Hi there!
I'm trying to modify msi_wmi driver to get it work with mediakeys on my MSI
GE60 laptop.
By default, I get "Unknown event received" message.
For now, I diagnosed that event, that every key press produces has 0x03 (
ACPI_TYPE_BUFFER?) type, instead of 0x01 (ACPI_TYPE_INTEGER) which in-kernel
msi_wmi module wants.
Further diagnostic with that code:
232 › } else if (obj && obj->type == ACPI_TYPE_BUFFER) {
233 › › int eventcode = obj->integer.value;
234 › › pr_info("Eventcode: 0x%x\n", eventcode);
235 › › key = sparse_keymap_entry_from_scancode(msi_wmi_input_dev,
236 › › › › eventcode);
237 › › if (!key) {
238 › › › pr_info("Unknown key pressed - %x\n", eventcode);
239 › › › goto msi_wmi_notify_exit;
240 › › }
241
242 › › pr_info("%d\n",key->type);
243 › } else
244 › › pr_info("Unknown event received\n");
(only patched part)
Gives me following info:
Wen I press on any of media-keys — I get the same eventcode (and every time I
get if(!key) error. Moreover, evencode value changes in time (something about
4 seconds), so, if I'll press some key many times, eventcode value will be
changed after 4s, but it will not change if I press another mediakeys.
Can anybody advice me, why can I experience such behaviour?
And is it a way to get mediakeys working without patching DSDT (last time I
did that I brake my bluetooth module in that way, that even rfkill was unable
to enable it :P)?
