Instead of loading kernels, device trees, and the like to the system address space, use the CPU's address space. This is important if we're trying to load the file to memory or via an alias memory region that is provided by an SoC object and thus not mapped into the system address space.

qemu-common.h includes qemu/option.h, but most places that include the former don't actually need the latter. Drop the include, and add it to the places that actually need it. While there, drop superfluous includes of both headers, and separate #include from file comment with a blank line. This cleanup makes the number of objects depending on qemu/option.h drop from 4545 (out of 4743) to 284 in my "build everything" tree.

So after attempts to load the arm64 kernel image as an ELF file or as a U-Boot image have failed (both of which have their own way of specifying the load offset), try to determine the TEXT_OFFSET from the image after loading it but before mapping it as a ROM mapping into the guest address space.

Commit 57cb38b3 included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

Some CPUs are of an opposite data-endianness to other components in the system. Sometimes elfs have the data sections layed out with this CPU data-endianness accounting for when loaded via the CPU, so byte swaps (relative to other system components) will occur. The leading example, is ARM's BE32 mode, which is is basically LE with address manipulation on half-word and byte accesses to access the hw/byte reversed address. This means that word data is invariant across LE and BE32. This also means that instructions are still LE. The expectation is that the elf will be loaded via the CPU in this endianness scheme, which means the data in the elf is reversed at compile time. As QEMU loads via the system memory directly, rather than the CPU, we need a mechanism to reverse elf data endianness to implement this possibility.

For ARM we have a little minimalist bootloader in hw/arm/boot.c which takes the place of firmware if we're directly booting a Linux kernel. Unfortunately a few devices need special case handling in this situation to do the initialization which on real hardware would be done by firmware. (In particular if we're booting a kernel in NonSecure state then we need to make a TZ-aware GIC put all its interrupts into Group 1, or the guest will be unable to use them.) Create a new QOM interface which can be implemented by devices which need to do something different from their default reset behaviour. The callback will be called after machine initialization and before first reset.

The Linux kernel on aarch64 creates a page table entry at early bootup that spans the 2MB range on memory spanning the fdt start address: [ ALIGN_DOWN(fdt, 2MB) ... ALIGN_DOWN(fdt, 2MB) + 2MB ] This means that when our current 4k alignment happens to fall at the end of the aligned region, Linux tries to access memory that is not mapped. The easy fix is to instead increase the alignment to 2MB, making Linux's logic always succeed. We leave the existing 4k alignment for 32bit kernels to not cause any regressions due to space constraints.

Introduce the new boolean field "arm_boot_info.firmware_loaded". When this field is set, it means that the portion of guest DRAM that the VCPU normally starts to execute, or the pflash chip that the VCPU normally starts to execute, has been populated by board-specific code with full-fledged guest firmware code, before the board calls arm_load_kernel(). Simultaneously, "arm_boot_info.firmware_loaded" guarantees that the board code has set up the global firmware config instance, for arm_load_kernel() to find with fw_cfg_find(). Guest kernel (-kernel) and guest firmware (-bios, -pflash) has always been possible to specify independently on the command line. The following cases should be considered: nr -bios -pflash -kernel description unit#0 -- ------- ------- ------- ------------------------------------------- 1 present present absent Board code rejects this case, -bios and present present present -pflash unit#0 are exclusive. Left intact by this patch. 2 absent absent present Traditional kernel loading, with qemu's minimal board firmware. Left intact by this patch. 3 absent present absent Preexistent case for booting guest firmware present absent absent loaded with -bios or -pflash. Left intact by this patch. 4 absent absent absent Preexistent case for not loading any firmware or kernel up-front. Left intact by this patch. 5 present absent present New case introduced by this patch: kernel absent present present image is passed to externally loaded firmware in unmodified form, using fw_cfg. An easy way to see that this patch doesn't interfere with existing cases is to realize that "info->firmware_loaded" is constant zero at this point. Which makes the "outer" condition unchanged, and the "inner" condition (with the fw_cfg-related code) dead.

Add support for loading DTB images when booting ELF images using -kernel. If there are no conflicts with the placement of the ELF segments, the DTB image is loaded at the base of RAM.

If we are running the 'virt' machine, we may have a device tree blob but no kernel to supply it to if no -kernel option was passed. In that case, copy it to the base of RAM where it can be picked up by a bootloader.

Add an address limit input parameter to load_dtb() so that we can tell load_dtb() how much memory the dtb is allowed to consume. If the dtb doesn't fit, return 0, otherwise return the actual size of the loaded dtb.

In order to make the device tree blob (DTB) available in memory not only at first boot, but also after system reset, use rom_blob_add_fixed() to install it into memory.

On aarch64 it is the bootloader's job to uncompress the kernel. UEFI and u-boot bootloaders do this automatically when the kernel is gzip-compressed. However the qemu -kernel option does not do this. The following command does not work: qemu-system-aarch64 [...] -kernel /boot/vmlinuz because it tries to execute the gzip-compressed data. This commit lets gzip-compressed kernels be uncompressed transparently. Currently this is only done when emulating aarch64. Signed-off-by: NRichard W.M.

The code in do_cpu_reset() correctly handled AArch64 CPUs when running Linux kernels, but was missing code in the branch of the if() that deals with loading ELF files. Correctly jump to the ELF entry point on reset rather than leaving the reset PC at zero.

When trying to load an ELF file specified via -kernel, we need to pass load_elf() the ELF machine type corresponding to the CPU we're booting with, not the one corresponding to the softmmu binary we happen to be running. (The two are different in the case of loading a 32-bit ARM ELF file into a 32 bit CPU being emulated by qemu-system aarch64.) This was causing us to incorrectly fail to load ELF images in this situation.

The code which decides whether to set up the ATAGS data structure on reset was using the wrong conditional, which meant we were creating an ATAGS structure when doing a device-tree boot if the dtb was autogenerated by the board. This is harmless, but unnecessary, so bring it in to line with user-provided-dtb boots.
