The distance from the SGUnit to the Root port is constant.
calculating the Rootport and Cardbus based on this observation.
the root port and card bus are used by Warmreset function to

The following modifications were done as part of the fix
for warm reset.
1. Release sysman resources before quiscenting the GPU.
2. Add additional checks to confirm quiscenting of the GPU
before launching the diagnostics tests.
3. Fixed warm reset with wait time to allow the changes to be
propagated to the entire GPU PCI tree.
4. Modified the ULT's completely to avoid the usage of MOCKS.
5. Made Diagnostics handle creation per-device from per-SubDevice.

Before performing gpu device reset, first all level zero resources
and gpu device specific resources have to be cleaned up. Also as
after device reset, state of gpu device would be lost.
Hence after performing gpu device reset, level zero device have
to be reinitialized by querying gpu device again.
This change is aimed at reinitializing the level zero resources
after gpu device reset, so that user could continue using level zero
devices after device reset.

This patch does the following:
- Fixes a bug in FsAccess::listDirectory that could return
ZE_RESULT_UNKNOWN_ERROR when no error has occurred.
- Fixes a bug in zesDeviceReset that would reset the device
if force was set to false, even if the device was in use.
- Fixes a bug in zesDeviceReset that would reset the device
if force was set to false without closing the file descriptor.
- Added a releaseResources method method to Device object.
This method does the same thing as the DeviceImp
destructor except it does not free the DeviceImp object
and it does not free the SysmanDeviceImp object.
- Added the releaseResources methods to Mock<Device> object.
- Moved the reset of the debugger out of DriverHandleImp
destructor and into DeviceImp releaseResources.
- Added a releaseEngine method to the EngineHandleContext. This
method frees all the Engine handles.
- On reset, I call the Devcie->releaseResources and
EngineHandleContext->releaseEngines before resetting the device.
- Added a -r (--reset) option to zello_sysman so I
could easily test resets.
With these patches, the L0 Sysman CTS for zesDeviceReset
both pass.

Implemented function level reset.
Implementation is:
Make sure we are root (otherwise, return insufficient permissions)
Make sure no one has the device open
(otherwise, return hande object in use)
Close our file handle
Unbind the device from the kernel driver
Make sure no one still has the device open
(otherwise, kill them)
Perform function level reset (FLR)
Rebind the device to the kernel driver
