2015-03-11dpaa_eth: fix static declarations for onicRotariu Marian Cristian-B44860
The function should be properly declared as being extern or static. The lack of scope identifier will result in a sparse error.

2015-03-11offline_port: convert dt into CPU endiannessRotariu Marian Cristian-B44860
The device tree values are stored in BE format by the dt compiler. In order to support different architectures, not only BE, the values read by the offline port driver should be converted into CPU endianness. This patch convert the dt values into CPU endianness and fixes some sparse errors related to endianness.

2015-03-11dpaa_eth: convert fq dts entries to CPU endianessRotariu Marian Cristian-B44860
The data related to fqs from dts are in BE. In order to be used by the CPU, the data need to be converted into CPU endianess. Because the current fqids structure is used in many ways and in many files, the code for endianess conversion is not localized. To make this patch as simple as possible, an intermediary variable was used.

2015-03-09FMD: Reset FManV3L DEFAULT_totalFifoSize to default 156KJianhua Xie
In T1040RMDPAAAP_Rev.C, at page 103, Figure A-38 says that the Reset value of FMan_V3L of BMI Configuration 1 Register (FMBM_CFG1) is 0x026F0000, which implies that FBPS should be 0x26F = 623. So the size of free buffer pool is 624 * 256bytes = 156KB, and 156K = 5*0x6400 + 0xa00 + 2*0x3200 = 5*1G + 1*OH + 2*OP. So it is OK to most cases while keep the default reset value for FMBM_CFG1. Without this vaule, sometimes DPA Eth driver (offline port) and FMD driver might report errors like below while more than 1 offline ports are added in t1040rdb/qds dts. dpa-fman0-oh@2 { compatible = "fsl,dpa-oh"; /* Define frame queues for the OH port*/ /* <OH Rx error, OH Rx default> */ fsl,qman-frame-queues-oh = <0x68 1 0x69 1>; fsl,bman-buffer-pools = <&bp6>; fsl,qman-frame-queues-tx = <0x90 8>; fsl,fman-oh-port = <&fman0_oh2>; }; dpa-fman0-oh@3 { compatible = "fsl,dpa-oh"; fsl,bman-buffer-pools = <&bp6>; /* Define frame queues for the OH port*/ /* <OH Rx error, OH Rx default> */ fsl,qman-frame-queues-oh = <0x52 1 0x53 1>; fsl,fman-oh-port = <&fman0_oh3>; }; /* The following OP is used as inbound OP*/ dpa-fman0-oh@4 { compatible = "fsl,dpa-oh"; fsl,bman-buffer-pools = <&bp6>; /* Define frame queues for the OH port*/ /* <OH Rx error, OH Rx default> */ fsl,qman-frame-queues-oh = <0x54 1 0x55 1>; fsl,fman-oh-port = <&fman0_oh4>; }; DPA offline port reports errors as below: ...... fsl_dpa_proxy: FSL DPAA Proxy initialization driver () fsl_oh: FSL FMan Offline Parsing port driver () fsl_oh dpa-fman0-oh.24: Found OH node handle compatible with fsl,dpa-oh. fsl_oh dpa-fman0-oh.24: Allocating 0 ingress frame queues duples fsl_oh dpa-fman0-oh.24: OH port /soc@ffe000000/fman@400000/port@83000 enabled. fsl_oh dpa-fman0-oh.24: Default egress frame queue: 105 fsl_oh dpa-fman0-oh.24: Default error frame queue: 104 fsl_oh dpa-fman0-oh.24: Initialized queues: fsl_oh dpa-fman0-oh.25: Found OH node handle compatible with fsl,dpa-oh. fsl_oh dpa-fman0-oh.25: Allocating 0 ingress frame queues duples fsl_oh dpa-fman0-oh.25: OH port /soc@ffe000000/fman@400000/port@84000 enabled. fsl_oh dpa-fman0-oh.25: Default egress frame queue: 83 fsl_oh dpa-fman0-oh.25: Default error frame queue: 82 fsl_oh dpa-fman0-oh.25: Initialized queues: fsl_oh dpa-fman0-oh.26: Found OH node handle compatible with fsl,dpa-oh. fsl_oh dpa-fman0-oh.26: Allocating 0 ingress frame queues duples cpu1/1: !

