* thunderbolt: Make bandwidth allocation mode function names consistentMika Westerberg2023-06-161-7/+8
| | | | | | | | | Make sure the DisplayPort bandwidth allocation mode function names are consistent with the existing ones, such as USB3. No functional changes. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
* thunderbolt: Add support for enhanced uni-directional TMU modeMika Westerberg2023-06-161-33/+42
| | | | | | | | | | | | This is new TMU mode introduced with the USB4 v2. This mode is simpler than the existing ones and allows all CL states as well. Enable this for all links where both side routers are v2 and keep the existing functionality for the v1 and earlier links. Currently only support the MedRes rate. We can add the HiFi rate later too if it turns out to be useful. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
* thunderbolt: Move constants related to NVM into nvm.cGil Fine2023-06-161-4/+0
| | | | | | | | | | Move constants related to NVM into nvm.c to make the code cleaner. Use a separate constant for USB4_DATA_DWORDS in usb4.c. No functional changes. Signed-off-by: Gil Fine <gil.fine@linux.intel.com> Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
* thunderbolt: Enable USB4 v2 PCIe TLP/DLLP extended encapsulationGil Fine2023-06-161-0/+2
| | | | | | | | | USB4 v2 spec introduces modified encapsulation of PCIe TLP and DLLP packets. This improves the PCIe tunneled traffic usage by reducing overhead. Enable this if both sides of the link support it. Signed-off-by: Gil Fine <gil.fine@intel.com> Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
* thunderbolt: Add support for USB4 v2 80 Gb/s linkGil Fine2023-06-161-5/+9
| | | | | | | | | | | | | USB4 v2 bumps the per-lane speed up to 40 Gb/s. Also the lanes are always bonded which gives 80 Gb/s symmetric link (and 120/40 Gb/s asymmetric). This updates the speed and width of routers and XDomain connections to support the Gen 4 link. For now we keep the link as is even if it is already asymmetric. While there make tb_port_set_link_width() static. Signed-off-by: Gil Fine <gil.fine@intel.com> Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>

* thunderbolt: Enable/disable sideband depending on USB4 port offline modeMika Westerberg2023-06-121-0/+5
| | | | | | | | | | | | | When USB4 port is in offline mode (this mean there is no device attached) we want to keep the sideband up to make it possible to communicate with the retimers. In the same way there is no need to enable sideband transactions when the USB4 port is not offline as they are already up. For this reason make the enabling/disabling depend on the USB4 port offline status. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
* thunderbolt: Initialize CL states from the hardwareMika Westerberg2023-06-091-0/+1
| | | | | | | In case the boot firmware enabled any of them, read the currently configured CL states and update the router structure accordingly. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
* thunderbolt: Switch CL states from enum to a bitmaskMika Westerberg2023-06-091-38/+16
| | | | | | | | | This is more natural and follows the hardware register layout better. This makes it easier to see which CL states we enable (even though they should be enabled together). Rename 'clx_mask' to 'clx' everywhere as this is now always bitmask. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
* thunderbolt: Move CLx support functions into clx.cMika Westerberg2023-06-091-9/+8
| | | | | | | | | | There really don't belong to switch.c so move them into their own file. As we do this rename the functions to match the conventions used elsewhere in the driver. No functional changes. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
* thunderbolt: Check valid TMU configuration in tb_switch_tmu_configure()Mika Westerberg2023-06-091-3/+2

* thunderbolt: Get rid of tb_switch_enable_tmu_1st_child()Mika Westerberg2023-06-091-2/+0
| | | | | | | | This is better to be part of the software connection manager flows in tb.c. Also name the new function tb_increase_tmu_accuracy() to match what it actually does. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
* thunderbolt: Drop useless 'unidirectional' parameter from ↵Mika Westerberg2023-06-091-6/+4
| | | | | | | | | | | | tb_switch_tmu_is_enabled() There is no point passing it as we already have a field for that. While there clean up the kernel-doc of things that do not really belong to the API documentation (these can be figured out from the spec itself). No functional changes.

* thunderbolt: Introduce tb_switch_downstream_port()Gil Fine2023-06-091-0/+14
| | | | | | | | | | | | | Introduce tb_switch_downstream_port() helper function that returns the downstream port of a parent switch that is connected to the upstream port of specified switch. From now on, we use it all across the driver where applicable. While there fix a whitespace in comment and rename 'downstream' to 'down' to be consistent with the rest of the driver.

| | | | | | | | | | Current Intel USB4 host routers have hardware limitation that the USB3 bandwidth cannot go higher than 16376 Mb/s. Work this around by adding a new quirk that limits the bandwidth for the affected host routers.

* thunderbolt: Add missing UNSET_INBOUND_SBTX for retimer accessGil Fine2023-03-131-0/+1
| | | | | | | | | | | | | | | | | | | | According to USB4 retimer specification, the process of firmware update sequence requires issuing a SET_INBOUND_SBTX port operation that later shall be followed by UNSET_INBOUND_SBTX port operation. This last step is not currently issued by the driver but it is necessary to make sure the retimers are put back to passthrough mode even during enumeration. If this step is missing the link may not come up properly after soft-reboot for example. For this reason issue UNSET_INBOUND_SBTX after SET_INBOUND_SBTX for enumeration and also when the NVM upgrade is run.

