2023-10-25target/sparc: Remove sparcv7 cpu featuresRichard Henderson1-5/+1
The oldest supported cpu is the microsparc 1; all other cpus use CPU_DEFAULT_FEATURES. Remove the features that must always be present for sparcv7: FLOAT, SWAP, FLUSH, FSQRT, FMUL.

2021-07-12linux-user: Extract target errno to 'target_errno_defs.h'Philippe Mathieu-Daudé1-2/+0
We want to access the target errno indepently of the rest of the linux-user code. Move the header containing the generic errno definitions ('errno_defs.h') to 'generic/target_errno_defs.h', create a new 'target_errno_defs.h' in each target which itself includes 'generic/target_errno_defs.h'.

We want to have one generic target_errno.h (API to access target errno), and will add target errno definitions in target_errno_defs.h. The sparc target already have its errnos in an header, simply rename it.

2020-08-27linux-user: Add strace support for printing arguments of syscalls used to ↵Filip Bozuta1-2/+3
lock and unlock memory This patch implements strace argument printing functionality for following syscalls: * mlock, munlock, mlockall, munlockall - lock and unlock memory int mlock(const void *addr, size_t len) int munlock(const void *addr, size_t len) int mlockall(int flags) int munlockall(void) man page: https://man7.org/linux/man-pages/man2/mlock.2.html Implementation notes: Syscall mlockall() takes an argument that is composed of predefined values which represent flags that determine the type of locking operation that is to be performed. For that reason, a printing function "print_mlockall" was stated in file "strace.list". This printing function uses an already existing function "print_flags()" to print the "flags" argument. These flags are stated inside an array "mlockall_flags" that contains values of type "struct flags". These values are instantiated using an existing macro "FLAG_TARGET()" that crates aproppriate target flag values based on those defined in files '/target_syscall.h'. These target flag values were changed from "TARGET_MLOCKALL_MCL*" to "TARGET_MCL_*" so that they can be aproppriately set and recognised in "strace.c" with "FLAG_TARGET()". Value for "MCL_ONFAULT" was added in this patch. This value was also added in "syscall.c" in function "target_to_host_mlockall_arg()". Because this flag value was added in kernel version 4.4, it is enwrapped in an #ifdef directive (both in "syscall.c" and in "strace.c") as to support older kernel versions. The other syscalls have only primitive argument types, so the rest of the implementation was handled by stating an appropriate printing format in file "strace.list". Syscall mlock2() is not implemented in "syscall.c" and thus it's argument printing is not implemented in this patch.

2016-09-21linux-user: Use correct target SHMLBA in shmat()Peter Maydell1-0/+16
The shmat() handling needs to do target-specific handling of the attach address for shmat(): * if the SHM_RND flag is passed, the address is rounded down to a SHMLBA boundary * if SHM_RND is not passed, then the call is failed EINVAL if the address is not a multiple of SHMLBA Since SHMLBA is target-specific, we need to do this checking and rounding in QEMU and can't leave it up to the host syscall. Allow targets to define TARGET_FORCE_SHMLBA and provide a target_shmlba() function if appropriate, and update do_shmat() to honour them.

2016-07-12linux-user: Clean up target_syscall.h header guardsMarkus Armbruster1-3/+3
Some of them use guard symbol TARGET_SYSCALL_H, but we also have CRIS_SYSCALL_H, MICROBLAZE_SYSCALLS_H, TILEGX_SYSCALLS_H and __UC32_SYSCALL_H__. They all upset scripts/clean-header-guards.pl. Reuse of the same guard symbol TARGET_SYSCALL_H in multiple headers is okay as long as they cannot be included together. The script can't tell, so it warns. The script dislikes the other guard symbols, too. They don't match their file name (they should, to make guard collisions less likely), and __UC32_SYSCALL_H__ is a reserved identifier. Clean them all up: use guard symbol $target_TARGET_SYSCALL_H for linux-user/$target/target_sycall.h.
