Fantasic! You are solving one of my local TODOs :)

Can you make all these USB changes belonging together a stack in Phabricator?
It's a bit hard to grasp which all are there or belong together.
I'd be happy to at least scroll through them even if I cannot review them all in detail most likely.

    TODO usb: add USB_SPEED_SUPER_PLUS to enum usb_dev_speed
    
    While nothing in our native USB stack uses the USB 3.1 "SUPERSPEED+"
    setting yet, a LinuxKPI based wireless driver does check for it.
    
    TODO: The arrays in usbd_get_std_packet_size() likely need to be updated.

Hi bz@, Thanks for your reply. I might not know what is the correct way to do so. But I think in the stack tab, all of my patches can be seen in here.

I do not see any changes to usb_transfer.c in the stack.
That likely means usbd_get_std_packet_size() array accesses may get out of bounds accesses?
If I am right, this should be addressed somewhere before this or other bits go in.

Expose pcidev/drm

LG for implementation part.

CC releng because this should go into 14.5, IMO, which might mean an expedited MFC. I think this is reasonably safe.

@kevans Could you please check if there is any regression on your yubikey? Thanks!

This commit make cheap USB memory key to not attach - see below.
The commit works with Samsung memory keys.
Maybe this is correct and the necessary change to get the cheap noname USB memory keys to work needs to be done in some other place.

Bug fixes

@bapt Hi, My version has been merged by @emaste. Could you please close this?

@bz if you don't have any problem. I will merge this ptach next week.

LGTM!

LGTM

It needs rebase. Do it tomorrow.

Oh, I can re-commit this version. Let me bring it back later.

It is merged by upstream. Close this now

I have merged the 1.9 -> 1.8 patch to main first. Other things fixed. Thanks!

Reflect markj@ and kib@'s comment

Anyway. Thanks!

Versioning

Hi, symbol versioning patch is merged. Please rebase and do necessary change.

Hmm, I missed that the LLVM change has not yet landed. @zishun.yi.dev_gmail.com will you add some tests as requested in the PR? If that's done, I wonder if @dim or @aokblast can help land it?

Checked by readelf to see whether all of the public symbols have inside.

Add new missing ABI and bump shlib version

Do you mean https://reviews.freebsd.org/D54987? I was typing something while you leave your comment:)

No, I mean more changes to be added to the stack; when I first did this it was a/multiple year(s) ago. I put some of that out earlier this year in order to get the de-coupling of LinuxKPI from the native stack structures out but that got into controversial discussions. In the follow-up I added more stuff for more USB wifi drivers ... which I never uploaded to Phab.

I'll go through what you have and would love to put a new stack up next week, if that's okay?

LGTM. Waiting for the feedback from @glebius :)

Plus these points, usb_unlink_urb_sub bypass unanchored in not started yet branch. Causing a forever run if the xfer hasn't start yet. Also, we need usb_put_urb in the same point

hi, it would be better to commit D57759, right? I can commit that patch for you.

usbconfig stopped reporting my webcam and fingerprint reader. Instead I get 'usbconfig: could not open device: Bad file descriptor'. Problem goes away when these changes are reverted. A very strange side note: libusb20_int.h is missing from base.txz for 15.1-RELEASE (but is in src.txz). I think the problem is I'm testing against 15.1-RELEASE which is too far behind current. I need to find some hardware onto which I can run current.

I would just abandon it as somebody has much more decent works.

LGTM. Sorry that I though it was copy and paste from line 633. It should work. Thanks!

Also, we should use peek flag in native in here.

LGTM with the style change. I can commit this after @glebius accept.
