Hello all,
I have been stuck on a strange problem since last 4 weeks. The problem has to do with enabling DMA for my AMD CS5536 chipset. Here is my problem description:
The output for the IDE controller driver(AMD74xx) shows the following in dmesg:
#dmesg
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
AMD5536: IDE controller at PCI slot 0000:00:0f.2
AMD5536: chipset revision 1
AMD5536: not 100% native mode: will probe irqs later
AMD5536: 0000:00:0f.2 (rev 01) UDMA100 controller
AMD5536: neither IDE port enabled (BIOS)
This shows that the driver is properly recognized(AMD5536) for the device (AMD CS5536 Geode Companion chipset). But the culprit is the line "neither IDE port enabled (BIOS)" which usually suggest that DMA will not work and which turns out to be true because my hdparm shows the following:
#hdparm /dev/hda
/dev/hda:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 8355/16/63, sectors = 8421840, start = 0
Clearly the DMA is turned off.
Now when I try to enable the DMA I get the following error message:
#hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
Although when you try to print the general information for the drive it shows that it is using udma2(which is what I wanted) but I know it is reporting false as there are tons of similar observation on the Internet and it is believed to be false output:
#hdparm -i /dev/hda
/dev/hda:

Ok, I have compiled my driver (AMD and nVidia PCI chipset option) INTO the kernel and NOT AS a module but still this happens.
Here are some suggestions that I have got from people about this problem:
1. Bus Master is not enabled in the BIOS
2.Referring to the output of the dmesg pasted above here is another response:
"Thats what you want to see - that shows that the driver installed, which means that it identfied the part correctly, but the ports were not configured probably because the enable bits have been turned off in the PCI config space. Try restoring the defaults in your BIOS setup screen and trying again."
http://geode.insideo.net/info-linux_archives/msg00192.html
3.DMA_BASE address is not getting initialized properly.
4. May be a kernel issue?
Here are some details of my system:
1. AMD Geode GX2/CS5536 processor
2. Debian (testing)
3. Debian Kernel 2.6.16
Here are my questions:
1. Now is there any way(setpci,scanpci,lspci,etc) by which we can enable the IDE port which the kernel is complaining because it thinks that it is disabled? Although DMA works fine on Windows XP
2. Also from where can I know which register is responsible for the IDE port? Is there any standard address in the PCI configuration space for the IDE/DMA register?
3. Is this some issue which can be only solved at BIOS level? Can we change the values of the PCI device register through linux?
Any help will be highly appreciated. Please help.
Thanks
Below I am attaching some detailed output of some commands like lspci,dmesg.

Your BIOS is just heinously b
Your BIOS is just heinously broken.
What board is this? Who did you buy it from? Do they have an updated BIOS?
You *need* to get an updated BIOS from the board manufacturer. From you ACPI dump in dmesg, it looks like General Software is your BIOS provider. Ask first your board provider for a new BIOS, then ask General Software.
There are several things wrong in this dump:

The first problem you complain about is:
AMD5536: neither IDE port enabled (BIOS)
This is because offset 40, bit 2 is not set. Even if you set that manually somehow, you have even *more* problems. Offsets 48, 4c, and 50 all should have values in them, as they are the timing registers.
You could try and take the common Linux tack of "the BIOS is broken, let's fix it", but the better answer is to get a good BIOS. Your board vendor should give you one.
What are these registers
First of all thanks a lot for replying. to be honest this is one of the best detailed reply that I have got so far which actually makes sense. Now as you mentioned that offset 40 bit 2 is not set, what is that register called? is there any reference manual which explains what registers are there and what are they called in the PCI config space of IDE controller.
Also I have a another similar board with chipset CS5535 instead of CS5536 and on that the DMA works fine although it uses a driver specifically for "AMD CS5535 chipset" under Kernel config. The PCI dump for the IDE controller is almost the same specially the rows from 10 to 50. So does that mean that different IDE controller has different bits to enable the DMA?
Also can you tell me how can I set the bit 40 as you suggested. An example would be really good. Also what do I do about the timing registers?
Thanks a lot once again.....You are awesome dude.
Hm, you didn't read my reply
Hm, you didn't read my reply closely.
What board is this? Where did you buy it? Did you ask them for a new BIOS?
You can look at the AMD 8111 data sheet (its on the web) to see where the registers are defined. The 5536 data sheet is also available on AMD's website.
5535 and 5536 have completely different IDE controllers. The config space and timing registers are all different.
Let me be clear, since you obviously didn't get it from my earlier post: Don't waste your time trying to fix up the config space. It is just wrong.
Get a new BIOS.
This is a Geode GX2 Processor
This is a Geode GX2 Processor board with CS5536 chipset. For the BIOS I think it will be some time before General software gives the new BIOS. And I wanted to get the DMA working on this board as soon as possible for some project and hence I was wondering if anything can be done at the OS/Kernel level.
I have the BIOS code for this board and I am not a BIOS expert in any sense but if you can give me some guideline as to what needs to get changed(like what values should be set in which registers) in BIOS in order to get the DMA working then I can give it a shot? Also if you think that it will require a lot of work and will be quite complicated this then I have no other option then to wait for a new BIOS from General Software.
Again thanks a lot for all your help.
anyone???

