Merge patch series "Uthreads"

2025-04-23T19:21:39+00:00

Jerome Forissier  says:

This series introduces threads and uses them to improve the performance
of the USB bus scanning code and to implement background jobs in the
shell via two new commands: 'spawn' and 'wait'.

The threading framework is called 'uthread' and is inspired from the
barebox threads [2]. setjmp() and longjmp() are used to save and
restore contexts, as well as a non-standard extension called initjmp().
This new function is added in several patches, one for each
architecture that supports HAVE_SETJMP. A new symbol is defined:
HAVE_INITJMP. Two tests, one for initjmp() and one for the uthread
scheduling, are added to the lib suite.

After introducing threads and making schedule() and udelay() a thread
re-scheduling point, the USB stack initialization is modified to benefit
from concurrency when UTHREAD is enabled, where uthreads are used in
usb_init() to initialize and scan multiple busses at the same time.
The code was tested on arm64 and arm QEMU with 4 simulated XHCI buses
and some devices. On this platform the USB scan takes 2.2 s instead of
5.6 s. Tested on i.MX93 EVK with two USB hubs, one ethernet adapter and
one webcam on each, "usb start" takes 2.4 s instead of 4.6 s.

Finally, the spawn and wait commands are introduced, allowing the use of
threads from the shell. Tested on the i.MX93 EVK with a spinning HDD
connected to USB1 and the network connected to ENET1. The USB plus DHCP
init sequence "spawn usb start; spawn dhcp; wait" takes 4.5 seconds
instead of 8 seconds for "usb start; dhcp".

test: run some test commands only if HUSH_PARSER is enabled

2025-04-22T18:26:41+00:00

Some test commands (such as "false", or the empty string) need
CONFIG_HUSH_PARSER=y. Fix test/cmd/command.c.

Kbuild: Always use $(PHASE_)

2025-04-11T18:16:44+00:00

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our
Makefiles as part of the macros to determine when to do something in our
Makefiles based on what phase of the build we are in. For consistency,
bring this down to a single macro and use "$(PHASE_)" only.

cmd/setexpr: support concatenation of direct strings

2025-02-07T19:35:23+00:00

The setexpr.s command allows to concatenate two strings.

According to the description in doc/usage/cmd/setexpr.rst the parameters
value1 and value2 can be either direct values or pointers to a
memory location holding the values.

Unfortunately `setexpr.s  + ` fails if any of the values
is a direct value. $? is set to false.

* Add support for direct values in setexpr.s.
* Correct the unit test for "setexpr.s fred 0".
* Add a new unit test for "setexpr.s fred '1' + '3'" giving '13'.

test: remove available memory check in setexpr_test_str_oper()

2025-02-07T19:35:23+00:00

env_set() frees the previous value after allocating the new value.
As the free() may merge memory chunks the available memory is not
expected to stay constant.

test/cmd/wget.c: Fix loadaddr rewrite

2025-01-27T18:46:44+00:00

The $loadaddr variable is a hexadecimal value, not a string, it must be
assigned using env_set_hex(). This may break follow up tests, like the
dm_test_cmd_hash_md5 in CI. To avoid any interference with other tests,
set $wgetaddr variable which is specific to this test and use it in the
test.
