In UFS HPB Spec JESD220-3A, "5.8. Active and inactive information upon power cycle ... When the device is powered off by the host, the device may restore L2P map data upon power up or build from the host's HPB READ command. In case device powered up and lost HPB information, device can signal to the host through HPB Sense data, by setting HPB Operation as '2' which will inform the host that device reset HPB information." Therefore, for HPB device control mode, if the UFS device is reset via the RST_N pin, the active region information in the device will be reset. If the host side receives this notification from the device side, it is recommended to inactivate all active regions in the host's HPB cache.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
