* cns3xxx: ethernet - clean up tx descs only when neededFelix Fietkau2014-02-271-4/+8
| | | | | | | | | | | We already clean up tx descriptors in the napi eth_poll() function so it would likely be rare to run out of available descriptors in eth_xmit. Thus we can clean them up only when needed and return busy only when we still don't have enough. Signed-off-by: Tim Harvey <tharvey@gateworks.com> SVN-Revision: 39762
* cns3xxx: ethernet - resolve SMP issueFelix Fietkau2014-02-271-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The combination of r35942 and r35952 causes an issue where eth_schedule_poll() can be called from a different CPU between the call to napi_complete() and the setting of cur_index which can break the rx ring accounting and cause ethernet latency and/or ethernet stalls. The issue can be easilly created by adding a couple of artificial delays such as: @@ -715,6 +715,7 @@ static int eth_poll(struct napi_struct *napi, int budget) if (!received) { napi_complete(napi); +udelay(1000); enable_irq(IRQ_CNS3XXX_SW_R0RXC); } @@ -727,6 +728,7 @@ static int eth_poll(struct napi_struct *napi, int budget) rx_ring->cur_index = i; wmb(); +udelay(1000); enable_rx_dma(sw); return received; This patch moves the setting of cur_index back up where it needs to be and addresses the original corner case that r35942 was trying to catch in an improved fashion by checking to see if the rx descriptor ring has become full before interrupts were re-enabled so that a poll can be scheduled again and avoid an rx stall caused by rx interrupts ceasing to fire again.

* imx6: optimize for NEON FPU hardwareLuka Perkov2014-02-271-1/+1
| | | | | | | | | | The IMX6 SoC uses an ARM Cortext-A9 which has both NEON and VFPv3 hardware blocks. This will tune gcc to use neon instead of vfpv3 which will outperform VFPv3. Signed-off-by: Tim Harvey <tharvey@gateworks.com> SVN-Revision: 39760
* imx6: enable FPU for hard floatLuka Perkov2014-02-273-4/+7
| | | | | | | | | | | | | | The OpenWrt build system uses MACHINE_FEATURES of fpu to set the HAS_FPU which in turn sets the default of CONFIG_SOFT_FLOAT as well as uClibc configuration. As the IMX6 SoC has both vfpv3 and NEON hardware support we want to add fpu to the feature list. This will default the IMX6 target to use -mfloat-abi=hard which will the be most efficient use of floating point. When switching to hard float, we also need to enable VFP support in the kernel.

* ar71xx: fix failsafe acces on several devicesGabor Juhos2014-02-251-1/+35
| | | | | | | | | | | | | | The ar71xx platform always uses the eth0 interface to provide access to the device in failsafe mode. Due to this, failsafe access is broken on devices where the LAN ports are connected to the 'eth1' interface. Update the relevant script to correctly set the ifname variable for these devices.
