Subject: [GIT PULL] KVM/riscv changes for 6.13 From: Anup Patel To: Paolo Bonzini Cc: Palmer Dabbelt , Palmer Dabbelt , Andrew Jones , Atish Patra , Atish Patra , "open list:KERNEL VIRTUAL MACHINE FOR RISC-V (KVM/riscv)" , KVM General , linux-riscv Date: Fri, 8 Nov 2024 17:07:34 +0530 Hi Paolo, We have the following KVM RISC-V changes for 6.13: 1) Accelerate KVM RISC-V when running as a guest 2) Perf support to collect KVM guest statistics from host side In addition, the pointer masking support (Ssnpm and Smnpm) for KVM guest is going through the RISC-V tree. I also have Svade and Svadu support for host and guest in my queue which I will send in the second week of the merge window to avoid conflict with the RISC-V tree. Please pull.
