Add Intel Arc A750

[geerlingguy]

I am testing an Intel Arc A750 8GB graphics card:

It requires external PCIe power, so needs to be used with a suitable power supply. Intel seems to only officially support Ubuntu 22.04, and by default only AMD64/x86_64... Here's the full Ubuntu installation guide for Arc drivers.

Not sure if I can get it to work at all on Debian, and I also haven't confirmed if aarch64/ARM64 support is at all existing, planned, or not planned. Would like to find out, because I'll soon have another ARM64 system to test this in with a bit more firepower.

See also: Intel Arc Graphics A750/A770 Performance Ahead Of Linux 6.2 + Mesa 23.0 — it may be possible if the Pi OS kernel is up to 6.2 (it was 6.1 last time I checked) to compile the driver and see what happens.

There's a good deal of coil whine on my card—when testing on the PC and it needs to render anything. At idle there isn't much, but when the fans stop spinning and the card is not displaying anything, or alternatively when the GPU is under heavy load, there's a lot of coil whine, enough to be pretty distracting.

On Twitter someone mentioned this commit: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/drivers/gpu/drm/i915/Kconfig?h=next-20230210 — it looks like the i915 has some hardcoded x86 dependencies:

# SPDX-License-Identifier: GPL-2.0-only

    depends on DRM
    depends on X86 && PCI

[geerlingguy]

To test out Intel's open source kernel driver, I cloned the 6.2.y branch of Raspberry Pi's linux fork:

git clone -b rpi-6.2.y https://github.com/raspberrypi/linux.git && cd linux
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bcm2711_defconfig
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- menuconfig
  # Enable the i915 driver

I asked about arm/arm64/aarch64 support on Intel Arc/Xe on Twitter and got a few responses, mostly suggesting X86 drivers are the current focus, but they may rewrite the driver and work on getting rid of the X86-specific dependencies...

I also asked about it on Discord, but I noticed most of the active discussion (on Intel's official Arc/Xe community Discord) seems to center around where people can buy Nvidia graphics cards 🤣

The only other mention on Twitter is from @ric96, and he also seems to notice there's no support for arm64...

[Mis012]

Just FYI, the most likely reason x86 is listed as a dependency is that historically Intel only had iGPUs, and those can't exactly be plugged into an aarch64 system for obvious reasons. That being said, it seems quite likely that if those dependencies were removed (since they are for all we know completely bogus), chances are the driver would actually compile just fine. It seems quite unlikely that it uses assembly for anything, which is just about the only valid reason for it to not compile for aarch64

[pimzand]

It looks like you could try again with Xe drivers in kernel 6.8: https://www.phoronix.com/review/intel-xe-benchmark

[DanaGoyette]

If you do decide to test this with 6.8, note that Ubuntu's Mesa doesn't have the Intel drivers enabled, and even if you check out the experimental branch of the mesa packaging from debian's "salsa" repo, it doesn't enable the Intel drivers for armhf or arm64/aarch64. You'll want to edit debian/rules:

   # etnaviv, tegra, vc4 and v3d kernel support are only available on armhf and arm64
   ifneq (,$(filter $(DEB_HOST_ARCH), armhf arm64))
-       GALLIUM_DRIVERS += etnaviv panfrost svga tegra vc4 v3d
-       VULKAN_DRIVERS += broadcom freedreno
+       GALLIUM_DRIVERS += iris etnaviv panfrost svga tegra vc4 v3d
+       VULKAN_DRIVERS += intel broadcom freedreno
   endif

On my LX2160A, the kernel driver for my A770 loads once I add xe.force_probe=56a0. It complains about lack of resizable BAR, though. With a manually rebuilt Mesa, Weston works, but gdm3 and sddm both glitch out and freeze, and autologin doesn't give a working desktop either.

[ 4908.679401] xe 0004:03:00.0: [drm] Engine reset: guc_id=7

If you can get the driver to work without glitching out, you'll also run into these chirping crickets: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/234

(I actually bought the A770 to use with arm64, but now it's just sitting unused.)

[karatekid430]

Only slightly related but if anybody working for Intel is reading this, please note the new arm64 laptops all support USB4 / Thunderbolt and if Intel can release GPU drivers for these for arm64 Windows 11 and arm64 Linux then we would love that for eGPUs! Running a fast and efficient Snapdragon Elite X and then using eGPU for gaming or rendering would be amazing!

[geerlingguy]

@karatekid430 - Sadly, arm64 driver support on Windows for anything besides USB devices is pretty much nonexistent so far. I'm not sure if any graphics card (let alone NICs and other simpler devices) will support PCIe (especially through Thunderbolt/external enclosures) any time soon. Would love to be proven wrong on that!

xe drivers built, updated firmware. booted and it detected the card, need more time to trace into the root cause.

note: i use the RPi 6.11.y , turn the intel xe on via make menuconfig, and force it to probe the vid/pid (i manually add it in the .config) and update the firmware manually (got it from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-20241110.tar.gz )

[geerlingguy]

@martinx72 Excited to re-open this issue ;)

[pimzand]

Fedora 41 for aarch64 has xe kernel support out of the box.

[martinx72]

Fedora 41 for aarch64 has xe kernel support out of the box.

@pimzand Does this release support Pi 5?

