| | | | | | | | | | | | | | | | | | | ARGC is a 'C-ism', but not known/valid in shell-syntax - insert the correct var $# (=number of args) here. under normal conditions this had no impact, but we should at least correct it. the error was observable like this: root@box:~ [ -e "/etc/functions.sh" ] && . /etc/functions.sh root@box:~ [ -e "/lib/functions.sh" ] && . /lib/functions.sh root@box:~ . /lib/upgrade/platform.sh root@box:~ . /lib/upgrade/common.sh root@box:~ platform_check_image /tmp/myfirmware.bin ash: bad number root@box:~ echo $? 0 Signed-off-by: Bastian Bittorf <bittorf@bluebottle.com> SVN-Revision: 40915
* 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. Signed-off-by: Tim Harvey <tharvey@gateworks.com> SVN-Revision: 40592

* cns3xxx: fix uImage build issueFelix Fietkau2014-03-051-1/+1
| | | | | | | | | | The uImage target will always fail on a clean build due to dependency issues. Building the uImage isn't necessary anyway as its re-built with correct entry points in image/Makefile so remove it. Signed-off-by: Tim Harvey <tharvey@gateworks.com> SVN-Revision: 39778
* 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.

| | | | | | | | | | | | In order to support both normal images and initramfs, ensure that each target sets KERNELNAME properly so that the generic kernel building code can copy the corresponding files over $(KDIR) with the appropriate extension.

* 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. SVN-Revision: 35942
