Pata support for IDE Controller 82801G ICH7 in Linux 2.6.22

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hi

I have a laptop Asus A6JM with Intel IDE Controller 82801G ICH7
Family. I wanna give a try a new PATA driver instead the old one
(IDE), so I compiled these modules in the Linux 2.6.22 (CONFIG_IDE is
not set) :
# SCSI device support
CONFIG_SCSI=y
CONFIG_SCSI_TGT=m
CONFIG_SCSI_NETLINK=y
CONFIG_SCSI_PROC_FS=y

# SCSI support type (disk, tape, CD-ROM)
CONFIG_BLK_DEV_SD=y
CONFIG_BLK_DEV_SR=m
CONFIG_CHR_DEV_SCH=m

# Some SCSI devices (e.g. CD jukebox) support multiple LUNs
CONFIG_SCSI_MULTI_LUN=y
CONFIG_SCSI_SCAN_ASYNC=y
CONFIG_SCSI_WAIT_SCAN=m

# SCSI Transports
CONFIG_SCSI_SPI_ATTRS=m
CONFIG_SCSI_FC_ATTRS=m
CONFIG_SCSI_ISCSI_ATTRS=m
CONFIG_SCSI_SAS_ATTRS=m
CONFIG_SCSI_SAS_LIBSAS=m

# SATA/PATA driver configuration
CONFIG_ATA=m
CONFIG_ATA_ACPI=y
CONFIG_SATA_AHCI=m
CONFIG_ATA_PIIX=m
CONFIG_ATA_GENERIC=m
CONFIG_PATA_PCMCIA=m

Then I added to /etc/initramfs-tools/modules these modules:
ata_generic, libata, ata_piix
After installing the new kernel and rebooting, the system stopped
showing a message:
"Waiting for root file system..."
Then, after 2 or 3 minutes initramfs shell appeared. So I checked if
82801G controller is supported, and I found this in
linux/drivers/ata/ata_piix.c
/* 82801GB/GR/GH (ICH7, identical to ICH6) */
{ 0x8086, 0x27c0, PCI_ANY_ID, PCI_ANY_ID, 0, 0, ich6_sata_ahci },
/* 2801GBM/GHM (ICH7M, identical to ICH6M) */
{ 0x8086, 0x27c4, PCI_ANY_ID, PCI_ANY_ID, 0, 0, ich6m_sata_ahci },

My question is there a Linux PATA driver for the IDE Controller 82801G
ICH7 Family or is there any plan to support it?

My /etc/fstab looks like:
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
LABEL=ROOT       /               ext3    defaults,errors=remount-ro 0       1
LABEL=BOOT       /boot           ext3    defaults        0       2
LABEL=HOME       /home           ext3
noatime,defaults,errors=remount-ro         0       2
LABEL=SWAP       none            swap    sw              0       0
