tools: gpio: Fix several incorrect format specifiers

2024-11-13T15:30:05+00:00

Make a minor change to eliminate static checker warnings. The variable lines[] is unsigned, so the correct format specifier should be %u instead of %d. Signed-off-by: Luo Yifan Link: https://lore.kernel.org/r/20241113021458.291252-1-luoyifan@cmss.chinamobile.com Signed-off-by: Bartosz Golaszewski

gpio: add sloppy logic analyzer using polling

2024-07-01T08:54:11+00:00

This is a sloppy logic analyzer using GPIOs. It comes with a script to isolate a CPU for polling. While this is definitely not a production level analyzer, it can be a helpful first view when remote debugging. Read the documentation for details.

tools: gpio: fix -c option of gpio-event-mon

2023-01-27T13:05:46+00:00

Following line should listen for a rising edge and exit after the first one since '-c 1' is provided. # gpio-event-mon -n gpiochip1 -o 0 -r -c 1 It works with kernel 4.19 but it doesn't work with 5.10. In 5.10 the above command doesn't exit after the first rising edge it keep listening for an event forever. The '-c 1' is not taken into an account. The problem is in commit 62757c32d5db ("tools: gpio: add multi-line monitoring to gpio-event-mon"). Before this commit the iterator 'i' in monitor_device() is used for counting of the events (loops). In the case of the above command (-c 1) we should start from 0 and increment 'i' only ones and hit the 'break' statement and exit the process. But after the above commit counting doesn't start from 0, it start from 1 when we listen on one line. It is because 'i' is used from one more purpose, counting of lines (num_lines) and it isn't restore to 0 after following code for (i = 0; i < num_lines; i++) gpiotools_set_bit(&values.mask, i); Restore the initial value of the iterator to 0 in order to allow counting of loops to work for any cases.

kbuild: replace $(if A,A,B) with $(or A,B)

2022-02-15T03:25:56+00:00

$(or ...) is available since GNU Make 3.81, and useful to shorten the code in some places. Covert as follows: $(if A,A,B) --> $(or A,B) This patch also converts: $(if A, A, B) --> $(or A, B) Strictly speaking, the latter is not an equivalent conversion because GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B) expands to " A", while $(or A, B) expands to "A". Anyway, preceding spaces are not significant in the code hunks I touched. Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier
