What's in this patch?

This patch contains an update to the enumerator for graphics devices, in order to support the Dell PowerEdge 840. (Ref# 41462)

Installed files

The following file is installed under $QNX_TARGET and under /:

Fixed issues

The officially supported Dell PowerEdge 840 system consists of the following components and options, based on current configuration options available at:

http://www.dell.com/content/products/features.aspx/pedge_840?c=us&cs=04&l=en&s=bsd

• Processor: Dual-Core Intel PentiumD
• Chipset: Intel 3000 (consists of Intel E7230 Memory Controller Hub, with Intel 82801G (ICH7) I/O Controller)
• Graphics: on-board ATI ES1000 (PCI Vendor ID 0x1002, PCI Device ID 0x515E)
• Memory: 1 Gigabyte DDR2
• Network Adapter: on-board single Gigabit Network Adapter -- currently a Broadcom NetXtreme BCM5721 Gigabit Ethernet PCI express (PCI Vendor ID 0x14E4, PCI Device ID 0x1659)
• Primary Hard Drive Controller: on-board SATA, no RAID
• Hard-drive configuration: on-board SATA, 1 drive connected to on-board SATA controller (no RAID)
• Primary Hard Drive: 80 GB SATA 3.5-inch, 7.2 KB RPM hard drive
• No second, third, or fourth hard drive, no additional HD controller, no keyboard / mouse (tested with Dell USB keyboard, and Microsoft optical USB wheel mouse)

QNX Momentics 6.3.0 SP3 currently supports all of the devices and peripherals listed above, and devg-radeon.so supports the ATI ES1000 graphics controller. However, the PCI Device ID for the ES1000 isn't present in the current graphics enumerator list. To add support for this device, you can simply replace the existing file with the updated file included in this patch, or else you can manually modify the file, as shown below.

By default, the VESA graphics driver is used. Log in as root, and change directories to /etc/system/enum/devices/. Edit the graphics file and look for these lines:

device(pci, ven=$(PCI_VEND_ATI), dev=3e50)              # ATI Radeon X600
    cfgfile(fname, /etc/system/config/graphics-traplist)
    echo(devgt-iographics -dldevg-radeon.so -I$(index) "-d0x$(ven),0x$(dev)", $(fname))
    echo(devgt-iographics -dldevg-vesabios.so -I$(index) "-d0x$(ven),0x$(dev)", $(fname))
    echo(devgt-iographics -dldevg-svga.so -I$(index) "-d0x$(ven),0x$(dev)", $(fname))

Change them to look like this:

device(pci, ven=$(PCI_VEND_ATI), dev=3e50)              # ATI Radeon X600
device(pci, ven=$(PCI_VEND_ATI), dev=515e)              # ATI ES1000
    cfgfile(fname, /etc/system/config/graphics-traplist)
    echo(devgt-iographics -dldevg-radeon.so -I$(index) "-d0x$(ven),0x$(dev)", $(fname))
    echo(devgt-iographics -dldevg-vesabios.so -I$(index) "-d0x$(ven),0x$(dev)", $(fname))
    echo(devgt-iographics -dldevg-svga.so -I$(index) "-d0x$(ven),0x$(dev)", $(fname))

Save your changes and exit the editor.

Once you've modified or replaced the file, reboot the system.

The next time the system boots into Photon, Photon will indicate that a new graphics device has been detected, and will display the window allowing you to set and test the resolution and colour depth for the Radeon graphics device. Set this according to your desired preference, and click Apply. Once the system has switched to the new mode, select Accept, and then Done.
