My working tree now successfully probes and attaches all devices over the PM and I'm currently trying to get EH and hotplug to work with it nicely. EH/hotplug are being changed to support PM. Effects on LLDDs are minimal but you can probably save some work by waiting for the next round of patches before porting to new EH. I think/hope this can be finished in this week and bombard Jeff with patches (updated EH, NCQ, hotplug and PM) before the weekend, so that Jeff can have some time to review and hopefully merge some of it into #upstream before he goes off on honeymoon. In some convoluted way, the patches will be my marriage gift, heh heh. Jeff, *BIG* congratulations. I wish you a great marriage.

As you see, once the EH hurdle is cleared, it is much easier to add new features. New features will start flooding in, from you and others. BTW don't forget we want to push Albert's irq-pio branch into upstream sometime soon after your EH work settles. I would put irq-pio in front of NCQ and PM, particularly.

I would put irq-pio in front > of NCQ and PM, particularly. Hmmm... EH, NCQ, PM stuff doesn't really interfere with irq-pio. The only thing which needs special attention is hotplug support for sata_sil as the driver requires PIO HSM implementation but needs to use its own interrupt handler. So, we need to separate out PIO HSM from ata_host_intr() and allow LLDD irq handlers to drive it. Albert, what do you think? -- tejun ^ permalink raw reply [flat|nested] 4+ messages in thread

In the irq-pio branch, the HSM code has been seperated out from ata_host_intr() to ata_hsm_move() as static function currently. Maybe we can export ata_hsm_move() as external? I didn't look into how sil3611 hotplug interacts with PIO HSM. Don't know whether this is good enough for the need of sata_sil. -- albert ^ permalink raw reply [flat|nested] 4+ messages in thread
