Mavericks: Native CPU/IGPU Power Management

[toleda]

seems enabling the HD4600 got all the P-states working

CPU PM not related GPU PM (HD4600)

10.11.2/PM works on the same motherboard and processor; something is wrong with your configuration.

Where do you suggest I start? I did a fresh install off OS X and fresh Clover install - I've done two clean installs but no dice. Maybe it's a BIOS setting? I'm going to look there. I've also seen that people using F5 firmware have it working, I'll see if I can downgrade.

EDIT: looks like I can't downgrade. Will continue testing.

I'm having a weird issue trying to generate PM files for my system. When I run ssdtPRGen.sh (latest beta branch, v16.5), I'm getting lots iasl compiler errors, e.g.:

~/bin$ ./ssdtPRGen.sh

It appears that it's inserting lots of non-printable characters into the ssdt.dsl it generates, e.g.:

(emphasis added), which of course causes the errors when iasl attempts compilation. Any clue what might be happening, or is this just a bug in the script?

Any clue what might be happening, or is this just a bug in the script?

Did not see the problem on i5-4690S, version 13.5.

 

[nobodynose]

I figured out the ssdtPRGen.sh problem . I have had the environment variables

GREP_COLOR='1;35;40'

and

GREP_OPTIONS='--color=always'

set in my .bash_profile. ssdtPRGen.sh uses grep and egrep extensively, so the control patterns to generate the context highlighting was being inserted into its output (ssdt.dsl).

Once I changed

GREP_OPTIONS

to

'--color=auto'

, the problem went away and the script properly generates the SSDT again; I will suggest to Piker Alpha that he unset those two variables at the top of the script, just to be on the safe side.

However, my power management still doesn't seem to be working properly; the CPU's operating frequency is staying in the turbo frequencies all the time from what I can tell. Requested troubleshooting information attached.

I'm running OS X El Capitan 10.11.2 on an MSI H97M-G43 (MS-7924), BIOS v2.A with an i5-4590S CPU and a Gigabyte Nvidia GTX750 graphics card.

power management still doesn't seem to be working properly

IPG frequency scale/see Post #1/Notes/2. Clover/Intel Power Gadget
Issue is low freqs missing in AICPUPMI
BIOS settings/Optimized Defaults?
config.plist/ACPI/DSDT/Drop Tables/Tableid, edit CpuPm to CpuSsdt

 

[Warhammer73]

I tried the steps in the first posting, but

Verify

1. Console/Search: XCPM
   1. Code:
      kernel[0] XCPM: registered
      kernel[0] IOPPF: XCPM mode
      
      

is not working. Because XCPM is not available (have OS X 10.11.2)


Did I misunderstanding something?

Sorry for the late response - I just started a new job so I haven't been on the forums.

BIOS Settings/Optimized Defaults - CHECK
config.plist/ACPI/DSDT/Drop Tables/Tableid, CpuPm => CpuSsdt - CHECK

Intel Power Gadget still shows freq. staying in Turbo range when idle.

New diagnostic attachments added to message.

EDIT: Added to config.plist/CPU/QPI/100, which did fix the scale, but Power Gadget still staying between the max non-turbo frequency and the max turbo frequency.

I'm getting (interesting):

Jan 13 18:04:44 TimsHackPro kernel[0]: AICPUPMI: CPU P-States [ (8) 9 10 11 12 13 14 15 17 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 ]

yet Power Gadget still looks like this:

Power Gadget still staying between the max non-turbo frequency and the max turbo frequency.

Two separate experiments:
1. Set config.plist/KernelAndKextPatches/KernelPm/NO
2. Remove config.plist/ACPI/DropTables
Reply with new files

 

[Warhammer73]

I installed it like described in the first post.
But power gadget lucks like before.
Is it installed correctly and in use or do I have a problem?

Please have look at the attached files.

Thanks!


... but now my Intel Graphics is not working. No 3D acceleration and the system info said just 8MB of RAM for the graphic.

Edit:
After removing "ACPI/Set DropOEM" graphic is working.

Edit2:
With ACPI/Drop Tables

1. SSDT/CpuPm
2. SSDT/Cpu0Ist

Graphic is still working
