RISC-V support #133

Closed Popolon closed 2 years ago

Popolon commented 2 years ago

When I try to compile on RISC-V (64 bit version) of Debian.

root@debian:~/cpufetch# make
Makefile:45: Unsupported arch detected: riscv64. See https://github.com/Dr-Noob/cpufetch#1-support
Makefile:46: If your architecture is supported but the compilation fails, please open an issue in https://github.com/Dr-Noob/cpufetch/issues
Makefile:47: *** Aborting compilation. Arrêt.

For information on my qemu installation of Debian, I have the following /proc/cpuinfo

processor       : 0
hart            : 1
isa             : rv64imafdcsu
mmu             : sv48

rv32 means RISC-V 32 bits rv64, 64 bits and rv128 128 bits (still in draft). the letter that follow are the names of the extensions:

i=integer
m=mutiply(and divde)
f=float, d=double etc... I have some RISC-V 32 bits and 64 bits MCU, but without MMU. I wait for a RISC-V purpose CPU to test Linux on real hardware RISC-V. Several cheap boards should be available this month.

Dr-Noob commented 2 years ago

Yes, this is expected.

Currently, cpufetch does not run on RISC-V, and I do not have the intention to add support to it shortly (see #101). Maybe next summer, maybe next year... If I can get access to real hardware I will probably change my mind and add support much sooner, so if you can offer anything, I will listen :thinking:.

Closing.

OK, as it was closed I didn't found anything when searching for RISC-V, sorry.

Hi, @Dr-Noob I have the riscv64 machine by hand, please how to help here?

Popolon commented 2 years ago

Sorry, I'm already busy on porting packages and systems since few month on RISC-V, which board do you use. I use mainly Sipeed Lichee-RV for these ports.

yuzibo commented 2 years ago

Thank your work:) Once done, I will forward this to maintainer of cpufetch Debian packages. Background: I am fixing some debian packages on riscv64 that have ftbfs: https://buildd.debian.org/status/package.php?p=cpufetch&suite=sid.

Popolon commented 2 years ago

I pushed a patch for openmsx on Debian lists but don't know if it had worked?

For information, /proc/cpuinfo on LicheeRV (archlinux for RISC-V, linux-5.18rc4 with Smaeul patchs) :

processor   : 0
hart        : 0
isa     : rv64imafdc
mmu     : sv39
uarch       : thead,c906

This is a Allwinner D1 (based on opensource T-Head C906 implementation) RISC-V. There is the 0.7 version specifications of the vector extension (v) on this processor, detected in /proc/cpuinfo on Debian, with kernel 5.14 including several blobby drivers patchs. This cheap SoC use 22nm technology after what I read (need to found again the source).

Great! The link has more riscv cpu info: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1012077
