Dual Gfx Card: Radeon HIS4670 + RX550.

[AlfredOne]

Hello,
I'm trying to get these two graphics cards to work together in the X1000.

-----------------------
Hardware Setup:
-----------------------
The cards are installed as follows:

• 1st PCI-E slot: Radeon HIS4670 (RV730 chipset, card name "Radeon RV730")

• 2nd PCI-E slot: Radeon RX550 (POLARIS12 chipset, card name "Radeon RX Polaris12")

Note : To prevent the X1000 from waiting endlessly for the initialization of the RX550 when CFE boots, i had to disconnect the GPIOLV10 jumper.


------------------------
Software Setup A
------------------------
In the DEVS:Monitors there are 3 files:

• "Radeon RV730"

• "Radeon RX Polaris12"

• "PCIGraphics"

The kickstart modules loaded are the following:

• RadeonRX.chip (v2.12)

• RadeonHD.chip (v3.7)

------------------------
Software Setup B
------------------------
In the DEVS:Monitors there is 1 file:

• "Radeon RV730"

The kickstart modules loaded are the following:

• RadeonHD.chip (v3.7)

-----------------------
Result
-----------------------
What I get is a crash as soon as the kickstart modules are loaded.
With Setup A, the crash occurs with the AmigaOS4.1 logo on the 1st graphic card.
With Setup B, the crash occurs as soon as the AmigaOS4.1 logo disappears and the empty workbench screen appears.
Serial logs attached.


I invoke Hans' help!

I never tested such configuration.

In 2020 I tested this X1000 configuration:
Slot 1 (PCIe x16/x8): HD7970
Slot 2 (PCIe x8): HD6670
All worked without problems under AmigaOS. I am not remeber RadeonHD.chip version, but it was the one actual from year 2020.

I had ( according to document https://amigaone.files.wordpress.com/20 ... _X1000.pdf ) three monitors in Devs:monitors
- RadeonHD7970
- RadeonHD6670
- PCIGraphics
It is necessery to set Icon tooltypes BOARDNAME and CMPLENGHT. CMPLENGHT should be long enough to see diference in Boardnames.
I.e. in my setup CMPLENGHT=8 is wrong, becouse first 8 character of both monitor names are "RadeonHD", and is the same for both cards.
If CMPLENGHT is 9 or more, it works fine, becouse compared string are differs ( RadeonHD7 vs RadeonHD6 vs PCIGraphi).
And one thing - I have the same results both with and without PCIGraphics in Devs:Monitors.

As I know, dual monitor feature is very old, from the times when RadeonHD cards has only 2D support, and for hw 3D you need something like Radeon9200 in PCI port.
I am not sure, if this feature still developed/maintained or not. At least first RadeonHD.chip v5 not worked properly with dual monitor setup.

You can also ask about X1000 dualmonitor on amigans.net. Hans is there and can give you exact answers.

Up to now I have used the following two cards:
Slot 1: Radeon R9 280X (HD
Slot 2: Radeon HIS4670
Both cards works with RadeonHD drivers V3.7.

Now it would have been useful for me to use a Radeon RX550 together with one of the two RadeonHDs but there appears to be some incompatibility between the two RadeonRX and RadeonHD drivers preventing booting.
So I was wondering if anyone had managed to use a RadeonRX and a RadeonHD in dual configuration at the same time.

One more thing:
try to swap the RX and HD card positions,
When I tested configuration primary RadeonHD gfx, and PCIe switch + secondary RadeonHD gfx + NVMe it worked with switch in fist slot, and not works in second.
