2013-04-12ENGR00257847-1 MX6Q/DL-Fix Ethernet performance issue when WAIT mode is activeRanjani Vaidyanathan
All of the interrupts from the ENET block are not routed to the GPC block. Hence ENET interrupts are not able to wake up the SOC when the system is in WAIT mode. And the ENET interrupt gets serviced only when another interrupt causes the SOC to exit WAIT mode. This impacts the ENET performance. To fix the issue two options: 1. Route the ENET interrupt to a GPIO. Need to enable the CONFIG_MX6_ENET_IRQ_TO_GPIO in the config. This patch provides support for routing the ENET interrupt to GPIO_1_6. Routing to this GPIO requires no HW board mods. If the GPIO_1_6 is being used for some other peripheral, this patch can be followed to route the ENET interrupt to any other GPIO though a HW mode maybe required. 2. If the GPIO mechanism cannot be used and is not enabled by the above mentioned config, the patch will disable entry to WAIT mode until ENET clock is active. When the ENET clock is disabled, WAIT mode will be automatically enetered. Signed-off-by: Ranjani Vaidyanathan <ra5478@freescale.com>

2013-03-06ARM: 7417/1: vfp: ensure preemption is disabled when enabling VFP accessWill Deacon
The vfp_enable function enables access to the VFP co-processor register space (cp10 and cp11) on the current CPU and must be called with preemption disabled. Unfortunately, the vfp_init late initcall does not disable preemption and can lead to an oops during boot if thread migration occurs at the wrong time and we end up attempting to access the FPSID on a CPU with VFP access disabled. This patch fixes the initcall to call vfp_enable from a non-preemptible context on each CPU and adds a BUG_ON(preemptible) to ensure that any similar problems are easily spotted in the future.

Connecting two boards directly more than 2 hours, Ar8031 phy link status generates glitch, which cause ethernet link down/up issue, but ethernet still be active. There have three cases to validate the issue: Item#1: If add performance stress test while runing IEEE1588, the link down/up issue cannot be found. Item#2: If insert switch between two net nodes and run IEEE1588 test, the issue also cannot be found. Item#3: If disable AR8031 SmartEEE feature, after two days overnight test, no such issue found. The issue is caused by phy Ar8031 SmartEEE feature, Item#1 and Item#2 can prevent phy enter lpm mode, which match the Item#3 test result, so disable SmartEEE feature to avoid the link issue generation.
