Dear Linux Kernel Community,
I hope this message finds you well. I am reaching out to seek assistance
with an issue I am experiencing with a PCIe device on my system.
System Details:
PCIe Device: PLDA Device 5555
Kernel Version: 5.4.0-148-generic
Distribution: Ubuntu 20.04.6 LTS
After booting the system, I read the Base Address Register (BAR) of the
PCIe device using the following command:
setpci -s 01:00.0 BASE_ADDRESS_0
Initially, the BAR value is 0xb0400000. However, after some time, reading
from the PCIe device's BAR memory fails and returns 0xffff (PCIe
memory-mapped registers read via the readb(), readw(), and readl() kernel
mode APIs returned 0xff\0xffff\0xffffffff). Upon rechecking the BAR using
the same setpci command, the result is 0x00000000. Additionally, I verified
the BAR0 address using the kernel API pci_resource_start(), and it
exhibited the same behavior.
Steps Taken:
Verified the device status using lspci -vvv -s 01:00.0:
# lspci -vvv -s 01:00.0

Request for Assistance: I would appreciate any guidance or suggestions on
how to further debug this issue. Specifically, I am looking for:
Potential causes for the BAR being reset to 0x00000000.
Steps to ensure the device is not being reset or put into a low-power state
unexpectedly.
Any additional diagnostic steps or tools that could help identify the root
cause.
Thank you for your time and assistance.
Best regards,
Naveen

If you're reading "all ones" from config space, it means the device is
inaccessible and the host bridge is returning this fabricated value after
a timeout.
> Kernel modules: m1801_pci
That's not a driver in the upstream kernel.
Maybe that driver allows the device to runtime suspend to D3hot,
which in turn allows its upstream bridge to also runtime suspend
to D3hot. Then the device would be inaccessible.

/sys/bus/pci/devices/0000:01:00.0/power/runtime_status
would tell you whether the device is runtime suspended.
Thanks,

Stepping- SERR- FastB2B- DisINTx-
Does this indicates that memory space (Mem-) and bus mastering
(BusMaster-) are disabled? Does it suggest the device might have
entered a low-power state?
I see runtime_status as active
#cat /sys/bus/pci/devices/0000\:01\:00.0/power/runtime_status
active

However, after some time, reading from the PCIe device's BAR memory fails and returns 0xffff (PCIe memory-mapped registers read via the readb(), readw(), and readl() kernel mode APIs returned 0xff\0xffff\0xffffffff). Upon rechecking the BAR using the same setpci command, the result is 0x00000000. Additionally, I verified the BAR0 address using the kernel API pci_resource_start(), and it exhibited the same behavior.
