Subject: [PATCH net-next v2 0/2] Add the capability to allocate hw buffers in SRAM for EN7581 SoC
Date: Fri, 09 May 2025 16:51:32 +0200 [thread overview]
Message-ID: <20250509-airopha-desc-sram-v2-0-9dc3d8076dfb@kernel.org> (raw)
In order to improve packet processing and packet forwarding
performances, EN7581 SoC supports allocating buffers for hw forwarding
queues in SRAM instead of DRAM if available on the system.
Rely on SRAM for buffers allocation if available on the system and use
DRAM as fallback.

Changes in v2:
- fix sparse warnings
- Link to v1: https://lore.kernel.org/r/20250507-airopha-desc-sram-v1-0-d42037431bfa@kernel.org
