This series adds per-vPort Event Queue (EQ) allocation and MSI-X
interrupt management for the MANA driver. Previously, all vPorts
shared a single set of EQs. This change enables dedicated EQs per
vPort with support for both dedicated and shared MSI-X vector
allocation

modes.

Patch 1 moves EQ ownership from mana_context to per-vPort
mana_port_context and exports create/destroy functions for the RDMA

driver.

Patch 2 adds device capability queries to determine whether MSI-X
vectors should be dedicated per-vPort or shared. When the number of
available MSI-X vectors is insufficient for dedicated allocation,
the driver enables sharing mode with bitmap-based vector assignment.

Patch 3 introduces the GIC (GDMA IRQ Context) abstraction with
reference counting, allowing multiple EQs to safely share a single
MSI-X

vector.

Patch 4 converts the global EQ allocation in probe/resume to use the
new GIC functions.

Patch 5 adds per-vPort GIC lifecycle management, calling get/put on
each EQ creation and destruction during vPort open/close.

Patch 6 extends the same GIC lifecycle management to the RDMA
driver's EQ allocation path.

Changes in v5:
- Rebased on net-next/main

Hi Long Li,

Unfortunately v5 also doesn't apply cleanly to net-next.

Hi Simon,

This patch set should apply after this patch: (which is also pending net-next)
net: mana: Set default number of queues to 16

Can you apply the patch set after this patch, or should I wait for the next patch
merge window?

Thank you,
Long

I'll send it over in the next patch merging window.

Thanks,
Long
