Subject: [PATCH] 2.6.1-rc2 - MPT Fusion driver 3.00.00 update

Here's an driver update for mpt fusion driver version 3.00.00.

If you find this inline patch malformed,
please kindly download this patch from this URL:

ftp://ftp.lsil.com/HostAdapterDrivers/linux/Fusion-MPT/2.6-patches/

3.00.00 changes
* added new PCI API support
* added ACPI support
* added CONFIG_LBA, READ16, WRITE16 support
* underun fix
* chain buffer free list not being init properly
* reduce task management
(abort=2sec,reset bus=5sec, timeout=10sec)

Eric, since this is for 2.6.x, need the driver export anything in
/proc anymore, preferring to export via sysfs instead?

Thanks,

this looks really really wrong. Linux suspend and resume are absolutely
not acpi specific and drivers should not use ACPI specific defines that
also just may mean something different than the linux API means!

I would suggest making mpt_dv_deregister() and co a nop in the DISABLE
case, that way you don't need ifdefs all over the driver but just around
the entire functions....

This is all pretty verbose. The normal style for device drivers is:

static struct pci_device_id mptbase_pci_table[] = {
{ PCI_VENDOR_ID_LSI_LOGIC, PCI_DEVICE_ID_LSI_FC909,
PCI_ANY_ID, PCI_ANY_ID, 0, 0, DEVT_INDEX_MPT },
{ PCI_VENDOR_ID_LSI_LOGIC, PCI_DEVICE_ID_LSI_FC929,
PCI_ANY_ID, PCI_ANY_ID, 0, 0, DEVT_INDEX_MPT },
{ PCI_VENDOR_ID_LSI_LOGIC, PCI_DEVICE_ID_LSI_FC919,
PCI_ANY_ID, PCI_ANY_ID, 0, 0, DEVT_INDEX_MPT },
{ PCI_VENDOR_ID_LSI_LOGIC, PCI_DEVICE_ID_LSI_FC929X,
PCI_ANY_ID, PCI_ANY_ID, 0, 0, DEVT_INDEX_MPT },
{ PCI_VENDOR_ID_LSI_LOGIC, PCI_DEVICE_ID_LSI_FC919X,
PCI_ANY_ID, PCI_ANY_ID, 0, 0, DEVT_INDEX_MPT },
{ PCI_VENDOR_ID_LSI_LOGIC, PCI_DEVICE_ID_LSI_53C1030,
PCI_ANY_ID, PCI_ANY_ID, 0, 0, DEVT_INDEX_MPT },
{ PCI_VENDOR_ID_LSI_LOGIC, PCI_DEVICE_ID_LSI_53C1035,
PCI_ANY_ID, PCI_ANY_ID, 0, 0, DEVT_INDEX_MPT },
{ }
}

Although since you don't make any use of DEVT_INDEX_MPT, you can drop the last
three entries and simply write:

{ PCI_VENDOR_ID_LSI_LOGIC, PCI_DEVICE_ID_LSI_53C1035,
PCI_ANY_ID, PCI_ANY_ID },
