they occur. This prevents repeated notifications of the same event. Status of these events may be viewed at any time by viewing the SMART/Health Info Page using nvmecontrol, whether or not asynchronous events notifications for those events are enabled. This log page can be viewed using: nvmecontrol logpage -p 2 Future enhancements may re-enable these notifications on a periodic basis so that if the notified condition persists, it will continue to be logged.

Change the way that unmapped I/O capability is advertised.

2013-08-15T22:52:39Z

The previous method was to set the D_UNMAPPED_IO flag in the cdevsw for the driver. The problem with this is that in many cases (e.g. sa(4)) there may be some instances of the driver that can handle unmapped I/O and some that can't. The isp(4) driver can handle unmapped I/O, but the esp(4) driver currently cannot. The cdevsw is shared among all driver instances. So instead of setting a flag on the cdevsw, set a flag on the cdev. This allows drivers to indicate support for unmapped I/O on a per-instance basis. sys/conf.h: Remove the D_UNMAPPED_IO cdevsw flag and replace it with an SI_UNMAPPED cdev flag. kern_physio.c: Look at the cdev SI_UNMAPPED flag to determine whether or not a particular driver can handle unmapped I/O. geom_dev.c: Set the SI_UNMAPPED flag for all GEOM cdevs. Since GEOM will create a temporary mapping when needed, setting SI_UNMAPPED unconditionally will work. Remove the D_UNMAPPED_IO flag. nvme_ns.c: Set the SI_UNMAPPED flag on cdevs created here if NVME_UNMAPPED_BIO_SUPPORT is enabled. vfs_aio.c: In aio_qphysio(), check the SI_UNMAPPED flag on a cdev instead of the D_UNMAPPED_IO flag on the cdevsw. sys/param.h: Bump __FreeBSD_version to 1000045 for the switch from setting the D_UNMAPPED_IO flag in the cdevsw to setting SI_UNMAPPED in the cdev.
