* hw/core/loader: Let load_elf() populate a field with CPU-specific flagsAleksandar Markovic2020-01-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While loading the executable, some platforms (like AVR) need to detect CPU type that executable is built for - and, with this patch, this is enabled by reading the field 'e_flags' of the ELF header of the executable in question. The change expands functionality of the following functions: - load_elf() - load_elf_as() - load_elf_ram() - load_elf_ram_sym() The argument added to these functions is called 'pflags' and is of type 'uint32_t*' (that matches 'pointer to 'elf_word'', 'elf_word' being the type of the field 'e_flags', in both 32-bit and 64-bit variants of ELF header). Callers are allowed to pass NULL as that argument, and in such case no lookup to the field 'e_flags' will happen, and no information will be returned, of course.

* hw/arm/boot: Set NSACR.{CP11, CP10} in dummy SMC setup routineClement Deschamps2019-11-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The boot.c code usually puts the CPU into NS mode directly when it is booting a kernel. Since fc1120a7f5f2d4b6 this has included a requirement to set NSACR to give NS state access to the FPU; we fixed that for the usual code path in ece628fcf6. However, it is also possible for a board model to request an alternative mode of booting, where its 'board_setup' code hook runs in Secure state and is responsible for doing the S->NS transition after it has done whatever work it must do in Secure state. In this situation the board_setup code now also needs to update NSACR. This affects all boards which set info->secure_board_setup, which is currently the 'raspi' and 'highbank' families. They both use the common arm_write_secure_board_setup_dummy_smc(). Set the NSACR CP11 and CP10 bits in the code written by that function, to allow FPU access in Non-Secure state when using dummy SMC setup routine. Otherwise an AArch32 kernel booted on the highbank or raspi boards will UNDEF as soon as it tries to use the FPU. Update the comment describing secure_board_setup to note the new requirements on users of it. This fixes a kernel panic when booting raspbian on raspi2.

| | | | | | | | | | | | | | | | | | | | | | | | If we're booting a Linux kernel directly into Non-Secure state on a CPU which has Secure state, then make sure we set the NSACR CP11 and CP10 bits, so that Non-Secure is allowed to access the FPU. Otherwise an AArch32 kernel will UNDEF as soon as it tries to use the FPU. It used to not matter that we didn't do this until commit fc1120a7f5f2d4b6, where we implemented actually honouring these NSACR bits. The problem only exists for CPUs where EL3 is AArch32; the equivalent AArch64 trap bits are in CPTR_EL3 and are "0 to not trap, 1 to trap", so the reset value of the register permits NS access, unlike NSACR.

* hw/arm/boot: Further improve initrd positioning codePeter Maydell2019-07-261-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit e6b2b20d9735d4ef we made the boot loader code try to avoid putting the initrd on top of the kernel. However the expression used to calculate the start of the initrd: info->initrd_start = info->loader_start + MAX(MIN(info->ram_size / 2, 128 * 1024 * 1024), kernel_size); incorrectly uses 'kernel_size' as the offset within RAM of the highest address to avoid. This is incorrect because the kernel doesn't start at address 0, but slightly higher than that. This means that we can still incorrectly end up overlaying the initrd on the kernel in some cases, for example: * The kernel's image_size is 0x0a7a8000 * The kernel was loaded at 0x40080000 * The end of the kernel is 0x4A828000 * The DTB was loaded at 0x4a800000 To get this right we need to track the actual highest address used by the kernel and use that rather than kernel_size. We already set image_low_addr and image_high_addr for ELF images; set them also for the various other image types we support, and then use image_high_addr as the lowest allowed address for the initrd. (We don't use image_low_addr, but we set it for consistency with the existing code path for ELF files.)

* hw/arm/boot: Honour image size field in AArch64 Image format kernelsPeter Maydell2019-06-171-2/+15
| | | | | | | | | | | | | | | | | | | | | Since Linux v3.17, the kernel's Image header includes a field image_size, which gives the total size of the kernel including unpopulated data sections such as the BSS). If this is present, then return it from load_aarch64_image() as the true size of the kernel rather than just using the size of the Image file itself. This allows the code which calculates where to put the initrd to avoid putting it in the kernel's BSS area. This means that we should be able to reliably load kernel images which are larger than 128MB without accidentally putting the initrd or dtb in locations that clash with the kernel itself.

For some kinds of kernel (self-decompressing 32-bit kernels, and ELF images with a BSS section at the end) we don't know the exact size, but even there we have a minimum size. Put the initrd at least further into RAM than that. For image formats that can give us an exact kernel size, this will mean that we definitely avoid overlaying kernel and initrd.

If a matching ELF Note is found then the specfied function pointer is called to process the ELF note. Passing a NULL function pointer results in ELF Notes being skipped. The first consumer of this functionality is the PVHboot support which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while loading the uncompressed kernel binary in order to discover the boot entry address for the x86/HVM direct boot ABI.

* | hw/arm/boot: Support DTB autoload for firmware-only bootsPeter Maydell2019-02-051-1/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The arm_boot_info struct has a skip_dtb_autoload flag: if this is set to true by the board code then arm_load_kernel() will not load the DTB itself, but will leave this for the board code to do itself later. However, the check for this is done in a code path which is only executed for the case where we load a kernel image file. If we're taking the "boot via firmware" code path then the flag isn't honoured and the DTB is never loaded. We didn't notice this because the only real user of "boot via firmware" that cares about the DTB is the virt board (for UEFI boot), and that always wants skip_dtb_autoload anyway.

However commit: 3b77f6c arm/boot: split load_dtb() from arm_load_kernel() broke CPU reset callback registration in case arm_load_kernel() ... if (!info->kernel_filename || info->firmware_loaded) branch is taken, i.e. it's sufficient to provide a firmware or do not provide kernel on CLI to skip cpu reset callback registration, where before offending commit the callback has been registered unconditionally. Fix it by registering the callback right at the beginning of arm_load_kernel() unconditionally instead of doing it at the end. NOTE: we probably should eliminate that dependency anyways as well as separate arch CPU reset parts from arm_load_kernel() into CPU itself, but that refactoring that I probably would have to do anyways later for CPU hotplug to work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | load_dtb() depends on arm_load_kernel() to figure out place in RAM where it should be loaded, but it's not required for arm_load_kernel() to work. Sometimes it's neccesary for devices added with -device/device_add to be enumerated in DTB as well, which's lead to [1] and surrounding commits to add 2 more machine_done notifiers with non obvious ordering to make dynamic sysbus devices initialization happen in the right order. However instead of moving whole arm_load_kernel() in to machine_done, it's sufficient to move only load_dtb() into virt_machine_done() notifier and remove ArmLoadKernelNotifier/ /PlatformBusFDTNotifierParams notifiers, which saves us ~90LOC and simplifies code flow quite a bit. Later would allow to consolidate DTB generation within one function for 'mach-virt' board and make it reentrant so it could generate updated DTB in device hotplug secenarios. While at it rename load_dtb() to arm_load_dtb() since it's public now. Add additional field skip_dtb_autoload to struct arm_boot_info to allow manual DTB load later in mach-virt and to avoid touching all other boards to explicitly call arm_load_dtb(). 1) (ac9d32e hw/arm/boot: arm_load_kernel implemented as a machine init done notifier) Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Andrew Jones <drjones@redhat.com> Message-id: 1525691524-32265-4-git-send-email-imammedo@redhat.com Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

The functions were renamed with these commands and then compiler issues where manually fixed. find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + Some lines where then manually tweaked to pass checkpatch. The 'qemu: ' prefix was manually removed from the hw/arm/boot.c file.
