I have released the latest 2.00.3 driver (2.4) kernel. Mark, I will
incorporate your changes for the 2.5 kernel and release the patch again
soon.

The driver is mailed separately to Matt. He will update it on his server as
he always does :-)

Changelog.megaraid

### Version 2.00.3
Wed Jan 29 09:13:44 EST 200 - Atul Mukker <atulm@lsil.com>
i.	Change the handshake in ISR while acknowledging interrupts. Write
the
	valid interrupt pattern 0x10001234 as soon as it is read from the
	outdoor register. In existing driver and on certain platform,
invalid
	command ids were being returned.

	Also, do not wait on status be become 0xFF, since FW can return this
	status in certain circumstances.

	Initialize the numstatus field of mailbox to 0xFF so that we can
wait
	on this wait in next interrupt. Firmware does not change its value
	unless there are some status to be posted

ii.	Specify the logical drive number while issuing the
RESERVATION_STATUS

iii.	Reduce the default mailbox busy wait time from 300us to 10us. This
is
	done to avaoid a possible deadlock in FW because of longer bust
waits.

iv.	The max outstanding commands are reduced to 126 because that't the
	safest value on all FW.

v.	Number of sectors per IO are reduced to 128 (64kb), becuase FW needs
	resources in special circumstances like check consistency, rebuilds
	etc.

vi.	max_commands is no longer a module parameter because of iv.

### Version: 2.00.2
i.	Intermediate release with kernel specific code


### Version: 2.00.1i
Wed Dec  4 14:34:51 EST 2002 - Atul Mukker <atulm@lsil.com>
i.	Making the older IO based controllers to work with this driver


### Version 2.00.1
Fri Nov 15 10:59:44 EST 2002 - Atul Mukker <atulm@lsil.com>
i.	Release host lock before issuing internal command to reset
	reservations in megaraid_reset() and reacquire after internal
command
	is completed.

Thanks

Thanks Mark.  I appreciate you keeping megaraid2 updated recently.

FYI, my ability to post to bkbits.net is extremely limited right now. 
Hopefully I'll have that resolved in a few weeks.

Atul Mukker from LSI is coordinating all the megaraid driver work now. 
I'll try to help from time to time, but my other duties dictate I leave
day-to-day megaraid maintenance and publishing to Atul, who is the
formal maintainer.  I do expect this list will continue to be active for
driver maintenance.

Thanks,
Matt
