Linux/TDA2PXEVM: SSD not seen when plugged into TDA2PEVA board

Stefan Laza

Part Number: TDA2PXEVM

Tool/software: Linux

Dear Ti,

we are trying to connect PCIe NVMe 3.0 x4 SSD into TDA2P eva board. We have done HW modifications in order to downgrade x4 ssd to work with x1 connector located on EVA board (shorted PRSTN2 and PRSNT1).

We have included NVME_support in kernel_menuconfig but after we boot the board, lsmod doesnt show this module and lspci fails to show SSD as well.

Do you have any proposals in orded to get this SSD to work?

SSD was verified in our PC with same linux version as it runs on the board (4.4.84).

We are using U.2 (SFF - 8639) SSD to PCI-E adapter and intel Optane SSD 900p.

Regards,

Stefan.

Hi Stefan,

Can you run the below command on the target and paste the output?

omapconf read 0x51002104

Also can you provide the kernel config used by running the below command (attach the file config.txt)

zcat /proc/config.gz > config.txt

Please also attach the DTB you're using.

Regards
Shravan

Hi Shravan,

here are the files and command results you have asked for.

root@dra7xx-evm:~# omapconf read 0x51002104
00000001

.dtb can not be attached here so i have changed the extension to .txt. However, that is an original dra76-evm-infoadas.dtb

Stefan.

Hi Stefan,

The config and the DT look fine. The link status (register read 0x51002104), seems to indicate that the EP isn't taken out of reset, thus lspci doesn't enumerate the SSD. Can you connect any other device and check if its working (network card etc)? Could you try any other SD card? Also can you attach the kernel logs on the target (when SSD isn't enumerated) by running 'dmesg'.

Also can you confirm the SSD being used is the one in the link below?
www.intel.com/.../900p-280gb-2-5-inch-20nm.html

Hi Shravan,

I confirm that we have used the Intel Optane SSD 900P from the link you have sent us.

We have used another SSD and we got it to work. This is the one - OCZ RevoDrive PCI-Express x4 50GB PCI Express MLC Internal Solid State Drive (SSD) OCZSSDPX-1RVD0050:

https://www.newegg.com/Product/Product.aspx?Item=N82E16820227596

However, this one has RAID controller on it.... the lspci, lsblk and omapconf commands while it is plugged in are shown below:

root@dra7xx-evm:~# lspci
00:00.0 PCI bridge: Texas Instruments Device 8888 (rev 01)

I have changed the config a bit so please take a look at the new attached file. Results of dmesg commands on both SSDs are also attached.

We still dont have any progress on Intel's SDD.

Thank you for the fast response. This is a real issue for us now.

Regards,

Stefan.

Hi,

Can you try these two experiments:

1. Can you configure PCIe on TDA2px to run in gen-1 mode, and see if its enumerated.

2. Apply the patch attached and see if it works (both in gen-1 and gen-2).

Regards

Shravan

The issue seems to be located in the clks we have changed in phy-ti-pipe3.c

See attached file.

Regards,

Stefan.

Hi Stefan,

Please try this patch (same patch as thread ). This patch ensures the same clock is input to the PCIe Phy and the SSD.

Any updates on running PCIe in Gen-1 mode (with and without the patch)?

Regards

Shravan

Hi Shravan,

the patch doesn't seem to help. The behavior is the same as before the 1st patch you have sent me. The board boots but lspci, lsmod etc does not show the SSD dev.

The behavior is the same regardless of the gen I use.

Do you have any other propositions?

Does board require any additional hardware changes? Shorting the PRSNT2 and PRSNT1 and grounding them?

Regards,

Stefan.

Hi Stefan,

I tried to connect HHL-form factor Intel Optan 900P SSD to our TDA2px EVM and it works (product description in link below, screenshot enumerating the device is also attached).

I guess there seems to be an issue with the interfacing of the SSD with the TDA2px EVM. What were the changes made to interface the SSD you're using with the EVM?

Regards

Shravan

0 Stefan Laza over 7 years ago in reply to Shravan Karthik

Intellectual 670 points

We are using this adapter:

www.amazon.com/.../B01D51HUUS

So can you please confirm this to us - you have just plugged in the SSD from your link and made the changes you have written in the previous post? What gen have you set in DTS?

