platform: Use one unified per-HART stack size macro for all platforms

2020-03-14T03:44:00Z

As of today all platforms use 8KB of per-HART stack hence there is no need for each platform to define its own macro or use the magic number. Create one macro for all platforms. Platform still can use its own version if needed. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

include: Make sbi_current_hartid() as macro in riscv_asm.h

2020-03-13T06:52:02Z

The sbi_current_hartid() being a regular function is quite expensive because for callers it is a function call instead of a direct CSR read. This patch converts sbi_current_hartid() into a macro in riscv_asm.h. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

include: Remove disabled_hart_mask from sbi_platform

2020-03-11T10:00:12Z

The disabled_hard_mask in sbi_platform is only 64bits wide so we cannot disable a HART with HARTID > 63. To tackle this, we remove disabled_hart_mask and replace it with hart_disabled() platform callback. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Atish Patra

platform: kendryte/k210: Set per-HART stack size to 8KB

2020-03-08T05:43:31Z

All platform except kendryte/k210 use 8KB of per-HART stack hence this patch set per-HART stack size of kendryte/k210 to 8KB for consistency. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils: Support CLINT with 32bit MMIO access on RV64 system

2020-01-02T03:44:36Z

It is possible to have a CLINT implementation which supports only 32bit MMIO accesses on RV64 system so this patch extends our CLINT driver such that platform code can specify whether CLINT supports 64bit MMIO access. Signed-off-by: Anup Patel Reviewed-by: Atish Patra Reviewed-by: Zong Li

kendryte/k210: remove unused file

Commit 9dfe72057957 ("kendryte/k210: remove sysctl code") missed removing the file sysctl.c. Fix this here. Fixes: 9dfe72057957 ("kendryte/k210: remove sysctl code") Signed-off-by: Damien Le Moal Reviewed-by: Atish Patra

kendryte/k210: remove sysctl code

2019-09-05T13:20:37Z

Directly implement frequency discovery, making the sysctl code unnecessary. While at it, Move all macro definitions from platform.c into platform.h and cleanup that file, removing the need for the Apache 2.0 license and Canaan Inc copyright.

kendryte/k210: Use sifive UART driver

2019-09-05T13:17:56Z

The Kendryte K210 UARTHS is compatible with SiFive UART. So use the sifive uart driver and remove the k210 uarths platform code. Signed-off-by: Damien Le Moal Reviewed-by: Bin Meng Reviewed-by: Anup Patel

platform: Remove the ipi_sync method from all platforms.

2019-08-16T03:12:58Z

OpenSBI manages outstanding TLB flush requests by queueing them in a fifo synchronously. An ipi sync which uses an atomic operation on MMIO address is no longer required. Remove the ipi sync method from platform header and all usage. Signed-off-by: Atish Patra Reviewed-by: Anup Patel
