Oktatóanyag 02 - Többmagos C
|
||||
============================
|
||||
|
||||
Próbáljunk valami összetettebbet, mit szóltok? Összetettebb alatt azt értem, hogy most is megállítjuk a CPU magokat,
|
||||
akárcsak az első oktatóanyagban, de most az egyik magot C-ből!
|
||||
|
||||
Start
|
||||
-----
|
||||
|
||||
Most már meg kell különböztetnünk a magokat. Ehhez kiolvassuk a *mpidr_el1* rendszer regisztert. Ha nem nulla, akkor
|
||||
a korábbi végtelen ciklus következik. Ha nulla, akkor meg fogunk hívni egy C eljárást. De ehhez előbb be állítanunk
|
||||
egy megfelelő vermet, ki kell nulláznunk a bss szegmenst mielőtt kiadhatnánk az ugrás parancsot. Hozzáadtam néhány
|
||||
Assembly sort, amik mindezt elvégzik. Arra az esetre, ha a C eljárás visszatérne (nem szabadna), ugyanarra a
|
||||
végtelen ciklusra ugrunk, mint amit a többi CPU mag is épp végrehajt.
|
||||
|
||||
Makefile
|
||||
--------
|
||||
|
||||
Egy kisit trükkösebb lett. Hozzáadtam parancsokat a C fordításhoz, de akkor már általánosan. Mostantól ugyanazt
|
||||
a Makefile-t használhatjuk minden oktatóanyaghoz, függetlenül attól, hány C forrásfájlunk van, és a továbbiakban
|
||||
nem is szerepeltetem.
|
||||
|
||||
Linker script
|
||||
-------------
|
||||
|
||||
Hasonlóan, a linker szkript is bonyolultabbá vált, mivel a C-hez adat és bss szekciókra is szükség van. Hozzáadtam
|
||||
továbbá egy számolást a bss szegmens méretének megállapítására, így egyszerűen hivatkozhatunk rá Assembly-ben, és
|
||||
nem kell ott molyolni vele.
|
||||
|
||||
Fontos, hogy a text szegmens az Assembly kóddal kezdődjön, mivel ez elé raktuk a vermet, ezért kell a KEEP().
|
||||
Íly módon mind a betöltési címünk 0x80000, akárcsak a `_start` cimke címe és a verem teteje.
|
||||
|
||||
Main
|
||||
----
|
||||
|
||||
Végezetül, az első C kódunk. Csak egy végtelen ciklus, de akkor is! :-)

Tutorial 02 - Multicore C
|
||||
=========================
|
||||
|
||||
Now let's try something more complex, shall we? By complex I mean stop the CPU cores just like in the first tutorial,
|
||||
but this time stop one of them from C!
|
||||
|
||||
Start
|
||||
-----
|
||||
|
||||
Now we have to distinguish the cores. For that, we read the *mpidr_el1* system register. If it's not zero, we'll
|
||||
do the former infinite loop. If it's zero, then we'll call a C function. But for that, we need a proper stack, and a
|
||||
zerod out bss segment in memory before the call instruction. I've added some more code to the Assembly to do all of
|
||||
that. In case the C code returns (shouldn't), we also jump to the same infinite loop the other CPU cores running.
|
||||
|
||||
Makefile
|
||||
--------
|
||||
|
||||
It became a bit trickier. I've added commands for compiling C sources, but in a comform way. From now on, we
|
||||
can use the same Makefile for every tutorial, regardless of the number of C sources, and I won't discuss it any
|
||||
further.
|
||||
|
||||
Linker script
|
||||
-------------
|
||||
|
||||
Likewise, the linker script became more complex too, as C needs data and bss sections. I've also added a calculation
|
||||
for the bss size, so that we can refer to it from the Assembly without any further hassle.
|
||||
|
||||
It is important to start the text segment with the Assembly code, because we set the stack right before it, hence
|
||||
the KEEP(). This way our load address is 0x80000, the same as `_start` label and stack top.
|
||||
|
||||
Main
|
||||
----
|
||||
|
||||
Finaly, our first C code. Just an empty loop, but still! :-)

