This patch set introduces MSI-X workflow.
This is a rework of previously published series 135422
(https://patchwork.freedesktop.org/series/135422/) and a continuation
of series 140877 (https://patchwork.freedesktop.org/series/140877/).
It includes:
1. Basic MSI-X workflow with GuC-to-host and "default MSI-X"
interrupt handlers.
2. MSI-X interrupts allocator to allow dynamic resource management.
3. uAPI flag to xe_exec_queue_create_ioctl that allows creating
an exec queue with its own MSI-X interrupt.
v2: Rebase + fix kernel doc issue
v3: Rebase + fix sriov_basic test failure
v4: Another attempt to fix sriov flows
v5:
- Rebase
- Optimize irq.enabled access (additional patch)
- Check irq.enabled in new IRQ handlers
- Code review comments (Piotr)
