This patchset based on the patchset "RISC-V: KVM: Add Zicfiss/Zicfilp support".
The patch includes all the function of original patchset from Quan: adding the Svadu/Zicfiss/Zicfilp FWFT for the RISC-V KVM. And this patchset already passes the KVM unit test. Follow the patchset (Which is queued for v7.2) https://lore.kernel.org/kvm/[email protected]/ Test with the patch applied https://lore.kernel.org/all/[email protected] Changed from v2: - https://lore.kernel.org/kvm/[email protected]/ 1. rebase with Yong-Xuan's patch set 2. Add SSP CSR context switch/set/get 3. Move the software-check exception set/unset into FWFT 4. Only delegate software-check exception when Zicfiss/Zicfilp is enabled. 5. Make KVM SBI_FWFT_PTE_AD_HW_UPDATING depends on both Svadu and Svade enabled. Changed from Quan's v1: - https://lore.kernel.org/kvm/[email protected]/ 1. rebase to the latest master. 2. Split Svadu change as separate patch 3. Fix all build error from the original series 4. Remove the Svadu check in kvm_riscv_vcpu_config_ran_once() and in favor of the FWFT. 5. Remove the LPE/SSE setting bit in kvm_riscv_vcpu_config_ran_once() (kvm_riscv_vcpu_setup_config() in original patchset) Inochi Amaoto (8): RISC-V: KVM: Add support for Svadu FWFT features KVM: riscv: selftests: add Svadu FWFT extension to get-reg-list test RISC-V: KVM: Allow Zicfiss/Zicfilp extensions for Guest/VM RISC-V: KVM: Add ssp context save/restore RISC-V: KVM: Handle software-check exits for VCPU RISC-V: KVM: Delegate SPELP bit to VS/VU mode if landing pad is enabled.
