pkg/gecko_sdk: Bump to version 4.1.2 #18739

jue89 · 2022-10-13T21:54:38Z

Contribution description

This PR updates the SDK to the latest release.

The update is required to bring back SiLabs' RAIL lib support to RIOT.

Testing procedure

I've run buildtests for all EFM32-based boards that are present in RIOT:

I noticed Kconfig stuff had to be adjusted. Maybe someone familiar wir Kconfig can have a look? (@MrKevinWeiss? ;-))

I'm unsure if I modeled Kconfig correctly:

PACKAGE_GECKO_SDK includes the modules MODULE_GECKO_SDK_EMLIB, MODULE_GECKO_SDK_EMLIB_EXTRA, MODULE_GECKO_SDK_LIBRAIL and MODULE_GECKO_SDK_LIBRAIL_PA
MODULE_GECKO_SDK_EMLIB, MODULE_GECKO_SDK_EMLIB_EXTRA have to pulled in if an EFM32 MCU is used. So there is no reason to pull in PACKAGE_GECKO_SDK without both modules. (Currently it just sets default y)
MODULE_GECKO_SDK_LIBRAIL and MODULE_GECKO_SDK_LIBRAIL_PA are optional and can be required individually.

jue89 · 2022-10-14T12:42:48Z

And another Kconfig problem: gecko_sdk_librail is shipped with compiled blobs. For some EFR32 MCUs they are compiled with soft-float even though the MCU has an FPU inside! Thus, I had to opt-out the module cortexm_fpu. This works perfectly with the Makefile-based dependency resolution. But how do I model this using the Kconfig system?

The module is modeled like this:

config MODULE_CORTEXM_FPU
    bool "Cortex-M Floating Point Unit (FPU) support"
    default y
    depends on HAS_CORTEXM_FPU

jue89 · 2022-10-15T12:07:11Z

After sleeping over this problem, I tried to model this FPU vs. non-FPU librail as features.

(TBH: This was advertisement for the Kconfig system. This was easy to model compared to the Makefile-based approach ...)

maribu

Looks good to me.

I think that the non-FPU version of librail should run without any issues even with an FPU. Maybe it is only the wording that needs updating (e.g. something along the lines "Yes, you could use the non-FPU version, but since you have an FPU you really do not want to bloat up your firmware with a soft-FPU implementation. So go use the FPU version instead!")?

cpu/efm32/Makefile.features

@@ -22,6 +25,9 @@ FEATURES_PROVIDED += periph_wdt

That's surprising to me. It is obvious that a library that expects a FPU won't function without it, but a lib not expecting an FPU could just not use it, even if it is present.

Well, I can't link if cortexm_fpu is enabled. I really don't know if any floats are used in that blob, but the .ASM.attributes section in the object indicates that it has been built with soft floats and, thus, the linker complains about that. That's at least what I'm observing here.

Those are the linker errors if I'm building `ikea-tradfri` with `gecko_sdk_librail` and `cortexm_fpu`

OK, sounds like the calling convention is different when not using an FPU. Likely only for passing floats, but since librail actually does use floats this could indeed be a real issue.

I really should read the calling convention specs at some point in time to not be surprised by these things.

pkg/gecko_sdk/Kconfig

+        Indicates that the CPU offers librail support if the FPU is enabled.
+        Librail is shipped as pre-compiled blobs. Thus, we have to adapt to
+        their choice how to process floats.


So RAIL is the radio HAL, right? They use floats in their radio driver?!?

I've seen many surprising design choices made by Silabs ... but yes, I wouldn't expect a radio HAL using floats, as well :D But I can't tell - that's the problem with those vendor-specific blobs. Actually, I spent way too long with the integration because of those black boxes. And they weren't willing to let me look inside even after dozes of exchanged emails :/