There's a lot of changes this development cycle, most of the work falls into two different categories: - fw_devlink fixes and updates. This has gone through numerous review cycles and lots of review and testing by lots of different devices. Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall. This is the contuation of that work (started last release with kobject changes) in moving struct bus_type to be constant. We didn't quite make it for this release, but the remaining patches will be finished up for the release after this one, but the groundwork has been laid for this effort. Other than that we have in here: - debugfs memory leak fixes in some subsystems - error path cleanups and fixes for some never-able-to-be-hit codepaths. - cacheinfo rework and fixes - Other tiny fixes, full details are in the shortlog All of these have been in linux-next for a while with no reported problems" [ Geert Uytterhoeven points out that that last sentence isn't true, and that there's a pending report that has a fix that is queued up - Linus ] * tag 'driver-core-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (124 commits) debugfs: drop inline constant formatting for ERR_PTR(-ERROR) OPP: fix error checking in opp_migrate_dentry() debugfs: update comment of debugfs_rename() i3c: fix device.h kernel-doc warnings dma-mapping: no need to pass a bus_type into get_arch_dma_ops() driver core: class: move EXPORT_SYMBOL_GPL() lines to the correct place Revert "driver core: add error handling for devtmpfs_create_node()" Revert "devtmpfs: add debug info to handle()" Revert "devtmpfs: remove return value of devtmpfs_delete_node()" driver core: cpu: don't hand-override the uevent bus_type callback. devtmpfs: remove return value of devtmpfs_delete_node() devtmpfs: add debug info to handle() driver core: add error handling for devtmpfs_create_node() driver core: bus: update my copyright notice driver core: bus: add bus_get_dev_root() function driver core: bus: constify bus_unregister() driver core: bus: constify some internal functions driver core: bus: constify bus_get_kset() driver core: bus: constify bus_register/unregister_notifier() driver core: remove private pointer from struct bus_type ...

* | thunderbolt: Add support for DisplayPort bandwidth allocation modeMika Westerberg2023-01-171-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB4 spec defines an optional feature that allows the connection manager to negotiate with the graphics through DPCD registers changes in the bandwidth allocation dynamically. This is referred as "bandwidth allocation mode" in the spec. The connection manager uses DP IN adapters registers to communicate with the graphics, and also gets notifications from these adapters when the graphics wants to change the bandwidth allocation. Both the connection manager and the graphics driver needs to support this. We check if the DP IN adapter supports this and if it does enable it before establishing a DP tunnel. Then we react on DP_BW notifications coming from the DP IN adapter and update the bandwidth allocation accordingly (within the maximum common capabilities the DP IN/OUT support).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | As there will be more USB4 devices that support NVM firmware upgrade from various vendors, it makes sense to split out the Intel specific NVM image handling from the generic code. This moves the Intel specific NVM handling into a new structure that will be matched by the device type and the vendor ID. Do this for both routers and retimers.

| * thunderbolt: Change TMU mode to HiFi uni-directional once DisplayPort tunneledGil Fine2022-06-061-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | Here we configure TMU mode to HiFi uni-directional once DP tunnel is created. This is due to accuracy requirement for DP tunneling as appears in CM guide 1.0, section 7.3.2. Due to Intel hardware limitation, once we changed the TMU mode to HiFi uni-directional (when DP tunnel exists), we don't change TMU mode back to normal uni-directional, even if DP tunnel is torn down later.

| * thunderbolt: Add CL1 support for USB4 and Titan Ridge routersGil Fine2022-06-061-22/+24
| | | | | | | | | | | | | | | | | | | | | | | | In this patch we add support for a second low power state of the link: CL1. Low power states (called collectively CLx) are used to reduce transmitter and receiver power when a high-speed lane is idle. We enable it, if both sides of the link support it, and only for the first hop router (i.e. the first device that connected to the host router). This is needed for better thermal management.

* | thunderbolt: test: Use kunit_test_suite() macroDavid Gow2022-07-111-8/+0
|/ | | | | | | | | | | | | | | | | | | | The new implementation of kunit_test_suite() for modules no longer conflicts with module_init, so can now be used by the thunderbolt tests. Also update the Kconfig entry to enable the test when KUNIT_ALL_TESTS is enabled. This means that kunit_tool can now successfully run and parse the test results with, for example: ./tools/testing/kunit/kunit.py run --arch=x86_64 \ --kconfig_add CONFIG_PCI=y --kconfig_add CONFIG_USB4=y \ 'thunderbolt' Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com> Acked-by: Daniel Latypov <dlatypov@google.com> Acked-by: Brendan Higgins <brendanhiggins@google.com> Signed-off-by: David Gow <davidgow@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
* thunderbolt: Split setting link width and lane bonding into own functionsMika Westerberg2022-05-051-0/+2
| | | | | | | | | | | | | When bonding lanes over XDomain the host that has "higher" UUID triggers link re-train for bonding, and the host that has "lower" UUID just waits for this to happen. To support this split setting the link width and triggering the actual bonding a separate functions that can be called as needed.

* thunderbolt: Tear down existing tunnels when resuming from hibernateMika Westerberg2021-12-071-1/+4
| | | | | | | | | | | | | If the boot firmware implements connection manager of its own it may not create the paths in the same way or order we do. For example it may create first PCIe tunnel and then USB3 tunnel. When we restore our tunnels (first de-activating them) we may be doing that over completely different tunnels and that leaves them possibly non-functional. For this reason we re-use the tunnel discovery functionality and find out all the existing tunnels, and tear them down. Once that is done we can restore our tunnels.
