* x86/xsave: fix migration from xsave-capable to xsave-incapable hostJan Beulich2013-09-091-9/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With CPUID features suitably masked this is supposed to work, but was completely broken (i.e. the case wasn't even considered when the original xsave save/restore code was written). First of all, xsave_enabled() wrongly returned the value of cpu_has_xsave, i.e. not even taking into consideration attributes of the vCPU in question. Instead this function ought to check whether the guest ever enabled xsave support (by writing a [non-zero] value to XCR0). As a result of this, a vCPU's xcr0 and xcr0_accum must no longer be initialized to XSTATE_FP_SSE (since that's a valid value a guest could write to XCR0), and the xsave/xrstor as well as the context switch code need to suitably account for this (by always enforcing at least this part of the state to be saved/loaded). This involves undoing large parts of c/s 22945:13a7d1f7f62c ("x86: add strictly sanity check for XSAVE/XRSTOR") - we need to cleanly distinguish between hardware capabilities and vCPU used features. Next both HVM and PV save code needed tweaking to not always save the full state supported by the underlying hardware, but just the parts that the guest actually used. Similarly the restore code should bail not just on state being restored that the hardware cannot handle, but also on inconsistent save state (inconsistent XCR0 settings or size of saved state not in line with XCR0). And finally the PV extended context get/set code needs to use slightly different logic than the HVM one, as here we can't just key off of xsave_enabled() (i.e. avoid doing anything if a guest doesn't use xsave) because the tools use this function to determine host capabilities as well as read/write vCPU state. The set operation in particular needs to be capable of cleanly dealing with input that consists of only the xcr0 and xcr0_accum values (if they're both zero then no further data is required). While for things to work correctly both sides (saving _and_ restoring host) need to run with the fixed code, afaict no breakage should occur if either side isn't up to date (other than the breakage that this patch attempts to fix).

| | | | | | | | | | | Defer the FIP/FDP pointer reset needed on AMD CPUs to the restore path, and switch from using EMMS to FFREE here too (to be resistant against eventual future CPUs without MMX support). Also switch from using an almost typeless pointer in fpu_fxrstor() to a properly typed one, thus telling the compiler the truth about which memory gets accessed.

* x86: preserve FPU selectors for 32-bit guest codeJan Beulich2013-06-041-32/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Doing {,F}X{SAVE,RSTOR} unconditionally with 64-bit operand size leads to the selector values associated with the last instruction/data pointers getting lost. This, besides being inconsistent and not compatible with native hardware behavior especially for 32-bit guests, leads to bug checks in 32-bit Windows when running with "Driver verifier" (see e.g. http://support.microsoft.com/kb/244617). In a first try I made the code figure out the current guest mode, but that has the disadvantage of only taking care of the issue when the guest executes in the mode for which the state currently is (i.e. namely not in the case of a 64-bit guest running a 32-bit application, but being in kernle [64-bit] mode). The solution presented here is to conditionally execute an auxiliary FNSTENV and use the selectors from there. In either case the determined word size gets stored in the last byte of the FPU/SSE save area, which is available for software use (and I verified is being cleared to zero by all versions of Xen, i.e. will not present a problem when migrating guests from older to newer hosts), and evaluated for determining the operand size {,F}XRSTOR is to be issued with. Note that I did check whether using a second FXSAVE or a partial second XSAVE would be faster than FNSTENV - neither on my Westmere (FXSAVE) nor on my Romley (XSAVE) they are. I was really tempted to use branches into the middle of instructions (i.e. past the REX64 prefixes) here, as that would have allowed to collapse the otherwise identical fault recovery blocks. I stayed away from doing so just because I expect others to dislike such slightly subtle/tricky code.

