CPU_FTR_DAWR is by default enabled for host via CPU_FTRS_DT_CPU_BASE (controlled by CONFIG_PPC_DT_CPU_FTRS). But cpu-features device-tree node is not PAPR compatible and thus not yet used by kvm or pHyp guests. Enable watchpoint functionality on power10 guest (both kvm and powervm) by adding CPU_FTR_DAWR to CPU_FTRS_POWER10. Note that this change does not enable 2nd DAWR support.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
