linaro-edk2-2014.10

by Leif Lindholm

has now been tagged, pushed and built. Images available in: http://snapshots.linaro.org/components/kernel/linaro-edk2/28 Changes since 2014.09: - All platforms build successfully. - QEMU platforms added, both aarch32 and aarch64. - Some bugfixes in core code. Known issues: - The VExpress A9 topic branch was broken, so only the upstream support was included. This builds correctly, but results in the image being built in a different directory, so it was not copied into the release.

[PATCH V2 0/4] arm64: Add multiboot support (via fdt) for Xen boot

by Fu Wei

arm64:Add multiboot support (via fdt) for Xen boot - This multiboot support is built into linux module for aarch64. - The implementation for Xen is following <Multiboot on ARM Specification>: http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/Multiboot and xen/docs/misc/arm/device-tree/booting.txt in Xen source code. - The example of this support is <How to boot Xen with GRUB on AArch64 the Foundation FVP model> https://wiki.linaro.org/LEG/Engineering/Grub2/Xen_booting_on_Foundation_FVP… - This adds support for the Xen Multiboot on ARM specification for arm64, enabling config file portability across the architectures. - The multiboot command is currently x86-only, so reusing these command names should not conflict with any future additions of ARM support to multiboot2. - The reason of adding this functionality to the existing "linux" module rather than "multiboot(2)" (1)multiboot is x86 only (2)Multiboot is added to "linux" module because it reuses existing code. - Some changes in original linux module code Move some #define from grub-core/loader/arm64/linux.c to include/grub/arm64/linux.h Reason: (1)make code more orderly (2)these #define can be used by other files which includs include/grub/arm64/linux.h Share some functions and variables for multiboot.c - Add grub_fdt_set_reg64 macro into fdt.h header file for inserting "reg" properiy, while #address-cells = <0x2> and #size-cells = <0x2> This multiboot support will be built in linux module for aarch64, and can not be used alone.

[PATCH V2 3/3] arm64: Add multiboot support file

by Fu Wei

arm64: Add multiboot support file grub-core/loader/arm64/multiboot.c and dependent header file include/grub/arm64/multiboot.h Add commands register code and header file into grub-core/loader/arm64/linux.c - The implementation for Xen is following <Multiboot on ARM Specification>: http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/Multiboot and xen/docs/misc/arm/device-tree/booting.txt in Xen source code. - The example of this support is <How to boot Xen with GRUB on AArch64 the Foundation FVP model> https://wiki.linaro.org/LEG/Engineering/Grub2/Xen_booting_on_Foundation_FVP… - This adds support for the Xen Multiboot on ARM specification for arm64, enabling config file portability across the architectures. - The multiboot command is currently x86-only, so reusing these command names should not conflict with any future additions of ARM support to multiboot2. - The reason of adding this functionality to the existing "linux" module rather than "multiboot(2)" (1)multiboot is x86 only (2)Multiboot is added to "linux" module because it reuses existing code. - This multiboot support is built into linux module for aarch64.

Re: [Linaro-uefi] Fwd: Building UEFI (14.09)

by Olivier Brunel

Hi all, I managed to build it in the end. My solution is: Use Python 2.7.2. Don't use GCC 4.9 14.09 but GCC 4.9 14.07. It was just a matter of version but I can't understand wy it does not work with 14.09 when on the Linaro Website those vesions are under components/toolchain for the release I want to use which is the 14.09. Well anyway, thanks for your support.

[PATCH 00/11] arm64 EFI overhaul

by Ard Biesheuvel

I started out tweaking some things for kexec, and then things got out of hand... Anyway, there is hopefully some stuff here that we will reuse, but I am not getting my hopes up that this will land upstream unmodified. The main premise of these patches is that, in order to support kexec, we need to add code to the kernel that is able to deal with the state of the firmware after SetVirtualAddressMap() has been called. However, if we are going to deal with that anyway, why not make that the default state, and have only a single code path for both cases. This means SVAM() needs to move to the stub, and hence the code that invents the layout needs to move with it. The result is that the kernel proper is entered with the virt_addr members of all EFI_MEMORY_RUNTIME regions assigned, and the mapping installled in UEFI. The kernel proper needs to set up the page tables, and switch to them while performing the runtime services calls. Note that there is also an efi_to_phys() to translate the values of the fw_vendor and tables fields of the EFI system table. Again, this is something we need to do anyway under kexec, or we end up handing over state between one kernel and the next, which implies different code paths between non-kexec and kexec. One thing that may stand out is the reordering of the memory map. The reason for doing this is that we can use the same memory map as input to SVAM(). The alternative is allocating memory for it using boot services, but that clutters up the existing logic a bit between getting the memory map, populating the fdt, and loop again if it didn't fit. The current code works perfectly fine, but I am aware that it is an acquired taste :-) The first 2 patches are stuff that is missing from Matt Fleming's efi-next branch, which is what these patches are based on, so I included them for completeness. The meat is in patch #9, everything before that is groundwork and/or fixes, after that is dropping stuff that we don't need any longer. Ard Biesheuvel (9): arm64/efi: reserve regions of type ACPI_MEMORY_NVS arm64/efi: drop redundant set_bit(EFI_CONFIG_TABLES) arm64/efi: use UEFI memory map unconditionally if available arm64/mm: add explicit struct_mm argument to __create_mapping() arm64/mm: add create_pgd_mapping() to create private page tables efi: split off remapping code from efi_config_init() arm64/efi: move SetVirtualAddressMap() to UEFI stub arm64/efi: remove free_boot_services() and friends arm64/efi: remove idmap manipulations from UEFI code Leif Lindholm (1): arm64: ignore DT memreserve entries when booting in UEFI mode Semen Protsenko (1): efi/arm64: Store Runtime Services revision arch/arm64/include/asm/efi.h | 23 ++- arch/arm64/include/asm/mmu.h | 12 +- arch/arm64/kernel/efi.c | 368 +++++++++++++------------------------ arch/arm64/kernel/setup.c | 2 +- arch/arm64/mm/init.c | 4 +- arch/arm64/mm/mmu.c | 57 +++--- drivers/firmware/efi/efi.c | 49 +++-- drivers/firmware/efi/libstub/fdt.c | 110 ++++++++++- include/linux/efi.h | 2 + 9 files changed, 328 insertions(+), 299 deletions(-) -- 1.8.3.2

[PATCH 01/11] efi/arm64: Store Runtime Services revision

From: Semen Protsenko <semen.protsenko(a)linaro.org> "efi" global data structure contains "runtime_version" field which must be assigned in order to use it later in Runtime Services virtual calls (virt_efi_* functions).

So, I think I might have seen this at some point, but I'm not getting it now. Could your gcc be defaulting to 32-bit or something? / Leif
