[Bug 218200] New: Acer Aspire 3682: hdd connected to ICH7 limited to UDMA33
https://bugzilla.novell.com/show_bug.cgi?id=218200
Summary: Acer Aspire 3682: hdd connected to ICH7 limited to
UDMA33
Product: SUSE Linux 10.1
Version: Final
Platform: 32bit
OS/Version: SuSE Linux 10.1
Status: NEW
Severity: Major
Priority: P5 - None
Component: Kernel
AssignedTo: kernel-maintainers@forge.provo.novell.com
ReportedBy: jakub007@go2.pl
QAContact: qa@suse.de
Kernel configures hdd on Acer Aspire 3682 to use UDMA33, while drive is UDMA100
capable. The reason is reg 0x54 set to 0 (maybe broken BIOS).
Here is fix:

There are two types of IDE cables - 40-conductor and 80-conductor. 40c can do upto 33. If you wanna go higher, you need 80c cable. IDE controllers have cable detection mechanism and BIOS initializes cable type according to detected type. Situation is a bit different on laptops because the vendors control cable length. They use 40c cable but cables are usually *really* short, so they can do UDMA/100 no problem. Hardware is all the same with any other 40c system, so UDMA/33 limitation is applied unless specifically overridden. Vendor drivers do such things and recent libata laptop patches do the same. So, no, it isn't safe to override IOCFG whenever it's zero. You need to check devid, subvendor and subdevid before applying such override. Now that IDE has entered life-support mode, the motivation to improve piix driver is quite low. (IDE drivers in general are pretty scary to look at too). Hannes, do we need such laptop special handling in drivers/ide? Or can we just move on to libata? I'm voting strongly for the latter. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

https://bugzilla.novell.com/show_bug.cgi?id=218200 ------- Comment #6 from jakub007@go2.pl 2006-11-18 08:51 MST ------- With updated kernel for SUSE 10.1 you would have to deal with device name change from /dev/hda to /dev/sda. If you can handle this without making system unbootable I would vote for libata. Also I wouldn't like to broke smartctl - I'm not up to date, but do we have ATA pass-thru in SUSE kernel? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I've just checked ASUS A6K with SiS chipset and its hdd also runs in UDMA33 mode -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I doubt that Sun has got list of laptops with short 40c cable. Why can't we have this done normal standard way like in other systems?: Start with DMA mode = max. DMA supported by IDE controller, if the drive does not support it, step down, etc. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

JJ, what we're doing is the 'usual' way. If you skip cable detection, transmission errors are bound to happen; unfortunately, not all such errors can be recovered gracefully. Some controllers lock the whole system up hard under certain circumstances. I'm pretty sure Windows drivers carry list of short 40c cables. Dunno what Solaris does tho. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
