Use lateout nomem etc.

This function should just initialize.

CR2 register contains the physical address of PML4, not the virtual one.

Dereferencing drops the old value. If the memory are not initialized, undefined behavior may happen.

Running cargo build unconditionally seems the best way to solve.

For exmple, Size.

Not to write any additional lines in Makefile.

This function should be separated into two: actual putting data, and return bool value which represents whether three bytes data are sent or not.

The content of this module can be moved to main.rs.

Dependabot couldn't find a Cargo.toml for this project.

Dependabot requires a Cargo.toml to evaluate your project's current Rust dependencies. It had expected to find one at the path: /Cargo.toml.

If this isn't a Rust project, or if it is a library, you may wish to disable updates for it from within Dependabot.

Set 511st index of PML4.

All predefined addresses and sizes should be in this file.

Usually SystemTable is not needed. Rather, BootServices is used.

asm module should contain only general-purpose functions like in, out.

This may be possible using subcrate, then add a dependency.

These functions should be refactored to remove duplications.

Check descriptor.page_count > 0.

There seems no way to get the number of bytes .bss section consumes. Also, there are lots of useful tools to analyze the ELF binary.

Conversion table can be seen as a large slice whose element's type is usize.

You no longer need cargo-xbuild. Also, you can run RamenOS without installing it on USB memory. Instead you can boot on QEMU. Add an instruction to run RamenOS on QEMU.

Remove function callings.

Branch if accessing to USB_DEVICE needs sudo.

This is reminiscent of Haribote OS, isn't it?

Currently if some files in bootx64 directory are changed, make will not recompile. This will cause overlooking some bugs.

Rename this to lidt.

Currently the type of Device.data is u32. The possible values are 0, 1, 2, or 3. Define Enum value to limit the possible values.

If OS panics between after exiting it and before jumping to the kernel, no error messages will be printed.

At least separate this file into two: getting memory map and initializing paging.

Caller function should come before callee functions.

Use type.

Equivalent as make release && make run

Is the order to call these functions important? What do the numbers mean?

Our bootx64 doesn't handle the other files than the kernel.

This is not about "memory map", so this should be renamed.

To detect invalid memory accesses easily.
