PATCH: Add support for IT8212 IDE controllers

From: Alan Cox
Date: Sat Jul 31 2004 - 18:26:07 EST


There is a messy scsi faking vendor driver for this card but this instead
is a standard Linux IDE layer driver.

+ * The ITE8212 isn't exactly a standard IDE controller. 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.
+ *
+ * Errata:
+ * Rev 0x10 also requires master/slave use the same UDMA timing and
+ * cannot do ATAPI DMA, while the other revisions can do ATAPI UDMA
+ * but not MWDMA.
+ *
+ * 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
+ * - 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. ATAPI DMA is not supported.
+ *
+ * TODO
+ * - Rev 0x10 in pass through mode needs UDMA clock whacking
+ * to work around h/w issues
+ * - Is rev 0x10 out anywhere - test it if so
+ * - More testing
+ * - Find an Innovision 8401D or R board somewhere to test that
+ * - See if we can kick the cheapo board into smart mode
+ * ourselves 8)
+ * - ATAPI UDMA is ok but not MWDMA it seems
+ * - Better clock strategy
+ * - RAID configuration ioctls
