(FR) NUMERO DE SERIE DE PROCESSEUR A INVALIDATION D'ACCES A LA LECTURE COMMANDABLE PAR L'UTILISATEUR
Abstract
(EN)
A software method of setting a state in a processor regarding whether a processor number encoded in the processor will be available for reading is described. The method comprises prompting the user to enter an indication whether the processor number should be available for reading by a program. Then, setting a state to inhibit the processor number from being read by a program if the indication indicates that the processor number should not be available for reading by the program. For one embodiment, the method further includes testing the indication if a request for the processor number is received, and releasing the processor number if the indication indicates that the processor number is available.

L'invention concerne un procédé, commandé par logiciel, d'établissement d'un état dans un processeur, permettant ou empêchant l'accès à la lecture d'un numéro de processeur codé dans le processeur. Le procédé comprend l'annonce d'un message invitant l'utilisateur à entrer une indication concernant l'éventuelle autorisation d'accès à la lecture du numéro de processeur par un programme, puis, dans le cas où l'indication n'autorise pas l'accès à la lecture du numéro de processeur par un programme, l'établissement d'un état empêchant l'accès à la lecture du numéro de processeur par un programme. Dans une réalisation, le procédé comprend également la vérification de l'indication en cas de réception d'une demande concernant le numéro de processeur, puis la communication du numéro de processeur si l'indication autorise l'accès à la lecture dudit numéro.
