The current 'DEBUG_KVM' macro is defined in many files, and turning on the debug switch requires code modification, which is very inconvenient, so this series add an option to configure to support the definition of the 'DEBUG_KVM' macro. In addition, patches 3 and 4 also make printf always compile in debug output which will prevent bitrot of the format strings by referring to the commit(08564ecd: s390x/kvm: make printf always compile in debug output). alexchen (4): configure: Add a --enable-debug-kvm option to configure kvm: replace DEBUG_KVM to CONFIG_DEBUG_KVM kvm: make printf always compile in debug output i386/kvm: make printf always compile in debug output accel/kvm/kvm-all.c | 11 ++++------- configure | 10 ++++++++++ target/i386/kvm.c | 11 ++++------- target/mips/kvm.c | 6 ++++-- target/s390x/kvm.c | 6 +++--- 5 files changed, 25 insertions(+), 19 deletions(-) -- 2.19.1
