Support for RTL9607C / RTL8198D Realtek SoC

Last edit date: Janurary 5th, 2026.
Quite a lot happened after September that i think makes it worthwhile to edit some of this original post.

Hello there,

I think it would be a good idea to have a general place for discussions on RTL9607C / RTL8198D SoC, routers (ONTs) based on this chip and their potential OpenWrt support.

As of now, i have a pull request pending to support loading initramfs image on these SoCs based machines. It is not much but at least it is a start.

This patch/commit adds a new subtarget RTL9607C/RTL8198D to realtek platform wit…h some initial support. I am a simple hobbyist and since it is my first time contributing to this project, i would appreciate all feedback and advice from you to fix any kind of mistakes here and whatnot. RTL9607C and RTL8198D both are identical dual core SoCs based on MIPS InterAptiv. RTL9607C is found in many ONTs with XPON capabilities while RTL8198D is found in many typical wireless routers. The most recent GPL source code, which is based linux 5.10.x version, contains all the necessary drivers for these SoCs and the Realtek SDK for it. I have uploaded it to my github: https://github.com/jameywine/GPL-for-GP3000. Surprisingly, it has a lot in common with RTL931X SoC. Most of the dtsi, config and makefile was copied from it. ~I had added a simple clk driver based on the existing clk driver from gpl source code~ (edit, it is now a simple dts node for fixed clock), chip info for this RTL9607C/RTL8198D in prom.c and patch to include them as a config option. Bootloader on these machines are based on Uboot 2020.01 with Bismarck Preloader and have tftp client capabilities which make it easy to experiment with. Rather interesting cause other Realtek SoCs have Realtek specific bootloader. At this current moment, only initramfs booting on rtl9607c and rtl8198d based machines is supported. Instructions to boot initramfs from bootloader: 1. Connect to UART on the board and power on the machine. 2. Press any key in the first 2 seconds to interrupt the boot. 3. Enable tftp server on your device from which you want to transfer firmware from, with an ip set to ipaddr env variable. 4. Connect the ethernet cable to the rightmost LAN port (LAN1 or LAN4). 5. Run the command "tftp initramfs-kernel.bin". 6. After it is loaded, type "bootm" to boot into initramfs.

Update Janurary 5th, 2026: i have also added rtl960x support to existing thermal driver, which enables the thermal sensor of the CPU, and I2C driver, which enables i2c communications with laser driver. Also, i have tested my rtl9607c based router with Linux 6.18 from this pull request and it appears to be functioning as normal.

Comment by jameywine - [WIP] realtek: add support for kernel 6.18

main ← jonasjelonek:realtek/6.18

Hi @jonasjelonek I have tested on my, not yet supported SoC, rtl9607c based …router and it boots just fine (just had to move all the things from [my pull request](https://github.com/openwrt/openwrt/pull/20064) to 6.18, thats it). I don't know if that helps here but testing is still testing. At least i know that i can easily rebase my pr to add 6.18 kernel support if this pr gets merged first. <details> <summary>Linux 6.18 boot log</summary> ```ini ## Booting kernel from Legacy Image at 83000000 ...

For flashing sysupgrade/factory images, i personally haven’t tested them because my unit is a primary modem (for which i also don’t have a firmware because vendor doesn’t provide any) and i don’t have any other RTL9607C / RTL8198D based routers so, if anyone could be willing to test, that would be really nice.

Looking at firmware from other routers, it is basically a tar archive file with uImage, rootfs and a fwu.sh files. From the looks of it, it is loading uImage and rootfs to ubi volumes ubi_k{num} and ubi_r{num} inside the ubi_device mtd partition. It is dual flash layout due to presence of ubi_k0, ubi_k1 and ubi_r0, ubi_r1, which is the same layout on across the whole RTL9607C platform. Some RTL8198D based devices seem to also share the same firmware structure.

Potentially could be used to switch between OpenWrt and vendor firmware?

Update Janurary 5th, 2026: The ECC driver got merged into mainline linux and back-ported into OpenWrt. This now gives the ability to attach ubi_device partition and do stuff with it.

There is a GPL source code available from which is based on Linix 5.10.x and have all the necessary drivers for RTL9607C, from usb, pci to ethernet, wifi and the whole Realtek SDK.

Update Janurary 5th, 2026: Included the list of essential drivers/components and links to them:

USB Driver: Link
PCI Driver: Link
GPIO Driver: Link
Ethernet/NIC Driver: Link
Wifi Drivers: Link
SoC Drivers: Link
GPON Driver: Link
Hardware Offloading Drivers: Link
OMCI Driver: Link
Bismarck Preloader Code: Link

I have already started work on USB and PCI part (based on the drivers from GPL source code) but haven’t tested them because i wanted to keep pull request as simple as it can be for reviews. Some present realtek drivers can be reused for RTL9607C, perhaps with minor tweaks in some cases.

Update Janurary 5th, 2026: While i did some work on USB and PCI drivers, they are in back-burner right now.

