[9fans] Plan 9 C compiler for Xtensa CPUs

I was reading the post Why Didn't Plan 9 Succeed on Hacker News. Made me think that Plan 9 for IoT system of systems could be viable. To that end, ESP-32 modules look capable enough to run Plan 9, but is there a Plan 9 C compiler for Xtensa ISA CPUs

Re: [9fans] Plan 9 security

I don't think OpenBSD will run on an ESP-32. That is part of the problem with IoT, the nodes are made on the cheap and thus use the cheapest viable network capable device. On Tue, 20 Aug 2019 at 00:54, Ethan Gardener wrote: > On Mon, Aug 19, 2019, at 12:53 PM, Cyber Fonic wrote: > &

Re: [9fans] Plan9 on virtual machine in Mac os

I have been using Russ Cox's 9vx on OS/X Mavericks with considerable success. The only issue being that I need to connect a Logitech 3 button mouse via a Unifying RF dongle (BlueTooth mice don't work for me). Although 9vx is somewhat minimal, I download sources as I requi

As for strings to pull, try: String 1 String 2 Hope that helps ! It's where I launched my research from. On Wed, 25 Mar 2020 at 12:33, Mark Everett wrote: > Mostly a lurker so far, but wanted to try the actual system rat

Re: [9fans] Alternative to fine-grained mouse usage?

I used to have serious CTS issues from using a mouse. Clenching a mouse and fine motor movement became physiologically incompatible actions for me. My simple low cost solution is to have a USB connected Logitech trackball under my right hand (I'm right handed) and a common wheel USB mouse with th

Re: [9fans] tinyemu - riscv emulator

I had difficulty in getting tinyEmu from contrib/miller/tinyemu.tar working. So I downloaded from Fabrice Bellard's web site and finally got it running the Linux that is referenced on his web site. I also have Richard Miller's RISC-V compiler compiled under x386 Plan9. BUT ... I can't find anythin

Re: [9fans] tinyemu - riscv emulator

The make command failed with dependency on slirp module. The download from Fabrice's website included slirp and the make ran to completion. My *real unsolved issue* is that I don't understand how to create a version of Plan9 that boots and runs on tinyemu. I confirmed that tinyemu itself runs fin

Re: [9fans] tinyemu - riscv emulator

Thank you for the nudges towards the right direction. Self-inflicted confusion : I'm running 9vx and forgot that I was mk'ing an emulator to run within an emulator. After a lot of fiddling with libraries, dependencies I got tinyemu to compile and run. When I execute: tinyemu bridge.cfg It can't

Re: [9fans] tinyemu - riscv emulator

Thanks for the lead. Checked Geoff Collyer's web site and the release of the Plan9 kernels for RISC-V are imminent. I'll wait for Geoff to release the new kernels. In the meantime I have some low-level programming work with your compiler and tinyemu running o

Re: [9fans] NIX experience

Whilst there are many HPC workloads that are well supported by GPGPUs, we also have multi-core systems such as Ampere One and AMD EPYC with 192 cores (and soon even more). I would think that some of the Blue Gene and NIX work might be relevant on such hardware. On Sat, 28 Dec 2024 at 15:18, Anthon

[9fans] Plan9 C compiler targetting WASM

My Google-fu is not coming up with any definitive results. Does anybody know of any implementation of Plan9 C compiler targeting WASM ? On a related note: I believe there was some work being done to target RISC-V. I can't remember who or where it was located. Appreciate any references or comment

Re: [9fans] Plan9 C compiler targetting WASM

I admire the cross-compilation capabilities of Plan9. Compared to gcc and Clang, Plan9 C compilers appeal to my sense of aesthetics. There are some utilities that I would like to port to browser environments and I am loath to use plan9port sources and thus wrangle with gcc, etc. I totally concur w
