Linux/AM5728: PCIe too slow

HI,

The SDK is too old to support. Please update to the latest one, PSDK 5.3.0.7.

You may want to consider using DMA on the EP side. For DMA on RC side, you can refer to the discussion in this thread:
e2e.ti.com/.../2250836

For PCIe performance, on linux side, we only have PCIe Ethernet bandwidth measurement
software-dl.ti.com/.../Release_Specific_Performance_Guide.html

RTOS PDK measures PCIe to PCIe and it's in PDK PCIe example in RTOS SDK. You can run it and get the number.

Hi, Zhengguang,

Yes, I am talking about PCIe on A15 running Linux, except no data for PCIe performance. The only Linux PCIe performance measured is using PCIe ethernet card to measure Ethernet performance over PCIe.

If you want PCIe performance info, TI only has measurement using RTOS PDK PCIe example which gives you the PCIe measurement. It will be between 2 EVMs. For details, you will need to take a look at the RTOS PCIe example.

For linux, you may want to try implementing DMA as I suggested in previous posts.

Hi, Zhengguang,

PSDK 3.1 is too old to support. Please upgrade to the latest 5.3 release.

Have you run PDK PCIe example yet? Does the performance meet your expectation?