This is low level - if you need to ask, don't do it
At this low level, if you need to ask the Internet for help, you're badly out of your depth; pester your vendor for a BIOS update, as you're likely to end up in a bad state if you try and fix things yourself. You can end up with a board that's not bootable on some chipsets if you poke registers you shouldn't, and you're at risk of (e.g.) accidentally poking the registers that let you wipe the BIOS ready for a reflash.
Basically, get your vendor to help. You paid them, they've got to deliver.
Thank you guys for your sugge
Thank you guys for your suggestion. I have requested the BIOS vendor to give a new BIOS. But I have something to add. Actually for my own knowledge I would like to know what values should in the Base Registers in the PCI configuration space of a particular device. Are these values same for all the IDE controllers? Also from where I can find what values should the registers have when the device is working properly. Is there some sort of manual for the device which explains the registers and the values that they should contain?
There is a manual for the device
The values differ from PCI device to PCI device; some are defined in the PCI spec, but most of the registers are only defined in the device's data sheet. If you want to find out what values should be in the config registers for a device, grab the PCI specification, and the datasheet for that device, and you should be able to work it out from there.
You purchase the PCI spec from the PCI-SIG, who define it; individual parts of the PCI spec are $100 in hardcopy, while a CD with PDFs of the entire set of PCI specs is $1500. You'll then need to contact the device manufacturer, and ask them how you get the datasheet for the device.
Difference between PCI specification and PCI device datasheet
Thanks franz a lot!!! Actually I have an extension question based on what you replied. You said to get the PCI spec + Device's Data Sheet. What is the difference in information between the two? Is PCI spec a kind of generic information about the standard Registers and Data Sheet is specifically for that particular PCI device?
Thanks
You're out of your depth - STOP NOW
At this point, you are completely out of your depth. I must reiterate that if you have to ask this sort of question, you simply do not yet have the knowledge or experience to avoid completely trashing your board beyond repair. As a result, this is the final question I am going to answer on this topic.
The PCI spec defines PCI. The device's data sheet will reference PCI in various ways, depending on the device, and tell you how to handle the device. Between the device's data sheet, and the relevant parts of the PCI spec, you will be able to determine everything you need to know, from the physical characteristics of the device (what temperatures it can handle, how large it is, what pins it has) through the electrical characteristics (what sort of signals it can handle, what sorts of current and voltage levels it copes with etc), through to the software interface (which registers do what, how to program the registers, how to read and write data to and from the chip etc).
I must repeat that poking at this low level without a colleague able to help you is dangerous. If your colleagues are not able to help (e.g. because this is a personal project), find a local higher education institute or suitable hobby group, explain what you think you need to know, and go on courses to teach you the basics of hardware interfacing.
Alright
Alright I got your message and I think your point is very valid. I have already asked my vendor to give me a new BIOS. The only mystery that remains is even if the BIOS is broken how come DMA mode is working on Windows XP? I always thought Windows XP talks to BIOS to get some information about the resources allocated to the devices.
Anywords on this.
thanks
