Documentation/scsi/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.
+Release Date	: Tue Aug 24 09:43:35 EDT 2004 - Atul Mukker <atulm@lsil.com>
+Current Version	: 2.20.3.1 (scsi module), 2.20.2.0 (cmm module)
+Older Version	: 2.20.3.0 (scsi module), 2.20.2.0 (cmm module)
 
-	Also, do not wait on status be become 0xFF, since FW can return this
-	status in certain circumstances.
+i.	Function reordering so that inline functions are defined before they
+	are actually used. It is now mandatory for GCC 3.4.1 (current stable)
 
-	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
+	Declare some heavy-weight functions to be non-inlined,
+	megaraid_mbox_build_cmd, megaraid_mbox_runpendq,
+	megaraid_mbox_prepare_pthru, megaraid_mbox_prepare_epthru,
+	megaraid_busywait_mbox
 
-ii.	Specify the logical drive number while issuing the RESERVATION_STATUS
+		- Andrew Morton <akpm@osdl.org>, 08.19.2004
+		linux-scsi mailing list
 
-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.
+	"Something else to clean up after inclusion: every instance of an
+	inline function is actually rendered as a full function call, because
+	the function is always used before it is defined.  Atul, please
+	re-arrange the code to eliminate the need for most (all) of the
+	function prototypes at the top of each file, and define (not just
+	declare with a prototype) each inline function before its first use"
 
-iv.	The max outstanding commands are reduced to 126 because that't the
-	safest value on all FW.
+		- Matt Domsch <Matt_Domsch@dell.com>, 07.27.2004
+		linux-scsi mailing list
 
-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.
+ii.	Display elapsed time (countdown) while waiting for FW to boot.
 
-### Version: 2.00.2
-i.	Intermediate release with kernel specific code
+iii.	Module compilation reorder in Makefile so that unresolved symbols do
+	not occur when driver is compiled non-modular.
 
+		Patrick J. LoPresti <patl@users.sourceforge.net>, 8.22.2004
+		linux-scsi mailing list
 
-### 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
 
+Release Date	: Thu Aug 19 09:58:33 EDT 2004 - Atul Mukker <atulm@lsil.com>
+Current Version	: 2.20.3.0 (scsi module), 2.20.2.0 (cmm module)
+Older Version	: 2.20.2.0 (scsi module), 2.20.1.0 (cmm module)
 
-### 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.
+i.	When copying the mailbox packets, copy only first 14 bytes (for 32-bit
+	mailboxes) and only first 22 bytes (for 64-bit mailboxes). This is to
+	avoid getting the stale values for busy bit. We want to set the busy
+	bit just before issuing command to the FW.
+
+ii.	In the reset handling, if the reseted command is not owned by the
+	driver, do not (wrongly) print information for the "attached" driver
+	packet.
+
+iii.	Have extended wait when issuing command in synchronous mode. This is
+	required for the cases where the option ROM is disabled and there is
+	no BIOS to start the controller. The FW starts to boot after receiving
+	the first command from the driver. The current driver has 1 second
+	timeout for the synchronous commands, which is far less than what is
+	actually required. We now wait up to MBOX_RESET_TIME (180 seconds) for
+	FW boot process.
+
+iv.	In megaraid_mbox_product_info, clear the mailbox contents completely
+	before preparing the command for inquiry3. This is to ensure that the
+	FW does not get junk values in the command.
+
+v.	Do away with the redundant LSI_CONFIG_COMPAT redefinition for
+	CONFIG_COMPAT. Replace <asm/ioctl32.h> with <linux/ioctl32.h>
+
+		- James Bottomley <James.Bottomley@SteelEye.com>, 08.17.2004
+		 linux-scsi mailing list
+
+vi.	Add support for 64-bit applications. Current drivers assume only
+	32-bit applications, even on 64-bit platforms. Use the "data" and
+	"buffer" fields of the mimd_t structure, instead of embedded 32-bit
+	addresses in application mailbox and passthru structures.
+
+vii.	Move the function declarations for the management module from
+	megaraid_mm.h to megaraid_mm.c
+
+		- Andrew Morton <akpm@osdl.org>, 08.19.2004
+		linux-scsi mailing list
+
+viii.	Change default values for MEGARAID_NEWGEN, MEGARAID_MM, and
+	MEGARAID_MAILBOX to 'n' in Kconfig.megaraid
+
+		- Andrew Morton <akpm@osdl.org>, 08.19.2004
+		linux-scsi mailing list
+
+ix.	replace udelay with msleep
+
+x.	Typos corrected in comments and whitespace adjustments, explicit
+	grouping of expressions.
+
+
+Release Date	: Fri Jul 23 15:22:07 EDT 2004 - Atul Mukker <atulm@lsil.com>
+Current Version	: 2.20.2.0 (scsi module), 2.20.1.0 (cmm module)
+Older Version	: 2.20.1.0 (scsi module), 2.20.0.0 (cmm module)
+
+i.	Add PCI ids for Acer ROMB 2E solution
+
+ii.	Add PCI ids for I4
+
+iii.	Typo corrected for subsys id for megaraid sata 300-4x
+
+iv.	Remove yield() while mailbox handshake in synchronous commands
+
+
+	"My other main gripe is things like this:
+
+	+	// wait for maximum 1 second for status to post
+	+	for (i = 0; i < 40000; i++) {
+	+		if (mbox->numstatus != 0xFF) break;
+	+		udelay(25); yield();
+	+	}
+
+	which litter the driver.  Use of yield() in drivers is deprecated."
+
+		- James Bottomley <James.Bottomley@SteelEye.com>, 07.14.2004
+		 linux-scsi mailing list
+
+v.	Remove redundant __megaraid_busywait_mbox routine
+
+vi.	Fix bug in the managment module, which causes a system lockup when the
+	IO module is loaded and then unloaded, followed by executing any
+	management utility. The current version of management module does not
+	handle the adapter unregister properly.
+
+	Specifically, it still keeps a reference to the unregistered
+	controllers. To avoid this, the static array adapters has been
+	replaced by a dynamic list, which gets updated every time an adapter
+	is added or removed.
+
+	Also, during unregistration of the IO module, the resources are
+	now released in the exact reverse order of the allocation time
+	sequence.
+
+
+Release Date	: Fri Jun 25 18:58:43 EDT 2004 - Atul Mukker <atulm@lsil.com>
+Current Version	: 2.20.1.0
+Older Version	: megaraid 2.20.0.1
+
+i.	Stale list pointer in adapter causes kernel panic when module
+	megaraid_mbox is unloaded
+
+
+Release Date	: Thu Jun 24 20:37:11 EDT 2004 - Atul Mukker <atulm@lsil.com>
+Current Version	: 2.20.0.1
+Older Version	: megaraid 2.20.0.00
+
+i.	Modules are not 'y' by default, but depend on current definition of
+	SCSI & PCI.
+
+ii.	Redundant structure mraid_driver_t removed.
+
+iii.	Miscellaneous indentation and goto/label fixes.
+		- Christoph Hellwig <hch@infradead.org>, 06.24.2004 linux-scsi
+
+iv.	scsi_host_put(), do just before completing HBA shutdown.
+
+
+
+Release Date	: Mon Jun 21 19:53:54 EDT 2004 - Atul Mukker <atulm@lsil.com>
+Current Version	: 2.20.0.0
+Older Version	: megaraid 2.20.0.rc2 and 2.00.3
+
+i.	Independent module to interact with userland applications and
+	multiplex command to low level RAID module(s).
+
+	"Shared code in a third module, a "library module", is an acceptable
+	solution. modprobe automatically loads dependent modules, so users
+	running "modprobe driver1" or "modprobe driver2" would automatically
+	load the shared library module."
+
+		- Jeff Garzik <jgarzik@pobox.com> 02.25.2004 LKML
+
+	"As Jeff hinted, if your userspace<->driver API is consistent between
+	your new MPT-based RAID controllers and your existing megaraid driver,
+	then perhaps you need a single small helper module (lsiioctl or some
+	better name), loaded by both mptraid and megaraid automatically, which
+	handles registering the /dev/megaraid node dynamically. In this case,
+	both mptraid and megaraid would register with lsiioctl for each
+	adapter discovered, and lsiioctl would essentially be a switch,
+	redirecting userspace tool ioctls to the appropriate driver."
+
+		- Matt Domsch <Matt_Domsch@dell.com> 02.25.2004 LKML
+
+ii.	Remove C99 initializations from pci_device id.
+
+	"pci_id_table_g would be much more readable when not using C99
+	initializers.
+	PCI table doesn't change, there's lots of users that prefer the more
+	readable variant.  And it's really far less and much easier to grok
+	lines without C99 initializers."
+
+		- Christoph Hellwig <hch@infradead.org>, 05.28.2004 linux-scsi
+
+iii.	Many fixes as suggested by Christoph Hellwig <hch@infradead.org> on
+	linux-scsi, 05.28.2004
+
+iv.	We now support up to 32 parallel ioctl commands instead of current 1.
+	There is a conscious effort to let memory allocation not fail for ioctl
+	commands.
+
+v.	Do away with internal memory management. Use pci_pool_(create|alloc)
+	instead.
+
+vi.	Kill tasklet when unloading the driver.
+
+vii.	Do not use "host_lock', driver has fine-grain locks now to protect all
+	data structures.
+
+viii.	Optimize the build scatter-gather list routine. The callers already
+	know the data transfer address and length.
+
+ix.	Better implementation of error handling and recovery. Driver now
+	performs extended errors recovery for instances like scsi cable pull.
+
+x.	Disassociate the management commands with an overlaid scsi command.
+	Driver now treats the management packets as special packets and has a
+	dedicated callback routine.

