Creaky Old Fedora Core Linux for SGI L3/L2

Running SGI L2/L3 Emulator on Fedora Core (yarrow) with QEMU/KVM Virtual Machine

Creaky Old Fedora Core Linux for SGI L3/L2

Status: 30th August 2020 - still testing.

Sometimes you want to do something and sometimes you need to do something. Playing with very old Fedora Core was not a want, it was a need to be able to get some other old creaky software running that needs a Linux 2.4 Kernel.

Getting a very old Fedora Core (yarrow) Release 1 running has it quirks, especially if you are also trying to do this by creating QEMU / KVM virtual machines.

The Problem

I have an old SGI Onyx 350 (O350) machine. This consist of a number of chassis linked together via a Numalink router all controlled via a device known as an L2 Controller and each individual machine has an L1 controller which are connected to the L2 Controller via USB. These in turn can be managed via an L3 Controller (or just Telnet to the L2) which is provided as a software solution running on RedHat Linux.

The Linux based L3 software also includes an L2 emulation capability and needs a 32 bit Linux 2.4 kernel. So running this requires a Linux from around 2002 - 2004.

Additional needs include: Korn Shell & USB support.

Finally on top of the physical machine software needs I have tried to move the L2 Controller onto a QEMU / KVM VM on top of Ubuntu 20.04. This bring need to have support for EvTouch USB Tablet driver as well. EvTouch was originally introduced around 2002 (based on code copyright notice).

The USB driver and other device input code within Linux was under rapid development at this time, so there are many dependencies that can stop this stack from working,

The Options

As the SGI software was officially released for RedHat Linux the obvious answer is to use this. The original RedHat version would likely be RedHat Linux Release 8/9. However RedHat has pretty much deprecated its original RedHat Linux releases for RHEL and RedHat 9 series merged into Fedora Core project.

My Linux distribution preference is Ubuntu but the first Ubuntu release was already Linux kernel 2.6. So Fedora  was the selected option, as it closest to RedHat and Fedora Core R1 is built on top of 2.4 kernel.

My initial choice was to build the L3 Controller on top of VMWare, but this was abandoned when it proved impossible to get USB working, so I dug out an old PC of simillar vintage. Getting physical machine running on Fedota  Core R1, was a straight forward installation. The steps are basically same as documented here, but without X11 Pointer Device issues.

So next option is to see if it is possible to get this running QEMU / KVM on Ubuntu 20.04 which adds the need to try to get EvTouch USB input or some other Tablet option running.

The Hick-ups

Along the way I had to deal with the following hickups.

SSH/SFTP and Encrpytion Negotiation

A common problem with old devices and systems is that ssh/sftp connections request fail with encryption exchange failure due to deprecating support of older and less secure protocols. So you can resort to using telnet which has no encryption at all or try to see if you can get your existing client to connect with one of the less secure protocols.

Here is typical sequence:

# ssh YOUR-ID@HOST.DOMAIN
Unable to negotiate with 192.168.XXX.XXX port 22: no matching key exchange method found. Their offer: diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1

--- Try again with proposed key exchange method...

# ssh -oKexAlgorithms=+diffie-hellman-group1-sha1  YOUR-ID@HOST.DOMAIN
Unable to negotiate with 192.168.XXX.XXX port 22: no matching cipher found. Their offer: aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour,aes192-cbc,aes256-cbc,rijndael-cbc@lysator.liu.se

--- Now add the encryption ciper...

# ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -c aes192-cbc YOUR-ID@HOST.DOMAIN
YOUR-ID@HOST.DOMAIN's password:

--- ok now good to go

Finding a yum repository...

When dealing with "Vintage" releases like Fedora Core R1 (yarrow) you will find that the original yum/apt repositories are no longer available. For historical Fedora core I found the following repositories.

Base:

Updates:

So configure /etc/yum.conf approrpriately (I used the mirror as using processor cycles to encrypt this repository, is a waste of CPU cycles and electricity ;-) ).

# cat /etc/yum.conf
[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log

Installing Korn Shell (ksh)

Korn shell is required for the SGI utilitities, but it is not installed by default. If you did not have access to repository , then you might think, "ok its just a another shell (not a born again one ;-) )". I started down this course but quickly ended up deep in the rough trying to get ksh compiled via AST source repository. The easy way is to take the penalty and go back by updating your yum repository, then its a simple yum command to get pdksh installed (I suspect that the pd == public domain):

# yum install pdksh

I will do the following:

Avoiding RPM Key Check Errors...

