2013-04-29ARM: KVM: iterate over all CPUs for CPU compatibility checkAndre Przywara1-3/+12
kvm_target_cpus() checks the compatibility of the used CPU with KVM, which is currently limited to ARM Cortex-A15 cores. However by calling it only once on any random CPU it assumes that all cores are the same, which is not necessarily the case (for example in Big.Little).

2013-04-29ARM: KVM: promote vfp_host pointer to generic host cpu contextMarc Zyngier1-14/+14
We use the vfp_host pointer to store the host VFP context, should the guest start using VFP itself. Actually, we can use this pointer in a more generic way to store CPU speficic data, and arm64 is using it to dump the whole host state before switching to the guest. Simply rename the vfp_host field to host_cpu_context, and the corresponding type to kvm_cpu_context_t. No change in functionnality.

2013-04-29ARM: KVM: add architecture specific hook for capabilitiesMarc Zyngier1-1/+1
Most of the capabilities are common to both arm and arm64, but we still need to handle the exceptions.

2013-04-29ARM: KVM: perform HYP initilization for hotplugged CPUsMarc Zyngier2-22/+62
Now that we have the necessary infrastructure to boot a hotplugged CPU at any point in time, wire a CPU notifier that will perform the HYP init for the incoming CPU. Note that this depends on the platform code and/or firmware to boot the incoming CPU with HYP mode enabled and return to the kernel by following the normal boot path (HYP stub installed).

2013-04-29ARM: KVM: switch to a dual-step HYP init codeMarc Zyngier3-64/+157
Our HYP init code suffers from two major design issues: - it cannot support CPU hotplug, as we tear down the idmap very early - it cannot perform a TLB invalidation when switching from init to runtime mappings, as pages are manipulated from PL1 exclusively The hotplug problem mandates that we keep two sets of page tables (boot and runtime). The TLB problem mandates that we're able to transition from one PGD to another while in HYP, invalidating the TLBs in the process. To be able to do this, we need to share a page between the two page tables. A page that will have the same VA in both configurations. All we need is a VA that has the following properties: - This VA can't be used to represent a kernel mapping. - This VA will not conflict with the physical address of the kernel text The vectors page seems to satisfy this requirement: - The kernel never maps anything else there - The kernel text being copied at the beginning of the physical memory, it is unlikely to use the last 64kB (I doubt we'll ever support KVM on a system with something like 4MB of RAM, but patches are very welcome). Let's call this VA the trampoline VA. Now, we map our init page at 3 locations: - idmap in the boot pgd - trampoline VA in the boot pgd - trampoline VA in the runtime pgd The init scenario is now the following: - We jump in HYP with four parameters: boot HYP pgd, runtime HYP pgd, runtime stack, runtime vectors - Enable the MMU with the boot pgd - Jump to a target into the trampoline page (remember, this is the same physical page!) - Now switch to the runtime pgd (same VA, and still the same physical page!) - Invalidate TLBs - Set stack and vectors - Profit! (or eret, if you only care about the code). Note that we keep the boot mapping permanently (it is not strictly an idmap anymore) to allow for CPU hotplug in later patches.

2013-04-29ARM: KVM: rework HYP page table freeingMarc Zyngier2-102/+81
There is no point in freeing HYP page tables differently from Stage-2. They now have the same requirements, and should be dealt with the same way. Promote unmap_stage2_range to be The One True Way, and get rid of a number of nasty bugs in the process (good thing we never actually called free_hyp_pmds before...).

2013-04-29ARM: KVM: move to a KVM provided HYP idmapMarc Zyngier1-1/+23
After the HYP page table rework, it is pretty easy to let the KVM code provide its own idmap, rather than expecting the kernel to provide it. It takes actually less code to do so.

2013-04-29ARM: KVM: fix HYP mapping limitations around zeroMarc Zyngier1-11/+10
The current code for creating HYP mapping doesn't like to wrap around zero, which prevents from mapping anything into the last page of the virtual address space. It doesn't take much effort to remove this limitation, making the code more consistent with the rest of the kernel in the process.

2013-04-29ARM: KVM: simplify HYP mapping populationMarc Zyngier1-60/+42
The way we populate HYP mappings is a bit convoluted, to say the least. Passing a pointer around to keep track of the current PFN is quite odd, and we end-up having two different PTE accessors for no good reason. Simplify the whole thing by unifying the two PTE accessors, passing a pgprot_t around, and moving the various validity checks to the upper layers.

2013-03-07ARM: KVM: change kvm_tlb_flush_vmid to kvm_tlb_flush_vmid_ipaMarc Zyngier2-7/+10
v8 is capable of invalidating Stage-2 by IPA, but v7 is not.

2013-03-07ARM: KVM: fix address validation for HYP mappingsMarc Zyngier1-2/+7
__create_hyp_mappings() performs some kind of address validation before creating the mapping, by verifying that the start address is above PAGE_OFFSET. This check is not completely correct for kernel memory (the upper boundary has to be checked as well so we do not end up with highmem pages), and wrong for IO mappings (the mapping must exist in the vmalloc region). Fix this by using the proper predicates (virt_addr_valid and is_vmalloc_addr), which also work correctly on ARM64 (where the vmalloc region is below PAGE_OFFSET). Also change the BUG_ON() into a less agressive error return. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2013-03-07ARM: KVM: allow HYP mappings to be at an offset from kernel mappingsMarc Zyngier1-16/+27
arm64 cannot represent the kernel VAs in HYP mode, because of the lack of TTBR1 at EL2. A way to cope with this situation is to have HYP VAs to be an offset from the kernel VAs. Introduce macros to convert a kernel VA to a HYP VA, make the HYP mapping functions use these conversion macros. Also change the documentation to reflect the existence of the offset. On ARM, where we can have an identity mapping between kernel and HYP, the macros are without any effect. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
