2024-01-02HID: hid-steam: Add gamepad-only mode switched to by holding optionsVicki Pfau
This commit adds a hotkey to switch between "gamepad" mode (mouse and keyboard disabled) and "desktop" mode (gamepad disabled) by holding down the options button (mapped here as the start button). This mirrors the behavior of the official Steam client. This also adds and uses a function for generating haptic pulses, as Steam also does when engaging this hotkey.

SDL includes a list of settings (formerly called registers in this driver), reports (formerly cmds), and various other identifiers that were provided by Valve.

The client_opened variable was used to track if the hidraw was opened by any clients to silence keyboard/mouse events while opened. However, there was no counting of how many clients were opened, so opening two at the same time and then closing one would fool the driver into thinking it had no remaining opened clients.

2024-01-02HID: hid-steam: Clean up lockingVicki Pfau
This cleans up the locking logic so that the spinlock is consistently used for access to a small handful of struct variables, and the mutex is exclusively and consistently used for ensuring that mutliple threads aren't trying to send/receive reports at the same time. Previously, only some report transactions were guarded by this mutex, potentially breaking atomicity. The mutex has been renamed to reflect this usage.

2024-01-02thermal/drivers/exynos: Use set_trips opsMateusz Majewski
Currently, each trip point defined in the device tree corresponds to a single hardware interrupt. This commit instead switches to using two hardware interrupts, whose values are set dynamically using the set_trips callback. Additionally, the critical temperature threshold is handled specifically. Setting interrupts in this way also fixes a long-standing lockdep warning, which was caused by calling thermal_zone_get_trips with our lock being held. Do note that this requires TMU initialization to be split into two parts, as done by the parent commit: parts of the initialization call into the thermal_zone_device structure and so must be done after its registration, but the initialization is also responsible for setting up calibration, which must be done before thermal_zone_device registration, which will call set_trips for the first time; if the calibration is not done in time, the interrupt values will be silently wrong!

2024-01-02thermal/drivers/exynos: Stop using the threshold mechanism on Exynos 4210Mateusz Majewski
Exynos 4210 supports setting a base threshold value, which is added to all trip points. This might be useful, but is not really necessary in our usecase, so we always set it to 0 to simplify the code a bit. Additionally, this change makes it so that we convert the value to the calibrated one in a slightly different place. This is more correct morally, though it does not make any change when single-point calibration is being used (which is the case currently).

2024-01-02thermal/thermal_of: Allow rebooting after critical tempFabio Estevam
Currently, the default mechanism is to trigger a shutdown after the critical temperature is reached. In some embedded cases, such behavior does not suit well, as the board may be unattended in the field and rebooting may be a better approach. The bootloader may also check the temperature and only allow the boot to proceed when the temperature is below a certain threshold. Introduce support for allowing a reboot to be triggered after the critical temperature is reached. If the "critical-action" devicetree property is not found, fall back to the shutdown action to preserve the existing default behavior. If a custom ops->critical exists, then it takes preference over critical-actions.

2024-01-02dt-bindings: thermal-zones: Document critical-actionFabio Estevam
Document the critical-action property to describe the thermal action the OS should perform after the critical temperature is reached. The possible values are "shutdown" and "reboot". The motivation for introducing the critical-action property is that different systems may need different thermal actions when the critical temperature is reached. For example, in a desktop PC, it is desired that a shutdown happens after the critical temperature is reached. However, in some embedded cases, such behavior does not suit well, as the board may be unattended in the field and rebooting may be a better approach. The bootloader may also benefit from this new property as it can check the SoC temperature and in case the temperature is above the critical point, it can trigger a shutdown or reboot accordingly.

2024-01-01net: qrtr: ns: Return 0 if server port is not presentSarannya S
When a 'DEL_CLIENT' message is received from the remote, the corresponding server port gets deleted. A DEL_SERVER message is then announced for this server. As part of handling the subsequent DEL_SERVER message, the name- server attempts to delete the server port which results in a '-ENOENT' error. The return value from server_del() is then propagated back to qrtr_ns_worker, causing excessive error prints. To address this, return 0 from control_cmd_del_server() without checking the return value of server_del(), since the above scenario is not an error case and hence server_del() doesn't have any other error return value.

