* 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.

| | | | | | | | | 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. Signed-off-by: Petar Jovanovic <petar.jovanovic@imgtec.com> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
* linux-user: Enable NPTL for x86-64Peter Maydell2013-07-221-0/+7
| | | | | | | | | Add x86-64 implementation of cpu_set_tls() (like the kernel, we just have to call do_arch_prctl() to set FS); this allows us to enable NPTL. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

| | | | | | | | | | We can easily set the TLS on i386. Add code to do so.

* 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...)

* linux-user: Move cpu_clone_regs() and cpu_set_tls() into linux-userPeter Maydell2013-07-091-0/+33
| | | | | | | | | | | | | 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.

* linux-user: Merge pread/pwrite into pread64/pwrite64Peter Maydell2012-12-081-2/+2
| | | | | | | | | | | | | | | | The Linux syscalls underlying pread() and pwrite() take a 64 bit offset on all architectures, even if some of them name the syscall "pread/pwrite" rather than "pread64/pwrite64" for historical reasons. So move the four QEMU target architectures (arm, i386, sparc, unicore32) which were defining TARGET_NR_pread/pwrite to define TARGET_NR_pread64/pwrite64 instead, and drop the TARGET_NR_pread/pwrite implementation code completely. (Based on examination of the kernel sources for the four architectures this patch affects.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

* Revert "Get rid of _t suffix"Anthony Liguori2009-10-011-1/+1
| | | | | | | | | | | | 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.
