2024-06-19T12:45:28Z

The SBI FWFT extension defines a set of function that can be called to control the configuration of some platform features (misaligned trap delegation, etc). This patch implements sbi_fwft_set() and sbi_fwft_get() as defined in the specification [1].

lib: sbi: Add support for Supervisor Software Events extension

2024-04-05T10:17:30Z

This extension [1] allows to deliver events from SBI to supervisor via a software mechanism. This extension defines events (either local or global) which are signaled by the SBI on specific signal sources (IRQ, exceptions, etc) and are injected to be executed in supervisor mode.

lib: tests: Move tests to a separate directory

2024-03-19T05:50:40Z

Move all of the SBIUnit-related code into the lib/sbi/tests directory. Update 'Makefile' to index objects from the tests subdirectory. I don't think creating the full separate list of Makefile variables (libsbitests-objs-path-y, libsbitests-object-mks, etc. as it is done for libsbiutils) is necessary for the tests because: 1) `lib/sbi/tests/objects.mk` is already indexed into 'libsbi-objects-mks' since the find expression for the libsbi-object-mks variable looks for objects.mk files in the nested directories as well). 2) Tests are tightly coupled with the `lib/sbi/` sources, therefore it may be reasonable to store the list of lib/sbi and lib/sbi/tests object files together in the libsbi-objs-path-y variable. Additionally, update relative paths in the tests where necessary. Signed-off-by: Ivan Orlov Reviewed-by: Anup Patel

lib: sbi: Add initial domain context management support

2024-03-10T04:56:42Z

The domain context management component in OpenSBI provides basic CPU context management routines for existing OpenSBI domain. As domain extension, it was initially designed to facilitate the suspension and resumption of domains, enabling secure domains to efficiently share CPU resources. The patch also provides an addition to the OpenSBI domain to provide updates on hart-domain assignment and declarations of contexts within the domain.

lib: tests: Add sbi_console test

2024-03-10T04:42:52Z

Add the test suite covering some of the functions from lib/sbi/sbi_console.c: putc, puts and printf. The test covers a variety of format specifiers for printf and different strings and characters for putc and puts. In order to do that, the test "mocks" the sbi_console_device structure by setting the 'console_dev' variable to the virtual console. Signed-off-by: Ivan Orlov Reviewed-by: Andrew Jones

lib: Add SBIUnit testing macros and functions

2024-03-10T04:35:28Z

This patch introduces all of the SBIUnit macros and functions which can be used during the test development process. Also, it defines the 'run_all_tests' function, which is being called during the 'init_coldboot' right after printing the boot hart information. Also, add the CONFIG_SBIUNIT Kconfig entry in order to be able to turn the tests on and off. When the CONFIG_SBIUNIT is disabled, the tests and all related code is excluded completely on the compilation stage. Signed-off-by: Ivan Orlov Reviewed-by: Andrew Jones
