Subject: [PATCH] app/dma-perf: fixes buffer overflow error
Date: Wed, 25 Feb 2026 17:11:20 +0530	[thread overview]
Message-ID: <20260225114120.2036-1-vipin.varghese@amd.com> (raw)

test-dma-perf limits the number of worker thread to 128.
The current change accomadates to RTE_MAX_LCORES. This allows
high core density platforms to run the test on `(RTE_MAX_LCORE - 1)`

Without the change we encounter `buffer overflow detected, terminated`.

Fixes: 623dc9364dc6 ("app/dma-perf: introduce DMA performance test")
