On Intel, the memory region cache management is available only if the paging unit is enabled. Concerning the buffers and their descriptors, we have tried to optimize the memory space in term of allocated page. Register info for all registered configuration registers. It is possible to override the packet by assigning this attribute. Control and status registers. It means that we will have to re-write some mechanisms of this driver.

This DEC chip uses the host memory to store the incoming Ethernet frames and the descriptor of these frames. Including the required managers 4.

The default value paciet 0 which means that no packages will be lost. Network device configuration 4. First version of this document. The format for each entry is offset, mask. Early versions used National transcievers, but later versions are depopulated ZX boards.

On Intel, the memory region cache management is available only if the paging unit is enabled. We plan to port the DEC driver for the Netboot tool.

This thread is event driven. Write the Driver Statistic-Printing Function 4. Writing this attribute at any time injects a new packet packwt the device without involving the network simulation. How often in seconds that packets are send out to the network. When set to 0, the user has to supply a CRC field with the injected frame.

Network Driver Makefile 3.

We have used this paging mechanism, with 4Kb page. The frame that is currently about to be sent or received. Recorder object that allows recording and later playback of network traffic to the interface.

This chapter describes rapidely the PCI interface of this Ethernet controller. One buffer has bytes, one descriptor has 16 bytes. Register info for all registered configuration registers. By reading or writing these registers, a driver can obtain information about the type of the board, the interrupt it uses, the mapping of the chip specific registers, ….

In this chapter will see the initialization phase, how the controller uses the host memory and the 2 threads launched at the initialization time. Obsolete – see the “last-frame” attribute instead. The format for each entry is offset, name, size, write-mask.


Injecting a packet copies the packet data, allowing the caller to reuse or dispose of the buffer used for creating the packet, after the attribute is written. On Intel target, the chip specific registers can be accessed via 2 methods: The Ethernet link that the network device is connected to.

Netboot DEC driver 7. Driver basic operation 5.

The 64 PCI configuration registers, each 32 bits in size. We have chosen to use 7 receive buffers and 1 transmit buffer to optimize memory allocation due to cache and paging problem that will be explained in the section Packket Problems. Each descriptor can reference one or two memory buffers.

This board includes an Ethernet controller based on a DEC chip. Here is a non exhaustive list of adapters which support this driver: Note that you must always provide room for the CRC paclet, even when this attribute is set to 1.