Regards,
Stefan.

0 Shravan Karthik over 7 years ago in reply to Stefan Laza

TI__Genius 14650 points

Hi Stefan,

There were no changes made to the DTS. I tried with and without the patch provided in previous posts, and I was still able to get the device to show-up using lspci. The SSD we have (Intel Optane 900p with HHHL interface) slots into the PCIe connector on the TDA2Px EVM without the need for any adapter. My guess is the adapter isn't able to provide the voltage required to drive the SSD device (thus the link status is DETECT_QUIET -- register 0x51002104). Is it possible to use the HHHL interface SSD?

Regards
Shravan

0 Stefan Laza over 7 years ago in reply to Shravan Karthik

Intellectual 670 points

The adapter is just transferring signals from one connector to the other without any voltage adjustments. I doubt that this could be an issue. I have measured voltages and clks on the adapter and it seems that all is fine. I will measure again.

Then again, the only difference between our two SSDs is the packaging.

Do you have any other ideas?

Regards,
Stefan.

Hi Shravan,

Could you please send me your .config file so I can crosscheck it with mine?

Regards,
Stefan.

Hi Stefan,

Attached the config on my setup. Please note I didn't enable NVME as the goal was to check if the device is enumerated on PCIe.

Intellectual 670 points

Hi Shravan,

can you provide to us detailed output from lspci (e.g. lspci -vv) command when you connect the Intel Optane 900P SSD to TDA2PX EVA board?

We suspect that our Intel Optane 900p is not implementing the MSI interrupt structure, it only implements MSI-X.

The main reason why we suspect that the SSD is not implementing MSI interrupt structure is that the following function:

int pci_find_capability(struct pci_dev *dev, int cap);

is returning 0 when the cap parameter is set to PCI_CAP_ID_MSI, and returns 0x50 when the cap is set to PCI_CAP_ID_MSIX.

The pci_find_capability is called from pci_msi_setup_pci_dev function found in drivers/pci/probe.c.

Regards,

Stefan.

0 Shravan Karthik over 7 years ago in reply to Stefan Laza

TI__Genius 14650 points

Hi Stefan,

I've attached the lspci output.

Does your device support MSI? Since pci_find_capability for PCI_CAP_ID_MSI returns 0, it looks to me like the device doesn't support MSI.

MSIX isn't supported on the kernel version used by VSDK.

Despite MSI/MSIX capability, the device should be enumerated on the RC.

Regards

Shravan

Hi Shravan,

we also suspect that our Intel Optane 900P (U.2 15mm Form Factor) does not support MSI.

When we connect the SSD to TDA2P EVA (or TDA2XX EVA) board and rescan the PCI bus, we get the following log in dmesg:

[ 37.767052] pcieport 0000:00:00.0: BAR 14: assigned [mem 0x20200000-0x202fffff]
[ 37.774402] pcieport 0000:00:00.0: BAR 15: assigned [mem 0x20300000-0x203fffff pref]

[ 37.792124] pci 0000:01:00.0: BAR 0: assigned [mem 0x20200000-0x20203fff 64bit]
[ 37.800545] nvme 0000:01:00.0: enabling device (0000 -> 0002)
[ 37.806455] nvme 0000:01:00.0: Device failed to resume

We traced down the "Device failed to resume" in the NVME driver and this message is generated in nvme_dead_ctrl function.

The nvme_dead_ctrl function is called from nvme_probe_work function in the following line:

result = nvme_pci_enable(dev);
if (result)
goto out;
// ... function body ...
out:
if (!work_busy(&dev->reset_work))
nvme_dead_ctrl(dev);

The nvme_pci_enable function calls pci_enable_msix in the following line:

if (!pdev->irq) {
result = pci_enable_msix(pdev, dev->entry, 1);
if (result < 0)
goto disable;
}

and here we confirmed that the pci_enable_msix is returning a negative number (in our case it is -22) and this value
is also the return value of nvme_pci_enable.

For now it looks like our SSD is not supporting MSI.

