Remove deprecated target tilegx

2021-03-09T10:26:32+00:00

TILE-Gx was only implemented in linux-user mode, but support for this CPU was removed from the upstream Linux kernel in 2018, and it has also been dropped from glibc, so there is no new Linux development taking place with this architecture. For running the old binaries, users can simply use older versions of QEMU.

linux user: Fix Lesser GPL version number

2020-11-15T15:41:26+00:00

There is no "version 2" of the "Lesser" General Public License. It is either "GPL version 2.0" or "Lesser GPL version 2.1". This patch replaces all occurrences of "Lesser GPL version 2" with "Lesser GPL version 2.1" in comment section.

linux-user: Add generic 'termbits.h' for some archs

2020-08-27T10:29:50+00:00

This patch introduces a generic 'termbits.h' file for following archs: 'aarch64', 'arm', 'i386, 'm68k', 'microblaze', 'nios2', 'openrisc', 'riscv', 's390x', 'x86_64'. Since all of these archs have the same termios flag values and same ioctl_tty numbers, there is no need for a separate 'termbits.h' file for each one of them. For that reason one generic 'termbits.h' file was added for all of them and an '#include' directive was added for this generic file in every arch 'termbits.h' file. Also, some of the flag values that were missing were added in this generic file so that it matches the generic 'termibts.h' and 'ioctls.h' files from the kernel: 'asm-generic/termbits.h' and 'asm-generic/ioctls.h'.

linux-user: Add strace support for printing arguments of syscalls used to lock and unlock memory

2020-08-27T10:29:50+00:00

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.

linux-user: Rename cpu_clone_regs to cpu_clone_regs_child

2019-11-06T12:42:34+00:00

We will need a target-specific hook for adjusting registers in the parent during clone. To avoid confusion, rename the one we have to make it clear it affects the child. At the same time, pass in the flags from the clone syscall. We will need them for correct behaviour for Sparc.
