The introduction of secondary arch support for kernel files disabled
-Werror for all kernel files, since the -Werror flags were moved from
{CC,C++}FLAGS to TARGET_WARNING_{CC,C++}FLAGS_<arch>, which, however,
was overwritten by the SetupKernel rule. This commit introduces new
global variables {HAIKU,HOST,TARGET}_WERROR_FLAGS[_<arch>], which
contain the additional -Werror flags to be applied for the architecture.
The config variable WARNINGS can be set to "treatAsErrors" to cause
-Werror and {HOST,TARGET}_WERROR_FLAGS[_<arch>] to be appended to the
compilation flags.
Fixes #10280.
* Create new interface for cpuidle modules (similar to the cpufreq
interface)
* Generic cpuidle module is no longer needed
* Fix and update Intel C-State module
Somehow gcc doesn't detect the linker is GNU ld when run in Haikuporter.
We now force this in the recipe. This allows gcc to invoke the linker
with response files, avoiding "command line too long" errors, for
example when building WebKit.
* Fix adding WebPositive optional package.
* Fix adding wonderbrush package. Add it only for gcc2 to avoid a
warning by AddHaikuImagePackages.
* Simplify adding xz_utils package.
* Add rule HaikuRepository to build a repository from a repository info
file and a list of package files. It calls a build_haiku_repository
script which does all the work.
* Add target <repository>haiku for building the Haiku package
repository.
It should be built via "jam -q @alpha-raw build <repository>haiku";
the build profile is only needed to activate all build features.
We can't reliably set contemporary processors to an arbitrary frequency.
There are dependencies between cores and thechnologies like Turbo Boost
which may make actual frequency significantly different than the requested.
Moreover, it is the scheduler job to decide how much CPU performance is
needed and user shouldn't interfere with that.
In current state this driver is useless anyway. It's not MP safe.
The P-state values stored in hardcoded tables are only for processors
on which we can't use SpeedStep, because of lack of invariant TSC.
Proper driver should get P-states from ACPI, ensure that the CPU offers
invariant TSC and obviouslt be MP safe.
