Date: Wed, 12 Feb 2020 21:11:29 -0600 From: minyard@....org To: Catalin Marinas <catalin.marinas@....com>, Will Deacon <will@...nel.org>, linux-arm-kernel@...ts.infradead.org Cc: linux-kernel@...r.kernel.org Subject: [RFC PATCH 0/2] arm64 kgdb fixes for single stepping I got a bug report about using kgdb on arm64, and it turns out it was fairly broken. Patch 2 has a description of what was going on. I am using a Marvell 8100 board. The following patches fix the problem, but probably not in the best way. They are what I hacked out to show the problems. I am not quite sure how this will interact with kprobes and hardware breakpoints which use the same code, but they would have been broken, too, so this is not making them any worse.
