* [SCSI] qla2xxx: Correct rport/fcport visibility-state handling during ↵Seokmann Ju2008-07-263-4/+8
| | | | | | | | | | | | | | | | loop-resync. There were several issues here, one, during RSCN handling if a follow-on RSCN occurred (within interrupt context) the DPC thread could inadvertantly leave the fcport in a stale lost state. Secondly, scheduled rport removal is handled exclusively by the 'parent' DPC thread, so wake up the proper thread. Finally, process vport loop-resync's only when the vport has in an "active" state (ID acquired).

| | | | | | | | | | | The firmware group has suggested that FCE (Fibre Channel Event) tracing be enabled prior to EFT (Extended Firmware Tracing) to maximize the capturing of data on the wire. This change has no real semantic effect on driver operation, as it's mostly a shuffling of code.

* [SCSI] qla2xxx: Allow the user the option of disabling iIDMA.Andrew Vasquez2008-07-263-1/+10
| | | | | | | | | | | | | | iIDMA support requires the driver issue several additional fabric-managegment (FM) commands per port discovered during SNS scanning -- GFPN (Get Fabric Port Name) and GPSC (Get Port Speed Capabilities). It has been found during testing that some switches do not respond as *well* as expected to these commands (silence -- no ACC nor BS_RJT). So, to handle such conditions, allow the user the ability to indirectly disable the FM commands by disabling iIDMA with the ql2xiidmaenable module-parameter.

* | PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi2008-07-241-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit boundary. For example: u64 val = PAGE_ALIGN(size); always returns a value < 4GB even if size is greater than 4GB. The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for example): #define PAGE_SHIFT 12 #define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT) #define PAGE_MASK (~(PAGE_SIZE-1)) ... #define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK) The "~" is performed on a 32-bit value, so everything in "and" with PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary. Using the ALIGN() macro seems to be the right way, because it uses typeof(addr) for the mask. Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in include/linux/mm.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes two bugs that are related. 1. Old tools did not set can_queue/cmds_max. This patch modifies libiscsi so that when we add the host we catch this and set it to the default. 2. iscsi_tcp thought that the scsi command that was passed to the eh functions needed a iscsi_cmd_task allocated for it. It only needed a mgmt task, and now it does not matter since it all comes from the same pool and libiscsi handles this for the drivers. ib_iser had copied iscsi_tcp's code and set can_queue to its max - 1 to handle this. So this patch removes the max -1, and just sets it to the max. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
