Subject: [d-kernel] [PATCH 0/1] Ядро 6.12 с поддержкой СнК Байкал-М
Date: Thu, 14 Aug 2025 15:40:24 +0400
Message-ID: <20250814114027.60916-1-gnusarevda@basealt.ru> (raw)
При задействовании init_on_alloc выявилась проблема с когерентностью при
работе с PCIe шиной. По предложению Байкал Электроникс в описание шин в dts
добавлено (правда напрямую через драйвер, при запуске) свойство 'dma-coherent'.
При этом ошибки исчезли. Проверялась работа nvme на разных машинах, на TF-307
кроме этого проверялась работа при разных SKD, с nvme и внешней PCIe видеокартой.
