From 8cdfb29c0cd8018f92214c11c631d8926f4cb032 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Fri, 9 Mar 2007 10:54:42 -0500 Subject: libata/IDE: remove combined mode quirk Both old-IDE and libata should be able handle all controllers and devices found using normal resource reservation methods. This eliminates the awful, low-performing split-driver configuration where old-IDE drove the PATA portion of a PCI device, in PIO-only mode, and libata drove the SATA portion of the /same/ PCI device, in DMA mode. Typically vendors would ship SATA hard drive / PATA optical configuration, which would lend itself to slow (PIO-only) CD-ROM performance. For Intel users running in combined mode, it is now wholly dependent on your driver choice (potentially link order, if you compile both drivers in) whether old-IDE or libata will drive your hardware. In either case, you will get full performance from both SATA and PATA ports now, without having to pass a kernel command line parameter.
