From 7286b2518ec8e4398b512ce95def9166a7af2e4a Mon Sep 17 00:00:00 2001 From: Deepak S Date: Thu, 13 Jul 2017 21:26:50 -0700 Subject: Adding PROX(Packet pROcessing eXecution engine) VNF to sampleVNF JIRA: SAMPLEVNF-55 PROX is a DPDK-based application implementing Telco use-cases such as a simplified BRAS/BNG, light-weight AFTR... It also allows configuring finer grained network functions like QoS, Routing, load-balancing... (We are moving PROX version v039 to sampleVNF https://01.org/intel-data-plane-performance-demonstrators/prox-overview) Change-Id: Ia3cb02cf0e49ac5596e922c197ff7e010293d033 Signed-off-by: Deepak S --- VNFs/DPPD-PROX/rw_reg.h | 43 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 VNFs/DPPD-PROX/rw_reg.h (limited to 'VNFs/DPPD-PROX/rw_reg.h') diff --git a/VNFs/DPPD-PROX/rw_reg.h b/VNFs/DPPD-PROX/rw_reg.h new file mode 100644 index 00000000..1e38c7d0 --- /dev/null +++ b/VNFs/DPPD-PROX/rw_reg.h @@ -0,0 +1,43 @@ +/* +// Copyright (c) 2010-2017 Intel Corporation +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. +*/ + +#ifndef __RW_REG_H__ +#define __RW_REG_H__ + +/* Simplified, from DPDK 1.8 */ +struct _dev_hw { + uint8_t *hw_addr; +}; +/* Registers access */ + +#define PROX_PCI_REG_ADDR(hw, reg) \ + ((volatile uint32_t *)((char *)(hw)->hw_addr + (reg))) +#define PROX_READ_REG(hw, reg) \ + prox_read_addr(PROX_PCI_REG_ADDR((hw), (reg))) +#define PROX_PCI_REG(reg) (*((volatile uint32_t *)(reg))) +#define PROX_PCI_REG_WRITE(reg_addr, value) \ + *((volatile uint32_t *) (reg_addr)) = (value) +#define PROX_WRITE_REG(hw,reg,value) \ + PROX_PCI_REG_WRITE(PROX_PCI_REG_ADDR((hw), (reg)), (value)) + +static inline uint32_t prox_read_addr(volatile void* addr) +{ + return rte_le_to_cpu_32(PROX_PCI_REG(addr)); +} + +int read_reg(uint8_t portid, uint32_t addr, uint32_t *reg); +int write_reg(uint8_t portid, uint32_t reg, uint32_t val); +#endif -- cgit 1.2.3-korg
