Subject: [PATCH 2/2] rteval: Set higher cyclictest bucket count on non-RT kernels
Date: Wed, 16 Aug 2023 08:57:40 +0200 [thread overview]
Message-ID: <20230816065740.283407-3-tglozar@redhat.com> (raw)
In-Reply-To: <20230816065740.283407-1-tglozar@redhat.com>
Make the default for --cyclictest-buckets 50000 instead of 3500 on
non-RT kernels to make overflowing much less likely.
