vmx/hap: optimize CR4 trapping
There a bunch of bits in CR4 that should be allowed to be set directly
by the guest without requiring Xen intervention, currently this is
already done by passing through guest writes into the CR4 used when
running in non-root mode, but taking an expensive vmexit in order to
do so.
xenalyze reports the following when running a PV guest in shim mode:
CR_ACCESS 3885950 6.41s 17.04% 3957 cyc { 2361| 3378| 7920}
cr4 3885940 6.41s 17.04% 3957 cyc { 2361| 3378| 7920}
cr3 1 0.00s 0.00% 3480 cyc { 3480| 3480| 3480}
*[ 0] 1 0.00s 0.00% 3480 cyc { 3480| 3480| 3480}
cr0 7 0.00s 0.00% 7112 cyc { 3248| 5960|17480}
clts 2 0.00s 0.00% 4588 cyc { 3456| 5720| 5720}
After this change this turns into:
CR_ACCESS 12 0.00s 0.00% 9972 cyc { 3680|11024|24032}
cr4 2 0.00s 0.00% 17528 cyc {11024|24032|24032}
cr3 1 0.00s 0.00% 3680 cyc { 3680| 3680| 3680}
*[ 0] 1 0.00s 0.00% 3680 cyc { 3680| 3680| 3680}
cr0 7 0.00s 0.00% 9209 cyc { 4184| 7848|17488}
clts 2 0.00s 0.00% 8232 cyc { 5352|11112|11112}
Note that this optimized trapping is currently only applied to guests
running with HAP on Intel hardware. If using shadow paging more CR4
bits need to be unconditionally trapped, which makes this approach
unlikely to yield any important performance improvements.

There a bunch of bits in CR4 that should be allowed to be set directly

already done by passing through guest writes into the CR4 used when

clts 2 0.00s 0.00% 4588 cyc { 3456| 5720| 5720}
After this change this turns into:
CR_ACCESS 12 0.00s 0.00% 9972 cyc { 3680|11024|24032}
cr4 2 0.00s 0.00% 17528 cyc {11024|24032|24032}
cr3 1 0.00s 0.00% 3680 cyc { 3680| 3680| 3680}
*[ 0] 1 0.00s 0.00% 3680 cyc { 3680| 3680| 3680}
cr0 7 0.00s 0.00% 9209 cyc { 4184| 7848|17488}
clts 2 0.00s 0.00% 8232 cyc { 5352|11112|11112}
Note that this optimized trapping is currently only applied to guests
running with HAP on Intel hardware. If using shadow paging more CR4
bits need to be unconditionally trapped, which makes this approach
unlikely to yield any important performance improvements.

commit c52319642bb9069436d4aec75361049f5fac63ed
Author: Andrew Cooper <andrew.cooper3@citrix.com>

x86/cpuid: Calculate a guests xfeature_mask from its featureset
libxc current performs the xstate calculation for guests, and provides the
information to Xen to be used when satisfying CPUID traps. (There is further
work planned to improve this arrangement, but the worst a buggy toolstack can
do is make junk appear in the cpuid leaves for the guest.)
dom0 however has no policy constructed for it, and certain fields filter
straight through from hardware.
Linux queries CPUID.7[0].{EAX/EDX} alone to choose a setting for %xcr0, which
is a valid action to take, but features such as MPX and PKRU are not supported
for PV guests. As a result, Linux, using leaked hardware information, fails
to set %xcr0 on newer Skylake hardware with PKRU support, and crashes.
As an interim solution, dynamically calculate the correct xfeature_mask and
xstate_size to report to the guest for CPUID.7[0] queries. This ensures that
domains don't see leaked hardware values, even when no cpuid policy is
provided.
Similarly, CPUID.7[1]{ECX/EDX} represents the applicable settings for MSR_XSS.
As Xen doesn't yet support any XSS states in guests, unconditionally zero
them.

x86/cpuid: Calculate a guests xfeature_mask from its featureset
libxc current performs the xstate calculation for guests, and provides the
information to Xen to be used when satisfying CPUID traps. (There is further
work planned to improve this arrangement, but the worst a buggy toolstack can
do is make junk appear in the cpuid leaves for the guest.)
dom0 however has no policy constructed for it, and certain fields filter
straight through from hardware.
Linux queries CPUID.7[0].{EAX/EDX} alone to choose a setting for %xcr0, which
is a valid action to take, but features such as MPX and PKRU are not supported
for PV guests. As a result, Linux, using leaked hardware information, fails
to set %xcr0 on newer Skylake hardware with PKRU support, and crashes.
As an interim solution, dynamically calculate the correct xfeature_mask and
xstate_size to report to the guest for CPUID.7[0] queries. This ensures that
domains don't see leaked hardware values, even when no cpuid policy is
provided.
Similarly, CPUID.7[1]{ECX/EDX} represents the applicable settings for MSR_XSS.
As Xen doesn't yet support any XSS states in guests, unconditionally zero
them.
