* KVM: PPC: Book3S HV: Add fast real-mode H_RANDOM implementation.Michael Ellerman2015-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | Some PowerNV systems include a hardware random-number generator. This HWRNG is present on POWER7+ and POWER8 chips and is capable of generating one 64-bit random number every microsecond. The random numbers are produced by sampling a set of 64 unstable high-frequency oscillators and are almost completely entropic. PAPR defines an H_RANDOM hypercall which guests can use to obtain one 64-bit random sample from the HWRNG. This adds a real-mode implementation of the H_RANDOM hypercall. This hypercall was implemented in real mode because the latency of reading the HWRNG is generally small compared to the latency of a guest exit and entry for all the threads in the same virtual core. Userspace can detect the presence of the HWRNG and the H_RANDOM implementation by querying the KVM_CAP_PPC_HWRNG capability. The H_RANDOM hypercall implementation will only be invoked when the guest does an H_RANDOM hypercall if userspace first enables the in-kernel H_RANDOM implementation using the KVM_CAP_PPC_ENABLE_HCALL capability.

* kvmppc: Implement H_LOGICAL_CI_{LOAD,STORE} in KVMDavid Gibson2015-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On POWER, storage caching is usually configured via the MMU - attributes such as cache-inhibited are stored in the TLB and the hashed page table. This makes correctly performing cache inhibited IO accesses awkward when the MMU is turned off (real mode). Some CPU models provide special registers to control the cache attributes of real mode load and stores but this is not at all consistent. This is a problem in particular for SLOF, the firmware used on KVM guests, which runs entirely in real mode, but which needs to do IO to load the kernel. To simplify this qemu implements two special hypercalls, H_LOGICAL_CI_LOAD and H_LOGICAL_CI_STORE which simulate a cache-inhibited load or store to a logical address (aka guest physical address). SLOF uses these for IO. However, because these are implemented within qemu, not the host kernel, these bypass any IO devices emulated within KVM itself. The simplest way to see this problem is to attempt to boot a KVM guest from a virtio-blk device with iothread / dataplane enabled. The iothread code relies on an in kernel implementation of the virtio queue notification, which is not triggered by the IO hcalls, and so the guest will stall in SLOF unable to load the guest OS. This patch addresses this by providing in-kernel implementations of the 2 hypercalls, which correctly scan the KVM IO bus. Any access to an address not handled by the KVM IO bus will cause a VM exit, hitting the qemu implementation as before. Note that a userspace change is also required, in order to enable these new hcall implementations with KVM_CAP_PPC_ENABLE_HCALL.

* powerpc: Export __spin_yieldSuresh E. Warrier2015-04-21
| | | | | | | | | | | | | | Export __spin_yield so that the arch_spin_unlock() function can be invoked from a module. This will be required for modules where we want to take a lock that is also is acquired in hypervisor real mode. Because we want to avoid running any lockdep code (which may not be safe in real mode), this lock needs to be an arch_spinlock_t instead of a normal spinlock.

This commit improves the readability of the CRC verification by placing the individual 4 bytes of each byte array into an 32-bit unsigned integer and comparing the two resulting integers. Thanks to Larry Finger for spotting the code style issues in the previous version of this commit, and thanks to Joe Perches for suggesting the use of 32-bit integer comparisons instead of byte array comparisons.
