2021-04-07KVM: arm64: Initialize VCPU mdcr_el2 before loading itAlexandru Elisei
When a VCPU is created, the kvm_vcpu struct is initialized to zero in kvm_vm_ioctl_create_vcpu(). On VHE systems, the first time vcpu.arch.mdcr_el2 is loaded on hardware is in vcpu_load(), before it is set to a sensible value in kvm_arm_setup_debug() later in the run loop. The result is that KVM executes for a short time with MDCR_EL2 set to zero. This has several unintended consequences: * Setting MDCR_EL2.HPMN to 0 is constrained unpredictable according to ARM DDI 0487G.a, page D13-3820. The behavior specified by the architecture in this case is for the PE to behave as if MDCR_EL2.HPMN is set to a value less than or equal to PMCR_EL0.N, which means that an unknown number of counters are now disabled by MDCR_EL2.HPME, which is zero. * The host configuration for the other debug features controlled by MDCR_EL2 is temporarily lost. This has been harmless so far, as Linux doesn't use the other fields, but that might change in the future. Let's avoid both issues by initializing the VCPU's mdcr_el2 field in kvm_vcpu_vcpu_first_run_init(), thus making sure that the MDCR_EL2 register has a consistent value after each vcpu_load().

SC7180 is further polished, the DisplayPort portion of the QMP phy is defined and several new SKUs of the Trogdor devices are introduced. The new SC7280 platform is introduced, with RPMH, RPMHPD, RPMCC, SPMI, CPU idle, SMMU and watchdog defined. SDM845 gains the camera related nodes and some cleanups.

Commit 941432d00768 ("arm64: dts: allwinner: Drop non-removable from SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module, along the way with the Pine64-LTS, which share the same base .dtsi. However while both boards indeed have a working CD GPIO on PF6, the polarity is different: the SOPine modules uses a "push-pull" socket, which has an active-high switch, while the Pine64-LTS use the more traditional push-push socket and the common active-low switch. Fix the polarity in the sopine.dtsi, and overwrite it in the LTS board .dts, to make the SD card work again on systems using SOPine modules.

2021-04-06arm64: KVM: Enable access to TRBE support for hostSuzuki K Poulose
For a nvhe host, the EL2 must allow the EL1&0 translation regime for TraceBuffer (MDCR_EL2.E2TB == 0b11). This must be saved/restored over a trip to the guest. Also, before entering the guest, we must flush any trace data if the TRBE was enabled. And we must prohibit the generation of trace while we are in EL1 by clearing the TRFCR_EL1. For vhe, the EL2 must prevent the EL1 access to the Trace Buffer.

At the moment, we check the availability of SPE on the given CPU (i.e, SPE is implemented and is allowed at the host) during every guest entry. This can be optimized a bit by moving the check to vcpu_load time and recording the availability of the feature on the current CPU via a new flag. This will also be useful for adding the TRBE support.

2021-04-06x86/sgx: Move provisioning device creation out of SGX driverSean Christopherson
And extract sgx_set_attribute() out of sgx_ioc_enclave_provision() and export it as symbol for KVM to use. The provisioning key is sensitive. The SGX driver only allows to create an enclave which can access the provisioning key when the enclave creator has permission to open /dev/sgx_provision. It should apply to a VM as well, as the provisioning key is platform-specific, thus an unrestricted VM can also potentially compromise the provisioning key. Move the provisioning device creation out of sgx_drv_init() to sgx_init() as a preparation for adding SGX virtualization support, so that even if the SGX driver is not enabled due to flexible launch control not being available, SGX virtualization can still be enabled, and use it to restrict a VM's capability of being able to access the provisioning key.

2021-04-06x86/sgx: Add helpers to expose ECREATE and EINIT to KVMSean Christopherson
The host kernel must intercept ECREATE to impose policies on guests, and intercept EINIT to be able to write guest's virtual SGX_LEPUBKEYHASH MSR values to hardware before running guest's EINIT so it can run correctly according to hardware behavior. Provide wrappers around __ecreate() and __einit() to hide the ugliness of overloading the ENCLS return value to encode multiple error formats in a single int. KVM will trap-and-execute ECREATE and EINIT as part of SGX virtualization, and reflect ENCLS execution result to guest by setting up guest's GPRs, or on an exception, injecting the correct fault based on return value of __ecreate() and __einit(). Use host userspace addresses (provided by KVM based on guest physical address of ENCLS parameters) to execute ENCLS/EINIT when possible. Accesses to both EPC and memory originating from ENCLS are subject to segmentation and paging mechanisms. It's also possible to generate kernel mappings for ENCLS parameters by resolving PFN but using __uaccess_xx() is simpler.

2021-04-06KVM: arm64: vgic-v3: Expose GICR_TYPER.Last for userspaceEric Auger
Commit 23bde34771f1 ("KVM: arm64: vgic-v3: Drop the reporting of GICR_TYPER.Last for userspace") temporarily fixed a bug identified when attempting to access the GICR_TYPER register before the redistributor region setting, but dropped the support of the LAST bit. Emulating the GICR_TYPER.Last bit still makes sense for architecture compliance though. This patch restores its support (if the redistributor region was set) while keeping the code safe. We introduce a new helper, vgic_mmio_vcpu_rdist_is_last() which computes whether a redistributor is the highest one of a series of redistributor contributor pages. With this new implementation we do not need to have a uaccess read accessor anymore.
