The difference now, in comparison with what was being done in version 6, is that now we're doing that for all uses of kernel_entry, not just the one resulting from load_elf_ram_sym(). This will ensure that the current behavior, that is now based on the fact that load_initrd() uses the target_ulong returned by load_kernel(), that happens to be a 32 bit var when running in 32 bit targets, is preserved by doing a explicit 32 bit extract of the uint64_t kernel_entry for 32 bit CPUs. Changes in v10: - patch 1: - extract the lower 32 bits of kernel_entry for all cases, not just the one from load_elf_ram_sym(). - v10 link: https://lists.gnu.org/archive/html/qemu-devel/2023-02/msg00529.html Daniel Henrique Barboza (3): hw/riscv: handle 32 bit CPUs kernel_entry in riscv_load_kernel() hw/riscv/boot.c: consolidate all kernel init in riscv_load_kernel() hw/riscv/boot.c: make riscv_load_initrd() static hw/riscv/boot.c | 97 ++++++++++++++++++++++++-------------- hw/riscv/microchip_pfsoc.c | 12 +---- hw/riscv/opentitan.c | 4 +- hw/riscv/sifive_e.c | 4 +- hw/riscv/sifive_u.c | 12 +---- hw/riscv/spike.c | 14 ++---- hw/riscv/virt.c | 12 +---- include/hw/riscv/boot.h | 3 +- 8 files changed, 78 insertions(+), 80 deletions(-)
