Summary: radeonfb backlight config mismatch
Product: Drivers
Version: 2.5
KernelVersion: 2.6.25.4
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: low
Priority: P1
Component: Console/Framebuffers
AssignedTo: jsimmons at infradead.org
ReportedBy: gokdenizk at gmail.com
Distribution: Gentoo
Hardware Environment: ATI Technologies Inc RS300M AGP [Radeon Mobility 9100IGP]
Problem Description:
In the radeon framebuffer driver, drivers/video/aty/radeon_base.c
CONFIG_PMAC_BACKLIGHT is used to enable/disable backlight support. But in the
config file generated by 'menuconfig', CONFIG_FB_RADEON_BACKLIGHT is used for
this purpose, PMAC is for Macintosh. This mismatch prevents compilation of
radeonfb without backlight support.
The exact lines from Linux Torvalds' git tree as of now
drivers/video/aty/radeon_base.c:
279 #ifdef CONFIG_PMAC_BACKLIGHT
280 static int backlight = 1;
281 #else
282 static int backlight = 0;
283 #endif
Should be
279 #ifdef CONFIG_FB_RADEON_BACKLIGHT
I tested a kernel build with this change applied.
