deeveedee Posted July 18 Share Posted July 18 (edited) After disabling the DMAR table mods in my hack's EFI, I am seeing consistently (albeit slightly) improved GeekBench 6 Metal benchmarks (Radeon RX 560x). Benchmarks showing this improvement are repeatable. Is this what others would have expected? Note that my hack does not require the DMAR table modification or OC's DisableIoMapper quirk when VT-d is enabled in BIOS. My original and modified DMAR tables are attached. My current EFI is also attached. My hack's config is as follows: HP EliteDesk 800 G4 Mini (Intel Q370 Chipset, Intel i5-8600 CPU, 32GB DDR4-2666 RAM) Radeon RX 560x 4GB Mobile dGPU non-headless iGPU FrameBuffer (0x3e920000) SMBIOS macMini8,1 EDIT: Thank you @ird for inspecting the attached files and notifiying me about the incorrect original DMAR table that I had posted. Attached is the correct original DMAR table (which now includes the Reserved XHCI region).

deeveedee Posted July 19 Share Posted July 19 (edited) Thanks to @ird for reviewing my previous post and informing me that I had attached the wrong original-DMAR table. My previous post now attaches the correct original-DMAR table (which includes the Reserved XHCI Region at PCI Path 14,00 as it should). @ird Asked a question for which I don't know the answer: What is at PCI Path 16,07 (also a Reserved Region in my original-DMAR table that I attached in my previous post)? Reserved Memory Region, PCI Path 16,07 Spoiler If I inspect IOReg dump, I see IMEI @16. Edited July 19 by deeveedee Link to comment Share on other sites More sharing options...

deeveedee Posted July 19 Share Posted July 19 (edited) @Mieze Thank you for the quick response! Yes, I know what IMEI is. I was simply stating that my original/unpatched DMAR table includes Reserved Memory Region for PCI Path 16,07 and the closest I could find in IOReg Dump was IMEI @16. Is the Reserved Memory PCI Path 16,07 for IMEI? Edited July 19 by deeveedee Link to comment Share on other sites More sharing options...

I dunno how you should do this with OC. 1 Link to comment Share on other sites More sharing options...
deeveedee Posted July 20 Share Posted July 20 (edited) Based on what has been discussed in this thread so far, is it safe to say that this Dortania documentation (which states that all Reserved Regions should be dropped from the DMAR table) is incorrect? The "evidence" we have so far is that the DMAR table in a real MacMini8,1 includes a Reserved Region for iGPU @02,00 and Mieze's concerns here that dropping Reserved Regions from DMAR may have unintended consequences. At a minimum, maybe the Dortania docs need to be revised to suggest that only conflicting Reserved Regions (e.g., XHCI @14,00) should be dropped from DMAR? EDIT: If that is the case and if I needed to patch DMAR for my hack, the original and modified DMAR tables for my hack are as attached. EDIT: See Slice's conclusion here after reviewing my posted MacMini8,1 DMAR.
