How it gets the rom is probably the same as this shell script using the pci method listed on that github link in the last comment. # To read ROM you first need to write `1` to it, then read it, and then write # `0` to it as described in the documentation. The reason is that the content # is not provided by default, by writing `1` to it you are telling the driver # to make it accessible. CARD_ID=0 CARD_ROM="/sys/class/drm/card${CARD_ID}/device/rom" FILE_ROM="amdgpu-rom.bin" echo 1 > $CARD_ROM cat $CARD_ROM > $FILE_ROM echo 0 > $CARD_ROM echo "Saved as ${FILE_ROM}" -- output: cat: /sys/class/drm/card0/device/rom: Input/output error [Not] Saved as amdgpu-rom.bin Is there any other user-space accessible methods to extract / write the rom in Linux? Now only focusing on comparing the pp table to other roms not modifying it. Maybe the powerplay is an atom-bios issue perhaps. If it's still broken in this 4.16-rc1 version I'm trying out now I'll open a ticket. For your reference this is the ticket that claims powerplay dpm is fixed in newer kernels / dc=1 in 4.15. <a class="bz_bug_link bz_status_RESOLVED bz_closed" title="RESOLVED FIXED - DMESG: [powerplay] Can't find requested voltage id in vdd_dep_on_sclk table!" href="show_bug.cgi?id=100443#c37">https://bugs.freedesktop.org/show_bug.cgi?id=100443#c37</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
