From 7509a4c89d581062dd405c53e1e7d8cae6dcf227 Mon Sep 17 00:00:00 2001 From: Jerin Joy Date: Thu, 25 Jul 2024 14:18:38 -0700 Subject: [PATCH 001/302] Added run_function_in_vumode(). We only support running this from VS-mode for now. This is similar to run_function_in_umode().

This is not needed anymore because generate_diag_sources.py will add a guard linker section after every linker section that isn't followed by another section. When a section is overrun and runs into the guard section the linker will fail the build. This test required num_pages_for_jumpstart_mmode_text to have more pages than were actually required just to so that it could build. We can now reduce num_pages_for_jumpstart_mmode_text.

The issue was fixed by: Changed chunk splitting condition from '>' to '>=' to allow splitting when we have exactly enough space for both the allocation and a new minimum segment. This ensures we don't miss opportunities to split chunks when we have precisely enough space available. This modification allows better utilization of heap space by enabling splits in cases where we have exactly enough space for both the allocation and a new minimum segment, rather than requiring strictly more space.

This manifest is passed to DiagFactory. Filter set: --include_diags and --exclude_diags allow selecting subsets when using a manifest. Batch mode: --batch_mode generates a combined manifest, payloads, and truf ELFs (qemu + fw-m only). Parallel jobs: -j/--jobs controls parallel compile concurrency (default 5). Improved the overrides flow. Improved the build summary. Input is now a mutually exclusive choice: one or more --diag_src_dir entries or a --build_manifest (required). Include/exclude flags are only valid with --build_manifest.

Allows us to create auto-expanding mappings based on active number of cpus. This allows us to write easily expandable diags that can extend to any number of cores if written with consideration. Couple of such examples can be found in ctest/diags/interrupts/ and ctest/diag/isa/fence_s. This avoids the need to go and update mappings when a diag active_hart_mask is overwritten.

Changes: - Add CStructField, CStruct, and MemoryOp classes to generate_diag_sources.py - Add generate_cstructs_defines(), generate_cstructs_data_structures(), and generate_cstructs_assembly() methods - Add --output_data_structures_file argument to generate separate .h files - Update meson.build to include data_structures.h in compilation - Add memory mapping validation for C struct regions - Remove C struct generation from generate_jumpstart_sources.py This consolidation allows C structs to be generated per-diagnostic rather than globally.

Changes: - Remove max_num_cpus_supported from both public and rivos_internal YAML files - Calculate max_num_cpus_supported dynamically using BitField.find_highest_set_bit() - Update primary_cpu_id calculation to use BitField.find_lowest_set_bit() - Replace all references to self.jumpstart_source_attributes["max_num_cpus_supported"] with self.max_num_cpus_supported throughout the codebase - Maintain the existing limit check (max_num_cpus_supported > 4) The system now automatically determines the maximum number of supported CPUs based on the highest set bit in the active_cpu_mask.
