With USB-C (with a full implementation, not jokies that just run USB 2 or USB 3 over an USB-C connector) the devices can decide who is host and therefor which device is charging, which outputs display port and those things.
The only reason I can see to add a USB-C to my desktop would be if I get a (cheap enough) phone with USB-C. If the phone does say 5V 3 amps (so up to 15 watts) I'd be thrilled already. The phone might as well have USB 2.0. Thus even a USB-C 2.0 port would do on the desktop lol.
True, if you do have a laptop or tablet thing with Displayport or HDMI on the USB-C you'll need support if you want the USB-C port to do its non USB duty.

ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0",ATTR{queue/scheduler}="bfq"
Depending on your kernel config you may also need below options in grub command line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash scsi_mod.use_blk_mq=y dm_mod.use_blk_mq=y elevator=bfq"

Today, the situation is so bad that the only computer you can buy without spending hours on trying to lookup what the ports actually do is the Macbooks.
It doesn't help that some clusterfuck vendors doesn't specify it at all (looking at you Lenovo) or specify different things on different places (looking at you Asus) so you have to read forum posts of people buying the computers and testing it themselves.

For sending USB-C's advanced stuff (thunderbolt, displayport, whatever else) which is the main reason USB-C exists, you want that subsystem to work.

On desktops it is useful mostly for high speed transfers and moar power. As to get any video output in it you would still need a specific card that has a display port input that comes from your video card, there is no way around that.
Thus even a USB-C 2.0 port would do on the desktop lol.

Thanks for the answers, although NVMe external storage would require Thunderbolt. That's where it gets more hairy I think, it's rather different from USB.
If the external drive is dual mode (PCIe or USB depending on what the host supports) this would work out well but there could be some bugs.
Today, the situation is so bad that the only computer you can buy without spending hours on trying to lookup what the ports actually do is the Macbooks.
But I don't want to nitpick too much ; someday there will be some great mobile hardware thing that will benefit from all that (may I suggest some tablet offer two USB-C port.. or some phone to have micro USB + USB-C so that it can work with all cables and power supplies)Last edited by grok; 01 July 2017, 07:16 PM.

I think it should be visible in sysfs once the switch to blk-mq is done with those scsi_mod=blk-mq parameters. There is another IO scheduler under blk-mq framework in this linux release going by the name of Kyber and is developed by Facebook.
