* [SCSI] mpt2sas: Do not call sas_is_tlr_enabled for RAID volumes.Kashyap, Desai2010-02-171-3/+5
| | | | | | | | | | For RAID volume sas_is_tlr_enabled call will hit BUG at scsi_transport_sas.c:163, since raid volume is not visible to sas transport layer. Now Added check to make sure arg pass in sas_is_tlr_enabled() is not a volume. Signed-off-by: Kashyap Desai <kashyap.desai@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

* [SCSI] mpt2sas: Added phy_enable and set_phy_speed sysfs callback support.Kashyap, Desai2010-02-083-17/+232
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Kashyap Desai <kashyap.desai@lsi.com> Reviewed-by: Eric Moore <eric.moore@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

| | | | | | | | | | | | | | 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.

Due to a sanity check in the driver, the devices there were not added, were never handshaked to firmware with the device removal handshake protocal. Since the driver didnt' do the handshake, the controller never provide further add events.

|/ | | | | | | | | | | | | | | | | The device driver was not handling updating device handles in all cases across diag resets. To fix this issue, the driver is converted to using sas address instead of handle as a lookup reference to the parent expander or sas_host. Also, for both expanders and sas host, the phy handle will be one unique handle. In the sas host case, the phy handle can be different for every phy, so the change is to set the handle to the handle of the first phy; every phy will be one single sas address(phy 0) instead of a different sas address for every phy(previous implementation). So making one consistent sas address for all the direct attachedports to the sas host, will make it better user experience when using udev /dev/disk/by-path dev nodes Signed-off-by: Kashyap Desai <kashyap.desai@lsi.com> Signed-off-by: Eric Moore <Eric.moore@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

| | | | | | | | | | | | | | | | firmware to ACK. Following a diag_reset, a request to send an ioc_init is timing out. The timeout occurred within the HANDSHAKE logic while waiting on firmware to acknowledge that the driver had wrote to the doorbell register. This was root caused to a logic timeout in the firmware code. The proposed solution is for the driver to call the udelay instead of msleep API in function where its looping reading the interrupt status. In addition to this change, there were two additional cases where we deleted the clearing interrupt status outside handshake context.

* [SCSI] mpt2sas: Call init_completion on a per request basis.Kashyap, Desai2009-10-023-3/+10
| | | | | | | | | | | | Now driver call init_completion on a per request basis. At some point the wait_for_completion_timeout is not waiting for the timeout, instead returning immediately, thus going into diag reset. This fix will address all request using the wait_for_completion_timeout API. The previous implimentation was only calling init_completion at driver load time.

* [SCSI] mpt2sas: Target Reset will be issued from Interrupt context.Kashyap, Desai2009-10-026-54/+372
| | | | | | | | | | | | | | | | | | (1) Added three new functions to handle sending target resest and OP_REMOVE from interrupt time, they are _scsih_tm_tr_send, _scsih_tm_tr_complete, and _scsih_sas_control_complete. This code will create a link list of pending target resets if there is no more available request in the hipriority request queue. The list is stored in ioc->delayed_tr_list. (2) All callback handler return type is changed from void to u8. Now _base_interrupt will check for return type of callback handlers to take decision of message frame is already freed or not. In genral, Return 1 meaning mf should be freed from _base_interrupt 0 means the mf is freed from function.

* [SCSI] mpt2sas: Added SCSIIO, Internal and high priority memory pools to ↵Kashyap, Desai2009-10-024-137/+307
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | support multiple TM 1) create a pool of high priority message frames in the region of memory between message frames and chains. The modifications are in _base_allocate_memory_pools. Also create a seperate pool of memory for internal commands located near the same region of memory. The pool of high priority message frames is restriced by the facts->HighPriorityCredit. 2) Create additional API for accessing request message frames. New function mpt2sas_base_get_smid_hpr is for highpriority request. New function mpt2sas_base_get_smid_scsiio for SCSI_IO, passing in the scsi command pointer. The mpt2sas_base_get_smid function is for requesting internal commands. 3) Added new function _base_get_cb_idx to obtain the callback index from one of the three pools of request message frames. 4) Removed wrapper functions _scsih_scsi_lookup_set and _scsih_scsi_lookup_getclear. These were removed because this handling was moved into mpt2sas_base_get_smid_scsiio and mpt2sas_base_free_smid. 5) The function mpt2sas_base_free_smid is modified so the request message frames are put back on one of the three pools of request message frames.

| | | | | | | | | | | | | | | This patch modifies the slave_configure callback so the messages that get sent to system log for RAID1E volumes contain the string "RAID10" instead of "RAID1E". These messages contain information regarding what kind of scsi device is being added. Certain OEMS can enable displaying the RAID10 string instead of RAID1E via manufacturing page 10. The driver will read this config page at driver load time, then determine from the GenericFlags0 bits whether display the RAID10 or RAID1E string, also even drive count is taken into consideration.

| | | | | | | | | | | | | | | This patch renames the flag for indicating host reset from ioc_reset_in_progress to shost_recovery. It also removes the spin locks surrounding the setting of this flag, which are unnecessary. Sanity checks on the shost_recovery flag were added thru out the code so as to prevent sending firmware commands during host reset. Also, the setting of the shost state to SHOST_RECOVERY was removed to prevent deadlocks, this is actually better handled by the shost_recovery flag.
