Hi support,

This is HighPoint, we are a manufacturer of storage solutions. Recently, some of our customers reported that HighPoint SSD7000 NVMe series products cannot be used normally in Arch Linux.

After our analysis, it was confirmed that Arch Linux integrated the built-in NVMe driver into the kernel, so that the third-party NVMe driver we provided could not be loaded preferentially.

Is it possible to load the built-in NVMe driver as a module?
In this way, third-party NVMe drivers can be supported on the one hand, and existing functions are not affected on the other hand.

Looking forward to your reply, thank you.
This task depends upon

module_blacklist= or initcall_blacklist= on kernel commandline is not an option?

initcall_blacklist=nvme_init should disable the built-in nvme module.

It works. But we hope that:
load HighPoint third-party NVMe driver for NVMe devices connected to HighPoint SSD7000 controller.
load built-in NVMe driver for NVMe devices connect to motherboard.

so we hope that HighPoint third-party NVMe driver and built-in NVMe driver can exist at the same time.
