| * | platform/x86: wmi: Use devres to disable the WMI deviceArmin Wolf2025-02-241-9/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use devm_add_action_or_reset() to disable the WMI device instead of manually calling wmi_method_enable() to prepare for future changes inside the WMI data block handlign code. The reason for this is that we have to make sure that all devres-managed resources are released first because some might still want to access the underlying WMI device. Because devres-managed resources are not released during shutdown we still have to manually disable the WMI device in this case.

User-space applications can now change the current USB mode by writing to "usb_mode" sysfs entry, replacing the previous ioctl-based method. The embedded controller (EC) currently supports only entering USB4 mode and exiting all modes (including altmodes). Both of these operations trigger Data Reset Message, even if no USB Mode is active. Additionally, the patch exposes the USB modes supported by the port via "usb_capability" sysfs attribute.

We cannot simply do a "goto error;" because the amd_pmf_tee_init() cleanup calls tee_shm_free(dev->fw_shm_pool); and amd_pmf_tee_deinit() calls it as well leading to a double free. I have re-written this code to use an unwind ladder to free the allocations. Second, if amd_pmf_start_policy_engine() fails on every iteration though the loop then the code calls amd_pmf_tee_deinit() twice which is also a double free. Call amd_pmf_tee_deinit() inside the loop for each failed iteration. Also on that path the error codes are not necessarily negative kernel error codes. Set the error code to -EINVAL. There is a very subtle third bug which is that if the call to input_register_device() in amd_pmf_register_input_device() fails then we call input_unregister_device() on an input device that wasn't registered. This will lead to a reference counting underflow because of the device_del(&dev->dev) in __input_unregister_device(). It's unlikely that anyone would ever hit this bug in real life.

The latest PMF-TA version introduces new structures with OEM debug information and additional policy input conditions for evaluating the policy binary. Consequently, the shared memory size must be increased to ensure compatibility between the PMF driver and the updated PMF-TA. To do so, introduce the new PMF-TA UUID and update the PMF shared memory configuration to ensure compatibility with the latest PMF-TA version. Additionally, export the TA UUID. These updates will result in modifications to the prototypes of amd_pmf_tee_init() and amd_pmf_ta_open_session().
