Re: [Vm-dev] [Cuis-dev] Cuis on a RISC

No. MIPS, ARM, and RISCV are all RISC architectures, and there is a RiscOS which runs on ARM. https://www.riscosopen.org/content/ Right now the image is running well, but I get an error PNGReaderWriter crc error in chunk IHDR But this does come up in the debugger! Not by crashing. Probably an edge case with passing structs. Callouts and FFI need more testing. But, hey, celebrate success! Ran the first time I got everything to compile. Wow! Bless the OpenSmalltalk crew! :) Note that Allwinner D1 is a slow chip. One core. LicheeRV is finiky. No graphics acceleration. Early days Debian Linux. You have to be comfortable with Linux and SD cards to attempt it. I wrote up basics at https://github.com/KenDickey/opensmalltalk-vm-rv64/blob/Cog/building/linux6… You probably want to read that first. But, we are supposed to get fast, relatively cheap risc boards later this year. Perhaps BeagleV? We have to be ready! ;^) Good on ya, -KenD

[OpenSmalltalk/opensmalltalk-vm] Boot parameter -headless ignored in Windows 10 (Issue #639)
by Dr. Nicola Mingotti 14 Jun '22

14 Jun '22

Hi, I am trying to deploy CuisSmalltalk as a scripting language in Windows 10. I am running the latest release of the VM `Win32 built on Jun 2 2022 15:29:46 Compiler: Clang 14.0.3 [Production Spur 64-bit X64 VM]`. I got almost all working but I found this little roadblock. As far as I can say the "-headless" parameter is ignored in Windows 10. ---- demo, headless is ignored. ``` win cmd> C:\CUIS\squeak.cog.spur_win64x64\SqueakConsole.exe -headless C:\CUIS\Cuis6.0-5031.image -d "StdIOWriteStream stdout nextPutAll: 'hello world'; newline." -d "Smalltalk quit." => hello world [ headless is not working, if you remove the 'Smalltalk quit' you will see the window is well alive]. ``` By comparison the parameter "-vm-display-null" works very well in Linux. ---- demo, fully working, windows ghost popping up as in Linux. ``` $> ./sqcogspur64linuxht/squeak -vm-display-null Cuis-Smalltalk-Dev/Cuis6.0-5031.image -d "StdIOWriteStream stdout nextPutAll: 'Hello World'; newLine" -d 'Smalltalk quit.' => Hello World [and goodbye] ``` bye Nicola -- Reply to this email directly or view it on GitHub: https://github.com/OpenSmalltalk/opensmalltalk-vm/issues/639 You are receiving this because you are subscribed to this thread.

Taking a RISC
by ken.dickey＠whidbey.com 14 Jun '22

Greetings, More work to do, but I got a $25 RISC development board (Sipeed Lichee RV Dock) and got opensmalltalk-vm working with Cuis (Note truetype fonts and vector graphics rotation). Older vm version to update and debug to do, but basic image/windows/tools work fine on real RISC-V RV64G hardware! https://github.com/KenDickey/opensmalltalk-vm-rv64 FYI, -KenD

This is unlikely, but can happen with large image segments if memory is scarce. Fix received from Max Leske with thanks. A little less inlining does you good. Don't inline allocateSlots:format:classIndex: in low-frequency primitives. Improve some comments in the changed methods.
