* linux-user: Standardize on ELF_MACHINE not ELF_ARCHRichard Henderson2025-08-301-1/+1
| | | | | | | | | | | | | | | | | PowerPC was the one outlier that defined both ELF_ARCH and ELF_MACHINE; ELF_ARCH was defined incorrectly, necessitating the definition of elf_check_arch. However, the elf file header field in question is called e_machine, so ELF_MACHINE is in fact the better name. Mechanically change most target/target_elf.h files, then adjust ppc/target_elf.h manually. Do not provide a default for ELF_MACHINE.

* linux-user: Move get_elf_hwcap to riscv/elfload.cRichard Henderson2025-08-281-0/+2
| | | | | | | | | Change the return type to abi_ulong, and pass in the cpu. As this is the last instance of get_elf_hwcap to be converted, remove the ifdef around the declaration in loader.h.

* linux-user: Move get_elf_cpu_model to target/elfload.cRichard Henderson2025-08-281-4/+1
| | | | | | | | | | Rename from cpu_get_model to emphasize that this is an elf-specific function. Declare the function once in loader.h. This frees up target_elf.h for other uses. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
* linux-user/riscv: change default cpu to 'max'Daniel Henrique Barboza2023-11-071-2/+1
| | | | | | | | | | | | | | | | | | | | | Commit f57d5f8004 deprecated the 'any' CPU type but failed to change the default CPU for linux-user. The result is that all linux-users invocations that doesn't specify a different CPU started to show a deprecation warning: $ ./build/qemu-riscv64 ./foo-novect.out qemu-riscv64: warning: The 'any' CPU is deprecated and will be removed in the future. Change the default CPU for RISC-V linux-user from 'any' to 'max'.
