    DONOT-Review: Pin vram limit
    
    drm/xe/dma-buf: propagate pin error
    
    Return the error from xe_bo_pin_external() instead of asserting
    success, so callers observe failures such as -ENOSPC from the pin limit.

    drm/xe: add pin_vram_percent modparam
    
    Add a module parameter that caps the percentage of each VRAM region
    which may be pinned via dma-buf. A value of 0 disables the limit.

    drm/xe/vram: add pinned vram counters
    
    Add per-region counters tracking dma-buf and total pinned VRAM bytes
    along with the enforced dma-buf pin limit.

    drm/xe/vram: init dma-buf pin limit
    
    Derive the per-region dma-buf pin limit from pin_vram_percent during
    VRAM manager initialization.

    drm/xe/bo: account dma-buf pinned vram
    
    Track dma-buf pinned VRAM in the per-region counters on external
    pin and unpin.

    drm/xe/bo: account kernel pinned vram
    
    Track kernel pinned VRAM in the per-region total counter on pin
    and unpin.

    drm/xe/bo: enforce dma-buf pin limit
    
    Reject external VRAM pins that would exceed the per-region dma-buf
    limit with -ENOSPC.

    drm/xe/vram: show pinned vram in debug
    
    Expose the pinned VRAM counters and the dma-buf limit in the VRAM
    manager debug output.
    
    Signed-off-by: Himal Prasad Ghimiray <[email protected]>
    
    drm/xe/tests: add VRAM pin limit KUnit tests
    
    Test under-limit success, over-limit rejection, counter recovery after
    unpin, and the limit=0 unlimited case in xe_bo tests. Add an end-to-end
    dma-buf pin limit test in xe_dma_buf tests.
