Pata support for IDE Controller 82801G ICH7 in Linux 2.6.22

Pata support for IDE Controller 82801G ICH7 in Linux 2.6.22

[Bartek]

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>

Hi again,

Michal Piotrowski (thanks Michal :)) took me a private notice that I
should send output of lspci -n instead of lspci -vvv, so here it is
(part of, I hope that's enough):

00:1f.1 0101: 8086:27df (rev 02)

Ok, this controller is supported.

Did you forgot about CONFIG_PATA_MPIIX=y?

I did not mention it in my previous message, but I made a few
different compilation of Linux, also with that option (compiled
directly to the kernel and as a module). And it did not work. But, to
be sure I recompiled kernel again with CONFIG_PATA_MPIIX=y and it did
not work. So, if the controller is supported, where is the problem?

MPIIX is for early Intel laptop (pentium era).

If the chip is in AHCI mode then CONFIG_AHCI may be what is missing

I made a few tests. First I booted my comp with Ubuntu Live Feisty
Fawn, checked modules which are loaded, and interesting ones are:
ata_piix, ata_generic, libata, scsi_mod, sg, sr_mod, sd_mod
ls /dev/sda* showed:
/dev/sda{1,2,3,4}.
So I recompiled the kernel with these options (marking all these
drivers as a modules, in the previous situation they were modules, as
well as compiled directly), and tried to boot. Nothing worked. The
same situation appeared: Waiting for root file system...
Second, I installed a Debian distribution kernel
(linux-image-2.6.22-1-686) and booted from it. It used an old IDE
driver, not PATA. So again no success.
According to AHCI, my chip is rather not that kind. Ubuntu does not
load any AHCI modul. In my previous kernel compilations I tried that
option as well. It did not work.

This sounds like a problem I ran into when I tried to boot a 2.6.21 kernel 
using libata with Ubuntu Edgy installed. The init script on the initramfs 
failed at the same point - not a problem with the drivers, but a problem with 
what the scripts are looking for. I'd suggest looking at the scripts on the 
initramfs - its been my experience that they are the culprit and not the 
kernel itself.