RPM package have embedded digitial signatures and these are checked against known ones before will let you install a package, the typical error you will see is:

# rpm -i <LOCATION>/XFree86-4.3.0-55.src.rpm                   
warning: /var/tmp/rpm-xfer.rMNqgB: V3 DSA signature: NOKEY, key ID 4f2a6fd2

The work around is way simpler than most of the online "tips" advise...

# rpm -ivh --nosignature YOUR-FAVOURITE.rpm

Getting source code via RPM packages

To do USB & X11 build requires you to install the sources code RPM. These must match the version of the repository versions. To get the source you ned to invoke rpm directly now via yum:

#
---
--- Using the same repository you set up for yum,
---    look for src packages and then install these directly via rpm
---

# rpm -ivh --nosignature http://mirrors.kernel.org/fedora-buffet/archive/fedora/linux/core/updates/1/i386/SRPMS/kernel-2.4.22-1.2199.nptl.src.rpm
Retrieving http://mirrors.kernel.org/fedora-buffet/archive/fedora/linux/core/updates/1/i386/SRPMS/kernel-2.4.22-1.2199.nptl.src.rpm
   1:kernel                 ########################################### [100%]

The source code will be in either the /usr/src directory or redhat directory below this. The sources in redhat directory are in tar archives.

NOTE: Installing the src package does not result in new package install record being created.

No EvTouch USB Tablet with very old Linux

The SGI applications are X11 GUI based and need a working X11 Pointer Input Device. The only device that works correctly via VNC with QEMU / KVM /libvirt is the EvTouch USB Tablet. This provides absolute (rather than relative position) to its driver to work correctly with VNC. The other option is to capture a physical USB mouse, but this then means you cannot use the mouse with any other window as its capture means you cannot get any input to any outside windows.

The EvTouch driver was developed in around 2002 and this was the same time frame that Linux kernel 2.4 -> 2.6 was in transition to adopt "Linux Input Drivers". This code is not part of Fedora Core R1.

The EvTouch code (0.6) uses the evdev (/dev/input/eventX) interface, which is part of the "Linux Input Drivers". This is all early code in Linux 2.4 and requires compiling from source to get running.

I was able to compile EvTouch, but the EvTouch tablet get detected as an "HID" (Human Interface Device) which it is and connected to the hid driver. However the hid driver does not recognise it. Even though evdev is part of installed kernal, there is no configurable way to control which device gets directed to which driver (hid, evdev, evtouch, wacom etc).  Looking at this I found the Wacom Tablet installation instructions and code. In the wacom code you can see where it has added support for Wacom devices by updating the "hid-core.c" code to stop it passing control to "hid" driver. Here is the HID_QUIRK_IGNORE example code from the Wacom driver.

struct hid_blacklist {
	__u16 idVendor;
	__u16 idProduct;
	unsigned quirks;
} hid_blacklist[] = {
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_PENPARTNER, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_GRAPHIRE, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_GRAPHIRE + 1, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_GRAPHIRE + 2, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_INTUOS, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_INTUOS + 1, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_INTUOS + 2, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_INTUOS + 3, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_INTUOS + 4, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_PL, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_PL + 1, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_PL + 2, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_PL + 3, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_PL + 4, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_PL + 5, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_INTUOS2, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_INTUOS2 + 1, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_INTUOS2 + 2, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_INTUOS2 + 3, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_INTUOS2 + 4, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_INTUOS2 + 5, HID_QUIRK_IGNORE },
	/* Intuos2 6x8 reports as 0x47 instead of 0x42 */
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_INTUOS2 + 7, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_VOLITO, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_GRAPHIRE + 3, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_GRAPHIRE + 4, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_WACOM, USB_DEVICE_ID_WACOM_PTU, HID_QUIRK_IGNORE },
	{ USB_VENDOR_ID_KBGEAR, USB_DEVICE_ID_KBGEAR_JAMSTUDIO, HID_QUIRK_IGNORE },

So I to get evtouch driver working with Fedora Core R1, would require at least:

  • /lib/modules/2.4.<VER>/kernel/drivers/usb/hid.o - KLM to be updated to add quirks to stop passing control to hid and
  • /lib/modules/2.4.<VER>/kernel/drivers/usb/evtouch.o - KLM to be compiled against Fedore Core R1 kernel & XFree86 versions.
  • /usr/X11R6/lib/modules/input/evtouch_drv.o - X11 input driver to be compile against Fedora Core R1 kernal and XFree86 versions.

