This patch series adds support for the kv3-1 CPU architecture of the kvx family
found in the Coolidge (aka MPPA3-80) SoC of Kalray.
This is an RFC, since kvx support is not yet upstreamed into gcc/binutils,
therefore this patch series cannot be merged into Linux for now.
The goal is to have preliminary reviews and to fix problems early.
The Kalray VLIW processor family (kvx) has the following features:
* 32/64 bits execution mode
* 6-issue VLIW architecture
* 64 x 64bits general purpose registers
* SIMD instructions
* little-endian
* deep learning co-processor
Kalray kv3-1 core which is the third of the kvx family is embedded in Kalray
Coolidge SoC currently used on K200 and K200-LP boards.
The Coolidge SoC contains 5 clusters each of which is made of:
* 4MiB of on-chip memory (SMEM)
* 1 dedicated safety/security core (kv3-1 core).
* 16 PEs (Processing Elements) (kv3-1 cores).
* 16 Co-processors (one per PE)
* 2 Crypto accelerators
The Coolidge SoC contains the following features:
* 5 Clusters
* 2 100G Ethernet controllers
* 8 PCIe GEN4 controllers (Root Complex and Endpoint capable)
* 2 USB 2.0 controllers
* 1 Octal SPI-NOR flash controller
* 1 eMMC controller
* 3 Quad SPI controllers
* 6 UART
* 5 I2C controllers (3 of which are SMBus capable)
* 4 CAN controllers
* 1 OTP memory
A kvx toolchain can be built using:
# install dependencies: texinfo bison flex libgmp-dev libmpc-dev libmpfr-dev
$ git clone https://github.com/kalray/build-scripts
$ cd build-scripts
$ source last.refs
$ ./build-kvx-xgcc.sh output
The kvx toolchain will be installed in the "output" directory.
A buildroot image (kernel+rootfs) and toolchain can be built using:
$ git clone -b coolidge-for-upstream https://github.com/kalray/buildroot
$ cd buildroot
$ make O=build_kvx kvx_defconfig
$ make O=build_kvx
The vmlinux image can be found in buildroot/build_kvx/images/vmlinux.
If you are just interested in building the Linux kernel with no rootfs you can
just do this with the kvx-elf- toolchain:
$ make ARCH=kvx O=build_kvx CROSS_COMPILE=kvx-elf- default_defconfig
$ make ARCH=kvx O=build_kvx CROSS_COMPILE=kvx-elf- -j$(($(nproc) + 1))
The vmlinux ELF can be run with qemu by doing:
# install dependencies: ninja pkg-config libglib-2.0-dev cmake libfdt-dev libpixman-1-dev zlib1g-dev
$ git clone https://github.com/kalray/qemu-builder
$ cd qemu-builder
$ git submodule update --init
$ make -j$(($(nproc) + 1))
$ ./qemu-system-kvx -m 1024 -nographic -kernel <path/to/vmlinux>

+* Kalray kvx Performance Monitors
+
+KVX core has several Performance Monitors for counting cpu and cache events.
+The KVX PM representation in the device tree should be done as under:
+
+Required properties:
+
+- compatible :
+ "kalray,kvx-core-pm"
+
+- interrupts : The interrupt number for kvx PM is 3.
+- interrupt-parent : The kvx core interrupt controller.
+- kalray,pm-num : Number of Performance Monitors the kvx core has.
+
+Example:
+core_pm {
+ compatible = "kalray,kvx-core-pm";
+ interrupts = <3>;
+ interrupt-parent = <&core_intc>;
+ kalray,pm-num = <4>;
+}

You should strip this series down to just what's needed to boot. You
don't need the last 7 patches at least.

