Subject: [PATCH V2 0/5] ARM64: More flexible HW watchpoint
Date: Thu, 20 Oct 2016 11:18:12 +0530 [thread overview]
Message-ID: <cover.1476941895.git.panand@redhat.com> (raw)
Currently, we do not support all the byte select option provided by ARM64
specs for a HW watchpoint.
This patch set will help user to instrument a watchpoint with all possible
byte select options.
Changes since v1:
Introduced a new patch 3/5 where it takes care of the situation when HW
does not report a watchpoint hit with the address that matches one of the
watchpoints set.
Added corresponding test case to test that functionality.
Pavel Labath (1):
arm64: hw_breakpoint: Handle inexact watchpoint addresses
Pratyush Anand (4):
hw_breakpoint: Allow watchpoint of length 3,5,6 and 7
arm64: Allow hw watchpoint at varied offset from base address
arm64: Allow hw watchpoint of length 3,5,6 and 7
selftests: arm64: add test for unaligned/inexact watchpoint handling
