[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v5 00/44] Boot modules for Hyperlaunch
The Boot Modules for Hyperlaunch series is an effort to split out preliminary changes necessary for the introduction of the Hyperlaunch domain builder logic. These preliminary changes revolve around introducing the struct boot_module and struct boot_domain structures. This includes converting the dom0 construction path to use these structures. These abstractions lay the groundwork to transform and extend the dom0 construction logic into a limited, but general domain builder. The splitting of Hyperlaunch into a set of series are twofold, to reduce the effort in reviewing a much larger series, and to reduce the effort in handling the knock-on effects to the construction logic from requested review changes. Much thanks to AMD for supporting this work. Documentation on Hyperlaunch: https://wiki.xenproject.org/wiki/Hyperlaunch Original Hyperlaunch v1 patch series: https://lists.xenproject.org/archives/html/xen-devel/2022-07/msg00345.html V/r, Daniel P. Smith Changes since v4: - added requested inline code comments - moved instance of struct boot_info to unit level and extern'ed - array of struct boot_module moved into struct boot_info - renamed function to multiboot_fill_bootinfo, now returns *struct boot_info - multiboot_fill_bootinfo changed to take multiboot_info_t addr as param - added missing guard that checked there were multiboot1/2 modules passed - renmaed struct elements per the review - fixed errant commit messages per the review - corrected coding style per review - attempted to repalce all open codings of page/addr translations touched - unified use of `bi` as var name for pointer ref to struct boot_info - when appropriate, ensure variables where typed, eg size_t, paddr_t, etc. - dropped all uses of "a = b = c" Changes since v3: - reduced scope to x86 only - broke changes into a smaller chunks with a linear progression - concerns about deconflicting with Arm deferred - conversion from mb1 to boot modules no longer attempted at entry points - the temporary conversion function is now the permenant means to convert - incorporated suggestion from Andy Cooper for handling bootstrap_map Changes since v2: - combined v2 patches 7 and 8 for common review - rebased the v2 series onto the current tip of staging (sorry) - fixed the placement of the patch changelogs - provided the changes description in the cover letter Changes since v1: - the v2 and v3 series implement functionality from v1 patches 2-4 - v2 series objective is to enable efficient patch review in support of merging the functionality into the hypervisor. It implements a subset of the v1 series, incorporating changes from community feedback. - the bootstrap map is made accessible early in the v2 series via both multiboot and boot module arguments until later in the series where multiboot use is retired. This allows for incremental conversion across several patches from multiboot to boot modules. - the 32-bit x86 boot environment header is removed, and changes are made to allow the new common bootinfo headers to be used instead. - Arm and RISC-V architecture bootinfo headers are added to ensure that builds on those architectures can complete correctly. - The KConfig patch to set the maximum number of boot modules allowed is not included in this series, replaced with a static maximum define.
