haven't had time to attend to it
<la_mettrie>
there won't be 32-bit riscv embedded devices which would need 32-bit OS?
<jrtc27>
I hope your mips port is better than FreeBSD's
<dh`>
you'd think so and you'd think some of the bigger ones would want unix
<jrtc27>
because FreeBSD's port has been a burning pile since the day it was committed
<dh`>
it has had problems but it probably is, it mostly works
<jimwilson>
plt stubs won't work for rv32e, not enough temp regs, so no shared libraries, and there is no a7 for syscall interface so that needs to change too
<jrtc27>
a7 being the syscall number is only a linux thing
<dh`>
I don't know if we're intending to do rv32e
<jrtc27>
(and sbi, because it's just a carbon copy of the linux abi)
<jrtc27>
I'd suggest you don't :)
<dh`>
if you're using rv32e you probably want something lighter than unix
<jrtc27>
yeah, but people like putting netbsd on their toasters
<dh`>
it is true
