SSDT2 is properly there. I’ll then try defconfig, thank you for the test!
OK now I can confirm that cppc_cpufreq in defconfig works properly, that’s perfect, thanks! I’ll diff the configs to figure what makes the difference, but for now it looks like mainline is working fine for me.
Here’s from Debian (Linux debian 6.12.9+bpo-arm64 #1 SMP Debian 6.12.9-1~bpo12+1 (2025-01-19) aarch64 GNU/Linux)
Can’t get bsa.efi to log to file. I run Bsa.efi -v 1 -f bsa.out, a bunch of tests look to pass and then the screen goes corrupt, but nothing in the file on reboot. I’ll try again at some point
For BSA ACS it is better to connect serial console and log it’s output rather than trying to log into file.
ACS leaves system in a state where reboot is required.
I got BSA ACS (ACPI mode) results from one of board owners.
Looks quite nice, some issues present, part of them can be solved by firmware.
I suspect that whoever did firmware did not looked at BSA ACS or FWTS results.
Just FYI, I could bisect my configs this afternoon and finally found the option that is required for CPPC to work. The config requires CONFIG_ARM64_AMU_EXTN=y. It was disabled in my generic config, as the help text says that using it on non-compliant firmware can result in hangs at boot. Now CPPC seems OK on mainline with my portable config. I’ll retest later if kernels having this option still boot fine on RK3588. We’re getting close to something quite clean now.
Upstreaming starts:
yep, I noticed it yesterday 
Great news 
I have question regarding pcie slot, it was said that no bifurcation support at this time, is that hardware limitation or just no plans on software for that now?
Hardware limitation 
Is JTAG/SWD available on easy-access pin/header and is it unlocked/unlockable on the SoC? (Secure boot seems present, if so this might disable it).
That is a good thing, but that should be done in parallel with publishing source code for the current kernel.
It’s already on the schedule, next week we will publish the 6.1 kernel source code, EDK2 source code and the Debian image build scripts.
no source for the vendor 6.6 (ACPI) kernel? 
The UEFI GOP of the o6 does not work on some high-resolution, high-refresh-rate monitors (e.g., my display defaults to 2880×1800 @90Hz), resulting in a black screen, but it functions properly at 1080p resolution on my Rock5B UEFI.

total 6 modes (current pixel clock 50671, width 2880, height 1800)also cant get my ultrawide running with 5120x1440, changing Kernel parameters doesn’t fix it
In case that helps people who want to try mainline kernel:

sudo mount /dev/nvme0n1p1 /boot/efi
sudo apt -y install dracut build-essential bison flex libssl-dev firmware-linux firmware-linux-nonfree

sudo sed -i 's/default=.*/default="'"${NUM}"'"/;s/timeout=.*/timeout=10/' /boot/efi/GRUB/GRUB.CFG
The kernel config is not perfect; I’ve used defconfig and changed a bunch of drivers to be compiled in because initramfs-tools were slightly broken and did not include the NVMe module, for example. But I haven’t paid too much attention to removing unneeded drivers.
Vanilla kernel OOPS on boot if I plug USB-C ethernet adapter (I had it for debugging purposes) and hangs at boot if I have Radeon RX6400 installed, but boots just fine with rx550.
Also, for newer GPUs, more recent firmware might be required, so something like that would help:
git clone --depth 1 https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
cd linux-firmware
sudo apt -y install rdfind
sudo make install
sudo make dedup
It would be better though to
Mainline linux upstream status updated from mailing list:
https://lore.kernel.org/linux-arm-kernel/Z8AcFq9bDuW0oiD5@nchen-desktop/
This response from Peter already seems more reflected than anything I’ve seen in the last years from some other SoC manufacturers. I wonder how far along we’re gonna be in a year
If they don’t have to change the device tree format to accommodate the new chip’s power sequencing I expect this one to go along much faster than recent Rockchip stuff did. No waiting on RTC clock sequencing or having to wait over a year for a gpu driver this time around before adding video ports. Panfrost driver testing on some V12 Mali HW has already begun and the first merge requests for V11/V12 have started coming in.
At least I don’t understand the rationale of upstreaming DT support since the BIOS supports ACPI. It would be much simpler to simply skip DT and focus on stuff that will allow modern distros to boot out of the box. They’re just postponing decent support for no perceivable reason. Also, delaying the access to the kernel tree only makes the situation more complicated for them since nobody can help them.
For example at this point I’ve tested all I could reasonably test, provided feedback. Now I have this board running on my desk, I cannot even try to fix anything nor even hack the ACPI stuff since no access is given. That’s strange :-/
