Well, instead of the stock Kconfig.hz we maybe should use our own like
this:
config MACH_DECSTATION
bool
select SYS_SUPPORT_128HZ
select SYS_SUPPORT_256HZ
select SYS_SUPPORT_1024HZ
config MACH_JAZZ
bool "Support for the Jazz family of machines"
select SYS_SUPPORT_100HZ
...
config MACH_CUCUBER
...
...
choice
config HZ_48
bool "48Hz" if SYS_SUPPORT_48HZ
help
Useful for debugging of Linux on extremly slow hardware simulators.
...
config HZ_100
bool "100Hz" if SYS_SUPPORT_100HZ
help
blah
...
config HZ_128
bool "128Hz" if SYS_SUPPORT_128HZ
...
config HZ_250
bool "250Hz" if SYS_SUPPORT_250HZ
...
config HZ_256
bool "256Hz" if SYS_SUPPORT_256HZ
...
config HZ_1000
bool "1000Hz" if SYS_SUPPORT_1000HZ
...
config HZ_1024
bool "1024Hz" if SYS_SUPPORT_1024HZ
...
endchoice
config HZ
int
default 48 if HZ_48
default 100 if HZ_100
default 128 if HZ_128
default 250 if HZ_250
default 256 if HZ_256
default 1000 if HZ_1000
default 1024 if HZ_1024
What do you think?
Ralf
