And which is the PCIE performance counter?

Instructions for finding the bus number of the uncore are provided in Section 1.9 of the "Intel Xeon Processor Scalable Memory Family Uncore Performance Monitoring Reference Manual" (document 336274-001, July 2017).

This "brute force" is not necessary, however.

Table 1-13 in Section 1.8.2 of the same manual lists the Device ID values for the PCI configuration space devices for the six DDR channel controllers. For each of the two IMCs, there are three channel controllers, with DIDs of 0x2042, 0x2046, and 0x204a. These devices are all present in the lspci output above. For example, Device 0x2042 shows that socket 0 uses bus 0x3a, while socket 1 uses bus 0xae:

3a:0a.2 System peripheral: Intel Corporation Device 2042 (rev 04)
3a:0c.2 System peripheral: Intel Corporation Device 2042 (rev 04)
ae:0a.2 System peripheral: Intel Corporation Device 2042 (rev 04)
ae:0c.2 System peripheral: Intel Corporation Device 2042 (rev 04)

The bus:device.function values for the "channel 1" (0x2046) and "channel 2" (0x204a) controllers are found the same way, and the pattern matches the documentation in Section 1.8.2. The offsets for the control and count registers are the same for each of the channels, and are also included in Table 1-13. The programming is described in Section 2.3, and is essentially the same as in previous systems.

How to unstand the "UNC_UBOX_package_to_bus_map[gid] = bus_no;" (from page 28 of document 336274 July 2017).

I only want to find the cpubusno. But it seems there is no bus_no.

McCalpinJohn · ‎08-25-2017

I have not tried to use the program that Intel provided to find the bus numbers, so it could be incorrect.

Fortunately you don't need it, since I already showed how to find the bus numbers from the lspci output.

I'm afraid of there are DID 2042, 2046, 204A on other platform. Is it only for this platform, and only for IMC?

McCalpinJohn · ‎09-05-2017

The DID is only supposed to uniquely identify a device for a specific vendor, so what you should search for the VID/DID pair. This is exactly what the code in Section 1.9.1 of the Xeon Scalable Processor Uncore Performance Monitoring Guide does.

In your lspci output at the top, DID 2042 occurs exactly 4 times, each time clearly identified an "Intel Corporation Device".

Not surprisingly, your version of "lspci" is able to find a translation for VID 8086 (Intel), so that part of the output is labeled.
Your version of "lspci" was not able to find an entry for an Intel device with DID 2042, so it only reported the numerical value of the DID for that device.
To skip the translation step and look at the raw data, you might try one or more of the following commands:
$ setpci -s 3a:0a.2 0x0.l
20428086
$ setpci -s 3a:0a.2 0x0.w
8086
$ setpci -s 3a:0a.2 0x2.w
2042
The four occurrences of VID 8086 / DID 2042 correspond to channel 0 on [IMC0 on socket 0, IMC1 on socket 0, IMC0 on socket 1, IMC1 on socket 1] -- exactly as expected.
The same pattern applies to VID 8086 / DID 2046 and VID 8086 / DID 204A, which correspond to channel 1 and channel 2 on the four memory controllers -- again exactly as expected.

Thank you GHui and Dr. Bandwidth for the discussion. > Instructions for finding the bus number of the uncore are provided in Section 1.9 of the > "Intel Xeon Processor Scalable Memory Family Uncore Performance Monitoring Reference Manual" > (document 336274-001, July 2017). There is a serious typo in the code given in this Section: #define DEVICE_ID_MASK 0xFFFF00000 // should be 0xFFFF0000 (foud Fs + four 0s). Also, a non-serious typo I found was: #define VENDOR_ID_MSASK 0x0000FFFF // should be MASK, not MSASK If someone from Intel is watchig this thread, please fix them.
