2024-09-22linux-user,hexagon: move to syscalltbl fileLaurent Vivier
Since kernel v6.11 hexagon has moved from syscall_nr.h file to syscall.tbl (36d69c29759e ("hexagon: use new system call table")) Update linux-user scripts to be able to retrieve syscall numbers from linux syscall.tbl instead of syscall_nr.h. New syscall.tbl is imported from linux v6.11 using updated scripts/update-syscalltbl.sh Signed-off-by: Laurent Vivier <laurent@vivier.eu> Message-ID: <20240920151034.859533-5-laurent@vivier.eu> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2023-10-30linux-user/loongarch64: Add vdsoRichard Henderson
Requires a relatively recent binutils version in order to avoid spurious R_LARCH_NONE relocations. The presence of these relocs are diagnosed by our gen-vdso tool.

2023-01-16accel/tcg: Add debuginfo supportIlya Leoshkevich
Add libdw-based functions for loading and querying debuginfo. Load debuginfo from the system and the linux-user loaders. This is useful for the upcoming perf support, which can then put human-readable guest symbols instead of raw guest PCs into perfmap and jitdump files.

2022-01-12user: move common-user includes to a subdirectory of {bsd,linux}-user/Paolo Bonzini
Avoid polluting the compilation of common-user/ with local include files; making an include file available to common-user/ should be a deliberate decision in order to keep a clear interface that can be used by both bsd-user/ and linux-user/.

2021-12-20common-user: Move safe-syscall.* from linux-userRichard Henderson
Move linux-user safe-syscall.S and safe-syscall-error.c to common-user so that bsd-user can also use it. Also move safe-syscall.h to include/user/. Since there is nothing here that is related to the guest, as opposed to the host, build it once.

2021-12-19linux-user: Move syscall error detection into safe_syscall_baseRichard Henderson
The current api from safe_syscall_base() is to return -errno, which is the interface provided by *some* linux kernel abis. The wrapper macro, safe_syscall(), detects error, stores into errno, and returns -1, to match the api of the system syscall(). For those kernel abis that do not return -errno natively, this leads to double syscall error detection. E.g. Linux ppc64, which sets the SO flag for error. Simplify the usage from C by moving the error detection into assembly, and usage from assembly by providing a C helper with which to set errno.

2021-10-18meson: *-user: only descend into *-user when configuredWarner Losh
To increase flexibility, only descend into *-user when that is configured. This allows *-user to selectively include directories based on the host OS which may not exist on all hosts. Adopt Paolo's suggestion of checking the configuration in the directories that know about the configuration.

2021-01-18semihosting: Move ARM semihosting code to shared directoriesKeith Packard
This commit renames two files which provide ARM semihosting support so that they can be shared by other architectures: 1. target/arm/arm-semi.c -> hw/semihosting/common-semi.c 2. linux-user/arm/semihost.c -> linux-user/semihost.c The build system was modified use a new config variable, CONFIG_ARM_COMPATIBLE_SEMIHOSTING, which has been added to the ARM softmmu and linux-user default configs. The contents of the source files has not been changed in this patch.

2020-08-21meson: linux-userMarc-André Lureau
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<SUFFIX>_nr.h for input file syscall<SUFFIX>.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.