* x86/xsave: recover from faults on XRSTORJan Beulich2013-06-041-1/+1
| | | | | | | | | | | | | | Just like FXRSTOR, XRSTOR can raise #GP if bad content is being passed to it in the memory block (i.e. aspects not under the control of the hypervisor, other than e.g. proper alignment of the block). Also correct the comment explaining why FXRSTOR needs exception recovery code to not wrongly state that this can only be a result of the control tools passing a bad image.

* x86/xsave: provide guests with finit-like environmentJan Beulich2011-11-181-1/+0
| | | | | | | | | | | | | | | | | | | Without the use of xsave, guests get their initial floating point environment set up with finit. At least NetWare actually depends on this (in particular on all exceptions being masked), so to be consistent set the same environment also when using xsave. This is also in line with all SSE exceptions getting masked initially. To avoid further fragile casts in xstate_alloc_save_area() the patch also changes xsave_struct's fpu_see member to have actually usable fields. The patch was tested in its technically identical, but modified-file- wise different 4.1.2 version.

* x86/fpu: create lazy and non-lazy FPU restore functionsWei Huang2011-05-091-5/+20
| | | | | | | | | | | | | Currently Xen relies on #NM (via CR0.TS) to trigger FPU context restore. But not all FPU state is tracked by TS bit. This function creates two FPU restore functions: vcpu_restore_fpu_lazy() and vcpu_restore_fpu_eager(). vcpu_restore_fpu_lazy() is still used when #NM is triggered. vcpu_restore_fpu_eager(), as a comparision, is called for vcpu which is being scheduled in on every context switch. To minimize restore overhead, it creates a flag, nonlazy_xstate_used, to control non-lazy restore. Signed-off-by: Wei Huang <wei.huang2@amd.com>

* x86: split struct vcpuJan Beulich2011-04-051-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | This is accomplished by splitting the guest_context member, which by itself is larger than a page on x86-64. Quite a number of fields of this structure is completely meaningless for HVM guests, and thus a new struct pv_vcpu gets introduced, which is being overlaid with struct hvm_vcpu in struct arch_vcpu. The one member that is mostly responsible for the large size is trap_ctxt, which now gets allocated separately (unless fitting on the same page as struct arch_vcpu, as is currently the case for x86-32), and only for non-hvm, non-idle domains. This change pointed out a latent problem in arch_set_info_guest(), which is permitted to be called on already initialized vCPU-s, but so far copied the new state into struct arch_vcpu without (in this case) actually going through all the necessary accounting/validation steps. The logic gets changed so that the pieces that bypass accounting will at least be verified to be no different from the currently active bits, and the whole change will fail in case they are. The logic does *not* get adjusted here to do full error recovery, that is, partially modified state continues to not get unrolled in case of failure. Signed-off-by: Jan Beulich <jbeulich@novell.com>

* x86: Avoid calling xsave_alloc_save_area before xsave_initKeir Fraser2011-01-141-2/+42
| | | | | | | | | | | | | | | Currently, xsave_alloc_save_area will be called in init_idle_domain->scheduler_init->alloc_vcpu->vcpu_initialise calls with xsave_cntxt_size=0, it is earlier than xsave_init called in identity_cpu(). This may causing buffer overflow on xmem_pool. Idle domain isn't using FPU,SSE,AVX or any such extended state and doesn't need it saved. xsave_{alloc,free}_save_area() should test-and-exit on is_idle_vcpu(), and our context switch code should not be doing XSAVE when switching out an idle vcpu.

| | | | | | | | | Rationalise x86 CRn guest state into a ctrlreg array in the per-vcpu context structure. Most noticeably this means the pt_base field has gone away -- replaced by ctrlreg[3] (CR3). VCPU_guest_stts is also gone -- it was never arch-independent anyway. Signed-off-by: Keir Fraser <keir@xensource.com>

| | | | | | | | | More descriptive 'flags' and 'id' field names for exec_domain/domain structures seems a good idea after all. At the same time, I've renamed the flag macros to be a bit neater and more descriptive, and more in keeping with the style of such definitions in asm/mm.h, for example.
