* [SCSI] qla4xxx: Fix MBOX intr switching from polling to intr mode for ISP83XXVikas Chaudhary2013-01-291-11/+30
| | | | | | | | | | | | | | | | | | | | | | | | Issue: Mailbox command timed out after switching from polling mode to interrupt mode. Events:- 1. Mailbox interrupts are disabled 2. FW generates AEN and at same time driver enables Mailbox Interrupt 3. Driver issues new mailbox to Firmware In above case driver will not get AEN interrupts generated by FW in step #2 as FW generated this AEN when interrupts are disabled. During the same time driver enabled the mailbox interrupt, so driver will not poll for interrupt. Driver will never process AENs generated in step #2 and issues new mailbox to FW, but now FW is not able to post mailbox completion as AENs generated before are not processed by driver. Fix: Enable Mailbox / AEN interrupts before initializing FW in case of ISP83XX. This will make sure we process all Mailbox and AENs in interrupt mode.

| | | | | | | | | | | | | | | | | | | | | | QLogic applications store the CHAP information in FLASH. During login, authentication information is provided using an index into the CHAP region. In order to support QLogic applications along with iscsiadm, updated the LLD to not add duplicate CHAP entries in the CHAP region and preserve the existing CHAP info in the CHAP region in FLASH. This allows QLogic applications to pre-write the CHAP entries in the CHAP region. With iscsiadm, when the CHAP authentication information is sent to the LLD, the LLD searches for the entry in CHAP region in FLASH, if exists then do not add. If CHAP entry does not exist then add the CHAP entry in the CHAP region.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Remove device database entry (ddb) state. 2. Remove device database (DDB) list building. With open-iscsi integration the logins to the target devices are handled by the user space. So the information of target is now maintained in the iscsi_session object. This is handled at libiscsi level so there is no need to maintain a list of DDBs in the qla4xxx LLD. 3. qla4xxx: Remove add_device_dynamically. Since autologin in FW is disabled with open-iscsi integration, driver will never get an AEN for which driver has not requested a DDB index. So remove the add_device_dynamically function. 4. Remove qla4xxx_tgt_dscvr Since firmware autologin is disabled this function will not work. Now user has the ability to do the target discovery and login to each target individually. Firwmare will not do the login on its own. 5. Remove relogin related code All relogin is handled by userspace now. qla4xxx just need to notify userspace of a connection failure, this triggers the relogin. 6. Remove add_session and alloc_session Now qla4xxx uses iscsi_session_setup that would do the necessary allocations for session and ddb_entry.

This patch is based on discussion here http://groups.google.com/group/open-iscsi/browse_thread/thread/e89fd888baf656a0# Now users can use iscsiadm to do target discovery and do login/logout to individual targets using the qla4xxx iSCSI class interface. This patch leaves some dead code, but to make it easier to review we are leaving and in the next patch we will remove that old code. V2 - NOTE: Added code to avoid waiting for AEN during login/logout in the driver, instead added a kernel to user event to notify iscsid about login status. Because of this iscsid will not get blocked.
