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>
2014-08-22linux-user: Minimum Sig Handler Stack Size for PPC64 ELF V2Tom Musta
The ELF V2 ABI for PPC64 defines MINSIGSTKSZ as 4096 bytes whereas it was 2048 previously. 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.

2013-11-29linux-user: create target_structs header to place ipc_perm and shmid_dsPetar Jovanovic
Creating target_structs header in linux-user/$arch/ and making target_ipc_perm and target_shmid_ds its first inhabitants. The struct defintions may/should be further fine-tuned by arch maintainers.

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.

2011-07-13linux-user: correct syscall 123 on sh4Riku Voipio
As reported by Cédric VINCENT: The syscall #123 on SH4 should be "TARGET_NR_cacheflush" instead of "TARGET_NR_modify_ldt" [1]. The only consequence of this misnaming is that many "Unsupported syscall" warnings are issued when emulating JIT compilers.

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.
