gjz010 da028c1f10 Added virtual memory support for aarch64 and x86_64. 1. Memory mapping at KSEG2_START(0xffff_fe80_0000_0000) will now be visible to all processes. This feature is required by Loadable Kernel Module when mapping kernel module into memory. 2. Wrapping PageTableImpl::active() into ManuallyDrop, so that no extra "mem::forget" is required. 3. Added PageTableImpl::kernel_table(). This function is the same as active() on x86_64, but not the same on aarch64.		2019-06-07 15:57:18 +08:00

rCore

Rust version of THU uCore OS Plus.

Going to be the next generation teaching operating system.

Supported architectures: x86_64, RISCV32/64, AArch64, MIPS32

Tested boards: QEMU, HiFive Unleashed, x86_64 PC (i5/i7), Raspberry Pi 3B+, Kendryte K210 and FPGA running Rocket Chip / TrivialMIPS

Building

Environment

Rust toolchain at nightly-2019-03-05
Cargo tools: cargo-xbuild
QEMU >= 3.1.0
bootimage (for x86_64)
RISCV64 GNU toolchain (for riscv32/64)
AArch64 GNU toolchain (for aarch64)
musl-cross-make (for userland musl, or download prebuilt toolchain from musl.cc)
libfuse-dev (for userland image generation)

See Travis script for details.

How to run

$ rustup component add rust-src llvm-tools-preview
$ cargo install cargo-binutils
$ cargo install cargo-xbuild --force
$ cargo install bootimage --version 0.5.7 --force

$ git clone https://github.com/rcore-os/rCore.git --recursive
$ cd rCore/user
$ make sfsimg arch={riscv32,riscv64,x86_64,aarch64,mipsel} # requires $(arch)-linux-musl-gcc
$ cd ../kernel
$ make run arch={riscv32,riscv64,x86_64,aarch64,mipsel} mode=release
$ make run arch=x86_64 mode=release pci_passthru=0000:00:00.1 # for ixgbe real nic, find its pci (bus, dev, func) first
