* 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
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.
* This was a script relying on a working /etc/profile, which may not be
there
* Instead, use GNU which, available as an haikuport recipe
* Since the command does not seem to be needed for Haiku to run (and
also because I don't know how to do it), GNU which isn't in the default
install.
* Typing "which" in a terminal still works, as that uses an alias
defined directly in /etc/profile.
Declare a HOST_PTHREAD_LINKFLAGS variable to hold the flags
required to link with pthreads, and use it for the solver addon.
Works on GNU/Linux, please test and fix for other platforms.
* only the source package are actually relevant, as the source paths
within older versions of those source packages no longer match the
expectations of the build system
Latest gcc converts the old ones to the new ones anyway...
including when passing to gas, which of course is not new enough,
so we have to also force gcc to pass the old one around in one case.
Since the PM merge we now have way too many targets,
here jam clean just fails in execve() due to too long arguments.
jam clean is now very verbose but at least it works.
Another option could be to override the Clean rule itself
to clean in batch by splitting the list...
Patches welcome.
Both for the rPI and the Verdex target we now have FDTs. The verdex
DTS is homebrew, the pxa DTSIs come from Linux and should be kept
in sync.
The rPI DTS and Broadcom DTSI come from FreeBSD HEAD, and should
ofcourse also be kept in sync.
One global new Jam rule has been introduced for handling DTS
compilation, aptly named CompileDTS....
More coming!
This is especially important for the assembler code in the kernel,
since it enables workarounds for some critical errata related to
exception handling.
This adds the -mapcs-frame compiler flag for ARM to have "stable"
stack frames, adds support to the kernel for dumping stack crawls,
and initial support for iframes. There' much more functionality
to unlock in KDL, but this makes debugging already a lot more
comfortable.....
The symlink was only correct, if the container was a package. For
containers with a non-empty path to the system directory the link would
duplicate the system directory path.
