2015-01-27linux-user/alpha: Add define for NR_shmat to enable shmat syscallPeter Maydell
For historical reasons, the define for the shmat() syscall on Alpha is NR_osf_shmat; however it has the same semantics as this syscall does on all other architectures, so define TARGET_NR_shmat as well so that QEMU's code for the syscall is enabled. This patch brings our behaviour on the LTP shmat tests into line with that for ARM (still not a perfect pass rate but not "this syscall is completely broken" as we had before). (Problem detected via a clang warning that the do_shmat() function was unused on Alpha.)

2014-08-22linux-user: Support target-to-host translation of mlockall argumentTom Musta
The argument to the mlockall system call is not necessarily the same on all platforms and thus may require translation prior to passing to the host. For example, PowerPC 64 bit platforms define values for MCL_CURRENT (0x2000) and MCL_FUTURE (0x4000) which are different from Intel platforms (0x1 and 0x2, respectively) Signed-off-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

2014-03-10linux-user: set minimum kernel version to 2.6.32Riku Voipio
Popular glibc based distributions[1] require minimum 2.6.32 as kernel version. For some targets 2.6.18 would be enough, but dropping so low would mean some suboptimal system calls could get used. Set the minimum kernel advertized to 2.6.32 for all architectures but aarch64 to ensure working qemu linux-user in case host kernel is older.

2013-09-24alpha-linux-user: Fix umount syscall numbersRichard Henderson
It has been pointed out on LKML that the alpha umount syscall numbers are named wrong, and a patch to rectify that has been posted for 3.11. Glibc works around this by treating NR_umount as NR_umount2 if NR_oldumount exists. That's more complicated than we need in QEMU, given that we control linux-user/*/syscall_nr.h. This is the last instance of TARGET_NR_oldumount, so delete that from the strace.list. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
2013-07-09linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-userPeter Maydell
The functions cpu_clone_regs() and cpu_set_tls() are not purely CPU related -- they are specific to the TLS ABI for a a particular OS. Move them into the linux-user/ tree where they belong. target-lm32 had entirely unused implementations, since it has no linux-user target; just drop them.

2011-04-26linux-user: untie syscalls from UID16Riku Voipio
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. MIPS and PowerPC were also defined as UID16, to get uid/gid syscalls available, drop this error as well. Change QEMU to reflect this.

2009-12-13target-alpha: Fixes for alpha-linux syscalls.Richard Henderson
1. Add correct definitions of error numbers. 2. Implement SYS_osf_sigprocmask 3. Implement SYS_osf_get/setsysinfo for IEEE_FP_CONTROL. This last requires exposing the FPCR value to do_syscall. Since this value is actually split up into the float_status, expose routines from helper.c to access it. Finally, also add a float_exception_mask field to float_status. We don't actually use it to control delivery of exceptions to the emulator yet, but simply hold the value that we placed there when loading/storing the FPCR.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.
