From mboxrd@z Thu Jan 1 00:00:00 1970 From: Anup Patel Date: Mon, 4 Sep 2023 09:33:38 +0530 Subject: [PATCH 0/8] OpenSBI sparse HART id support Message-ID: <20230904040346.118604-1-apatel@ventanamicro.com> List-Id: To: opensbi@lists.infradead.org MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit 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 include/sbi/sbi_domain.h | 6 +-- include/sbi/sbi_hartmask.h | 75 ++++++++++++++++++++++++------- include/sbi/sbi_ipi.h | 14 +++--- include/sbi/sbi_platform.h | 28 ------------ include/sbi/sbi_scratch.h | 49 ++++++++++++++++---- lib/sbi/sbi_domain.c | 82 ++++++++++++++++------------------ lib/sbi/sbi_hsm.c | 30 ++++++------- lib/sbi/sbi_init.c | 28 +++++++----- lib/sbi/sbi_ipi.c | 28 ++++++------ lib/sbi/sbi_platform.c | 17 ------- lib/sbi/sbi_scratch.c | 37 +++++++++------ lib/sbi/sbi_system.c | 5 ++- lib/sbi/sbi_tlb.c | 14 +++--- lib/utils/fdt/fdt_domain.c | 4 +- lib/utils/ipi/aclint_mswi.c | 14 +++--- lib/utils/ipi/andes_plicsw.c | 8 +++- lib/utils/irqchip/imsic.c | 4 +- platform/generic/andes/ae350.c | 2 +- 18 files changed, 246 insertions(+), 199 deletions(-) -- 2.34.1