Thanks for posting these, I had been wondering about the
state of the port. Overall this looks really nice, I can
see that you and the team have looked at other ports
and generally made the right decisions.
I commented on the syscall patch directly, I think it's
important to stop using the deprecated syscalls as soon
as possible to avoid having dependencies in too many
libc binaries. Almost everything else can be changed
easily as you get closer to upstream inclusion.
I did not receive most of the other patches as I'm
not subscribed to all the mainline lists. For future
submissions, can you add the linux-arch list to Cc for
all patches?
Reading the rest of the series through lore.kernel.org,
most of the comments I have are for improvements that
you may find valuable rather than serious mistakes:
- the {copy_to,copy_from,clear}_user functions are
well worth optimizing better than the byte-at-a-time
version you have, even just a C version built around
your __get_user/__put_user inline asm should help, and
could be added to lib/usercopy.c.
- The __raw_{read,write}{b,w,l,q} helpers should
normally be defined as inline asm instead of
volatile pointer dereferences, I've seen cases where
the compiler ends up splitting the access or does
other things you may not want on MMIO areas.
- I would recomment implementing HAVE_ARCH_VMAP_STACK
as well as IRQ stacks, both of these help to
avoid data corruption from stack overflow that you
will eventually run into.
- You use qspinlock as the only available spinlock
implementation, but only support running on a
single cluster of 16 cores. It may help to use
the generic ticket spinlock instead, or leave it
as a Kconfig option, in particular since you only
have the emulated xchg16() atomic for qspinlock.
- Your defconfig file enables CONFIG_EMBEDDED, which
in turn enables CONFIG_EXPERT. This is probably
not what you want, so better turn off both of these.
- The GENERIC_CALIBRATE_DELAY should not be necessary
since you have a get_cycles() based delay loop.
Just set loops_per_jiffy to the correct value based
on the frequency of the cycle counter, to save
a little time during boot and get a more accurate
delay loop.

Thank you and all for the reviews. We are currently going
through every remarks and we are trying to do our best to
send a new patch series with everything addressed.

We misused get_maintainers.pl, running it on each patch instead
of using it on the whole series. next time every one will be in
copy of every patch in the series and including linux-arch.

right, we are using memcpy for {copy_to,copy_from}_user_page
which has a simple optimized version introduced in
(kvx: Add some library functions).
I wonder if it is possible to do the same for copy_*_user functions.

Be careful not to make the list too long though, there is
usually a limit of 1024 characters for the entire Cc list,
above this your mails may get dropped by the mailing lists.

copy_from_user_page() is only about managing cache aliases,
not user access, and it's not used anywhere in the fast
path, so it's a bit different.
arch/arm/lib/copy_template.S has an example for how
you can share the same assembler implementation between
memcpy() and copy_from_user(), but it's not very
intuitive.
The tricky bit with copy_from_user() is the partial copy
that relies on copying the exact amount of data that can
be accessed including the last byte before the end of
the mapping, and returning the correct count of non-copied
bytes.
If you want a C version, you can probably use the
copy_from_kernel_nofault implementation mm/maccess.c
as a template, but have to add code for the correct
return value.

It's best to include mailing lists for the entire series, and perhaps
individuals for each patch. As I don't want the entire series just to see
the tracing portion.

I would like to build the kvx-xgcc to compile and test the linux
kernel, but it reported a compile error.
I wonder what version of gcc you are using.
My build environment:
VERSION="20.04.2 LTS (Focal Fossa)"
gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04)
Compile error:
$ ./build-kvx-xgcc.sh output

What SHA1 of https://github.com/kalray/build-scripts are you using?
We are building our toolchain on Ubuntu 18.04 / 20.04 and 22.04 without
issues, I don't understand why it does not work for you, although indeed
the error log you are having pops out on my search engine and seems to
be some well known issue.
If the build-script does not work for you, you can still use the
pre-built toolchains generated by the GitHub automated actions:
https://github.com/kalray/build-scripts/releases/tag/v4.11.1 ("latest"
means 22.04)
I hope it will work for you.
Regards,

Yes, there are many answers on the web, but none of them solve this problem.

I was referring to the SHA1 of the repo itself (build-scripts).
`last.refs` is a symbolic link which can point to several releases,
depending on "when" you did the clone.
I am asking this because we recently published new toolchains.
I want to make sure which one you are trying to build.

Unfortunately I deleted this repo a few minutes before you asked me ;-(
But I remember that I cloned this repo two days ago.
it should be: last.refs -> refs/4.11.0.refs
