The PPE (packet process engine) hardware block is available in Qualcomm
IPQ chipsets that support PPE architecture, such as IPQ9574 and IPQ5332.
The PPE in the IPQ9574 SoC includes six ethernet ports (6 GMAC and 6
XGMAC), which are used to connect with external PHY devices by PCS. The
PPE also includes packet processing offload capabilities for various
networking functions such as route and bridge flows, VLANs, different
tunnel protocols and VPN. It also includes an L2 switch function for
bridging packets among the 6 ethernet ports and the CPU port. The CPU
port enables packet transfer between the ethernet ports and the ARM
cores in the SoC, using the ethernet DMA.
Please make sure the code builds cleanly with W=1.
Yes, the patch series is successfully built with W=1 for ARM and ARM64
on my local workspace.
make CROSS_COMPILE=arm-linux-gnueabi- ARCH=arm W=1
make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 W=1
However, from the patchwork result as below, it seems the dependent
patch series (for FIELD_MODIFY() macro) did not get picked to validate
the PPE driver patch series together. This dependency is mentioned in
the cover letter. Could you advise what could be wrong here, which is
preventing the dependent patch to be picked up? Thanks.
