Steps: 1.enable qemu debug print, using simply scprit as below: grep "//#define DEBUG" * -rl | xargs sed -i "s/\/\/#define DEBUG/#define DEBUG/g" 2. make -j 3. get some warning: hw/i2c/pm_smbus.c: In function 'smb_ioport_writeb': hw/i2c/pm_smbus.c:142: warning: format '%04x' expects type 'unsigned int', but argument 2 has type 'hwaddr' hw/i2c/pm_smbus.c:142: warning: format '%02x' expects type 'unsigned int', but argument 3 has type 'uint64_t' hw/i2c/pm_smbus.c: In function 'smb_ioport_readb': hw/i2c/pm_smbus.c:209: warning: format '%04x' expects type 'unsigned int', but argument 2 has type 'hwaddr' hw/intc/i8259.c: In function 'pic_ioport_read': hw/intc/i8259.c:373: warning: format '%02x' expects type 'unsigned int', but argument 2 has type 'hwaddr' hw/input/pckbd.c: In function 'kbd_write_command': hw/input/pckbd.c:232: warning: format '%02x' expects type 'unsigned int', but argument 2 has type 'uint64_t' hw/input/pckbd.c: In function 'kbd_write_data': hw/input/pckbd.c:333: warning: format '%02x' expects type 'unsigned int', but argument 2 has type 'uint64_t' hw/isa/apm.c: In function 'apm_ioport_writeb': hw/isa/apm.c:44: warning: format '%x' expects type 'unsigned int', but argument 2 has type 'hwaddr' hw/isa/apm.c:44: warning: format '%02x' expects type 'unsigned int', but argument 3 has type 'uint64_t' hw/isa/apm.c: In function 'apm_ioport_readb': hw/isa/apm.c:67: warning: format '%x' expects type 'unsigned int', but argument 2 has type 'hwaddr' hw/timer/mc146818rtc.c: In function 'cmos_ioport_write': hw/timer/mc146818rtc.c:394: warning: format '%02x' expects type 'unsigned int', but argument 3 has type 'uint64_t' hw/i386/pc.c: In function 'port92_write': hw/i386/pc.c:479: warning: format '%02x' expects type 'unsigned int', but argument 2 has type 'uint64_t' Fix them.
