is the worlds the most interesting use case I think. I can't increase
MMIO size because U-boot freezes. I can't decrease it to 256 MB again
because driver does not accept :D. I am just wondering, does modern gaming
motherboards have more than 4GB PCIe buffer for this job ? :D

Hello,
I have simple question. I want to use e9171 with my embedded t1042d4rdb-64b
board. Does linux kernel provide a driver for e9171? More specific, does
'amdgpu'(https://github.com/torvalds/linux/tree/master/drivers/gpu/drm/amd)
provides driver for e9171 ?
Best regards
ome sample PCIe
configuration for GPUs.
Thank you for your interest Christian.
Regards .

My embedded board is freezing when I put E9171 on PCIe. What is the meaning
of Unrecoverable Machine Check error about GPU?
Could PCIe settings in .dts file cause this problem? If it is, is there any
sample PCIe configuration for E9171? I attached my dts file.
System is working fine when GPU is
4_IO_BUS 0x
#define CONFIG_SYS_PCIE4_IO_PHYS *0xff812ull /* Did same things for IO *
#define CONFIG_SYS_PCIE4_IO_SIZE 0x00010000 /* 64k */
#endif

Hello AMD team;
I have E 9171 GPU and want to use it on a embedded system which has limited
MMIO space on PCIe bus (MAX 512 MB).
I received feedbacks that I can only use VGA emulation with this memory
space. I was unable to get 'amdgpu' driver working with Xorg due to I had
many errors(firmwares

Hello,
Still can't find a solution about this. Anyone can help me about this ?

I am having this error with kernel version 4.19 amdgpu driver for a
polaris12 based GPU. What could be the problem? Any suggestions? Thanks.
*Full dmesg:*

Hello,
First you could check if the binary ‘polaris12_smc.bin’ is in your system:
> /lib/firmware/../amdgpu/
>
'polaris12_smc.bin' exists in my /lib/firmware/amdgpu folder. There are
also 18 other binaries which starts with 'polaris12_'.
If it’s there, then does this happen after a warm reset?

Hello, I just compiled my 4.19 kernel with amdgpu driver (amdgpu as
builtin). The driver is giving me -2 error because of polaris12_mc.bin did
not found. I couldn't find that file anywhere. How can i get
polaris12_mc.bin and where should I place it ?
*Dmesg:*

Hello Alex,
Is this firmware differs on kernel version ? I am using linux kernel for
embedded device. If not, can I use the ones I found with google ?
Thanks.
