additional arm configs #21

Open nickdesaulniers opened 6 years ago

nickdesaulniers commented 6 years ago

@tom-gall might have some more board specific configs we want make sure continue to work.

I'm not sure if we want to get too wide with configs with travis, but maybe this is feasible?

nickdesaulniers commented 6 years ago

+ @agners who might have a recommended armv6 config?

nathanchance commented 6 years ago

If #20 works out, I don't think it should be too bad.

ast2500_g5_defconfig is an armv6 machine (I'm the maintainer for that platform, so I have an interest in seeing it tested).

It has a corresponding qemu machine -M romulus-bmc that we can boot.

nickdesaulniers commented 6 years ago

@shenki yeah, sounds good then. We'll need a buildroot image for it. Have you worked with buildroot before? (I should sit down an write a blog post about it, otherwise I'll soon forget how to do so myself).

multi_v5_defconfig should be small, and covers some of the older platforms.

vf610m4_defconfig or stm32_defconfig would be good examples for ARMv7-M, I'd suggest the former, since Stefan is familiar with that platform though the stm32 one is more common.

Adding a big-endian config would also be helpful, as we've had problems with that in the past.

@shenki I guess that is the machine you created issue https://github.com/ClangBuiltLinux/linux/issues/90 for?

I guess something with ARMv6 architecture might be interesting anyway. Also RPi1 is ARMv6. There is ARM11MPCore emulation in Qemu, e.g. realview-eb-mpcore kernel defconfig realview_defconfig.

@arndb yeah I do have hardware to boot vf610m4_defconfig, actually I can boot such a kernel using U-Boot from the Cortex-A core of that SoC. Would be a good candidate for Kernel CI ARMv7-M testing...

@agners yes, that's correct

I put up a change that changes the arm32 buildroot to build a generic image (arm926ej-s based, so ARMv5). This way we can share the image for all of the arm32 systems we want to test:
