This is my first response to a Kernel patch, so I apologise for any formatting weirdness.
I have a Lexar NM790 (4TB), which uses the MAP1602. It looks like this is going to be a fairly popular controller, as it seems a few are using it - as of July 2023 it looks like ~18 M.2 2280 are using it according to techpowerup (https://www.techpowerup.com/ssd-specs/?f&controllerMfgr=Maxiotech#MAP1602).
I however cannot get this patch to work for me on 6.5-rc2 on ArchLinux, nor with 6.4.4.
This is my dmesg when booting (Linux archiso 6.3.9-arch1-1):
[ 6.634874] nvme nvme0: pci function 0000:01:00.0 [ 6.640698] r8169 0000:27:00.0: enabling device (0000 -> 0003) [ 6.643601] nvme nvme0: Device not ready; aborting initialisation, CSTS=0x0
When doing a suspend, then resuming, I can then re-initialise the device using the rescan steps in the previous email.
I then get this in my dmesg (Linux archiso 6.3.9-arch1-1):
[ 130.948667] pci 0000:01:00.0: Removing from iommu group 14 [ 131.983938] pci 0000:01:00.0: [1d97:1602] type 00 class 0x010802 [ 131.983963] pci 0000:01:00.0: reg 0x10: [mem 0xfcf00000-0xfcf03fff 64bit] [ 131.984212] pci 0000:01:00.0: 31.504 Gb/s available PCIe bandwidth, limited by 8.0 GT/s PCIe x4 link at 0000:00:01.1 (capable of 63.012 Gb/s with 16.0 GT/s PCIe x4 link) [ 131.984346] pci 0000:01:00.0: Adding to iommu group 14 [ 132.031556] pci 0000:01:00.0: BAR 0: assigned [mem 0xfcf00000-0xfcf03fff 64bit] [ 132.031662] nvme nvme0: pci function 0000:01:00.0 [ 132.044095] nvme nvme0: allocated 40 MiB host memory buffer.

The "allocated 40 MiB host memory buffer" part is interesting, none of my other drives have this, as this is a DRAM-less drive.
