1. Feature Overview:
a) Name of feature:
VMware Paravirtual RDMA User Library (libvmw_pvrdma).
b) Feature Description:
VMware recently added a paravirtual RDMA device to vSphere 6.5. We have also
upstreamed the driver for Linux with Linux Kernel 4.10 as well as the user library.
This feature request is to add the corresponding user library from upstream rdma-
core repository to RHEL-based Guest Operating Systems.
2. Feature Details:
a) Architectures:
64-bit Intel EM64T/AMD64
b) Bugzilla Dependencies:
1454965.
c) Drivers or hardware dependencies:
rdma-core. PVRDMA Driver.
d) Upstream acceptance information:
Present as a new provider in rdma-core release v13. Commit
b6b0734abcceb167c2820e96f0891b6cae7b59e9.
e) External links:
https://github.com/linux-rdma/rdma-core/tree/master/providers/vmw_pvrdma
f) Severity (H,M,L): H
g) Feature Needed by:
RHEL 7.4 GA. This feature would allow VMware customers to deploy and use RHEL-based
VMs with PVRDMA devices. The library would allow guest user-space applications to
bypass the guest OS when issuing RDMA operations to the PVRDMA device.
3. Business Justification:
Same as above.
libvmw_pvrdma had been imported to rdma-core-13-5.el7.
rpm -qpl libibverbs-13-5.el7.x86_64.rpm | grep vmw_pvrdma
/etc/libibverbs.d/vmw_pvrdma.driver
/usr/lib64/libibverbs/libvmw_pvrdma-rdmav2.so
This request came in long after the planning and development phases for 7.4. The criteria for taking in a new driver has not been met. Please work with your engineering partner manager to get this criteria satisfied for a future version of RHEL.
This will not be supported in 7.4.
Thank you
