usage: qemu-sparc64 [options] program [arguments...] Linux CPU emulator (compiled for sparc64 emulation) Options and associated environment variables: Argument Env-variable Description -h print this help -help -g port QEMU_GDB wait gdb connection to 'port' -L path QEMU_LD_PREFIX set the elf interpreter prefix to 'path' -s size QEMU_STACK_SIZE set the stack size to 'size' bytes -cpu model QEMU_CPU select CPU (-cpu help for list) -E var=value QEMU_SET_ENV sets targets environment variable (see below) -U var QEMU_UNSET_ENV unsets targets environment variable (see below) -0 argv0 QEMU_ARGV0 forces target process argv[0] to be 'argv0' -r uname QEMU_UNAME set qemu uname release string to 'uname' -B address QEMU_GUEST_BASE set guest_base address to 'address' -R size QEMU_RESERVED_VA reserve 'size' bytes for guest virtual address space -d item[,...] QEMU_LOG enable logging of specified items (use '-d help' for a list of items) -D logfile QEMU_LOG_FILENAME write logs to 'logfile' (default stderr) -p pagesize QEMU_PAGESIZE set the host page size to 'pagesize' -singlestep QEMU_SINGLESTEP run in singlestep mode -strace QEMU_STRACE log system calls -seed QEMU_RAND_SEED Seed for pseudo-random number generator -trace QEMU_TRACE [[enable=]<pattern>][,events=<file>][,file=<file>] -version QEMU_VERSION display version information and exit Defaults: QEMU_LD_PREFIX = /etc/qemu-binfmt/sparc64 QEMU_STACK_SIZE = 8388608 byte You can use -E and -U options or the QEMU_SET_ENV and QEMU_UNSET_ENV environment variables to set and unset environment variables for the target process. It is possible to provide several variables by separating them by commas in getsubopt(3) style. Additionally it is possible to provide the -E and -U options multiple times. The following lines are equivalent: -E var1=val2 -E var2=val2 -U LD_PRELOAD -U LD_DEBUG -E var1=val2,var2=val2 -U LD_PRELOAD,LD_DEBUG QEMU_SET_ENV=var1=val2,var2=val2 QEMU_UNSET_ENV=LD_PRELOAD,LD_DEBUG Note that if you provide several changes to a single variable the last change will stay in effect.
