Subject: [PATCH v4 00/10] powerpc/watchpoint: Enable 2nd DAWR on baremetal and powervm
Date: Fri, 17 Jul 2020 09:39:48 +0530 [thread overview]
Message-ID: <20200717040958.70561-1-ravi.bangoria@linux.ibm.com> (raw)
Last series[1] was to add basic infrastructure support for more than
one watchpoint on Book3S powerpc. This series actually enables the 2nd
DAWR for baremetal and powervm. Kvm guest is still not supported.
v3: https://lore.kernel.org/lkml/20200708045046.135702-1-ravi.bangoria@linux.ibm.com
v3->v4:
- v3 patch #2 is split into two v4 patches: #2 and #3
- Few other minor neats suggested by Jordan Niethe
- Rebased to powerpc/next
