No idea if HD3000 supports metal.
AppleIntelSKL is Skylake graphics, not HD3000.
Framebuffer data should match your actual prealloc setting. Suggest you read up on patching framebuffer and the data within.
I search a lot but no success.
I have one theory but I don't know what to looking for. I mention you like million times about freeze.
Problem only on EL CAPITAN !!!
Problem (different situations):
1. when I drag
maximise window on desktop horizontally that touched with menu bar
no freeze.
2. when I drag
maximise window on desktop vertically
but quick from menu bar to down about 3/4 bottom desktop and back to menu bar(can repeat this and no freeze)
no freeze.
3. when minimise window to about 80x80mm In this situation I can move window without problem (slow or fast)
no freeze.
4. when I repeat process like in 2. but this time slowly
freeze happened (depend how fast I drag) sometimes in 85% computer freeze that I
must hard shut down to press power button 4sec.
5. in safari sometimes when I download some app or file ... bubble animation starts when download started and freeze in the middle sometimes in 85% computer freeze that I
must hard shut down to press power button 4sec.
Here I can interrupt this animation and freeze if I open app or start some other operation immediately after download starts !!!
My Theories what cause this problem:
1.
Open GL not working (I don't know how to look and find in AppleIntelSNBGraphicsFB.kext and maybe is in other kext?
2.
Dead zone around menu bar. (this so called dead zone is around 5mm-10mm below menubar. Here freeze appear!
3.
Usb drivers or usb patches in dsdt cause this problem? Maybe.
4.
Resolution problem Apple not support 1600x900 in HD3000 mobile. (how to fix no clue!!!)
5.
Backlight patch. I'm 99% sure that this is the problem!!!
5. maybe nothing above theories are true but I believe that is fixable!
What I try so far:
- I change DMVT-prealloc set to 64mb in bios but nothing change.
- I change vram from 512MB to 1024MB and nothing change.
- I tried patch dsdt and ssdt form clover and linux dump. and nothing change.
What to do:
- I ll like to create new kext for blacklight but I don't have knowledge to do that.
- If is something to do with frame buffers I search some guide how to do. but now luck.
That it I hope someone know solution or time me direction how to solve this problem.
Just for intermezzo I have build Yosemite 10.10.5 which works just fine all mac functions works handoff, continuity, airdrop, ..... in the same hardware I just discuss for EL CAPITAN 10.10.5 problem with freeze!!!
RehabMan I know that only you reply to my posts and
Thanks for you effort so far! Where I must repost this post (under another topic or forum) to get help I need? You Know any friend which is specialised for graphics and editing buffers can you suggest?
