Amfeltec x16 PCIe with 4 SSDs: 5900+ MB/s

I consulted Nvidia, however it seems they can't understand that the issue only exist in Windows but not macOS. Therefore, can't be hardware limitation.

Maybe use shorter sentences and smaller words. I wonder if that guy knew what a VBIOS was before you mentioned it.

AFAIK, MVC know the exact switch in VBIOS to enable PCIe 2.0 in Windows. I still can't quite sure if VBIOS is a hard limit for the card to negotiate at PCIe 2.0 in Windows (because there has no such limitation in macOS).
Click to expand...
I suppose they wouldn't document the switch for us anywhere. Anyway, if macOS can make the card run at 5 GT/s without modifying the VBIOS, then Windows should be able to do the same...

You did not show the info for the Nvidia card. Compare the PCIe configuration space of the Nvidia device between macOS and Windows.
Code: 
sudo lspci -nnvvxxx -s 05:00.0
 
OK just checked on their Live chat and it really doesn't work with NVMe.

I’m sorry four doubting your impression handheldgames. It’s description is a bit misleading for newbies I guess.

I think I am in denial that we're all, Worldwide, stuck to Amfeltec Squid for $400... 🙁

Sorry about the post diversion and thanks for helping!

Thanks for sharing. Do you have a .sh file you can share? It would be great to use a modified version in a login script.

Hmmm...can't attach a .sh file? OK, the .txt extension works. Rename as you see fit. The script takes the port number you wish to change to PCIe v2 as argument. I've not put in any argument checking.

NOTE: a prerequisite of this script is to have pciutils installed and /usr/local/sbin in your PATH variable.

Here's the script text:

#!/bin/bash
# No arguments sanity checking done

rootport=$1
speed=2;

linkstatus=$(sudo setpci -s $rootport CAP_EXP+12.w);
echo '# Initial PCIe' $(( 0x$linkstatus & 15)).0 x$(( 0x$linkstatus >> 4 & 31))

sudo setpci -s $rootport CAP_EXP+30.w=$speed:F
sudo setpci -s $rootport CAP_EXP+10.w=20:20

linkstatus=$(sudo setpci -s $rootport CAP_EXP+12.w);
echo '# Final PCIe' $(( 0x$linkstatus & 15)).0 x$(( 0x$linkstatus >> 4 & 31))

Maybe i'm just dumb but what is wrong here ...
I've tried running the Valley application while running the pcitree.sh file and no matter what it seems that i'm stuck with 'g1x16' for my graphics card and I can't seem to change anything using setpci...

OpenGL extensions viewer shows all of about 350fps, valley is around 30fps ... driving 2 displays on this mac at 2550x1440 on GTX 650

Which I understand as being:
PCIe 1.0 x16

I see, I do have 2 different PCIe RAID controllers installed as well, I see the same inability to adjust anything PCI related.
I was thinking that I'd see the graphics change FPS or GFLop numbers if I could change it on the fly.
I was also running a blackmagic speed test on the hardware raid card (RAID10) at the time and didn't see read/write above 200MB/s peak, typically 175-185MB/s for both, using the built-in ESB2 SATA2 controller the 1TB 840 EVO can hit 250MB/s write 270MB/s read.
The second card is a 4 bay mSATA card, only populated with one mSATA3 drive but only is able to do about 120MB/s write, 180MB/s read.

I've received an amfeltec Gen3 quad M.2 card and did some tests. The lspci command (which I downloaded from https://github.com/pciutils/pciutils ) confirms that it starts at 2.5 GT/s x16 in slot 2 of my Mac Pro 2008.

The following command makes it go to 5 GT/s x16:
Code: 
# Set Target Link Speed of MacPro3,1 slot 2 root port to 5GT/s
sudo setpci -s 00:1 CAP_EXP+30.w=2:F

This fix could be put into EFI firmware, or a kernel extension. This fix eliminates any reasons to get the Gen 2 card (except price?) unless there is some other issue?

I'm waiting for more NVMe drives to test the 5 GT/s x16 performance because there is no difference with only one NVMe drive for the Gen 3 card when it runs on a link that can do 4 GB/s (2.5 GT/s x 16, 5 GT/s x8, 8 GT/s x4).

Has anyone done the above? Roll this fix into something that can be flashed into EFI firmware?

