* linux-user: Support target-to-host translation of mlockall argumentTom Musta2014-08-221-0/+2
| | | | | | | | | | | | | 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>
* linux-user: Minimum Sig Handler Stack Size for PPC64 ELF V2Tom Musta2014-08-221-0/+2
| | | | | | | | 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>
* target-ppc: Support little-endian PPC64 in user mode.Doug Kwan2014-06-161-0/+4
| | | | | | | | | | Look at ELF header to determine ABI version on PPC64. This is required for executing the first instruction correctly. Also print correct machine name in uname() system call.

* linux-user: set minimum kernel version to 2.6.32Riku Voipio2014-03-101-0/+1
| | | | | | | | | | | | | | | 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.

* linux-user: Clean up handling of clone() argument orderPeter Maydell2013-07-221-0/+2
| | | | | | | | | | | | | | | | | | | Linux manages to have three separate orderings of the arguments to the clone() syscall on different architectures. In the kernel these are selected via CONFIG_CLONE_BACKWARDS and CONFIG_CLONE_BACKWARDS2. Clean up our implementation of this to use similar #define names rather than a TARGET_* ifdef ladder. This includes behaviour changes fixing bugs on cris, x86-64, m68k, openrisc and unicore32. cris had explicit but wrong handling; the others were just incorrectly using QEMU's default, which happened to be the equivalent of CONFIG_CLONE_BACKWARDS. (unicore32 appears to be broken in the mainline kernel in that it tries to use arg3 for both parent_tidptr and newtls simultaneously -- we don't attempt to emulate this bug...)
