    [Help] AppleALC Kernel Panic after Catalina update

    No more detailed docs available. Version 1.4.3 added No-hda-gfx code. To activate it, you need to add the "No-hda-gfx" in the config.plist. It solves the kernel panic in Haswell chipset but it also disables HDMI audio. If your chipset is not Haswell, you don't need it. If you are using HDMI...

    [Help] AppleALC Kernel Panic after Catalina update

    If you don't need HDMI audio output, yes, you can use the official 1.4.3 release + the following setup(only example). You need to change both Pci(0x1b,0x0) and alc-layout-id 1 to something for your motherboard. <key>Devices</key> <dict> <key>Audio</key> <dict>...

    [Help] AppleALC Kernel Panic after Catalina update

    The kernel patch works but it's a temporary solution. Another bandaid solution is disabling the digital audio in IGPU with "No-hda-gfx" but it's better than the kernel patch. Put the kext in EFI/C/K/Other, and insert the following code in config.plist / Devices / Properties / PciRoot / (data=0)...

    It should just work as the touchscreen is connected to an internal USB. Check if the USB port is opened in /E/C/A/Patched/SSDT-UIAC.aml. My laptop model use HS08 for the touchscreen.

    If you are using Logitech wireless USB keyboard, update Logitech Control Center Software first. Or you will be stranded in the middle of nowhere. You can't login because the keyboard doesn't work. Mouse works. I found an old wired keyboard in my basement but that was a big hassle.

    [Guide] High Sierra / Mojave on Dell 5570

    Thanks for the info. Very slow boot could be solved by the v2.2.12 BrcmPatchRAM2.kext and BrcmFirmwareData.kext in /E/C/K/O. I'm using DW1830. The source and release file could be downloaded from headkaze/OS-X-BrcmPatchRAM.

    [Guide] High Sierra / Mojave on Dell 5570

    The driver is too sensitive to work in all laptop. It works fine in my laptop now but it doesn't mean it will work in others. I found several other issues but I couldn't fix it because it doesn't work correctly if I fix it. I could feel the pain in the ass of devs. (Attached is a recompiled file).

    Here is the kext for 10.13+ support. The previous one was linked with 10.14+ SDK. My initial plan was only to fix the lagging issue but I'm getting into too deep... :banghead: (edited: removed file)

    [Guide] High Sierra / Mojave on Dell 5570

    If the release file v2.2 in the official github runs in the High Sierra but this doesn't, there might be something else in there. Do you think it's related with this issue? -> "VoodooI2CHID Doesn't Load After Update"

    [Guide] High Sierra / Mojave on Dell 5570

    I re-uploaded the file to include a commit to fix a loading issue when installed in /Library/Extensions. The devs source were linked with an old source of VoodooGPIO. It didn't include a modification done recently by devs. Without it, it couldn't be loaded in /L/E. I'm not sure if it's related...

    Attached here is compiled targeting 10.13+. I guess there are still a few possibilities loosing some tracking but it should be smoother. Thanks for the update.

    [Guide] High Sierra / Mojave on Dell 5570

    Could you download and test it one more time? I recompiled it. Could you give me more details? Lagging? Jumping? Multitouch feeling? Stopping? Freezing? Sensitivity? or Very minor movements?.... It could be related with the bugs or just because of other commits after 2.1.4... but I hope to find it.

    VoodooI2C Help and Support

    Removing two of getWorkLoop() in both VoodooGPIO.cpp and VoodooI2CControllerDriver.cpp solves the issue. It works well. But, there would be more than that to solve it completely.

    VoodooI2C Help and Support

    I could fix the lagging/freezing happened since 2.1.4+ but you've been discussing it here. The commits causing the lagging are two, which was done on 12/23/2018. IOWorkLoop* VoodooGPIO::getWorkLoop() { ...... } IOWorkLoop* VoodooI2CControllerDriver::getWorkLoop() { ..... } Simply removing...

    Ok, I fixed the bug in VoodooI2C.kext. Attached file is Version 2.2 including the latest commits (Aug 11, 2019) and the fix. Touchpad movement in my laptop has no lagging, no delay, no freezing. (edit) file removed. refer next posts.

    I guess you reached the right spot. The default is 0x1. You can change it to 0x2. The "Video Memory" on the UEFI information screen didn't mean "DVMT pre-alloc". It's only 32MB if you haven't changed the value. By the way, I paid $25 for a genuine DW1830 card on ebay. I was lucky.

    (edited) I've done several tests (Note: Not all 5570s have the same specs. Mine is i5-8250u, 1920x1080 screen, with touch screen(connected to internal USB), touchpad DELL0810(Synaptics Precision) at _SB.PCI0.I2C0.TPD0). 1.