2015-02-25dpaa_eth: adjust advanced drivers to older kernelMadalin Bucur
Support for multiple drivers per kernel module comes in kernel 3.14 so we are forced to generate several modules for the advanced drivers. This patch can be dropped when the code is rebased on a kernel newer than 3.14. The problem is with the MODULE_DEVICE_TABLE macro that only from 3.14 generates different named structured based on the name parameter.

The patch "net: gianfar: do not try to cleanup TX packets if they are not done" for 3.12-rt left out the return value for gfar_clean_tx_ring(). This would cause an error when building this module.

2015-02-13net: gianfar: do not try to cleanup TX packets if they are not doneSebastian Andrzej Siewior
What I observe is that the TX queue is not empty and does not make any progress. gfar_clean_tx_ring() does not clean up the packet because it is not completed yet. The root cause is that the DMA engine did not start yet (it was preempted before doing so) and that dumb loop, loops until that packet is gone. This is broken since c233cf4 ("gianfar: Fix tx napi polling"). What remains are spurious interrupts if CPU0 cleans up TX packages and CPU1 returns with IRQ_NONE.

2015-02-13net: gianfar: do not disable interruptsSebastian Andrzej Siewior
each per-queue lock is taken with spin_lock_irqsave() except in the case where all of them are taken for some kind of serialisation. As an optimisation local_irq_save() is used so that lock_tx_qs() and lock_rx_qs() can use just the spin_lock() variant instead. On RT local_irq_save() behaves differently so we use the nort() variant. Lockdep screems easily by "ethtool -K eth0 rx off tx off" What remains is missing lockdep annotation that makes lockdep think lock_tx_qs() may cause a dead lock.

2015-02-13drivers/net: vortex fix locking issuesSteven Rostedt
Argh, cut and paste wasn't enough... Use this patch instead. It needs an irq disable. But, believe it or not, on SMP this is actually better. If the irq is shared (as it is in Mark's case), we don't stop the irq of other devices from being handled on another CPU (unfortunately for Mark, he pinned all interrupts to one CPU).

2015-02-13drivers/net: fix livelock issuesThomas Gleixner
Preempt-RT runs into a live lock issue with the NETDEV_TX_LOCKED micro optimization. The reason is that the softirq thread is rescheduling itself on that return value. Depending on priorities it starts to monoplize the CPU and livelock on UP systems. Remove it. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2015-01-26dpaa_eth: add VSP compatibility for eth portsMarian-Cristian Rotariu
This patch provides compatibility for the Ethernet driver ports with the VSP capability. Until now, the FMan ports managed by the Ethernet driver were not able to properly configure VSP because of the buffer layout of the FMan ports used. When VSPs are not enabled, the RX and TX path buffer layout are different, the Ethernet driver maintains separate buffer layouts for transmission and reception. When VSPs are enabled on a certain FMan port, the buffer layouts for Rx and Tx should be the same, the same buffer layout being used inside a storage profile. In order to bypass this the VSP capability is disabled on the Tx path by setting ContextB to 0 in the FQ descriptor of the queues that are transmitting the frames to the Tx port.

2014-12-11gianfar: Disable Rx snooping for LS1Claudiu Manoil
It was observed that Rx snooping incurs a significant performance penalty. My suspicion is that it interferes with the DMA software coherency, currently performed by DMA-API. It is known that there are H/W coherency issues at least for the Tx side (see read data interleaving issue) which is why the software coherency is needed in the first place. This patch disables Rx snooping as well, as a workaround, until the root cause for the Rx side coherency related issue is found.
