Hello list, I've a kiosk computer named arbor m1526 (http://www.arbor.com.tw/products/detail.aspx?Product_Name=M1526.) this hardware has some functions key (F1-F8) that are connected to Embedded Controller. The company do not provide Linux support to these buttons but provided information on addresses as follows: EC RAM Address 0x0501 Bit0 = 1 indicative F1 Button be pressed Bit1 = 1 indicative F2 Button be pressed Bit2 = 1 indicative F3 Button be pressed Bit3 = 1 indicative F4 Button be pressed Bit4 = 1 indicative F5 Button be pressed Bit5 = 1 indicative F6 Button be pressed Bit6 = 1 indicative F7 Button be pressed Bit7 = 1 indicative F8 Button be pressed P.S. If read finish please clear EC ram bit flag. I would like to write a new acpi patch/file to the linux kernel for supporting these buttons. seems to me that the right place is writing a new file at drivers/platform/x86 I'm looking for some good doc. or template for writing a new hardware acpi support. any help will be appreciate, tnx, --Y -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
