S10-DX-Kit PCIe driver failure

Hi Sir,

By right user should not change the value of these register.

I checked Table 109. PCIe Configuration Space Registers for x16/x8/x4 Controllers

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_ptile_pcie_avst.pdf#page=174

For address 0x100, it is Advanced Error Reporting (AER), and according to PCIe spec, these register is RO only (see screenshot as below).

So, write will not takes effect.

If you really want to write into these register, you may check PCIe spec which register attributes is RWs. Furthermore, if you simply change the register value might cause the system to crash.

Lastly, for new question, it is better if you can create a new thread. this is to ease conversation tracking and ease for other user to search related topic.
