Subject: [PATCH 04/25] kernel-yocto: Simplify code for cleanliness and slight performance
Date: Sun,  2 Aug 2026 11:28:33 +0100	[thread overview]
Message-ID: <20260802102854.3952760-5-richard.purdie@linuxfoundation.org> (raw)
In-Reply-To: <20260802102854.3952760-1-richard.purdie@linuxfoundation.org>

Checking "in d" is really slow, using getVar for a specific lookup
is much much faster.

The externalsrc issue can be resolved more simply by adding an extra
constraint on the kernel_configme task.
