IT821x: no DMA since 2.6.21
Hi!
Since 2.6.21 I have a problem with the it821x driver on my ITE 8212
controller.
Now I saw some updates to it821x in 2.6.22-rc1 and gave that a try, but
the problem persists.
It seems that DMA is broken on it8212 somehow since the merge of
the it8213 driver.
dmesg shows some BUG DMA OFF:

Until 2.6.20 (since 2.6.10) the driver worked quite fine, but since
2.6.21 moving/copying files from/to any drive on the controller is
a) really slow,

This has not been a problem before. hdparm -tT showed something around

Back on 2.6.20 - here is some output from the working driver.
There is actually no difference in dmesg:

I've had multiple reports of this. I would recommend you use the libata driver. IT821x hasn't changed over the past few releases so its someting in the core IDE code that broke it [note it might not of course be that the problem is in the core code..]. I have no plans at this point to debug the old IT821x driver due to time constraints, and if anyone wants to have a crack at debugging this and fixing it go for it. BTW: I also note you have the controller in smart mode but are not using the hardware raid functions. In that situation it generally runs faster (and does CD-ROM) if you flash the ATAPI firmware to the controller or boot with the noraid option it8212.noraid=1 Alan Hi Alan, thanks for the suggestion. I already tried pata_it821x and it failed to recognize the second harddisk hdf. I use the controller only for additional harddrives, no RAID, no cd-rom. But I will try again. Maybe I just did something wrong then. Thanks, Thomas signature.asc Description: PGP signature
