2006-03-26[PATCH] mempool: use common mempool kmalloc allocatorMatthew Dobson
This patch changes several mempool users, all of which are basically just wrappers around kmalloc(), to use the common mempool_kmalloc/kfree, rather than their own wrapper function, removing a bunch of duplicated code.

dual channel adapters Introduce lpfc_reset_barrier() function for resets on dual channel adapters Workaround for a hardware errata on dual channel asics. There is a potential for the chip to lock up on a reset if a shared dma engine is in use. The (ugly) work around requires a reset process which uses a mailbox command to synchronize the independent channels prior to the reset to avoid the issue. Unfortunately, the timing windows required to ensure this workaround succeeds are very specific, meaning we can't release the cpu during the barrier.

Fix deadlock in lpfc_fdmi_tmo_handler lpfc_fdmi_tmo_handler was calling lpfc_fdmi_cmd with the host_lock held. lpfc_fdmi_cmd assumes the host_lock is released as it calls functions that acquire the host_lock. lpfc_fdmi_tmo_handler acquired the host_lock to protect access to work_hba_events. This was already checked in the worker thread so we can remove that code completely and remove access to the host_lock.

2005-12-13[SCSI] lpfc 8.1.1 : Add polled-mode supportJames.Smart@Emulex.Com
- Add functionality to run in polled mode only. Includes run time attribute to enable mode. - Enable runtime writable hba settings for coallescing and delay parameters Customers have requested a mode in the driver to run strictly polled. This is generally to support an environment where the server is extremely loaded and is looking to reclaim some cpu cycles from adapter interrupt handling. This patch adds a new "poll" attribute, and the following behavior: if value is 0 (default): The driver uses the normal method for i/o completion. It uses the firmware feature of interrupt coalesing. The firmware allows a minimum number of i/o completions before an interrupt, or a maximum time delay between interrupts. By default, the driver sets these to no delay (disabled) or 1 i/o - meaning coalescing is disabled. Attributes were provided to change the coalescing values, but it was a module-load time only and global across all adapters. This patch allows them to be writable on a per-adapter basis. if value is 1 : Interrupts are left enabled, expecting that the user has tuned the interrupt coalescing values. When this setting is enabled, the driver will attempt to service completed i/o whenever new i/o is submitted to the adapter. If the coalescing values are large, and the i/o generation rate steady, an interrupt will be avoided by servicing completed i/o prior to the coalescing thresholds kicking in. However, if the i/o completion load is high enough or i/o generation slow, the coalescion values will ensure that completed i/o is serviced in a timely fashion. if value is 3 : Turns off FCP i/o interrupts altogether. The coalescing values now have no effect. A new attribute "poll_tmo" (default 10ms) exists to set the polling interval for i/o completion. When this setting is enabled, the driver will attempt to service completed i/o and restart the interval timer whenever new i/o is submitted. This behavior allows for servicing of completed i/o sooner than the interval timer, but ensures that if no i/o is being issued, then the interval timer will kick in to service the outstanding i/o.
