Waxaa laga yaabaa inaad rabto inaad awood u yeelato ama aad joojiso awooda Intel Transaction Synchronization Extensions (Intel TSX)^{(Intel Transactional Synchronization Extensions (Intel TSX))} ee soo-saareyaasha soo bandhigaya taageerada processor-ka lagama maarmaanka ah. Maqaalkan waxaan ku tusi doonaa sida, adoo isticmaalaya goobta diiwaanka ee lagu tilmaami doono si loo suurtageliyo ama loo joojiyo TSX .

Waa maxay Kordhinta Isku^{(Synchronization Extensions)} -xidhka Macaamilka ( TSX )

Kordhinta Isku^{(Synchronization Extensions)} -dhafka Ganacsiga ( TSX ) waa kordhinta x86 hab-dhismeedka hab-dhismeedka hab-dhismeedka ( ISA ) kaas oo ku daraya taageerada xusuusta macaamilka ee hardware, dedejinta fulinta software-ka badan ee xadhigga leh ee qufulka. Marka loo eego jaangooyooyin kala duwan, TSX waxay ku siin kartaa ku dhawaad ​​​​40% fulinta codsiyada degdega ah ee culeysyada shaqo ee gaarka ah, iyo 4-5 jeer ka badan macaamil xog uruurin ilbiriqsi ( TPS ).

Kordhinta Isku-xidhka Macaamilka ee^{(Intel Transactional Synchronization Extensions)} Intel ( Intel TSX ) waxay u ogolaataa processor-ku inuu si firfircoon u go'aamiyo in duntu u baahan yihiin inay taxaneyaan qaybo muhiim ah oo quful-ilaalin ah iyo inay sameeyaan taxane taxane ah oo keliya marka loo baahdo. Tani waxay u ogolaanaysaa processor-ku inuu soo bandhigo oo ka faa'iidaysto lacagta isku midka ah ee ku qarsoon codsiga sababtoo ah wada shaqaynta aan loo baahnayn.

Intel TSX waxay bixisaa laba is-dhexgal software si ay u qeexaan gobollada koodka fulinta macaamil ganacsi.

1] Qalabka Quful Elision (HLE)

HLE waa hab-barista hab-raaca ee dhaxal-galka ah ee ku habboon (oo ka kooban horgalayaasha XACQUIRE iyo XRELEASE ) si loo cayimo gobollada wax kala iibsiga. HLE waxaa loogu talagalay barnaamij-sameeyayaasha doorbidaya iswaafajinta dambe ee qaabka caadiga ah ee barnaamijka ka-saarista wadaagga waxayna jeclaan lahaayeen inay ku socodsiiyaan barnaamijka HLE ku shaqeeya^{(HLE-enabled)} ee hardware-ka dhaxalka ah, laakiin waxay jeclaan lahaayeen inay ka faa'iidaystaan ​​awoodaha xannibaadda cusub ee qalabka leh taageerada HLE .

Hardware Lock Elision ( HLE ) hawlaha asaasiga ah waxay khuseeyaan codsiyada C/C++ ee Windows kaliya.

2] Xusuusta Xakamaynta Ganacsiga^{(Restricted Transactional Memory)} ( RTM )

RTM waa hab cusub oo habayn tilmaameed ah (oo ka kooban tilmaamaha XBEGIN , XEND , iyo XABORT ) ee loogu talagalay barmaamijiyeyaasha si ay u qeexaan gobollada wax kala iibsiga si ka dabacsanaan badan tan suurtagalka ah ee HLE .

RTM waxaa loogu talagalay barnaamijyada ka door bida interface dabacsan oo ka door bida qalabka fulinta macaamil ganacsi.

Si aad awood ugu yeelato ama u joojiso Kordhinta Isku-xirka Macaamilka ee^{(Intel Transactional Synchronization Extensions)} Intel ( Intel TSX ) awoodda gudaha Windows 10 , samee kuwa soo socda:

Si aad u damiso ^(disable) Intel TSX iyada oo loo marayo goobta diiwaangelinta:

Ku billow Command Prompt qaab sare leh. ^{(Launch Command Prompt in elevated mode.)}( Guji Start^{(Click Start)} . Nooca CMD^{(Type CMD)} oo isku mar taabo CTRL + SHIFT + Enter combo furaha).

Nuqul ka samee oo ku dheji amarka hoose oo ku dhufo Gelida^(Enter) .

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Kernel" /v DisableTsx /t REG_DWORD /d 1 /f

Dib u bilow kombayutarka si isbedeladu u dhaqan galaan.

How to Enable or Disable Intel TSX capability in Windows 10

You may want to enable or disable Intel Transactional Synchronization Extensions (Intel TSX) capability for those processors that expose the necessary processor support. In this post we will show you how, using the registry setting that will be outlined to enable or disable TSX.

What is Transactional Synchronization Extensions (TSX)

Transactional Synchronization Extensions (TSX) is an extension to the x86 instruction set architecture (ISA) that adds hardware transactional memory support, speeding up the execution of multi-threaded software through lock elision. According to different benchmarks, TSX can provide around 40% faster applications execution in specific workloads, and 4–5 times more database transactions per second (TPS).

Intel Transactional Synchronization Extensions (Intel TSX) allow the processor to determine dynamically whether threads need to serialize through lock-protected critical sections and to perform serialization only when required. This lets the processor expose and exploit concurrency hidden in an application due to dynamically unnecessary synchronization.

Intel TSX provides two software interfaces to specify regions of code for transactional execution.

1] Hardware Lock Elision (HLE)

HLE is a legacy-compatible instruction set extension (comprising the XACQUIRE and XRELEASE prefixes) to specify transactional regions. HLE is for programmers who prefer the backward compatibility of the conventional mutual-exclusion programming model and would like to run HLE-enabled software on legacy hardware, but would like to take advantage of new lock elision capabilities on hardware with HLE support.

Hardware Lock Elision (HLE) intrinsic functions apply to C/C++ applications for Windows only.

2] Restricted Transactional Memory (RTM)

RTM is a new instruction set interface (comprising the XBEGIN, XEND, and XABORT instructions) for programmers to define transactional regions in a more flexible manner than that possible with HLE.

RTM is for programmers who prefer a flexible interface to the transactional execution hardware.

Enable or disable Intel TSX capability in Windows 10

To enable or disable Intel Transactional Synchronization Extensions (Intel TSX) capability in Windows 10, do the following:

To disable Intel TSX via the registry setting:

Launch Command Prompt in elevated mode. (Click Start. Type CMD and simultaneously press CTRL + SHIFT + Enter key combo).

Copy and paste the command below and hit Enter.

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Kernel" /v DisableTsx /t REG_DWORD /d 1 /f

Restart the computer for the changes to take effect.
