SiI3112 DMA? (2.6.0-test6)

SiI3112 DMA? (2.6.0-test6)

[Jurgen Kramer]

Hi,

I am currently running 2.6.0-test6 on an old PII which has a SiI3112
SATA PCI card in one of its PCI slots. It seems that the SiI3112 is not
using DMA so now it is even running slower then the onboard PIIX4 IDE
controller.

Is DMA supported on the Si3112? DMA is not being enabled by the SiI3112
card's BIOS (this is a cheap PCI card):

SiI3112 Serial ATA: IDE controller at PCI slot 0000:00:0b.0

   I get this, too, on 2.4.22-ac2, and I've had someone else tell me
about the same issue with their card (don't know what kernel he's
running).

   This is on the SIIG 2-channel PCI card (SA-SIG212). If I copy
anything large (a couple of hundred megabytes of data) to the disk,
then the data rate to the disk drops slowly (on what appears to be an
exponential decay), and then drops to zero for about 7-10 seconds,
followed by a complete system lock-up for 1-2 seconds when the
transfer rate goes through the roof, followed by another 7-10 seconds
of no transfer and another lock-up, and so on. (I'm using gkrellm to
get this data throughput information).

   Filesystem is ReiserFS, FWIW. More details below.

Same problems here. My kernel version is 2.4.22, but more important is 
that the driver version is 1.06. My card is manufactured by "VScom" and 
it looks almost identical compared to the evaluation card made my 
Silicon Image.

I'm having the same problems and I'm using the ol' 2.4.20-20.9 kernel 
with RH 9. I had to give up on my Serial to IDE convertor so now I'm 
using IDE again (I couldn't stand the 1.3 MB/sec transfer rate with the 
SiI3112 so I reinstalled using IDE). Anyway, I too am looking for a fix 
for this but it looks to me like very little if anything has changed 
since 2.4.x. My system also crashes (to say the least! I lose all access 
to my HD) when I try hdparm -X66 -d1 /dev/hdg.

Re: SiI3112 DMA? (2.6.0-test6)

[Andre Hedrick]

I have a scheduled fix prepared for release and review by SiI monday
morning 9AM Pacific time.  Once it is cleared by SiI, it will be released
out to the masses.

I can only chortle over the issue of how attempts to replace me, and me
trying to escape the indenture servant slave of maintainership yet still
bound after nearly 6 years.

Will attempt to address the mod15b phy issues

Cheers,

   That's good news. Thank you.

   mod15b phy? Me simple idiot. Me no understand. :)

   Is that the PATA/SATA converter that the last poster mentioned? Or
something else?

Re: SiI3112 DMA? (2.6.0-test6)

[Andre Hedrick]

It is an issue with first generation FIS transfer on the wire.

Take the size of the request in sectors and divide by 15 or 7.5K.
Standard FIS packet size is 8K.

Without going into much detail because of NDA's, there needs to be a
special DMA engine build table.

I did it once then lost the code because of lack of sleep.

So SiImage is cooperating with you on getting the SATA driver right? I've
been holding out on updating the kernel (I could probably extract the 
driver
diffs, but whatever) since experiencing data corruption/lockups on my 
SiImage
controller. If we can expect reliable, fast performance with this
controller soon, thats great news : )

Is this fix going to go directly into the kernel or is it going to be 
released as some kind of a patch?
