I haven't bothered changing the chip setup stuff from PCI config cycles to MMIO though (siimage does it), I don't think it matters, I've only adapted it to use MMIO for taskfile accesses. I've tested it on a Cell blade and it seems to work fine.

Use only register transfer timing for both data and register transfers. This gives poorer performance in PIO1 and 2, but should not be a problem in PIO3 and 4, correct me if I'm wrong :) The driver works very we'll but I still wonder about the interrupts. I have an interrupt line, that works nicely when POLLING flag is not set. The problem is the number of interrupts that eat away my CPU cycles. When using the POLLING flag there seem to be some interrupts that dosen't get cleared. Furthermore the device dosen't drive INTRQ high, it stays at 2.5 volts and generates a lot of interrupts due to ripple / noise. What to do?

For example, this happens when probing IDENTIFY fails because of a phantom device. In these cases, all the repeated EH does is making sure there is no unhandled error or pending action and return. This repeation is necessary to avoid losing any event which occurred while EH was in progress. Unfortunately, this dry run causes annonying "EH pending after completion" message. This patch moves the repeat reporting into ata_eh_report() such that it's more compact and skipped on dry runs.

This patch implements and uses ata_port_desc() and ata_port_pbar_desc(). ata_port_desc() is almost identical to ata_ehi_push_desc() except that it takes @ap instead of @ehi, has no locking requirement, can only be used during host initialization and " " is used as separator instead of ", ". ata_port_pbar_desc() is a helper to ease reporting of a PCI BAR or an offsetted address into it. LLD pushes whatever description it wants using the above two functions. The accumulated description is printed on host registration after "[S/P]ATA max MAX_XFERMODE ". SFF init helpers and ata_host_activate() automatically add descriptions for addresses and irq respectively, so only LLDs which isn't standard SFF need to add custom descriptions. In many cases, such controllers need to report different things anyway.

Intel has never officially supported anything faster than PATA 100MB/s. But, the ata_piix.c driver "define" the ICH5 & ICH7 as UDMA6 (aka 133MB/s) capable. [ Well, no one has probably noticed it before, because there is bug in do_pata_set_dmamode... Just look at libata_atapiix_enable_real_udma133.patch and you'll see what wrong with it. ] Here are Intel's datasheets for the affected chipsets: ICH5 Datasheet: http://www.intel.com/design/chipsets/datashts/252516.htm (See note on page 183: "... the ICH5 supports reads at the maximum rate of 100MB/s.") ICH7 Datasheet: http://www.intel.com/design/chipsets/datashts/307013.htm (See first note on page 190: "... the ICH7 supports reads at the maximum rate of 100MB/s.") They are two different ways to deal with it: - Either - 1. replace all ich_pata_133 with ich_pata_100. (libata_atapiix_disable_udma6.diff - diff from 2.6.22 ) - Or - 2. keep all ich_pata_133 and fix the bug in "do_pata_set_dmamode".

They just repeat the same operation over all configured links. The only change to ata_eh_revalidate_and_attach() is avoiding calling ->cable_select() on non-host ports. ata_eh_recover() update is more complex as it first processes all resets and then performs the rest. This is necessary as thawing with some links in unknown state can be dangerous. ehi->action is cleared on successful recovery of a link to avoid repeating recovery due to failures in other links. ata_eh_recover() iterates over only PMP links if PMP is attached, and, on failure, the failing link is returned in @failed_link instead of disabling devices directly. These are to integrate ata_eh_recover() into PMP EH later.

Promise's partial- source FT TX4200 driver confirms this classification. Treating it as a first-generation chip causes several problems: 1. Detection failures. This is a recent regression triggered by the hotplug-enabling changes in 2.6.23-rc1. 2. Various "failed to resume link for reset" warnings. This patch fixes . Thanks to Stephen Ziemba for reporting the bug and for testing the fix.