I did test with hacked hid.o & evtouch.o but could not get any event output on /dev/input/eventX for the driver.

While doing this I noticed that while there is no EvTouch driver with Fedore Core R1, there is a USB Wacom Tablet driver and a review of QEMU documentation indicates that there is an "usb-wacom-tablet" option available, it is just not selectable via Virtual Machine Manager (virt-manager) UI. So I thought I would see if I could get the Wacom driver to work with QEMU / KVM.

QEMU Wacom Tablet alternate to EvTouch

VMM (virt-manager) libvirt UI only provides input options:

  • PS/2 Mouse & Keyboard and
  • USB Mouse, EvTouch Tablet and USB Keyboard.

There is a way to add usb-wacom-tablet into libvirt XML by using the "commandline" option. Here is sample libvirt XML snippet with Wacom USB Tablet configuration added:

After some considerable tweeking of the QEMU / KVM machine and X11 input configuration this is now working (through mouse tracking is a little erratic). I set up two machines with the same configuration, one tracks the mouse perfectly and one has pointer displaced.

Here is "/etc/X11/XFreeConfig" configuration for Wacom X11 driver.

Clonezilla'ing disk & fixing grub

I first got this going using an old IBM PC and the old Fedora Linux release.  I had attempted without succes to get a virualised environment going with VMWare (as I had never tried QEMU / KVM at that time). As I did the physical setup a few years ago I did not remember the exact steps required to get his working. As I already had working physical configuration, I virtualized this as well creating new VM from scratch to help with testing various QEMU / KVM configuration options.

This involved trying/using the following:

  • Clonezilla - image of physical disk and restore to virtual disk
  • gpartd - resizing and copying of partitions from one disk to another
  • fixing of Master Boot Record (MBR) (dd, sfdisk)
  • reinstalling GRUB via  Yarrow CD-ROM Linux Rescue

Info to follow...

SGI L1 USB Cycling on Host Machine

Final hurdle is that when SGI L1 is connected the host Ubuntu 20.04 USB driver is going through connect / disconnect cycle, which means it is not possible to get stable USB connection that can be re-directed to the VM:

$ dmesg | grep usb
[ 1777.251564] usb 3-3: USB disconnect, device number 95

Suspect this is due to host not being aware of how to handle the device, so need to look at how can create a USB Quirk definition for the host OS.

The Result

Here is current QEMU / KVM machine details that work with Fedora Core R1 and allow installation of the SGI software:

  • QEMU - i440FX Ver 3.1 with 2 x Cores CPU Model "coreduo"
  • e1000 - Intel NIC
  • USB 2.0 - this is very important if you do not change USB from the default 3.0 to 2.0 the VM will fail on CDROM install, at the "anaconda" HW detection stage, consistently (but sometimes it might boot and install successfully)
  • Generic PS/2 Mouse & Keyboard
  • Wacom USB Tabet (configured as above)
  • IDE CDROM & HD
  • QXL Video Driver
  • USB Redirector - to allow redirection of host connected USB device to the VM

I have now got this to running VM, the final step is to connect this to SGI O350 L1 port and verify that USB interface is working.

Steps for installation:

  1. Create new VM as above and boot into install CD
  2. During install select: Standard 3 Button PS/2 Mouse, default Monitor, Development Software (including Kernel, X11 & Gnome)
  3. Optionally configure static IP address
  4. Reboot
  5. Configure Wacom USB Tablet (as above)
  6. Configure yum repositories
  7. Reboot
  8. Do "yum install pdksh"
  9. [Optionally: for Fedora Core 6 - also install tck/tk - "yum install tk"]
  10. Do "yum update" to update to: 2.4.24-1.2199.nptl (nptl == native posix thread library)
  11. Do rpm kernel & XFree86 source install using rpm from same respository you configured for yum.
  12. Download and install the SGI L3 & L2 emulation software (see below).
  13. Reboot and you should get below.

