[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH RFC tools 1/6] tools: Refactor "xentoollog" into its own library
In attempting to disaggregate libxenctrl I found that many of the
pieces were going to want access to this library, so split it out (as
it probably should always have been).
Various build adjustments are needed. In particular things which use
xtl_* themselves now need to explicity link against the library.
This has a nice side effect which is that users of libxl no longer
need to link against libxenctrl just to create a logger.
The new library uses a version script to ensure that only expected
symbols are exported and to version them such that ABI guarantees can
be kept in the future.
Signed-off-by: Ian Campbell <ian.campbell@xxxxxxxxxx>

Must be applied with:
- "qemu-xen-traditional: Use xentoollog as a separate library" and a
corresponding QEMU_TAG update folded here.
- "mini-os: Include libxentoollog with libxc" and a corresponding bump
to MINIOS_UPSTREAM_REVISION folded in here.
