| 2026-04-24 | hypervisor: add tests for implicit G-stage faults during VS-stage walks (#651)HEADmaster | Nadime Barhoumi | 3 | -0/+252 | |
| Adds four RV64 hypervisor tests exercising implicit G-stage faults raised during VS-stage page table walks: - 2-stage_translation_implicit_load_error - 2-stage_translation_implicit_load_error_hs - 2-stage_translation_implicit_store_error - 2-stage_translation_implicit_store_error_hs The load variants trigger the fault by leaving the G-stage PTE invalid (no PTE_V), causing the implicit PTE read during the VS-stage walk to fault. The store variants omit PTE_W on the G-stage PTE, so G-stage grants read but denies write, causing the implicit PTE store for the A/D writeback to fail. These require hardware A/D updates, which occur when Svadu is enabled via ADUE. Each test checks mcause/scause, mtval/stval, and mtval2/htval and verifies that mtinst/htinst contains the expected pseudoinstruction: - 0x3000 — 64-bit implicit VS-stage PTE load - 0x3020 — 64-bit implicit VS-stage PTE store | |||||
