* cns3xxx: fix mtu setting with kernel 4.14Mathias Kresin2018-08-161-10/+1
| | | | | | | | | | | Since kernel 4.10 commit 61e84623ace3 ("net: centralize net_device min/max MTU checking"), the range of mtu is [min_mtu, max_mtu], which is [68, 1500] by default. It's necessary to set a max_mtu if a mtu > 1500 is supported. Tested-by: Koen Vandeputte <koen.vandeputte@ncentric.com> Signed-off-by: Mathias Kresin <dev@kresin.me>

* kernel: enable THIN_ARCHIVES by defaultSergey Ryazanov2018-05-221-1/+0

* treewide: remove obsolete sysupgrade watchdog killMathias Kresin2018-02-161-12/+0
| | | | | | | | | The watchdog kill command was meant for busybox watchdog. Busybox watchdog was replaced by the procd watchdog mid 2013 with commit df7ce9301a25 ("busybox: disable the watchdog utility by default"), which makes the kill command obsolete since quite some time.

Rework the network code to only enable IRQ's again if NAPI agrees it's safe to do so. Also only re-enable IRQ *after* cleaning up the RX ring and re-enabling DMA, which otherwise resulted in ugly warnings regarding dirty page fragments. These popped up nearly immediately when building the kernel with O2 iso Os. --> Note that this change fixes stability issues, at the cost of ~8% throughput performance. While at it, also change the iface name being used in warning prints, making it more obvious: "switch%d" --> "cns3xxx_eth" The changes have been tested on 4 boards, each moving ~30TB of data Signed-off-by: Koen Vandeputte <koen.vandeputte@ncentric.com>

* cns3xxx: fix GPIO controller interrupt enableTim Harvey2017-09-111-3/+3
| | | | | | | | | | | | | The cns3xxx interrupt controller uses a single register and as such the 'mask' reg/functions must be used as opposed to the 'enable'/'disable' reg/functions. This fixes an issue that occurs if more than one GPIO on a specific controller (there is GPIOA and GPIOB each having 32 GPIO's) uses interrupts. When one would get enabled all others would be disabled prior to this patch. Signed-off-by: Tim Harvey <tharvey@gateworks.com> Acked-by: Koen Vandeputte <koen.vandeputte@ncentric.com>
