LoopBack

My setup of Dell Inspiron 7520 with Dell Wireless 1550 on OS X 10.10 DP2: 

• Latest Clover
• config.plist and DSDT: Yoseminspire.zip
• Kernel extensions in $ESP/EFI/CLOVER/kexts/10.10:
  • ACPIBatteryManger
  • ApplePS2ElanTouchpad
  • BTFirmwareUploader
  • FakeSMC
  • GenericUSBXHCI
• Kernel extensions in /S/L/E:
  • VoodooHDA
  • remove AppleHDA

 

System works flawlessly, Wifi and Bluetooth buggy when using Airdrop - well it's a DP

As always: discrete GPU disabled

Just want to leave a note here that this driver works great with OS X 10.10 DP2. EMlyDinEsH, your work is fantastic.

I switched back to my Dell Inspiron 7520 as Windows was affected by the problem as well, so I assume it was some kind of chipset or bios problem.

 

For reference I attached the last DSDT and SSDT i used.

DSDT+SSDT_Clevo.zip

Try using the attached DSDT. Which boot manager do you use? If you have problems with the DSDT, try booting with `-x` and dropping OEM SSDT.

Please upload an ioreg file using IORegistryExplorer(v2.1 or lower) and System log to take a look at your Sleep issue.

 

I attached the full ioreg xhc tree and the syslog during sleep and wakeup and sent you the ioreg files via PM (as they contain sensitive data, i'll not upload them publicly)

 

I also noted that the "sessionID" of the BCM20702A0 reg entry changes after every sleep/wakeup-cycle.

 

have you tried some of the boot flags if your using the genericusb3 kext? 

 

I use AppleXHCI right now,  but I tried with various boot flags on GenericXHCI and it did not help.

The E5440 uses the 771 server socket, not the 775. See http://ark.intel.com/compare/33082,33924

The Clevo W840SU is a low-voltage ultrabook, which allows to easily change hardware components (components are not - as usual for ultrabooks as well as macbooks - soldered onto the motherboard). It is reselled under various names, including Schenker S403, Tuxedo Book UC1402 and Nexoc B401.

BT - not included
WIFI - not included
LAN: Realtek RTL8111 - working, needs kext by Mieze
USB 3.0 - working, may cause crashes without DSDT patch on AppleXHCI
Sound: Realtek ALC282 - working, needs DSDT and AppleHDA patches
QE/CI - working, needs DSDT and SSDT patches
VGA - not included
HDMI - untested
Trackpad: Elantech v3 - working with kext by EMlyDinEsH
Sleep - working, super fast with apsd disabled
Battery - percent working with kext by RehabMan, The battery does not report any discharge information, causes OS X to complain about the battery to be empty, even if it will still last for hours. Easy DSDT work-around is to set a static discharge rate in case battery does not report any.
Camera - working, needs to be enabled using Fn-F10 first.
SD card reader: Realtek - not working
 
PCI device listing: lspci-nnvv-nowifi.txt IOReg: ioreg.txt
Patched DSDT: DSDT-SSDT.zip - Replace SSDT with table id "SaSsdt " to have QE/CI, DSDT contains patch for BCM4322x Wireless devices

I use OS X Mavericks.
 
After adding my Dell Wireless 1550 Wifi card, i have problems with standby: The notebook wakes up immediately. Since I got bluetooth up and running (using BTFirmwareUploader), wake up is deferred by about 30sec. From the syslog I still suspect bluetooth to cause the problem (wake reason is EHC1 XHC, with no usb device plugged in). I did not have this problem with my Dell laptop running OS X - maybe I'm missing a DSDT method? As I don't need bluetooth, I'd even like solutions, that break Bluetooth in favour of sleep mode.
 
Thanks in advance.

I'm running latest OS X 10.9.2 on my Inspiron 7520 upgraded to 16GB RAM. It's running great and smooth using the HD4000.

 

Custom kexts: ACPIBatteryManager, ApplePS2ElanTouchpad, FakeSMC, GenericUSBXHCI, VoodooHDA

I use Clover for DSDT Patching, see config.plist.zip, installation works without problems when booting from Clover, injecting the kexts mentioned above.

I use VoodooHDA, but I think AppleHDA should work as well with proper patching. I had no time to do it, so if somebody has some free time, the required codec file is here: codec0.zip

 

@repeor:

Power consumption: I achieve about 2 hours. You may want to check HWMonitor, during idle it should show a pacakge total power consumption of lower than 5W, if it's higher your CPU power management is not working properly. Another problem is that the discrete ATI GPU is powered on even if unused. If you're good at DSDT patching, you can call the acpi method "\_SB.PCI0.PEG0.PEGP._OFF" to turn discrete GPU off, i'm not aware of a osx side software method to do so. (If anybody knows better, please correct me!)

WiFi card: A friend of mine has a Inspiron 7520 with Dell Wireless 1550 inside. I think that it should be possible to use it, as the chip is similar to the original MacBook one (I'm going to check that next week)

Sleep: Works great for me (suspend is a little bit slow, but wakeup is fast as hell), maybe you miss some DSDT fix?
