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.

target/alpha: Remove fallback to ev67 cpu class

2024-01-05T15:20:14Z

'ev67' CPU class will be returned to match everything, which makes no sense as mentioned in the comments. Remove the logic to fall back to 'ev67' CPU class to match everything.

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: Add translation for argument of msync()

2023-03-10T19:45:47Z

msync() uses the flags MS_ASYNC, MS_INVALIDATE and MS_SYNC, which differ between platforms, specifcally on alpha and hppa. Add a target to host translation for those and wire up a nicer strace output. This fixes the testsuite of the macaulay2 debian package with a hppa-linux guest on a x86-64 host.

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.
