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=3DPACKET, to enable specific remote protocol packets or extensions at startup. Used to add a test for the new 'AlwaysNonStop' extension.

Subject: Re: [PATCH v4 00/11] Add AlwaysNonStop remote protocol exte= nsion

From: "Bouhao= uel, Mohamed" <mohamed.bouhaouel@intel.com>

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 reject= ed
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 t= o
all-stop mode is allowed.

Additionally, added a gdbserver cli option, --enable-packet=3DPACKET, to
enable specific remote protocol packets or extensions at startup.  Use= d
to add a test for the new 'AlwaysNonStop' extension.