Any kind of help or feedback are welcome here

Oh if someone asks, i included RTL8198D in the title because its arch folder from gpl source code is a symlink to RTL9607C, ~~which could very much mean that they share a lot in common with each other but it needs testing to verify that.~~
Update Janurary 5th, 2026: Yes, that is now 100% verified

Comment by jameywine - realtek: add a new subtarget rtl9607c/rtl8198d with basic support

Forgot to remove the leftover PCI config stuff after trying out PCI driver, whic…h was resulting in build failure, but that should be fixed now. I will also use it as opportunity to share some of the bootlog snippets 1. Chip subtype readout works as intended, it correctly identified my RTL9607C-VB SoC `[ 0.000000] SoC Type: Realtek RTL9607C subtype 18 rev B (6831)` and also RTL8198D SoC which was tested by a different person. `[ 0.000000] SoC Type: Realtek RTL9607C subtype 1B rev B (6831)` 2.

Here is the /proc/cpuinfo from initramfs which surprisingly looks way more filled up compared to the /proc/cpuinfo from a vendor firmware. Don't know if that's a good thing or bad thing or is it due to linux version difference.

The plan is to make it work with XPON right ?

The Kernel comes up fine on my HW.

jameywine · September 19, 2025, 11:48am

Hopefully.. if all things work out but i wouldn't bet on it happening any time soon
And i would assume econet target is gonna be on the same boat as us too when it comes their XPON support.

In Realtek's case, the gpon driver seems be there. And more in dal/rtl9607c folder

But Ethernet support should come before that

Nice to see that, do you know if your RTL9607C is rev A or B? Would like to know if they both works cause i have seen some rtl9607c that run 900Mhz with 2 cores, while mine is 1150Mhz.
Bootlog would also be nice to see if you don't mind.

Let’s continue the development here in a fresh thread. I’ll be looking through the GPL code in your repo

jameywine · September 19, 2025, 5:00pm

Yes, i would hope it gets changed to generic "realtek" in the future to avoid confusion, if people from switch side wouldn't mind. My guess is that it got overlooked because it was very minor or something. Especially given rtl93xx stuff are also in there already.

As for the drivers, Here is what i got so far with rewriting pci driver, yet to test it out.

This is above is confusing as the target is already realtek with the following subtargets:

rtl838x
rtl839x
rtl930x
rtl931x

Would like to touch on the subject of permanent flashing and sysupgrade, which will need to be discussed sooner rather than later.

As it currently stands, the partition map, which is the same across other rtl9607c based machine (and seemingly rtl8198d according to this bootlog from this thread is this:

0x000000000000-0x0000000e0000 : "boot"
0x0000000e0000-0x000000100000 : "env"
0x000000100000-0x000000120000 : "env2"
0x000000120000-0x000000140000 : "static_conf"
0x000000140000-0x000007d80000 : "ubi_device"

boot partition is a u-boot binary
env is u-boot environment.
env2 is second u-boot environment?
static_conf seems to be some conf partition? It is filled with ffff for me.
ubi_device is a ubi device and it contains 5 ubi volumes.

From ubinfo -a command:

ubi_Config is mounted to var/config during linux boot and contains config files for OMCI, laser driver and config.xml, config-hs.xml files which seem to be central configs for the whole linux system. You can manipulate the system by changing parameters in config.xml and uploading the xml file through web ui.
ubi_k0 is a volume for the linux kernel.
ubi_r0 is a volume for the squashfs
ubi_k1 is the 2nd volume for the linux kernel.
ubi_r1 is the 2nd volume for the squashfs.

And it looks like you can choose which one to boot from by changing the uboot variable sw_commit to 1 or 0. But for some reason ubi_k1 and ubi_r1 are filled with ffff, at least in my case.

There is some leftover space at the end after ubi_device partition with the size of 0x280000 which is entirely filled with ffff.

This kind of dual boot layout inside one ubi device seems be a unique feature to this platform because other routers i looked at that have dual boot use 2 ubi devices instead (or 2 mtd partitions). Can't really put my hand on what would a proper sysupgrade or factory image would even look like so i would appreciate any help or insight on this matter.

mkverma97 · September 22, 2025, 3:15am

I have both 9607C-VA and 9607C-VB with me. I had tried on VB and that’s where it had come up. I will soon share with you the bootup logs from VB.

mkverma97 · September 22, 2025, 4:16am

For dual bank system, what happens is, as the device will be up and running with FW in one bank say “bank 0” (considering banks are bank 0 and bank 1), then the FW which is downloaded will be written into bank1 and committed in the bootloader env. Then on reboot, the device will come up with bank1 FW.

The FW usually consists of a kernel, rootfs, upgrade scripts, sometimes even bootloader. The k0/k1 is for the kernel and r0/r1 is for the rootfs of the two banks.

If you have any FW with you for the device that you are already using, you can untar/binwalk and check all its components.

BTW, here is the bootup logs from my VB HW.

Been a while since the last message (IRL is partially to blame) in this thread so i might add some progress news and what not..

