A minimum\nperiod of 32 is enforced for the rest of the events.\nThe recommended workaround code of the HSW143 is not implemented.\nBecause it only addresses the issue for the fixed counter.

(Para conocer los detalles, consulte https://lore.kernel.org/lkml/87plq9l5d2.ffs@tglx/) El HSW11 requiere un per\u00edodo mayor a 100 para el evento INST_RETIRED.ALL, pero el per\u00edodo inicial en el modo freq es 1. La errata es la misma que la del BDM11, que ha sido compatible con el kernel. Tambi\u00e9n se aplica un per\u00edodo m\u00ednimo de 128 en HSW. HSW143 se refiere a que el contador fijo 1 puede sobrecontar 32 con Hyper-Threading habilitado. Sin embargo, seg\u00fan la prueba, el hardware tiene m\u00e1s problemas de los que indica. Adem\u00e1s del contador fijo 1, se puede observar el mensaje \"la interrupci\u00f3n tard\u00f3 demasiado\" en cualquier contador que se haya armado con un per\u00edodo &lt;32 y dos eventos hayan expirado en el mismo NMI. Se aplica un per\u00edodo m\u00ednimo de 32 para el resto de los eventos. El c\u00f3digo de workaround recomendado del HSW143 no est\u00e1 implementado. Porque solo soluciona el problema del contador fijo. Implica una sobrecarga adicional a trav\u00e9s de la escritura adicional del MSR. Hasta el momento, no se ha informado de ning\u00fan problema de conteo excesivo relacionado."}], "lastModified": "2024-10-04T15:23:35.287", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "FC454BA0-BEF2-4869-B2C2-572AE19D0FE3", "versionEndExcluding": "6.1.110", "versionStartIncluding": "3.11"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E4529134-BAC4-4776-840B-304009E181A0", "versionEndExcluding": "6.6.51", "versionStartIncluding": "6.2"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "ACDEE48C-137A-4731-90D0-A675865E1BED", "versionEndExcluding": "6.10.10", "versionStartIncluding": "6.7"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.11:rc1:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8B3CE743-2126-47A3-8B7C-822B502CF119"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.11:rc2:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "4DEB27E7-30AA-45CC-8934-B89263EF3551"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.11:rc3:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E0005AEF-856E-47EB-BFE4-90C46899394D"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.11:rc4:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "39889A68-6D34-47A6-82FC-CD0BF23D6754"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.11:rc5:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B8383ABF-1457-401F-9B61-EE50F4C61F4F"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.11:rc6:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B77A9280-37E6-49AD-B559-5B23A3B1DC3D"}], "operator": "OR"}]}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
