Subject: [PULL 19/24] i386: adjust the expected KVM_GET_SUPPORTED_HV_CPUID array size
Date: Tue,  1 Jun 2021 14:10:09 -0400	[thread overview]
Message-ID: <20210601181014.2568861-20-ehabkost@redhat.com> (raw)
In-Reply-To: <20210601181014.2568861-1-ehabkost@redhat.com>

From: Vitaly Kuznetsov <vkuznets@redhat.com>

SYNDBG leaves were recently (Linux-5.8) added to KVM but we haven't
updated the expected size of KVM_GET_SUPPORTED_HV_CPUID output in
KVM so we now make serveral tries before succeeding. Update the
default.
