0.28.0: i686-linux-musl, x86_64-uefi, i686-openkal and i686-dos-musl (technical experiment); the family on openkal 0.25.3 - #31
Merged
Conversation
…enkal 0.25.1 The hosted arrangement serves i686-linux-musl: openkal-musl 0.29.5 over openkal-linux 0.26.3's i386 system-call layer, with openkal-llvm-runtime 0.20.2 above it. CI builds and runs the hosted program on Linux x86_64 and runs the specification's conformance suite through the platform over openkal-linux at the group's version. The group follows openkal 0.25.1; its implementations declare the specification by its minor version (openkal-macos 0.23.2, openkal-windows 0.21.2, openkal-freebsd 0.1.2; openkal-image 0.6.2).
…does The released mcpp registers i686-linux-musl as planned and takes the row when the toolchain is named; the conformance step named none and was refused.

…e console; the UEFI machine has 2 GiB The runner's hosts include uefi-x86_64, so a single-file pack for that system builds the carrier as an application of the x86_64-uefi row. The board defines okuefi_board_errors_to_console (OVMF's StdErr reaches no serial reader). dirun boots the row with 2 GiB: the carrier's allocator and the image's each place an arena at a 256 MiB alignment, which 512 MiB did not hold twice. Measured: a carried image that prints, writes to standard error, throws and catches returned status 7 under OVMF in 0.4 s.
…openkal-dos; the seal okdos
…s on the i386 rows The platform serves i686-openkal (openkal 0.25.1, clauses 5.5 and 12.2; openkal-image 0.6.3 loads it). The ok images' link states its addends (`-z rela`), which is i386's one difference from the linker's default. The row is compiled for the Pentium (`-march=i586`) with the stack aligned to sixteen bytes at a call (`-mstack-alignment=16`), the System V i386 convention SPEC 12.2 states; a triple with no system leaves clang at four, and okrun's code, built for Linux, faulted on a `movaps` when such an image called it (measured). The DOS row takes the same alignment: its code calls images and is called by them. The README states the row, how a project selects it while mcpp names it planned, and what openkal-dos's files give a DOS program.
…dos-i686) DOSBox Staging 0.83 executes RDTSC and not CMPXCHG8B under every cputype (measured), and an image's sixty-four bit atomics (mimalloc's statistics) were that instruction under -march=i586, so i686-openkal and i686-dos-musl are compiled for the 486 and such an atomic is compiler-rt's call. The runner's hosts include dos-i686: the core runner as a program of the DOS row, which mcpp 2026.11.13.1 builds as the row the platform defines for the system. Measured: an i686-openkal image packed so ran under DOSBox Staging and returned 7.
checks/i386 builds an i686-openkal image in both modes, checks it with okld and runs it with okrun built for i686-linux-musl from the openkal-image release the group names; packed with --systems dos-i686, the image runs as a DOS program under DOSBox Staging. checks/dos runs a program of i686-dos-musl in both modes through the provider's runner. Both return status 7.
…nkal-dos's tag The family release checks its tag, mirror and index entry as it checks openkal-tools'. The README's statement table names i686-openkal and okdos.

openkal-platform 0.28.0 adds four rows and moves the family to openkal 0.25.3.
Rows
i686-linux-musl, the hosted arrangement's thirty-two bit Linux row (openkal 0.25.1, clause 5.5). It is openkal-musl over openkal-linux 0.26.3's i386 system-call layer, with openkal-llvm-runtime above it.x86_64-uefi, UEFI applications over openkal-uefi 0.10.0. The row is PE32+ with the EFI application subsystem, and its runner is dirun with xim's OVMF under QEMU q35. An ok image also packs for UEFI as a carried program (uefi-x86_64). The board makes standard error the console, and the UEFI machine has 2 GiB.i686-openkal, the ok image of i386. The image is ELF32 with REL relocations, linked with-z rela.i686-dos-musl, DOS programs.
