Subject: [PATCH 0/7] ARM: hw_breakpoint: fix reset sequence for debug arch v7.1
Date: Wed, 17 Oct 2012 16:31:34 +0100 [thread overview]
Message-ID: <1350487901-3108-1-git-send-email-will.deacon@arm.com> (raw)
Hello,
This set of patches fixes the hw_breakpoint debug register reset sequence
for ARM debug architecture v7.1. This involves:
- Probing of the save/restore registers on v7
- Avoiding the use of DBGDSCRint.HDBGen, which is now UNKNOWN
- Only attempt to enable monitor mode during boot, then check
whether it is still enabled during breakpoint validation
- Some minor changes to remain compatible with v6 processors
All feedback welcome,
Will

ARM: hw_breakpoint: only clear OS lock when implemented on v7
ARM: hw_breakpoint: fix monitor mode detection with v7.1
ARM: hw_breakpoint: fix ordering of debug register reset sequence
ARM: hw_breakpoint: don't try to clear v6 debug registers during boot
ARM: hw_breakpoint: make boot quieter without CPUID feature registers
ARM: hw_breakpoint: check if monitor mode is enabled during
validation