I followed the steps HERE and am now successfully booting off an NVMe. I'm guessing adding this PCIe lane fix would be similar? I'm clueless in this regard, and sadly can't even wrap my head around using Automator to type the text required for me. Is everyone just typing this in to terminal every boot? Thanks!

Not yet. First someone needs to write code for the kext or EFI driver. The EFI driver can be tested using a boot loader like rEFInd before committing it to firmware.

I think a google search will find examples for creating a startup script, a login item, or launch daemon.
http://www.launchd.info
You can hardcode the root port, or make it search for root ports (and maybe downstream ports) having link speed status less than link speed capability and having a subordinate device with a link speed capability greater than the root's link speed status then try setting the root's link speed target to the minimum of root's capability and subordinate device's capability.

138.0.0.0.0 probably does not apply to MacPro3,1 because Mojave is not supported on MacPro3,1 (and neither was Sierra or High Sierra).

Yes, I'm uncertain if that bootrom applies to the 3,1. This thread is nearly impossible to search as users put "3,1" in their signature line.

Mojave can be forced to install on 3,1 via the dosdude1 patcher. If that helps at all I'm uncertain.

I don't know by what means the 138.0.0.0.0 firmware is accomplishing pcie lane speed settings. Currently I have to utilize the pciutils suite and run:
Code: 
# Set Target Link Speed to 2.5GT/s of MacPro3,1 slot 1 root port
speed=2
rootport=00:5
linkstatus=$(sudo setpci -s $rootport CAP_EXP+12.w); echo '# Before: PCIe' $(( 0x$linkstatus & 15)).0 x$(( 0x$linkstatus >> 4 & 31))
sudo setpci -s $rootport CAP_EXP+30.w=$speed:F # Set Link Speed
sudo setpci -s $rootport CAP_EXP+10.w=20:20 # Start Retrain
linkstatus=$(sudo setpci -s $rootport CAP_EXP+12.w); echo '#  After: PCIe' $(( 0x$linkstatus & 15)).0 x$(( 0x$linkstatus >> 4 & 31))

The other additions to the 138.0.0.0.0 firmware look beneficial. Perhaps I'll ask over there if it can be wrestled into installing on a cMP 3,1...

138.0.0.0.0 enabled PCIe 2.0 support for all cards on a MP5,1.

No, you can't install a 5,1 firmware on a 3,1. No only the hardware is totally different, but MP3,1 firmware is 16MBit in size and 5,1 is 32Mbit.

Thanks! How about:

If it's not possible to install 138.0.0.0.0 on a cMP3,1, could whatever magic was performed on that firmware to enable proper PCIe lane speeds be done to my existing firmware, in a similar fashion as to how NVMe boot support was added?

NVMe and APFS support was a easy one. Both are structured as EFI modules, once Apple started to patching every supported Mac for those, people started to add both for the unsupported Macs the same way Apple did, just inserting the modules.

We still don't know how exactly Apple enabled support for PCIe 2.0 on Mac Pros 5,1, it's not a EFI module, but a change into the firmware itself.
[doublepost=1537638780][/doublepost]I doubt we will ever see MP3,1 firmware improvements like we are starting to do for 4,1/5,1. Apple used parallel flash memory with MP1,1 to 3,1, you have to desolder a chip with 42 pins, reprogram it with expensive programmers/adaptors and then solder again. For every brick you will have to re-do it. It will be very expensive and time consuming. Even if we install a ZIF socket on the logic board, loosing Wi-Fi and BlueTooth, still be a enormous effort to program the FWB flash memory externally at every brick.

For MP4,1 on wards, Apple used serial flash memories, only 8 pin, with cheap ($18 on Amazon/$9 AliExpress) programmers available. With less than $200 in hardware/supplies you can de-solder/reprogram/solder again. To eliminate this hassle, we're developing ways to reflash MP4,1/5,1/6,1 without having to solder/desolder.

It's not difficult to make a custom EFI module. Check the rEFInd or Clover boot loader projects.

What's the difference between firmware and EFI module? Isn't the firmware just a collection of EFI modules as seen in EFITool? I think the problem is that it's unknown which EFI module the change was made in. There are tools to extract all the modules in a firmware but they probably can't be easily compared (unless not all the modules were recompiled since the last firmware). The files have GUIDs for names, but some of those belong to standard EFI protocols (like EAF59C0E-BD46-413A-9AE9-DD9F6D1A927D is for Smbios). They should have code similar to that available in the EFI open source projects. Other files my have debug information that contain file paths (like 8B24E4D4-C84C-4FFC-81E5-D3EACC3F08DD is probably for ApplePlatformInfoDB because it contains a file path like "C:\buildtools\fware\m1main.proj\projectfiles\sandbox\Platform\IntelMpg\M1\Release\IA32\ApplePlatformInfoDB.pdb"). pdb is a debug information file used on Windows. The name helps to identify the purpose of the EFI file.

