| This newsletter covers changes in Zephyr between these two commits: | |
| - 4291fb67a ("usb: Remove duplicated CDC_ECM_SUBCLASS definition"), Apr 4 2018 | |
| - 9bde3c06e ("tests: build_all: Add LPS22HB and LSM6DSL sensors build test"), | |
| Apr 10 2018 | |
| The most significant of these changes are due to a large re-work of | |
| the SPI APIs, which affected both the peripheral drivers themselves as | |
| well as their users. | |
| Important Changes | |
| ----------------- | |
| SPI API | |
| ~~~~~~~ | |
| The SPI API (in include/spi.h) has been re-worked and finalized. All | |
| in-tree users were upgraded to the new API. The old SPI API, and all | |
| of its implementations, have been removed. Out of tree uses of the old | |
| SPI API will need updates. A summary of the API changes follows. | |
| The I/O APIs now use a new struct spi_buf_set, which contains a | |
| pointer to a struct spi_buf array, and its length: | |
| struct spi_buf_set { | |
| const struct spi_buf *buffers; | |
| size_t count; | |
| }; | |
| This structure is used in the I/O APIs so that the TX and RX | |
| arguments can be specified in two formal parameters, which allows | |
| using registers instead of the stack in some API calls. | |
| All SPI API calls also now take a pointer to the SPI device itself as | |
| their first parameter, instead of storing that device in struct | |
| spi_config. This makes the SPI API consistent with other Zephyr device | |
| APIs. | |
| The "EEPROM mode" support was removed from the master controller | |
| operations bit mask. It was replaced with a new flag, | |
| SPI_CS_ACTIVE_HIGH, which inverts the usual polarity of the chip | |
| select pin. | |
| The spi_config parameter passed to the SPI API is now constant, | |
| allowing it to be stored in flash memory. | |
| The asynchronous SPI API no longer uses CONFIG_POLL directly. Instead, | |
| a layer of indirection through CONFIG_SPI_ASYNC was introduced, which | |
| selects CONFIG_POLL. | |
| In addition to these changes in the SPI master mode API, experimental | |
| support for SPI slave implementations was added to the new API. | |
| Board Porting Guidelines | |
| ~~~~~~~~~~~~~~~~~~~~~~~~ | |
| Official board porting guidelines were merged, which have consistent | |
| rules for how to structure a board's Kconfig. For details, refer here: | |
| http://docs.zephyrproject.org/porting/board_porting.html#default-board-configuration | |
| Features | |
| -------- | |
| VLAN support: | |
| VLAN support was added for Ethernet network interfaces. Initial | |
| support is provided for mcux, native POSIX, and Atmel E70. The | |
| SLIP driver also has VLAN support. | |
| New net shell commands "net vlan", "net vlan add", and "net vlan | |
| del" were added to query and manipulate the VLAN configuration. | |
| A new sample application, samples/net/vlan, was added, which can | |
| be used to set VLAN tags for ethernet interfaces. | |
| As part of these and other network changes, the ethernet files now | |
| live in their own directory, net/ip/l2/ethernet. | |
| Red/black trees: | |
| A new red/black balanced binary tree implementation was added; the | |
| API is available in include/misc/rb.h. Like the linked list types, | |
| the structure is *intrusive*: red-black tree nodes are meant to be | |
| embedded in another structure, which contains the user data | |
| associated with that node. Code size compared to a doubly linked | |
| list on most architectures is approximately an additional 2-2.5 | |
| KB. | |
| Completion of DTS support for I2C and SPI on STM32: | |
| All STM32-based boards now use device tree for I2C and SPI | |
| peripherals. | |
| Bluetooth generalizations: | |
| Continuing the effort to generalize the core Bluetooth subsystem | |
| across SoCs, the Bluetooth "ticker" timing API now includes a | |
| generic hal/ticker.h file, which abstracts out SoC specific | |
| definitions. | |
| Drivers: | |
| Ethernet is now enabled by default on the sam_e70_xplained board. | |
| New driver support includes SPI on nRF52, an interrupt in transfer | |
| callback on USB HID, USB CDC EEM support for encapsulating | |
| Ethernet packets over a USB transport, and GPIO triggering for the | |
| ST LSM6DSL accelerometer and IMU. | |
| Boards: | |
| New boards include the SiFive HiFive1 and Nordic nRF52 | |
| Thingy:52 (PCA20020). | |
| Speeding up CI: | |
| An effort is underway to reduce the amount of time spent in CI. To | |
| that end, an additional CI build slave was added, some duplicative | |
| test coverage on qemu_x86 and qemu_cortex_m32 was eliminated, and | |
| other optimizations were performed. | |
| Boot banner changes: | |
| The boot banner now prints the git version (based on git describe) | |
| and hash, but timestamps were removed from it by default to | |
| increase the reproducibility of Zephyr builds. | |
| User mode memory pools: | |
| A new memory pool implementation which is compatible with use from | |
| user mode threads was merged; the API is available in | |
| include/misc/mempool.h. This implementation shares code with the | |
| in-kernel k_mem_pool API, but avoids constraints that are | |
| incompatible with user mode. Memory pools are defined at compile | |
| time with SYS_MEM_POOL_DEFINE(), and initialized by | |
| sys_mem_pool_init(). Memory may be allocated and freed from an | |
| initialized memory pool with sys_mem_pool_alloc() and | |
| sys_mem_pool_free(), respectively. | |
| Network interface management: | |
| Interface statistics collection is now per-interface. | |
| The network shell command "net iface" can now enable or disable | |
| network interfaces by index. | |
| Initial support for ethernet interface configuration has been | |
| merged. This includes a link speed capabilities query. An API was | |
| also merged for changing hardware configuration; this includes | |
| link speed, but is not limited to it. | |
| Bug Fixes | |
| --------- | |
| Support for enabling GPIO port H on STM32L0 was fixed. | |
| Support accessing sub-region attributes on ARM MPUs was fixed. | |
| A pair of Bluetooth mesh fixes were merged, including a null | |
| dereference and an issue related to enabling node identity | |
| advertising. | |
| The behavior of the CONFIG_FP_SOFTABI option was fixed. It now | |
| generates floating point instructions, rather than turning them off, | |
| which it was doing previously. | |
| The temperature sensor channel for the nRF TEMP IP block was fixed; it | |
| is now SENSOR_CHAN_DIE_TEMP. | |
| A fix was merged for k_thread_create(), which now properly checks | |
| the provided stack size on systems which enforce power of two sizes. | |
| POSIX fixes for pthread_cancel and timer_gettime were merged. | |
| Dozens of commits cleaning up and fixing the test cases were merged. | |
