Subject: [PULL v4 01/43] target/i386: add missing bits to CR4_RESERVED_MASK
Date: Wed, 8 Sep 2021 12:03:44 +0200 [thread overview]
Message-ID: <20210908100426.264356-2-pbonzini@redhat.com> (raw)
In-Reply-To: <20210908100426.264356-1-pbonzini@redhat.com>
From: Daniel P. Berrangé <berrange@redhat.com>
Booting Fedora kernels with -cpu max hangs very early in boot. Disabling
the la57 CPUID bit fixes the problem. git bisect traced the regression to
commit 213ff024a2f92020290296cb9dc29c2af3d4a221 (HEAD, refs/bisect/bad)

target/i386: Added consistency checks for CR4
All MBZ bits in CR4 must be zero. (APM2 15.5)
Added reserved bitmask and added checks in both
helper_vmrun and helper_write_crN.

In this commit CR4_RESERVED_MASK is missing CR4_LA57_MASK and
two others. Adding this lets Fedora kernels boot once again.
