| | * libata: kill spurious NCQ completion detectionTejun Heo2007-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Spurious NCQ completion detection implemented in ahci was incorrect. On AHCI receving and processing FISes and raising interrupts are not interlocked and spurious interrupts are expected. For example, if an interrupt occurs while interrupt handler is running and the running interrupt handler handles the event the new IRQ indicated, after IRQ handler finishes, it will be executed again because IRQ pending bit is set by the new interrupt but there won't be anything to process. Please read the following message for more information. http://article.gmane.org/gmane.linux.ide/26012 This patch... * Removes all spurious IRQ whining from ahci. Spurious NCQ completion detection was completely wrong. Spurious D2H Register FIS taught us that some early drives send spurious D2H Register FIS with I bit set while NCQ commands are in progress but none of recent drives does that and even the ones which show such behavior can do NCQ fine. * Kills all NCQ blacklist entries which were added because of spurious NCQ completions. I tracked down each commit and verified all removed ones are actually added because of spurious completions. WD740ADFD-00NLR1 wasn't deleted but moved upward because the drive not only had spurious NCQ completions but also is slow on sequential data transfers if NCQ is enabled. Maxtor 7V300F0 was added by 0e3dbc01d53940fe10e5a5cfec15ede3e929c918 from Alan Cox. I can only find evidences that the drive only had troubles with spuruious completions by searching the mailing list. This entry needs to be verified and removed if it doesn't have other NCQ related problems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ICH6 R/Ms share PCI ID between piix and ahci modes and we've been allowing ahci to attach regardless of how BIOS configured it. However, enabling AHCI mode when the controller is in combined mode can result in unexpected behavior. Don't attach if the controller is in combined mode.

| * | ibm_newemac: Workaround reset timeout when no linkBenjamin Herrenschmidt2007-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With some PHYs, when the link goes away, the EMAC reset fails due to the loss of the RX clock I believe. The old EMAC driver worked around that using some internal chip-specific clock force bits that are different on various 44x implementations. This is an attempt at doing it differently, by avoiding the reset when there is no link, but forcing loopback mode instead. It seems to work on my Taishan 440GX based board so far.
