It has two - * modes. In pass through mode then it is an IDE controller. In its smart - * mode its actually quite a capable hardware raid controller disguised - * as an IDE controller. Smart mode only understands DMA read/write and - * identify, none of the fancier commands apply. The IT8211 is identical - * in other respects but lacks the raid mode. - * - * Errata: - * o Rev 0x10 also requires master/slave hold the same DMA timings and - * cannot do ATAPI MWDMA. - * o The identify data for raid volumes lacks CHS info (technically ok) - * but also fails to set the LBA28 and other bits. We fix these in - * the IDE probe quirk code. - * o If you write LBA48 sized I/O's (ie > 256 sector) in smart mode - * raid then the controller firmware dies - * o Smart mode without RAID doesn't clear all the necessary identify - * bits to reduce the command set to the one used - * - * This has a few impacts on the driver - * - In pass through mode we do all the work you would expect - * - In smart mode the clocking set up is done by the controller generally - * but we must watch the other limits and filter. - * - There are a few extra vendor commands that actually talk to the - * controller but only work PIO with no IRQ. - * - * Vendor areas of the identify block in smart mode are used for the - * timing and policy set up. Each HDD in raid mode also has a serial - * block on the disk. The hardware extra commands are get/set chip status, - * rebuild, get rebuild status. - * - * In Linux the driver supports pass through mode as if the device was - * just another IDE controller. If the smart mode is running then - * volumes are managed by the controller firmware and each IDE "disk" - * is a raid volume. Even more cute - the controller can do automated - * hotplug and rebuild. - * - * The pass through controller itself is a little demented. It has a - * flaw that it has a single set of PIO/MWDMA timings per channel so - * non UDMA devices restrict each others performance. It also has a - * single clock source per channel so mixed UDMA100/133 performance - * isn't perfect and we have to pick a clock. Thankfully none of this - * matters in smart mode.
