Title (EN) ASYNCHRONOUS UPDATE OF METADATA TRACKS IN RESPONSE TO A CACHE HIT GENERATED VIA AN I/O OPERATION OVER A BUS INTERFACE
(FR) MISE À JOUR ASYNCHRONE DE PISTES DE MÉTADONNÉES EN RÉPONSE À UNE INTERCEPTION CACHE GÉNÉRÉE PAR L'INTERMÉDIAIRE D'UNE OPÉRATION E/S SUR UNE INTERFACE DE BUS
Abstract:
(EN) A cache hit is generated, in response to receiving an input/output (I/O) command over a bus interface. An update for a metadata track is stored in a buffer associated with a central processing unit (CPU) that processes the I/O command, in response to generating the cache hit. The metadata track is asynchronously updated from the buffer with the stored update for the metadata track in the buffer.
(FR) La présente invention concerne une interception cache qui est générée, en réponse à la réception d'une instruction d'entrée/sortie (E/S) sur une interface de bus. Une mise à jour pour une piste de métadonnées est stockée dans un tampon associé à une unité centrale de traitement (CPU) qui traite l'instruction E/S, en réponse à la génération de l'interception cache. La piste de métadonnées est mise à jour de manière asynchrone à partir du tampon avec la mise à jour stockée pour la piste de métadonnées dans le tampon.
