Hello,
Dear Alan Cox,
Dear Jeff Garzik,
Everyone a happy new year!
We are in stable Kernel 2.6.14.5, year 2006.
Since 1997 people asking on several list for a functional PDC202XX Driver.
Since some years I spend hours and hours finding a solution for a stable driver.
(PDC20269/Promise Ultra133 TX2)
There seem to be none.
There are two Solution:
-The IDE Driver (pdc202xx_new) has still problems with "DMA Timeout".
-The Libata Driver (pata_pdc2027x) seems to be still somewhat experimental.
Unfortunatly I'am not a kernel developper else there would be probably already
a solution ;-)
So what is the Solution for the PDC20269 Ultra ATA Controller?
I would mark this bold on the wishlist for 2006 ;-)
Thanx
=========================================================
Anyone wants a small summary of the halfworking solutions
Way 1 - IDE pdc202xx_new --> /dev/hdxx )
------------------------------------------
Just compile your kernel with a module (or built in):
$make menuconfig
-> Device Drivers
-> ATA/ATAPI/MFM/RLL support
-> ATA/ATAPI/MFM/RLL support (IDE [=y])
-> Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support (BLK_DEV_IDE [=y])
-> PCI IDE chipset support (BLK_DEV_IDEPCI [=y])
-> Generic PCI bus-master DMA support (BLK_DEV_IDEDMA_PCI
->PROMISE PDC202{68|69|70|71|75|76|77} support
$make-kpkg kernel_image
Problems:)
hde: dma_timer_expiry: dma status == 0x60
hde: DMA timeout retry
PDC202XX: Primary channel reset.
hde: timeout waiting for DMA
hde: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hde: drive not ready for command
hde: status error: status=0x50 { DriveReady SeekComplete }
ide: failed opcode was: unknown
hde: no DRQ after issuing MULTWRITE_EXT
hde: status error: status=0x50 { DriveReady SeekComplete }
ide: failed opcode was: unknown
hde: no DRQ after issuing MULTWRITE_EXT
hde: status error: status=0x50 { DriveReady SeekComplete }
ide: failed opcode was: unknown
hdf: DMA disabled
PDC202XX: Primary channel reset.
hde: no DRQ after issuing MULTWRITE_EXT
ide2: reset: success
hde: dma_timer_expiry: dma status == 0x20
hde: DMA timeout retry
PDC202XX: Primary channel reset.
hde: timeout waiting for DMA
or similar
Way 2 - libata (emulates SCSI device) --> /dev/sdxx )
-------------------------------------------------------

http://www.kernel.org/pub/linux/kernel/people/jgarzik/patchkits/2.6/2.6.15-rc4-libata1.patch.bz2
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/testing/linux-2.6.15-rc5.tar.bz2
....(untar)...
$make menuconfig
-> Device Drivers
-> SCSI device support
-> SCSI device support (SCSI [=m])
-> SCSI low-level drivers
-> Serial ATA (SATA) support (SCSI_SATA [=m])
->SCSI_PATA_PDC2027X
Enable PATA as suggested here:
-http://lkml.org/lkml/2004/8/1/100
-http://seclists.org/lists/linux-kernel/2005/May/0503.html
In include/linux/libata.h
#define ATA_ENABLE_ATAPI /* undefine to disable ATAPI support */
#define ATA_ENABLE_PATA /* define to enable PATA support in some
* low-level drivers */
Compile and pray!
With some harddisk it works without problem (seagate 7200.8)
With others Maxtor Maxline III it's not working at all:
Kernel Panics even at boottime:
ATA1: Abnormal status 0x8 on port 0xD...........
or Lost Interrupts...
or the drivers seems to be loaded (lsmod) but there are no
harddiscs under /prov/scsi/... /dev/sdxx
