2013-07-09log: Change log_cpu_state[_mask]() argument to CPUStateAndreas Färber1-2/+3
Since commit 878096eeb278a8ac1ccd6667af73e026f29b4cf5 (cpu: Turn cpu_dump_{state,statistics}() into CPUState hooks) CPUArchState is no longer needed. Add documentation and make the functions available through qemu/log.h outside NEED_CPU_H to allow use in qom/cpu.c. Moving them to qom/cpu.h was not yet possible due to convoluted include paths, so that some devices grow an implicit and unneeded dependency on qom/cpu.h for now.

2013-07-05linux-user: improve target_to_host_sock_type conversionPetar Jovanovic2-149/+275
Previous implementation has failed to take into account different value of SOCK_NONBLOCK on target and host, and existence of SOCK_CLOEXEC. The same conversion has to be applied both for do_socket and do_socketpair, so the code has been isolated in a static inline function. enum sock_type in linux-user/socket.h has been extended to include TARGET_SOCK_CLOEXEC and TARGET_SOCK_NONBLOCK, similar to definition in libc. The patch also includes necessary code style changes (tab to spaces) in the header file since most of the file has been touched by this change.

2013-07-05linux-user: Fix sys_utimensat (would not compile on old glibc)Peter Maydell1-4/+12
Commit c0d472b12e accidentally dropped the definition of __NR_SYS_utimensat even though its use is guarded by CONFIG_UTIMENSAT, not CONFIG_ATFILE. Some older glibc don't have utimensat() (even if they have the other *at() functions). Fix this by correctly cleaning up the sys_utimensat() implementation and #defines, so that we always provide the syscall if needed whether we're doing it via glibc or not.

2013-06-12linux-user: Drop direct use of openat etc syscallsPeter Maydell1-194/+24
The linux-user syscall emulation layer currently supports the openat family of syscalls via two mechanisms: simply calling the corresponding libc functions, and making direct syscalls. Since glibc has supported these functions since at least glibc 2.5, there's no real need to retain the (essentially untested) direct syscall fallback code, so simply delete it. This allows us to remove some ifdeffery that was attempting to disable provision of some of the syscalls if the host didn't seem to support them, which in some cases was actually wrong (eg where there are several flavours of the syscall and we only need one of them, not necessarily the exact one the guest has, as with the fstatat* calls).

2013-05-20linux-user: Save the correct resume address for MIPS signal handlingKwok Cheung Yeung1-1/+2
The current ISA mode needs to be saved in bit 0 of the resume address. If the current instruction happens to be in a branch delay slot, then the address of the preceding jump instruction should be stored instead. exception_resume_pc already does both of these tasks, so it is made available and reused. MIPS_HFLAG_BMASK in hflags is cleared, otherwise QEMU may treat the first instruction of the signal handler as a delay slot instruction.

Processors supporting the MIPS16 or microMIPS ISAs set bit 0 in target addresses to indicate that the target is written using a compressed ISA. During signal handling, when jumping to or returning from a signal handler, bit 0 of the destination PC is inspected and MIPS_HFLAG_M16 in hflags cleared or set accordingly. Bit 0 of the PC is then cleared. Signed-off-by: Kwok Cheung Yeung <kcy@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2013-03-11linux-user: Fix layout of usage table to account for option textPeter Maydell1-8/+16
The linux-user usage message attempts to line up the columns in its table by calculating the maximum width of any item in them. However for the 'Argument' column it was only accounting for the length of the option switch (eg "-d"), not the additional example text (eg "item[,...]"). This currently has no adverse effects because the widest item in the column happens to be the argumentless "-singlestep" option, but improving the "-d" option help to read "-d item[,...]" exceeds that limit. Fix this by correctly calculating maxarglen as the width of the first column text including a possible option argument, and adjusting its uses to match.
