User guides and additional HP Network Adapter information can be found at: http://h18004.www1.hp.com/products/servers/networking/index-nic.html Packaging ========= The driver is released in Kernel Module Package (KMP) source RPM format. KMP packages use macros that determine kernel flavors for which binary packages need to be built based on spec file rules. It is important to have the right build environment set up in order to compile a binary RPM from the source package. See "Build Environment Setup" section below. This package also builds a "doc" package which includes a README and man page for this driver. Build Environment Setup ======================== The tg3 package requires the presence of some packages that provide the right build environment. These packages provide kernel headers, makefiles and symbol files, though the last one is suggested only on SLES distributions. RHEL installation: 1. redhat-rpm-config package 2. kernel-devel-<kernel_version> package 3. kernel-<flavor>-devel-<kernel_version> package Eg: kernel-2.6.18.92.el5 requires kernel-devel-2.6.18-92.el5 kernel-PAE-2.6.18.92.el5 requires kernel-PAE-devel-2.6.18-92.el5 See the "Caveats" section below for more details. SLES Installation: 1. kernel-source-<kernel_version> package 2. kernel-syms-<kernel_version> package 3. SLES11 requires kernel-<flavor>-devel-<kernel_version> package as well Installing the RPM Package ============================= 1. This package requires a build environment. Please refer to the "Build Environment Setup" Section before proceding to the next step. 2. Install the source RPM package. # rpm -ivh hp-tg3-<version>.src.rpm 3. Build the binary RPM for the tg3 driver. RHEL 5: # rpmbuild -bb /usr/src/redhat/SPECS/hp-tg3.spec RHEL 6: # rpmbuild -bb ~/rpmbuild/SPECS/hp-tg3.spec SLES: # rpmbuild -bb /usr/src/packages/SPECS/hp-tg3.spec If you get an error during the build process, refer to the "Build Environment Setup" section. NOTE: One can build binary RPM for a specfic kernel flavor as follows: # rpmbuild -bb SPECS/hp-tg3.spec --define "KVER <kver>" NOTE: RHEL 5 x86 installations require the "--target" switch when building on Intel compatible machines. Please see the "Caveats" section below for more details. # rpmbuild --target=i686 -bb /usr/src/redhat/SPECS/hp-tg3.spec 4. Check for the existence of a current version of the tg3 package as follows: RHEL # rpm -q kmod-hp-tg3-<flavor> SLES # rpm -q hp-tg3-kmp-<flavor> If an old version of the package exists, the RPM package should be removed. Remove the corresponding tools package before removing driver package. RHEL # rpm -e kmod-hp-tg3-<flavor> SLES # rpm -e hp-tg3-kmp-<flavor> Verify if the old hp-tg3 package has been removed as follows: RHEL # rpm -q kmod-hp-tg3-<kernel flavor> SLES # rpm -q hp-tg3-kmp-<kernel flavor> 5. Install the new binary RPM package. RHEL 5 # rpm -ivh \ /usr/src/redhat/RPMS/<arch>/kmod-hp-tg3-<flavor>-<version>.<arch>.rpm RHEL 6 # rpm -ivh \ ~/rpmbuild/RPMS/<arch>/kmod-hp-tg3-<flavor>-<version>.<arch>.rpm The modules are installed in the following directory: /lib/modules/<kernel_version>/extra/hp-tg3 Note: The "--nodeps" switch is required when installing to RHEL 5.4 and RHEL 5.5. See the "Caveats" section below for more details. # rpm -ivh \ /usr/src/redhat/RPMS/<arch>/kmod-hp-tg3-<flavor>-<version>.<arch>.rpm --nodeps SLES # rpm -ivh RPMS/<arch>/hp-tg3-kmp-<version>-<flavor>.<arch>.rpm The modules are installed in the following directory: /lib/modules/<kernel_version>/updates/hp-tg3 6. Configure your network setting and address. You may need to refer to your Linux vendor documentation. Helpful network configuration tools such as "yast2" in SLES or linuxconf/redhat-config-network/netconfig in Red Hat exist for easy configuration. For SLES, you must specify the module as tg3 while configuring the network. The module can be specified in Hardware Details of Advanced configuration 7. Ensure that the /etc/modules.conf file is configured similar to the example listed below. The example below is presented as if more than one adapter is present. If