| 5 | # Minimal QEMU variant for vcontainer tools (vdkr/vpdmn) | ||
| 6 | # | ||
| 7 | # This recipe provides a stripped-down nativesdk QEMU without OpenGL/SDL | ||
| 8 | # dependencies, avoiding the mesa -> llvm -> clang build chain. | ||
| 9 | # | ||
| 10 | # This is separate from the main nativesdk-qemu to avoid affecting other | ||
| 11 | # users who may need OpenGL support in their SDK QEMU. | ||
| 12 | # | ||
| 13 | # VERSION TRACKING: This recipe automatically discovers the QEMU version | ||
| 14 | # from oe-core, so no updates are needed when oe-core bumps QEMU. | ||
| 15 | |||
