* ltq-atm: add Linux 5.0+ compatibilityMathias Kresin2020-03-161-0/+8
| | | | | | | | | Upstream commit 96d4f267e40f95 ("Remove 'type' argument from access_ok() function") removes the first argument to access_ok. Adjust the code so it builds with Linux 5.4.

* build: include BUILD_VARIANT in PKG_BUILD_DIRJeffery To2019-08-051-1/+0
| | | | | | | | | | | This changes the default PKG_BUILD_DIR to take BUILD_VARIANT into account (if set), so that packages do not need to manually override PKG_BUILD_DIR just to handle variants. This also updates most base packages with variants to use the updated default PKG_BUILD_DIR. Signed-off-by: Jeffery To <jeffery.to@gmail.com>
* ltq-atm/ltq-ptm: re-enable/fix reset_ppe() functionality for VR9Martin Schiller2019-03-106-23/+53
| | | | | | | | | | | | | | | This patch re-enables the reset_ppe() functionality for VR9 targets by using the new lantiq rcu subsystem. The reset sequence in the reset_ppe() function was taken from the ppa datapath driver of lantiq UGW 7.4.1. Additionally it adds the required reset definitions to the vr9 dtsi file. It also prepares the reset_ppe() function calls for the other lantiq targets. This feature is needed to be able to switch between ltq-atm/ltq-ptm driver in ATM/PTM Auto-Mode at runtime.

* ltq-atm: rewrite tx path to use IRQsAlexander Couzens2018-02-052-46/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ATM subsystem is different from the generic ethernet NICs. The ATM subsystem requires a callback when a packet has been sent. It means a tx skb_buff need to be used after it has sent. While the generic NIC can fill up the TX ring and free skb_buffs if it encounter a ring buffer slot with an already sent skbuff. The ATM drivers need call the pop() function after it has send a single ATM package. The ATM subsystem controls via this ways the queuing. The ppe engine use DMA channels for read and write. Every atm_vcc has it's own TX DMA channel and each TX DMA channel has it's own ring buffer. The old driver had multiple issues: - Call the subsystem callback at the beginning of tx function (ppe_send). Didn't allowed the ATM subsystem to control the enqueued package amount. - Filled up the TX ring until full and fail futher - copy or decouple the skb from all other subsystem before giving it over to TX ring The new tx path uses interupts. - call the subsystem callback _after_ it was sent by hardware - no need to copy our decouple the skb any more - gives back control to the atm subsystem over the enqueued packages - use an interupt for every sent atm package Using interupts shouldn't be a problem because of the slow uplink bandwidth of ADSL. The speed _through_ the DSL router was always as high as it should be, only traffic generated on the router itself were affected. After changing to new tx path, the speed of iperf's run on the router itself reached the same speed. The master/trunk wasn't as much affected because of TCP optimisations (reboot-5022-gb2ea46fe236a). The following results are taken on the remote server, which receives the stream over the internet and the DSL line.

* lantiq: ltq-atm: set carrier statusJohn Crispin2015-12-171-1/+14
| | | | | | | | | | | | | | This prevents the unconditionally start of pppd since netifd will be triggered if the device goes into showtime. The same applies to lost showtime as well. In compare to the ptm driver, this changeset isn't strictly required, since the "not in showtime" message is limited to the debug loglevel. But it reduces the amount of ppp related messages significant. Signed-off-by: Mathias Kresin <openwrt@kresin.me> SVN-Revision: 47916
