Yes, the arguments to # drm_buddy_init() and drm_buddy_alloc_blocks() are in fact of type 'u64', # but none of the values here are remotely relevant, and the compiler will # happily just do the type expansion. # # Of course, in a perfect world the compiler would also have just noticed # that all the values in question are tiny, and range analysis would have # shown that doing a 64-bit divide is pointless, but that is admittedly # expecting a fair amount of the compiler. # # IOW, we shouldn't write code that the compiler then has to notice is # unnecessarily complicated just to avoid extra work. We do have fairly # high expectations of compilers, but kernel code should be reasonable to # begin with. # # It turns out that there are also other issues with this code: the KUnit # assertion messages have incorrect types in the format strings, but # that's a widely spread issue caused by the KUnit infrastructure not # having enabled format string verification. We'll get that sorted out # separately. # # Reported-by: Guenter Roeck <linux@roeck-us.net> # Fixes: a64056bb5a32 ("drm/tests/drm_buddy: add alloc_contiguous test") # Link: https://lore.kernel.org/all/538327ff-8d34-41d5-a9ae-1a334744f5ae@roeck-us.net/ # Cc: Matthew Auld <matthew.auld@intel.com> # Cc: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com> # Cc: Christian König <christian.koenig@amd.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 fca7526b7d8910c6125cb1ebc3e78ccd5f50ec52 # make -s -j 32 ARCH=sparc O=/kisskb/build/linus_allmodconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_64BIT=n # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 32 ARCH=sparc O=/kisskb/build/linus_allmodconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- help # make -s -j 32 ARCH=sparc O=/kisskb/build/linus_allmodconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- olddefconfig # make -s -j 32 ARCH=sparc O=/kisskb/build/linus_allmodconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- <stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sparc/lib/cmpdi2.c:6:11: error: no previous prototype for '__cmpdi2' [-Werror=missing-prototypes] 6 \| word_type __cmpdi2(long long a, long long b) \| ^~~~~~~~ cc1: all warnings being treated as errors make[4]: * [/kisskb/src/scripts/Makefile.build:243: arch/sparc/lib/cmpdi2.o] Error 1 make[3]: * [/kisskb/src/scripts/Makefile.build:481: arch/sparc/lib] Error 2 make[3]: * Waiting for unfinished jobs.... /kisskb/src/kernel/dma.c:70:5: error: no previous prototype for 'request_dma' [-Werror=missing-prototypes] 70 \| int request_dma(unsigned int dmanr, const char * device_id) \| ^~~~~~~~~~~ /kisskb/src/kernel/dma.c:88:6: error: no previous prototype for 'free_dma' [-Werror=missing-prototypes] 88 \| void free_dma(unsigned int dmanr) \| ^~~~~~~~ cc1: all warnings being treated as errors make[4]: * [/kisskb/src/scripts/Makefile.build:243: kernel/dma.o] Error 1 make[3]: * [/kisskb/src/scripts/Makefile.build:481: kernel] Error 2 /kisskb/src/drivers/mtd/maps/sun_uflash.c:50:5: error: no previous prototype for 'uflash_devinit' [-Werror=missing-prototypes] 50 \| int uflash_devinit(struct platform_device op, struct device_node dp) \| ^~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[6]: * [/kisskb/src/scripts/Makefile.build:243: drivers/mtd/maps/sun_uflash.o] Error 1 make[5]: * [/kisskb/src/scripts/Makefile.build:481: drivers/mtd/maps] Error 2 make[4]: * [/kisskb/src/scripts/Makefile.build:481: drivers/mtd] Error 2 make[4]: * Waiting for unfinished jobs.... make[3]: * [/kisskb/src/scripts/Makefile.build:481: drivers] Error 2 make[2]: * [/kisskb/src/Makefile:1921: .] Error 2 make[1]: * [/kisskb/src/Makefile:240: __sub-make] Error 2 make: * [Makefile:240: __sub-make] Error 2 Command 'make -s -j 32 ARCH=sparc O=/kisskb/build/linus_allmodconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- ' returned non-zero exit status 2. # rm -rf /kisskb/build/linus_allmodconfig_sparc64-gcc13 # Build took: 0:12:40.372157
