The address is shifted before obtaining the correct PMLEN value.\n2. riscv_pm_get_pmm() does not handle effective privilege mode correctly.\n3. mstatus.MPRV does not affect virtual-machine load/store instructions.\n4. Sign extension for virtual-machine load/store instructions (HLV.* and\n HSV.*) must be performed when vsatp.MODE != Bare.\n\nThis patchset fixes the above issues and also renames\nriscv_pm_get_virt_pmm() to riscv_pm_get_vm_ldst_pmm(), as the helper\nis only used when checking the PMM configuration for virtual-machine\nload/store instructions, rather than for VS/VU modes.\n\nChangelog:\n\nv4:\n * Rebase to the latest to-apply.next branch.\n\nv3:\n * Move riscv_cpu_eff_priv() to the header file and declare it as a\n static inline function.\n * Fix the MXR check bugs pointed out by Radim Krčmář.\n\nv2:\n * Check effective privilege mode in riscv_pm_get_pmm().\n * Fix pointer masking for virtual-machine load/store instructions\n (HLV.* and HSV.*).\n * Rename riscv_pm_get_virt_pmm() to riscv_pm_get_vm_ldst_pmm().\n\nFrank Chang (5):\n target/riscv: Add a helper to return the current effective priv mode\n target/riscv: Fix pointer masking PMM field selection logic\n target/riscv: Fix pointer masking for virtual-machine load/store insns\n target/riscv: Rename riscv_pm_get_virt_pmm() to\n riscv_pm_get_vm_ldst_pmm()\n target/riscv: Fix pointer masking translation mode check bug\n\nYong-Xuan Wang (1):\n target/riscv: fix address masking\n\n target/riscv/cpu.h | 41 +++++++++++++-\n target/riscv/cpu_helper.c | 110 +++++++++++++++++++++++++++----------\n target/riscv/internals.h | 8 +--\n target/riscv/tcg/tcg-cpu.c | 4 +-\n 4 files changed, 124 insertions(+), 39 deletions(-)\n\n--\n2.43.0"}
