Develop and refine SA3600(broadwellnk) and SA6400(epyc7002) thread

[rok1]

I got mine working finally by turning off my internet during the install process. I now have 7.1.1-U5 working with HW i915 transcoding on an i7-10700.

 

I used jim3ma's loader

[Peter Suh]

With the help of wjz304, SA6400 7.2-64561 can be installed normally in M SHELL for TCRP.
As he advised, there was a problem somewhere in my EPYC7002 KVER 5 module.
It is not yet clear which part is the problem.
The final version of the ARPL module of wjz304, which has 70 modules, was also used for M SHELL.

FRIEND can keep the loader bus type as USB
Bare metal or VM (Proxmox, VMWARE ESXi) etc. have been verified.
Only 7.2 has been verified and 7.1 is still in testing.

thank you @wjz304

Thanks 7.2 seems to be working , 

7.1 seems to have an issue with e1000e (loses network connection) , not tried in Esxi yet .

Tried 7.1 in Esxi , it fails at around 58% possibly corrupt when installing pat file.

The kernel of SA6400 7.1 has many compatible issues with modules like mpt3sas. We should not use SA6400 with 7.1 any more.

Yeah I'd prefer not to , but it was the only way I was going to get hardware transcoding on the 11th Gen CPU I have, as there are the i915 and other modules backported by jim3ma . 

 

[scoobdriver]

For a workaround , I have created a small Photon OS VM in Esxi purely to run plex in docker , with quick sync HW transcoding , mapping media from a Xpenology VM . 

 

Hopefully with time some experts will discover a way of backporting i915 drivers for 11th gen and onward intel CPU's /iGPU so I can consolidate

 

Appreciate everyone's time , advise , and expertise .

I run SA6400 with jim's loader in PVE just fine.

However, when switching to Baremetal, I noticed two problems:

1. machine cannot start with num_netif > 4.

2. NVMe SSD is not recognized.

I installed 4 NVMe SSDs on a ASM2824 switch board. That makes the PCI path of it very long:

```

        nvme_slot@1 {
                pcie_root = "00:01.0,00.0,00.0,00.0";
                port_type = "ssdcache";
        };

        nvme_slot@2 {
                pcie_root = "00:01.0,00.0,04.0,00.0";
                port_type = "ssdcache";
        };

        nvme_slot@3 {
                pcie_root = "00:01.0,00.0,08.0,00.0";
                port_type = "ssdcache";
        };

        nvme_slot@4 {
                pcie_root = "00:01.0,00.0,0c.0,00.0";
                port_type = "ssdcache";
        };

```

And after painful search on the forum and then scroll through /var/log/message, I found that synology tries to find information about "FS2422N" in /run/adapter_cards.conf and it's labeled not supported on SA6400. I edit /usr/syno/etc/adapter_cards.conf and /usr/syno/etc.defaults/adapter_cards.conf.

```

[FX2422N_sup_nic]
[FX2422N_sup_nvme]
FS6600N=yes
SA6400=yes
[FX2422N_sup_sata]

```

Then the SSDs shows up.

 

I am doubting FX2422N is a new NVMe expansion chassis to be revealed. I don't really understand the reason but now it works, FYI.

 

And also I build kvm-intel.ko for VMM and tcp_bbr.ko for better internet transfer.

kvm-intel.ko tcp_bbr.ko

Hi, I encountered some issues using SA6400-7.1.1 migration. Currently, I have resolved the issue of kernel and GCC mutation environment, but the effect is not good. Do you have the bootloader for SA6400-7.2-64561? I want to test and learn.

[Orphée]

Hello,

 

If someone is interested, I built the WireGuard SPK for Epyc7002 DSM 7.2

 

Original souces and instructions here : https://www.blackvoid.club/wireguard-spk-for-your-synology-nas/

NOTE: If you are on DSM 7.2 be sure to reboot the NAS before running the startup script!

Next, jump back to the SSH prompt as root and run the following command to start the package:

Hello all,

 

I've read through every post and like many others am trying to get transcoding back on 11th Gen Intel baremetal. Previously had QSV working just fine on DS918 with ARPL but upgraded to more cores and may have jumped too quickly into DS3622xs (as it doesn't support QSV). 

 

Is SA6400 the way to go, if so, which version? Currently on ARPL DS3622xs 7.2-64570-3.

 

Thanks in advance.

[necro88]

Disregard... ended up rolling back to the 10th Gen and DS918+ loader. All is good now. Why fix what isn't broke 

[killseeker]

Sorry post removed.

Edited August 31, 2023 by killseeker

[Orphée]

@killseeker I understand you search for help, but the current topic is not related at all with DS918+ and QSV.

 

You should create a help thread or ask in more generic loader topic (M-shell, or TRCP, etc...)

[Peter Suh]

@jimmmmm

 

I tried applying this new module you added for lkm5 to lkm4.

 

https://github.com/XPEnology-Community/redpill-lkm5/commit/d7e0766776d4a9a3d62768f493d9d00581546635

 

 

An issue where the disk serial, which is part of S.M.A.R.T information, cannot be displayed when using HBA in DS918+ (Apollo Lake) has been resolved.

Thank you so much for adding such a great feature.

 

I have one question or additional request.
The SA6400 is a Device-Tree based model, so is this a function that HBA can use?

If this were possible,
I hope that HBA will also be activated in existing Device-Tree based platforms such as lkm4, Gemini Lake, v1000, and r1000.
Is it possible?

 

 

and,
I tested the HBA and SA6400 on bare metal, and it doesn't seem to work.
I checked in Junior with the command below, but the disk is not visible.

ll /sys/block

Actually, I don't know if the mpt3sas module was loaded properly.