2024-01-01Merge branch 'phy-listing-link_topology-tracking'David S. Miller
Maxime Chevallier says: ==================== Introduce PHY listing and link_topology tracking Here's a V5 of the multi-PHY support series. At a glance, besides some minor fixes and R'd-by from Andrew, one of the thing this series does is remove the ASSERT_RTNL() from the topo_add_phy/del_phy operations. These operations will take a PHY device and put it into the list of devices associated to a netdevice. The main thing to protect here is the list itself, but since we use xarrays, my naive understanding of it is that it contains its own protection scheme. There shouldn't be a need for more locking, as the insertion/deletion paths are already hooked into the PHY connection to a netdev, or disconnection from it. Now for the rest of the cover : As a remainder, this ongoing work aims ultimately at supporting complex link topologies that involve multiplexing multiple PHYs/SFPs on a single netdevice. As a first step, it's required that we are able to enumerate the PHYs on a given ethernet interface. By just doing so, we also improve already-existing use-cases, namely the copper SFP modules support when a media-converter is used (as we have 2 PHYs on the link, but only one is referenced by net_device.phydev, which is used on a variety of netlink commands). The series is architectured as follows : - The first patch adds the notion of phy_link_topology, which tracks all PHYs attached to a netdevice. - Patches 2, 3 and 4 adds some plumbing into SFP and phylib to be able to connect the dots when building the topology tree, to know which PHY is connected to which SFP bus, trying not to be too invasive on phylib. - Patch 5 allows passing a PHY_INDEX to ethnl commands. I'm uncertain about this, as there are at least 4 netlink commands ( 5 with the one introduced in patch 7 ) that targets PHYs directly or indirectly, which to me makes it worth-it to have a generic way to pass a PHY index to commands, however the approach taken may be too generic. - Patch 6 is the netlink spec update + ethtool-user.c|h autogenerated code update (the autogenerated code triggers checkpatch warning though) - Patch 7 introduces a new netlink command set to list PHYs on a netdevice. It implements a custom DUMP and GET operation to allow filtered dumps, that lists all PHYs on a given netdevice. I couldn't use most of ethnl's plumbing though. - Patch 8 is the netlink spec update + ethtool-user.c|h update for that new command - Patch 8,9,10 and 11 updates the PLCA, strset, cable-test and pse netlink commands to use the user-provided PHY instead of net_device.phydev. - Finally patch 12 adds some documentation for this whole work. Examples ======== Here's a short overview of the kind of operations you can have regarding the PHY topology. These tests were performed on a MacchiatoBin, which has 3 interfaces : eth0 and eth1 have the following layout: MAC - PHY - SFP eth2 has this more classic topology : MAC - PHY - RJ45 finally eth3 has the following topology : MAC - SFP When performing a dump with all interfaces down, we don't get any result, as no PHY has been attached to their respective net_device : None The following output is with eth0, eth2 and eth3 up, but no SFP module inserted in none of the interfaces : [{'downstream-sfp-name': 'sfp-eth0', 'drvname': 'mv88x3310', 'header': {'dev-index': 2, 'dev-name': 'eth0'}, 'id': 0, 'index': 1, 'name': 'f212a600.mdio-mii:00', 'upstream-type': 'mac'}, {'drvname': 'Marvell 88E1510', 'header': {'dev-index': 4, 'dev-name': 'eth2'}, 'id': 21040593, 'index': 1, 'name': 'f212a200.mdio-mii:00', 'upstream-type': 'mac'}] And now is a dump operation with a copper SFP in the eth0 port : [{'downstream-sfp-name': 'sfp-eth0', 'drvname': 'mv88x3310', 'header': {'dev-index': 2, 'dev-name': 'eth0'}, 'id': 0, 'index': 1, 'name': 'f212a600.mdio-mii:00', 'upstream-type': 'mac'}, {'drvname': 'Marvell 88E1111', 'header': {'dev-index': 2, 'dev-name': 'eth0'}, 'id': 21040322, 'index': 2, 'name': 'i2c:sfp-eth0:16', 'upstream': {'index': 1, 'sfp-name': 'sfp-eth0'}, 'upstream-type': 'phy'}, {'drvname': 'Marvell 88E1510', 'header': {'dev-index': 4, 'dev-name': 'eth2'}, 'id': 21040593, 'index': 1, 'name': 'f212a200.mdio-mii:00', 'upstream-type': 'mac'}] -- Note that this shouldn't actually work as the 88x3310 PHY doesn't allow a 1G SFP to be connected to its SFP interface, and I don't have a 10G copper SFP, so for the sake of the demo I applied the following modification, which of courses gives a non-functionnal link, but the PHY attach still works, which is what I want to demonstrate : @@ -488,7 +488,7 @@ static int mv3310_sfp_insert(void *upstream, const struct sfp_eeprom_id *id) if (iface != PHY_INTERFACE_MODE_10GBASER) { dev_err(&phydev->mdio.dev, "incompatible SFP module inserted\n"); - return -EINVAL; + //return -EINVAL; } return 0; } Finally an example of the filtered DUMP operation that Jakub suggested in V1 : [{'downstream-sfp-name': 'sfp-eth0', 'drvname': 'mv88x3310', 'header': {'dev-index': 2, 'dev-name': 'eth0'}, 'id': 0, 'index': 1, 'name': 'f212a600.mdio-mii:00', 'upstream-type': 'mac'}, {'drvname': 'Marvell 88E1111', 'header': {'dev-index': 2, 'dev-name': 'eth0'}, 'id': 21040322, 'index': 2, 'name': 'i2c:sfp-eth0:16', 'upstream': {'index': 1, 'sfp-name': 'sfp-eth0'}, 'upstream-type': 'phy'}] And a classic GET operation allows querying a single PHY's info : {'drvname': 'Marvell 88E1111', 'header': {'dev-index': 2, 'dev-name': 'eth0'}, 'id': 21040322, 'index': 2, 'name': 'i2c:sfp-eth0:16', 'upstream': {'index': 1, 'sfp-name': 'sfp-eth0'}, 'upstream-type': 'phy'} Changed in V5: - Removed the RTNL assertion in the topology ops - Made the phy_topo_get_phy inline - Fixed the PSE-PD multi-PHY support by re-adding a wrongly dropped check - Fixed some typos in the documentation - Fixed reverse xmas trees Changes in V4: - Dropped the RFC flag - Made the net_device integration independent to having phylib enabled - Removed the autogenerated ethtool-user code for the YNL specs Changes in V3: - Added RTNL assertions where needed - Fixed issues in the DUMP code for PHY_GET, which crashed when running it twice in a row - Added the documentation, and moved in-source docs around - renamed link_topology to phy_link_topology Changes in V2: - Added the DUMP operation - Added much more information in the reported data, to be able to reconstruct precisely the topology tree - renamed phy_list to link_topology ==================== Signed-off-by: David S.
