uninstall samsung nvme controller driver

Surface NVM Express Controller driver manufacturer is Controlador Standard NVM Express and developed by Microsoft in the database contains 1 versions of the Surface NVM Express Controller. Just got an open collection of manufacturers and KB3087873 patches. nvme nvme1: pci function 0004:05:00.Download Now MICROSOFT STANDARD NVM EXPRESS DRIVER pci 0004:02:03.0: PME# supported from D0 D1 D2 D3hot D3cold Same thing happens if I first remove only the switch port the CFX card is connected to. If I only do a rescan without first executing remove the following dmesgs are thrown. We would need to be able to hotplug / hotswap the CFX card connected to the pcie switch without removing the whole switch and interrupting the connection to the other devices on the switch though. $ sudo sh -c 'echo 1 > /sys/bus/pci/rescan' *** boot system without CFX card attached

Hotswapping works as well by removing the root port befor detaching the CFX card and rescaning. It works like you suggested by removing the root port and rescaning. Is there any way to hotplug an nvme if it is connected to the root port via a pcie switch? With a rescan the CFX is enumerated but no nvme device is created. $ sudo cat /sys/kernel/debug/pcie-4/hot_plug If the CFX card is plugged in after the system booted and I execute the hotplug sysfs command for the switch nothing happens. sudo lspciĠ004:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad1 (rev a1)Ġ004:01:00.0 PCI bridge: Pericom Semiconductor Device 2404 (rev 05)Ġ004:02:01.0 PCI bridge: Pericom Semiconductor Device 2404 (rev 05)Ġ004:02:02.0 PCI bridge: Pericom Semiconductor Device 2404 (rev 05)Ġ004:02:03.0 PCI bridge: Pericom Semiconductor Device 2404 (rev 05)Ġ004:03:00.0 RAM memory: Xilinx Corporation Device d021Ġ004:05:00.0 Non-Volatile memory controller: Device 1987:5013 (rev 01)Ġ005:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad0 (rev a1)Ġ005:01:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd NVMe SSD Controller SM981/PM981

If the CFX card is pluggin in before the system is booted it enumerates as 0004:05:00.0 Non-Volatile memory controller and works as expected. We now would need to hotplug / hotswap a NVMe ( CFX Card to be precise ) that is connected to the Xavier NX via a PCIe switch ( Pericom PI7C9X2G ). Got another question expanding on the problem concerning NVMe hotplugging / hotswapping you helped me with back in February.
