hi,all I want to enable cache flushes for my hd on s3c2410 & linux-2.6.20, ide_id_has_flush_cache() return 0 because cfs_enable_2 is 0x201, while it needs 0x3000, I found out that 0x201 was from 512 bytes of id info,implemented in static void ata_input_data(ide_drive_t *drive, void *buffer, u32 wcount) the question is, does it mean my hd does not support cache flush on hw layer? if not, how to enable? thanks for the coming help!
