6e65886fceb23605eff952d6b1975737b4c4b154 - selftests/powerpc: Suppress -Wmaybe-uninitialized with GCC 15

Fri, 13 Mar 2026 17:54:26 +0100

selftests/powerpc: Suppress -Wmaybe-uninitialized with GCC 15GCC 15 reports the below false positive '-Wmaybe-uninitialized' warningin vphn_unpack_associativity() when building the powerpc selftests. # make -C tools/testing/selftests TARGETS="powerpc" [...] CC test-vphn In file included from test-vphn.c:3: In function ‘vphn_unpack_associativity’, inlined from ‘test_one’ at test-vphn.c:371:2, inlined from ‘test_vphn’ at test-vphn.c:399:9: test-vphn.c:10:33: error: ‘be_packed’ may be used uninitialized [-Werror=maybe-uninitialized] 10 | #define be16_to_cpup(x) bswap_16(*x) | ^~~~~~~~ vphn.c:42:27: note: in expansion of macro ‘be16_to_cpup’ 42 | u16 new = be16_to_cpup(field++); | ^~~~~~~~~~~~ In file included from test-vphn.c:19: vphn.c: In function ‘test_vphn’: vphn.c:27:16: note: ‘be_packed’ declared here 27 | __be64 be_packed[VPHN_REGISTER_COUNT]; | ^~~~~~~~~ cc1: all warnings being treated as errorsWhen vphn_unpack_associativity() is called from hcall_vphn() in kernelthe error is not seen while building vphn.c during kernel compilation.This is because the top level Makefile includes '-fno-strict-aliasing'flag always.The issue here is that GCC 15 emits '-Wmaybe-uninitialized' due to typepunning between __be64[] and __b16* when accessing the buffer viabe16_to_cpup(). The underlying object is fully initialized but GCC 15fails to track the aliasing due to the strict aliasing violation here.Please refer [1] and [2]. This results in a false positive warning whichis promoted to an error under '-Werror'. This problem is not seen whenthe compilation is performed with GCC 13 and 14. An issue [1] has alsobeen created on GCC bugzilla.The selftest compiles fine with '-fno-strict-aliasing'. Since this GCCflag is used to compile vphn.c in kernel too, the same flag should beused to build vphn tests when compiling vphn.c in the selftest as well.Fix this by including '-fno-strict-aliasing' during vphn.c compilationin the selftest. This keeps the build working while limiting the scopeof the suppression to building vphn tests.[1] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=124427[2] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99768Fixes: 58dae82843f5 ("selftests/powerpc: Add test for VPHN")Reviewed-by: Vaibhav Jain Signed-off-by: Amit Machhiwal Tested-by: Venkat Rao Bagalkote Signed-off-by: Madhavan Srinivasan Link: https://patch.msgid.link/20260313165426.43259-1-amachhiw@linux.ibm.com List of files: /linux/tools/testing/selftests/powerpc/vphn/Makefile

Merge tag 'powerpc-6.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linuxPull powerpc updates from Michael Ellerman: - Enable BPF Kernel Functions (kfuncs) in the powerpc BPF JIT. - Allow per-process DEXCR (Dynamic Execution Control Register) settings via prctl, notably NPHIE which controls hashst/hashchk for ROP protection. - Install powerpc selftests in sub-directories. Note this changes the way run_kselftest.sh needs to be invoked for powerpc selftests. - Change fadump (Firmware Assisted Dump) to better handle memory add/remove. - Add support for passing additional parameters to the fadump kernel. - Add support for updating the kdump image on CPU/memory add/remove events. - Other small features, cleanups and fixes.Thanks to Andrew Donnellan, Andy Shevchenko, Aneesh Kumar K.V, ArndBergmann, Benjamin Gray, Bjorn Helgaas, Christian Zigotzky, ChristopheJaillet, Christophe Leroy, Colin Ian King, Cédric Le Goater, Dr. DavidAlan Gilbert, Erhard Furtner, Frank Li, GUO Zihua, Ganesh Goudar, GeoffLevand, Ghanshyam Agrawal, Greg Kurz, Hari Bathini, Joel Stanley, JustinStitt, Kunwu Chan, Li Yang, Lidong Zhong, Madhavan Srinivasan, MaheshSalgaonkar, Masahiro Yamada, Matthias Schiffer, Naresh Kamboju, NathanChancellor, Nathan Lynch, Naveen N Rao, Nicholas Miehlbradt, Ran Wang,Randy Dunlap, Ritesh Harjani, Sachin Sant, Shirisha Ganta, ShrikanthHegde, Sourabh Jain, Stephen Rothwell, sundar, Thorsten Blum, VaibhavJain, Xiaowei Bao, Yang Li, and Zhao Chenhui.* tag 'powerpc-6.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: (85 commits) powerpc/fadump: Fix section mismatch warning powerpc/85xx: fix compile error without CONFIG_CRASH_DUMP powerpc/fadump: update documentation about bootargs_append powerpc/fadump: pass additional parameters when fadump is active powerpc/fadump: setup additional parameters for dump capture kernel powerpc/pseries/fadump: add support for multiple boot memory regions selftests/powerpc/dexcr: Fix spelling mistake "predicition" -> "prediction" KVM: PPC: Book3S HV nestedv2: Fix an error handling path in gs_msg_ops_kvmhv_nestedv2_config_fill_info() KVM: PPC: Fix documentation for ppc mmu caps KVM: PPC: code cleanup for kvmppc_book3s_irqprio_deliver KVM: PPC: Book3S HV nestedv2: Cancel pending DEC exception powerpc/xmon: Check cpu id in commands "c#", "dp#" and "dx#" powerpc/code-patching: Use dedicated memory routines for patching powerpc/code-patching: Test patch_instructions() during boot powerpc64/kasan: Pass virtual addresses to kasan_init_phys_region() powerpc: rename SPRN_HID2 define to SPRN_HID2_750FX powerpc: Fix typos powerpc/eeh: Fix spelling of the word "auxillary" and update comment macintosh/ams: Fix unused variable warning powerpc/Makefile: Remove bits related to the previous use of -mcmodel=large ...
