[PATCH 0/3] MSI-X support

[PATCH 0/3] MSI-X support

[Levi, Ilia]

This patch set introduces MSI-X workflow.
This is a rework of previously published series 135422
(https://patchwork.freedesktop.org/series/135422/).

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.

  drm/xe: Initial MSI-X support for HW engines
  drm/xe: Manage MSI-X interrupts allocation

 From email headers:

	User-Agent: Mozilla Thunderbird

It looks like you have a setup issue - each patch was sent individually
rather than providing the correct In-Reply-To, so this not a proper
series our CI understands and that can be easily applied.
It's better to use git-send-email for our email-oriented workflow.
