Subject: Re: [PATCH v4 00/11] Add AlwaysNonStop remote protocol extension
From: "Bouhaouel, Mohamed" Hi, This series introduces the AlwaysNonStop extension, enabling remote stubs to declare preferable non-stop mode operation. When advertised, GDB defaults to non-stop mode. Attempts to disable it might be rejected by the stub with
a descriptive error message. The V1/V2 approach raised 'O' and 'F' packet compatibility concerns in non-stop mode; this extension-based design addresses those risks (discussed with Pedro Alves). Key change from V3: Relaxed the extension from a must target-non-stop
to a prefer target-non-stop. This will leave it the stub to decide if switching to all-stop mode is allowed. Additionally, added a gdbserver cli option, --enable-packet=PACKET, to enable specific remote protocol packets or extensions at startup. Used to add
a test for the new 'AlwaysNonStop' extension. Link to previous versions: * V3 link: https://inbox.sourceware.org/gdb-patches/20260706121124.18784-1-mohamed.bouhaouel@intel.com/ * V2 link: https://inbox.sourceware.org/gdb-patches/20260611153232.3011-1-mohamed.bouhaouel@intel.com/
