+''''''''''''''''''''''''''''
+
+The ``--enable-gprof`` configure setting relies on compiler
+instrumentation to gather its data which can distort the generated
+profile. As other non-instrumenting tools are available that give a
+more holistic view of the system with non-instrumented binaries we are
+deprecating the build option and no longer defend it in CI. The
+``--enable-gcov`` build option remains for analysis test case

 Note this also applies to ``-device virtio-blk-pci,scsi=on|off``, which is an

-``-device sga`` (since 6.2)
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The ``sga`` device loads an option ROM for x86 targets which enables
-SeaBIOS to send messages to the serial console. SeaBIOS 1.11.0 onwards
-contains native support for this feature and thus use of the option
-ROM approach is obsolete. The native SeaBIOS support can be activated
-by using ``-machine graphics=off``.
