TDA4VEN-Q1: Pcitest fail issue between two J722s soc connection

?? ?

Part Number: TDA4VEN-Q1

Hi TI team,

We connect two TDA4VEN soc with 1-lane PCIe3.0 on our customized board. And the pcitest failed after the PCIe connection between two soc link up. Here are logs of RC and EP:

RC:

EP:

There are many fails when executing interrupt tests. And the pcitest process is stuck when executing read test. Pcitest binary and pcitest.sh shell script we used are located at <linux-kernel-source>/tools/pci in SDK1101.

Please help to validate the PCIe link between J722s EVM boards, thank you.

Regards,

Mingjian

The hardware design we used on EVM board can see this forum, it has the same issue on pcitest process.

Hi Mingjian,

The failing interrupts are expected.

Legacy interrupt - We removed due to a silicon errata i2094 which was first seen on J721E, but seen on other J7x devices as well: https://www.ti.com/lit/er/sprz455f/sprz455f.pdf?ts=1764885576311&ref_url=https%253A%252F%252Fwww.google.com%252F
MSI interrupt - If the SDK documentation is followed, then the default example only enables the first two MSI interrupts. Specifically, below two lines:
```
root@evm:/sys/kernel/config/pci_ep# echo 2 > functions/pci_epf_test/func1/msi_interrupts
root@evm:/sys/kernel/config/pci_ep# echo 2 > functions/pci_epf_test/func1/msix_interrupts
```
Increasing the number of MSI/MSI-X interrupts on EP-side should increase the number of passing interrupts.

As for the read test, it is unexpected that the test is stuck with read test. Could you try directly interacting with the pcitest binary instead of the bash script for troubleshooting? The read test can be initiated with a command like so: pcitest -d -r -s <size-in-bytes>

Regards,

Takuma

HI Takuma:
As shown in the attachment, we first configure on the EP side using setup-epf-func-VEN.sh, and then test on the RC side using pcitest.sh.

During debugging of data read and write, it was found that in pci_endpoint_test.c, in the function static irqreturn_t pci_endpoint_test_irqhandler(int irq, void *dev_id), the register value reg read from PCI_ENDPOINT_TEST_STATUS was 0, which caused the code to not reach complete(&test->irq_raised); Furthermore, during testing, the read and write successes happen randomly, but most of the time failures occur.

Please help explain what causes the PCI_ENDPOINT_TEST_STATUS register to read a value of 0 during the data read/write process, and who sets it? RC or EP?

Change all instances of wait_for_compilete in the code to wait_for_compilete_timeout, then perform PCIe read and write tests. The results are as follows, with OKAY and NOT OKAY appearing randomly each time.

Hi Quansheng,

quansheng zhu said:
Please help explain what causes the PCI_ENDPOINT_TEST_STATUS register to read a value of 0 during the data read/write process, and who sets it? RC or EP?

Below is a description of PCI_ENDPOINT_TEST_STATUS.

* PCI_ENDPOINT_TEST_STATUS

This register reflects the status of the PCI endpoint device.

========	==============================
Bitfield	Description
========	==============================
Bit 0		read success
Bit 1		read fail
Bit 2		write success
Bit 3		write fail
Bit 4		copy success
Bit 5		copy fail
Bit 6		IRQ raised
Bit 7		source address is invalid
Bit 8		destination address is invalid
========	==============================

The PCI_ENDPOINT_TEST_STATUS bits are set within the pci-epf-test.c driver that will run on the EP-side. The pcitest binary that is used by the bash script should send out a command to pci-epf-test by writing to the PCI_ENDPOINT_TEST_COMMAND register. On EP-side, they are then handled by the cmd_handler to call various functions depending on the command.

For troubleshooting, you could put some print statements below to see if the cmd_handler is getting called properly:

https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/drivers/pci/endpoint/functions/pci-epf-test.c?h=ti-linux-6.1.y#n643

Takuma

Hi Takuma,

We added the print in pci-epf-test.c and pci-endpoint-test.c. Seems like EP did not got the correct command when RC write it corrrectly.

The command printed from RC is using pci_endpoint_test_readl() after pci_endpoint_test_writel(). The read results are all correct. But sometimes EP could not get command from RC and did not enter the pci_endpoint_test_read() function. It caused the fail of RC's write test. The same issue happend in irq tests. RC should send irq commands for 4 times but EP only received twice. Please help analyse the issue.

Mingjian

Hi Mingjian,

I noticed previous logs when read/writes were done, MSI interrupts were set. Newer logs seem to be using MSI-X for read/writes. Could you set MSI before read/write, collect logs from read/write, and then test setting up MSI-X then collecting same logs for comparison? The debug prints that you have put in will be useful for the comparison.

