* ahci: change 'masking port_map' printk to KERN_WARNING levelLinus Torvalds2011-06-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's not so much an error as a warning about normal Marvell crazines. So don't use KERN_ERR that ends up spamming the console even in quiet mode, it's not _that_ critical. Explained by Jeff: "Long explanation, it's a mess: Marvell took standard AHCI, and bastardized it to include a weird mode whereby PATA devices appear inside the AHCI DMA and interrupt infrastructure you're familiar with. So, PATA devices appear via pata_marvell driver, using basic legacy IDE programming interface. But SATA devices, which might also be attached to this chip, either work in under-performing mode or simply don't work at all (e.g. newer 6 Gbps devices or port multiplier attachments, NCQ, ...) On the other hand, 'ahci' driver loads and works with the chip's attached SATA devices quite beautifully, but is completely unable to drive any attached PATA devices, due to the Marvell-specific PATA-under-AHCI interface. The "masking port_map 0x7 -> 0x3" message is the ahci driver "hiding" the PATA port(s) from itself, making sure it will only drive the SATA ports it knows how to drive."

* pata_marvell: Add support for 88SE91A0, 88SE91A4Paweł Drewniak2011-06-24
| | | | | | | | | | | This patch enables support for Marvell IDE PATA controllers found on Asus P8P67LE motherboard. The formatting has been corrected and I also received a report from two users of this motherboard that the patch works.

* libata: fix unexpectedly frozen port after ata_eh_reset()Tejun Heo2011-06-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To work around controllers which can't properly plug events while reset, ata_eh_reset() clears error states and ATA_PFLAG_EH_PENDING after reset but before RESET is marked done. As reset is the final recovery action and full verification of devices including onlineness and classfication match is done afterwards, this shouldn't lead to lost devices or missed hotplug events. Unfortunately, it forgot to thaw the port when clearing EH_PENDING, so if the condition happens after resetting an empty port, the port could be left frozen and EH will end without thawing it, making the port unresponsive to further hotplug events. Thaw if the port is frozen after clearing EH_PENDING. This problem is reported by Bruce Stenning in the following thread. http://thread.gmane.org/gmane.linux.kernel/1123265 stable: I think we should weather this patch a bit longer in -rcX before sending it to -stable. Please wait at least a month after this patch makes upstream. Thanks. -v2: Fixed spelling in the comment per Dave Howorth.

Fix this by porting the CNTRL register port detection logic from IDE cmd64x. In addition, following converns from Alan Cox, add a check to see if a mobility electronics bridge is the immediate parent and forgo the check if it is (prevents problems on hotplug controllers).

An openSUSE user reported a similar issue with his DVR-216D that the NOSETXFER horkage worked around for him as well. This patch adds the DVR-216D (1.08) to the horkage list for NOSETXFER.

* | ahci: don't enable port irq before handler is registeredMaxime Bizon2011-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ahci_pmp_attach() & ahci_pmp_detach() unmask port irqs, but they are also called during port initialization, before ahci host irq handler is registered. On ce4100 platform, this sometimes triggers "irq 4: nobody cared" message when loading driver. Fixed this by not touching the register if the port is in frozen state, and mark all uninitialized port as frozen.

There is a one to one mapping between register bit and devices on Port multiplier(PMP) i.e. bit 0 represents PMP device 0 and bit 1 represents PMP device 1 etc. Current implementation treats Device error register value as device number not set of bits representing multiple device on PMP. It is changed to consider bit level. No need to check for each set bit as all command is going to be aborted.
