NOTE:
	DUD (Driver Update Disk) support is dropped for Citrix's XenServer 6.5 OS,
	XenServer 6.5 OS by default installs the out-of-box megaraid_sas driver while installing the OS.  
	After installing the OS,User can upgrade to the latest megaraid_sas driver just by installing 
	the latest megaraid_sas driver rpm provided by Avago,
 
# rpm -Uvh megaraid_sas-modules-06.807.09.00_CitrixXen6.5-2.x86_64.rpm

How to compile the driver source
================================
Driver source code is placed inside released package,
Driver source tarball- megaraid_sas-<driver_version>-src.tar.gz
To compile the driver for distro, first apply the patch for that distro(Patches are placed inside "patches" directory).

Use below command to apply the patch:
#patch -p1 < xyz.patch (pick the right patch)

To compile the driver for distro use the helper script "compile.sh":
#./compile.sh

Note: For RHEL6 and it's clones(OEL6 and CentOS6), no patches are required to be applied.

If there is no patch inside <patches> direcotry for corresponding Distoro/kernel for which user is trying to compile driver source code 
should pick correct/matching patch from patches directory.
Try to pick patch of closest match of the kernel version from patches directory.  
See below example - ubutu12.4 kernel is close to SLES11SP2 and Ubuntu14.10 kernel version is close to RHEL7.
 
ubuntu12.4  (3.2.0-23-generic)                 sles11-sp2.patch (3.0.13-0.27)
ubuntu14.10 (3.16.0-23-generic)                rhel7.patch (3.10.0-123.el7.x86_64)

Erratas/Notes and some known limitations
################################################################################

------------------------------------------------------------------------------
Oracle Linux Installation errata:
------------------------------------------------------------------------------

1.  Installing Driver during Installing for UEK from CD:

For UEK kernels, only the KMODs RPMs are provided, not the DUDs. The reasoning behind this is the OEL installation is using the native Red Hat kernels, not UEK. UEK kernel RPMS can be installed after the basic installation is complete

2.  Few Known RPM install dependency issues.

E.g. on Oracle Linux 5.7/OVM 3.0.3 KMOD RPM gives kABI checks dependency failure message.

For Oracle Linux 5.7 you will encounter ksym (..) dependency issues,
when installing KMOD package the user will need to use the "--nodeps" switch when installing the binary."

Example: rpm -ivh --nodeps kmod-megaraid_sas-vxxxxxx_UEK.xxx.rpm

"If "rpm -ivh throw any dependancy warning/error"

RPM uses KMOD packaging dependency data to ensure the dependencies are met before installing the binary RPM.
Red Hat maintains a whitelist of kernel symbols which RPM
uses to validate against the KMOD binaries. Some symbols may
be in the kernel but not on the whitelist which results in a failed binary RPM  install. 
The user will need to use the "--nodeps" switch when installing the  binary."

3. In the event of installing UEL and non UEK driver RPMs.      Simultaneously RPM will complain the driver is already installed
the reason is the  major driver version identification string for UEK and the non UEK driver package  RPMS are the same

In this case you can  use rpm --force option to install multiple RPMS.

Example :rpm -ivh  kmod-megaraid_sas-vxxxxxx.xxx.rpm
         rpm --force -ivh kmod-megaraid_sas-vxxxxxx_UEK.xxx.rpm


------------------------------------------------------------------------------
Xen Server Driver update NOTE:
------------------------------------------------------------------------------
 
Known Issue:
In case of Citrix driver update disk use, where system has multiple MegaRAID controller
(at least one MR controller which is supported by Inbox Citrix<megaraid_sas> driver),
user will not see storage behind controller which is not supported by Inbox Driver
(normally this was not expected since user expected driver update disk will work well and 
will detect all controllers)
 
 
Reason for the issue:
Since Xen Server load megaraid_sas driver from inbox before it ask for Driver update disk,
user can see "No Storage Disk" on some servers as explained above.
 
Workaround:
If you are booting from CD, when presented with the 'boot:' prompt you want to type 'shell'
- where you can then rmmod your driver before continuing with the installation.

---------------------------------------------------------------------------
How to Install/upgrade/remove Drivers Ubuntu.
---------------------------------------------------------------------------

-Find below help for verification. Current Driver release has native .deb binary support.

"In Ubuntu all packages are in .deb format. To install .deb packages we have to use the following command,
 		dpkg -i packagename.deb
e.g.: To install above megaraid_sas driver package we use 
dpkg -i megaraid_sas_06.600.00.00-99_amd64.deb

To verify the status of installed packages then type following command
dpkg  -s packagename
e.g: dpkg -s megaraid-sas	

" After installing megaraid_sas driver, now type 
" modinfo megaraid_sas "
Now it should show the currently installed version of megaraid_sas as
" Filename: /lib/modules/2.6.32-33-server/weak-updates/megaraid_sas/megaraid_sas.ko"
 	'Version: 06.600.00.00" (Driver version of in-house deb package)
" Now restart the machine and type following command
" cat /sys/modules/megaraid_sas/version"
  To get currently installed version i.e. it must be correct driver version.
" Now uninstall megaraid_sas package by 
		dpkg -r megaraid-sas
Verify "modinfo megaraid_sas" megaraid_sas version should be in-box version.
		Ubuntu 10.04 LTS has inbox driver version 02.100.03.0.
" Now again restart the machine and type following command
" cat /sys/modules/megaraid_sas/version"
 		It must be "02.100.03.00" (Inbox Driver version)

