Hello Harsh, On 9/17/24 08:03, Harsh Prateek Bora wrote: > Commit 1392617d3576 intended to tag pseries-2.1 - 2.11 machines as > deprecated with reasons mentioned in its commit log. > Removing the arch specific code for the now deprecated machine types. > > Suggested-by: Cédric Le Goater <clg@kaod.org> > Signed-off-by: Harsh Prateek Bora <harshpb@linux.ibm.com> There is more to it :/ Some machine versions have their own set of properties, like the "pre-*-migration" ones, and the associated code should be removed also. It impacts more models than just the machine model. I suggest one patch per machine version, or one patch per complex machine version and a combo patch for the simple ones.
