DarwinDumper

[Andy Vandijck]

I have fixed DirectHW and pciutils-3.7.0 for macOS Big Sur.

Should work on older versions too.

 

repo for DirectHW:

https://github.com/vampirecat35/DirectHW-BigSur.git

 

repo for pciutils-3.7.0:

https://github.com/vampirecat35/pciutils-osx.git

 

I've tested and updated it and works fine.

Attached is MacBookAir7,2 PCI dump (text file).

pciutils-3.7.0-MacBookAir7,2-dump.txt

 

By default it uses the standard Darwin accessor.

pcilib: Cannot open AppleACPIPlatformExpert (add boot arg debug=0x144 & run as root)

it works if the debug boot argument is set.

I included it as an alternative.

The intel-conf1 alternate accessor is using DirectHW.

Also DirectHW has been edited for 64-bit cpus to be able to use 64-bit IO.

I tested it using pciutils, it works.

You could replace the current version in DarwinDumper.

It should work with recompilation on any macOS version starting from 10.6.

I have built and tested Flashrom 1.2 for macOS.

flashrom v1.2 on Darwin 20.2.0 (x86_64)
flashrom is free software, get the source code at https://flashrom.org

Calibrating delay loop... delay loop is unreliable, trying to continue OK.

FREG4: Platform Data region (0x00001000-0x00001fff) is read-only.
Not all flash regions are freely accessible by flashrom. This is most likely

OK.
Found Winbond flash chip "W25Q64.V" (8192 kB, SPI) mapped at physical address 0x00000000ff800000.
Reading flash... done.

Attached is also the chip dump from my MacBookAir7,2.

 

Since I've used libpci from pciutils-1.7.0:

The app requires boot-args set to debug=0x144.

Also DirectHW.kext from me must be loaded.

It works quite well.

Enjoy

Great job Andy!

I'll take a look when I can.

[ic005k]

@blackosxHow can dumpACPI be used separately? Directly from dumpACPI to generate aml or dsl files? Thanks.

[blackosx]

I just realised my notifications needed enabling. I swear they were on before.

 

Well I guess you just need some knowledge of Objective-C which I don't have. But you do as you've created your excellent PlistEDPlus

 

My attempt six years ago was to look at PHPdev32's MacIASL and try to get working what I could use and that was to export a property list which I later extract to AML using bash and plutil. Decompilation of AML can be done using Intel's iasl.

 

MAcIASL is now hosted at acidanthera so take a look there and see what you can find.

What happened to the bitbucket repo? It is not accessible. 

[blackosx]

hmm.. whoah! WTF? Thanks for bringing it to my attention.

[blackosx]

@startergo It turned out that the repository was set to unavailable due to it being flagged as malware. Only after speaking with support and them running a virustotal scan did they confirm it was clean. The repository has now been reactivated.

 

Thanks again for letting me know.

I tested the files for Andy back in January and most tools worked fine. Testing again now using the latest hwtools-osx-10.9-and-above.zip here using MacBookPro13,2 on macOS 11.2.2 I can confirm flashrom works.

I tested the files for Andy back in January and most tools worked fine. Testing again now using the latest hwtools-osx-10.9-and-above.zip here using MacBookPro13,2 on macOS 11.2.2 I can confirm flashrom works.

I agree the version of flashrom in the DarwinDumper v3.1.1 does not work in BigSur and DarwinDumper does need to be updated one day, time allowing, but it still runs without the pcilib error you are seeing (though doesn’t successfully dump a ROM) . Here I've tested on the same MacBookPro as above with the DirectHW.kext and flashrom version in DarwinDumper v3.1.1

Interesting, I've not heard of dosdude's ROMTool until now.

As you showed me this tool I thought I try it and see it uses the old v0.9.7 version of flashrom, similar to current DarwinDumper

 

I installed it's version of DirectHW.kext to /L/E

No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

So the only combination of DirectHW and flashrom that's working for me on the latest version of macOS is ANV's new version.

So I removed the DirectHW from the /L/E folder and using RomTool:

Your log is very similar to ANV's above. It just looks like flashrom does not find your chip.

Interesting, I've not heard of dosdude's ROMTool until now.

As you showed me this tool I thought I try it and see it uses the old v0.9.7 version of flashrom, similar to current DarwinDumper

 

I installed it's version of DirectHW.kext to /L/E 

% kmutil showloaded | grep DirectHW 
No variant specified, falling back to release

Then tried running the ROMTool binary from the terminal as you did, but this failed

No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

So the only combination of DirectHW and flashrom that's working for me on the latest version of macOS is ANV's new version.

 

 

Your log is very similar to ANV's above. It just looks like flashrom does not find your chip.

It is not obvious from the log, but it produced a vbios backup. This is on a MacBookPro11,3. For some reason using Andy's directHW I get this error:

pcilib: Cannot find any working access method.

I have fixed DirectHW and pciutils-3.7.0 for macOS Big Sur.

Should work on older versions too.

 

repo for DirectHW:

https://github.com/vampirecat35/DirectHW-BigSur.git

 

repo for pciutils-3.7.0:

https://github.com/vampirecat35/pciutils-osx.git

 

I've tested and updated it and works fine.

Attached is MacBookAir7,2 PCI dump (text file).

By default it uses the standard Darwin accessor.

pcilib: Cannot open AppleACPIPlatformExpert (add boot arg debug=0x144 & run as root)

it works if the debug boot argument is set.

I included it as an alternative.

The intel-conf1 alternate accessor is using DirectHW.

Also DirectHW has been edited for 64-bit cpus to be able to use 64-bit IO.

I tested it using pciutils, it works.

You could replace the current version in DarwinDumper.

It should work with recompilation on any macOS version starting from 10.6.

Hi Andy! Great job!
Where release can be downloaded? Thanks!

Hi @blackosx,

New version dmidecode 2.13 (I don't know real version enumeration so I just set 2.12 + 1)

Changes

1. Understand DDR4

2. Print ExtendedFirmwareFeatures.

3. The application is 64bits.

A small update

dmidecode.zipdmidecode.c

I know that the version 3.2 is on Acidanthera site but compare the results

diff.txt

[kocoman]

can this tool dump these variables?

 

Debugger called: </Library/Caches/com.apple.xbs/Sources/GPUDriversIntel/GPUDriversIntel-16.0.31/IONDRV/IVB/AppleIntelFramebuffer/AppleIntelController.cpp:14147 Assertion failed: (0 == i) || ((pfbInfo->rangeStolen.physBase - pfbInfoPrev->r

(0 == i) || ((pfbInfo->rangeStolen.physBase - pfbInfoPrev->rangeStolen.physBase) == fFramebufferMemorySize)

 

thx
