linux-user/s390x: Save/restore fpc when handling a signal

2022-09-27T11:19:05+00:00

Linux kernel does this in fpregs_store() and fpregs_load(), so qemu-user should do this as well. Found by running valgrind's none/tests/s390x/test_sig.

linux-user: Provide MADV_* definitions

2022-09-27T07:30:09+00:00

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.

linux-user/s390x: Fix unwinding from signal handlers

2022-05-23T20:52:27+00:00

Commit 31330e6cecfd ("linux-user/s390x: Implement setup_sigtramp") removed an unused field from rt_sigframe, disturbing offsets of other fields and breaking unwinding from signal handlers (e.g. libgcc's s390_fallback_frame() relies on this struct having a specific layout). Restore the field and add a comment.

linux-user: Split out do_prctl and subroutines

2022-01-06T10:40:52+00:00

Since the prctl constants are supposed to be generic, supply any that are not provided by the host. Split out subroutines for PR_GET_FP_MODE, PR_SET_FP_MODE, PR_GET_VL, PR_SET_VL, PR_RESET_KEYS, PR_SET_TAGGED_ADDR_CTRL, PR_GET_TAGGED_ADDR_CTRL. Return EINVAL for guests that do not support these options rather than pass them on to the host.
