Hello All,
I have a Core 2 Duo & Intel 3100 chipset SBC. Of the six ports
supported by the SATA controller ,three have been routed to SST based
512MB NAND flashes which provide ATA/IDE compatible interface.One of
the three NAND flash is on AHCI only port so to access it I need to
enable the AHCI support in the BIOS. The kernel version I am using is
2.6.23 .
When I am running in the IDE mode, I am able to access the two
NAND devices without any issues but when I enable the AHCI mode to
access the third flash , the access to all the NAND devices fail. I
have attached the dumps with the debug flags enabled below.
Should I be able to do this in the first place as my NAND devices
as stated provide only ATA/IDE emulation ? I disabled the NCQ in the
AHCI driver but saw the same result. I would appreciate any pointers
on the same,
Regards,
Girish

libata.dma=1 should do the trick for 2.6.24-rcX. For 2.6.23, there
isn't any. :-(

I sent Jeff a patch a while back to allow libata DMA to be enabled
seperately for disk, atapi and CF. So yes.

For CF specifying libata.dma=3 should do the trick even better as it will
leave DMA enabled on disk and ATAPI

Hello All,
Thanks for your replies. If we see the dump, you will observe that
the NAND flash supports the MDMA2 but the driver does not set it but
goes in for PIO4. On looking at the ata_port_info structure populated
in case of 3100 SATA controller chipset namely the first entry, the
mwdma mask is not initialized causing the driver to skip the same and
go in for PIO modes. When I did add the MDMA mask, everything fell in
place and I was able to access the flash devices.
Can you please let me know if there is any specific reason as to
why the mdma masks are not added in the ata_port_info initialisations.
Regards,
Girish

We are talking about AHCI, right?
Just an oversight IIRC. ISTR the original logic was somewhat of a
guess, since ahci.c was originally written in the early SATA days -- and
also admittedly when I understood less about SATA. I was worried about
controller snooping, and also did not think it would be needed to
support MWDMA, when UDMA was supported.
Obviously those were flawed trains of thought, in hindsight.
Jeff
