The following handshake mechanism needs be followed after firmware download is completed to bring the firmware to running state. After firmware fragments of Operational image are downloaded and secure sends result of the image succeeds, 1. Driver sends HCI Intel reset with boot option #1 to switch FW image. 2. FW sends Alive GP[0] MSIx 3. Driver enables data path (doorbell 0x460 for RBDs, etc...) 4. Driver gets Bootup event from firmware 5. Driver performs D0 entry to device (WRITE to IPC_Sleep_Control =0x0) 6. FW sends Alive GP[0] MSIx 7. Device host interface is fully set for BT protocol stack operation. 8. Driver may optionally get debug event with ID 0x97 which can be dropped For Intermediate loadger image, all the above steps are applicable expcept #5 and #6. On HCI_OP_RESET, firmware raises alive interrupt. Driver needs to wait for it before passing control over to bluetooth stack.

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 reStructuredText 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.
