Tejun Heo 55a8e2c83c [PATCH] libata: implement presence detection via polling IDENTIFY ... On some controllers (ICHs in piix mode), there is *NO* reliable way to determine device presence other than issuing IDENTIFY and see how the transaction proceeds by watching the TF status register. libata acted this way before irq-pio and phantom devices caused very little problem but now that IDENTIFY is performed using IRQ drive PIO, such phantom devices now result in multiple 30sec timeouts during boot. This patch implements ATA_FLAG_DETECT_POLLING. If a LLD sets this flag, libata core issues the initial IDENTIFY in polling mode and if the initial data transfer fails w/ HSM violation, the port is considered to be empty thus replicating the old libata and IDE behavior.
