Introduces support to locate a loaded initramdisk. For this purpose, we introduce required platform API definitons. The idea is that an Unikraft application finds an initramdisk by querying the memory regions. This is similar to the detection of memory regions that can be used for the heap. This series inplements initrd support for KVM on x86. Additionally, this series is reorganizing KVMs way to store detected platform configuration during boot: Instead of having individual platform-global variables (e.g., _libkvmplat_heap_start, _libkvmplat_stack_top, _libkvmplat_mem_end), we introduce a single platform-global configuration struct. This is done for readability reasons. Changes v2: - Ignore zero-sized initramdisks - Add helper macro for finding the first initramdisk (with this turn also simplify boot code that initializes the heap) Simon Kuenzer (8): include/plat: Helpers for iterating over memory regions lib/ukboot: Simplify heap initialization include/plat: Add flags for initramdisk memory regions include/plat: Helper for finding first initrd include/essentials: Introduce range test macros plat/kvm: Introduce platform configuration struct plat/kvm: Add initrd fields to configuration struct plat/kvm: x86: Retrieve initrd location from Multiboot include/uk/essentials.h | 20 ++++ include/uk/plat/memory.h | 74 +++++++++++++- lib/ukboot/boot.c | 58 ++++------- plat/common/arm/pl011.c | 15 +-- plat/common/arm/time.c | 13 ++- plat/kvm/arm/setup.c | 67 ++++++++----- plat/kvm/include/kvm/config.h | 66 ++++++++++++ plat/kvm/memory.c | 49 ++++++--- plat/kvm/x86/setup.c | 182 +++++++++++++++++++++++++++++++--- 9 files changed, 436 insertions(+), 108 deletions(-) create mode 100644 plat/kvm/include/kvm/config.h -- 2.20.1 _______________________________________________ Minios-devel mailing list Minios-devel@xxxxxxxxxxxxxxxxxxxx https://lists.xenproject.org/mailman/listinfo/minios-devel
