From 7da79312830e6d9b3f6ee06b86c3a35caba2f6e7 Mon Sep 17 00:00:00 2001 From: Brett Russ Date: Thu, 1 Sep 2005 21:53:34 -0400 Subject: [PATCH] libata: fix pio_mask values (take 2) ata_get_mode_mask() uses bits 3 and 4 in the pio_mask to represent PIO modes 3 and 4. The value read from the drive, which reports support for PIO3 and PIO4 in bits 0 and 1, is shifted left by 3 bits and OR'd with 0x7 (which then corresponds to PIO 2-0 in libata). Thus, the drivers below need adjustments to comply with the way pio_mask is used. I changed the masks from the commented values to all support PIO4-0, since the spec mandates that PIO0-2 are supported and there's no reason not to support PIO3 IMO.
