Hi! > [ Upstream commit 0b178b02673998f5acca5a0365a8858ca45beedb ] > > 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. I don't believe this is suitable for stable.
