2020-09-24platform/x86: intel-vbtn: Fix SW_TABLET_MODE always reporting 1 on the HP ↵Hans de Goede
Pavilion 11 x360 Commit cfae58ed681c ("platform/x86: intel-vbtn: Only blacklist SW_TABLET_MODE on the 9 / "Laptop" chasis-type") restored SW_TABLET_MODE reporting on the HP stream x360 11 series on which it was previously broken by commit de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet mode switch on 2-in-1's"). It turns out that enabling SW_TABLET_MODE reporting on devices with a chassis-type of 10 ("Notebook") causes SW_TABLET_MODE to always report 1 at boot on the HP Pavilion 11 x360, which causes libinput to disable the kbd and touchpad. The HP Pavilion 11 x360's ACPI VGBS method sets bit 4 instead of bit 6 when NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT collection shows only one other model, the Medion E1239T ever setting bit 4 and it always sets this together with bit 6. So lets treat bit 4 as a second bit which when set indicates the device not being in tablet-mode, as we already do for bit 6. While at it also prefix all VGBS constant defines with "VGBS_".

2020-09-24platform/x86: asus-nb-wmi: Revert "Do not load on Asus T100TA and T200TA"Hans de Goede
The WMI INIT method on for some reason turns on the camera LED on these 2-in-1s, without the WMI interface allowing further control over the LED. To fix this commit b5f7311d3a2e ("platform/x86: asus-nb-wmi: Do not load on Asus T100TA and T200TA") added a blacklist with these 2 models on it since the WMI driver did not add any extra functionality to these models. Recently I've been working on making more 2-in-1 models report their tablet-mode (SW_TABLET_MODE) to userspace; and I've found that these 2 Asus models report this through WMI. This commit reverts the adding of the blacklist, so that the Asus WMI driver can be used on these models to report their tablet-mode. I have another patch fixing the LED issue in a different manner. Note this is the second time the we revert the adding of the asus_nb_wmi_blacklist. It was reverted before in commit: aab9e7896ec9 ("platform/x86: asus-nb-wmi: Revert "Do not load on Asus T100TA and T200TA")" But some how (accidentally re-applying of the patch?) it got re-added again in commit 3bd12da7f50b ("platform/x86: asus-nb-wmi: Do not load on Asus T100TA and T200TA"), so now we need to revert it again.

2020-09-23net: dsa: b53: Configure VLANs while not filteringFlorian Fainelli
Update the B53 driver to support VLANs while not filtering. This requires us to enable VLAN globally within the switch upon driver initial configuration (dev->vlan_enabled). We also need to remove the code that dealt with PVID re-configuration in b53_vlan_filtering() since that function worked under the assumption that it would only be called to make a bridge VLAN filtering, or not filtering, and we would attempt to move the port's PVID accordingly. Now that VLANs are programmed all the time, even in the case of a non-VLAN filtering bridge, we would be programming a default_pvid for the bridged switch ports. We need the DSA receive path to pop the VLAN tag if it is the bridge's default_pvid because the CPU port is always programmed tagged in the programmed VLANs. In order to do so we utilize the dsa_untag_bridge_pvid() helper introduced in the commit before within net/dsa/tag_brcm.c.

Without this fix, turning on EEE using ethtool will return "Operation not supported". This is due to the driver is in a dead loop waiting for eee to be advertised in the for eee to be activated but the driver will only configure the EEE advertisement after the eee is activated.

While the switch driver is written such that port 5 or 8 could be CPU ports, the use case on Broadcom STB chips is to use port 8 exclusively. The platform firmware does make port 5 comply to a proper DSA CPU port binding by specifiying an "ethernet" phandle. This is undesirable for now until we have an user-space configuration mechanism (such as devlink) which could support dynamically changing the port flavor at run time.

