[Mesa-dev] [PATCH v2 0/9] anv: Implement VK_KHR_external_semaphore

[Jason Ekstrand]

This patch series implements support for VK_KHR_external_semaphore for
Intel.  The series relies on DRM syncobj and, while we do have fallbacks
for if the kernel does not support syncobj, I do want to land syncobj
support in mesa before enabling the xtension.  This way we can rely on the
device->has_syncobj check to decide whether we're doing BO-based semaphores
or syncobj without having to worry about what the driver on the other side
of the import/export supports.  If you have VK_KHR_external_semaphore, then
you support both modes.

Jason Ekstrand (9):
  anv: Add a basic implementation of VK_KHX_external_semaphore
  anv: Submit a dummy batch when only semaphores are provided.
  anv/gem: Use EXECBUFFER2_WR when the FENCE_OUT flag is set
