lib: Emit lr and sc instructions based on -march flags

2025-03-28T13:22:05Z

When -march=rv64im_zalrsc_zicsr is used, provide atomic operations and locks using lr and sc instructions only. Signed-off-by: Chao-ying Fu Reviewed-by: Anup Patel Link: https://lore.kernel.org/r/20250226014727.19710-1-cfu@mips.com Signed-off-by: Anup Patel

firmware: Bring back FW_TEXT_START as an optional parameter

2024-05-23T05:20:23Z

Bring back FW_TEXT_START as an optional parameter to allow users explicitly specify compile time address for loading debug symbols. When not specified, the FW_TEXT_START is assumed to be 0. Fixes: d4d2582eef7a ("firmware: remove FW_TEXT_START") Signed-off-by: Anup Patel Tested-by: Clément Léger

firmware: remove FW_TEXT_START

2024-04-10T04:20:24Z

Now opensbi can run at any address via dynamic relocation. We can remove FW_TEXT_START. Signed-off-by: Xiang W Reviewed-by: Anup Patel Tested-by: Anup Patel

firmware: fix section types

2023-12-09T08:56:58Z

These sections are only intended to hold data, and should not be executable. Signed-off-by: Matt Waltz Reviewed-by: Xiang W Reviewed-by: Anup Patel

firmware: payload: test: Change to SBI v2.0 DBCN ecalls

2023-09-06T11:20:50Z

As the the "Console Putchar" extension is already legacy and may be removed in the furture. So replace it with the SBI v2.0 "DBCN" extension. Signed-off-by: Inochi Amaoto Reviewed-by: Anup Patel

firmware: payloads: Optimize usage of "ALIGN"

Delete the redundant "ALIGN" and adjust the position of "ALIGN" Signed-off-by: Leizheng Zhang Reviewed-by: Andrew Jones Reviewed-by: Atish Patra Reviewed-by: Bin Meng

payloads/test: Add support for SBI v0.2 ecalls

2021-08-20T04:18:45Z

It can be useful to make SBI v0.2 or newer ecalls from this payload for testing purposes. To support this, convert the macros to use the extension/function parameter convention. Signed-off-by: Samuel Holland Reviewed-by: Atish Patra

firmware: Use lla to access all global symbols

2021-03-19T09:27:45Z

When OpenSBI is compiled as fPIE mode, the assembler will translate "la" to GOT reference pattern. It will cause to cost an additional load instruction when obtaining the symbol address. However, if the symbol locates within the positive or negative 2GB region, we can use "lla" instead of "la" to avoid unneeded GOT references. This patch assumes that the OpenSBI image excluding the payload does not exceed 2GB. Based on this assumption, all "la" instructions are replaced by "lla" to avoid performance degradation when compiling as fPIE mode. Signed-off-by: Vincent Chen Reviewed-by: Anup Patel

firmware: Fix placement of .align directives

2020-01-10T04:00:27Z

Move the .align directives after switching the section. We want to align the start of the current section, not the end of the previous section. This also obsoletes the misguided workaround of disabling relaxation. Signed-off-by: Andreas Schwab Reviewed-by: Anup Patel

lib: Rename existing SBI implementation as 0.1.

2019-10-03T03:23:52Z

Current SBI implementation is now considered as version 0.1 and will be removed/replaced with newer extension/functions in future. Rename the existing implementations accordingly to be in sync with the specification. Signed-off-by: Atish Patra Reviewed-by: Anup Patel Reviewed-by: Zong Li