2020-09-23Revert "ravb: Fixed to be able to unload modules"Geert Uytterhoeven
This reverts commit 1838d6c62f57836639bd3d83e7855e0ee4f6defc. This commit moved the ravb_mdio_init() call (and thus the of_mdiobus_register() call) from the ravb_probe() to the ravb_open() call. This causes a regression during system resume (s2idle/s2ram), as new PHY devices cannot be bound while suspended. During boot, the Micrel PHY is detected like this: Micrel KSZ9031 Gigabit PHY e6800000.ethernet-ffffffff:00: attached PHY driver [Micrel KSZ9031 Gigabit PHY] (mii_bus:phy_addr=e6800000.ethernet-ffffffff:00, irq=228) ravb e6800000.ethernet eth0: Link is Up - 1Gbps/Full - flow control off During system suspend, (A) defer_all_probes is set to true, and (B) usermodehelper_disabled is set to UMH_DISABLED, to avoid drivers being probed while suspended. A. If CONFIG_MODULES=n, phy_device_register() calling device_add() merely adds the device, but does not probe it yet, as really_probe() returns early due to defer_all_probes being set: dpm_resume+0x128/0x4f8 device_resume+0xcc/0x1b0 dpm_run_callback+0x74/0x340 ravb_resume+0x190/0x1b8 ravb_open+0x84/0x770 of_mdiobus_register+0x1e0/0x468 of_mdiobus_register_phy+0x1b8/0x250 of_mdiobus_phy_device_register+0x178/0x1e8 phy_device_register+0x114/0x1b8 device_add+0x3d4/0x798 bus_probe_device+0x98/0xa0 device_initial_probe+0x10/0x18 __device_attach+0xe4/0x140 bus_for_each_drv+0x64/0xc8 __device_attach_driver+0xb8/0xe0 driver_probe_device.part.11+0xc4/0xd8 really_probe+0x32c/0x3b8 Later, phy_attach_direct() notices no PHY driver has been bound, and falls back to the Generic PHY, leading to degraded operation: Generic PHY e6800000.ethernet-ffffffff:00: attached PHY driver [Generic PHY] (mii_bus:phy_addr=e6800000.ethernet-ffffffff:00, irq=POLL) ravb e6800000.ethernet eth0: Link is Up - 1Gbps/Full - flow control off B. If CONFIG_MODULES=y, request_module() returns early with -EBUSY due to UMH_DISABLED, and MDIO initialization fails completely: mdio_bus e6800000.ethernet-ffffffff:00: error -16 loading PHY driver module for ID 0x00221622 ravb e6800000.ethernet eth0: failed to initialize MDIO PM: dpm_run_callback(): ravb_resume+0x0/0x1b8 returns -16 PM: Device e6800000.ethernet failed to resume: error -16 Ignoring -EBUSY in phy_request_driver_module(), like was done for -ENOENT in commit 21e194425abd65b5 ("net: phy: fix issue with loading PHY driver w/o initramfs"), would makes it fall back to the Generic PHY, like in the CONFIG_MODULES=n case.

In addition, refactoring the tc ct api is introduced to make it agnostic to the flow type and perform the resource allocations and rule insertion to the proper steering domain in the device. In the initialization call, the api requests and stores in the ct database instance all the relevant information that distinguishes between nic flows and esw flows, such as chains database, steering namespace and mod hdr table. This way the operations of adding and removing ct flows to the device can later performed agnostically to the flow type.

2020-09-23net/mlx5e: rework ct offload init messagesAriel Levkovich
The changes are: - Use mlx5_core print macros instead of netdev_warn since netdev is not always initialized at that stage. - Print a warning message in case the issue is with lack of support for CT offload without indicating an error.

2020-09-23net/mlx5e: Add tc chains offload support for nic flowsAriel Levkovich
Allow adding nic tc flow rules with goto chain action. Connecting the nic flows to the mlx5 chains infrastructure in previous patches allows us to support the creation of chained flow tables and rules that direct to another chain for further packet processing. This is a required preparation to support CT offloads for nic tc flows. We allow the creation of 256 different chains for nic flows since we have 8 bits available for the chain restore tag in case of a miss.

2020-09-23net/mlx5: Refactor tc flow attributes structureAriel Levkovich
In order to support chains and connection tracking offload for nic flows, there's a need to introduce a common flow attributes struct so that these features can be agnostic and have access to a single attributes struct, regardless of the flow type. Therefore, a new tc flow attributes format is introduced to allow access to attributes that are common to eswitch and nic flows. The common attributes will always get allocated for the new flows, regardless of their type, while the type specific attributes are separated into different structs and will be allocated based on the flow type to avoid memory waste. When allocating the flow attributes the caller provides the flow steering namespace and according the namespace type the additional space for the extra, type specific, attributes is determined and added to the total attribute allocation size. In addition, the attributes that are going to be common to both flow types are moved to the common attributes struct.

2020-09-23net/mlx5e: Split nic tc flow allocation and creationAriel Levkovich
For future support of CT offload with nic tc flows, where the flow rule is not created immediately but rather following a future event, the patch is splitting the nic rule creation and deletion into 2 parts: 1. Creating/Deleting and setting the rule attributes. 2. Creating/Deleting the flow table and flow rule itself. This way the attributes can be prepared and stored in the flow handle when the tc flow is created but the rule can actually be created at any point in the future, using these pre allocated attributes.

2020-09-23net/mlx5e: Tc nic flows to use mlx5_chains flow tablesAriel Levkovich
Change nic tc flows offload path to use the chains and prios infrastructure for the flow table creation as a preparation to support tc multi chains and priorities for nic flows. Adding an instance of the table chaining database to the nic tc struct and perform the root table creation and desctuction via the chains api while keeping the limit of a single chain (0) in nic tc mode. This will be extendable to supporting multiple chains in the following patches. The flow table sizes and default miss table parameters that are provided to the chains creation api are kept the same.

2020-09-23net/mlx5: Refactor multi chains and prios supportAriel Levkovich
Decouple the chains infrastructure from eswitch and make it generic to support other steering namespaces. The change defines an agnostic data structure to keep all the relevant information for maintaining flow table chaining in any steering namespace. Each namespace that requires table chaining will be required to allocate such data structure. The chains creation code will receive the steering namespace and flow table parameters from the caller so it will operate agnosticly when creating the required resources to maintain the table chaining function while Parts of the code that are relevant to eswitch specific functionality are moved to eswitch files.