Regards,
Stefan

Hi Stefan,

Can you try with CONFIG_BLK_DEV_NVME=n? Idea is to at-least ensure the PCIe controller is able to enumerate the device. Please ensure the config used is similar to the one attached (at-least ensure all configs necessary for RC mode operation are set).

Regards

Shravan

This means that the nvme driver is causing us problems.

Do you have any idea how to proceed with this issue?

Hi Stefan,

I haven't enabled NVME on my end either, and I get the same output as you do -- this is positive, as PCIe is able to enumerate the device.
Please give me a couple of days, I will enable NVME and try on my setup. I will provide updates early next week.

Regards
Shravan

Hi Milena, Stefan,

The device is enumerated on PCIe even when NVME is enabled. Attached the logs for the commands run on the target below.

I've attached the kernel config as well.

Shravan

Hi Shravan,

we compiled our kernel with your config, but the SSD is still not working.

We have a TDA2PX EVA board and two types of Intel Optane 900P SSD:
- Optane 900P PCIe card:

https://www.intel.com/content/www/us/en/products/memory-storage/solid-state-drives/gaming-enthusiast-ssds/optane-900p-series/900p-280gb-aic-20nm.html

- Optane 900P 2.5":

https://www.intel.com/content/www/us/en/products/memory-storage/solid-state-drives/gaming-enthusiast-ssds/optane-900p-series/900p-280gb-2-5-inch-20nm.html

We are connecting both SSD directly to the PCIe x4 connector on the TDA2PX EVA board and both SSD are not working with TDA2PX EVA board.

When we connect any of the above SSD and rescan the PCIe bus, we get the following message in dmesg:

root@dra7xx-evm:/sys/bus/pci# echo 1 > rescan
[ 464.656871] pci 0000:01:00.0: BAR 6: assigned [mem 0x20300000-0x2030ffff pref]

[ 464.675750] nvme 0000:01:00.0: Device failed to resume

Do you have any other idea what we could try?
Is there any possibility that you can send us your Linux image (maybe we are doing something wrong on our side)?

Regards,
Stefan

Hi Stefan,

I've attached the zImage and the modules for the corresponding image. Please try this out and let us know if it works. Copy the zImage to the boot folder in the rootfs partition and the modules to the lib/modules folder in the rootfs partition. (zImage.txt attcahed is zImage and modules.txt attached is modules.tar.gz).

I'm not sure if re-scanning the PCIe bus would work, is it possible to reboot the board rather than a rescan? Also how are you updating the config to reflect the configuration at my end?

Regards
Shravan

Hi Shravan,

we tried with your Linux image, but the kernel boot hangs on following line:

[    2.983062] mmcblk0: mmc1:0001 MMC08G 7.25 GiB
[    2.989397]   #0: DRA7xx-EVM

[    3.005781] mmcblk0: p1 p2
[    3.009443] Waiting for root device PARTUUID=229accf0-02...

Besides of rescanning the PCIe bus, we also try to reboot the board but the SSD is still not recognized.

We delete the old .config found in PROCESSOR_SDK_VISION_03_02_00_00/ti_components/os_tools/linux/kernel/omap

and copy your config file to this directory and rename it to .config

Now, from following location PROCESSOR_SDK_VISION_03_02_00_00/vision_sdk/build
we issue:
$ make kernel_menuconfig (here we don't do any modification, just close the menuconfig dialog and the build starts)
$ make linux_install

and after the build we copy the PROCESSOR_SDK_VISION_03_02_00_00/ti_components/os_tools/linux/targetfs to SD card.

Regards,

Stefan

TI__Genius 14650 points

Hi Stefan,

Can you update your MLO, u-boot.img and uenv.txt in the boot partition of the SD-card and see if the kernel boots?

To update the config can you run the below steps?

Add the below lines to ti_config_fragments/auto.cfg (present in the kernel repository)

CONFIG_BLK_DEV_NVME=m

CONFIG_PCI=y

CONFIG_PCI_ENDPOINT_TEST=y

CONFIG_PCI_DRA7xx_HOST=y

Then from vision-SDK run the below commands:

make linux

make linux_install

After running the above commands, update your SD-card using the steps mentioned in section 3.1 of VisionSDK_Linux_UserGuide.pdf in vision-SDK docs.

