Subject: [d-kernel] [PATCH 0/5] Kernel 6.18 with support for the Baikal-M SoC
Date: Fri, 24 Apr 2026 18:33:21 +0400
Message-ID: <20260424143329.427971-1-gnusarevda@basealt.ru> (raw)

Патчи для СнК BE-M1000 для работы PCIe шины.
Основной драйвер взят из SDK-ARM64-2509-6.12, доработан для версии 6.18.

Проверена работа на платах:
ET101-MB-v1.1, Элпитех, ПО платы 2409-elp
Родиола MBDR BM12 R000.F01, Delta Computers, ПО платы 5.5
Aquarius, ПО платы 5.3.0
TF307-MB-S-D, ПО платы 5.6 и 2509-6.12

Полноценная работа наблюдается только у плат с обновленным ПО
(TF307 начиная с версии 5.9 и ET101-MB-v1.1 с 2409-elp),
или при указании параметров настройки шины для конкретной платы
в параметрах загрузки ядра (названия перечислены в pcie-baikal-tune.c).

В остальных случаях возможны снижение скорости соединения,
отказ во время установки соединения, неустойчивое соединение вплоть
до нарушения данных.

Daniil Gnusarev (5):
  pci: baikal-pcie: add support for PCIe controller for Baikal BE-M1000
  pci: baikal-pcie: driver compatibility with SDK earlier than 5.7
  pci: baikal-pcie: driver compatibility with SDK versions 5.4
  pci: baikal-pcie: use raw_spinlock for regmap of gbr registers
  pci: baikal-pcie: forced enable dma-coherent for pcie on Baikal-M