so, one eth# instance should exist for each Ethernet port. Refer to the modules.conf man page for more information. alias eth0 tg3 alias eth1 tg3 alias eth# tg3 For SLES, the configuration file is /etc/modprobe.conf or /etc/modprobe.conf.local Note: If the above entry does not exist, add it in the configuration file. 8. Reboot the server or restart the network services. Upon reboot the network should start with tg3 driver loaded To verify that the driver is loaded, use the following command. # lsmod You should find tg3 listed. Use ifconfig to bring up the network with the new driver: # ifconfig eth# up Refer to the man pages for lsmod, ifconfig, rmmod, insmod, modprobe, modules.conf and modprobe.conf for more detailed information. Driver Settings ================= tg3 driver settings can be queried and changed using ethtool. The latest ethtool can be downloaded from http://sourceforge.net/projects/gkernel if not already installed. See the ethtool man page for more information. ethtool settings do not persist across reboot or module reload. To preserve the setting across reboots, you can do the following - RHEL : a) Add appropriate 'ethtool' commands to /etc/rc.local as follows ethtool -s ethX speed 10 b) 'ethtool -s' parameters can be specified in the ifcfg-ethX scripts using the ETHTOOL_OPTS keyword. Example: /etc/sysconfig/network-scripts/ifcfg-ethX: ETHTOOL_OPTS="wol g speed 100 duplex half autoneg off" SLES: a) Modify /etc/sysconfig/network/config to have following options set to 'yes'. GLOBAL_POST_UP_EXEC="yes" GLOBAL_PRE_DOWN_EXEC="yes" b) Create a script file (E.g, ethtool-settings) in /etc/sysconfig/network/if-up.d directory with required ethtool commands. Example: the file can contain the following ethtool command /usr/sbin/ethtool -s ethX speed 10 c) Set the mode of the file to 777. #chmod +777 ethtool-settings This will ensure that the script is executed each time interface is brought up. The complete set of Module Parameters supported by the tg3 driver is described in the README.TXT which is installed under the appropriated directories as mentioned in the Introduction section. Module Parameters can be queried and changed using ethtool. Driver Messages =============== The following are the most common sample messages that may be logged in the file /var/log/messages. Some Linux distributions may not display messages to the console. To set messages to display on the console, at the command line use the following to control the level at which messages will appear on the console. # dmesg -n 6 Most systems are set to level 6 by default. Uninstalling the RPM ==================== The following command will uninstall the RPM. RHEL # rpm -e kmod-hp-tg3-<kernel flavor> SLES # rpm -e hp-tg3-kmp-<kernel flavor> Caveats =========== 1. The rpmbuild will fail the dependency check when building the non-base (xen,pae,etc) kernel when the kernel-devel package is not installed. Example: If the OS only included the PAE kernel then the user would need to install the kernel-pae-devel and kernel-devel packages. 2. The use of a "--target" switch is required so that rpmbuild does not try to find an i386 kernel on the system. If the "--target" switch is not used then the build will fail with bizarre messages stating that specific kernel packages are not installed on the machine yet those packages do not exist. 3. The rpmbuild will fail if the redhat-rpm-config package is not installed because it cannot resolve the %kernel_module_package_buildreqs macro. The error will be similar to the following: error: line xx: Dependency tokens must begin with alpha-numeric,'_'or'/': Build Requires: %kernel_module_package_buildreqs 4. RPM uses KMP 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 KMP 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. The tg3 packaged drivers uses the following symbols on RedHat EL5 Update 3, Update 4 and Update 5 that are not on the whitelist: Update 4 ksym(pci_enable_msi) ksym(pci_disable_msi) Update 3 ksym(pcie_set_readrq) (C) Copyright 2002, 2003 - 2011 Hewlett-Packard Development Company, L.P.
