Implement SBI CPPC extension. This extension is only available when OpenSBI platform provides a CPPC device to generic library. Signed-off-by: Sunil V L Reviewed-by: Andrew Jones Reviewed-by: Anup Patel

lib: sbi: Add system suspend skeleton

2023-02-27T14:13:52Z

We implement SBI debug console extension as one of the replacement SBI extensions. This extension is only available when OpenSBI platform provides a console device to generic library. Signed-off-by: Anup Patel Reviewed-by: Atish Patra Reviewed-by: Xiang W Reviewed-by: Bin Meng

lib: sbi_ecall: Split up sbi_ecall_replace

2022-11-15T11:14:03Z

Split up sbi_ecall_replace so that each extension is in its individual file. Also reorganize the corresponding section in lib/sbi/objects.mk so that it is grouped by extension, now that the object file targets are split up. Signed-off-by: Vivian Wang Reviewed-by: Anup Patel

lib: sbi_ecall: Add Kconfig option for each extension

2022-10-23T05:31:33Z

For each SBI extension, we: - Add a Kconfig option for it - Add the extension to sbi_ecall_exts only if the extension is enabled - Add the corresponding sbi_ecall_* object file only if the extension is enabled Special cases are as follows: - The legacy extensions are lumped together as one 'big' extension, as has always been the case in OpenSBI code. - The platform-defined vendor extensions are regarded as one extension. - The Base extension cannot be disabled. - sbi_ecall_replace implements multiple extensions, so it's not easy to avoid linking it in. Enable it always, and use #ifdef to disable/enable individual extensions. Signed-off-by: Vivian Wang Reviewed-by: Andrew Jones Reviewed-by: Anup Patel

lib: sbi_ecall: Generate extensions list with carray

2022-10-23T05:30:30Z

Instead of hard-coding the list of extensions in C code, use carray to generate the list of extensions. Using carray makes adding and removing extensions slightly cleaner. This also paves the way for using Kconfig to disable unneeded extensions. Signed-off-by: Vivian Wang Reviewed-by: Andrew Jones Reviewed-by: Anup Patel

lib: sbi: Add a simple external interrupt handling framework

2022-02-28T04:13:12Z

Currently, the external interrupt handling is scattered between sbi_init and sbi_trap. This patch moves all external interrupt handling into a simple framework called sbi_irqchip. Signed-off-by: Anup Patel Reviewed-by: Xiang W Reviewed-by: Atish Patra

lib: sbi: Implement SBI PMU extension

2021-07-11T05:08:02Z

RISC-V SBI specfication 0.3 defines a PMU extension that allows supervisor mode to start/stop/configure pmu related events. This patch implements all of the functionality defined in the specification. Reviewed-by: Anup Patel Signed-off-by: Atish Patra

lib: sbi: Add PMU support

2021-07-11T04:53:18Z

RISC-V SBI v0.3 specification defined a PMU extension to configure/start/stop the hardware/firmware pmu events. Implement PMU support in OpenSBI library. The implementation is agnostic of event to counter mapping & mhpmevent value configuration. That means, it expects platform hooks will be used to set up the mapping and provide the mhpmevent value at runtime. Reviewed-by: Anup Patel Signed-off-by: Atish Patra
