MPC7500:
What was your previous step?

MauryG5:
So I'll give you a summary, after doing those steps where I was stuck, I went to the part where you must first download and then apply the kernel patches.

[user @ bb git] $ cd fedora /
[user @ bb fedora] $ wget https://gitlab.freedesktop.org/drm/amd/uploads/f8c299fc4fd373a8cbc380f348204b61/0001-amdgpu-Prepare-DCN-floating-point-macros-for-generic.patch
[user @ bb fedora] $ wget https://gitlab.freedesktop.org/drm/amd/uploads/7d194992837c8706ca5966b682d5680b/0002-amdgpu-Enable-initial-DCN-support-on-POWER.patch
[user @ bb fedora] $ wget https://gitlab.freedesktop.org/drm/amd/uploads/86353afdb43409add84005cef8c5abc0/0003-amdgpu-Wrap-FPU-dependent-functions-in-dc20.patch
[user @ bb fedora] $ git am * .patch

Up to this point no problem, he did everything according to the guide.
Then he tells me to do this command:
[user @ bb fedora] $ sed -i 's / .num_dsc = 5, // g' drivers / gpu / drm / amd / display / dc / dcn20 / dcn20_resource.c
Without this the system has not returned any error to me and so I went ahead in the procedure and I got to the point where it tells me to configure the kernel and to do it you must enter that famous command that I posted and that does not work ... And I got so stuck ... Last step is the command line that you see immediately above or the one where you talk about drivers and diplay ...

MPC7500:
Original line from the wiki:

--- Code: ---sed -i 's/.num_dsc = 5,//g' drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c
--- End code ---

Your line:

--- Code: ---sed -i 's / .num_dsc = 5, // g' drivers / gpu / drm / amd / display / dc / dcn20 / dcn20_resource.c
--- End code ---

Compare. You should really copy&spate the lines

MauryG5:
it seems strange to me because I copied exactly without touching anything, the line that comes out in my previous message has different spaces but I don't remember that there were in the original that I copied ... very strange ... I'll check this evening and I see if it is actually how it comes out in my message but in any case it has not even returned errors like too many arguments in the line ... I honestly don't understand ... ???

MauryG5:


MPC I checked the command line you posted, if you notice the original of the guide, you will notice that it is exactly the one I posted, if I do copy and paste, obviously I don't go to think that there are more spaces otherwise I would go to intervene. Also while in the line that you had previously pointed out to me, it gave me error of excessive arguments, in this case it takes the command and makes you continue so I could not imagine ... In any case this evening I try in the mode you posted and then I go to redo the command that gives me the error of which I spoke yesterday, let's see if correcting the previous line, I can go on. But at this point it is necessary to report to Meclort because even when you do the NVRAM update in petit boot, the line which is then reported as a guide also has too much space and consequently the system returns an error. Too much space is found after 0 at the end of the line ...

# nvram -p ibm, skiboot --update-config fast-reset = 0

 this is the line with the extra space at the end that makes you get out of error, on this I realized and I corrected it, on the others I made a copy paste and I didn't realize it