Here is screen shot with L2 emulator & UI running via QEMU / KVM machine. The SGI software is installed in: /stand/sysco

SGI Linux - L2 GUI & Emulator on QEMU/KVM Virtual Machine

Now just need to turn on o350 and validate that USB can be connected to VM (see note above about cycling USB..)

NOTE 1: I have also been testing with Fedora Core R6 (with 2.6 Kernel), but L2 crashes with segmentation fault, so this will not work.

Links & References:

EvTouch - is required to use KVM machine via VNC, here is historial page on very early EvTouch releases

Fedora Archive - Fedora Core was an offshoot of initial RedHat distirbution and went through 7 release before becoming plain "Fedora"

A YUM accessible Fedora Core Repository - having access to a bunk of RPMs is not as useful as having full set of repositories, I found this mirror which as all Fedora release. Here is yarrow i386 repository.

Linux Input Drivers - Version 1.0 documentation by Vojtech Pavlik (who is/was part of SUSE team) from back in 1999-2001. These provide an intesting case study of use of abstraction to manage a very large and diverse set of underlying input and usb devices. The starting "point" for this was with JoyStick drivers for Linux Games Console support (see Linuxconsole below).

Linux USB Project - as QEMU / KVM EvTouch USB Tablet devices is USB, the support this this requires Linux USB drivers.. here is the historical beginning of the modular USB Driver Project.

Linuxconsole Project - following the detective trial on how to test evdev led to the Linuxconsole project which us where the evtest program was sourced from. I went back to the oldest version I could find 1.24 from 2009 and needing to updated to remove a set of key definitions that are not defined in old 2.4 kernel header file.

Linux Wacom Tablet Drivers - these include early hacks (I used the 0.6 driver which supports kernel 2.4.22) to work with still under development Linux Input Drivers and required replacement: input, mouse and hid drivers to work. The number of site for this is confusing... there is SourceForge, Ubuntu Community Help & github pages/sites. I just wound back based on getting Linux kernel 2.4 going.

SGI - L3 & L2 Emulation software was distributed on IST CDROM, here is version 3.24 .

sgil1 USB Driver - I have uploaded the code to github and hacked this to try to get it working on Ubuntu 20.04

evtest hack - The hacked evtest code to get this working with old Fedora Core R1 (yarrow) is up on githib (see the retro branch)

Working Technical Notes...

What USB devices does kernel see when I have QEMU EvTouch USB Tablet & Mouse attached connected to VM ?

What does this mean ...

It has recognised both Tablet and Mouse and allocated inputs to the hid (Human Interface Driver):

  • Vendor == S: QEMU with id=0627
  • Driver == I: hid (Human Interface Device) in both cases
  • Device Class = I: HID - Cls=03 (HID )

Doing lsmod to see if evdev driver is loaded shows that it is not loaded.

---
--- Check that evdev is loaded
---
# lsmod | grep evdev

---
--- Load the evdev KLM (modprobe)
---

# modprobe evdev

---
--- Check that it loaded ok (lsmod)
---

smod | grep evdev      
evdev                   5184   0 
input                   5888   0  [evdev keybdev mousedev hid]

Are we getting any event data, using evtest (from LinuxConsole project):

evtest /dev/input/event0
Input driver version is 1.0.0
Input device ID: bus 0x3 vendor 0x627 product 0x1 version 0x0
Input device name: "QEMU QEMU USB Tablet"
Supported events:
  Event type 1 (Key)
    Event code 272 (LeftBtn)
    Event code 273 (RightBtn)
    Event code 274 (MiddleBtn)
  Event type 2 (Relative)
    Event code 8 (Wheel)
  Event type 3 (Absolute)
    Event code 0 (X)
      Value      0
      Min        0
      Max    32767
    Event code 1 (Y)
      Value      0
      Min        0
      Max    32767
Testing ... (interrupt to exit)

Starts well but pressing mouse buttons and moving mouse does not show any data. So looking at USB devices show that the device is still using "hid" driver not the "evdev" driver, so that is why not events are present.

Need to look at the WACOM code to see how they got around this...

Build and Load sgil1 USB Driver on Ubuntu 20.04 machine

To stop the cycling of L1 when connected to VM host, I thought maybe if a built the sgil1 USB driver for Ubuntu host then that would capture the L1 and stop the cycling.

Here is sgil1 USB loaded on Ubuntu 20.04 machine:
