Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+Release Date    : Thu Feb 03 12:27:22 EST 2005 - Seokmann Ju <sju@lsil.com>
+Current Version : 2.20.4.5 (scsi module), 2.20.2.5 (cmm module)
+Older Version   : 2.20.4.4 (scsi module), 2.20.2.4 (cmm module)
+
+1.      Modified name of two attributes in scsi_host_template.

+
+        These are, perhaps, slightly confusing names.
+        The terms device and class_device have well defined meanings in the
+        generic device model, neither of which is what you mean here.
+        Why not simply megaraid_sdev_attrs and megaraid_shost_attrs?
+
+        Other than this, it looks fine to me too.

+Release Date    : Thu Jan 27 00:01:03 EST 2005 - Atul Mukker <atulm@lsil.com>
+Current Version : 2.20.4.4 (scsi module), 2.20.2.5 (cmm module)
+Older Version   : 2.20.4.3 (scsi module), 2.20.2.4 (cmm module)
+
+1.      Bump up the version of scsi module due to its conflict.
+
+Release Date    : Thu Jan 21 00:01:03 EST 2005 - Atul Mukker <atulm@lsil.com>
+Current Version : 2.20.4.3 (scsi module), 2.20.2.5 (cmm module)
+Older Version   : 2.20.4.2 (scsi module), 2.20.2.4 (cmm module)
+
+1.      Remove driver ioctl for logical drive to scsi address translation and
+        replace with the sysfs attribute. To remove drives and change
+        capacity, application shall now use the device attribute to get the
+        logical drive number for a scsi device. For adding newly created
+        logical drives, class device attribute would be required to uniquely
+        identify each controller.
+                - Atul Mukker <atulm@lsil.com>
+
+        "James, I've been thinking about this a little more, and you may be on
+        to something here. Let each driver add files as such:"

+
+        "Then, if you simply publish your LD number as an extra parameter of
+        the device, you can look through /sys to find it."
+
+                - James Bottomley <James.Bottomley@SteelEye.com>, 01.03.2005

+
+
+        "I don't see why not ... it's your driver, you can publish whatever
+        extra information you need as scsi_device attributes; that was one of
+        the designs of the extensible attribute system."

+                - James Bottomley <James.Bottomley@SteelEye.com>, 01.06.2005

+
+2.      Add AMI megaraid support - Brian King <brking@charter.net>
+                PCI_VENDOR_ID_AMI, PCI_DEVICE_ID_AMI_MEGARAID3,
+                PCI_VENDOR_ID_AMI, PCI_SUBSYS_ID_PERC3_DC,
+
+3.      Make some code static - Adrian Bunk <bunk@stusta.de>
+        Date:   Mon, 15 Nov 2004 03:14:57 +0100
+
+        The patch below makes some needlessly global code static.
+        -wait_queue_head_t wait_q;
+        +static wait_queue_head_t wait_q;
+
+        Signed-off-by: Adrian Bunk <bunk@stusta.de>
+
+4.      Added NEC ROMB support - NEC MegaRAID PCI Express ROMB controller
+                PCI_VENDOR_ID_LSI_LOGIC, PCI_DEVICE_ID_MEGARAID_NEC_ROMB_2E,
+                PCI_SUBSYS_ID_NEC, PCI_SUBSYS_ID_MEGARAID_NEC_ROMB_2E,
+
+5.      Fixed Tape drive issue : For any Direct CDB command to physical device
+        including tape, timeout value set by driver was 10 minutes. With this 
+        value, most of command will return within timeout. However, for those
+        command like ERASE or FORMAT, it takes more than an hour depends on
+        capacity of the device and the command could be terminated before it 
+        completes.
+        To address this issue, the 'timeout' field in the DCDB command will 
+        have NO TIMEOUT (i.e., 4) value as its timeout on DCDB command.

+Older Version   : 2.20.4.1 (scsi module), 2.20.2.3 (cmm module)
+
+i.      Introduced driver ioctl that returns scsi address for a given ld.
+        
+        "Why can't the existing sysfs interfaces be used to do this?"
+                - Brian King (brking@us.ibm.com)

+
+i.      Fix a bug in kioc's dma buffer deallocation
+
+Release Date    : Thu Nov  4 18:24:56 EST 2004 - Sreenivas Bagalkote <sreenib@lsil.com>
+
+Current Version : 2.20.4.1 (scsi module), 2.20.2.2 (cmm module)
+Older Version   : 2.20.4.0 (scsi module), 2.20.2.1 (cmm module)
+
+i.      Handle IOCTL cmd timeouts more properly.
+
+ii.     pci_dma_sync_{sg,single}_for_cpu was introduced into megaraid_mbox
+        incorrectly (instead of _for_device). Changed to appropriate 
+        pci_dma_sync_{sg,single}_for_device.

+Older Version   : 2.20.3.1 (scsi module), 2.20.2.0 (cmm module)
+
+i.      Fix data corruption. Because of a typo in the driver, the IO packets
+        were wrongly shared by the ioctl path. This causes a whole IO command
+        to be replaced by an incoming ioctl command.

+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)
+

+
+ii.     Display elapsed time (countdown) while waiting for FW to boot.
+
+iii.    Module compilation reorder in Makefile so that unresolved symbols do
+        not occur when driver is compiled non-modular.

+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)
+
+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.
+

+
+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."

+                 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.

+Current Version : 2.20.0.0

+
+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

+        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

+
+        "pci_id_table_g would be much more readable when not using C99

+
+                - 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.
