* lantiq: ltq-ptm: vr9: fix skb handling in ptm_hard_start_xmit()Martin Schiller2020-01-262-1/+4
| | | | | | | | | | Call skb_orphan(skb) to call the owner's destructor function and make the skb unowned. This is necessary to prevent sk_wmem_alloc of a socket from overflowing, which leads to ENOBUFS errors on application level. Signed-off-by: Martin Schiller <ms@dev.tdt.de>
* lantiq: Allow PKG_ASLR_PIE for DSL and voice driversHauke Mehrtens2019-11-016-7/+0
| | | | | | | | | | | When ASLR_PIE was activated globally these drivers failed to build because the user space LDFLAGS leaked into the kernel build process. This was fixed in upstream Linux kernel commit ce99d0bf312d ("kbuild: clear LDFLAGS in the top Makefile") which went into Linux 4.17. The lantiq target is now on Linux 4.19 only and these exceptions are not needed any more. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* lantiq: Fix fw_cutter LzmaWrapperChristian Franke2019-10-181-1/+1

* build: include BUILD_VARIANT in PKG_BUILD_DIRJeffery To2019-08-054-4/+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>
* lantiq: ltq-tapi: fix compatibility with Linux 4.15+Martin Blumenstingl2019-07-041-0/+48
| | | | | | | | | | | | | Linux 4.15 removes the init_timer() API. It's replaced by two functions: - timer_setup() is used instead of init_timer() and also replaces the timer "function" (callback) setup. - from_timer() has to be used to obtain the use-case specific data from a struct timer_list, which is now passed to the timer callback. Update the timer API to be compatible with Linux 4.15+ so it compiles with the upcoming Linux 4.19 kernel update. Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com>
* ltq-atm/ltq-ptm: re-enable/fix reset_ppe() functionality for VR9Martin Schiller2019-03-1014-65/+181
| | | | | | | | | | | | | | | 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.

* lantiq-vdsl-fw: update to provide recent vectoring firmwareDaniel Golle2018-06-153-11/+12
| | | | | | | | | | | | | | Recent Speedport firmware downloads only work over HTTPS, so the user either needs to provide the already downloaded file or install ustream-ssl-* as well as ca-certificates or ca-bundle. So to get VDSL2 with vectoring on xRX200, simply run vdsl_fw_install.sh on the target and either provide the downloaded file as instructed or make sure the device is connected to the Internet and can download that HTTPS url itself.

* 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: create ATM/PTM interfaces with dsl as netdev nameMathias Kresin2018-01-102-4/+4
| | | | | | | | | | | | | | | | | | | | | Renaming an atm etherbride using 'ip link' (via hotplug) is racy since the original netdev might disappear before br2684ctl has finished appling it's setting: local2.notice br2684ctl[1667]: Interface "nas0" created sucessfully local2.notice br2684ctl[1667]: Communicating over ATM 0.8.35, encapsulation: LLC kern.info kernel: dsl0: renamed from nas0 kern.err kernel: br2684:br2684_regvcc: tried to attach to non-existent device local2.err br2684ctl[1667]: Could not configure interface:No such device or address By passing the final used netdev name to br2684ctl_wrap another race condition workaround will be enabled again. Change the lantiq ptm driver to create a netdev with the name dsl as well. Albeit the rename via 'ip link' works fine so far, using a different approach for ptm then atm could be confusing.