And some more progress here, at least no crash in the driver

Page Size set as 4K, then it went to some error much easier for me to narrow down the crash issue, but, i think i probably have to stop here. As intel keep modifying their repo every single day here: https://gitlab.freedesktop.org/drm/xe/kernel

IMO, never can chase their steps by myself. :(

[pimzand]

@pimzand Does this release support Pi 5?

Not fully, apparently: https://discussion.fedoraproject.org/t/aarch64-support-for-raspberry-pi-5/134857

I tried an Arc 310 Eco in an Ampere Altra system while still Fedora 40. Xe support was introduced with F40 kernel 6.11. The driver loaded without errors, but the screen stayed black.

Just check the link in the post, https://rpmfusion.org/Howto/RaspberryPi It says 'using Raspberry Pi Foundation downstream kernel and components from Fedora userspace.'

Then it is 6.6,y, and it never can boot with xe drive at all.

[DanaGoyette]

@karatekid430 - Sadly, arm64 driver support on Windows for anything besides USB devices is pretty much nonexistent so far. I'm not sure if any graphics card (let alone NICs and other simpler devices) will support PCIe (especially through Thunderbolt/external enclosures) any time soon. Would love to be proven wrong on that!

Intel doesn't have any ARM64 Windows drivers for any of their NICs I've checked. NVIDIA/Mellanox, on the other hand, does have in-the-box ARM64 Windows drivers for ConnectX-4 and newer.

I've used a Mellanox ConnectX-4 Lx 10-/25-gigabit ethernet NIC with my Snapdragon X machine on Windows ARM64, via USB4 / Thunderbolt. It works, but oddly, one direction seems to give only 5 gigabits of throughput for some reason.

As far as I can tell, there are no discrete GPU drivers for Windows ARM64. On ARM64 machines with UEFI, such as LX2160A, the closest you can get is loading AMD's GOP driver in UEFI to run the framebuffer with Microsoft Basic Graphics Adapter.

[geerlingguy]

@DanaGoyette From what I've heard, Nvidia may have working drivers for Windows arm64, as they've worked on support for enterprise use in Azure... at least that's what I infer from tweets like this.

[pepijndevos]

I see some fairly similar but different issues to what @martinx72 was seeing in their issue tracker, maybe worth reporting? https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/3074

[FibreFoX]

@martinx72 Can you add some steps, what you've done so far? Like what RaspiOS are you using, and are you trying X11 or Wayland? So far I understand you compiled the 6.11.y branch, selected Intel XE via menuconfig and added some firmware binaries to it. Did you, by any chance, create some small script to do all of that?

I have a spare 8GB Raspi5 with a spare Intel Arc 770 here for some experiments, maybe I can help, even tho I am very new to the kernel hacking game.

Check the way to build kernel for Pi5 aarch64: https://www.raspberrypi.com/documentation/computers/linux_kernel.html just few commands to type, i believe you dont need any script just for building the kernel

And use make menuconfig to enable the intel Xe driver, and pagesize as 4K. that's all.

And you can also try 6.12.y, i tried both, all crashed there. and u can also try the intel xe driver source stream here: https://gitlab.freedesktop.org/drm/xe/kernel

[pepijndevos]

There are a few more menuconfig entries in the AMD article that could be worth trying https://www.jeffgeerling.com/blog/2024/amd-radeon-pro-w7700-running-on-raspberry-pi

[FibreFoX]

So far using a very naive approach does not bring me very far. I am using the current 6.12.y branch of the raspberry kernel and starting with a fresh installation of Raspberry Pi OS (64bit, desktop).

Some commands I am using as root user:

# making sure to have up2date system
apt-get update
apt upgrade

# installing some build dependencies (might contain unneeded stuff, copy-pasted a lot from several of my own projects)
apt-get install -y bc bison flex libssl-dev make git
apt-get install -y libncurses5-dev
apt-get install -y xz-utils kmod
apt-get install -y libelf-dev libssl-dev

# clone the raspberry kernel, at time of writing at commit 05678eba0b1fc51355b03b0d3f05f059068baf3e
cd /opt
git clone --depth=1 --branch rpi-6.12.y https://github.com/raspberrypi/linux
cd linux

# adjusting kernel compile configuration
make bcm2712_defconfig
make menuconfig

Then I select the following options (the ones from the AMD article are not there, because the kernel-fork introduces them):

# Kernel Features > Page Size > 4 KB
# Kernel Features > Virtual address space size > 48-bit (had to change this in a different project, so I hoped this would help too)
# Kernel Features > Kernel support for 32-bit EL0 > Fix up misaligned multi-word loads and stores in user space
# Device Drivers > Graphics support > Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) > Intel Xe Graphics (is disabled by default)
# Device Drivers > Graphics support > Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) > Intel Xe Graphics > Force probe xe for selected Intel hardware IDs > 56a0

The ID 56a0 matches my GPU from the list https://dgpu-docs.intel.com/devices/hardware-table.html

Then the boring compile stuff.

make -j$(nproc) Image.gz modules dtbs
make modules_install
# installing the generated files
cp arch/arm64/boot/dts/broadcom/*.dtb /boot/firmware/
cp arch/arm64/boot/dts/overlays/*.dtb* /boot/firmware/overlays/
cp arch/arm64/boot/dts/overlays/README /boot/firmware/overlays/
cp arch/arm64/boot/Image.gz /boot/firmware/kernel8-xe.img

# selecting the new compiled kernel
echo "kernel=kernel8-xe.img" | tee -a /boot/firmware/config.txt

Out of the box I get hit by outdated firmware files:
