Subject: x86: Add virtualization time sync support
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=dd30399caefbb5418653f693e9af871741b4d03d;p=openwrt%2Fstaging%2Fdangole.git

x86: Add virtualization time sync support

This compiles the CONFIG_PTP_1588_CLOCK support into the kernel binary
and activates the drivers for KVM and VMware which allow syncing the
host time with the VM when OpenWrt is running in a VM. With this change
the CONFIG_HYPERV_UTILS driver is now build into the kernel, because it
depends on the PTP framework being compiled in. CONFIG_HYPERV_UTILS was
build as a module, but not packages before.

Fixes: #13277
