Subject: [PATCH v5 0/7] Powerpc/Watchpoint: Few important fixes
Date: Mon, 14 Oct 2019 18:33:39 +0530 [thread overview]
Message-ID: <20191014130346.22660-1-ravi.bangoria@linux.ibm.com> (raw)
v4: https://lists.ozlabs.org/pipermail/linuxppc-dev/2019-September/197621.html
v4->v5:
- patch 1,2,3/7: Split v4 patch1 into three differnet patches.
* 1st patch to replace hardcoded watchpoint length with macros
* 2nd patch that fixes the unaligned watchpoint issue
* 3rd patch that fixes ptrace code that mucks around address/len
- patch 3/7: v4 patch1 was creating a regression in watchpoint length
calculation in ptrace code. Fixed that.
- patch 7/7: Disabled MODE_RANGE and 512 byte testcases for 8xx. (Build
tested only)
- patch 7/7: Unaligned watchpoints are not supported with DABR. Test
unaligned watchpoint only when DAWR is present.

Powerpc/Watchpoint: Introduce macros for watchpoint length
