Subject: [PATCH 42/53] Add support for NVMe devices
|
||
|
|
|
||
|
|
Recognize NVMe Devices, so "parted -s /dev/nvme0n1" now prints
|
||
|
|
"NVMe Device (nvme)" instead of "Model: Unknown (unknown)".
|
||
|
|
|
||
|
|
In order for a device to be recognized as NVMe, it has to
|
||
|
|
have a 'blkext' major number. But since this major can be
|
||
|
|
used also by other device types, we also check the device
|
||
|
|
path contains 'nvme' as a substring.
|
||
|
|
|
||
|
|
* NEWS: Mention the change
|
||
|
|
* include/parted/device.h.in(PedDeviceType): Add PED_DEVICE_NVME
|
||
|
|
* libparted/arch/linux.c(BLKEXT_MAJOR): New define.
|
||
|
|
* libparted/arch/linux.c(_is_blkext_major): New function.
|
||
|
|
* libparted/arch/linux.c(_device_probe_type): Recognize NVMe devices.
|
||
|
|
* libparted/arch/linux.c(linux_new): Handle NVMe devices.
|
||
|
|
* parted/parted.c(do_print): Add "nvme" to list of transports.
