Description: A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running computation, block while waiting for an event, or read files from the file system. Unlike kernel drivers, a user-space device driver can use other device drivers--that is, access the network, talk to a serial port, get interactive input from the user, pop up GUI windows, or read from disks. User-space drivers implemented using FUSD can be much easier to debug it is impossible for them to crash the machine, are easily traceable using tools such as gdb, and can be killed and restarted without rebooting even if they become corrupted. FUSD drivers don t have to be in C--Perl, Python, or any other language that knows how to read from and write to a file descriptor can work with FUSD. User-space drivers can be swapped out, whereas kernel drivers lock physical memory.-A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running computation, block while waiting for an event, or read files from the file system.

Description: The WinIo library allows 32-bit Windows applications to directly access I/O ports and physical memory. It bypasses Windows protection mechanisms by using a combination of a kernel-mode device driver and several low-level programming techniques. -The WinIo library allows 32-bit Windows applications to directly access I/O ports and physical memory.

Description: This module implements a Linux character-mode device-driver
for the processor s installed physical memory. It utilizes
the kernel s kmap() function, as a uniform way to provide
access to all the memory-zones (including the "high memory"
on systems with more than 896MB of installed physical ram).
The access here is read-only because we deem it too risky
to the stable functioning of our system to allow every user
the unrestricted ability to arbitrarily modify memory-areas
which might contain some "critical" kernel data-structures.
We implement an llseek() method so that users can readily
find out how much physical processor-memory is installed.

Description: A device driver provides a software interface to hardware connected to a computer. It is a trusted part of the operating system. User application programs can access hardware in a well-defined manner, without having to worry about how the hardware must be controlled. For example, a disk driver might hide the fact that data must be written in 512-byte chunks. A driver is a piece of software that becomes part of the operating system kernel when it is loaded. A driver makes one or more devices available to the user mode programmer, each representing a physical or logical piece of hardware. For example, one physical hard disk may be viewed as two logical disks called C: and D: Platform: |
