lib: Handle page/access fault caused by unpriv load/store

2019-05-24T02:52:47Z

The unpriv load/store instruction from M-mode can cause page/access fault to M-mode if S-mode page table did not have mappings OR it did not have PMP access permission. To tackle this, we redirect trap back to S-mode if unpriv load/store instruction traps in M-mode. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

include: Make mstatus parameter optional for get_insn()

2019-04-01T04:40:38Z

The mstatus parameter of get_insn() is used to return MSTATUS CSR value which get_insn() saw. Most of the get_insn() callers don't use the value returned in mstatus so this patch makes mstatus parameter optional for get_insn(). Signed-off-by: Anup Patel

include: Rename sbi_unpriv.h to riscv_unpriv.h

2019-04-01T04:40:38Z

The sbi_unpriv.h has quite a few load_xyz() and store_xyz() helper routines based on RISC-V inline assembly for unpriviledged accesses from M-mode. These helper routines are similar to helper routines present in riscv_locks.h, riscv_io.h, and riscv_atomic.h so let's rename sbi_unpriv.h to riscv_unpriv.h. Signed-off-by: Anup Patel

lib: Remove unused mepc arg from load_xyz() and store_xyz() functions

This patch removes unused mepc arg from load_xyz() and store_xyz() unpriviledge access functions. Signed-off-by: Anup Patel

lib: Use CSR_ instead of for csr_*()

2019-02-14T04:01:18Z

Some older toolchains may not have all the csr's defined. Update all the csr functions to use the CSR_ #define values instead of the toolchain defined values. Suggested-by: Olof Johansson Signed-off-by: Atish Patra

riscv_asm.h: Use CSR_ instead of for csr_read()

2019-02-05T13:23:09Z

Some toolchains might not have all the CSRs available (as seen with GCC 7.2). So, instead use the defined CSR_ values. Signed-off-by: Olof Johansson
