У меня тоже процессор AMD Phenom II x4. Модель не помню. Какая у тебя видеокарта и сколько оперативной памяти? Всё делал как в видео?

Кастыль, не играбельно. Через N-ое время наичнает безбожно тормозить.

P.S: id игры при новом запуске меняется.
P.S: AMD Phenom II X4 970, 16 GB памяти, MSI R7 265 2GB

P.S: Не мучайтесь, делайте возврат денег.

Круто конечно, что и лицензия запускается через эмулятор, но кто-нибудь в курсе собираются разработчики это поправлять?

Ведь по факту толку от того что они юзают SSE4a никакого — лучше бы оптимизировали игру и поправили местами управление — местами очень неудобно.

Intel® Software Development Emulator

已发布: 06/15/2012 最后更新时间: 02/09/2021

Product Overview

This emulator is called Intel® Software Development Emulator or Intel® SDE, for short.

The current version is 8.63 and was released January 18, 2021. This version corresponds to the programmers reference 319433-042 available on the Intel Instruction Set Architecture Extensions page. The Intel® SDE release notes are here. This is a minor update release to the version that already has:

• Emulation support for the additional Intel® Advanced Vector Extensions 512 (Intel® AVX-512) instructions present on some future Intel® processors.
• Emulation support for the vector instructions for deep learning present on the next Intel® processors.
• Emulation support for the Intel® Advanced Matrix Extensions (Intel® AMX) present on some future Intel® processors.

Intel® SDE continues to support the features from previous releases:

• Intel® Streaming SIMD Extensions 4(Intel® SSE 4), AES and PCLMULQDQ and the Intel® Advanced Vector Extensions (Intel® AVX)
• Intel® AVX2, RTM, BMI1 and BMI2 instructions being introduced on the 4th Generation Intel® Core™ processor family formerly known as Haswell microarchitecture.
• The ADOX/ADCX instructions being introduced on the 5th Generation Intel® Core™ processor family formerly known as Broadwell microarchitecture.
• Support for Restricted Transactional Memory introduced on the 4th Generation Intel® Core™ processor family formerly known as Haswell microarchitecture.
• Support for the Intel® Secure Hash Algorithm (Intel® SHA) extensions present on the Intel® Atom™ processor formerly known as Goldmont microarchtiecture.

Related useful materials:

• More information about the Intel® SHA extension is available here and includes a sample test application.

Intel is releasing this Intel® SDE so that developers can gain familiarity with our upcoming instruction set extensions. Intel® SDE can help ensure software is ready to take advantage of the opportunities created by these new instructions in our processors. We hope that developers will explore the new instructions using the currently available compilers and assemblers.

Intel SDE is built upon the Pin dynamic binary instrumentation system and the XED encoder decoder. Pin controls the execution of an application. Pin examines each static instruction in the application approximately once, as it builds traces for execution. During this process, which is called instrumentation, for each instruction encountered Pin asks Intel® SDE if this instruction should be emulated or not. If the instruction is to be emulated, then Intel® SDE tells Pin to skip over that instruction and instead branch to the appropriate emulation routine. It also tells Pin how to invoke that emulation function, what arguments to pass, etc.

Intel SDE queries CPUID to figure out what features to emulate. It also modifies the output of CPUID so that compiled applications that check for the emulated features are told that those features exist.

Intel® SDE comes with several useful emulator-enabled Pin tools and the XED disassembler:

• The basic emulator
• The mix histogramming tool: This Pin tool can compute histograms by any of: dynamic instructions executed, instruction length, instruction category, and ISA extension grouping. This tool can also display the top N most frequently executed basic blocks and disassemble them.
• The debugtrace ASCII tracing tool: This versatile tool is useful for observing the dynamic behavior of your code. It prints the instructions executed, and also the registers written, memory read and written, etc.
• The footprint tool: This simple tool counts how many unique 64 byte chunks of data were referenced during the execution of the program.
• The XED command line tool which can disassemble PECOFF or ELF binary executables.

Installation

Download and unpack the appropriate kit for your platform. Set your PATH variable to point to that directory. You can also refer to the tools in the kit using full or relative paths. Do not rearrange the files or subdirectories in the unpacked kit. If you want to move the kit directory, move everything.

Windows*: If you are using Winzip, it puts the proper permissions on the unpacked files. However, if you are using Cygwin’s tar command to unpack the Windows* kit, you must execute a «chmod -R +x path-to-kit» on the unpacked kit (where «path-to-kit» is the unpacked kit directory name).

Linux*: On some distributions, you must disable «SE Linux» to allow Intel® SDE to work. On Ubuntu systems, you must disable yama as described below.

Mac*: Intel SDE is using the MACH taskport APIs. By default, when trying to use these APIs, user-authentication is required once per a GUI session. In order to allow PIN/SDE run without this authentication you need to disable it. This is done by configuring the machine to auto-confirm takeover of the process as described below.

