Subject: [PATCH 0/2] kgdb: x86: fix breakpoint removal problems
Date: Mon, 12 Aug 2024 01:22:06 +0200 [thread overview]
Message-ID: <20240811232208.234261-1-mail@florommel.de> (raw)
This series fixes two problems with KGDB on x86 concerning the removal
of breakpoints, causing the kernel to hang. Note that breakpoint
removal is not only performed when explicitly deleting a breakpoint,
but also happens before continuing execution or single stepping.
Florian Rommel (2):
x86/kgdb: convert early breakpoints to poke breakpoints
x86/kgdb: fix hang on failed breakpoint removal