I have recently heard of a customer issue that may be related to MSI vs MSI-X interrupt, so would be good to see if that is affecting the PCIe EP/RC example as well.

Regards,

Takuma

Hi Takuma ,

I tried using MSI-X instead of MSI, but seems that there is no difference.

On the other side , I think I found the root cause of read, write and copy test fail. When RC pci_endpoint_test driver wrote pci bar space , such as COMMAND, it sometimes took 0.5 second or longer then EP can read the COMMAND which RC wrote and go to deal with the COMMAND. Such delay also exists when EP wrote, RC read. So when EP finish the COMMAND function(read,write,copy), EP wrote SUCCESS to the status bit and raise irq to inform RC. But when RC receive irq, RC could not read the status bit as SUCCESS, so it return fail.

To validate the issue above, I disabled the irq callback and add 3s delay after RC send COMMAND to EP. After this modification, the read,write and copy test all success.

Based on the above tests, I think this is a cache consistency issue. Could you provide some infomation about that? We didn't meet such issue on SDK0805, 0902 and 1001 before.

Hi Mingjian,

I have some slight doubts about the cache coherency, but it is true that J722S has a slightly different architecture for cache than other TDA4 family devices, so will not rule out.

However, it sounds like a timing issue for pci_epf_test_raise_irq. I think line 600 of pci-epf-test assumes there is enough time for status register to get updated before the IRQ that is raised immediately after gets handled. Perhaps we need a polling while loop that reads the status register on EP side after the write to ensure the write has gone through before raising IRQ.

Regards,

Takuma

Hi Takuma,

In fact, we have already done a read back on the EP side before irq raised.

When EP side's prints are always right, RC sometime got the wrong STATUS value. So I think it's a cache coherency issue.

Regards,

Mingjian

Hi Mingjian,

If reading back the register gets correct value, then it does sound like a cache issue.

Could you try to put memory barriers in place to guarantee write goes through?
Could you share the dmesg logs from the RC-side?
Could you share the lspci -vvv logs from the RC-side?

Takuma

Hi Mingjian,

Looks like all of the memory regions are non-prefetchable, so it should not be doing prefetching:

Region 0: Memory at 600324600 (32-bit, non-prefetchable) [disabled] [size=256]
Region 1: Memory at 600324400 (32-bit, non-prefetchable) [disabled] [size=512]
Region 2: Memory at 600324000 (32-bit, non-prefetchable) [disabled] [size=1K]
Region 3: Memory at 600320000 (32-bit, non-prefetchable) [disabled] [size=16K]
Region 4: Memory at 600300000 (32-bit, non-prefetchable) [disabled] [size=128K]
Region 5: Memory at 600200000 (32-bit, non-prefetchable) [disabled] [size=1M]

On the other hand, I notice that the PCIe related boot logs occur later in the boot:

[ 948.472787] pci 0000:01:00.0: [104c:b010] type 00 class 0xff0000 PCIe Endpoint

To add on to previous post,

What is the procedure when enabling EP and RC? That is, what commands are ran in what order, on which board?
As for the memory barrier, you could use smp_mb() or other memory barrier related API.

Takuma

Hi Takuma,

The command we use:

EP first:

insmod pci-epf-test.ko

mount -t configfs none /sys/kernel/config

cd /sys/kernel/config/pci_ep/
mkdir functions/pci_epf_test/func1
echo 0x104c > functions/pci_epf_test/func1/vendorid
echo 0xb010 > functions/pci_epf_test/func1/deviceid
echo 2 > functions/pci_epf_test/func1/msi_interrupts
echo 2 > functions/pci_epf_test/func1/msix_interrupts
ln -s functions/pci_epf_test/func1 controllers/f102000.pcie-ep/

echo 1 > controllers/f102000.pcie-ep/start

Then RC:

insmod pci_endpoint_test.ko

echo 1 > /sys/bus/pci/rescan

Mingjian

Hi Mingjian,

Could you try building the kernel driver into the kernel instead of as a kernel module for both EP and RC? And do a power-on sequence of booting up EP first and configuring it fully, then after EP is up, turn on the RC?

Above should make it so that the RC should detect the EP during boot instead of having to manually run a rescan. The hotplug feature for the EP/RC is not robust.

Takuma

Hi Takuma,

I tried to build drivers into kernel and reboot RC after EP configured. Seems that there is no difference.

Hi Mingjian,

Thanks for trying. As for the memory barrier and cache coherency suspicion, were you able to try this out?

Takuma

Hi Takuma,

Is there any update on this issue?

By the way, I tried to use memory barrier and it did not work.

Hi Mingjian,

If manually invalidating cache does not work, I propose you handle within application.
