Berrang=C3=A9 --- We last considered this back in 2018, but in the end both QEMU and the kernel gave the port a stay of execution; the maintenance situation doesn't seem to have improved, and now the kernel has dropped support and especially given the lack of a toolchain I think it's time to start the deprecation process here. --- docs/system/deprecated.rst | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/docs/system/deprecated.rst b/docs/system/deprecated.rst index 851dbdeb8ab..4c52098c707 100644 --- a/docs/system/deprecated.rst +++ b/docs/system/deprecated.rst @@ -416,6 +416,14 @@ The above, converted to the current supported format:: linux-user mode CPUs -------------------- =20 +``unicore32`` CPUs (since 5.2.0) +'''''''''''''''''''''''''''''''' + +The ``unicore32`` guest CPU support is deprecated and will be removed in +a future version of QEMU.
