In the past, there were similar failures reported by CI from other IGT tests, observed on other platforms. Before commit 63baf4f3d587 ("drm/i915/gt: Only wait for GPU activity before unbinding a GGTT fence"), i915_vma_revoke_fence() was waiting for idleness of vma->active via fence_update(). That commit introduced vma->fence->active in order for the fence_update() to be able to wait selectively on that one instead of vma->active since only idleness of fence registers was needed. But then, another commit 0d86ee35097a ("drm/i915/gt: Make fence revocation unequivocal") replaced the call to fence_update() in i915_vma_revoke_fence() with only fence_write(), and also added that GEM_BUG_ON(!i915_active_is_idle(&fence->active)) in front. No justification was provided on why we might then expect idleness of vma->fence->active without first waiting on it. The issue can be potentially caused by a race among revocation of fence registers on one side and sequential execution of signal callbacks invoked on completion of a request that was using them on the other, still processed in parallel to revocation of those fence registers. Fix it by waiting for idleness of vma->fence->active in i915_vma_revoke_fence(). (cherry picked from commit 24bb052d3dd499c5956abad5f7d8e4fd07da7fb1)

En el pasado, hubo fallas similares informado por CI de otras pruebas de IGT, observado en otras plataformas. Antes de confirmar 63baf4f3d587 (\"drm/i915/gt: solo espere la actividad de la GPU antes de desvincular una valla GGTT\"), i915_vma_revoke_fence() estaba esperando la inactividad de vma-\u0026gt;active a trav\u00e9s de fence_update(). Ese compromiso introdujo vma-\u0026gt;fence-\u0026gt;active para que fence_update() pudiera esperar selectivamente en ese en lugar de vma-\u0026gt;active, ya que solo se necesitaba la inactividad de los registros de cerca. Pero luego, otra confirmaci\u00f3n 0d86ee35097a (\"drm/i915/gt: Hacer que la revocaci\u00f3n de la valla sea inequ\u00edvoca\") reemplaz\u00f3 la llamada a fence_update() en i915_vma_revoke_fence() con solo fence_write(), y tambi\u00e9n agreg\u00f3 que GEM_BUG_ON(!i915_active_is_idle(\u0026amp;fence-\u0026gt;active )) Al frente. No se proporcion\u00f3 ninguna justificaci\u00f3n sobre por qu\u00e9 podr\u00edamos esperar que vma-\u0026gt;fence-\u0026gt;active est\u00e9 inactivo sin esperarlo primero. El problema puede deberse potencialmente a una carrera entre la revocaci\u00f3n de registros de valla por un lado y la ejecuci\u00f3n secuencial de devoluciones de llamadas de se\u00f1ales invocadas al completar una solicitud que las estaba usando por el otro, a\u00fan procesadas en paralelo a la revocaci\u00f3n de esos registros de valla. Solucionelo esperando a que vma-\u0026gt;fence-\u0026gt;active est\u00e9 inactivo en i915_vma_revoke_fence(). (cereza escogida del compromiso 24bb052d3dd499c5956abad5f7d8e4fd07da7fb1)"
