Public bug reported:
After discussion between Intel and Canonical’s security teams, we are in
agreement that Spectre no longer needs to be mitigated for the GPU at
the Compute Runtime level. At this point, Spectre has been mitigated in
the kernel, and a clear warning from the Compute Runtime build serves as
a warning for those running modified kernels without those patches. For
these reasons, we feel that Spectre mitigations in Compute Runtime no
longer offer enough security impact to justify the current performance
tradeoff.
Intel themselves have disabled this flag in their builds available on
their Github release page upstream.
