From 375c4837ee10d481254e8910b873a6ce03cfd742 Mon Sep 17 00:00:00 2001 From: Jason Andryuk Date: Wed, 16 Apr 2025 17:29:09 -0400 Subject: [PATCH] tools/init-dom0less: Only seed legacy xenstore grants The hardware domain is unable to seed a control domain, but we want the control domain to use xenstore. Rely on the hypervisor to seed dom0less grant table entries for Xenstore, so this seeding is unnecessary. However, that only works for the new xenstore late init. The legacy protocol which uses init-dom0less to populate the page still needs to seed the grant.
