Cross-compiling on a x86 box works nicely. First I thought it's a problem with setting the "cross_compiling" flag in ./Makefile. But that's not sufficient. On a x86 machine (which builds fine) I get SRCARCH=parisc SUBARCH=x86 UTS_MACHINE=parisc The arch/parisc/kernel/asm-offsets.c file gets preprocessed via: hppa64-linux-gnu-gcc On a native 32bit parisc machine I have: SRCARCH=parisc SUBARCH=parisc UTS_MACHINE=parisc Here the arch/parisc/kernel/asm-offsets.c file gets preprocessed via: gcc Instead here the native hppa64-linux-gnu-gcc (cross compiler) should have been used too, since we build a 64-bit hppa kernel (CONFIG_64BIT is set). Note, on hppa we don't have an "-m64" compiler flag as on x86. Mashahiro, do you maybe have an idea what gets wrong here, or which patch has changed the behaviour how the asm-offsets.c file gets preprocessed?

Presumably, commit 23243c1ace9fb4eae2f75e0fe0ece8e3219fb4f3 Prior to that commit, arch/parisc/Makefile was like this: ifneq ($(SUBARCH),$(UTS_MACHINE)) ifeq ($(CROSS_COMPILE),) ... Now I understand why arch/parisc/Makefile was written this way. Reverting the change in arch/parisc/Makefile will restore the original behavior. But, please keep in mind that there is an issue remaining. Please see this code: ifdef CONFIG_64BIT UTS_MACHINE := parisc64 CHECKFLAGS += -D__LP64__=1 CC_ARCHES = hppa64 LD_BFD := elf64-hppa-linux else # 32-bit CC_ARCHES = hppa hppa2.0 hppa1.1 LD_BFD := elf32-hppa-linux endif UTS_MACHINE is determined by CONFIG_64BIT. CONFIG_64BIT is defined only after Kconfig is finished. When you are trying to configure the .config, CONFIG_64BIT is not defined yet. So UTS_MACHINE is always 'parisc'. As you know, Kconfig files now have a bunch of 'cc-option' syntax to check the compiler capability in Kconfig time. Hence, you need to provide a proper compiler in Kconfig time too. When you build a 64-bit parisc kernel on a 32-bit parisc machine, Kconfig is passed with CC=gcc since SUBARCH==UTS_MACHINE==parisc. After Kconfig, CROSS_COMPILE=hppa64-* is set, and the kernel is built by CC=hppa64-*-gcc. So, Kconfig evaluated a compiletely different compiler. This is pointless. There are some options [option 1] revert the parisc bit of 23243c1ace9fb4eae2f75e0fe0ece8e3219fb4f3 This will restore the functionality you may want, but as I said above, Kconfig is doing pointless things. [option 2] Stop using cc-cross-prefix, and pass CROSS_COMPILE explicitly. This is what many architectures including arm, arm64 do. You need to explicitly pass CROSS_COMPILE=aarch64-linux-gnu- etc. if you are cross-compiling arm64. [option 3] Introduce ARCH=parisc64. When you are building 64-bit kernel, you can pass ARCH=parisc64 A patch attached.

Is there a way to do $ make ARCH=parisc64 allmodconfig ? That does not set CONFIG_64BIT in my testing. (testing on linux-next-20220817) I would like to have a command-line method to do that, without editing the .config file. Thanks. -- ~Randy ^ permalink raw reply [flat|nested] 14+ messages in thread

I found your patch for riscv: https://lore.kernel.org/all/20210912034538.19404-1-rdunlap@infradead.org/ and added a similiar one for parisc into my for-next git tree: https://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git/commit/?h=for-next&id=34793a5d09d9122f90acfa7e8f705436d5090d4d Does that help? Although, I'd prefer a generic solution for this problem, e.g. a new KCONFIG_MIN_RAND_CONFIG=$(srctree)/arch/parisc/configs/32-bit.config option which is used by randconfig/allmodconfig/.... Then it could be set once, and we can get rid of adding similiar patches to the arches, e.g. in arch/parisc/Makefile it could be: ifeq ($(ARCH),parisc64) KBUILD_DEFCONFIG := generic-64bit_defconfig KCONFIG_MIN_RAND_CONFIG = $(srctree)/arch/parisc/configs/64-bit.config else KBUILD_DEFCONFIG := generic-32bit_defconfig KCONFIG_MIN_RAND_CONFIG = $(srctree)/arch/parisc/configs/32-bit.config endif Thoughts?

I think it is the same as before. Is this thread related? The reason is 64BIT depends on PA8X00. allmodconfig chooses PA7000 instead of PA8X00 in the "Processor type" choice since PA7000 is the default.

That patch "partly" works, in the sense that with: make ARCH=parisc64 randconfig you randomly end up with a 32- or 64-bit kernel. Since "ARCH=parisc64" was given, one probably would expect a 64-bit-enabled kernel randconfig, and with "ARCH=parisc" a 32-bit randconfig. But, I'm not sure if this intended or not and works that way on other arches as well. As written in the other mail, I added this patch in for-next: https://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git/commit/?h=for-next&id=34793a5d09d9122f90acfa7e8f705436d5090d4d The downside is, you need to give a special make target: parisc_randconfig / parisc64_randconfig Helge ^ permalink raw reply [flat|nested] 14+ messages in thread

Ah, OK. Then, you can mimic sparc code. In the top Makefile: ifeq ($(ARCH),sparc32) SRCARCH := sparc endif ifeq ($(ARCH),sparc64) SRCARCH := sparc endif In arch/sparc/Kconfig: config 64BIT bool "64-bit kernel" if "$(ARCH)" = "sparc" default "$(ARCH)" = "sparc64" "make ARCH=sparc32 randconfig" always disables CONFIG_64BIT, and randomizes the rest of options. "make ARCH=sparc64 randconfig" always enables CONFIG_64BIT, and randomizes the rest of options. "make ARCH=sparc randconfig" randomizes all options, including CONFIG_64BIT.

Ah, cool. Thank you! > I suggest to introduce ARCH=parisc32 No need. We already have ARCH=parisc64 or ARCH=parisc. The patch below fixes it nicely and I've pushed it into the parisc for-next git tree. @Randy: Maybe you could try it as well. With that approach you get what you want. Maybe that's a better approach for riscv64 as well?

This means, the ARCH= parameter will give: ARCH=parisc -> 32-bit kernel ARCH=parisc64 -> 64-bit kernel This simplifies the usage of the other config options like randconfig, allmodconfig and allyesconfig a lot and produces the output which is expected for parisc64 (64-bit) vs. parisc (32-bit).
