From cba46af9d5570d672cf576c1f5cc31e6f332ebcc Mon Sep 17 00:00:00 2001 From: Han Wang Date: Sat, 19 Oct 2024 16:46:01 -0700 Subject: [PATCH] Fix p4c driver issues - remove duplicated bmv2/psa.p4 and dpdk/psa.p4 - remove calling bfas in p4c-driver - disable a few driver tests Co-authored-by: Glen Gibb Co-authored-by: Prathima Kotikalapudi Co-authored-by: Han Wang --- backends/tofino/bf-p4c/CMakeLists.txt | 13 +- backends/tofino/bf-p4c/driver/barefoot.py | 10 +- backends/tofino/bf-p4c/driver/p4c.tofino.cfg | 2 +- backends/tofino/bf-p4c/driver/p4c.tofino2.cfg | 2 +- backends/tofino/bf-p4c/driver/p4c.tofino3.cfg | 30 -