Big kudos to @kenjiuno for verifying the theory i had for a while, RTL9607C and RTL8198D are indeed very much the same SoCs. This is what the bootlog prints out for RTL8198D based machine [ 0.000000] SoC Type: Realtek RTL9607C subtype 1B rev B (6831). The subtype, which is quite a recent addition to the pull request, is 1B does line up with the table, showing that it is RTL8198DE. The main difference is of course that RTL9607C is for XPON ONTs while RTL8198D is for general wireless routers.
I have tested the PCI driver i have written before (based on the pci driver from GPL code) for a couple days already, but it continues to now work at all. The boot process stops midway without any errors or indicators. The driver code is pretty much the same as the one i posted in the previous message. From what i have checked, this line of code is what is causing the boot stop (at least for PCIE0)? if((ioread32(p->hostcfg_base + 0x0728) & 0x1f) == 0x11)
I can't really put my head around why it could be doing it. Hey @undisputed-seraphim, did you have any luck with your pci driver loading on rtl8198c so far by any chance?
The pull request for Realtek ECC driver has been finally merged, so that allows us to make attach the ubi_device and potentially open the door for flashing the sysupgrade image? The build recipe for sysupgrade stuff is still an unknown element to me...
At this current moment https://svanheule.net/realtek/ is not available so... I plan to have a separate github repo/site for all RTL9607C registers and internals and what else could be documented but that will take some time because there is a lot of things.
It would also be nice to have a github repo that builds the initramfs images automatically for rtl9607c (just like https://github.com/cjdelisle/OpenWRT-EN751221-Builds) so that people don't have to spend time building it, which shouldn't be hard to do.

Hi yes my pci driver works, however I am missing the interrupt mappings so devices can be detected but they can not run properly. I am stuck at that problem because I do not know how interrupt mappings work, sadly

jameywine · October 13, 2025, 8:21pm

Oh, i see
is it something different from a pcibios_map_irq function or is it more related to interrupt-map property in the device tree? I assumed that interrupts = <GIC_SHARED 32 IRQ_TYPE_LEVEL_HIGH>; would be enough cause pci driver doesn't involve interrupts much. In that case, wouldn't something like this work? (from mt7621.dtsi, cause its the only one where its managed by GIC)

interrupt-map-mask = <0 0 0 0>;
interrupt-map = <0 0 0 0 &gic GIC_SHARED 24 IRQ_TYPE_LEVEL_HIGH>;

Otherwise, i have no clue.

...and also means something is wrong with my pci driver too if yours work. And also the fact that pci driver is run at late_initcall instead of arch_initcall but that shouldn't affect anything i think.

Hi!

Where could it be found?

AFAIK it's okay for one port to fail check after initialization, at least I saw this on reference software and everything worked fine

Hey, welcome to OpenWrt forum

I believe this is the pci driver in mention

Noted but i didn't do much pci drivers stuff since then because i just couldn't pinpoint the cause of the boot hang and there were a lot of variables in play.

For once, maybe my patch to make rtl9607c work with upstream gpio-realtek-otto driver was incomplete or something. In RTL9607C there is a register called IO_GPIO_EN at 0xbb000038 which seems to be controlling GPIO pins and IER register for "interrupt enable register for CPU0/1".

Maybe my rewritten pci driver has a flaw or i skipped over something that i thought was unimportant but was actually crucial, who knows.
It failing at if((ioread32(p->hostcfg_base + 0x0728) & 0x1f) == 0x11) just doesn't make sense when i know p->hostcfg_base is properly defined during probe so.. my take is that it is likely a GPIO issue which happens after the gpiod_set_raw_value, otherwise i don't know what could it be..

I will try and look at pci/gpio drivers again in the future when i have time.

While i am here, I went on and updated some portions of original post of this topic.
TLDR:

ECC PR has long been merged, so the old text is obsolete.
I have added thermal and i2c support for this SoC.
I included the list essential drivers and components with links to them to make them easier to find for anyone interested.

I've spent some time debugging PCIe driver. That's what has been changed:

fixed tmp = (p->port) ? RTL_ENABLE_PCIE0 : RTL_ENABLE_PCIE1;, what leaded to hangs
changed of_property_read_u8 to of_property_read_u32 for port property (I think it was only my problem with dts format - 0 was always returned, what also leaded to hangs)
removed all mb(), as ioread/write doesn't need it
changed ioport_resource addresses (still don't know how to handle it correct)

For now boot hangs after first read from PCI device config address - I believe that it is because of reset gpio wasn't set

What leads to another topic - GPIO. According to this scheme, otto driver should work (plus I corrected controllers addresses). But I still can't manage device's leds using /sys/class/gpio. Maybe because of strange GPIO base - 512:

root@OpenWrt:~# ls /sys/class/gpio/
export       gpiochip512  gpiochip544  gpiochip576  unexport

Anyway, everything I've got is here (head commit) - https://github.com/ProMix0/openwrt/tree/rtl9607c-dev