 

When using lkm5 in the past, modules could be loaded.
The disk was also confirmed in the list.

 

However, there was an error message saying that hba could not be used.
Have things changed?

@wjz304, does your loader support hw transcoding for SA6400 ? Why is there no i915.ko in modules for SA6400?

You were running a custom built version with backported i915 drivers from Chinese 7.1 arpl link.

The default loader (and original SA6400) does not have this backported i915 driver.

So unless driver is backported again for 7.2, you won't have it on SA6400.

Oh, now i got it why.. So we need new .pat file...

SA6400 is an amd model and does not include an intel core graphics card. Jim developed 10-13 generation intel core graphics cards for sa6400.  And it is still being optimized, arpl-i18n will not integrate them without the author's permission. You can ask jim for details.

[Ardentwheel]

BBR can cooperated with Queuing Controlle like Fq or Cake.

 

Incase someone need it, there is Fq/Fq_Codel/Fq_Codel/Fq_Pie/Cake models

我在 PVE 中用 jim 的加载器运行 SA6400 就很好了。

然而，当切换到 Baremetal 时，我注意到两个问题：

1. num_netif > 4 时机器无法启动。

2. 无法识别NVMe SSD。

我在 ASM2824 交换板上安装了 4 个 NVMe SSD。这使得它的 PCI 路径很长：

````

        nvme_slot@1 {
                pcie_root = "00:01.0,00.0,00.0,00.0";
                port_type = “ssdcache”;
        };

        nvme_slot@2 {
                pcie_root = "00:01.0,00.0,04.0,00.0";
                port_type = “ssdcache”;
        };

        nvme_slot@3 {
                pcie_root = "00:01.0,00.0,08.0,00.0";
                port_type = “ssdcache”;
        };

        nvme_slot@4 {
                pcie_root = "00:01.0,00.0,0c.0,00.0";
                port_type = “ssdcache”;
        };

````

经过在论坛上痛苦的搜索，然后滚动浏览 /var/log/message，我发现 Synology 试图在 /run/adapter_cards.conf 中查找有关“FS2422N”的信息，并且标记为 SA6400 不支持。我编辑/usr/syno/etc/adapter_cards.conf 和/usr/syno/etc.defaults/adapter_cards.conf。

````

[FX2422N_sup_nic]
[FX2422N_sup_nvme]
FS6600N=是
SA6400=是
[FX2422N_sup_sata]

````

然后 SSD 就会出现。

 

我怀疑FX2422N是即将发布的新NVMe扩展机箱。我不太明白原因，但现在它起作用了，仅供参考。

 

我还为 VMM 构建了 kvm-intel.ko ，并为更好的互联网传输构建了 tcp_bbr.ko 。

kvm-intel.ko 5.26MB · 8 次下载 tcp_bbr.ko 544.45 KB · 3次下载

now I have successfully compile the i915 module, keypoint is to clean befor every rebuild and build under modules root directory.

make M=drivers/gpu/drm/ CONFIG_DRM_I915=m clean 
make M=drivers/gpu/drm/ CONFIG_DRM_I915=m modules

 

but now i'm faceing another issue, that is i915.ko modules dependency.

when i build i915 modules, it comes along with drm.ko drm_kms_helper.ko drm_panel_orientation_quirks.ko

I have try to insmod it, but shows error,is it have dependence modules i'm not build?

 

sudo insmod /lib/modules/i915.ko

It seems missing DMA & HDMI moudels, it's any way to build DMA as a kernel moudels?

now I have successfully compile the i915 module, keypoint is to clean befor every rebuild and build under modules root directory.

make M=drivers/gpu/drm/ CONFIG_DRM_I915=m clean 
make M=drivers/gpu/drm/ CONFIG_DRM_I915=m modules

 

but now i'm faceing another issue, that is i915.ko modules dependency.

when i build i915 modules, it comes along with drm.ko drm_kms_helper.ko drm_panel_orientation_quirks.ko

I have try to insmod it, but shows error,is it have dependence modules i'm not build?

 

sudo insmod /lib/modules/i915.ko

 

sudo insmod /lib/modules/drm.ko

 

insmod /lib/modules/drm_kms_helper.ko

I'm wondering why you are trying to run hardware encoding on the SA6400 model - after all, there are other models in which this works.
I would like to launch the SA6400 model to use more HDDs.
Now there is still an unresolved problem (maybe, of course, I’m behind and it’s solved) - if I create a model with 22 or more HDDs, but less than 21 HDDs are physically installed, when a USB drive or flash is connected, it is recognized as internal SATA.
I encountered this problem on DS3622 and RS4021.
If you can run SA6400 on Supermicro X11SPL-F + Gold 6138 it would be great. I have a lot of 500Gb HDDs and 2x LSI9201-16i for testing

In the case of SA6400, both rr and tcrp module loading methods do not directly inject modules using insmod or modprobe (dependency consideration).

As shown in the script below, copy all modules to /lib/modules and prepare them.

Regenerate dependencies with the command below.
Of course, if modules that depend on i915 are not properly prepared, this command may also send an error message.

depmod -a

Instead of directly injecting modules, we use “eudev”, designed and developed by ARPL’s Fabio.

And, although it may be a waste of your effort, @MoetaYuko has already completed a stable i915 module to enable transcoding on SA6400, as shown below.

This i915 module has already been applied to rr and tcrp-mshell.

However, the Intel CPU generations for which transcoding has been confirmed to operate are
These are the 4th, 11th, 12th, and 13th generations.

For other generations, the /dev/dri directory is checked and whether the i915 module is loaded is checked, but it does not work.
I am still finding out what more detailed adjustments are needed.
