linux-user/sparc: Merge sparc64/ into sparc/

2021-05-15T19:43:23+00:00

All of the source and header files already defer to sparc via #include. The syscall.tbl and syscallhdr.sh files could not do the same, but are identical. Signed-off-by: Richard Henderson Message-Id: <20210426025334.1168495-12-richard.henderson@linaro.org> Signed-off-by: Laurent Vivier

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 missing termbits types and values definitions

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

This patch introduces missing target types ('target_flag_t', 'target_cc_t', 'target_speed_t') in a few 'termibts.h' header files. Also, two missing values ('TARGET_IUTF8' and 'TARGET_EXTPROC') were also added. These values were also added in file 'syscall.c' in bitmask tables 'iflag_tbl[]' and 'lflag_tbl[]' which are used to convert values of 'struct termios' between target and host.

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.

meson: linux-user

2020-08-21T10:30:38+00:00

The most interesting or most complicated part here is the syscall_nr.h generators. In order to keep the generation logic all in meson.build, I am adding to config_target the name of the .tbl file, and making the generated file syscall_nr.h for input file syscall.tbl. For architectures where the input file is not named syscall_nr.tbl, syscall_nr.h has to be a source file; it's just a forwarder for x86 (i386/x86_64), while for MIPS64 it chooses between N32 and N64 ABIs.
