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

lib: Redirect unhandled traps from non-M modes to S mode

2019-04-22T04:26:20Z

In case we didn't handle a trap with one of the available handlers, check if the trap comes from S or U mode and redirect it to S mode's trap handler. Signed-off-by: Nick Kossifidis

include: Add PRILX define to help print unsigned long

2019-02-20T06:32:40Z

The unsigned long is always machine word size. This means it is 4 bytes on 32bit system and 8 bytes on 64bit system. This patch adds PRILX define for sbi_printf() which will help us print unsigned long without worrying whether it is 32bit or 64bit system. 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

lib: Remove target_hart and hartid parameter from TIMER callbacks

2019-01-23T03:09:26Z

The target_hart and hartid paramter of TIMER callbacks is not required because it always current hartid which can be obtained using sbi_current_hartid() API. Signed-off-by: Anup Patel

lib: Remove source_hart and hartid parameter from IPI callbacks

2019-01-23T03:09:26Z

The source_hart and hartid parameter is really not required in IPI callbacks of sbi_platform because current hartid can always be obtained by calling sbi_current_hartid() API. Signed-off-by: Anup Patel
