This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

There's a driver to support this but upstream doesn't like it for reasons like NVMe quirks can't be applied when NVMe are behind AHCI controller. So we need to devise a mechanism to ask users to change BIOS storage settings. This patch only provides a new attribute to let userspace like distro installer know NVMe is remapped behind AHCI. [Fix] Add a new attribute to show that how many NVMes are remapped. [Test] After applying the patch, there's a new "remapped_nvme" under the AHCI PCI device sysfs. If there's no remapped NVMe: $ cat remapped_nvme 0 If there are two remapped NVMes: $ cat remapped_nvme 2 [Regression Potential] Low. It adds a new read only sysfs attribute, no actual functional change to the AHCI driver.
