Debugger Command

Definition

 

bm <address> [r w] <Pass

Creates and enables a breakpoint for the

 

count> [v[bwd] <data>]

indicated memory address. Sets the pass count

 

 

 

 

to [count], or 0 if not specified. Defaults to read

 

 

or write, but can be set to read-only or write-

 

 

only using the [r] or [w] options. [v] enables the

 

 

data <data> check capability for [b]yte, [w]ord,

 

 

or [d]ouble word memory accesses. For

 

 

example, “bm 1000 w vb c0” stands for break

 

 

when byte 0xC0 is written to memory address

 

 

0x1000.

 

bs <Vector> <Pass count>

Creates and enables a breakpoint for the indicated software interrupt vector. Sets the pass count to [count], or 0 if not specified.

bx <address> <Pass count>

Creates and enables a breakpoint for the indicated code fetch address. Sets the pass count to [count], or 0 if not specified. Sets the pass count to [count], or 0 if not specified.

c[rw] <Bus> <Dev> <Func>

Performs a PCI configuration [r]ead or [w]rite.

<Off> [data]

 

d[bwdq] <address

Displays the contents of [p]hysical (default) or

range>[,[lp]

[l]inear memory as [b]ytes, [w]ords, [d]ouble

 

 

words, or [q]uad words, or in the previous

 

format if not specified.

e[bwdq] <address> <data

...>[,[lp]

Allows the modification of [p]hysical (default) or [l]inear memory, in [b]ytes, [w]ords, [d]ouble words, or [q]uad words, or in the previous format, if not specified. Data values are entered immediately after the address, separated by spaces.

f[bwdq] <address range>

Fills the given [p]hysical (default) or [l]inear

<value> [,[lp]

memory-range with the indicated value.

 

 

 

g [address]

Begins or will resume CPU execution, setting a

 

temporary execution breakpoint on the given

 

address.

h [on off clear <value>]

Controls history-trace collection. [ON] enables trace collection and clears the current trace buffer; [OFF] disables trace collection, and [CLEAR] clears the current trace buffer. Specifying no arguments, or a value, disassembles the most recent <value> instructions executed.

i[bwd]

<port>

 

Input a [b]yte, [w]ord, or [d]ouble word from

 

 

 

the indicated port.

o[bwd]

<port>

<data>

Output a [b]yte, [w]ord, or [d]ouble word to the

 

 

 

indicated port.

This iteration brings various features and technologies designed to optimize gaming, professional applications, and general computing tasks.

One of the standout enhancements in AMD 4.4.5 is the integration of Smart Access Memory technology, which allows the CPU to access the full graphics memory directly. This feature enhances data flow between the CPU and GPU, leading to improved frame rates and overall performance, especially in memory-intensive games. Users can experience a marked increase in gaming performance without the need for additional hardware upgrades.

Another significant feature introduced is the updated Radeon Software Adrenalin Edition. This software update encompasses optimizations for various games, ensuring that gamers can enjoy a seamless experience with the latest titles. The Adrenalin interface also provides features such as Radeon Chill, which helps reduce power consumption during less demanding scenes, and Radeon Anti-Lag, designed to minimize input lag and enhance responsiveness in competitive gaming.

Additionally, AMD 4.4.5 brings the latest drivers that include important performance enhancements and bug fixes that allow for greater system stability. Regular updates ensure that users have the best experience with their AMD hardware, and it significantly bolsters compatibility with the latest gaming titles and software applications.

AMD's Enhanced Sync technology offers users the ability to eliminate screen tearing and stuttering while delivering smooth gameplay. It dynamically synchronizes the refresh rate of the display with the frame rates produced by the GPU, improving the visual experience significantly.

With the introduction of FidelityFX Super Resolution, AMD continues to bolster its suite of technologies that enhance graphics quality and performance. This feature allows lower-resolution images to be upscaled effectively, making it easier for users to enjoy high-end visuals without taxing their hardware excessively.

In summary, AMD 4.4.5 represents a comprehensive update for users by integrating cutting-edge technologies that cater to a wide range of applications from gaming to content creation. With enhancements across the board, AMD reaffirms its commitment to providing high-performance solutions that keep pace with the ever-evolving technology landscape. Whether for gaming aficionados or professional creators, the capabilities offered in this version make it a significant milestone in the AMD software ecosystem.
