Added lockMemory in context to explicitly locking memory,
Added a boolean flag in graphics_allocation to indicate the allocation
is locked, and modified memory_operations_handler to add lock().
Change the logic to work correctly with makeResident() when lock() is
called previously for the same memory region

ULLS controller timeout settings will be adjusted based on ac line
status and lowest queue throttle from submissions.
Lowest queue throttle is reset when controller stops ULLS.

Modifed getResetStatus to abort only when scratch page is disabled
Removed an incorrect UNRECOVERABLE_IF statement based on the status:
validPageFault can be true when banned flag is not set, if CAT error
does not occur as a result of page fault.

Make bindless heaps resident right after heap allocation.
Motivation is that SYCL bindless image can be passed as a value argument
or through memory. Therefore, we're not able to make its bindless heap
resident during kernel initialization or setting kernel arguments.
This fixes SYCL bindless image read_write_*D.cpp tests on DG2.

Previous method used for retrieiving sub-device count in this path
did not take into account device affinity mask nor device hiearchy
mode, resulting in segmentation faults when attempting to allocate
rtDispatchGlobals structure using improper deviceBitFields.

driver is built with xe drm support by default
added cmake flag to control xe eu debug API support
NEO_ENABLE_XE_EU_DEBUG_SUPPORT
This flag is disabled by default and uapi-eu-debug headers are not
needed for driver compilation as these headers are not a part of
upstream kernel yet.

Add support for configuring ccs mode for all applicable devices
before KMD is loaded.
Use ZEX_NUMBER_OF_CCS to configure ccs mode.
Format is as follows:
ZEX_NUMBER_OF_CCS=NumberOfCcs i,e Setting ZEX_NUMBER_OF_CCS
to 4 sets ccs mode to 4 for all devices for which configuration
is supported.

Implemented to go through entire contexts in the process and then query
reset status to check the unexpected GPU segfault.
Added a new debug variable GpuFaultCheckThreshold to change the checking
frequency for each hang check for performance analysis.
