Overview - -Intel's IXP2000 family of NPUs (IXP2400, IXP2800, IXP2850) is designed -for high-performance network applications such high-availability -telecom systems. In addition to an XScale core, it contains up to 8 -"MicroEngines" that run special code, several high-end networking -interfaces (UTOPIA, SPI, etc), a PCI host bridge, one serial port, -flash interface, and some other odds and ends. For more information, see: - -http://developer.intel.com - -2. Linux Support - -Linux currently supports the following features on the IXP2000 NPUs: - -- On-chip serial -- PCI -- Flash (MTD/JFFS2) -- I2C through GPIO -- Timers (watchdog, OS) - -That is about all we can support under Linux ATM b/c the core networking -components of the chip are accessed via Intel's closed source SDK. -Please contact Intel directly on issues with using those. There is -also a mailing list run by some folks at Princeton University that might -be of help: https://lists.cs.princeton.edu/mailman/listinfo/ixp2xxx - -WHATEVER YOU DO, DO NOT POST EMAIL TO THE LINUX-ARM OR LINUX-ARM-KERNEL -MAILING LISTS REGARDING THE INTEL SDK. - -3. Supported Platforms - -- Intel IXDP2400 Reference Platform -- Intel IXDP2800 Reference Platform -- Intel IXDP2401 Reference Platform -- Intel IXDP2801 Reference Platform -- RadiSys ENP-2611 - -4. Usage Notes - -- The IXP2000 platforms usually have rather complex PCI bus topologies - with large memory space requirements. In addition, b/c of the way the - Intel SDK is designed, devices are enumerated in a very specific - way. B/c of this this, we use "pci=firmware" option in the kernel - command line so that we do not re-enumerate the bus. - -- IXDP2x01 systems have variable clock tick rates that we cannot determine - via HW registers. The "ixdp2x01_clk=XXX" cmd line options allow you - to pass the clock rate to the board port. - -5. Thanks - -The IXP2000 work has been funded by Intel Corp. and MontaVista Software, Inc. - -The following people have contributed patches/comments/etc: - -Naeem F.

Peers on the PCI bus running - * Linux is a common design in telecom systems. The problem is that instead - * of all the devices being controlled by a single host, different - * devices are controlled by different NPUs on the same bus, leading to - * multiple hosts on the bus. The exact bus layout looks like: - * - * Bus 0 - * Master NPU <-------------------+-------------------> Slave NPU - * | - * | - * P2P - * | - * - * Bus 1 | - * <--+------+---------+---------+------+--> - * | | | | | - * | | | | | - * ... Dev PMC Media Eth0 Eth1 ... - * - * The master controls all but Eth1, which is controlled by the - * slave. What this means is that the both the master and the slave - * have to scan the bus, but only one of them can enumerate the bus. - * In addition, after the bus is scanned, each kernel must remove - * the device(s) it does not control from the PCI dev list otherwise - * a driver on each NPU will try to manage it and we will have horrible - * conflicts. Oh..and the slave NPU needs to see the master NPU - * for Intel's drivers to work properly. Closed source drivers... - * - * The way we deal with this is fairly simple but ugly: - * - * 1) Let master scan and enumerate the bus completely. - * 2) Master deletes Eth1 from device list. - * 3) Slave scans bus and then deletes all but Eth1 (Eth0 on slave) - * from device list. - * 4) Find HW designers and LART them. - * - * The boards also do not do normal PCI IRQ routing, or any sort of - * sensical swizzling, so we just need to check where on the bus a - * device sits and figure out to which CPLD pin the interrupt is routed. - * See ixdp2[48]00.c files. - * - *************************************************************************/ -void ixdp2x00_slave_pci_postinit(void) -{ - struct pci_dev *dev;
