When app unmap vm ranges(munmap) kfd/svm starts drain pending page fault and not handle any incoming pages fault of this process until a deferred work item got executed by default system wq. The time period of "not handle page fault" can be long and is unpredicable. That is advese to kfd performance on page faults recovery. This patch uses time stamp of incoming page fault to decide to drop or recover page fault. When app unmap vm ranges kfd records each gpu device's ih ring current time stamp. These time stamps are used at kfd page fault recovery routine. Any page fault happened on unmapped ranges after unmap events is application bug that accesses vm range after unmap. It is not driver work to cover that. By using time stamp of page fault do not need drain page faults at deferred work. So, the time period that kfd does not handle page faults is reduced and can be controlled. Signed-off-by:

This commit applies isolation enforcement to the GFX and Compute rings in the gfx_v9_4_3 module. The commit sets `amdgpu_gfx_enforce_isolation_ring_begin_use` and `amdgpu_gfx_enforce_isolation_ring_end_use` as the functions to be called when a ring begins and ends its use, respectively. `amdgpu_gfx_enforce_isolation_ring_begin_use` is called when a ring begins its use. This function cancels any scheduled `enforce_isolation_work` and, if necessary, signals the Kernel Fusion Driver (KFD) to stop the runqueue. `amdgpu_gfx_enforce_isolation_ring_end_use` is called when a ring ends its use. This function schedules `enforce_isolation_work` to be run after a delay. These functions are part of the Enforce Isolation Handler, which enforces shader isolation on AMD GPUs to prevent data leakage between different processes. The commit also includes a check for the type of the ring. If the type of the ring is `AMDGPU_RING_TYPE_COMPUTE`, the `xcp_id` of the `enforce_isolation` structure in the `gfx` structure of the `amdgpu_device` is set to the `xcp_id` of the ring. This ensures that the correct `xcp_id` is used when enforcing isolation on compute rings. The `xcp_id` is an identifier for an XCP partition, and different rings can be associated with different XCP partitions.

This commit introduces the Enforce Isolation Handler designed to enforce shader isolation on AMD GPUs, which helps to prevent data leakage between different processes. The handler counts the number of emitted fences for each GFX and compute ring. If there are any fences, it schedules the `enforce_isolation_work` to be run after a delay of `GFX_SLICE_PERIOD`. If there are no fences, it signals the Kernel Fusion Driver (KFD) to resume the runqueue. The function is synchronized using the `enforce_isolation_mutex`. This commit also introduces a reference count mechanism (kfd_sch_req_count) to keep track of the number of requests to enable the KFD scheduler. When a request to enable the KFD scheduler is made, the reference count is decremented. When the reference count reaches zero, a delayed work is scheduled to enforce isolation after a delay of GFX_SLICE_PERIOD. When a request to disable the KFD scheduler is made, the function first checks if the reference count is zero. If it is, it cancels the delayed work for enforcing isolation and checks if the KFD scheduler is active. If the KFD scheduler is active, it sends a request to stop the KFD scheduler and sets the KFD scheduler state to inactive. Then, it increments the reference count. The function is synchronized using the kfd_sch_mutex to ensure that the KFD scheduler state and reference count are updated atomically.
