linux-user: Drop unicore32 code

2018-03-09T18:17:27+00:00

We dropped the unicore32-linux-user target in commit 5e2b40f7271cf9 in 2016. Nobody has made any attempt to fix the issues that caused us to drop it, so remove the associated code. (The system emulation parts of unicore32 remain.) Signed-off-by: Peter Maydell Reviewed-by: Laurent Vivier Message-Id: <20180308144733.25615-2-peter.maydell@linaro.org> Signed-off-by: Laurent Vivier

linux-user: Move CPU type name selection to a function

2018-02-25T16:27:41+00:00

Instead of a sequence of "#if ... #endif" move the selection to a function in linux-user/*/target_elf.h We can't add them in linux-user/*/target_cpu.h because we will need to include "elf.h" to use ELF flags with eflags, and including "elf.h" in "target_cpu.h" introduces some conflicts in elfload.c Suggested-by: Richard Henderson Signed-off-by: Laurent Vivier Reviewed-by: Richard Henderson Reviewed-by: Philippe Mathieu-Daudé Message-Id: <20180220173307.25125-2-laurent@vivier.eu>

linux-user: Clean up target_structs.h header guards

2016-07-12T14:19:16+00:00

These headers all use TARGET_STRUCTS_H as header guard symbol. Reuse of the same guard symbol in multiple headers is okay as long as they cannot be included together. Since we can avoid guard symbol reuse easily, do so: use guard symbol $target_TARGET_STRUCTS_H for linux-user/$target/target_structs.h.

linux-user: Clean up target_syscall.h header guards

2016-07-12T14:19:16+00:00

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. Signed-off-by: Markus Armbruster Reviewed-by: Richard Henderson

build: [linux-user] Rename "syscall.h" to "target_syscall.h" in target directories

2016-02-23T19:25:09+00:00

This fixes double-definitions in linux-user builds when using the UST tracing backend (which indirectly includes the system's "syscall.h"). Signed-off-by: Lluís Vilanova Reviewed-by: Peter Maydell Signed-off-by: Riku Voipio

unicore32: convert get_sp_from_cpustate from macro to inline

2016-01-10T07:25:38+00:00

All other architectures define get_sp_from_cpustate as an inline function, only unicore32 uses a #define. With this, some usages are impossible, for example, enabling sigaltstack in linux-user/syscall.c results in linux-user/syscall.c: In function ‘do_syscall’: linux-user/syscall.c:8299:39: error: dereferencing ‘void *’ pointer [-Werror] get_sp_from_cpustate(arg1, arg2, get_sp_from_cpustate((CPUArchState *)cpu_env)); ^ linux-user/syscall.c:8299:39: error: request for member ‘regs’ in something not a structure or union Signed-off-by: Michael Tokarev Reviewed-by: Peter Maydell

linux-user: Support target-to-host translation of mlockall argument

2014-08-22T12:06:35+00:00

The argument to the mlockall system call is not necessarily the same on all platforms and thus may require translation prior to passing to the host. For example, PowerPC 64 bit platforms define values for MCL_CURRENT (0x2000) and MCL_FUTURE (0x4000) which are different from Intel platforms (0x1 and 0x2, respectively) Signed-off-by: Tom Musta Signed-off-by: Riku Voipio
