Zephyr deprecated and then removed its stack_analyze function because it
was unsafe. Use the new zephyr thread analyzer instead and rename the
MicroPython function to zephyr.thread_analyze() to be more consistent with
the implementation.
Tested on mimxrt1050_evk.
The output now looks like this:
>>> zephyr.thread_analyze()
Thread analyze:
80004ff4 : unused 400 usage 112 / 512 (21 %)
rx_workq : unused 1320 usage 180 / 1500 (12 %)
tx_workq : unused 992 usage 208 / 1200 (17 %)
net_mgmt : unused 656 usage 112 / 768 (14 %)
sysworkq : unused 564 usage 460 / 1024 (44 %)
idle : unused 256 usage 64 / 320 (20 %)
main : unused 2952 usage 1784 / 4736 (37 %)
Note: the uncrustify configuration is explicitly set to 'add' instead of
'force' in order not to alter the comments which use extra spaces after //
as a means of indenting text for clarity.
Introduces a new zephyr.FlashArea class that uses the zephyr flash map
api to implement the uos.AbstractBlockDev protocol. The flash driver is
enabled on the frdm_k64f board, reel_board, and rv32m1_vega_ri5cy board.
The standard and extended block device protocols are both supported,
therefore this class can be used with file systems like littlefs which
require the extended interface.
Introduces a new zephyr.DiskAccess class that uses the zephyr disk
access api to implement the uos.AbstractBlockDev protocol. This can be
used with any type of zephyr disk access driver, which currently
includes SDHC, RAM, and FLASH implementations. The SDHC driver is
enabled on the mimxrt1050_evk board.
Only the standard block device protocol (without the offset parameter)
can be supported with the zephyr disk access api, therefore this class
cannot be used with file systems like littlefs which require the
extended interface. In the future it may be possible to implement the
extended interface in a new class using the zephyr flash api.
Zephyr restructured its includes in v2.0 and removed compatibility shims
after two releases in commit 1342dadc365ee22199e51779185899ddf7478686.
Updates include paths in MicroPython accordingly to fix build errors in
the zephyr port.
These changes are compatible with Zephyr v2.0 and later.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
