[SCSI] lpfc 8.3.28: Critical Miscellaneous fixes

2011-12-15T06:57:45+00:00

- Make lpfc_sli4_pci_mem_unset interface type aware (CR 124390)
- Convert byte count to word count when calling __iowrite32_copy (CR 122550)
- Checked the ERR1 and ERR2 registers for error attention due to SLI
  Port state affected by forced debug dump. (CR 122986, 122426, 124859)
- Use the lpfc_readl routine instead of the readl for the port status
  register read in lpfc_handle_eratt_s4 (CR 125403)
- Call lpfc_sli4_queue_destroy inside of lpfc_sli4_brdreset before doing
  a pci function reset (CR 125124, 125168, 125572, 125622)
- Zero out the HBQ when it is allocated (CR 125663)
- Alter port reset log messages to indicate error type (CR 125989)
- Added proper NULL pointer checking to all the places that accessing
  the queue memory (CR 125832)

scsi: Fix up files implicitly depending on module.h inclusion

2011-10-31T23:31:24+00:00

The module.h header was implicitly present everywhere, so files
with no explicit include of the module infrastructure would build
anyway.  We are now removing the implicit include, and so we need
to call out the module.h file that we need explicitly.

[SCSI] lpfc 8.3.25: Enhancements to Debug infrastructure

2011-07-27T11:14:00+00:00

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

[SCSI] lpfc: Silence DEBUG_STRICT_USER_COPY_CHECKS=y warning

2011-06-29T15:40:35+00:00

Enabling DEBUG_STRICT_USER_COPY_CHECKS causes the following
warning:

In file included from arch/x86/include/asm/uaccess.h:573,
                 from include/linux/uaccess.h:5,

arch/x86/include/asm/uaccess_64.h:65:
warning: call to 'copy_from_user_overflow' declared with

correct

presumably due to buf_size being signed causing GCC to fail to
see that buf_size can't become negative.

[SCSI] lpfc 8.3.24: Miscellaneous Fixes and Corrections

2011-05-27T03:49:35+00:00

Miscellaneous Fixes and Corrections
- Remove the memset in the lpfc_sli4_remove_rpi_hdrs call.
- Correct swapping of SGE word 2 relative to offset value
- Reorganize CQ and EQ usage to comply with SLI4 Specification.
- Expand the driver to check the rn bit. Only detect an error if the error bit
  is set and the RN bit is NOT set.
- If mailbox completion code is not success AND the mailbox status is success,
  then and only then will the driver overwrite the mailbox status.
- When driver initializing device, if the device is on a PCIe bus, set
  PCI's "needs fundamental reset" bit so that EEH uses fundamental reset
  instead of hot reset for recovery.
- Prevent driver from using new WWN when changed in firmware (until driver
  reload)
- When HBA reports maximum SGE size > 0xffffffff (infinite), override
  with 0x80000000.
- Fixed potential missed SLI4 device initialization failure conditions.
- Added 100ms delay before driver action following IF_TYPE_2 function reset.
- Reverted patch to UNREG/REG on PLOGI to mapped/unmapped node.
- Add a check for the CVL received flag in the fcf inuse routine to avoid
  unregistering the fcf if Devloss fires before Delay discover timer fires.
