MaLd0n Posted January 10, 2018 Share Posted January 10, 2018 Hi, There is some guide to know what is the best slide value for the osxaptiofix2drv. http://www.insanelymac.com/forum/topic/284656-clover-general-discussion/page-806?do=findComment&comment=2563456 Link to comment https://www.insanelymac.com/forum/topic/284656-clover-general-discussion/page/644/#findComment-2565838 Share on other sites More sharing options...
pico joe Posted January 10, 2018 Share Posted January 10, 2018 in my case if I use osxaptiofix2drv with slide=0 .. show does print work without slide=0 .. boot normal and can reach the desktop so the question is without slide=0 is no problem or we still use slide=XXX ? edited: Sorry I can boot with slide=128 thanks all to dev You're fantastic 1 Link to comment https://www.insanelymac.com/forum/topic/284656-clover-general-discussion/page/644/#findComment-2565839 Share on other sites More sharing options...
Sherlocks Posted January 10, 2018 Share Posted January 10, 2018 You must use old AptioFix or AptioFix2 pre r4369 for anything older than ML. EDIT: Also just don't use AptioFix after r4369 at all. It will produce side effects. i checked side effect. new aptiofix has lang issue on osx. shown eng+kor combination. now i return back old aptiofix to boot both SL and HS thanks Link to comment https://www.insanelymac.com/forum/topic/284656-clover-general-discussion/page/644/#findComment-2565854 Share on other sites More sharing options...

Funky frank Posted January 10, 2018 Share Posted January 10, 2018 About spectre / meltdown slowdown: https://reverse.put.as/2018/01/07/measuring-osx-meltdown-patches-performance/ Properly benchmarked. It means that all syscalls will be drastically slower, so assumingly audio i/o, disk i/o, memory allocation?. The speed will be even more reduced with 10.13.3, since it contains more security mechanisms. I hope they will continue to trying to find faster ways, but i doubt that, because they already developed for the last 6 months or so. I am still not entirely sure, why it seens to be not enough to simply patch the outside communicating apps like browser, email, etc. Please notice that running geekbench is not an accurate measuring for this problem.

13parsecs Posted January 10, 2018 Share Posted January 10, 2018 Yeah, it's not persistent unless it's flashed with the firmware. ... It alone is not going to protect from the vulnerability, because the problem is in the actual silicon of the chip, so the memory map can be side-channeled through speculation. The memory map needs to be separated from any other memory map if you want to not have this vulnerability. "Cache me outside, how 'bout dat?" Thanks for all your great work Apianti, Slice, Vit, RM, RHM, DFritz, CCPW, et al.

Slice Posted January 10, 2018 Share Posted January 10, 2018 Hey guys, is there a standard way to pass arguments to the binary of a macos kext? Or a standard section for that in the info.plist of the kext? There are several ways. All of them "standard". Constant parameters written into info.plist IOKitPersonality section. See hundreds macOS examples. Tunable parameters can be passed through DeviceTree. This is the way TouchPad get options from PrefPane. DynamicParameters can be passed changed by IOUserClient interface. (RadeonDump for example). As well it can be shared memory access (VoodooHDA PrefPane). Moreover it can be SMC exchange, Apple's way. Or other methods... Now, about plug and play Thunderbolt...? IOPCIFamily.kext assumes fixed PCIe configuration while Thunderbolt devices assumed to be PCIe devices. 1 Link to comment https://www.insanelymac.com/forum/topic/284656-clover-general-discussion/page/644/#findComment-2566069 Share on other sites More sharing options...

Because what app doesn't communicate with icloud now or some other apple service? Their newest FIRMWARE for the iMacPro will require internet... I think that the entirety of the operating systems developer community and the chip engineers who have discussed the best way to solve this have probably come up with the best solution, separating the memory spaces so that they cannot be attacked. They will develop ways to make system calls less frequently and overall you are probably not even really going to notice anything once it settles down. Don't forget that software has a life cycle and macOS is currently going through a redesign phase anyway so it is kinda good that it happens during now, their next release will most likely be very excellent. "Cache me outside, how 'bout dat?" So dumb... lol. Thanks for all your great work Apianti, Slice, Vit, RM, RHM, DFritz, CCPW, et al. Now, about plug and play Thunderbolt...? What about it?

Read like three lines below where you linked in the source. you are right. i just confirmed it. if i remove EmuVariableUefi-64.efi there is no prev-lang:kbd key in nvram. before i update beta4, i removed EmuVariableUefi-64.efi and nvram.plist to surely check where is problem. and default kor lang before update beta4. when updating beta4, i saw english word example "install 14 minutes left". after finished beta4, then booted, i just saw eng+kor combination of system part. example reboot dialog above pic. when used EmuVariableUefi-64.efi, always correct lang shown example "설치 14분 남았습니다" after finished beta4, then booted, i saw correct kor lang of system part without eng. i used this combination of EmuVariableUefi-64.efi+old aptioV2 long time. now, i returned old aptioV2 to avoid this issue after update lang issue. also i didn't notice keyboard problem that you mentioned keyboard. i just checked lang part. <key>Language</key> <string>ko:0</string> thanks EDIT1 this issue happen new aptiov1 and aptiv2. i tested skylake laptop and sandy laptop.

apianti Posted January 10, 2018 Share Posted January 10, 2018 I don't know why you showing me a picture of it makes it any more valid. First, the address can't go beyond 32bits so only eight hexadecimals, so 0x100000000 would be truncated to zero, which is definitely not valid. Second, the address has to be in the range 0x100000 to 0x20200000 aligned by 0x200000 because those are the only possible slide locations.

Slice Posted January 10, 2018 Share Posted January 10, 2018 I seems should not bother about slide value? Available 0000000000100000-0000000082D1DFFF 0000000000082C1E 000000000000000F Thanks a lot for that info! I was referring to these findings in NVDAResmanWeb.kext. What would you assume is the correct way to pass these arguments to that kext? You can send any argument to driver if it waits an argument from you.

Funky frank Posted January 11, 2018 Share Posted January 11, 2018 Hey slice, how is the noEFI setting passed to the nvidia web driver by clover? Is it a DSDT patch, or a binary patch or a argument passing? Found this in clover source: https://sourceforge.net/p/cloverefiboot/code/HEAD/tree/rEFIt_UEFI/Platform/nvidia.c#l2414 Looks like a device tree modification to me?

Funky frank Posted January 11, 2018 Share Posted January 11, 2018 Thanks. And what exactly is this DSDT key for: NVDA,Features I have seen it in old DSDTs, but it seems to be still present in NVDAStartupWeb.
