As defined by the MANA Hardware spec, the queue size for DMA is 4KB minimal, and power of 2. And, the HWC queue size has to be exactly 4KB. To support page sizes other than 4KB on ARM64, define the minimal queue size as a macro separately from the PAGE_SIZE, which we always assumed it to be 4KB before supporting ARM64. Also, add MANA specific macros and update code related to size alignment, DMA region calculations, etc. Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Reviewed-by: Michael Kelley <mhklinux@outlook.com> Link: https://lore.kernel.org/r/1718655446-6576-1-git-send-email-haiyangz@microsoft.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

If you have a network (Ethernet) device belonging to this class, say Y.
|
|
|
|
Note that the answer to this question doesn't directly affect the
|
|
kernel: saying N will just cause the configurator to skip the
|
|
question about Microsoft network devices. If you say Y, you will be
|
|
asked for your specific device in the following question.

This driver supports Microsoft Azure Network Adapter (MANA).
|
|
So far, the driver is only supported on X86_64.
|
|
|
|
To compile this driver as a module, choose M here.
|
|
The module will be called mana.
