382d1741 - net: mana: Add support for page sizes other than 4KB on ARM64

Mon, 17 Jun 2024 20:17:26 +0000

net: mana: Add support for page sizes other than 4KB on ARM64As defined by the MANA Hardware spec, the queue size for DMA is 4KBminimal, and power of 2. And, the HWC queue size has to be exactly4KB.To support page sizes other than 4KB on ARM64, define the minimalqueue size as a macro separately from the PAGE_SIZE, which we alwaysassumed it to be 4KB before supporting ARM64.Also, add MANA specific macros and update code related to sizealignment, DMA region calculations, etc.Signed-off-by: Haiyang Zhang Reviewed-by: Michael Kelley Link: https://lore.kernel.org/r/1718655446-6576-1-git-send-email-haiyangz@microsoft.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ethernet/microsoft/Kconfig
