Why did you not use board_ahci_pi? Is the AHCI ports-implemented
register unreliable on this platform?

This device has both AHCI and RAID modes that use the ahci driver. Only
the RAID mode DID's are being added as the PCI class code support will
cover the AHCI mode. Looking at the Generic, PCI class code support
section, it uses "board_ahci". I assumed that they should be the same
as the generic class code support is working on this platform.

Thanks,

Jason

Jeff,

Do I need to change this to board_ahci_pi or is it ok to leave it at
board_ahci, which will be used by the AHCI class code devices?

Thanks,

Jason

You are the one who needs to answer this question ;-)

Most new Intel AHCI have a sane and reliable Ports-Implemented register
value even across reset, unlike earlier ones or some clones. For those,
we use board_ahci_pi.

If PI is not reliable across reset or if BIOS is absent (yes we care
about that case, when we do our own PCI resume for example), then you
should use board_ahci.

At this time, I don't have any way to test those particular DeviceID's
and I know that the AHCI mode DeviceID works by using the class code
support. So, I would like to just leave them at they are, if that is
ok.

Thanks,

Jason

Fine by me... Overall I'll follow "vendor's best advice" here :)

The distinction between board_ahci and board_ahci_pi has been removed in
#upstream anyway, so it doesn't matter too much anyway.

Thanks.

applied manually, since it conflicted with Tejun's PI patch (not your fault)
