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/riscv64-linux/bin/riscv64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/riscv64-linux/bin/riscv64-linux-ld --version # < git log --format=%s --max-count=1 fca7526b7d8910c6125cb1ebc3e78ccd5f50ec52 # make -s -j 32 ARCH=riscv O=/kisskb/build/linus_rv32_defconfig_riscv-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/riscv64-linux/bin/riscv64-linux- rv32_defconfig Using .config as base Merging /kisskb/src/arch/riscv/configs/32-bit.config Value of CONFIG_PORTABLE is redefined by fragment /kisskb/src/arch/riscv/configs/32-bit.config: Previous value: CONFIG_PORTABLE=y New value: # CONFIG_PORTABLE is not set Value of CONFIG_NONPORTABLE is redefined by fragment /kisskb/src/arch/riscv/configs/32-bit.config: Previous value: # CONFIG_NONPORTABLE is not set New value: CONFIG_NONPORTABLE=y # # merged configuration written to .config (needs make) # .config:6309:warning: override: ARCH_RV32I changes choice state # < make -s -j 32 ARCH=riscv O=/kisskb/build/linus_rv32_defconfig_riscv-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/riscv64-linux/bin/riscv64-linux- help # make -s -j 32 ARCH=riscv O=/kisskb/build/linus_rv32_defconfig_riscv-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/riscv64-linux/bin/riscv64-linux- olddefconfig # make -s -j 32 ARCH=riscv O=/kisskb/build/linus_rv32_defconfig_riscv-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/riscv64-linux/bin/riscv64-linux- Completed OK # rm -rf /kisskb/build/linus_rv32_defconfig_riscv-gcc13 # Build took: 0:02:41.854072
