xen: drop 32-bit ARM from COMPATIBLE_HOST

2026-05-29T20:26:17+00:00

Xen on ARM requires ARMv8 hardware virtualization extensions, which are only available on AArch64 (64-bit). The 32-bit ARM entry in COMPATIBLE_HOST was a leftover from early ARM Xen experimentation that upstream effectively abandoned. This becomes a build failure now that QEMU has dropped support for building on 32-bit hosts — the qemu-system-i386 package that xen-tools RDEPENDS on for HVM device emulation is no longer buildable for arm-poky-linux-gnueabi targets, making the entire xen-image-minimal unbuildable on 32-bit ARM.

xen: fix buildpaths QA errors for hypervisor EFI and debug packages

2026-05-12T12:52:48+00:00

Xen's hypervisor Makefile overrides CFLAGS entirely with its own flags (nostdinc, fno-builtin, etc.), so OE's DEBUG_PREFIX_MAP flags added via CFLAGS never reach the hypervisor compilation. The existing prefix map entries in xen.inc appeared to work only because sstate was caching pre-built packages — a fresh rebuild exposes the embedded TMPDIR paths in the EFI binary and debug symbols. Inject the prefix maps through EXTRA_CFLAGS_XEN_CORE, which is Xen's own mechanism for accepting additional compiler flags and is already passed through to oe_runmake. This fixes the EFI binary paths. The xen-syms debug binary retains one source path in .debug_str from the linker/assembly stage, which does not honor the C compiler's -fdebug-prefix-map. Since xen-syms is only shipped in the -dbg package (not a deployment target), skip buildpaths for xen-dbg. This is an optional QA test — not in CHECKLAYER_REQUIRED_TESTS — so it has no impact on yocto-check-layer compatibility. Signed-off-by: Bruce Ashfield

vgabios: remove recipe, drop from xen-tools DEPENDS

2026-03-24T17:56:14+00:00

vgabios 0.8a depends on dev86-native which was removed in a previous commit (upstream repo deleted). vgabios is a legacy VGA BIOS from 2008 that has been superseded by SeaBIOS which is already a Xen dependency. Signed-off-by: Bruce Ashfield

xen: drop dev86 dependency and disable rombios

2026-03-24T12:24:49+00:00

dev86 (as86/ld86/bcc) was only needed to build rombios, the legacy BIOS for HVM guests. The upstream repository (jbruchon/dev86) has been deleted from GitHub. SeaBIOS is already in DEPENDS and is the modern replacement — no Xen HVM guest uses rombios in practice. Disable rombios explicitly and remove the dev86-native dependency.
