lib: utils/timer: mtimer: only use regname for aclint

2023-12-27T06:27:33Z

The parser will fail if the timer is clint timer and has regname property. As the regname is only meaningful for aclint, it is more robust to only check regname for aclint timer.

lib: sbi: Remove the SBI_ETRAP error code

2023-12-19T10:26:37Z

The SBI_ETRAP error code was introduced only for doing trap redirection in generic sbi_ecall_handler(). Now the trap redirection is moved into sbi_ecall_legacy.c and SBI_ETRAP error code is only used in this source file so let us remove it. Signed-off-by: Anup Patel

lib: sbi: Allow ecall handlers to directly update register state

2023-12-19T10:26:37Z

Some of the upcoming SBI extensions (such as SSE) will directly update register state so improve the prototype of ecall handler to accommodate this. Further, this flexibility allows us to push the trap redirection from sbi_ecall_handler() to the sbi_ecall_legacy_handler(). Signed-off-by: Anup Patel

lib: utils/irqchip: Add shared MMIO region for PLIC in root domain

2023-12-19T10:26:37Z

On platforms with Smepmp, the MMIO regions accessed by M-mode need to be explicitly marked with M-mode only read/write or shared (both (M-mode and S-mode) read/write permission. If the above is not done then runtime PLIC access from M-mode on platforms with Smepmp will result in access fault when further results in CPU hotplug not working. Signed-off-by: Anup Patel

lib: sbi_tlb: Reduce size of struct sbi_tlb_info

2023-12-19T10:26:37Z

Let us reduce the size of struct sbi_tlb_info by doing the following: 1) Change the data type of asid and vmid fields to uint16_t 2) Replace local_fn() function pointer with an enum Based on the above, the size of struct sbi_tlb_info is reduced by 16 bytes on RV64 and 4 bytes on RV32.

lib: utils/fdt: Allow to use reg-names when parsing ACLINT

2023-12-11T05:05:32Z

Currently, the fdt_parse_aclint_node() follows a fixed order to parse ACLINT timer. This may cause the undesirable result when the ACLINT device does not support mtime without adding an empty entry for it in the DT. To be robust, make fdt_parse_aclint_node() support "reg-names" property, so it can parse the DT in an order independent way. For compatibility, fdt_parse_aclint_node() only use "reg-names" when parsing ACLINT timer, and will fallback to the old way if "reg-names" property is not found.
