See here https://patchwork.freedesktop.org/patch/172771/, currently we only care about huge=within_size. > What other approaches were considered? We also tried https://patchwork.freedesktop.org/patch/156528/, where it was suggested that we mount our own tmpfs instance. Following from that we now have our own tmps mnt mounted with huge=within_size. With this patch we avoid having to roll our own __shmem_file_setup like in https://patchwork.freedesktop.org/patch/163024/. > Was it not feasible to add i915-specific mount options to > mm/shmem.c (for example?). Hmm, I think within_size should suffice for our needs. > > _______________________________________________ > Intel-gfx mailing list > Intel-gfx@xxxxxxxxxxxxxxxxxxxxx > https://lists.freedesktop.org/mailman/listinfo/intel-gfx -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
