8 | 1. Overview | ||
9 | |||
10 | Intel's IXP2000 family of NPUs (IXP2400, IXP2800, IXP2850) is designed | ||
11 | for high-performance network applications such high-availability | ||
12 | telecom systems. In addition to an XScale core, it contains up to 8 | ||
13 | "MicroEngines" that run special code, several high-end networking | ||
14 | interfaces (UTOPIA, SPI, etc), a PCI host bridge, one serial port, | ||
15 | flash interface, and some other odds and ends. For more information, see: | ||
16 | |||
17 | http://developer.intel.com | ||
18 | |||
19 | 2. Linux Support | ||
20 | |||
21 | Linux currently supports the following features on the IXP2000 NPUs: | ||
22 | |||
23 | - On-chip serial | ||
24 | - PCI | ||
25 | - Flash (MTD/JFFS2) | ||
26 | - I2C through GPIO | ||
27 | - Timers (watchdog, OS) | ||
28 | |||
29 | That is about all we can support under Linux ATM b/c the core networking | ||
30 | components of the chip are accessed via Intel's closed source SDK. | ||
31 | Please contact Intel directly on issues with using those. There is | ||
32 | also a mailing list run by some folks at Princeton University that might | ||
33 | be of help: https://lists.cs.princeton.edu/mailman/listinfo/ixp2xxx | ||
34 | |||
35 | WHATEVER YOU DO, DO NOT POST EMAIL TO THE LINUX-ARM OR LINUX-ARM-KERNEL | ||
36 | MAILING LISTS REGARDING THE INTEL SDK. | ||
37 | |||
38 | 3. Supported Platforms | ||
39 | |||
40 | - Intel IXDP2400 Reference Platform | ||
41 | - Intel IXDP2800 Reference Platform | ||
42 | - Intel IXDP2401 Reference Platform | ||
43 | - Intel IXDP2801 Reference Platform | ||
44 | - RadiSys ENP-2611 | ||
45 | |||
46 | 4. Usage Notes | ||
47 | |||
48 | - The IXP2000 platforms usually have rather complex PCI bus topologies | ||
49 | with large memory space requirements. In addition, b/c of the way the | ||
50 | Intel SDK is designed, devices are enumerated in a very specific | ||
51 | way. B/c of this this, we use "pci=firmware" option in the kernel | ||
52 | command line so that we do not re-enumerate the bus. | ||
53 | |||
54 | - IXDP2x01 systems have variable clock tick rates that we cannot determine | ||
55 | via HW registers. The "ixdp2x01_clk=XXX" cmd line options allow you | ||
56 | to pass the clock rate to the board port. | ||
57 | |||
58 | 5. Thanks | ||
