DESCRIPTION

     The atse device driver provides support for the Altera Triple-Speed Ethernet MegaCore.

HARDWARE

     The current version of the atse driver supports the Ethernet MegaCore as described in version 11.1 of Altera's documentation when the device
     is configured with internal FIFOs.

MAC SELECTION

     The default MAC address for each atse interface is derived from a value stored in cfi(4) flash.  The value is managed by the atsectl(8) util-
     ity.

     Only a single MAC address may be stored in flash.	If the address begins with the Altera prefix 00:07:ed and ends in 00 then up to 16
     addresses will be derived from it by adding the unit number of the interface to the stored address.  For other prefixes, the address will be
     assigned to atse0 and random addresses will be used for other interfaces.	If the stored address is invalid, for example all zero's, multi-
     cast, or the default address shipped on all DE4 boards (00:07:ed:ff:ed:15) then a random address is generated when the device is attached.

HISTORY

     The atse device driver first appeared in FreeBSD 10.0.

AUTHORS

     The atse device driver and this manual page were developed by SRI International and the University of Cambridge Computer Laboratory under
     DARPA/AFRL contract (FA8750-10-C-0237) (``CTSRD''), as part of the DARPA CRASH research programme.  This device driver was written by Bjoern
     A. Zeeb.

BUGS

     The atse driver only supports a single configuration of the MegaCore as installed on the Terasic Technologies Altera DE4 Development and Edu-
     cation Board.

     Only gigabit Ethernet speeds are currently supported.

NAME

     altera_avgen -- driver for generic Altera Avalon-bus-attached, memory-mapped devices

SYNOPSIS

     device altera_avgen

     In /boot/device.hints:
     hint.altera_avgen.0.at="nexus0"
     hint.altera_avgen.0.maddr=0x7f00a000
     hint.altera_avgen.0.msize=20
     hint.altera_avgen.0.width=4
     hint.altera_avgen.0.fileio="rw"
     hint.altera_avgen.0.devname="berirom"

DESCRIPTION

     The altera_avgen device driver provides generic support for memory-mapped devices on the Altera Avalon bus.  device.hints entries configure
     the address, size, I/O disposition, and /dev device node name that will be used.  The open(2), read(2), write(2), and mmap(2) system calls
     (and variations) may be used on altera_avgen device nodes, subject to constraints imposed using device.hints entries.  Although reading and
     writing mapped memory is supported, altera_avgen does not currently support directing device interrupts to userspace.

     A number of device.hints sub-fields are available to configure altera_avgen device instances:

     maddr    base physical address of the memory region to export; must be aligned to width

     msize    length of the memory region export; must be aligned to width

     width    Granularity at which read(2) and write(2) operations will be performed.  Larger requests will be broken down into width -sized oper-
	      ations; smaller requests will be rejected.  I/O operations must be aligned to width.

     fileio   allowed file descriptor operations; r authorizes read(2); w authorizes write(2).

     mmapio   allowed mmap(2) permissions; w authorizes PROT_WRITE; r authorizes PROT_READ; x authorizes PROT_EXEC.

     devname  specifies a device name relative to /dev.

     devunit  specifies a device unit number; no unit number is used if this is unspecified.

HISTORY

AUTHORS

     The altera_avgen device driver and this manual page were developed by SRI International and the University of Cambridge Computer Laboratory
     under DARPA/AFRL contract (FA8750-10-C-0237) (``CTSRD''), as part of the DARPA CRASH research programme.  This device driver was written by
     Robert N. M. Watson.

BUGS

     altera_avgen is intended to support the writing of userspace device drivers; however, it does not permit directing interrupts to userspace,
     only memory-mapped I/O.

     altera_avgen supports only a nexus bus attachment, which is appropriate for system-on-chip busses such as Altera's Avalon bus.  If the target
     device is off of another bus type, then additional bus attachments will be required.
