Based on v3.5. Used to shorten git clone time. Note: the regular Linux git tree can be used as well. compat: ------- URL: git://git.openfabrics.org/compat-rdma/compat.git Branch: ofed - Based on compat project (https://github.com/mcgrof/compat). The compat module provides functionality introduced in newer kernels to older kernels through a set of header files and exported symbols. See https://github.com/mcgrof/compat/wiki for details. - Used to replace kernel_addons in the previous OFED kernel tree. compat-rdma: ------------ URL: git://git.openfabrics.org/compat-rdma/compat-rdma.git Branch: master User level Sources are downloaded from http://www.openfabrics.org/downloads/ as written in the BUILD_ID The kernel sources are based on Linux 3.5 mainline kernel. Its patches are included in the OFED sources directory. For details see HOWTO.build_ofed.

Change log =============================================================================== OFED-3.5-1 Main Changes from OFED 3.5 ------------------------------------------------------------------------------- 1. Based on linux-3.5 kernel 2. Added support for the OSes: - RHEL 6.4 3. Updated packages: - none =============================================================================== 3. Known Issues =============================================================================== The following is a list of general limitations and known issues of the various components of the OFED 3.5-1-rc1 release. 1. When upgrading from an earlier OFED version, the installation script does not stop the earlier OFED version prior to uninstalling it. Workaround: Stop the old OFED stack (/etc/init.d/openibd stop) before upgrading to OFED 3.5 or reboot the server after OFED installation. 2. Memory registration by the user is limited according to administrator setting. See "Pinning (Locking) User Memory Pages" in OFED_tips.txt for system configuration. 3. Fork support from kernel 2.6.12 and above is available provided that applications do not use threads. fork() is supported as long as the parent process does not run before the child exits or calls exec(). The former can be achieved by calling wait(childpid), and the latter can be achieved by application specific means. The Posix system() call is supported. 4. The qib driver is supported only on 64-bit platforms. 5. IPoIB: brctl utilities do not work on IPoIB interfaces. The reason for that is that these utilities support devices of type Ethernet only. 6. In case uninstall is failing, check the error log and remove the remaining RPMs manually using 'rpm -e '. 7. On SLES11.x, set allow_unsupported_modules parameter to 1 in file: /etc/modprobe.d/unsupported-modules. Without this the modules will not load. 8. RDS is supported only on kernel.org 3.5 and not on any distro OS. Note: See the release notes of each component for additional issues.
