makk Posted October 3, 2021 Share Posted October 3, 2021 After reading this post which lead to this page on link below, I'm wondering if this HP needs Stolenmen, fbmem? https://www.firewolf.science/2015/04/guide-intel-hd-graphics-5500-on-os-x-yosemite-10-10-3/ Which then gave me the Framebuffers I was looking for! Thank you Herve'! Love it! https://www.firewolf.science/2015/04/framebuffer-data-extracted-from-appleintelbdwgraphicsframebuffer-binary/ Work in progress as they say, never enough work done. I basically followed instructions based on what others have offered as 'good'. But after reviewing the Intel HD 5500 Frambuffer, VRAM, Memory FAQ, I am confused. Having first off, a Broadwell-U CPU 5200U and HD5500U Laptop series on HP Probook 450 G2 Should I have stolen memory configure? I can set in BIOS the memory for pre allocated DVMT above the recommended 32Mb to 64 96 or even 128mb according to the Firewolf. But what will this gain? Better graphics performance? How much if any to little significance or a great deal more significance? SETTINGS: BIO: 32MB for the Pre-allocated or Dedicated Memory for VRAM? Graphics memory config.plist ig-platform = 1626 as recommended by Whatevergreen page (testing 1616 with new framebuffer) Link to comment https://www.insanelymac.com/forum/topic/349133-question-and-desire-to-understand-stolemem-and-fbmem-inspired-by-last-tech-faq/ Share on other sites More sharing options...
makk Posted October 3, 2021 Author Share Posted October 3, 2021 Tested with 1616 for ig-platform > working Set the Dedicated Memory in BIOS to 128MB Disabled stolenmem, fbmem for the time being to see what happens >> testing with this off, I still have PNLF working.

Good idea too! 1 hour ago, Hervé said: Ha yes, I had missed that the Technical FAQ section may not allow mere mortals to post replies; this to keep the original topics intact and free from pollution I guess. See the original thread of 2012 pinned at the top of that section: https://www.insanelymac.com/forum/topic/283688-faq-start-here/ With regards to the questions raised above by the OP: -> answers are in the FAQ topic. -> No graphics performance to be gained, no. As stated in the FAQ topic, you may be able to obtain 4K output @60Hz if you set DVMT pre-allocated memory high enough. That's about it. Thanks, very good.

deeveedee Posted October 4, 2021 Share Posted October 4, 2021 (edited) @Hervé Your FAQ is incredibly well written. Thank you. I posted my observation (now the beginning of your FAQ) because I was experiencing com.apple.driver.AppleIntelKBLGraphics kernel panics as I stated here. It seems from your explanation that setting framebuffer-stolenmem=19MB and framebuffer-fbmem=9MB should be universally "safe" values, yet I can reliably and predictably experience com.apple.driver.AppleIntelKBLGraphics kernel panics when my framebuffer-stolenmem and framebuffer-fbmem are constrained in this way. The circumstances resulting in the kernel panic are a combination of streaming video in firefox and Tunnelblick OpenVPN with remote desktop. Note that I honed in on the culprits by first increasing the values of framebuffer-stolenmem and framebuffer-fbmem to 39MB and 21MB respectively and then by eliminating them completely from my OC 0.7.3 config.plist. Any idea why setting framebuffer-stolenmem=19MB and framebuffer-fbmem=9MB would result in com.apple.driver.AppleIntelKBLGraphics kernel panics on my Kabylake R rig (HP Envy x360 15 / HackBookPro15,2 (i5-8250U / UHD620))?

deeveedee Posted October 4, 2021 Share Posted October 4, 2021 (edited) 47 minutes ago, Hervé said: I don't know which KBL framebuffer layout you used for your Kaby Lake R UHD620 iGPU, possibly 0x59160009 or 0x591B0000 with iGPU fake id 0x5916, the iGPU of your i5-8250U carrying native unsupported id 0x5917. framebuffer 0x591B0000 with iGPU fake id 0x5916 47 minutes ago, Hervé said: suffice to say that the patched values were obviously just too small for the apps graphics requirements. I really could not say more. Given that the above 2 x actions you took caused no issue to boot your Hack, one can conclude that your system's DVMT pre-allocated memory must be set to, at least, 64MB; certainly not 32MB. Agreed. 47 minutes ago, Hervé said: As stated in the FAQ topic, the golden rule is the one to observe and it's recommended to try and identify the PC's default DVMT pre-allocated memory. I don't have Windows installed on my rig. I'm familiar with Firewolf's technique for determining pre-allocated DVMT in Windows. Do you know if there is a way to view DVMT pre-allocated memory in macOS? Note that my rig is a laptop that does not expose any DVMT configuration in BIOS. Thank you.

makk Posted October 5, 2021 Author Share Posted October 5, 2021 DVMT works in this laptop with higer settings when using HDMI. Had to lower the Stolenmen and fbmem then raise from 64 to 128. Opencore could not get HDMI Audio. Tried several combinations. In Clover simplified and works perfectly. I found Rehabman's several methods here and there for framebuffers. Finally found a simple one that works well. Lower the Framebuffer ones a bit and raise the DVMT. Then it works here. So Back to Clover and it runs faster now.

Guest 5T33Z0 Posted October 5, 2021 Share Posted October 5, 2021 I think the right move would have been to use the Dortania Bug Tracker to report/address the issue and discuss is with devs and authors of the guide directly.

I'm suspicious about "runs faster now" but the fact that you have no problems with CLOVER indicates that you're fortunate to have the alternative. Believe it or not, there were calls around this time in the CLOVER Discussion thread for Slice to abandon CLOVER and join forces with the OC team. Not that there was ever a chance that he would ever abandon CLOVER, but think about how crazy that was! Competition is good and the two bootloaders are a good thing.

makk Posted October 6, 2021 Author Share Posted October 6, 2021 With Fake ID's whatever works for your RIG. I've used Intel Desktop settings, Less than what this machine's specs for MacModels and well it's the options that you don't get in the presupposed mac model recommended to you in some post. I've used MacAir 7,2, MacBookPro 12,1, MacBookPro 15,1 each model as you know gives different options and configurations,, and other things, or not. Sometimes less than, and tradeoffs. 2 cores 4 threads. Ran 8 core 16 threads model and you get more goodies. Slice has much experience. He can tell you probably everything.
