[SCSI] lpfc 8.3.25: Add FCF priority failover functionality

2011-07-27T11:16:05Z

This patch implements a new FCF failover policy for the lpfc driver. It allows the driver to choose which FCF to failover to based on the FCF priority. This patch also introduces a new sysfs parameter (fcf_failover_policy) to allow the user to choose which FCF failover policy to use.

[SCSI] lpfc 8.3.25: Enhancements to Debug infrastructure

2011-07-27T11:14:00Z

Enhancements to Debug infrastructure - debugfs additions for new hardware. - Correct stack overflow in lpfc_debugfs_dumpHBASlim_data() - Correct warning on uninitialized reg_val in lpfc_idiag_drbacc_write() - Separated the iDiag command for capturing mailbox commands for generic issue mailbox command entry point and for BSG multi-buffer handling. - Added capturing dumping capabiliy of mailbox command and external buffer for the completion of the mailbox command so that the outcome can be examined. - Changed all the iDiag command structure data array indexing introduced so far with properly defined macros. - Added SLI4 device PCI BAR memory mapped register read/browse, write-by- value, set-bit, and clear-bit methods for both interface type 0 and interface type 2. - Corrected warnings on mbxstatus being uninitialized in error paths in lpfc_bsg.c Signed-off-by: Alex Iannicelli Signed-off-by: James Smart Signed-off-by: James Bottomley

[SCSI] lpfc 8.3.25: PCI and SR-IOV Fixes

2011-07-27T11:12:47Z

PCI and SR-IOV Fixes - Call pci_save_state after the pci_restore_state completes. - After calling pci_enable_pcie_error_reporting() and checking the return value for logging messages from rc, reset rc to 0 to it will not later be interpreted for error. - Read PCI config space SR-IOV capability to get the number of VFs supported. - Check for the PF's supported number of VFs before invoking PCI enable sriov API call and log error message that user requested number of VFs is beyond the PF capability if such request is passed in. - Added check for Physical function with Virtual Functions attached. If so, first disable all the VFs before proceeding to device reset. Signed-off-by: Alex Iannicelli Signed-off-by: James Smart Signed-off-by: James Bottomley

[SCSI] lpfc 8.3.25: Fabric and Target Discovery Fixes

2011-07-27T11:12:19Z

Fabric and Target Discovery Fixes - Clear FC_VPORT_NEEDS_INIT_VPI flag during completion of REG_VFI mailbox command. - Prevent SLI3 Code from unregistering the physical VPI. - Add an else clause to the code that checks and sets sp->cmn.request_multiple_Nport to clear the bit. - Remove a redundant mbox free. - Modified lpfc_sli4_async_fip_evt to pass in physical VPI toi lpfc_find_vport_by_vpid function. - Modified lpfc_find_vport_by_vpid to translate physical VPI to logical VPI before comparing with vport VPI.

[SCSI] lpfc 8.3.25: Adapter Interface fixes and changes

2011-07-27T11:11:02Z

Adapter Interface fixes and changes - Modify the macro field from lpfc_init_vpi_vpi to lpfc_init_vfi_vpi - Add the new CQE_CODE_RECEIVE_V1 CQE Code, add code in the driver to handle the new Code the same as the CQE_CODE_RECEIVE code except that there are two new checks for this code that will cause the driver to use the new V1 macros for rq_id and fcf_id. - Fix a bug in lpfc_prep_seq() where the size out of the first CQE was ONLY being used, even though multiple dmabufs make up the sequence, each have their own CQE with potentially different sizes. - Fix bug in lpfc_bsg_ct_unsol_event() where the ulpContext and ulpWord[3] fields of the XMIT_SEQUENCE64_CX IOCB were being calculated incorrectly. - Do physical to logical translation before indexing into the active XRI array. - Populate physical vpi in the iocb data structure. - Put the current accumulated total in each IOCB in the chain as we are walking thru then. The last IOCB in the chain should have the total length of the sequence. Signed-off-by: Alex Iannicelli Signed-off-by: James Smart Signed-off-by: James Bottomley

[SCSI] lpfc 8.3.25: Miscellaneous Bug fixes and code cleanup

2011-07-27T11:09:14Z

Miscellaneous Bug fixes and code cleanup - Fix 16G link speed reporting by adding check for 16G check. - Change the check and enforcement of MAILBOX_EXT_SIZE (2048B) to the check and enforcement of BSG_MBOX_SIZE - sizeof(MAILBOX_t) (3840B). - Instead of waiting for a fixed amount of time after performing firmware reset, the driver shall wait for the Lancer SLIPORT_STATUS register for the readiness of the firmware for bring up. - Add logging to indicate when dynamic parameters are changed. - Add revision and date to the firmware image format. - Use revision instead of rev_name to check firmware image version. - Update temporary offset after memcopy is complete for firmware update. - Consolidated the use of the macros to get rid of duplicated register offset definitions. - Removed the unused second parameter in routine lpfc_bsg_diag_mode_enter() - Enable debugfs when debugfs is enabled. - Update function comments for lpfc_sli4_alloc_xri and lpfc_sli4_init_rpi_hdrs.

[SCSI] lpfc 8.3.25: T10 DIF Fixes

2011-07-27T11:06:29Z

T10 DIF Fixes - Fix the case where the SCSI Host supplies the CRC and driver to controller protection is on. - Only support T10 DIF type 1. LBA always goes in ref tag and app tag is not checked. - Change the format of the sense data passed up to the SCSI layer to match the Descriptor Format Sense Data found in SPC-4 sections 4.5.2.1 and 4.5.2.2. - Fix Slip PDE implementation. - Remove BUG() in else casein lpfc_sc_to_bg_opcodes.

treewide: fix potentially dangerous trailing ';' in #defined values/expressions

2011-07-21T12:10:00Z

All these are instances of #define NAME value; or #define NAME(params_opt) value; These of course fail to build when used in contexts like if(foo $OP NAME) while(bar $OP NAME) and may silently generate the wrong code in contexts such as foo = NAME + 1; /* foo = value; + 1; */ bar = NAME - 1; /* bar = value; - 1; */ baz = NAME & quux; /* baz = value; & quux; */ Reported on comp.lang.c, Message-ID: Initial analysis of the dangers provided by Keith Thompson in that thread. There are many more instances of more complicated macros having unnecessary trailing semicolons, but this pile seems to be all of the cases of simple values suffering from the problem. (Thus things that are likely to be found in one of the contexts above, more complicated ones aren't.) Signed-off-by: Phil Carmody Signed-off-by: Jiri Kosina
