[igt-dev] [PATCH i-g-t 1/2] test/device_reset: Rename device_fds to device_data

[Anshuman Gupta]

We need to encapsulate the the struct pci_device to device_fds
structure, which is a general helper data structure.
Rename its accordingly to device_data.
It will be used to encapsulate root port to support
warm reset IGT Test.

The pci code adds a minimum reset duration (Trst) delay after setting 
the bit. Do we need to add the same here?
https://elixir.bootlin.com/linux/latest/source/drivers/pci/pci.c#L5045

Is restoring sequence not necessary?

Thanks

Thanks for review.
Will add delay of 2ms to keep parity with the kernel.

> Is restoring sequence not necessary?
I think driver has the responsibility of restoring.
I am not sure about if IGT needs to restore it.
The test itself has sequence of unbind and bind, so driver should restore it.

Hmm, not too sure about this stuff but looks like we should follow the
entire sequence in the kernel function pci_reset_secondary_bus()? Thanks

Also is SBR done on the root port or the upstream bridge, in case there is
a bridge in the middle (between the root port and the device/bus)? In which
case this should be pci_device_get_parent_bridge()?

Reset de-assert is missing here. Reset need to be de-asserted after 
asserting it.

I was looking to the kernel source code , it seems by using /sys/bus/pvi/devices/$bdf/reset and /sys/bus/pvi/devices/$bdf/reset_method
sysfs we can trigger bus reset i.e warm reset. So we don't need to reinvent the wheel in IGT. So dropping the patch series.
