linux-user: Move tswap_siginfo out of target code

2024-03-13T11:43:52Z

Move tswap_siginfo from target code to handle_pending_signal. This will allow some cleanups and having the siginfo ready to be used in gdbstub.

{linux,bsd}-user: Introduce get_task_state()

2024-03-06T12:35:19Z

A CPU's TaskState is stored in the CPUState's void *opaque field, accessing which is somewhat awkward due to having to use a cast. Introduce a wrapper and use it everywhere.

linux-user: xtensa: fix signal delivery in FDPIC

2023-11-19T18:56:26Z

In FDPIC signal handlers are passed around as FD pointers. Actual code address and GOT pointer must be fetched from memory by the QEMU code that implements kernel signal delivery functionality. This change is equivalent to the following kernel change: 9c2cc74fb31e ("xtensa: fix signal delivery to FDPIC process") Cc: qemu-stable@nongnu.org Fixes: d2796be69d7c ("linux-user: add support for xtensa FDPIC") Reviewed-by: Richard Henderson Signed-off-by: Max Filippov

linux-user: Split out cpu/target_proc.h

2023-09-01T20:33:09Z

Move the various open_cpuinfo functions into new files. Move the m68k open_hardware function as well. All other guest architectures get a boilerplate empty file. Tested-by: Helge Deller Reviewed-by: Philippe Mathieu-Daudé Signed-off-by: Richard Henderson

linux-user: Define ELF_ET_DYN_BASE in $guest/target_mman.h

2023-08-08T20:27:15Z

Copy each guest kernel's default value, then bound it against reserved_va or the host address space. Tested-by: Helge Deller Reviewed-by: Helge Deller Signed-off-by: Richard Henderson

linux-user: Define TASK_UNMAPPED_BASE in $guest/target_mman.h

2023-08-08T20:24:27Z

Provide default values that are as close as possible to the values used by the guest's kernel. Tested-by: Helge Deller Reviewed-by: Helge Deller Reviewed-by: Akihiko Odaki Reviewed-by: Alex Bennée Signed-off-by: Richard Henderson

linux-user: Provide MADV_* definitions

Provide MADV_* definitions using target_mman.h header, similar to what kernel does. Most architectures use the same values, with the exception of alpha and hppa.

Replace TARGET_WORDS_BIGENDIAN

2022-04-06T08:50:37Z

Convert the TARGET_WORDS_BIGENDIAN macro, similarly to what was done with HOST_BIG_ENDIAN. The new TARGET_BIG_ENDIAN macro is either 0 or 1, and thus should always be defined to prevent misuse.