Regards

Shravan

Hi Shravan,

we tried your MLO, u-boot and uenv.txt but we don't
get any output, not event from bootloader.

We switched back to our MLO, u-boot and uenv.txt, we
also made suggested changes to ti_config_fragments/auto.cfg,
and after that we built the kernel using following commands:

$ make linux_clean
$ make linux
$ make linux_install

We copied everything to SD card (as described in VisionSDK_Linux_UserGuide.pdf), but the SSD is still not working on TDA2P EVM.

Stefan

TI__Genius 14650 points

Hi Stefan,

I've tested the SSD on my setup (on a TDA2P-EVM) and it works. Please apply this patch in the kernel and confirm if it works. (You can revert the other patches provided).

The issue seems to be with the clocks being configured for the SSD device. The controller was trying to access the configuration space of the SSD even before the clocks were setup causing an L3 error on the TDA2P-EVM.

By adding a delay, we ensure the access to configuration space of the EP (SSD), is after all clocks have been setup.

I've tested this for about 20 reboots, and I notice the SSD is enumerated each time (also see the NVME device enumerated in lsblk).

Regards

Shravan

Hi Shravan,

We have tried this setup at our place and have different behaviour with above mentioned two SSDs:

1. Optane 900P PCIe card: the same as the one that you have
-> gets enumerated each time

2. Optane 900P 2.5":
-> still does not work

We have also measured the write speed on the SSD (using dd comand and our test application((f)write)).
The bandwidth that we get is low (~150-200MBps).
We have removed gen1 from the dts files, but it seems that PCIe still remains as gen1, utilizing 1 lane.

Do you have any idea regarding this bandwith?

Regards,
Milena

0 Stefan Laza over 7 years ago in reply to Milena Milosevic

Intellectual 670 points

Hi Shravan,

we manged to configure the Optane 900P PCIe SSD to operate as GEN2 PCIe with 2 lanes, but

the speed is still the same (150MB/s ~ 200MB/s).

We observed that the L3 error appears on TDA2P EVA when we start writing to the SSD with dd command:

[ 63.004973] omap_l3_noc 44000000.ocp: L3 application error: target 5 mod:1 (unclearable)
[ 63.013136] omap_l3_noc 44000000.ocp: L3 debug error: target 5 mod:1 (unclearable)

Can you confirm what is the maximum write speed for your SSD using dd command?

We use the following command to test the writing speed:

dd if=/dev/zero of=/mnt/nvme/test.raw bs=128k count=100k

We didn't managed to get the Optane 900P 2.5" to work, we tried with msleep(10) and msleep(100) in pci_bus_read_dev_vendor_id function,

but without success. We always get the following message:

UPDATE:
We managed to get the Optane 900p 2.5" to work with TDA2P EVA board, we added few msleep to nvme_pci_enable function.
The write speed is still the same as above mentioned.

Hi Stefan,

Using two-lane mode, I'm seeing writing speeds of 260MBps when writing to ext4 file-system on the SSD. I ran the same 'dd' test-case as you did. The measured throughput for single-lane write to NVME device is documented to be ~128MBps on TDA2P.

Hi Shravan,

we didn't managed to get the SSD write speed above 260MBps when we are using PCIe GEN2 with two-lane mode.

With TDA2P we where expecting the SSD write speed to be at least 700MBps with PCIe GEN2 and two-lane mode,

but so far we are stuck at average speed of 200MBps.

We tested the Optane 900P SSD on our host computer (with Linux kernel 4.4.84 - same version as the kernel running on TDA2P) , with PCIe GEN2 x4 and the write speed was on average 1.4GBps, so

with two-lanes we where expecting the write speed to be 600MBps ~ 700MBps.

Is there any known limitation for TDA2P that doesn't allow us to obtain those 600MBps ~ 700MBps?

Regards,

Stefan

Hi Stefan,

The issue pertaining to enumeration of the SSD device seems resolved. I will look into the reason for the decreased throughput, and it will help if you can start a new thread, so that I can post my findings / solutions in that thread.

Hi Shravan,

we also think that the SSD enumeration problem is resolved.

New thread is created for the SSD write speed issue:

Thank you for your help on this issue.
