Subject: [PATCH 0/8] OpenSBI sparse HART id support
Date: Mon, 4 Sep 2023 09:33:38 +0530 [thread overview]
Message-ID: <20230904040346.118604-1-apatel@ventanamicro.com> (raw)
Currently, we requires HART id to be less than SBI_HARTMASK_MAX_BITS
because we use HART id as bit index in the sbi_hartmask. This is a
very limiting requirement because RISC-V platforms can have sparse
HART ids (with possibly large values).
This series addresses the above described limitation by adding
sparse HART id support in OpenSBI.
These patches can also be found the full_sparse_hartid_v1 branch at
https://github.com/avpatel/opensbi.git
Anup Patel (7):
lib: sbi: Introduce HART index in sbi_scratch
lib: sbi: Remove sbi_platform_hart_index/invalid() functions
lib: sbi: Use sbi_scratch_last_hartindex() in remote TLB managment
lib: sbi: Prefer hartindex over hartid in IPI framework
lib: sbi: Remove sbi_scratch_last_hartid() macro
lib: sbi: Maximize the use of HART index in sbi_domain
include: sbi: Remove sbi_hartmask_for_each_hart() macro
Xiang W (1):
lib: sbi: Extend sbi_hartmask to support both hartid and hartindex
