-Release Notes for Linux on Intel's IXP2000 Network Processor
-
-Maintained by Deepak Saxena <dsaxena@plexity.net>
--------------------------------------------------------------------------
-
-1. 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.
-

- * IXDP2x00-common PCI init
- *
- * The IXDP2[48]00 has a horrid PCI bus layout. Basically the board
- * contains two NPUs (ingress and egress) connected over PCI, both running
- * instances of the kernel. So far so good. 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.
