The ACPI EC that is used in MSI laptops knows some non-standard commands for changing the screen brighntess and a few other things, which are used by the msi-laptop.c driver. Unfortunately for these commands no GPE events for IBF and OBF are triggered. Since nowadays the EC code uses the ec_intr=1 mode by default, this causes these operations to timeout, although they don't fail. In result, all operations that you can do with the msi-laptop.c driver take more or less 1s to complete, which is awfully slow. In one of the more recent kernels (2.6.20?) the EC subsystem has been revamped. With that change the EC timeout has been increased. before that increase the MSI EC accesses were slow -- but not *that* slow, hence I took notice of this limitation of the MSI EC hardware only very recently. The standard EC operations on the MSI EC as defined in the ACPI spec support GPE events properly. The following patch adds a new argument "force_poll" to the ec_transaction() function (and friends). If set to 1, the function will poll for IBF/OBF even if ec_intr=1 is enabled. If set to 0 the current behaviour is used. The msi-laptop driver is modified to make use of this new flag, so that OBF/IBF is polled for the special MSI EC transactions -- but only for them.
