This series adds tests for SBI SSE extension as well as needed infrastructure for SSE support. It also adds test specific asm-offsets generation to use custom OFFSET and DEFINE from the test directory. These tests can be run using an OpenSBI version that implements latest specifications modification [1] Link: https://github.com/rivosinc/opensbi/tree/dev/cleger/sse [1] --- V11: - Use mask inside sbi_impl_opensbi_mk_version() - Mask the SBI version with a new mask - Use assert inside sbi_get_impl_id/version() - Remove sbi_check_impl() - Increase completion timeout as events failed completing under 1000 micros when system is loaded. V10: - Use && instead of || for timeout handling - Add SBI patches which introduce function to get implementer ID and version as well as implementer ID defines. - Skip injection tests in OpenSBI < v1.6 V9: - Use __ASSEMBLER__ instead of __ASSEMBLY__ - Remove extra spaces - Use assert to check global event in sse_global_event_set_current_hart() - Tabulate SSE events names table - Use sbi_sse_register() instead of sbi_sse_register_raw() in error testing - Move a report_pass() out of error path - Rework all injection tests with better error handling - Use an env var for sse event completion timeout - Add timeout for some potentially infinite while() loops V8: - Short circuit current event tests if failure happens - Remove SSE from all report strings - Indent .prio field - Add cpu_relax()/smp_rmb() where needed - Add timeout for global event ENABLED state check - Added BIT(32) aliases tests for attribute/event_id. V7: - Test ids/attributes/attributes count > 32 bits - Rename all SSE function to sbi_sse_* - Use event_id instead of event/evt - Factorize read/write test - Use virt_to_phys() for attributes read/write. - Extensively use sbiret_report_error() - Change check function return values to bool. - Added assert for stack size to be below or equal to PAGE_SIZE - Use en env variable for the maximum hart ID - Check that individual read from attributes matches the multiple attributes read. - Added multiple attributes write at once - Used READ_ONCE/WRITE_ONCE - Inject all local event at once rather than looping fopr each core. - Split test_arg for local_dispatch test so that all CPUs can run at once. - Move SSE entry and generic code to lib/riscv for other tests - Fix unmask/mask state checking V6: - Add missing $(generated-file) dependencies for "-deps" objects - Split SSE entry from sbi-asm.S to sse-asm.S and all SSE core functions since it will be useful for other tests as well (dbltrp). V5: - Update event ranges based on latest spec - Rename asm-offset-test.c to sbi-asm-offset.c V4: - Fix typo sbi_ext_ss_fid -> sbi_ext_sse_fid - Add proper asm-offset generation for tests - Move SSE specific file from lib/riscv to riscv/ V3: - Add -deps variable for test specific dependencies - Fix formatting errors/typo in sbi.h - Add missing double trap event - Alphabetize sbi-sse.c includes - Fix a6 content after unmasking event - Add SSE HART_MASK/UNMASK test - Use mv instead of move - move sbi_check_sse() definition in sbi.c - Remove sbi_sse test from unitests.cfg V2: - Rebased on origin/master and integrate it into sbi.c tests Clément Léger (8): kbuild: Allow multiple asm-offsets file to be generated riscv: Set .aux.o files as .PRECIOUS riscv: Use asm-offsets to generate SBI_EXT_HSM values lib: riscv: Add functions for version checking lib: riscv: Add functions to get implementer ID and version riscv: lib: Add SBI SSE extension definitions lib: riscv: Add SBI SSE support riscv: sbi: Add SSE extension tests scripts/asm-offsets.mak | 22 +- riscv/Makefile | 5 +- lib/riscv/asm/csr.h | 1 + lib/riscv/asm/sbi.h | 177 +++++- lib/riscv/sbi-sse-asm.S | 102 ++++ lib/riscv/asm-offsets.c | 9 + lib/riscv/sbi.c | 105 +++- riscv/sbi-tests.h | 1 + riscv/sbi-asm.S | 6 +- riscv/sbi-asm-offsets.c | 11 + riscv/sbi-sse.c | 1278 +++++++++++++++++++++++++++++++++++++++ riscv/sbi.c | 2 + riscv/.gitignore | 1 + 13 files changed, 1707 insertions(+), 13 deletions(-) create mode 100644 lib/riscv/sbi-sse-asm.S create mode 100644 riscv/sbi-asm-offsets.c create mode 100644 riscv/sbi-sse.c create mode 100644 riscv/.gitignore -- 2.47.2
