lib: Allow overriding SBI implementation ID

2020-04-19T11:30:05Z

Ideally, the SBI implementation ID for OpenSBI should always be 0x1 (as mentioned in SBI v0.2 spec) but external firmware (such as EDK2) which use OpenSBI as library might want to override the SBI implementation ID with their custom implementation ID.

lib: Support vector extension

2020-04-17T04:00:17Z

Enable vector context in mstatus by updating the corresponding bits in mstatus if vector extension is supported by the hart. Signed-off-by: Atish Patra Reviewed-by: Bin Meng Reviewed-by: Anup Patel

include: sbi_console: Remove scratch parameter from sbi_dprintf()

2020-03-28T08:02:58Z

This patch removes scratch parameter from sbi_dprintf() function because sbi_dprintf() can use sbi_scratch_thishart_ptr() to get current HART scratch space. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

include: sbi_timer: Remove scratch parameter from most funcitons

2020-03-28T08:02:55Z

This patch removes scratch parameter from most sbi_timer functions. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

include: sbi_system: Remove scratch parameter and redundant functions

2020-03-28T08:02:52Z

include: sbi_tlb: Remove scratch parameter from sbi_tlb_request()

2020-03-28T08:02:44Z

The sbi_ipi_send_many() should get current HART scratch pointer on it's own using eventually hence removing scratch parameter from sbi_tlb_request(). Signed-off-by: Anup Patel

lib: sbi_scratch: Introduce sbi_scratch_last_hartid() API

2020-03-28T08:02:41Z

The patch adds sbi_scratch_last_hartid() API which returns last HART id having a scratch space. We can use this new API to optimize places where we iterate over HART id from 0 to SBI_HARTMASK_MAX_BITS. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

include: Use more consistent name for atomic xchg() and cmpxchg()

2020-03-28T08:02:38Z

We should remove the "arch_" prefix from atomic xchg() and cmpxchg() function names to have consistent naming of all atomic functions. Signed-off-by: Anup Patel Reviewed-by: Atish Patra
