NAME
sil_dev_config - Apply device/host-specific errata fixups
SYNOPSIS
void sil_dev_config(struct ata_device * dev);
ARGUMENTS
dev
Device to be examined
DESCRIPTION
After the IDENTIFY [PACKET] DEVICE step is complete, and a device is known to be present, this function is called. We apply two errata
fixups which are specific to Silicon Image, a Seagate and a Maxtor fixup.
For certain Seagate devices, we must limit the maximum sectors to under 8K.
For certain Maxtor devices, we must not program the drive beyond udma5.
Both fixups are unfairly pessimistic. As soon as I get more information on these errata, I will create a more exhaustive list, and apply
the fixups to only the specific devices/hosts/firmwares that need it.
20040111 - Seagate drives affected by the Mod15Write bug are blacklisted The Maxtor quirk is in the blacklist, but I'm keeping the original
pessimistic fix for the following reasons... - There seems to be less info on it, only one device gleaned off the Windows driver, maybe
only one is affected. More info would be greatly appreciated. - But then again UDMA5 is hardly anything to complain about
