* bfs: bfad_worker cleanupJiri Slaby2015-04-171-13/+9
| | | | | | | | | | | | | This kthread is not loop at all due to break at the end of the loop. Make that function linear, with no while loop. And remove an unnecessary cast.

* bfa: Use pci_enable_msix_exact() instead of pci_enable_msix()Alexander Gordeev2014-07-291-14/+6
| | | | | | | | | | | | | As result of deprecation of MSI-X/MSI enablement functions pci_enable_msix() and pci_enable_msi_block() all drivers using these two interfaces need to be updated to use the new pci_enable_msi_range() or pci_enable_msi_exact() and pci_enable_msix_range() or pci_enable_msix_exact() interfaces.

* bfa: allocate memory with GFP_ATOMIC in spinlock contextAlexey Khoroshilov2014-05-191-1/+1
| | | | | | | | | | | | | bfa_fcb_pbc_vport_create() is called only from bfa_fcs_pbc_vport_init(), that is called only from bfad_drv_start() with bfad_lock spinlock held. So the patch replaces GFP_KERNEL with GFP_ATOMIC to avoid sleeping in atomic spinlock context. Found by Linux Driver Verification project (linuxtesting.org).

* | [SCSI] bfa: Chinook quad port 16G FC HBA claim issueVijaya Mohan Guvva2013-12-181-2/+4
|/ | | | | | | | | | | | | | | | Bfa driver crash is observed while pushing the firmware on to chinook quad port card due to uninitialized bfi_image_ct2 access which gets initialized only for CT2 ASIC based cards after request_firmware(). For quard port chinook (CT2 ASIC based), bfi_image_ct2 is not getting initialized as there is no check for chinook PCI device ID before request_firmware and instead bfi_image_cb is initialized as it is the default case for card type check. This patch includes changes to read the right firmware for quad port chinook.

Since queuing up the vport delete work at this stage will result in the FC transport layer to clean up the vport before we get the response from firmware.

* [SCSI] bfa: Implement LUN Masking feature using the SCSI Slave Callouts.Krishna Gudipati2012-01-101-0/+2
| | | | | | | | | | | | | | | | This patch re-implements LUN Masking feature using SCSI Slave Callouts. With the new design in the slave_alloc entry point; for each new LUN discovered we check with our internal LUN Masking config whether to expose or to mask this particular LUN. We return -ENXIO (No such device or address) from slave_alloc for the LUNs we don't want to be exposed. We also notify the SCSI mid-layer to do a sequential LUN scan rather than REPORT_LUNS based scan if LUN masking is enabled on our HBA port, since a -ENXIO from any LUN in REPORT_LUNS based scan translates to a scan abort. This patch also handles the dynamic lun masking config change from enable to disable or vice-versa by resetting sdev_bflags of LUN 0 appropriately.
