commit 18c128ba66e6308744850aca96dbffd18f91c29b
Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>

    x86/hvm: Disallow disabling paging in 64bit mode
    
    The Long Mode consistency checks exist to "ensure that the processor does 
not
    enter an undefined mode or state that results in unpredictable behavior".  
APM
    Vol2 Table 14-5 "Long-Mode Consistency Checks" lists them, but there is no 
row
    preventing the OS from trying to exit Long mode while in 64bit mode.  This
    could leave the CPU in Protected Mode with an %rip above the 4G boundary.
    
    Experimentally, AMD CPUs really do permit this state transition.  An OS 
which
    tries it hits an instant SHUTDOWN, even in cases where the truncation I 
expect
    to be going on behind the scenes ought to result in sane continued 
execution.
    
    Furthermore, right from the very outset, the APM Vol2 14.7 "Leaving Long 
Mode"
    section instructs peoples to switch to a compatibility mode segment first
    before clearing CR0.PG, which does clear out the upper bits in %rip.  This 
is
    further backed up by Vol2 Figure 1-6 "Operating Modes of the AMD64
    Architecture".
    
    Either way, this appears to have been a genuine oversight in the AMD64 spec.
    
    Intel, on the other hand, rejects this state transition with #GP.
    
    Between revision 71 (Nov 2019) and 72 (May 2020) of SDM Vol3, a footnote to
    4.1.2 "Paging-Mode Enable" was altered from
    
      If CR4.PCIDE= 1, an attempt to clear CR0.PG causes a general-protection
      exception (#GP); software should clear CR4.PCIDE before attempting to
      disable paging.
    
    to
    
      If the logical processor is in 64-bit mode or if CR4.PCIDE= 1, an attempt 
to
      clear CR0.PG causes a general-protection exception (#GP). Software should
      transition to compatibility mode and clear CR4.PCIDE before attempting to
      disable paging.
    
    which acknowledges this corner case, but there doesn't appear to be any 
other
    discussion even in the relevant Long Mode sections.
    
    So it appears that Intel spotted and addressed the corner case in IA-32e 
mode,
    but were 15 years late to document it.
    
    Xen was written to the AMD spec, and misses the check.  Follow the Intel
    behaviour, because it is more sensible and avoids hitting a VMEntry failure.

    automation: switch ADL hw tests to debug build
    
    This should give a lot more useful information in case of a failure, and
    also enable some asserts for extra checks.
