... as being intended to be faster than MSR reads/writes.
In the case of emulate_privileged_op() also use these in favor of the
cached (but possibly stale) addresses from arch.pv_vcpu. This allows
entirely removing the code that was the subject of XSA-67.

... thus allowing to make the entries half their current size. Rather
than adjusting all instances to the new layout, abstract the
construction the table entries via a macro (paralleling a similar one
in recent Linux).
Also change the name of the section (to allow easier detection of
missed cases) and merge the final resulting output sections into
.data.read_mostly.

In the warning message issued on writes, the Xen-modified value should
be printed (and used to determine whether anything needs to be printed
at all), as the guest kernel will usually do a read-modify-write
cycle.
A question is whether Dom0 shouldn't be allowed control over some
bits, or whether some bits shouldn't be fully virtualized. I'm
particularly thinking of MSR_IA32_MISC_ENABLE_FAST_STRING, which
recent Linux kernels want to disable for CONFIG_KMEMCHECK.
While putting this together I also noticed that rdmsr_safe() failed to
initialize its output registers in the failure path, thus leading to
printing of uninitialized data in the guest WRMSR warning message.
Further, the default case value-changed check can be simplified.

(NOTE: pvrdtscp mode not finished yet, but all other
modes have been tested so sooner seemed better than
later to submit this fairly major patch so we can get
more mileage on it before next release.)
New tsc_mode config option supercedes tsc_native and
offers a more intelligent default and an additional
option for intelligent apps running on PV domains
("pvrdtscp").
For PV domains, default mode will determine if the initial
host has a "safe"** TSC (meaning it is always synchronized
across all physical CPUs). If so, all domains will
execute all rdtsc instructions natively; if not,
all domains will emulate all rdtsc instructions but
providing the TSC hertz rate of the initial machine.
After being restored or live-migrated, all PV domains will
emulate all rdtsc instructions. Hence, this default mode
guarantees correctness while providing native performance
in most conditions.
For PV domains, tsc_mode==1 will always emulate rdtsc
and tsc_mode==2 will never emulate rdtsc. For tsc_mode==3,
rdtsc will never be emulated, but information is provided
through pvcpuid instructions and rdtscp instructions
so that an app can obtain "safe" pvclock-like TSC information
across save/restore and live migration. (Will be completed in
a follow-on patch.)
For HVM domains, the default mode and "always emulate"
mode do the same as tsc_native==0; the other two modes
do the same as tsc_native==1. (HVM domains since 3.4
have implemented a tsc_mode=default-like functionality,
but also can preserve native TSC across save/restore
and live-migration IFF the initial and target machines
have a common TSC cycle rate.)
** All newer AMD machines, and Nehalem and future Intel
machines have "Invariant TSC"; many newer Intel machines
have "Constant TSC" and do not support deep-C sleep states;
these and all single-processor machines are "safe".

While working on TSC-handling code, I missed an important
piece of code that writes to TSC because it does it
differently than other pieces of code. Fix that,
and also cleanup a bit to avoid hardcoded constants
and use wrmsrl instead of wrmsr plus handwritten 64-bit
dismembering code.

Linux, under CONFIG_SECCOMP, has been capable of hiding the TSC from
processes for quite a while. This patch enables this to actually work
for pv kernels, by allowing them to control CR4.TSD (and, as a simple
thing to do at the same time, CR4.DE).
Applies cleanly only on top of the previously submitted debug register
handling patch.

The Intel processor driver for Windows (XP and later at least) reads
an MSR that AMD doesn't have. This causes GP-fault in kernel mode,
which causes blue-screen-of-death on Windows. This prevents a
disk-image that was installed on Intel from starting on an AMD
processor.
This patch "fixes" the problem by allowing reads from the msr,
returning all zero's (which is a valid, if not particulary
meaningful, value for this register).

Some operating systems access the local APIC TPR very frequently, and
we handle that using software-based local APIC virtualization in Xen
today. Such virtualization incurs a number of VM exits from the
memory-access instructions against the APIC page in the guest.
The attached patch enables the TPR shadow feature that provides APIC
TPR virtualization in hardware. Our tests indicate it can
significantly boost the performance of such guests including 32-bit
Windows XP/2003.
Moreover, with the patch, local APIC accesses other than TPR in guests
are intercepted directly as APIC_ACCESS VM exits rather than
PAGE_FAULT VM exits; this can lower the emulation cost of such
accesses.

The threshold register has been introduced in AMD RevF CPUs along with
SVM (Actually this MCA/MCE msr register existed before, but had no
meaning). Therefore no need for additional cpuid checks.
On read access it reports the HVM guest the register has been locked
by the BIOS. This means, it is not available for OS use. Thus, write
accesses are simply ignored. This behaviour actually matches real HW,
so guests can deal with this.

Introduce a per-CPU shadow of what is currently in EFER, as context
switch code must re-write this MSR so that all guests run with
appropriate EFER.SCE and EFER.NX settings. Remove EFER from the set of
MSRs that VMX deals with in a generic fashion.

a patch to improve the VMCS control bits setting. It also adds checks to
detect any non-optimal or incompatible settings for the VMCS control
bits based on MSRs, and fixes a bug associated with vmcs region freeing.

x86_64 specific MSRs at domain switch time if modified. In VMX domains,
we modify those upon requests from the guests to that end. Note that
IA32_EFER.LME and IA32_EFER.LMA are saved/restored by H/W on every VM
exit. For the usual domains (i.e. dom0 and domU), those MSRs are not
modified once set at initialization time, so we don't save them when
swiched out, but simply reset them (if modified) to the initial values
when switched in. This patch also include extended handling for 64-bit
guests. Please apply.

Change priv-op emulation behaviour to fail silently in some cases
rather than propagate the fault (still non-silent in debug builds!).
Also be careful in running user-specified RDMSR/WRMSR: an invalid
MSR index causes a GP(0) fault.

More x86_64 stuff. Added hypercalls to register a user-space pagetable,
modify FS/GS base addresses, and switch to user mode. User mode switches
back to kernel mode automatically on executing SYSCALL instruction.
Still todo: 1. getdomaininfo needs to include pagetable_user
2. get writable and shadow pagetables working
3. testing

Towards x86_64 support. Merged a bunch of the existing x86_64 stuff
back into a generic 'x86' architecture. Aim is to share as much
as possible between 32- and 64-bit worlds.
