Peter Hutterer, mentenan\u021ba subsistemului de intrare X.Org, care lucreaz\u0103 la Red Hat, a prezentat un nou utilitar udev-hid-bpf, destinat \u00eenc\u0103rc\u0103rii automate a programelor BPF care corecteaz\u0103 problemele cu dispozitivele de intrare cu interfa\u021ba HID (Dispozitiv de Intrare Uman) sau modific\u0103 comportamentul acestora \u00een func\u021bie de preferin\u021bele utilizatorului. Pentru a crea gestionari pentru dispozitivele HID, cum ar fi tastaturile \u0219i mouse-urile, se folose\u0219te subsistemul HID-BPF, ap\u0103rut \u00een nucleul Linux 6.3, care permite crearea de drivere pentru dispozitive de intrare sub form\u0103 de programe BPF sau tratarea diverselor evenimente \u00een subsistemul HID. <\/p>\n

Utilitarul udev-hid-bpf poate fi utilizat \u00eempreun\u0103 cu mecanismul udev pentru a activa automat programele BPF la conectarea de noi dispozitive de intrare sau pentru a \u00eenc\u0103rca manual programele BPF. Se eviden\u021biaz\u0103 dou\u0103 categorii principale de programe BPF pentru utilizarea cu udev-hid-bpf: programe pentru solu\u021bionarea problemelor de hardware sau firmware \u0219i programe pentru modificarea comportamentului dispozitivelor conform dorin\u021belor utilizatorului. <\/p>\n

\u00cen primul caz, se rezolv\u0103 problemele de corectare \u0219i erorile din dispozitive, cum ar fi osii de coordonate inverse, intervale gre\u0219ite de valori (de exemplu, raportarea a 8 butoane \u00een loc de 5) \u0219i secven\u021be de evenimente ilogice. \u00cen al doilea caz, este vorba despre modificarea set\u0103rilor dispozitivelor; de exemplu, prin programele BPF, se pot schimba butoanele \u00eentre ele. Se presupune c\u0103 programele BPF cu corec\u021bii vor fi incluse \u00een timp \u00een nucleul principal \u0219i vor permite evitarea ad\u0103ug\u0103rii de patch-uri sau drivere separate \u00een nucleu.