How to set SMP affinity manually to get better performance under Linux
---------------------------------------------------------------------------
1. Check for the output of "dmesg | grep MSI" to findout total number of MR controller
and its associated MSI-x vectors.
See below example of one MR controller and  current MSIX supported by driver is 24 vector.

e.g:
megaraid_sas 0000:07:00.0: irq 136 for MSI/MSI-X
megaraid_sas 0000:07:00.0: irq 137 for MSI/MSI-X

2. Set SMP affinity manually as shown below:
Actual command syntax is
echo "<value>" > /proc/irq/<irq_number>/smp_affinity

e.g:
echo "1" > /proc/irq/136/smp_affinity (mask 1 for cpu 0)
echo "2" > /proc/irq/137/smp_affinity (mask 10 for cpu 1)
echo "4" > /proc/irq/138/smp_affinity (mask 100 for cpu 2)
echo "8" > /proc/irq/139/smp_affinity (mask 1000 for cpu3)
echo "10" > /proc/irq/140/smp_affinity (mask 10000 for cpu4)
echo "20" > /proc/irq/141/smp_affinity (mask 100000 for cpu5)
echo "40" > /proc/irq/142/smp_affinity (mask 1000000 for cpu6)
echo "80" > /proc/irq/143/smp_affinity (mask 10000000 for cpu7)
.
.
.
.
.
echo "400000" > /proc/irq/158/smp_affinity (mask 10000000000000000000000 for cpu22)
echo "800000" > /proc/irq/159/smp_affinity (mask 100000000000000000000000 for cpu23)

3. By default Irq balancer will be ON,Stop Irq balancer temporarily via below command:
        "chkconfig irqbalance off"
   Verify Irq balancer is stopped via below command:
        "service irqbalance status"


-----------------------------------------------------------------------
How to convert Source RPM to Binary RPM
-----------------------------------------------------------------------

1) Install source RPM like below-

rpm -ivh megaraid_sas-06.809.10.00-1-ubuntu15.4.src.rpm 

2) go to directory where source RPM spec file will be copied-
SPEC file location for RHEL, Ubuntu/Debian based-

cd /root/rpmbuild/SPECS

SPEC file location for SLES based-

cd /usr/src/packages/SPECS

3) There must be specfile(e.g. megaraid_sas-u15.4.spec) inside SPEC file directory. Build binary RPM-
	rpmbuild -ba megaraid_sas-u15.4.spec 

4) cd ../RPMS/

5) Go to cd <arch>, where arch may be- x86_64, i386, ppc64le.... <arch> directory should contain newly generated binary RPM.

Step 6 and 7 are only applicable for Ubuntu/Debian.

6) For Ubuntu and Debian OS, need to conevrt Binary RPM to deb package(for Ubuntu and Debian OS only), do that as below-
	e.g. alien -k --to-deb --scripts megaraid_sas-06.809.10.00-1.ppc64le.rpm 

7) There should be new deb pacakge generated like below-
	megaraid-sas_06.809.10.00-1_ppc64el.deb

10) Added - Enable MSI-X before calling megasas_init_fw().
11) Fixed - Call tasklet_schedule() even if outbound_intr_status == 0 for MFI based boards in MSI-X mode.
  Note: There are now 2 RHEL6 specific 'kmod rpms' in the components.tgz package:
    kmod-megaraid_sas-v00.00.05.33-1.el6.i686.rpm
    kmod-megaraid_sas-v00.00.05.33-1.el6.x86_64.rpm
12) Fixed - megasas_probe_one() to clear PCI_MSIX_FLAGS_ENABLE in msi control register (better kdump MSI-X fix).
13) Fixed - megasas_get_cmd() to only print "Command pool empty" if megasas_dbg_lvl is set
14) Fixed - Sanity check user supplied length in megasas_mgmt_fw_ioctl() to prevent NULL pointer dereference in dma_alloc_coherent() when running smartmontools (From kernel maintainers).
  Note: The MSI-X kdump fix has now been verified by IBM in SLES10-SP4-RC2.
  Note: Please ensure your Linux distribution has 'reset_devices' added to /etc/sysconfig/kdump in the KDUMP_COMMANDLINE_APPEND variable if you are running MSI-X and kdump.
  Note: Smartmontools 5.39 and higher has support for megaraid_sas controllers.
    Usage: smartctl -a -d ir3,X /dev/sdY (X = physical drive DeviceID,
    Y = scsi device driver letter).
15) Added - RHEL5.6 GA support 
16) Fixed - Driver does not expose the cdrom device to kernel.
17) Fixed - expander tool does not work due to enclosure device not exposed by Ir3".
18) Fixed - megasas_slave_configure() to expose all devices that are not TYPE_TAPE or TYPE_DISK.
19) Fixed - megasas_build_dcdb_fusion() to use io_request->LUN[1] field.
20) Fixed - sles10 sp4 regression - kdump Hang issue with Linux driver v5.25.
21) Fixed - megasas_process_interrupt() to handle issue where outbound_intr_status
  (offset 0x30) doesn't show interrupt pending in MSI-X mode in kdump on
  Liberator.