Running Intel® SDE

This is the pattern for running SDE:

The double dash («—«) is important. Options to SDE go before the double dash. Square brackets denote optional arguments.

Important options are the short and long help messages. To see the short help message:

And to see the very long help message:

In the help messages, the command line options are often displayed using underscores between words, but dashes may be used instead of underscores. Often the Intel® SDE help messages and this web page will refer to command line options as «knobs» for historical reasons. The short help message contains some top level analysis tools knobs as well as the list of supported CPUs.

Emulate Everything Mode

• Windows*: A file called sde-win.bat is provided in Windows* that runs a cmd.exe window under the control of Intel® SDE. You can make a shortcut to it and place that shortcut on your desktop. Everything run from that window will be run under the control of Intel® SDE, so you may experience a slow down even when you are not emulating anything. All it really does is:
• OS X* or Linux*: You can run your favorite shell under the control of Intel® SDE:

And everything you run from there will be run under the control of Intel® SDE.

Running the Histogram Tool

To generate the instruction mix histograms by opcode (XED iclass, the default) or instruction form (iform). As of version 4.29, the instruction length and instruction category histograms are always included.

Notes:

• The ISA extension histogram is also always computed and printed as star-prefixed rows in the histograms. ISA extensions are things like (BASE, X87, MMX, SSE, SSE2, SSE3, etc.). This is useful to see which instruction set extensions are used in your application.
• The dynamic statistics are recorded and emitted several ways: (1) per-thread, (2) per function per thread, and (3) summed for the entire run. Instruction counts by function are also emitted if symbols are found for the application.
• The output is written to a sde-mix-out.txt file in the current directory. The output file name can be changed using the -omix option:
• The top 20 basic blocks are always printed in the output with their execution weights.
• «-top_blocks N» will allow you to change 20 to N that you specifiy.
• Iforms: «Iform» is the XED term for variants of instructions. In a simple world they would be things like reg/reg or reg/mem, but things are more complicated in general. The iform names come from XED. Consider them experimental and subject to change. To see histograms by the more detailed iforms, use the «-iform» command line option.
• There are many command line options for the mix tool:

Output: in sde-mix-out.txt (default file name)

Mix Accounting

The rows in the mix output histograms come in two flavors. The rows that begin with «*» are meta-categories which sum up the data in different ways. Here are descriptions of some of the meta categories:

*scalar-simd anything with the XED_ATTRIBUTE_SIMD_SCALAR including AVX and SSE operations. The instructions that operate on one vector element and whose iclass name ends with «SS» or «SD» have this attribute.
*sse-scalar any SSE instruction with the XED_ATTRIBUTE_SIMD_SCALAR
*sse-packed any SSE instruction without the XED_ATTRIBUTE_SIMD_SCALAR

Checking For Bad Pointers and Data Misalignment

Two of the more common errors when bringing up new code are (a) dereferencing bad pointers, either null pointers or pointing to inaccessible memory and (b) misaligned data accesses. Intel® SDE has features to help identify these situations in programs.

The options for the pointer checker are:

The alignment checker can give profiles of data alignment throught the program as well as when and where data accesses are misaligned.

Running the ASCII Tracing Tool

The output is written to a sde-debugtrace-out.txt file in the current directory by default. There are many options. Run ‘sde -debugtrace -thelp’ Pin tool option to see the choices. It prints the registers and flags modified by each instruction. It also prints the memory values read/written.

Using the Chip-check Feature

Starting with version 2.94, Intel® SDE includes a filtering mechanism to restrict executed instructions to a particular microprocessor. This is intended to be a helpful diagnostic tool for use when deploying new software. In the output of «sde -thelp» there is a section describing the controls for this feature:

To list all the chips that Intel® SDE knows about, you can use «sde -chip-check-list». To limit instructions to the processor codenamed Westmere, use «sde -chip-check WESTMERE — yourapp». By default, Intel® SDE emits warnings to a file called sde-chip-check.out and also to stderr (if the application has not closed stderr). This behavior can be customized using the above knobs.

Using Intel® Transactional Synchronization Extensions (Intel® TSX)

Intel® TSX supports emulation of Restricted Transactional Memory (RTM) technology as of version 6.1.

The RTM options are as follows. You can see this in the long help output emitted when running «sde -long-help».

(As in all SDE knobs, you can use dashes instead of underscores.)

For RTM, there are 4 different modes for rtm, disabled, abort, full and nop. Disabled is the default because emulating RTM in software is very slow. The abort modes always aborts upon executing xbegin. Full is the RTM enabled mode. And NOP treats the RTM instructions like NOPs. Please see this blog posting for more information on how to use RTM.

Intel SDE provides statistics about the use of RTM during the execution of your program:

Here are some simple examples of running with Intel® TSX:

And here is a more complete example of running an RTM on Windows*

Running XED Disassembler

The above command writes dis.txt.
See the help message (-help) for many options.

XED prints the ISA Extension for every instruction. This is useful for finding new instructions in your code. Example Output:

Debugging Emulated Code

Intel SDE provides support for debugging application with emulated code. A description on using the system debugger is available here.

