The issue reported here:
https://lkml.org/lkml/2020/7/28/1085
is still present as of 5.9-rc3; it was introduced in the 5.8 cycle.
When the problem occurs, iscsid crashes and iscsi volumes fail to come
up, which makes the machine quite sad if the volumes are critical to
its function.

Since kprobe_event= cmdline option allows user to put kprobes on the

This series adds initial KVM RISC-V support. Currently, we are able to boot
Linux on RV64/RV32 Guest with multiple VCPUs.
Key aspects of KVM RISC-V added by this series are:
1. No RISC-V specific KVM IOCTL
2. Minimal possible KVM world-switch which touches only GPRs and few CSRs
3. Both RV64 and R
For KVM RISC-V, we use KVM_GET_ONE_REG/KVM_SET_ONE_REG ioctls to access
VCPU config and registers from user-space.
We have three types of VCPU registers:
1. CONFIG - these are VCPU config and capabilities
2. CORE - these are VCPU general purpose registers
3. CSR- these are VCPU control and s

We implement a simple VMID allocator for Guests/VMs which:
1. Detects number of VMID bits at boot-time
2. Uses atomic number to track VMID version and increments
VMID version whenever we run-out of VMIDs
3. Flushes Guest TLBs on all host CPUs whenever we run-out
of VMIDs
4. Force updates HW S
We get illegal instruction trap whenever Guest/VM executes WFI
instruction.
This patch handles WFI trap by blocking the trapped VCPU using
kvm_vcpu_block() API. The blocked VCPU will be automatically
resumed whenever a VCPU interrupt is injected from user-space
or from in-kernel IRQCHIP emulation.
Hi Prabhakar,

- The exit
From: Atish Patra
This patch adds floating point (F and D extension) context save/restore
for guest VCPUs. The FP context is saved and restored lazily only when
kernel enter/exits the in-kernel run loop and not during the KVM world
switch. This way FP save/restore has minimal impact on KVM perfor

This patch implements MMU notifiers for KVM RISC-V so that Guest
physical address space is in-sync with Host physical address space.
This will allow swapping, page migration, etc to work transparently
with KVM RISC-V.

This patch implements all required functions for programming
the stage2 page table for each Guest/VM.
At high-level, the flow of stage2 related functions is similar
from KVM ARM/ARM64 implementation but the stage2 page table
format is quite different for KVM RISC-V.

This patch implements the VCPU world-switch for KVM RISC-V.
The KVM RISC-V world-switch (i.e. __kvm_riscv_switch_to()) mostly
switches general purpose registers, SSTATUS, STVEC, SSCRATCH and
HSTATUS CSRs. Other CSRs are switched via vcpu_load() and vcpu_put()
interface in kvm_arch_vcpu_load() and
This patch implements VCPU interrupts and requests which are both
asynchronous events.
The VCPU interrupts can be set/unset using KVM_INTERRUPT ioctl from
user-space. In future, the in-kernel IRQCHIP emulation will use
kvm_riscv_vcpu_set_interrupt() and kvm_riscv_vcpu_unset_interrupt()
functions t
We will get stage2 page faults whenever Guest/VM access SW emulated

This patch adds initial skeletal KVM RISC-V support which has:
1. A simple implementation of arch specific VM functions
except kvm_vm_ioctl_get_dirty_log() which will implemeted
in-future as part of stage2 page loging.
2. Stubs of required arch specific VCPU functions except
kvm_arch_vcpu_
This patch implements VCPU create, init and destroy functions
required by generic KVM module. We don't have much dynamic
resources in struct kvm_vcpu_arch so these functions are quite
simple for KVM RISC-V.

This series adds initial KVM RISC-V support. Currently, we are able to boot
Linux on RV64/RV32 Guest with multiple VCPUs.
Key aspects of KVM RISC-V added by this series are:
1. No RISC-V specific KVM IOCTL
2. Minimal possible KVM world-switch which touches only GPRs and few CSRs
3. Both RV64 and R
