The patch adds in/out instructions to the x86 emulator. The instruction was encountered while running the BIOS while using the invalid guest state emulation patch. Signed-off-by: NMohammed Gamal <m.gamal005@gmail.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>

EPT is 4 level by default in 32pae(48 bits), but the addr parameter of kvm_shadow_walk->entry() only accept unsigned long as virtual address, which is 32bit in 32pae. This result in SHADOW_PT_INDEX() overflow when try to fetch level 4 index. Fix it by extend kvm_shadow_walk->entry() to accept 64bit addr in parameter.

Heiko Carstens pointed out, that its safer to activate working facilities instead of disabling problematic facilities. The new code uses the host facility bits and masks it with known good ones.

Currently KVM implements MC0-MC4_MISC read support. When booting Linux this results in KVM warnings in the kernel log when the guest tries to read MC5_MISC. Fix this warnings with this patch. Signed-off-by: NJoerg Roedel <joerg.roedel@amd.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>

The accessed bit was accidentally turned on in a random flag word, rather than, the spte itself, which was lucky, since it used the non-EPT compatible PT_ACCESSED_MASK. Fix by turning the bit on in the spte and changing it to use the portable accessed mask. Signed-off-by: NAvi Kivity <avi@qumranet.com>

Otherwise, the cpu may allow writes to the tracked pages, and we lose some display bits or fail to migrate correctly. Signed-off-by: NAvi Kivity <avi@qumranet.com>

This is esoteric and only needed to break COW on MAP_SHARED mappings. Since KVM no longer does these sorts of mappings, breaking COW on them is no longer necessary. Signed-off-by: NAvi Kivity <avi@qumranet.com>

We currently walk the shadow page tables in two places: direct map (for real mode and two dimensional paging) and paging mode shadow. Since we anticipate requiring a third walk (for invlpg), it makes sense to have a generic facility for shadow walk. This patch adds such a shadow walker, walks the page tables and calls a method for every spte encountered. The method can examine the spte, modify it, or even instantiate it. The walk can be aborted by returning nonzero from the method. Signed-off-by: NAvi Kivity <avi@qumranet.com>

Even though we don't share irqs at the moment, we should ensure regular user processes don't try to allocate system resources. We check for capability to access IO devices (CAP_SYS_RAWIO) before we request_irq on behalf of the guest. Noticed by Avi.

The irq ack during pic reset has three problems: - Ignores slave/master PIC, using gsi 0-8 for both. - Generates an ACK even if the APIC is in control. - Depends upon IMR being clear, which is broken if the irq was masked at the time it was generated. The last one causes the BIOS to hang after the first reboot of Windows installation, since PIT interrupts stop.
