Hi Yusuf,

That is an expected result. 256MB is not enough for
the VRAM BAR and the doorbell BAR to fit into. But you
can still use VGA emulation that way if I'm not
completely mistaken.
Hmm, then what procedure should I follow to take a VGA
output. It seems Graphic Card does not have a VGA output.
And isn't there any way to use this GPU with a 256MB
buffered PCIe?
Most likely not. There is support for resizing the VRAM BAR, but
usually you can only make it larger and not smaller.
Please give me the output of "sudo setpci -s 0001:01:00.0 ECAP15+4.l
ECAP15+8.l" if you want to double check that.
Then I canged 256 MB to 4GB in
.dtsi and U-boot conf file.
How did you do this? Is your memory layout consistent?
See when you just changed one end address you might need
to adjust other addresses as well.
Regards,
Christian.
It's not consistent I seems. At first I changed .dtsi
like it's consistent. I only changed PCIe1 Device Memory and
I/O range. It gave same error. Then I also changed PCIe2 and
PCIe3 devices starting adress according to PCIe1 device end
adress in .dtsi. I am not sure I made this correctly or not
but it gave same result again. This is why I asked "If it
is, is there any sample PCIe configuration for E9171?".
Well you rather need to ask if anybody has sample PCIe configuration
for GPUs in general. That problem is not really E9171 related. You
might want to ask NXP for that maybe.
This is a code piece from my
T104xRDB.h file which is contain PCIe configuration
variables for U-boot. I made changes like it's not
consistent. RAM size is 8 GB.
Sorry, no idea if that is correct or not. You need to ask NXP for
help with that.
Regards,
Christian.

My embedded board is freezing when
I put E9171 on PCIe. What is the
meaning of Unrecoverable Machine Check
error about GPU?
Well see the explanation on Wikipedia for
example: https://en.wikipedia.org/wiki/Machine-check_exception
In general it means you have messed up
something in your hardware configuration.
Could PCIe settings in .dts file
cause this problem?
Possible, but rather unlikely. My best guess
is that it is some problem with the power
supply.
If it is, is there any sample PCIe
configuration for E9171?
The E9171 is just a PCIe device, so the dtsi
is actually rather uninteresting. What we
really need is a full dmesg and maybe lspci
output would help as well.

Christian.
Hi Christian,
At first, I am using NXP T1042D4RDB-64B
which has 256 MB PCIe buffer according to its.
PCIe memory range was arranged to 256 MB in
.dts file and in U-boot configuration file.
Driver was giving error with exit code -12
(OUT_OF_MEMORY). But I was able to reach the
linux console.
[ 5.512922] [drm] amdgpu kernel
modesetting enabled.
[ 5.517065] [drm] initializing kernel

[ 5.529296] amdgpu: probe of 0001:01:00.0
failed with error -12
Then I canged 256 MB to 4GB in .dtsi and U-boot
conf file. I also changed 64KB I/O size to 1MB .
When I do this, I wasn't able to reach the linux
console because board was freezing. But driver was
successfull at this time. I already mentioned
successfull driver console logs up.
this is lspci -v when GPU is plugged and
Memory size is 256 MB.
