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

lib: Add doxygen style documentation for sbi_platform

2019-01-22T06:10:15Z

This patch adds doxygen style documenation for struct sbi_platform and related functions/macros/defines. Signed-off-by: Anup Patel

include: Add documentation for sbi_trap_regs and friends

lib: Redirect illegal instruction trap to S-mode when not handled

2018-12-31T03:58:26Z

Currently, we fail with error SBI_ENOTSUPP when we are not able to handle illegal instruction trap. Instead, we should just redirect illegal instruction trap to S-mode when not handled. This redirection of illegal instruction trap will help lazy save/restore of floating point registers to work correctly in Linux kernel. Signed-off-by: Anup Patel

lib: Print mtval in sbi_trap_error()

2018-12-27T04:36:38Z

The mtval CSR is very useful information when debugging hence print it upon trap error in sbi_trap_error(). Signed-off-by: Anup Patel
