2022-04-06Replace TARGET_WORDS_BIGENDIANMarc-André Lureau
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.

2021-09-13linux-user: Split linux-user internals out of qemu.hPeter Maydell
qemu.h is included in various non-linux-user files (which mostly want the TaskState struct and the functions for doing usermode access to guest addresses like lock_user(), unlock_user(), get_user*(), etc). Split out the parts that are only used in linux-user itself into a new user-internals.h. This leaves qemu.h with basically three things: * the definition of the TaskState struct * the user-access functions and macros * do_brk() all of which are needed by code outside linux-user that includes qemu.h. The addition of all the extra #include lines was done with sed -i '/include.*qemu\.h/a #include "user-internals.h"' $(git grep -l 'include.*qemu\.h' linux-user) (and then undoing the change to fpa11.h).

2019-06-10cpu: Replace ENV_GET_CPU with env_cpuRichard Henderson
Now that we have both ArchCPU and CPUArchState, we can define this generically instead of via macro in each target's cpu.h. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Alistair Francis <alistair.francis@wdc.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2014-06-17linux-user/uname: Return correct uname string for x86_64Peter Maydell
We were returning the incorrect uname string (with a hyphen, not an underscore) for x86_64. Fix this by removing the x86_64 special case, since the default "just use UNAME_MACHINE" behaviour suffices. This leaves cpu_to_uname_machine() special cases for only those architectures which need to vary the string based on runtime CPU features.

2014-05-02linux-user: remove configure option for setting uname releaseRiku Voipio
--enable-uname-release was a rather heavyweight hammer, as it allows providing values less that UNAME_MINIMUM_RELEASE. Also, it affects all built linux-user targets, which in most cases is not what user wants. Now that we have UNAME_MINIMUM_RELEASE for all linux-user platforms, we can drop --enable-uname-release and the related CONFIG_UNAME_RELEASE define. Users can still override the variable with QEMU_UNAME=2.6.32 or -r command line option. If distributors need to update a minimum version for a specific target, it can be done by updating UNAME_MINIMUM_RELEASE. Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