Isn't desoldering only required if the flash tool bricks your computer? Flashing just requires a software flashing tool like that used by Apple's firmware updates?

I thought those ways to reflash were already developed? In #312, cMP 31 4eva linked a google doc that mentions a RomTool that can be used to flash the MP3,1,MP4,1,MP5,1 with extra EFI modules (like for NVMe boot support).

Anyway, if flashing is not an option, EFI modules can probably be used with a boot loader like rEFInd.

Correct, but someone needs to do the grunt work and find it. Then test if it's possible to do the same with the MP3,1 firmware. Only one Russian guy was investigating MP3,1 firmware and I stopped testing things after two bricks.

MP3,1 firmware is a lot different from MP5,1, a lot of tricks, like with checksums, that I learned with the MP5,1, don't work with MP3,1. One of my MP3,1 bricks was trying to mod the hardware descriptor to the same way FL1100 is used in the MP6,1, to test USB3.0 boot. Used the same way to create checksums as with MP5,1, didn't work.

That never helped any of my bricks. It's designed to restore a failed firmware upgrade and even with that is of limited use. I have bricked once injecting a wrong jump point (MP4,1 LBSN/BD sector on a MP5,1 firmware, don't ask), that blocked the recovery routine in the firmware, couldn't even enter Firmware Programming mode.

I thought those ways to reflash were already developed? In #312, cMP 31 4eva linked a google doc that mentions a RomTool that can be used to flash the MP3,1,MP4,1,MP5,1 with extra EFI modules (like for NVMe boot support).

It's wonderfull GUI to flashrom. It's useful to flash a working firmware, but in the test phase, where you brick your Mac, it's useless.

I have bricked 2 MP5,1 and 2 MP3,1 in the last two months. Without a easy way to reflash a bricked Mac Pro without the need to desolder the flash memory, testing things rapidly become a bricking game.

With MP3,1 and the FWB TSOP42 flash memory, it's a lot more complicated to recover from a brick.

Anyway, if flashing is not an option, EFI modules can probably be used with a boot loader like rEFInd.

Yes, it's incredible useful to test if a NVMe EFI module is compatible with MP5,1. My second brick was testing iMac18,1 NVMe EFI module injected into MP5,1 firmware, after that I started to use rEFInd. But rEFInd can't help you if you're testing something into the private NVRAM area or with the LBSN/BD sector, for example.

Do you think the use of RomTool to add NVMe boot support as described in that google doc is safe enough? It seems to have worked well enough for cMP 31 4eva in a MacPro3,1, correct me if I'm wrong?

So, without figuring out how the new 138.0.0.0.0 firmware might have fixed this problem for MacPro4,1 and 5,1, a separate EFI module can be developed to solve the problem, tested using rEFInd, then optionally flashed with RomTool? A kext or launch daemon would probably be easier for users and could be necessary if sleep/wake causes the issue to reoccur.

Yes, it's safe to just add the NVMe EFI module with a MP3,1. Lot's of people are doing it with dosdude1 DXEInject.zip and APFS ROM Patcher.zip.

If you want a newer EFI module than the one from the Google docs, I have the most recent one from MP6,1 (MP61.0124.B00), ask me by PM. Works fine with 4,1/5,1, but test with rEFInd first.

I honestly prefer the launch daemon way, so much easier and safer to do than modding the MP3,1 firmware.

I even changed the part number of the RX580 in the bios to get the Orinoco framebuffer (which screwed the operation in Windows because the driver refused to start the card) and still can not get 5GT/s even though the linkCap is 8GT/s

Does anybody have an idea what is going on?

I even changed the part number of the RX580 in the bios to get the Orinoco framebuffer (which screwed the operation in Windows because the driver refused to start the card) and still can not get 5GT/s even though the linkCap is 8GT/s

Does anybody have an idea what is going on?

I think the command requires sudo like this:
Code: 
sudo ./fast.sh -s 00:03.0
