lpfc 8.3.25: PCI and SR-IOV Fixes

2011-10-03T18:41:00+00:00

commit 0a96e9754d6c4a2a31e50ee6c6e36ec13f80bc25 upstream.

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.

lpfc 8.3.25: Fabric and Target Discovery Fixes

2011-10-03T18:40:59+00:00

commit 5248a7498e5f6f3d6d276080466946f82f0ea56a upstream.

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.

lpfc 8.3.25: Adapter Interface fixes and changes

2011-10-03T18:40:59+00:00

commit 7851fe2c7f294d0beccf4c3d6af52e8247b89f00 upstream.

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.

lpfc 8.3.25: Miscellaneous Bug fixes and code cleanup

2011-10-03T18:40:58+00:00

commit 88a2cfbb8bf3802ca5a90c7d1567a1e542e6ef0c upstream.

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.

lpfc 8.3.25: T10 DIF Fixes

2011-10-03T18:40:58+00:00

commit 7c56b9fd3b6d2d933075d12abee67ceb7c90d04a upstream.

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.