+			Notes on Management Module
+			~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Overview:
+--------
+
+Different classes of controllers from LSI Logic, accept and respond to the
+user applications in a similar way. They understand the same firmware control
+commands. Furthermore, the applications also can treat different classes of
+the controllers uniformly. Hence it is logical to have a single module that
+interefaces with the applications on one side and all the low level drivers
+on the other.
+
+The advantages, though obvious, are listed for completeness:
+
+	i.	Avoid duplicate code from the low level drivers.
+	ii.	Unburden the low level drivers from having to export the
+		character node device and related handling.
+	iii.	Implement any policy mechanisms in one place.
+	iv.	Applications have to interface with only module instead of
+		multiple low level drivers.
+
+Currently this module (called Common Management Module) is used only to issue
+ioctl commands. But this module is envisioned to handle all user space level
+interactions. So any 'proc', 'sysfs' implementations will be localized in this
+common module.
+
+Credits:
+-------
+
+"Shared code in a third module, a "library module", is an acceptable
+solution. modprobe automatically loads dependent modules, so users
+running "modprobe driver1" or "modprobe driver2" would automatically
+load the shared library module."
+
+		- Jeff Garzik (jgarzik@pobox.com), 02.25.2004 LKML
+
+"As Jeff hinted, if your userspace<->driver API is consistent between
+your new MPT-based RAID controllers and your existing megaraid driver,
+then perhaps you need a single small helper module (lsiioctl or some
+better name), loaded by both mptraid and megaraid automatically, which
+handles registering the /dev/megaraid node dynamically. In this case,
+both mptraid and megaraid would register with lsiioctl for each
+adapter discovered, and lsiioctl would essentially be a switch,
+redirecting userspace tool ioctls to the appropriate driver."
+
+		- Matt Domsch, (Matt_Domsch@dell.com), 02.25.2004 LKML
+
+Design:
+------
+
+The Common Management Module is implemented in megaraid_mm.[ch] files. This
+module acts as a registry for low level hba drivers. The low level drivers
+(currently only megaraid) register each controller with the common module.
+
+The applications interface with the common module via the character device
+node exported by the module.
+
+The lower level drivers now understand only a new improved ioctl packet called
+uioc_t. The management module converts the older ioctl packets from the older
+applications into uioc_t. After driver handles the uioc_t, the common module
+will convert that back into the old format before returning to applications.
+
+As new applications evolve and replace the old ones, the old packet format 
+will be retired.
+
+Common module dedicates one uioc_t packet to each controller registered. This
+can easily be more than one. But since megaraid is the only low level driver
+today, and it can handle only one ioctl, there is no reason to have more. But
+as new controller classes get added, this will be tuned appropriately.

+ *			Handle 64K limits on many controllers
+ *			Don't use indirects on the Promise (breaks)
+ *			Heavily chop down the queue depths
+ *		Deepak Saxena:

+ *			Support for dynamic device creation/deletion
+ *			Code cleanup
+ *	    		Support for larger I/Os through merge* functions
+ *			(taken from DAC960 driver)
+ *		Boji T Kannanthanam:

+ *			Search and set the I2O block device that we boot off
+ *			from as the first device to be claimed (as /dev/i2o/hda)
+ *			Properly attach/detach I2O gendisk structure from the
