2025-01-31hw/mips/loongson3: Propagate cpu_count to init_loongson_params()Philippe Mathieu-Daudé1-5/+6
Propagate the %cpu_count from the machine file, allowing to remove the "hw/boards.h" dependency (which is machine specific) from loongson3_bootp.

2025-01-31hw/mips/loongson3_bootp: Include missing headersPhilippe Mathieu-Daudé1-0/+2
MemMapEntry is declared in "exec/hwaddr.h", cpu_to_le32() in "qemu/bswap.h". These headers are indirectly included via "cpu.h". Include them explicitly in order to avoid when removing "cpu.h": In file included from ../../hw/mips/loongson3_bootp.c:27: hw/mips/loongson3_bootp.h:234:14: error: unknown type name 'MemMapEntry' 234 | extern const MemMapEntry virt_memmap[]; | ^ hw/mips/loongson3_bootp.c:33:18: error: call to undeclared function 'cpu_to_le32'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] 33 | c->cputype = cpu_to_le32(Loongson_3A); | ^ Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20250115232952.31166-6-philmd@linaro.org>

2024-05-09hw/mips/loongson3_virt: Emulate suspend functionJiaxun Yang1-0/+1
Suspend function is emulated as what hardware actually do. Doorbell register fields are updates to include suspend value, suspend vector is encoded in firmware blob and fw_cfg is updated to include S3 bits as what x86 did.
