[Buildroot] [v1 0/4] [PATCH 0/3] Add support for Pi5

[Buildroot] [v1 0/4] [PATCH 0/3] Add support for Pi5

[Gaël PORTAY]

Dear maintainers,

This patch series adds the support for the Raspberry Pi 5[0].

The first patch enables MMU 16K page-size on ARM64 as the Raspberry Pi 5
supports 16K page-size[1].

The two following patches bump the packages rpi-firmware and linux.
 - The package rpi-firmware bumps the dtb overlays to the commit
   7e9c2063fc15274fbc4dab1ca614f9228834d881[2]. The commit states "Add
   support for PI 5" and it bumps the kernel files. The firmware files
   transferred to the VideoCore GPU are left untouched since they are
   self-contained in the bootloader EEPROM of the Raspberry Pi 5
   firmware[3].
 - The package linux bumps to the raspberrypi kernel to 6.1.55 up to the
   commit[4]. The branch rpi-6.1.y supports the Raspberry Pi 5.

The last patch adds the raspberrypi5_defconfig for the Raspberry Pi 5
64-bit. It uses the defconfig bcm2712_defconfig[5] and the device-tree
source bcm2712-rpi-5-b.dts[6]. The Raspberry Pi 5 has now a dedicated
debug UART connector[7] (it is always active and enabled; there is no
more need to enable_uart=1 in the file config.txt). The UART device name
changes to ttyAMA10 and the command line has to be updated in the file
cmdline.txt. The Raspberry Pi 5 only supports 64-bit kernel[8].

The output boots fine and it runs getty on uart and virtual tty if it is
built using the toolchain built by buildroot.

The output boots the kernel but the kernel cannot run the init process
if it is built using the bootlin prebuilt toolchain. Something is broken
due to the 16k MMU page-size :(

Question: the device-tree overlays are taken from the rpi-firmware; is
there a plan to compile the one from the downstream kernel sources
instead? by tweaking the linux.mk maybe?

Changes since RFC:
 - Update README to add model Pi 5 B
 - Add support for 64K MMU page-size for ARM64 and Raspberry Pi 5
 - Add Raspberry Pi 5 specific cmdline_5.txt to set its console on its
   debug uart (ttyAMA10 instead of ttyAMA0)
 - Remove 32-bit variant since Raspberry Pi 5 supports booting a 64-bit
   kernel only
 - Remove the property arm_64bit=1 from config_5_64bit.txt
 - Remove the _64bit suffix
 - Remove unecessary Pi 5 variant from package rpi-firmware

We are now using a version more recent than that (that you also
submitted), so I marked this a not-applicable.

Thanks!

Re: [Buildroot] [v1 3/4] configs/raspberrypi*: bump kernel version to feb4ea5 (6.1.55)

[Giulio Benetti]

Hi Gaël,

unfortunately this patch has been superseded by the following one that's
been committed:
https://gitlab.com/buildroot.org/buildroot/-/commit/13ba668a2da3a0dcb386578ce15b00a444101dbe

So it can be dropped from Patchwork.

Best regards

I've found that BCM2712 is a quad-cortex A76 and not A76+A55, so if I'm
correct with BCM2712 on Raspberry 5 SoC model you should enable:
BR2_cortex_a76=y

> +BR2_ARM_FPU_VFPV4=y

I can't find informations on which type of FPU implementation BCM2712
has but here:
https://en.wikipedia.org/wiki/Raspberry_Pi
I see:
that all Raspberry up to version 4 support VFPV4 so it makes sense to
enable VFPV4.
Have you tested some package that uses FPU extensively?

I *think* this is expected. The Bootlin toolchains are built for the
default page size of 4KB, so the libc in those toolchains expects 4KB
pages, and this breaks if you mix it with code that was built for 16 KB
page size.

The problem here is that it would be a tweak in linux.mk that is
specific to how the downstream RPi kernel does it. But the mainline
kernel has grown support for building DT overlays too. Is it similar to
how the downstream RPi kernel does it?

Which tweak would be needed in linux.mk to build overlays in the
downstream RPi kernel?

Okay. So it needs to ship multiple toolchains, one per page-size? Or
maybe there is a compiler flag or whatsoever; I saw a linker flag. I
know nothing about that for now. I need to dig in.

BTW, I wonder how the Raspberry OS deals with an image working for both
4k and 16k in a single userland; maybe it is just a matter of toolchain.

All I know for know is that upstream sets the flag -@ to embed the nodes
__symbols__ and __local_fixups__ in the dtb subject to get overlaid at
runtime.

The dtbo can resolve its missing symbols from its node __fixups__ then
IIRC.

Did I missed something new in the upstream kernel?

> Which tweak would be needed in linux.mk to build overlays in the

In fact, the overlays are built already by linux.mk since it builds the
device-trees and thus the overlays at the same time.

Actually, there is no mecanism to install them back the output directory
since the linux.mk does not use the target dtbs_install to install the
device-tree blobs.

It uses BR2_LINUX_KERNEL_INTREE_DTS_NAME to list the in-tree device-tree
to install manually thanks to an install -D.

Therefore, the overlays need the same mecanism for the overlays.

Note: The mecanism cannot be reused for the overlays since the name
given is the path:
 - from the dts directory (overlays are in overlays/)
 - without the .dts suffix (overlays have -overlay.dts)
 - .dtb is automatically suffixed (/!\ overlays have -overlay.dtbo)

I have already made that tweak but I have not submitted it for an RFC as
the overlays is a downstream specific feature (at least for now), and I
do not know if another downstream kernel tree builts overlays.

Therefore, I think it should not be a part of linux.mk (at least
directly), even if it is standard with other downstream trees.

Below is a part of the tweak I am thinking about (it is a copy/paste of
what it is done for dts/dtb):

I have just tested with the toolchain "Arm AArch64 12.2.rel1" and it
works! It is just a matter of toolchain.
