* treewide: rename POWER_ON_STRIP registerSungbo Eo2020-07-251-7/+7
| | | | | | | | | | AR8327 datasheet[1] calls the register at address 0x0010 "Power-on Strapping Register". As it has nothing to do with "strip", let's rename it to "POWER_ON_STRAP" to make it easier to grasp.

* generic ar8xxx: increase VLAN table for AR83x7David Bauer2019-11-301-2/+2
| | | | | | | | | | | | The Atheros AR8327 and AR8337 have (according to their datasheet) a VLAN table with a maximum of 4096 entries. Currently, there's a hard limit of 128 VLANs, which is the same as for most other Atheros switches. Increase this limit only for the AR83x7 series and modify some shared functions to allow them to work with a variable max VLAN count. Signed-off-by: David Bauer <mail@david-bauer.net>
* generic: ar8216: group MIB counters and use two basic ones only by defaultChuanhong Guo2019-05-201-0/+7
| | | | | | | | | | | | | | | | | There are too many MIB counters that almost nobody needs since commit d6366ce3665f ("generic: ar8216: mib_work_func: read all port mibs everytime"). In the worker function to poll MIB data, it deals with all ports instead of only one port every time, which introduces too many mdio operations that it becomes a heavy CPU load even on not-emulated MDIO bus. This commit groups MIB counters and enable only TxBytes and RxGoodBytes by default (both of which are necessary to get swconfig led working.) and adds an swconfig attribute to allow enabling all counters if users need them.

* generic: ar8216: add mib_poll_interval switch attributeChuanhong Guo2019-05-201-0/+7
| | | | | | | | | | | | | | This allows specifying interval of polling MIB counters from userspace and allow completely turning off MIB counter support by setting mib_poll_interval to 0. Since MIB counter polling is a heavy CPU load for GPIO emulated MDIO bus, disable this behavior by default. Those who wants to use swconfig LEDs can enable them with qca,mib-poll-interval dts property or with swconfig command. Fixes: FS#2230 ("kworker spikes 100% cpu every 2 second.")

* generic: ar8216: add support for get_port_stats()Chuanhong Guo2019-03-241-11/+6
| | | | | | | | | | | | | | | | | | | | | | | Partially reverts commit eff3549c5883a9abc5dbff00c084cabbcfdf4437. AR7240 and AR9341 have buggy hardware switch LED trigger. The AR7240 one doesn't blink and the blinking of port0/port5 is reversed on AR9341 if we swap PHY0 and PHY4. (Only blinking is reversed, which means LED for PHY0 will lit when PHY0 is link up and will blink when PHY4 has active link and vice versa.) On these two chips a software swconfig LED trigger is required. This commit adds swconfig port stats back but: 1. move checking of mib_t/rxb_id into ar8xxx_chip since we can't distinguish ar7240sw and ar8216 using only chip id. 2. don't update mib counter in get_port_stat. This function is called every 0.01s and this capturing procedure will take up a lot of CPU. We already have a mib_work_func updating mib counters every 2s so return the saved counter instead of fetching new data. The blinking rate will be weird but it should solve the previously mentioned CPU time problem. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>

| | | | | | | | | | | | | The intention of 967b6be118e3 ("ar8327: Add workarounds for AR8337 switch") was to remove the register fixups for AR8337. But instead they were removed for AR8327. The RGMII RX delay is forced even if the port is used as phy instead of mac, which results in no package flow at least for one board. Fixes: FS#1664 Signed-off-by: Mathias Kresin <dev@kresin.me>

* generic: drop support for get_port_stats() on ar8xxxThibaut VARENE2017-09-131-0/+9
| | | | | | | | | | | | | | | | The implementation is not efficient on ar8xxx switches. It triggers high CPU load and degrades device performance. The high CPU load has been traced down to the ar8xxx_reg_wait() call in ar8xxx_mib_op(), which has to usleep_range() till the MIB busy flag set by the request to update the MIB counter is cleared. This commit removes the get_port_stats() code introduced in 4d8a66d and leaves a note for future hacker's beware. Fixes: FS#1004 Signed-off-by: Thibaut VARENE <hacks@slashdirt.org>

* ar8327: Add workarounds for AR8337 switch.Vittorio Gambaletta2017-03-301-1/+41
| | | | | | | | | | | | | | | | RGMII RX delay setting needs to be always specified for AR8337 to avoid port 5 RX hang on high traffic / flood conditions. Also, the HOL registers that set per-port and per-packet-priority buffer sizes are updated with the reduced values suggested by the QCA switch team. Finally, AR8327 reserved register fixups are disabled for the AR8337. This patch is adapted from the Code Aurora QSDK, but with magic values mapped to proper defines.

* AR8216: make ARL age time configurableJohn Crispin2016-03-041-0/+9
| | | | | | | | | | | | | | | | | The default TTL for address resolution table entries is 5 minutes for all members of the AR8216 family. This can cause issues if e.g. Wifi clients roam to another AP and their MAC appears on another switch port suddenly. Then the client may not be reachable until the old ARL entry expires. I would have expected the switch to invalidate old entries if it detects the same MAC on another port. But that's not the case. Therefore make the TTL for ARL entries configurable. The effective TTL will always be a multiple of 7 seconds. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> SVN-Revision: 48913

| | | | | | | | | | | | | | In r45970 the MAC swap handling was made opt-in, however some boards have been forgotten during the conversion. Since the reference design uses this MAC swapping, and pretty much all known boards using this chip seem to do so too, enabling the swapping is a more reasonable default than leaving it disabled. Change the code to still allow boards to opt-out of this. Signed-off-by: Felix Fietkau <nbd@openwrt.org> SVN-Revision: 47956

| | | | | | | | | | | | | | | | | | | | | AR8337 supports a configuration bit to swap MAC0 and MAC6. Currently this is set in general if an AR8337 is detected and causes issues with devices using an AR8334 (internally an AR8337, just less chip pins). And it might even cause issues with AR8337-based devices with different board designs. Swapping the MAC's however isn't needed for AR8337 in general. It's just needed in case of certain board designs (affected devices seem to be based on Atheros reference board AP135/136-010). Therefore this configuration bit should be moved to platform data. The patch includes the needed changes to the device initialization code of affected devices. Hopefully I didn't miss any .. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> SVN-Revision: 45970

* ar8216: fix ATU flushingFelix Fietkau2015-01-241-1/+2
| | | | | | | | | | | | | | | | | | The functionality to flush the address translation table contains two bugs which luckily compensate each other. 1. Just setting the operation is not sufficient to perform the flushing. The "active" bit needs to be set to actually trigger an action. For the vtu operations this is implemented correctly. 2. ar8xxx_phy_read_status is called every 2s by the phy state machine to check for link changes. This would have caused an ATU flush every 2s. Fix the chip-specific ATU flush functions and remove the ATU flush call from ar8xxx_phy_read_status. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> SVN-Revision: 44101
