I-Intel iphinda iyihlanganise nokunye ukuba sengozini okuthinta nokuphathwa kwememori ebonakalayo

I-Microprocessor chip ibheke phansi

Okungaqondakali iphutha lokuphepha kuthinta zonke izakhiwo zesimanje ze-Intel CPU ezinamandla wokusebenzisa inkumbulo ebonakalayo. Ukwakhiwa kabusha ngokuphelele kwalezi zakhiwo zehadiwe mhlawumbe kuyadingeka ukuxazulula le nkinga ngokuphelele, kepha ama-patches asevele asetshenzisiwe ukuchibiyela kusuka kusoftware futhi ama-patches asevele efika ku-kernel ye-Linux. Endabeni yezinhlelo zeMicrosoft ezisuselwa kwiWindows NT, zaqala ukuxazululwa ngoNovemba wangonyaka odlule. Elinye icala elifana naleli ebesinalo ngokulimazeka okwaziwayo okuthinta izinkumbulo ze-RAM futhi lelo laziwa njengeRowhammer, lifaka engozini ezokuphepha.

Hhayi-ke, manje le nkinga entsha ingathinta izindawo zokubona izinto ezijwayelekile futhi ezisetshenziswa njengezinsizakalo ze- I-Amazon Web Services (AWS) EC2 kanye naleyo yeGoogle Compute Engine phakathi kwabanye. Iqiniso liwukuthi inkinga ayinzima kakhulu, kodwa umthelela ubanzi ngenxa yenani elikhulu lezakhiwo ezithinta, ngaphezu kweqiniso lokuthi ukuxazulula inkinga usebenzisa isofthiwe kuyinkimbinkimbi. Ngokucacile, inkinga etholakala kuleli phutha le-Intel ilele ku-LWN, amathebula okuhlukanisa amakhasi e-kernel, angenelela ekuphathweni kwememori yi-kernel. Bese sithola a Isixazululo esiyinkimbinkimbi uma kwenziwa ngesoftware futhi lokho bekungasho izixazululo ezihamba phambili futhi ngakolunye uhlangothi kufanele siye empandeni yenkinga futhi sakhe kabusha i-hardware, ikakhulukazi izakhiwo ezithintekayo ezivumela ukuphatha lolu hlobo lwememori. Lokho akushibhile noma kuyashesha futhi, ngoba kuzofanele silinde izizukulwane ezintsha zehadiwe obekuzodingeka ukuthi sizithole.

Kepha ukubuyela kusixazululo sesoftware, okungukuthi, ngokuchibiyela, akukuhle futhi njengoba kungakuthinta kakhulu ukusebenza. I-CPU yethu ingaba nokulahleka okukhulu kokusebenza, kuze kufike ku-50%. Kungani? Ukuze uyixazulule, kuzodingeka ukuthi kwenziwe ikhodi ukuze ikwazi khipha imemori ye-TLB (I-Translation Lookaside Buffer), i-cache esheshisa ukusebenza kakhulu ngokuthola ngokushesha lapho idatha nemiyalo kutholakala kwimemori ebonakalayo yohlelo. Kepha ukuyisusa njalo lapho i-kernel iqala futhi ngaso sonke isikhathi lapho ikhodi yomsebenzisi iqala ukwenziwa kwayo, ngoba inkinga iyaphawuleka ...
