Project:Branches: gedare/rtems:riscv-satp-init to rtems/rtos/rtems:main Author: Gedare Bloom ## Summary Add basic support for MMU. Closes #5540 ## Testing I have to hunt down the `spconsole01.exe` failure. It's probably an issue with the mmio register r/w access sync'ing. ### Uniprocessor s-mode config.ini: ``` [riscv/rv64imafdc_s] INHERIT = rv64imafdc RISCV_RAM_REGION_BEGIN = 0x84000000 RISCV_RAM_REGION_SIZE = 0x03000000 RISCV_USE_S_MODE = True ``` Tester ``` rtems-test --rtems-bsp=rv64imafdc_smode build/riscv/rv64imafdc_s/testsuites/sptests ... Passed: 221 Failed: 1 User Input: 0 Expected Fail: 0 Indeterminate: 0 Benchmark: 0 Timeout: 1 Test too long: 0 Invalid: 0 Wrong Version: 0 Wrong Build: 0 Wrong Tools: 0 Wrong Header: 0 ------------------ Total: 223 Failures: sp69.exe Timeouts: spconsole01.exe ``` ### SMP s-mode ``` [riscv/rv64imafdc_s_smp] INHERIT = rv64imafdc_s RTEMS_SMP = True ``` ``` rtems-test --rtems-bsp=rv64imafdc_smode_smp build/riscv/rv64imafdc_s_smp/testsuites/smptests ... Passed: 58 Failed: 2 User Input: 0 Expected Fail: 0 Indeterminate: 0 Benchmark: 0 Timeout: 0 Test too long: 0 Invalid: 0 Wrong Version: 0 Wrong Build: 0 Wrong Tools: 0 Wrong Header: 0 ----------------- Total: 60 Failures: smpmrsp01.exe smpschededf01.exe ``` These more or less match the results for SMP with M-Mode (it fails on smpfatal01.exe but not smpschededf01.exe). ## Generative AI I used ChatGPT to help debug the page table walk. It was an exciting adventure.
