2023-12-12tools/nolibc: mips: add support for PICThomas Weißschuh1-1/+1
MIPS requires some extra instructions to set up the $gp register for the with a pointer to the global data area. This isn't needed for non-PIC builds, but this patch enables the code unconditionally to prevent bitrot. Also enable PIC in one of the test configurations for ongoing validation.

2023-12-12selftests/nolibc: support out-of-tree buildsThomas Weißschuh1-4/+14
Out of tree builds are much more convenient when building for multiple architectures or configurations in parallel. Only absolute O= parameters are supported as Makefile.include will always resolve relative paths in relation to $(srctree) instead of the current directory. Add a call to "make outputmakefile" to verify that the sourcetree is clean. This is based on Zhangjins out-of-tree patch. It extends that work for get_init_cpio support and also drops relative O= specifications explicitly.

While users most likely don't have the LoongArch EFI binary installed at least an explicit error about 'file not found' is better than a hanging test without output that can never succeed.

2023-10-12selftests/nolibc: don't embed initramfs into kernel imageThomas Weißschuh1-16/+26
When the initramfs is embedded into the kernel each rebuild of it will trigger a full kernel relink and all the expensive postprocessing steps. Currently nolibc-test and therefore the initramfs are always rebuild, even without source changes, leading to lots of slow kernel relinks. Instead of linking the initramfs into the kernel assemble it manually and pass it explicitly to qemu. This avoids all of the kernel relinks.

2023-08-23selftests/nolibc: add test support for ppc64Zhangjin Wu1-0/+6
Kernel uses ARCH=powerpc for both 32-bit and 64-bit PowerPC, here adds a ppc64 variant for big endian 64-bit PowerPC, users can pass XARCH=ppc64 to test it. The powernv machine of qemu-system-ppc64 is used with powernv_be_defconfig. As the document [1] shows: PowerNV (as Non-Virtualized) is the “bare metal” platform using the OPAL firmware. It runs Linux on IBM and OpenPOWER systems and it can be used as an hypervisor OS, running KVM guests, or simply as a host OS. Notes, - differs from little endian 64-bit PowerPC, vmlinux is used instead of zImage, because big endian zImage [2] only boot on qemu with x-vof=on (added from qemu v7.0) and a fixup patch [3] for qemu v7.0.51: - since the VSX support may be disabled in kernel side, to avoid "illegal instruction" errors due to missing VSX kernel support, let's simply let compiler not generate vector/scalar (VSX) instructions via the '-mno-vsx' option. - as 'man gcc' shows, '-mmultiple' is used to generate code that uses the load multiple word instructions and the store multiple word instructions. Those instructions do not work when the processor is in little-endian mode (except PPC740/PPC750), so, we only enable it for big endian powerpc. - for big endian ppc64, as the help message from arch/powerpc/Kconfig shows, the V2 ABI is standard for 64-bit little-endian, but for big-endian it is less well tested by kernel and toolchain, so, use elfv1 as-is, no need to explicitly ask toolchain to use elfv2 here.

Kernel uses ARCH=powerpc for both 32-bit and 64-bit PowerPC, here adds a ppc variant for 32-bit PowerPC and uses it as the default variant of powerpc architecture. Users can pass XARCH=ppc (or ARCH=powerpc) to test 32-bit PowerPC. The default qemu-system-ppc g3beige machine [1] is used to run 32-bit powerpc kernel with pmac32_defconfig. The missing PMACZILOG serial tty and console are enabled in another patch [2]. Note, - zImage doesn't boot due to "qemu-system-ppc: Some ROM regions are overlapping" error, so, vmlinux is used instead. - since the VSX support may be disabled in kernel side, to avoid "illegal instruction" errors due to missing VSX kernel support, let's simply let compiler not generate vector/scalar (VSX) instructions via the '-mno-vsx' option. - as 'man gcc' shows, '-mmultiple' is used to generate code that uses the load multiple word instructions and the store multiple word instructions.

2023-08-23selftests/nolibc: add XARCH and ARCH mapping supportZhangjin Wu1-12/+34
Most of the CPU architectures have different variants, but kernel usually only accepts parts of them via the ARCH variable, the others should be customized via kernel config files. To simplify testing, a new XARCH variable is added to extend the kernel's ARCH with a few variants of the same architecture, and it is used to customize variant specific variables, at last XARCH is converted to the kernel's ARCH: e.g. make run XARCH=<one of the supported variants> | \ | `-> variant specific variables: | IMAGE, DEFCONFIG, QEMU_ARCH, QEMU_ARGS, CFLAGS ... \ `---> kernel's ARCH XARCH and ARCH are carefully mapped to allow users to pass architecture variants via XARCH or pass architecture via ARCH from cmdline. PowerPC is the first user and also a very good reference architecture of this mapping, it has variants with different combinations of 32-bit/64-bit and bit endian/little endian. To use this mapping, the other architectures can refer to PowerPC, If the target architecture only has one variant, XARCH is simply an alias of ARCH, no additional mapping required.

2023-03-28tools/nolibc: tests: fold in no-stack-protector cflagsThomas Weißschuh1-2/+3
For the cflags to enable stack protectors to work properly they need to be specified after -fno-stack-protector. To do this fold all cflags into a single variable and move -fno-stack-protector before the arch-specific cflags and another one specific to stack protectors since we don't want to enable them on all archs.
