| * thermal: Use mode helpers in driversAndrzej Pietrasiewicz2020-06-291-20/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use thermal_zone_device_{en|dis}able() and thermal_zone_device_is_enabled(). Consequently, all set_mode() implementations in drivers: - can stop modifying tzd's "mode" member, - shall stop taking tzd's lock, as it is taken in the helpers - shall stop calling thermal_zone_device_update() as it is called in the helpers - can assume they are called when the mode truly changes, so checks to verify that can be dropped Not providing set_mode() by a driver no longer prevents the core from being able to set tzd's mode, so the relevant check in mode_store() is removed. Other comments: - acpi/thermal.c: tz->thermal_zone->mode will be updated only after we return from set_mode(), so use function parameter in thermal_set_mode() instead, no need to call acpi_thermal_check() in set_mode() - thermal/imx_thermal.c: regmap writes and mode assignment are done in thermal_zone_device_{en|dis}able() and set_mode() callback - thermal/intel/intel_quark_dts_thermal.c: soc_dts_{en|dis}able() are a part of set_mode() callback, so they don't need to modify tzd->mode, and don't need to fall back to the opposite mode if unsuccessful, as the return value will be propagated to thermal_zone_device_{en|dis}able() and ultimately tzd's member will not be changed in thermal_zone_device_set_mode(). - thermal/of-thermal.c: no need to set zone->mode to DISABLED in of_parse_thermal_zones() as a tzd is kzalloc'ed so mode is DISABLED anyway Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@collabora.com> [for acerhdf] Acked-by: Peter Kaestle <peter@piie.net> Reviewed-by: Amit Kucheria <amit.kucheria@linaro.org> Reviewed-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20200629122925.21729-8-andrzej.p@collabora.com

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If in the process of creating the underlay QP for an IPoIB interface the user has set the address and specifically the 1st-3rd bytes representing the QP number, use the requested QP number when creating the underlay QP. For a user to be able to request a QP number on QP creation, the MKEY_BY_NAME NVCONFIG should be set. As mkey_by_name and qp_by_name are coupled in FW. This requires driver to query the mkey_by_name max cap during initialization and set the current cap if it was enabled in FW.

But for testing the P/Q/R/S support, what I have is a reworked board with the SJA1105T replaced by a pin-compatible SJA1105Q, and I don't want to keep a separate device tree blob just for this one-off board. Since just the chip has been replaced, its RGMII delay setup is inherently the same (meaning: delays added by the PHY on the slave ports, and by PCB traces on the fixed-link CPU port). For this board, I'd rather have the driver shout at me, but go ahead and use what it found even if it doesn't match what it's been told is there.

PMTU discovery is currently broken with those configurations, because the encapsulation effectively decreases the MTU of the link, and while we are able to account for this using PMTU discovery on the lower layer, we don't have a way to relay ICMP or ICMPv6 messages needed by the sender, because we don't have valid routes to it. On the other hand, as a tunnel endpoint, we can't fragment packets as a general approach: this is for instance clearly forbidden for VXLAN by RFC 7348, section 4.3: VTEPs MUST NOT fragment VXLAN packets. Intermediate routers may fragment encapsulated VXLAN packets due to the larger frame size. The destination VTEP MAY silently discard such VXLAN fragments. The same paragraph recommends that the MTU over the physical network accomodates for encapsulations, but this isn't a practical option for complex topologies, especially for typical Open vSwitch use cases. Further, it states that: Other techniques like Path MTU discovery (see [RFC1191] and [RFC1981]) MAY be used to address this requirement as well. Now, PMTU discovery already works for routed interfaces, we get route exceptions created by the encapsulation device as they receive ICMP Fragmentation Needed and ICMPv6 Packet Too Big messages, and we already rebuild those messages with the appropriate MTU and route them back to the sender. Add the missing bits for bridged cases: - checks in skb_tunnel_check_pmtu() to understand if it's appropriate to trigger a reply according to RFC 1122 section 3.2.2 for ICMP and RFC 4443 section 2.4 for ICMPv6. This function is already called by UDP tunnels - a new function generating those ICMP or ICMPv6 replies. We can't reuse icmp_send() and icmp6_send() as we don't see the sender as a valid destination. This doesn't need to be generic, as we don't cover any other type of ICMP errors given that we only provide an encapsulation function to the sender While at it, make the MTU check in skb_tunnel_check_pmtu() accurate: we might receive GSO buffers here, and the passed headroom already includes the inner MAC length, so we don't have to account for it a second time (that would imply three MAC headers on the wire, but there are just two). This issue became visible while bridging IPv6 packets with 4500 bytes of payload over GENEVE using IPv4 with a PMTU of 4000. Given the 50 bytes of encapsulation headroom, we would advertise MTU as 3950, and we would reject fragmented IPv6 datagrams of 3958 bytes size on the wire. We're exclusively dealing with network MTU here, though, so we could get Ethernet frames up to 3964 octets in that case. v2: - moved skb_tunnel_check_pmtu() to ip_tunnel_core.c (David Ahern) - split IPv4/IPv6 functions (David Ahern) Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.

Otherwise it's just smaller fixes and cleanups to other drivers. There was a major conflict in mt76 driver between wireless-drivers and wireless-drivers-next. I solved that by merging the former to the latter. Major changes: rtw88 * add support for ieee80211_ops::change_interface * add support for enabling and disabling beacon * add debugfs file for testing h2c mt76 * ARP filter offload for 7663 * runtime power management for 7663 * testmode support for mfg calibration * support for more channels ==================== Signed-off-by: David S.

They also need to take care of configuration registers. With improved and powerful support of generic PM, PCI Core takes care of above mentioned, device-independent, jobs. The callbacks make use of PCI helper functions like pci_save/restore_state(), pci_enable/disable_device() and pci_set_power_state() to do required operations. In generic mode, they are no longer needed. Change function parameter in both .suspend() and .resume() to "struct device*" type. Use dev_get_drvdata() to get drv data. The .suspend() callback is invoking rt2x00lib_suspend() which needs to be modified as generic rt2x00pci_suspend() has no pm_message_t type argument, passed to it, which is required by it according to its declaration. Although this variable remained unused in the function body. Hence, remove it from the function definition & declaration. rt2x00lib_suspend() is also invoked by rt2x00usb_suspend() and rt2x00soc_suspend(). Thus, modify the functional call accordingly in their function body. Earlier, .suspend() & .resume() were exported and were used by the following drivers: - drivers/net/wireless/ralink/rt2x00/rt2400pci.c - drivers/net/wireless/ralink/rt2x00/rt2500pci.c - drivers/net/wireless/ralink/rt2x00/rt2800pci.c - drivers/net/wireless/ralink/rt2x00/rt61pci.c Now, we only need to bind "struct dev_pm_ops" variable to "struct pci_driver". Thus, make the callbacks static. Declare an "extern const struct dev_pm_ops" variable and bind PM callbacks to it. Now, export the variable instead and use it in respective drivers. Compile-tested only.

While RTL8822C series are WiFi + BT combo chips, it needs the co-existence mechanism for the device to work on both WiFi and BT without interfering each other. And the coex support has already been added before, most of the mechanisms are implemented. The driver should just add corresponding functions to operate on different types of chips and its coex parameters.

That will cause the coex mechanism being skipped unexpectedly. Coex only wanted to keep the TDMA table from being changed by BT side. So, check the freeze and reason, if the coex reason is coming from BT info, skip it, to make sure the coex triggered by Wifi itself can work. This is required for the AP mode, while the control flow is different with STA mode. When starting an AP mode, the AP mode needs to start working immedaitely after leaving IPS, and the freeze flag could be raised. If the coex info is skipped, then the AP mode will not set the antenna owner, leads to TX stuck.

And for ps-poll packets in reserved page, to prevent AID being changed by hardware, NAVUSEHDR should be set. Additionally, the rate should be adjusted based on the current band for mgmt and reserved page packets.
