# 2) "vm%pid" (for PPC Book3s HV KVM); # 3) "vm%u_vcpu%u_timing" (for PPC Book3e KVM). # # The problem with this is that multiple VMs per process is not allowed for # 2) and 3) which makes it possible for userspace to trigger errors when # creating duplicated debugfs entries. # # This merges all these into 1). # # This defines kvm_arch_create_kvm_debugfs() similar to # kvm_arch_create_vcpu_debugfs(). # # This defines 2 hooks in kvmppc_ops that allow specific KVM implementations # add necessary entries, this adds the _e500 suffix to # kvmppc_create_vcpu_debugfs_e500() to make it clear what platform it is for. # # This makes use of already existing kvm_arch_create_vcpu_debugfs() on PPC. # # This removes no more used debugfs_dir pointers from PPC kvm_arch structs. # # This stops removing vcpu entries as once created vcpus stay around # for the entire life of a VM and removed when the KVM instance is closed, # see d56f5136b010 ("KVM: let kvm_destroy_vm_debugfs clean up vCPU # debugfs directories". # # Suggested-by: Fabiano Rosas <farosas@linux.ibm.com> # Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> # --- # Changes: # v3: # * reworked commit log, especially, the bit about removing vcpus # # v2: # * handled powerpc-booke # * s/kvm/vm/ in arch hooks # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 c83c7a55453f822f602332d22328a288f281ff59 # < make -s -j 24 ARCH=x86 O=/kisskb/build/aik_x86-allmodconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 24 ARCH=x86 O=/kisskb/build/aik_x86-allmodconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 24 ARCH=x86 O=/kisskb/build/aik_x86-allmodconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 24 ARCH=x86 O=/kisskb/build/aik_x86-allmodconfig_x86_64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/x86_64-linux/bin/x86_64-linux- vmlinux.o: warning: objtool: __do_fast_syscall_32()+0xa: call to stackleak_track_stack() leaves .noinstr.text section vmlinux.o: warning: objtool: do_syscall_64()+0x9: call to stackleak_track_stack() leaves .noinstr.text section vmlinux.o: warning: objtool: do_int80_syscall_32()+0x9: call to stackleak_track_stack() leaves .noinstr.text section vmlinux.o: warning: objtool: xen_get_debugreg()+0xb: call to HYPERVISOR_get_debugreg() leaves .noinstr.text section vmlinux.o: warning: objtool: xen_set_debugreg()+0x15: call to HYPERVISOR_set_debugreg.isra.0() leaves .noinstr.text section vmlinux.o: warning: objtool: exc_general_protection()+0x22: call to stackleak_track_stack() leaves .noinstr.text section vmlinux.o: warning: objtool: fixup_bad_iret()+0x20: call to stackleak_track_stack() leaves .noinstr.text section vmlinux.o: warning: objtool: mce_setup()+0x18: call to memset() leaves .noinstr.text section vmlinux.o: warning: objtool: do_machine_check()+0x27: call to stackleak_track_stack() leaves .noinstr.text section vmlinux.o: warning: objtool: .entry.text+0x10e6: call to stackleak_erase() leaves .noinstr.text section vmlinux.o: warning: objtool: .entry.text+0x143: call to stackleak_erase() leaves .noinstr.text section vmlinux.o: warning: objtool: .entry.text+0x17d9: call to stackleak_erase() leaves .noinstr.text section Completed OK # rm -rf /kisskb/build/aik_x86-allmodconfig_x86_64-gcc11 # Build took: 0:42:35.567004
