This bug was initially created as a copy of Bug #1674411
I am copying this bug because:
Description of problem:
add support for cascade lake cpu to rhel7
Introduce new cpu model in qemu-kvm for Cascade platform.
instructions detailed info, please ref https://software.intel.com/sites/default/files/managed/c5/15/architecture-instruction-set-extensions-programming-reference.pdf
*** Bug 1674414 has been marked as a duplicate of this bug. ***
I found the patchset to support Cascadelake, and it seems to be ignored.
Patch series adding Cascadelake CPU model and support for MSR features was
sent upstream for review:
This will be addressed in next major release of RHEL.
*** Bug 1758359 has been marked as a duplicate of this bug. ***
Adding Known Issue Doc Text, to make sure the consequences of not having arch-capabilities available are documented.
Based on latest consensus customers will have to use cpu host-passthrough if they require Cascade-Lake capabilities. Closing for RHEL-7.
