Subject: [PATCH v4 0/5] Powerpc/Watchpoint: Few important fixes
Date: Wed, 25 Sep 2019 09:36:25 +0530	[thread overview]
Message-ID: <20190925040630.6948-1-ravi.bangoria@linux.ibm.com> (raw)

v3: https://lists.ozlabs.org/pipermail/linuxppc-dev/2019-July/193339.html

v3->v4:
 - Instead of considering exception as extraneous when dar is outside of
   user specified range, analyse the instruction and check for overlap
   between user specified range and actual load/store range.
 - Add selftest for the same in perf-hwbreak.c
 - Make ptrace-hwbreak.c selftest more strict by checking address in
   check_success.
 - Support for 8xx in ptrace-hwbreak.c selftest (Build tested only)
 - Rebase to powerpc/next

@Christope, Can you please check Patch 5. I've just build-tested it
with ep88xc_defconfig.

Ravi Bangoria (5):
  Powerpc/Watchpoint: Fix length calculation for unaligned target
  Powerpc/Watchpoint: Don't ignore extraneous exceptions blindly
  Powerpc/Watchpoint: Rewrite ptrace-hwbreak.c selftest
  Powerpc/Watchpoint: Add dar outside test in perf-hwbreak.c selftest
  Powerpc/Watchpoint: Support for 8xx in ptrace-hwbreak.c selftest
