menuconfig RT_USING_NVME

default n
help
Enable the NVMe driver stack so PCIe-connected SSDs can be discovered,
command queues created, and block devices exported through the block
layer. Requires DMA and the driver model; disable if your platform lacks
NVMe hardware.
config RT_USING_NVME_IO_QUEUE
int "Number of I/O Command queue"
depends on RT_USING_NVME
default 2 if RT_THREAD_PRIORITY_8
default 4 if RT_THREAD_PRIORITY_32
default 8 if RT_THREAD_PRIORITY_256
help
Set how many submission/completion queue pairs to create for NVMe I/O.
More queues improve parallelism on multicore systems but consume more DMA
memory and interrupts.
config RT_NVME_PCI
bool "NVME support on PCI bus"
depends on RT_USING_NVME
depends on RT_USING_PCI
default y
help
Allow the driver to bind to NVMe controllers discovered via PCI/PCIe.
Disable only for non-PCI environments (for example, custom interconnects).
