RX_WATER_MARK sets the number of locations in Rx FIFO that can be used before the transport layer instructs the link layer to transmit HOLDS. Note that it can take some time for the HOLDs to get to the other end, and that in the interim there must be enough room in the FIFO to absorb all data that could arrive. Update the new recommended value to 16. Signed-off-by:

When a single device error is detected, the device under the error is indicated by the error bit set in the DER. 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. Signed-off-by:

Some DMA controllers (eg: drivers/dma/dw_dmac*) allow platform specific configuration for dma transfers. User drivers need to set chan->private field of channel with pointer to configuration data. This patch takes dma_priv data from platform data and passes it to chan->private_data, in order to pass platform specific configuration to DMAC controller. Signed-off-by:

The conversion is quite complex given that the libata new error handler has to be hooked into the current libsas timeout and error handling. The way this is done is to process all the failed commands via libsas first, but if they have no underlying sas task (and they're on a sata device) assume they are destined for the libata error handler and send them accordingly. Finally, activate the port recovery of the libata error handler for each port known to the host. This is somewhat suboptimal, since that port may not need recovering, but given the current architecture of the libata error handler, it's the only way; and the spurious activation is harmless.

Right at the moment, the libata error handler is incredibly monolithic. This makes it impossible to use from composite drivers like libsas and ipr which have to handle error themselves in the first instance. The essence of the change is to split the monolithic error handler into two components: one which handles a queue of ata commands for processing and the other which handles the back end of readying a port. This allows the upper error handler fine grained control in calling libsas functions (and making sure they only get called for ATA commands whose lower errors have been fixed up). Signed-off-by:

The SCSI host eh_cmd_q should be protected by the host lock (not the port lock). This probably doesn't matter that much at the moment, since we try to serialise the add and eh pieces, but it might matter in future for more convenient error handling. Plus this switches libata to the standard eh pattern where you lock, remove from the cmd queue to a local list and unlock and then operate on the local list. Signed-off-by:

For historical reasons, libsas uses the scsi host lock as the ata port lock, and libata always uses the ata host. For the old eh, this was largely irrelevant since the two locks were never mixed inside the code. However, the new eh has a case where it nests acquisition of the host lock inside the port lock (this does look rather deadlock prone). Obviously this would be an instant deadlock if the port lock were the host lock, so switch the libsas paths to use the ata host lock as well. Signed-off-by:

The function ata_sas_port_init() has always really done its own thing. However, as a precursor to moving to the libata new eh, it has to be properly using the standard libata scan paths. This means separating the current libata scan paths into pieces which can be shared with libsas and pieces which cant (really just the async call and the host scan). Signed-off-by:

ata_eh_analyze_serror() suppresses hotplug notifications if LPM is being used because LPM generates spurious hotplug events. It compared whether link->lpm_policy was different from ATA_LPM_MAX_POWER to determine whether LPM is enabled; however, this is incorrect as for drivers which don't implement LPM, lpm_policy is always ATA_LPM_UNKNOWN. This disabled hotplug detection for all drivers which don't implement LPM. Fix it by comparing whether lpm_policy is greater than ATA_LPM_MAX_POWER. Signed-off-by:

Several ACPI drivers fail to build if CONFIG_NET is unset, because they refer to things depending on CONFIG_THERMAL that in turn depends on CONFIG_NET. However, CONFIG_THERMAL doesn't really need to depend on CONFIG_NET, because the only part of it requiring CONFIG_NET is the netlink interface in thermal_sys.c. Put the netlink interface in thermal_sys.c under #ifdef CONFIG_NET and remove the dependency of CONFIG_THERMAL on CONFIG_NET from drivers/thermal/Kconfig. Signed-off-by:
