Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:
$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..
$ cd build

There are two kinds of HCI implementations. Bluetooth drivers in
drivers/bluetooth that implement HCI by using a wired serial
transport layer to talk to an external controller chip. And a

talks to an internal on-chip controller node.
Currently, when the the subsys/bluetooth/controller is used there
still exists exposed to the user a bluetooth driver configuration
menu, even though no external bluetooth driver is in use. This is due
to a dependency on certain configs in driver/bluetooth that are needed
even though no external controller is used.
This patch moves one of these configs, BLUETOOTH_HCI_RESERVE, from

Since we generate BLUETOOTH_MONITOR_ON_DEV_NAME based on dts we need a
!HAS_DTS check around it. Otherwise we can get into odd build errors.
Its also possibly that we don't specify "zephyr,bt-mon-uart" and in that
case we default to CONFIG_UART_CONSOLE_ON_DEV_NAME (ie 'zephyr,console'
on DTS platforms).

Add an initial implementation for the Bluetooth Mesh Profile
Specification. The main code resides in subsys/bluetooth/host/mesh and
the public API can be found in include/bluetooth/mesh.h. There are a
couple of samples provided as well under samples/bluetooth and
tests/bluetooth.
The implementation covers all layers of the Bluetooth Mesh stack and
most optional features as well. The following is a list of some of
these features and the c-files where the implementation can be found:
- GATT & Advertising bearers (proxy.c & adv.c)
- Network Layer (net.c)
- Lower and Upper Transport Layers (transport.c)
- Access Layer (access.c)
- Foundation Models, Server role (health.c & cfg.c)
- Both PB-ADV and PB-GATT based provisioning (prov.c)
- Low Power Node support (lpn.c)
- Relay support (net.c)
- GATT Proxy (proxy.c)
Notable features that are *not* part of the implementation:
- Friend support (initial bits are in place in friend.c)
- Provisioner support (low-value for typical Zephyr devices)
- GATT Client (low-value for typical Zephyr devices)

Added BUILD_ASSERT check for Tx and Rx thread priorities.
The Tx thread priority shall be higher than Rx thread
priority in order to correctly detect transaction violations
in ATT and SMP protocols. The Number of Completed Packets

The Controller's priority receive thread priority shall be
higher than the Host's Tx and the Controller's Rx thread

There could be situations where many services are changed in a row which
would cause k_sem_take to block on the second change, but if the calling
thread is actually the RX thread then this will deadlock since the RX
thread is the one processing the confirmations of indications and it is
blocked k_sem_give is never called.
To solve this the services changes are now offloaded to the system wq
and the code will attempt to consolidate the range being changed so only
one indication is send. If for some reason another changes is caused
while confirmation is pending we just reschedule it to run later to
avoid blocking the system wq in the same way.

Upcoming memory protection features will be placing some additional
constraints on kernel objects:
- They need to reside in memory owned by the kernel and not the
application
- Certain kernel object validation schemes will require some run-time
initialization of all kernel objects before they can be used.
Per Ben these initializer macros were never intended to be public. It is
not forbidden to use them, but doing so requires care: the memory being
initialized must reside in kernel space, and extra runtime
initialization steps may need to be peformed before they are fully
usable as kernel objects. In particular, kernel subsystems or drivers
whose objects are already in kernel memory may still need to use these
macros if they define kernel objects as members of a larger data
structure.
It is intended that application developers instead use the
K_<object>_DEFINE macros, which will automatically put the object in the
right memory and add them to a section which can be iterated over at
boot to complete initiailization.
There was no K_WORK_DEFINE() macro for creating struct k_work objects,
this is now added.
k_poll_event and k_poll_signal are intended to be instatiated from
application memory and have not been changed.

The following error and warning is received when connecting
to certain central devices:
[bt] [ERR] hci_num_completed_packets: packets count mismatch
[bt] [WRN] bt_att_recv: Ignoring unexpected request
This could happen if Tx-ed packet is not added to pending
list before a num of completed packets event and/or new Rx
packet is received.
This is fixed by reducing the Rx thread priorities in the
Host and the Controller.

It's possible that the controller will emit the number of completed

In order to properly queue request there need to be a bt_att_req