# Tutorial 02 - Multicore Rust
|
||||
|
||||
Now let's try something more complex, shall we? By complex I mean stopping the
|
||||
CPU cores just like in the first tutorial, but this time stop one of them from
|
||||
**Rust**!
|
||||
|
||||
## Glue code
|
||||
|
||||
In order to incorporate Rust code, we are setting up a binary crate and add
|
||||
`#![no_std]` to `main.rs`, since we are writing our own bare metal code and do
|
||||
not want to rely on the standard library.
|
||||
|
||||
However, a lot of steps are needed to make a `no_std` crate build. All of this
|
||||
and even more is explained in detail in [The Embedonomicon][nom], so please take
|
||||
your time and read up on it. Afterwards, you can compare to the files in this
|
||||
crate and see what we actually kept to get our Raspberry Pi 3 tutorial
|
||||
going. Here's a short summary of the crate's structure:
|
||||
|
||||
- `raspi3_glue/`: The extern crate containing glue code as presented in the
|
||||
Embedonomicon.
|
||||
- In a small deviation to the Embedonomicon, `lib.rs` also includes
|
||||
`_boot_cores.S` from the previous tutorial via the [global_asm!][gasm]
|
||||
macro.
|
||||
- Therefore, `_boot_cores.S` has been moved into `raspi3_glue/src/`.
|
||||
- `src`: Source code of our actual crate, currently only containing `main.rs`
|
||||
executing an endless loop.
|
||||
|
||||
[nom]: https://japaric.github.io/embedonomicon/
|
||||
[gasm]: https://doc.rust-lang.org/unstable-book/language-features/global-asm.html
|
||||
|
||||
### Changes to `_boot_cores.S`
|
||||
|
||||
In contrast to the previous tutorial, we now we have to [distinguish the
|
||||
cores][dist]. To do so, we read the [mpidr_el1][mpdir] system register. If it
|
||||
is not zero, we'll do the former infinite loop. If it is zero, aka we are
|
||||
executing on core0, then we'll call the Rust `reset()` function. For that, we
|
||||
also need a proper stack, and have space reserved in memory for the [bss
|
||||
segment][bss].
|
||||
|
||||
We added the `bss` segment to the linker script and export its properties via
|
||||
`__bss_start` and `__bss_size`, which will be picked up and zeroed out by the
|
||||
glue code in `raspi3_glue/src/lib.rs`. Additionally, we set the stack in the
|
||||
Assembly in `_boot_cores.S`, and then finally call the `reset()` function of the
|
||||
glue code, which in turn calls `main()` after zeroing `bss`. In case the Rust
|
||||
code returns (which it never should not), we also jump to the same infinite loop
|
||||
the other CPU cores running.

|
||||

|
||||
|
||||
## Changes to `Makefile`
|
||||
|
||||
It became a bit trickier. We've added more targets:
|
||||
- `kernel8.img` now depends on `kernel8`, which compiles the crate either in
|
||||
release or debug mode. For the latter, add `DEBUG=1` before invoking make,
|
||||
e.g. `DEBUG=1 make`
|
||||
- [clippy] is Rust's linter, and can give you useful advise to improve your
|
||||
code. Invoke with `make clippy`.
|
||||
|
||||
[clippy]: https://github.com/rust-lang-nursery/rust-clippy
|
||||
|
||||
From now on, we can use the same Makefile for every tutorial, regardless of the
|
||||
number of Rust sources, and we won't discuss it any further.
|
||||
|
||||
## Changes to `link.ld`
|
||||
|
||||
Apart from the added bss section, it is important to start the text segment with
|
||||
the Assembly code and not the Rust code, because we set the stack right before
|
||||
it, hence the `KEEP()`. This way, the assembly stays at 0x80000, the same as
|
||||
`_boot_cores` label and stack top.
|
||||
|
||||
## main.rs
|
||||
|
||||
Finally, our first Rust code. Just an empty loop, but still! :-)