Intel AVX and Intel SSE Transition Checking

It is recommended that a VZEROALL or a VZEROUPPER be inserted between code that uses Intel SSE and code that uses 256b Intel AVX instructions. Intel SDE can check for Intel SSE instructions followed by Intel AVX instructions without an intervening zeroing instruction, and vice versa.

Use the «-ast» Pin tool knob

Use the «-oast filename» to specify a filename other than «avx-sse-transition.out» . When using the «sde» driver -oast implies -ast.

Output: in «avx-sse-transition.out»

​In this case, the program counter locations implicated the isnan() calls in the following code:

Using Intel SDE For Program Record and Replay

Intel SDE now incorporates the pinplay technology for program record and replay.

Information on this technology is available in the pinplay article Program Record/Replay Toolkit

The basic command for creating a pinball (pinplay checkpoint) is:

The basic command for replaying a pinball (captured from a 64 bits application) is:

All the other Intel SDE knobs like -mix are available also in the replay mode.

Using Intel SDE For Emulating Control-flow Enforcement Technology

Intel control-flow enforcement technology (CET) was described in a technology preview in the ISA extensions page.

Intel SDE now provides a way to emulate the user space aspects of this technology and the readiness of the software compiled with CET stack checks or CET indirect branch checks. Intel® SDE supports running the application on existing hosts (Linux and Windows) and provides ways to reduce false reports due to running with the system legacy runtime libraries (which were not compiled with CET).

Instructions for running application under Intel SDE with control-flow enforcement technology are available in the article, Emulating Applications with Intel SDE and Control Flow Enforcement Technology.

System Configuration

Linux

On Ubuntu system the yama feature disables processes from using ptrace attach to the parent process. Intel SDE is using this feature to inject itself into the process. To disable yama on the system run the following as root:

This change takes effect until the next reboot. To make this change permanent add it to the init scripts of the system.

Intel SDE is using taskport API to inject itself to the application process (whether in attach mode or in launch mode). This results with a popup window to confirm that it is allowed to take control of another process. This happens only at the first time that Intel® SDE is used on a GUI session. However, when running on non-GUI sessions, (e.g. SSH session) the popup will never show up and it will fail immediately. To cope with this issue, a one time configuration is needed to be performed on the machine so the OS will not try to show this popup and will auto-confirm the takeover of the process.

You need to perform the following procedure:

System Integration Protection

System Integrity Protection is a security technology in macOS* El Capitan (10.11) and later, which restricts the root user account and limits the actions that the root user can perform on protected parts of the Mac operating system.
System Integrity Protection includes protection for these parts of the system:

In order to run SDE on applications which are protected by the system-integrity, you must disable it.

For disabling/enabling SIP, please follow the instructions in the following link (End of the article): How to modify SIP

Frequently Asked Questions

How do I download Intel SDE?

Intel® SDE is available on the Download Page.

How do I ask questions and get support?

The Intel AVX and CPU Instructions Forum has been set up to address questions. Intel engineers will be monitoring and available to answer user questions.

Q: What are the system requirements?

Intel® SDE will run on IA-32 or Intel® 64 processors running Windows or Linux or OS X operating systems.

What are the CPUID requirements?

Pin, and thus Intel SDE requires a Pentium 4 or later processor.

What about running IA-32 architecture applications on Intel® 64 processor platforms?

This is supported.

What about precise SSE exception handling in MXCSR?

Intel SDE tries to accurately set the MXCSR exception flags, but unmasked floating point exceptions are not supported.

What happens when my program dereferences inaccessible memory for emulated instructions?

Intel SDE will crash. You can use «sde -ptr-check — your app» to get a more verbose error message. Alternatively, you can use «sde -trace-execute — your app» to get dump of the instructions executed in your task to find out what instruction was last executed. Then you can use «sde -debugtrace — your app» to look for the last write to the registers involved in the effective address computation for that last executed instruction.

Does Intel® SDE handle cygwin /cygdrive/c paths or symlinks?

No, because Pin does not handle them, Intel® SDE cannot handle them.

Where can I learn more about Pin?

Pin — A Dynamic Binary Instrumentation Tool and the Groups.io group «pinheads». The release notes for Pin are available here. It provides additional information and restrictions about using Intel SDE, which is built on Pin.

Where can I learn more about mix and debugtrace?

The basic sources for debugtrace and mix are available in Pin kits on the Pin website. I’ve modified them slightly to invoke Intel® SDE and to print out the new registers.

What are the licensing terms?

How can I get Intel SDE to work on Ubuntu 10 or later?

There is a known problem of using Intel® SDE on Linux* systems that prevents the use of ptrace attach via the sysctl /proc/sys/kernel/yama/ptrace_scope. In this case Pin is not able to use its default (parent) injection mode. To resolve this, execute the following echo command as root. (SDE does not need to run as root.)
$ echo 0 > /proc/sys/kernel/yama/ptrace_scope
