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: 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: sbi: Detect extensions from the ISA string in DT

2023-12-19T10:09:17Z

Enable access to some extensions through menvcfg and show them in "Boot HART ISA Extensions" if they are present in the device tree. Signed-off-by: Yong-Xuan Wang Reviewed-by: Anup Patel

lib: sbi: Using one array to define the name of extensions

2023-12-19T08:44:22Z

Define an array sbi_hart_ext to map extension ID and name , and use it for ISA parsing and printing out the supported extensions. Signed-off-by: Yong-Xuan Wang Reviewed-by: Anup Patel

lib: sbi: Refactor the code for enable extensions in menvfg CSR

2023-12-19T08:24:33Z

Use 1 variable to store the value of menvcfg. Signed-off-by: Yong-Xuan Wang Reviewed-by: Anup Patel

platform: recalculate heap size to support new tlb entry number

2023-12-11T03:53:24Z

Previous patch introduced a change that using hart count as the default number of tlb entries in the fifo. This makes the default tlb fifo size grow in square with the number of harts. So the default heap size is not enough to allocate tlb fifo when the hart count is big.

lib: sbi_pmu: Fix the counter info function

2023-12-08T17:20:23Z

The counter info should only return valid hardware counters for the ones set in the counter mask. Otherwise, it will report incorrect number of hardware counters to the supervisor if the platform has discontiguous counters.

lib: sbi_pmu: Add PMU snapshot definitions

2023-12-08T17:20:21Z

OpenSBI doesn't support SBI PMU snapshot yet as there is not much benefit unless the multiple counters overflow at the same time. Just add the definition and return not supported error at this moment. The default returned error is also not supported. Thus, no functional change intended.
