* cns3xxx: support isolated PCI interrupts on newer Laguna PCBsFelix Fietkau2014-09-021-0/+196
| | | | | | | | | | | | | | | | | | | The cns3xxx uses irq61 for pcie0_intr which in the case of a PCIe-to-PCI bridge ends up combining INTA/B/C/D on a single ARM CPU interrupt. This is not optimal when you have multiple cores. To overcome this limitation an enhancement was made on newer Laguna PCB's that support miniPCI cards to route the INTA/B/C/D signals to unique external ARM CPU interrupts which can help balance CPU core utilization and in some cases increase overall system performance or responsiveness.

* cns3xxx: ethernet - revert: clean up tx descs only when neededFelix Fietkau2014-04-291-8/+4
| | | | | | | | | | | | | This reverts commit 0772ab938c0aedd7f4cc7127059d6ce8cf929dfa. Trying to optimize calls to eth_complete_tx in this fasion causes a regression where when sending only the tx queue can get disabled until a packet is received. This original call to eth_schedule_poll() is scheduled so it should not cause a performance issue.

| | | | | | | | | | | 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.

* cns3xxx: fix an rx irq handling corner caseFelix Fietkau2013-03-101-5/+5
| | | | | | | | | | | | | | | | When an rx interrupt comes in, rx interrupts are disabled and NAPI polling is scheduled. During the NAPI poll, the driver first processes received frames in the ring, then fills the dma descriptor slots with new buffers and calls tx complete, before finally re-enabling rx interrupts and completing NAPI (if below the budget). If the hardware rx queue overflows before the napi complete is called, the hardware will not throw any further rx interrupts and rx processing stops completely. Fix this by keeping NAPI polling scheduled until it completes a poll without receiving any packets, and also handle NAPI completion before refilling rx or completing tx. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@35942 3c298f89-4303-0410-b956-a3cf2f4a3e73
