2010-02-09[SCSI] mpt2sas: Added phy_enable and set_phy_speed sysfs callback support.Kashyap, Desai1-0/+2
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>

2010-02-09[SCSI] mpt2sas: User resource_size_t instead of unsigned longKashyap, Desai1-3/+1
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.

2009-10-29[SCSI] mpt2sas : Add support for RAID Action System Shutdown Initiated at OS ↵Kashyap, Desai1-0/+4
shutdown (1) Added new function _scsih_ir_shutdown. This function will issue the MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED request via MPI2_FUNCTION_RAID_ACTION. The function will wait 10 seconds for reply message frame, then print out the ioc status and loginfo. This function is only called when there are raid volumes present. (2) Add shutdown callback in the struct pci_driver object scsih_driver. This will be called only when the system is shutting down. From this function, we will call _scsih_ir_shutdown mentioned above. (3) Add support in _scsih_remove to call _scsih_ir_shutdown. The function _scsih_remove will be called when the driver is unloaded (and system is still running). scsih internal command contex is added to send internal message frames from mpt2sas_scsih.c.

2009-10-29[SCSI] mpt2sas: Added command line option diag_buffer_enable.Kashyap, Desai1-0/+3
Added command line option diag_buffer_enable. When the command line option is set, the driver will automatically post diag buffers at driver load time. The command line option diag_buffer_enable is bitwise, so it's possible to enable both and/or snapshot + trace buffers. For trace, the driver will allocate 1MB buffer, whereas for snapshot its 2MB. The purpose for this is so the enduser doesn't have to manually use an application to setup diag buffers for debugging firmware related issues. Here is some examples trace: # insmod mpt2sas.ko diag_buffer_enable=1 snapshot: # insmod mpt2sas.ko diag_buffer_enable=2 both trace and snapshot: # insmod mpt2sas.ko diag_buffer_enable=3 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>
2009-10-29[SCSI] mpt2sas: Support for stopping driver when Firmware encountersKashyap, Desai1-0/+4
Added command line option and shost sysfs attribute called mpt2sas_fwfault_debug. When enduser writes a "1" to this parameter, this will enable support in the driver for debugging firmware timeout related issues. This handling was added in three areas (a) scsi error handling callback called task_abort, (b) IOCTL interface, and (c) other timeouts that result in diag resets, such as manufacturing config pages. When this support is enabled, the driver will provide dump_stack to console, halt controller firmware, and panic driver. The end user probably would want to setup serial console redirection so the dump stack can be seen. Here are the three methods for enable this support: (a) # insmod mpt2sas.ko mpt2sas_fwfault_debug=1 (b) # echo 1 > /sys/module/mpt2sas/parameters/mpt2sas_fwfault_debug (c) # echo 1 > /sys/class/scsi_host/host#/fwfault_debug (where # is the host number) 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>
2009-10-29[SCSI] mpt2sas: Driver will use sas address instead of handle as a lookupKashyap, Desai1-12/+8
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>

2009-10-02[SCSI] mpt2sas: Target Reset will be issued from Interrupt context.Kashyap, Desai1-11/+30
(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.

2009-10-02[SCSI] mpt2sas: Added SCSIIO, Internal and high priority memory pools to ↵Kashyap, Desai1-4/+45
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.

2009-09-05[SCSI] mpt2sas: Raid 10 Volume is showing as Raid 1E in dmesgKashyap, Desai1-1/+36
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.

Following host reset its possible that the controller firmware could assign new handles for devices, as well as adding or deleting devices. There is code in the driver that will rescan the topology folowing host reset; updating device handles, and remove devices that are no longer responding.
