Public bug reported:
SRU Justification
[Impact]
NVIDIA kernels are used on systems that require support for the
Microsoft Azure Network Adapter, including on ARM64 systems with support
for 64K and 4K page sizes. Systems using MANA may also need to support
booting from it. Build-in the MANA driver to the kernel image to support
booting, and include the listed fixes for the MANA driver to support
both 64K and 4K page sizes and address a race condition.
[Fix]
UBUNTU: [Config] nvidia: Enable CONFIG_MICROSOFT_MANA and
CONFIG_MANA_INFINIBAND on x86 and arm64
RDMA/mana_ib: use the correct page size for mapping user-mode doorbell page
RDMA/mana_ib: use the correct page table index based on hardware page size
net: mana: Fix RX buf alloc_size alignment and atomic op panic
net: mana: Fix race of mana_hwc_post_rx_wqe and new hwc response
net: mana: Add support for page sizes other than 4KB on ARM64
net: mana: Enable MANA driver on ARM64 with 4K page size
[Test Plan]
Compile tested on x86 and arm64. Kernel regression testing will be run
to verify there are no regressions from these patches on NVIDIA
hardware.
[Regression Potential]
These changes affect the MANA networking driver.
