2011-06-15Command line support for altering the log file locationMatthew Fernandez1-17/+26
Add command line support for logging to a location other than /tmp/qemu.log. With logging enabled (command line option -d), the log is written to the hard-coded path /tmp/qemu.log. This patch adds support for writing the log to a different location by passing the -D option.

2011-05-31target-alpha: Tidy exception constants.Richard Henderson1-30/+14
There's no need to attempt to match EXCP_* values with PALcode entry point offsets. Instead, compress all the values to make for more efficient switch statements within QEMU. We will be doing TLB fill within QEMU proper, not within the PALcode, so all of the ITB/DTB miss, double fault, and access exceptions can be compressed to EXCP_MMFAULT. Compress all of the EXCP_CALL_PAL exceptions into one. Use env->error_code to store the specific entry point. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Rationalize internal processor registers.Richard Henderson1-3/+3

Quite a number of uid/gid related syscalls are only defined on systems with USE_UID16 defined. This is apperently based on the idea that these system calls would never be called on non-UID16 systems. Make these syscalls available for all architectures that define them. drop alpha hack to support selected UID16 syscalls.

2011-03-06linux-user: Fix large seeks by 32 bit guest on 64 bit hostPeter Maydell1-6/+10
When emulating a 32 bit Linux user-mode program on a 64 bit target we implement the llseek syscall in terms of lseek. Correct a bug which meant we were silently casting the result of host lseek() to a 32 bit integer as it passed through get_errno() and thus throwing away the top half. We also don't try to store the result back to userspace unless the seek succeeded; this matches the kernel behaviour. Thanks to Eoghan Sherry for identifying the problem and suggesting a solution.
