2011-07-24KVM: MMU: mmio page fault supportXiao Guangrong5-14/+248
The idea is from Avi: | We could cache the result of a miss in an spte by using a reserved bit, and | checking the page fault error code (or seeing if we get an ept violation or | ept misconfiguration), so if we get repeated mmio on a page, we don't need to | search the slot list/tree. | (https://lkml.org/lkml/2011/2/22/221) When the page fault is caused by mmio, we cache the info in the shadow page table, and also set the reserved bits in the shadow page table, so if the mmio is caused again, we can quickly identify it and emulate it directly Searching mmio gfn in memslots is heavy since we need to walk all memeslots, it can be reduced by this feature, and also avoid walking guest page table for soft mmu.

2011-07-24KVM: MMU: lockless walking shadow page tableXiao Guangrong2-8/+132

2011-07-24KVM: MMU: do not need atomicly to set/clear spteXiao Guangrong1-15/+71
Now, the spte is just from nonprsent to present or present to nonprsent, so we can use some trick to set/clear spte non-atomicly as linux kernel does Signed-off-by: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-07-24KVM: MMU: introduce the rules to modify shadow page tableXiao Guangrong1-34/+69
Introduce some interfaces to modify spte as linux kernel does: - mmu_spte_clear_track_bits, it set the spte from present to nonpresent, and track the stat bits(accessed/dirty) of spte - mmu_spte_clear_no_track, the same as mmu_spte_clear_track_bits except tracking the stat bits - mmu_spte_set, set spte from nonpresent to present - mmu_spte_update, only update the stat bits Now, it does not allowed to set spte from present to present, later, we can drop the atomicly opration for X86_32 host, and it is the preparing work to get spte on X86_32 host out of the mmu lock Signed-off-by: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-07-24KVM: MMU: abstract some functions to handle fault pfnXiao Guangrong2-18/+41

2011-07-24KVM: MMU: filter out the mmio pfn from the fault pfnXiao Guangrong1-2/+2
If the page fault is caused by mmio, the gfn can not be found in memslots, and 'bad_pfn' is returned on gfn_to_hva path, so we can use 'bad_pfn' to identify the mmio page fault. And, to clarify the meaning of mmio pfn, we return fault page instead of bad page when the gfn is not allowd to prefetch Signed-off-by: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-07-24KVM: MMU: remove bypass_guest_pfXiao Guangrong6-128/+33
The idea is from Avi: | Maybe it's time to kill off bypass_guest_pf=1. It's not as effective as | it used to be, since unsync pages always use shadow_trap_nonpresent_pte, | and since we convert between the two nonpresent_ptes during sync and unsync.

2011-07-24KVM: MMU: cleanup for FNAME(fetch)Xiao Guangrong1-2/+2

2011-07-23virtio: expose for non-virtualization users tooOhad Ben-Cohen7-37/+0
virtio has been so far used only in the context of virtualization, and the virtio Kconfig was sourced directly by the relevant arch Kconfigs when VIRTUALIZATION was selected. Now that we start using virtio for inter-processor communications, we need to source the virtio Kconfig outside of the virtualization scope too. Moreover, some architectures might use virtio for both virtualization and inter-processor communications, so directly sourcing virtio might yield unexpected results due to conflicting selections. The simple solution offered by this patch is to always source virtio's Kconfig in drivers/Kconfig, and remove it from the appropriate arch Kconfigs. Additionally, a virtio menu entry has been added so virtio drivers don't show up in the general drivers menu. This way anyone can use virtio, though it's arguably less accessible (and neat!) for virtualization users now. Note: some architectures (mips and sh) seem to have a VIRTUALIZATION menu merely for sourcing virtio's Kconfig, so that menu is removed too.

Do not trace arch_local_save_flags(), arch_local_irq_*() and friends. Although they are marked inline, gcc may still make a function out of them and add it to the pool of functions that are traced by the function tracer. This can cause undesirable results (kernel panic, triple faults, etc). Add the notrace notation to prevent them from ever being traced.

2011-07-23Blackfin: dpmc: optimize hibernate/resume pathMike Frysinger2-439/+572
The current save logic used in hibernation is to do a MMR load (base + offset) into a register, and then push that onto the stack. Then when restoring, pop off the stack into a register followed by a MMR store (base + offset). These use plenty of 32bit insns rather than 16bit, are pretty long winded, and full of pipeline bubbles. So, by taking advantage of MMRs that are contiguous, the multi-register push/pop insn, and register abuse, we can shrink this code considerably. When saving, the new logic does a lot of loads into the data and pointer registers before executing a single multi-register push insn. Then when restoring, we do a single multi-register pop insn followed by a lot of stores. Overall, this allows us to cut the insn count by ~30%, the code size by ~45%, and drastically reduce the register hazards that trigger bubbles in the pipeline.

2011-07-23Blackfin: dpmc: do not save/restore EVT0/EVT1/EVT4 when hibernatingMike Frysinger1-6/+0
EVT0 is for emulation, EVT1 is for reset, and EVT4 is the "global int disable" region. None of these are used by software (or even hardware), so don't bother saving/restoring them when we hibernate since nothing ever uses these in Linux (the only thing they would be useful for is core-memory scratch, but that's just crazy talk).
