not much to say if you don't have any logs, on VS seem to be working... what I can tell you now is that you can remove " video=eDP:d video=DP-1:d video=HDMI-A-1:d video=HDMI-A-2 :d' " and don't keep a monitor plugged in .

where exactly are you failing?

Hi,
if anyone is interested to fix the boot with vd-t enabled, you can use the following kernel parameters
iommu=soft iommu=pt intel_iommu=on -

Hi
Just installed 1.04b and DSM 6.22 (latest, it was automatically downloaded) on an Asrock J4105-ITX
Worked at first try, thanks!
The only doubt I have is that after enabling SSH, I checked
/dev/dri ->Folder does not exist
cat /usr/syno/etc/codec/activation.conf ->File does not exist.I have used the MAC and S/N of a real DS918 btw, but my NIC S/N does not match the one in the config.. maybe this could be the problem?
you had a previous install on the drive and you didn't format the disk, the boot arguments in dmesg shows DS918 SN?

SMB read/write speeds improved from 30-70 MB/s to 90-110 MB/s

J4205-ITX DS918+ Jun's Mod V1.04b
dd bs=1M count=1k if=/dev/zero of=/dev/null | md5sum d41d8cd98f00b204e9800998ecf8427e - 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 0.164326 s, 6.5 GB/s -
hi,
don't assume all issue are related, could be just a faulty plex install or upgrade, I prefer in between testing iterations to format the drive just to get a consistent behavior.

May I ask what Bios version you have on your J4205?
1.80, with specter and meltdown on, should I expect big difference in performance if I disable meltdown?

12 hours ago, pmchan said:So, if I understand well, Plex HW transcoding is working good when setting the bios like you did and kindly explained?
I can't get my Q1900-itx to boot headless, so I plugged in permanently an active hdmi to DP adapter and it doesn't cause reboot when transcoding like apollo lake. Did you managed to boot the J4205-itx headless or do you unplug the monitor cable after boot to get HW transcoding without instant crash?Both works for me, booting headless or unplug the monitor after you have everything set up.
I find it hard to recommend this board, generally I find it hard to get a consistent behavior out if it. currently I have gigabyte 1037u that is working 24/7 for 5 years no problem, this one I'm still testing.
on J4205 hw transcoding still buffering in Videostation but In Plex seem to work ok . I'm currently checking why transfer rates are inconsistent sometimes.
With all this said if you need hw transcoding or you try to get as close as possible to the real DS918, DS1019, DS619slim, apollo lake boards are your best bet. Maybe Gigabyte has a better implementation with GA-J3455N-D3H if you can find one.

I have quit working with Loader 1.04b/DS918+ because of the really annoying performance and swiched back to 1.03b/DS3615xs. Now my geekbench results are 1921 / 3013 compared to poor 956 / 1396 before. Also copy speed to usb ist twice as fast. The last plus for DS918+, the NVMe Cache, didn't work, because my Samsung PM981 was not recognized by DSM (and also not on my Pentium G4400 test system).
@x01015918 i have spend some time with different bios settings and found no way to check if cpu boost is working at all.
ok.. I will test myself if performance improve on ds3615,
I tested burst performance like this
echo "0" > /sys/devices/system/cpu/cpufreq/boost dd if=/dev/zero bs=1M count=1024 | md5sum echo "1" > /sys/devices/system/cpu/cpufreq/boost dd if=/dev/zero bs=1M count=1024 | md5sum -
nvm...

May be this /sys/module/i915/parameters will help you. I did it @TeleDDim
that is the point changing /sys/module/i915/parameters is not working by grub args, and the insmod i915.ko modeset=1 works only until reboot.
this one also is not working
root@DS918:/lib/modules# echo "1" > /sys/module/i915/parameters/modeset -ash: /sys/module/i915/parameters/modeset: Permission denied -
Hi,
I was trying to test couple module parameters for i915 but they are not picked up if set in the grub.cfg as extra_args.
I could do it this way but it's not persistent after reboot
cd /lib/modules rmmod i915 insmod i915.ko modeset=1Can anyone help me with a permanent solution?

if you keep digging on the forums a lot of people complain about the board and most have different heretic behavior, like this guy have even weirder issues on windows, somehow it explains why we notice different behavior with the same boot image or extra

Транскогдинг не работает с оригинальным загрузчиком судя по всему из-за наличия на плате J4205-ITX конвертера MCDP2800.
I will try and update the chip firmware this weekend.

Did you try start both apps (VS and Plex) at the same time? In my system VS stops buffering and works smoothly
no difference for me

try also and update i915 firmware, in my extra I added the latest ones.

mine is not rebooting, just buffering every 3-5 sec, I do always keep the display unplugged (that is causing me reboots but also in plex) my point is that if the drivers is loading fine in dmesg, hw trancoding is working in one of the apps the only different thing is the version of the codes VS is using.
-
VideoStation experience is bad for me also, but I don't use it. I don't think it's a matter of drivers anymore but codecs. VS is using their proprietary version of ffmpeg and in the older versions could sideload parts of 3rd party ffmpeg functions but no longer.

I can transcode 2 4k HEVC simultaneously with plex but VS is buffering on 1 1080p

Is it properly detecting your cpu?
Quotecat /proc/cpuinfo
you have boost disabled in bios, not sure how amd calls it.

what is the output for
dmidecode -t processor | grep Speedecho "1" | sudo tee /sys/devices/system/cpu/cpufreq/boost ?
hw transcoding fix v1.04b DS918+
in DSM 6.x

Maybe this can help...
