pvscsi_setup_msix() expects 'irq' argument to be an int but is being passed unsigned int. Unsigned int is more proper type for IRQ number so let's use it. This shuts off a compile warning with recent compilers. Signed-off-by:

This fix allows the driver to load when the FW allows more cids than than the driver supports. The driver will limit the number of cid to what it can support. There was no reason to fail the driver load,so, correcting that Signed-off-by:

If TLR is supported for end device, MPT2SAS driver will enable the TLR bit in the SCSI_IO for every request. If there is a response with MPI2_SCSITASKMGMT_RSP_INVALID_FRAME, the driver will turn off the TLR logic. [jejb: updated to new transport class TLR API] Signed-off-by:

Added new callbacks phy_enable and set_phy_speed in the mpt2sas_transport_functions template. This will allow end user to enable/disable phys and change links rates using the SysFS interface. Current implementation only supports direct attached phys, but we could in the future add support for expander based phys. A new subroutine mpt2sas_config_set_sas_iounit_pg1 was added; this wrapper function used to send request to controller firmware to modify the phys and link rates. A new subroutine _transport_find_local_phy was added; a function for easly obtaining the local phy object for direct attached. Example to disable a phy echo 0 > /sys/class/phy3:0/enable Example to enable the same phy echo 1 > /sys/class/phy3:0/enable Example to change the link rate to 1.5 #echo "1.5 Gbit" > /sys/class/phy3:0/maximum_linkrate #cat /sys/class/phy3:0/negotiated_linkrate 1.5 Gbit Example to change the link rate to 3.0 #echo "3.0 Gbit" > /sys/class/phy3:0/maximum_linkrate #cat /sys/class/phy3:0/negotiated_linkrate 3.0 Gbit Example to change the link rate to 6.0 #echo "6.0 Gbit" > /sys/class/phy3:0/maximum_linkrate #cat /sys/class/phy3:0/negotiated_linkrate 6.0 Gbit Signed-off-by:

On ppc64, an 32bit application was failing due to data buffers not being copied properly from user to kernel memory. The problem due to improper conversion of 32 to 64 bit pointers. The fix is to use compat_ptr to setup the pointer compatibility in the routine _ctl_compat_mpt_command. Signed-off-by:

Use resource_size_t to define the type resource for the system interface register set. The existing implementation was using "unsigned long" which would be 32 bit in 32 bit OS. If 32 bit OS is using 64 bit physical address space for the system interface register set, we need to shift to using resource_size_t which takes care of physical address space. Signed-off-by:

The driver hangs when doing `rmmod mpt2sas` if there are any IR volumes present.The hang is due the scsi midlayer trying to access the IR volumes after the driver releases controller resources. Perhaps when scsi_remove_host is called,the scsi mid layer is sending some request. This doesn't occur for bare drives becuase the driver is already reporting those drives deleted prior to calling mpt2sas_base_detach. To solve this issue, we need to delete the volumes as well.

The mpt2sas driver wants to use transport layer retries (TLR) so the simplest thing to do seems to be to add the enabling flags and checks to the SAS transport class, since they're a SAS specific protocol feature. Signed-off-by:

A Gentoo bug report [1] showed that as of 2.6.31 lpfc only uses INTx interrupts. This patch restores lpfc's ability to support MSI-X/MSI interrupts that the "Addition of SLI4 Interface - Base Support" patch [2] broke. It reestablishes MSI-X as the default interrupt method and in case MSI-X is not supported lpfc_sli{4,}_enable_intr fallbacks to MSI and then to INTx. [1]: http://bugs.gentoo.org/show_bug.cgi?id=296319 [2]: commit da0436e9 [James Smart: Background: Nothing Broke. This was intended. We had originally enabled MSI-X by default, but in qualification within the last 12 months, we encountered a major catch-22: There were at least 4 platforms, from 2 major OEMs, that : - Say they support MSI-X - platform routines work and act as if they do. - We enable it, generate a test interrupt to check they really do deliver it, and it works. - But shortly after attachment, the system hangs or loses interrupts, resulting in a bad system behavior. Given the distro's picking up the 2.6.32 kernel, we had to stick with a default of MSI-X off, with user-enabled MSI-X as these platforms couldn't get fixed. However, we're also now encountering platforms that require MSI-X and never INTx, so we must change. It's desired also for also for performance reasons. So - now (2.6.33) is the right time to re-enable MSI-X by default. ] [jejb: fix up comment on default values] Signed-off-by:George Kadianakis <desnacked@gmail.com> Acked-by:

Further to the lsml thread titled: "does scsi_io_completion need to dump sense data for ata pass through (ck_cond = 1) ?" This is a patch to skip logging when the sense data is associated with a SENSE_KEY of "RECOVERED_ERROR" and the additional sense code is "ATA PASS-THROUGH INFORMATION AVAILABLE". This only occurs with the SAT ATA PASS-THROUGH commands when CK_COND=1 (in the cdb). It indicates that the sense data contains ATA registers. Smartmontools uses such commands on ATA disks connected via SAT. Periodic checks such as those done by smartd cause nuisance entries into logs that are: - neither errors nor warnings - pointless unless the cdb that caused them are also logged Signed-off-by:Douglas Gilbert <dgilbert@interlog.com> Signed-off-by:
