The branch stable/13 has been updated by grehan: URL: https://cgit.FreeBSD.org/src/commit/?id=48214dfab80155c03b9b22aca9f9810774c151e9 commit 48214dfab80155c03b9b22aca9f9810774c151e9 Author: Peter Grehan <grehan@FreeBSD.org> AuthorDate: 2024-01-14 11:27:12 +0000 Commit: Peter Grehan <grehan@FreeBSD.org> CommitDate: 2024-01-28 09:03:25 +0000 Fix issue with Linux guest XHCI tablet probing. The USB3 spec mandates that the device-descriptor max packet size be 512 bytes, which requires a field size of 9 since it is a power-of-2. Linux kernels recently started validating this field, resulting in the table not being probed and the cursor not working in bhyve VNC.
