[Bug 596641] Re: mbp-nvidia-bl: adding support for MacBook Pro 7, 1
max_level=44000 seems to be a good approximation of the maximal value...
Is there any real risk setting a too high value? (i.e. could my laptop take fire? =))

Bug description:
MacBook Pro 7,1 has a nvidia chipset (MCP89 / graphics: Geforce 320 M)
I tried to add the following lines into mbp_nvidia_bl.c:
{
.callback = mbp_dmi_match,
.ident = "MacBookPro 7,1",
.matches = {
DMI_MATCH(DMI_SYS_VENDOR, "Apple Inc."),
DMI_MATCH(DMI_PRODUCT_NAME, "MacBookPro7,1"),
},
.driver_data = (void *)&nvidia_chipset_data,
},
At bootup,
$ cat /sys/class/backlight/mbp_backlight/brightness
15
but,
$ echo 3 > /sys/class/backlight/mbp_backlight/brightness
does nothing on the brightness, except that
$ cat /sys/class/backlight/mbp_backlight/brightness
3
If you need some command line outputs, I can provide them.
Thanks
