Run Unix v4 from your browser

+ +

+Technically, we're booting Linux, to emulate a PDP-11. + +Once Linux is booted run: + +


+cd /opt/unixv4
+pdp11 boot.ini
+
+ +Once you see some info about the controller not being valid, type +
k
it should push you to a newline, then type 
unix
+then hit enter. + +From there you should have a login prompt, at which you can type 
root
+and play with the system as you see fit. +

+
+
+
+
+ + + + +
+

On a Fedora + system you can do it with: + + sudo dnf install openssl-devel libcurl-devel SDL-devel + + It is possible to compile the programs without these libraries by + commenting CONFIG_FS_NET and/or CONFIG_SDL in the Makefile. + +- Edit the Makefile to disable the 128 bit target if you compile on a + 32 bit host (for the 128 bit RISCV target the compiler must support + the __int128 C extension). + +- Use 'make' to compile the binaries. + +- You can optionally install the program to '/usr/local/bin' with: + + make install + +3) Usage +-------- + +3.1 Quick examples +------------------ + +- Use the VM images available from https://bellard.org/jslinux (no + need to download them): + + Terminal: + + ./temu https://bellard.org/jslinux/buildroot-riscv64.cfg + + Graphical (with SDL): + + ./temu https://bellard.org/jslinux/buildroot-x86-xwin.cfg + + ./temu https://bellard.org/jslinux/win2k.cfg + +- Download the example RISC-V Linux image + (diskimage-linux-riscv-yyyy-mm-dd.tar.gz) and use it: + + ./temu root-riscv64.cfg + + ./temu rv128test/rv128test.cfg + +- Access to your local hard disk (/tmp directory) in the guest: + + ./temu root_9p-riscv64.cfg + +then type: +mount -t 9p /dev/root /mnt + +in the guest.

No specific +configuration is necessary. + +TinyEMU also supports a "tap" network driver to redirect the network +traffic from a VirtIO network adapter. + +You can look at the netinit.sh script to create the tap network +interface and to redirect the virtual traffic to Internet thru a +NAT. The exact configuration may depend on the Linux distribution and +local firewall configuration. + +The VM configuration file must include: + +eth0: { driver: "tap", ifname: "tap0" } + +and configure the network in the guest system with: + +ifconfig eth0 192.168.3.2 +route add -net 0.0.0.0 gw 192.168.3.1 eth0 + +3.4 Network filesystem +---------------------- + +TinyEMU supports the VirtIO 9P filesystem to access local or remote +filesystems. For remote filesystems, it does HTTP requests to download +the files. The protocol is compatible with the vfsync utility. In the +"mount" command, "/dev/rootN" must be used as device name where N is +the index of the filesystem. When N=0 it is omitted. + +The build_filelist tool builds the file list from a root directory. A +simple web server is enough to serve the files. + +The '.preload' file gives a list of files to preload when opening a +given file. + +3.5 Network block device +------------------------ + +TinyEMU supports an HTTP block device. The disk image is split into +small files. Use the 'splitimg' utility to generate images. The URL of +the JSON blk.txt file must be provided as disk image filename. + +4) Technical notes +------------------ + +4.1) 128 bit support + +The RISC-V specification does not define all the instruction encodings +for the 128 bit integer and floating point operations. The missing +ones were interpolated from the 32 and 64 ones. + +Unfortunately there is no RISC-V 128 bit toolchain nor OS now +(volunteers for the Linux port ?), so rv128test.bin may be the first +128 bit code for RISC-V ! + +4.2) Floating point emulation + +The floating point emulation is bit exact and supports all the +specified instructions for 32, 64 and 128 bit floating point +numbers. It uses the new SoftFP library. + +4.3) HTIF console + +The standard HTIF console uses registers at variable addresses which +are deduced by loading specific ELF symbols. TinyEMU does not rely on +an ELF loader, so it is much simpler to use registers at fixed +addresses (0x40008000). A small modification was made in the +"riscv-pk" boot loader to support it. The HTIF console is only used to +display boot messages and to power off the virtual system. The OS +should use the VirtIO console. + +4.4) Javascript version + +The Javascript version (JSLinux) can be compiled with Makefile.js and +emscripten. A complete precompiled and preconfigured demo is available +in the jslinux-yyyy-mm-dd.tar.gz archive (read the readme.txt file +inside the archive). + +4.5) x86 emulator + +A small x86 emulator is included. It is not really an emulator because +it uses the Linux KVM API to run the x86 code at near native +performance. The x86 emulator uses the same set of VirtIO devices as +the RISCV emulator and is able to run many operating systems. + +The x86 emulator accepts a Linux kernel image (bzImage). No BIOS image +is necessary. + +The x86 emulator comes from my JS/Linux project (2011) which was one +of the first emulator running Linux fully implemented in +Javascript. It is provided to allow easy access to the x86 images +hosted at https://bellard.org/jslinux . + + +5) License / Credits +-------------------- + +TinyEMU is released under the MIT license.
