* [SCSI] bfa: rename log_level to bfa_log_levelJing Huang2010-12-20
| | | | | | | | | Rename log_level to bfa_log_level to make the global variable more bfa specific and avoid clashes with other drivers which was causing a build failure. Signed-off-by: Jing Huang <huangj@brocade.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
* [SCSI] bfa: fix comments for header filesJing Huang2010-10-25
| | | | | | | | | | This patch addresses the comments from Randy Dunlap (Randy.Dunlap@oracle.com) regarding comment blocks that begining with "/**". bfa driver comments currently do not follow kernel-doc convention, we hence replace all /** with /* and **/ with */.

* [SCSI] bfa: add debugfs supportJing Huang2010-07-27
| | | | | | | | | | | | | | | | | | | - Add debugfs support to obtain firmware trace, driver trace and read/write to registers. - debugfs hierarchy: /sys/kernel/debug/bfa/host# where the host number corresponds to the one under /sys/class/scsi_host/host# - Following are the new debugfs entries added: drvtrc: collect current driver trace fwtrc: collect current firmware trace. fwsave: collect last saved fw trace as a result of firmware crash. regwr: write one word to chip register regrd: read one or more words from chip register.

* [SCSI] bfa: vport fixesJing Huang2010-07-27
| | | | | | | | | | | | | | | | | This patch fixes 3 bugs in vport create/delete. 1) Replace scsi_add_host() with scsi_add_host_with_dma() 2) Fix rmmod hang when there are vports configured. This is due to a race condition between the workqueue destroy in pci remove context and the vport delete works being handled. The fix is to use a counter to track the vport delete work, so that workqueue destroy will not be called until all configured vports are deleted from workqueue. 3) Fix rmmmod crash when there are PBC vport configured. PBC is not allowed to be deleted dynamically. However, if someone try to delete it, it leaves the vport is wrong state. The fix is to restore the vport back to original state when the attempt to delete pbc vport delete is failed.

* [SCSI] bfa: PBC vport createJing Huang2010-07-27
| | | | | | | | | | | This patch enables creating PBC vport. During fcs init, fcs will read PBC vport using bfa iocfc API and invoke fcb callback to add the pbc vport entries into a list. The pbc vport list will be traversed in the subsequent pci probe process and vport will be created using fc transport provided vport create function.

| | | | | | | | | Use pci_iomap() and pci_iounmap() to simplify the code. Remove uncessary #ifdef check for ia64 (it was added as a workaound for some RHEL 5.x release which doesn't export iounmap function) Signed-off-by: Jing Huang <huangj@brocade.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

* [SCSI] bfa: Replace bfa_get_attr() with specific APIsKrishna Gudipati2010-03-07
| | | | | | | | | bfa_ioc_attr_s is a big structure and some times could cause stack overflow if defined locally, so add specific APIs that are needed to replace the use of ioc_attr local var.

* [SCSI] bfa: AEN and byte alignment fixes.Krishna Gudipati2010-03-07
| | | | | | | | | | | | | | Replace enum types with int and rearrange the fields to fix some alignment issue. Local var ioc_attr is causing the stack to overflow, so removed the usage of the local ioc_attr var and now invoking an API to return the ioc_type. Fix some AEN issues.

* [SCSI] bfa: Resume BFA operations after firmware mismatch is resolved.Krishna Gudipati2010-03-04
| | | | | | | | | | | | | | | | | | | | | | | | bfad.c & bfad_drv.h: * Created a kernel thread from pci_probe that does the bfad start operations after BFA init done on a firmware mismatch. * The kernel thread on a fw mismatch waits for an event from IOC call back and is woken up from bfa_cb_init() on BFA init success. * In normal cases of no firmware mismatch this thread is terminated in pci_probe. bfa_fcs_lport.c, fabric.c, fcs_lport.h & vport.c: * Split the lport init to attach time and init time code, so that proper config attributes are set after firmware mismatch. bfa_iocfc.c: * Handle an IOC timer issue, where the IOC timer would expire before the init completion and send Init fail event to the driver, however IOC init continues and completes successfully at the later stage. The bfa and driver were not handling this kind of deferred init completion. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
