La sous-syst\u00e8me HID-BPF, introduite dans le noyau Linux 6.3, est utilis\u00e9e pour cr\u00e9er des pilotes de dispositifs d'entr\u00e9e sous forme de programmes BPF ou pour traiter divers \u00e9v\u00e9nements dans le sous-syst\u00e8me HID.       <\/p>\n<p>L'outil udev-hid-bpf peut \u00eatre utilis\u00e9 avec le m\u00e9canisme udev pour activer automatiquement des programmes BPF lors de la connexion de nouveaux dispositifs d'entr\u00e9e ou pour charger des programmes BPF manuellement. Deux principales cat\u00e9gories de programmes BPF sont mises en avant pour une utilisation avec udev-hid-bpf : des programmes pour r\u00e9soudre des probl\u00e8mes mat\u00e9riels ou des micrologiciels, et des programmes pour modifier le comportement des dispositifs selon les souhaits de l'utilisateur.    <\/p>\n<p>Dans le premier cas, les t\u00e2ches concernent la r\u00e9solution de d\u00e9fauts et d'erreurs dans les dispositifs, telles que des axes de coordonn\u00e9es invers\u00e9s, des gammes de valeurs incorrectes (par exemple, pr\u00e9tendre qu'il y a 8 boutons au lieu de 5) et des s\u00e9quences d'\u00e9v\u00e9nements illogiques. Dans le second cas, il s'agit de modifier les param\u00e8tres des dispositifs, par exemple, en inversant les boutons \u00e0 l'aide de programmes BPF. Il est pr\u00e9vu que les programmes BPF avec corrections soient progressivement int\u00e9gr\u00e9s dans le noyau principal, ce qui permettra d'\u00e9viter d'ajouter des patches ou des pilotes
