Two things needed fixing: 1) g++ does not allow a named structure type within an anonymous union and 2) Avoid name clash between two padding fields within the same struct by giving them different names as is done elsewhere in the header. Signed-off-by:

Commit 46ee278652f4cbd51013471b64c7897ba9bcd1b1 causes Solaris 10 to hang on boot. Assuming that PIT counter reads should return 0 for an expired timer is wrong: when it is active, the counter never stops (see comment on __kpit_elapsed). Also arm a one shot timer for mode 0. Signed-off-by:

1. It's related to a Linux kernel bug which fixed by Ingo on 07a66d7c. The original code exists for quite a long time, and it would convert a PDE for large page into a normal PDE. But it fail to fit normal PDE well. With the code before Ingo's fix, the kernel would fall reserved bit checking with bit 8 - the remaining global bit of PTE. So the kernel would receive a double-fault. 2. After discussion, we decide to discard PDE bit 7-8 reserved checking for now. For this marked as reserved in SDM, but didn't checked by the processor in fact... Signed-off-by:

There is no need to skip instruction if the reason for a task switch is a task gate in IDT and access to it is caused by an external even. The problem is currently solved only for VMX since there is no reliable way to skip an instruction in SVM. We should emulate it instead. Signed-off-by:

We will need it later in task_switch(). Code in handle_exception() is dead. is_external_interrupt(vect_info) will always be false since idt_vectoring_info is zeroed in vmx_complete_interrupts(). Signed-off-by:

...with a more straightforward switch(). Also fix a bug when NMI could be dropped on exit. Although this should never happen in practice, since NMIs can only be injected, never triggered internally by the guest like exceptions. Signed-off-by:

A pte that is shadowed when the guest EFER.NXE=1 is not valid when EFER.NXE=0; if bit 63 is set, the pte should cause a fault, and since the shadow EFER always has NX enabled, this won't happen. Fix by using a different shadow page table for different EFER.NXE bits. This allows vcpus to run correctly with different values of EFER.NXE, and for transitions on this bit to be handled correctly without requiring a full flush. Signed-off-by: -

Detect, indicate, and propagate page faults where reserved bits are set. Take care to handle the different paging modes, each of which has different sets of reserved bits. [avi: fix pte reserved bits for efer.nxe=0] Signed-off-by:

Currently, the interrupt enable bit is cleared when in the vmm. This patch sets the bit and the external interrupts can be dealt with when in the vmm. This improves the I/O performance. Signed-off-by:

Currently timer events are processed before entering guest mode. Move it to main vcpu event loop since timer events should be processed even while vcpu is halted. Timer may cause interrupt/nmi to be injected and only then vcpu will be unhalted. Signed-off-by:
