zephyr: Getting GPIOs from DTS file without aliases

Hiremath, Vijay P <vijay.p.hiremath@...>
 

Hi All,

 

I have a dts file for GPIO configs. I would like to know if it is possible to get the GPIOs without aliases

 

DTS file:

        pow_seq_gpio_keys {

                compatible = "gpio-keys";

            

EC_VR_EN_PP3300_A: GPIOA3 {

                        label = "EN_PP3300_A";

                        gpios = <&gpioa 3 GPIO_ACTIVE_HIGH>;

                };

        };

 

        aliases {

                pp3300aout = &EC_VR_EN_PP3300_A;

        };

 

C file:

Compiles:

        const struct device *pin_pp3300_en = device_get_binding(DT_GPIO_LABEL(DT_ALIAS(pp3300aout), gpios));

 

fails to compile:

        const struct device *pin_pp3300_en = device_get_binding(DT_GPIO_LABEL(EC_VR_EN_PP3300_A, gpios));

 

Regards

Vijay

2 questions about zephyrproject-rtos

szg10086@...
 

Hello,
Sorry to bother you that when I read the zephyrproject-rtos I had 2 questions.
In include/linker/linker-defs.h：117 there are some codes:

#define CREATE_OBJ_LEVEL(object, level)                         \
                __##object##_##level##_start = .;               \
                KEEP(*(SORT(.object##_##level[0-9]*)));         \
                KEEP(*(SORT(.object##_##level[1-9][0-9]*)));

It collects all these kinds of sections in order in linker script files.

The first question is what does the last '*' mean in the third line and fourth line. Does it mean the end or any kind of suffix?

The second question is whether there exists ambiguity in fourth line when level = 1, prio = 23 and when level = 12, prio = 3. Actually the maximum value of level is _SYS_INIT_LEVEL_SMP (equals 4 in init.h), however, I want to make sure about this question.

thank you.

Re: SMP support for RISC-V privilege architecture

Hi Katsuhiro,

That is actually a pretty good question.
The Risc-V arch port is currently in an "orphaned" state, as noted in MAINTAINERS.yaml.
The original contributors have not been heard from for some time.
Oh... I didn't check MAINTAINERS.yaml.


The project could really use someone to step up and take over maintainership of this arch.
Hmm... Can I help this issue?


I have also been frustrated by this, as there are some other recent contributions to enable user mode on Risc-V, but finding people to review the code, or help with some of the HW issues Alexandre is seeing when testing it, has been difficult.
Are you talking about this PR?
https://github.com/zephyrproject-rtos/zephyr/pull/27063

I have HiFive Unleashed (RV64 board) and buy a HiFive1 Rev.B (RV32 board).
Maybe I can get it in this week. After I receive it, I can help creating
board config for these boards and basic testing on RV32/RV64 real HW...

SMP support for RISC-V privilege architecture

Katsuhiro Suzuki
 

Hello,

Who is maintainer of RISC-V porting area?
I want to discuss about SMP support for RISC-V with maintainer(s).

Near a week ago, I posted SMP support for RISC-V and few days ago
Jim Shu from Andes Technology posted another version.

In such case what should I do for merging SMP support onto upstream?
Simply maintainers needs more days for reviewing both patch sets?
Or do I need to add more works (ex. unifying both patch set)?

Best Regards,
Katsuhiro Suzuki
introducing new delayable work API

Peter A. Bigot
 

I've been asked to request input on "kernel: workq: introduce delayable work" (#28891), which introduces a new API for supporting delayable work queue submission that cleans up some of the difficulty with correctly using the existing delayed work API.

"cleanup of work queue APIs and behavior" (#28579) (already merged) documented the problems with the existing API and states an intent that it be deprecated.  The problems with that API are not in dispute, only whether existing use in-tree meets the fairly strict requirements necessary for it to behave in a predictable matter.  For the cases I looked at it's not clear that they do.

The existing version of #28891 includes some deprecation commits intended as examples and verification.  These are intended as demonstration, and if there are concerns they don't meet the specific needs of those uses will be extracted and submitted as new PRs when the core functionality is integrated.

Please provide feedback on issue 28891 on github.

Peter

Dev-Review Meeting Agenda Oct 15

Kumar Gala
 

As we have no PRs currently tagged w/dev-review we don’t have a specific agenda this week.

Will see if there are any last minute PRs and if anyone has anything to discuss.

Depending on who joins we might continue discussion on pinmux.

Yes, we were planning on it but it's dropped off my radar since this initial
post.

The feedback I got from some developers (offline) was we need to get the powerpc
cross compilers working in zephyr-sdk-ng as a pre-requisite for this port to be
considered upstream. I did start work on that but never pushed it publicly.

Hi all,

Below is a basic port of Zephyr to powerpc:

https://github.com/mikey/zephyr/commits/powerpc

It runs on both qemu and and microwatt [1]. It runs the basic tests and samples
in the repository and supports both cooperative and pre-emptive multitasking.

The patch still contains a few FIXMEs but reviews are welcome. When we are
comfortable with the patch, we'd like to create a PR so it can be considered for
inclusion in the upstream project.

The port was done by Anton Blanchard and myself.

Mikey
