MSI-X Test still fails after vector issue is fixed

[tanwar1981]

Team,
This issue is in reference to the "BSA Test 904: Test Fails even when MSI-X is initiated (Issue #105)". I am not able to reopen this issue so opening a fresh one.

Last we concluded that MSI-X vector value is generated wrong. Now after fixing that test still fails and doesn't give any clue why it failed.

We created latest System architecture image and ran test 1533 (earlier it was 904)

Here is the flow:

Environment: QEMU based environment where PCIe Avery VIP is acting as exerciser (System Verilog)

• MSI-X is enabled in SBSA register

pal_mmio_read Address = 81100000 Data = 0^M
pal_mmio_write Address = 81100000 Data = 80000000^M

Note: Here interrupt vector configured is 0

• EP exerciser initiates MSI-X with address 44091040 data 4C
  [QEMU] addr: 44091040: 4c 00 00 00

• Test fails with following message
  Interrupt trigger failed for : 0x204C, BDF : 0x10000

Attaching here the logs

Hi @tanwar1981 ,

Thank you for raising the query.

The reason for the test failure is that the MSI interrupt is not getting triggered [the exerciser instance 0x10000 has not triggered the interrupt]. Please note that the interrupt trigger is part of the PAL exerciser API's and it needs to be modified w.r.t your platform as the APIs in pal_exerciser.c are written for a specific exerciser reference design as described in Exerciser.md.
The file to update to suit your platform design is pal_exerciser.c. For more info please refer Exerciser API Porting Guide.

Thanks,
ACS Team

Hi @tanwar1981,

Just following up on the issue regarding the MSI interrupt and if you need any further clarifications from the ACS team.
