While at it ensure that "flag_iserror" is only written when "priv_mtx" is locked, which is protecting it. 2015-02-05T20:15:42Z Hans Petter Selasky hselasky@FreeBSD.org 2015-02-05T20:15:42Z urn:sha1:d256fef9e0e95102094b7f6d2a1dac3ec978cfb9 Add 64-bit DMA support in the XHCI controller driver. - Fix some comments and whitespaces while at it. - Add support for PAE. 2014-08-13T08:24:48Z Hans Petter Selasky hselasky@FreeBSD.org 2014-08-13T08:24:48Z urn:sha1:43b4eb6dfc83cc4d19c9626da0ac61eb886deb54 Rename driver name a bit to avoid unit number confusion in dmesg. 2014-06-23T08:28:14Z Marius Strobl marius@FreeBSD.org 2014-06-23T08:28:14Z urn:sha1:87f851a701fa02ad2c692b14677e0fcfd7c3af68 Avoid the USB device disconnected and controller shutdown clutter on system shutdown by putting the former under !rebooting and turning the latter into debug messages.

The deadlock happens because child devices of the USB HUB don't have the expected reference count when called from outside the explore thread. Only the HUB device itself, which the IOCTL interface locks, gets the correct reference count.

The SYSCTL_NODE macro defines a list that stores all child-elements of that node. If there's no SYSCTL_DECL macro anywhere else, there's no reason why it shouldn't be static. 2013-02-21T07:48:07Z Hans Petter Selasky hselasky@FreeBSD.org 2013-02-21T07:48:07Z urn:sha1:4b98c206999a3a320d294c6d2d48072902224251 - Move scratch data from the USB bus structure to the USB device structure so that simultaneous access cannot happen. Protect scratch area using the enumeration lock. - Reduce stack usage in usbd_transfer_setup() by moving some big stack members to the scratch area. This saves around 200 bytes of stack. - Fix a whitespace. - Protect control requests using the USB device enumeration lock. - Make sure all callers of usbd_enum_lock() check the return value. - Remove the control transfer specific lock. - Bump the FreeBSD version number, hence external USB modules may need to be recompiled due to a USB device structure change. 2012-11-08T16:13:51Z Hans Petter Selasky hselasky@FreeBSD.org 2012-11-08T16:13:51Z urn:sha1:36dba61a3a6200609139a96b872a6f707d74561e Add missing CTLFLAG_TUN flag to tunable sysctls in the USB stack. Adjust timing parameters of FULL/LOW/HIGH speed USB enumeration and make these timing parameters tunable. This patch will fix enumeration with some USB devices. Fix a typo.
