platform/x86/amd/hsmp: Check HSMP support on AMD family of processors

2024-06-03T09:57:28Z

HSMP interface is supported only on few x86 processors from AMD. Accessing HSMP registers on rest of the platforms might cause unexpected behaviour. So add a check. Also unavailability of this interface on rest of the processors is not an error. Hence, use pr_info() instead of the pr_err() to log the message.

platform/x86: dell-smbios: Simplify error handling

2024-06-03T09:54:29Z

When the allocation of value_name fails, the error handling code uses two gotos for error handling, which is not necessary. Simplify the error handling in this case by only using a single goto. Tested on a Dell Inspiron 3505.

platform/x86: dell-smbios: Fix wrong token data in sysfs

2024-06-03T09:53:54Z

When reading token data from sysfs on my Inspiron 3505, the token locations and values are wrong. This happens because match_attribute() blindly assumes that all entries in da_tokens have an associated entry in token_attrs. This however is not true as soon as da_tokens[] contains zeroed token entries. Those entries are being skipped when initialising token_attrs, breaking the core assumption of match_attribute(). Fix this by defining an extra struct for each pair of token attributes and use container_of() to retrieve token information. Tested on a Dell Inspiron 3050.

platform/x86: touchscreen_dmi: Add support for setting touchscreen properties from cmdline

2024-05-27T09:42:57Z

On x86/ACPI platforms touchscreens mostly just work without needing any device/model specific configuration. But in some cases (mostly with Silead and Goodix touchscreens) it is still necessary to manually specify various touchscreen-properties on a per model basis. touchscreen_dmi is a special place for DMI quirks for this, but it can be challenging for users to figure out the right property values, especially for Silead touchscreens where non of these can be read back from the touchscreen-controller. ATM users can only test touchscreen properties by editing touchscreen_dmi.c and then building a completely new kernel which makes it unnecessary difficult for users to test and submit properties when necessary for their laptop / tablet model. Add support for specifying properties on the kernel commandline to allow users to easily figure out the right settings. See the added documentation in kernel-parameters.txt for the commandline syntax.
