This is the series of spec conformance bug fixes and code cleanups. We would like to get this series in after our core changes in v8.2.
- Implements WARL behavior for CSRs that don't support writes - Improves specification conformance of the page table walker - Change access checks from ternary operator to if statements - Checks for misaligned PPNs - Disallow M-mode or S-mode from fetching from User pages - Adds reserved PTE flag check: W or W|X - Improves page walker comments and general readability - Several trivial code cleanups to hw/riscv - Replacing hard coded constants with reference to enums or the machine memory maps. - Adds bounds checks when writing device-tree to ROM Michael Clark (22): RISC-V: Make virt create_fdt interface consistent RISC-V: Replace hardcoded constants with enum values RISC-V: Make virt board description match spike RISC-V: Use ROM base address and size from memory map RISC-V: Remove redundant identity_translate from load_elf RISC-V: Mark ROM read-only after copying in code and config RISC-V: Remove unused class definitions from machines RISC-V: Make sure the emulated rom has space for device-tree RISC-V: Include hexidecimal instruction in disassembly RISC-V: Hold rcu_read_lock when accessing memory directly RISC-V: Improve page table walker spec compliance RISC-V: Update E order and I extension order RISC-V: Make spike and virt header guards more specific RISC-V: Make virt header comment title consistent RISC-V: Use memory_region_is_ram in atomic pte update RISC-V: Remove EM_RISCV ELF_MACHINE indirection from load_elf RISC-V: Ingore satp writes and return 0 for reads when no-mmu RISC-V: Remove braces from satp case statement with no locals RISC-V: riscv-qemu port supports sv39 and sv48 RISC-V: vectored traps are optional RISC-V: No traps on writes to misa,minstret[h],mcycle[h] RISC-V: Remove support for adhoc X_COP local-interrupt disas/riscv.c | 39 +++++++++++---------- hw/riscv/sifive_clint.c | 9 ++--- hw/riscv/sifive_e.c | 34 ++---------------- hw/riscv/sifive_u.c | 65 +++++++++++----------------------- hw/riscv/spike.c | 65 +++++++++++++--------------------- hw/riscv/virt.c | 77 ++++++++++++++--------------------------- include/hw/riscv/sifive_clint.h | 4 +++ include/hw/riscv/sifive_e.h | 9 ----- include/hw/riscv/sifive_u.h | 13 +++---- include/hw/riscv/spike.h | 16 ++++----- include/hw/riscv/virt.h | 21 ++++------- target/riscv/cpu.c | 2 +- target/riscv/cpu.h | 6 ++-- target/riscv/cpu_bits.h | 3 -- target/riscv/helper.c | 63 +++++++++++++++++++++++---------- target/riscv/op_helper.c | 52 ++++++++++++++-------------- 16 files changed, 193 insertions(+), 285 deletions(-) -- 2.7.0
