Collection of SAMSUNG NVMe SSD firmware

Almost all modern SSD drives support firmware upgrade via NVM Express commands. For linux you can use https://github.com/linux-nvme/nvme-cli

As we see the disk support Firmware Image Download command (0x1 FW Commit and Download Supported), has 3 Firmware Slots (0x3 Number of Firmware Slots) and 1st Firmware Slot in Read/Write mode(0 Firmware Slot 1 Read/Write) but I don’t recommend using it.. Try to use free Firmware Slot, do not overwrite the original firmware.

Lets download firmware to controller SRAM

$ sudo nvme fw-download -f firmware.bin /dev/nvme0 Firmware download success 

Write firmware to free Firmware Slot 2 without activation

$ sudo nvme fw-commit -s 2 -a 0 /dev/nvme0 Success committing firmware action:0 slot:2 

 $ sudo nvme fw-commit -s 2 -a 2 /dev/nvme0 Success committing firmware action:2 slot:2

режим работы Samsung NVMe SM951 в Ubuntu 16.4.1

Прошу помощи по решению следующего вопроса: SAMSUNG MZHPV256HDGL-00000 в убунте работает под управлением драйвера ядра ahci вместо nvme.

Тестовое запускал под виндой и на ней все в порядке — определяется и работает полноценно, а тут такая петрушка.

Как привести в чувство (к работе под управлением драйвера ядра nvme)?

Вывод команд для анализа.
