From a6ecb0c4e9bb06c6348d51dfa2bc2aa8a602d2b1 Mon Sep 17 00:00:00 2001 From: ChinYikMing Date: Sun, 15 Dec 2024 00:02:05 +0800 Subject: [PATCH 1/5] Bring up Linux kernel The 8250 UART and PLIC peripherals, defined in src/devices/uart.[ch] and src/devices/plic.[ch], have been integrated. Modifications to src/system.c enable MMIO read and write operations for these peripherals. The minimal device tree source file is also integrated in src/devices/minimal.dts. Default termios control flags are set to ICANON | ECHO | ISIG, allowing all keyboard input to be captured by the guestOS. The CLI parser has been updated to support custom Linux Kernel Images, rootfs, and Device Tree Blobs. The ELF_LOADER has been introduced to support test suites involving single ELF files that use the rv32emu built-in syscall. It helps to choose the right executable loader and requires differentiation from guestOS syscalls. The csrrw instruction is now branchable since it may overwrite the SATP CSR during guestOS process scheduling. last_pc and is_branch_taken are now updated only when not in a trapped state, otherwise might lost the original state of them. A system make target has been added to simplify running system emulation. Misc changes: - Rename 'ARRAYS_SIZE' to 'ARRAY_SIZE' for better readability - Move JIT related variables to proper conditional build flag --- Makefile | 35 +++-- mk/artifact.mk | 36 ++++- mk/system.mk | 28 ++++ src/common.h | 59 +++++++- src/decode.h | 2 +- src/devices/minimal.dts | 69 +++++++++ src/devices/plic.c | 91 ++++++++++++ src/devices/plic.h | 41 ++++++ src/devices/uart.c | 151 +++++++++++++++++++ src/devices/uart.h | 51 +++++++ src/emulate.c | 130 ++++++++++++++-- src/feature.h | 5 + src/io.h | 1 + src/jit.c | 18 +-- src/main.c | 58 ++++++-- src/riscv.c | 317 ++++++++++++++++++++++++++++++---------- src/riscv.h | 89 ++++++----- src/riscv_private.h | 4 +- src/rv32_template.c | 271 ++++++++++++++++++++++++---------- src/system.c | 295 +++++++++++++++++++++++++++---------- tools/rv_histogram.c | 4 +- 21 files changed, 1431 insertions(+), 324 deletions(-) create mode 100644 mk/system.mk create mode 100644 src/devices/minimal.dts create mode 100644 src/devices/plic.c create mode 100644 src/devices/plic.h create mode 100644 src/devices/uart.c create mode 100644 src/devices/uart.h diff --git a/Makefile b/Makefile index 7feca7e3..79253124 100644 --- a/Makefile +++ b/Makefile @@ -9,8 +9,16 @@ CONFIG_FILE := $(OUT)/.config CFLAGS = -std=gnu99 -O2 -Wall -Wextra CFLAGS += -Wno-unused-label -CFLAGS += -include src/common.h +CFLAGS += -include src/common.h -Isrc/ +# In the system test suite, the executable is an ELF file (e.g., MMU). +# However, the Linux kernel emulation includes the Image, DT, and +# root filesystem (rootfs).

The mk/external.mk functions has been updated to enable downloading via 'git clone' and verifying the downloaded files excluding the git-related files. The Linux kernel image and Buildroot version are controlled in mk/external.mk, when the LINUX_VERSION or BUILDROOT_VERSION changes, the new Linux kernel image and rootfs.cpio are built and pushed to the rv32emu-prebuilt repository, the user ELF executables and system image are identified by suffix 'ELF' and 'Linux-Image' at release of rv32emu-prebuilt repository. Additionally, a 'build-linux-image' make target has been introduced to simplify the cloning and automatic building process. --- .github/workflows/build-artifact.yml | 60 +-
