sys/kern subr_hints.c
Log:
MFC 1.12 (by netchild)
| The resource_xxx routines in subr_hints.c are called before and after the
| kenv environment in kern_environment.c switches to dynamic kenv. The prior
| call sets the static variable hintp to the static hints in subr_hints.c
| (hintmode==0).
|
| However, changes to the environment are not detected by the resource_xxx
| lookups after the change to dynamic kernel environment, so the lookup
| routines only report the old stuff of hintmode==0, even after the change to
| the dynamic kenv. This causes kenv users to see a different environment than
| the kernel routines.
|
| This is a problem in the mixer.c code that looks up initial mixer volume
| settings from the hints: If the hints are dynamic and not from the
| device.hints file, mixer.c doesn't see them, but kenv does.
|
| The patch from the PR (modified to comply to the style of the function)
| solves this.
