X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Peter Maydell , qemu-arm Errors-To: qemu-devel-bounces+importer=patchew.org@nongnu.org Sender: "Qemu-devel" Content-Type: text/plain; charset="utf-8" noload kernels are loaded with the u-boot image header and as a result the header size needs adding to the entry point. Fake up a hdr so the kernel image is loaded at the right address and the entry point is adjusted appropriately. The default location for the uboot file is 32MiB above bottom of DRAM. This matches the recommendation in Documentation/arm/Booting. Clarify the load_uimage API to state the passing of a load address when an image doesn't specify one, or when loading a ramdisk is expected. Adjust callers of load_uimage, etc. Signed-off-by: Nick Hudson --- hw/arm/boot.c | 8 +++++--- hw/core/loader.c | 19 ++++++++++++++++--- hw/core/uboot_image.h | 1 + hw/microblaze/boot.c | 2 +- hw/nios2/boot.c | 2 +- hw/ppc/e500.c | 1 + hw/ppc/ppc440_bamboo.c | 2 +- hw/ppc/sam460ex.c | 2 +- include/hw/loader.h | 7 ++++++- 9 files changed, 33 insertions(+), 11 deletions(-) diff --git a/hw/arm/boot.c b/hw/arm/boot.c index 94fce12802..c7a67af7a9 100644 --- a/hw/arm/boot.c +++ b/hw/arm/boot.c @@ -30,8 +30,9 @@ * Documentation/arm/Booting and Documentation/arm64/booting.txt * They have different preferred image load offsets from system RAM base. */ -#define KERNEL_ARGS_ADDR 0x100 -#define KERNEL_LOAD_ADDR 0x00010000 +#define KERNEL_ARGS_ADDR 0x100 +#define KERNEL_NOLOAD_ADDR 0x02000000 +#define KERNEL_LOAD_ADDR 0x00010000 #define KERNEL64_LOAD_ADDR 0x00080000 =20 #define ARM64_TEXT_OFFSET_OFFSET 8 @@ -1082,7 +1083,8 @@ void arm_load_kernel(ARMCPU *cpu, struct arm_boot_inf= o *info) } entry =3D elf_entry; if (kernel_size < 0) { - kernel_size =3D load_uimage_as(info->kernel_filename, &entry, NULL, + uint64_t loadaddr =3D info->loader_start + KERNEL_NOLOAD_ADDR; + kernel_size =3D load_uimage_as(info->kernel_filename, &entry, &loa= daddr, &is_linux, NULL, NULL, as); } if (arm_feature(&cpu->env, ARM_FEATURE_AARCH64) && kernel_size < 0) { diff --git a/hw/core/loader.c b/hw/core/loader.c index fa41842280..c7182dfa64 100644 --- a/hw/core/loader.c +++ b/hw/core/loader.c @@ -613,13 +613,26 @@ static int load_uboot_image(const char *filename, hwa= ddr *ep, hwaddr *loadaddr, goto out; =20 if (hdr->ih_type !=3D image_type) { - fprintf(stderr, "Wrong image type %d, expected %d\n", hdr->ih_type, - image_type); - goto out; + if (!(image_type =3D=3D IH_TYPE_KERNEL && + hdr->ih_type =3D=3D IH_TYPE_KERNEL_NOLOAD)) { + fprintf(stderr, "Wrong image type %d, expected %d\n", hdr->ih_= type, + image_type); + goto out; + } } =20 /* TODO: Implement other image types. */ switch (hdr->ih_type) { + case IH_TYPE_KERNEL_NOLOAD: + if (!loadaddr || *loadaddr =3D=3D LOAD_UIMAGE_LOADADDR_INVALID) { + fprintf(stderr, "this image format (kernel_noload) cannot be " + "loaded on this machine type"); + goto out; + } + + hdr->ih_load =3D *loadaddr + sizeof(*hdr); + hdr->ih_ep +=3D hdr->ih_load; + /* fall through */ case IH_TYPE_KERNEL: address =3D hdr->ih_load; if (translate_fn) { diff --git a/hw/core/uboot_image.h b/hw/core/uboot_image.h index 34c11a70a6..608022de6e 100644 --- a/hw/core/uboot_image.h +++ b/hw/core/uboot_image.h @@ -124,6 +124,7 @@ #define IH_TYPE_SCRIPT 6 /* Script file */ #define IH_TYPE_FILESYSTEM 7 /* Filesystem Image (any type) */ #define IH_TYPE_FLATDT 8 /* Binary Flat Device Tree Blob */ +#define IH_TYPE_KERNEL_NOLOAD 14 /* OS Kernel Image (noload) */ =20 /* * Compression Types diff --git a/hw/microblaze/boot.c b/hw/microblaze/boot.c index 35bfeda7aa..489ab839b7 100644 --- a/hw/microblaze/boot.c +++ b/hw/microblaze/boot.c @@ -156,7 +156,7 @@ void microblaze_load_kernel(MicroBlazeCPU *cpu, hwaddr = ddr_base, =20 /* If it wasn't an ELF image, try an u-boot image. */ if (kernel_size < 0) { - hwaddr uentry, loadaddr; + hwaddr uentry, loadaddr =3D LOAD_UIMAGE_LOADADDR_INVALID; =20 kernel_size =3D load_uimage(kernel_filename, &uentry, &loadadd= r, 0, NULL, NULL); diff --git a/hw/nios2/boot.c b/hw/nios2/boot.c index 4bb5b601d3..ed5cb28e94 100644 --- a/hw/nios2/boot.c +++ b/hw/nios2/boot.c @@ -161,7 +161,7 @@ void nios2_load_kernel(Nios2CPU *cpu, hwaddr ddr_base, =20 /* If it wasn't an ELF image, try an u-boot image. */ if (kernel_size < 0) { - hwaddr uentry, loadaddr; + hwaddr uentry, loadaddr =3D LOAD_UIMAGE_LOADADDR_INVALID; =20 kernel_size =3D load_uimage(kernel_filename, &uentry, &loadadd= r, 0, NULL, NULL); diff --git a/hw/ppc/e500.c b/hw/ppc/e500.c index b20fea0dfc..0581e9e3d4 100644 --- a/hw/ppc/e500.c +++ b/hw/ppc/e500.c @@ -995,6 +995,7 @@ void ppce500_init(MachineState *machine) * Hrm.
