This series addresses the following issues:
- Add proper error handling to uncore and rapl drivers
- Get rid of the pseudo per cpuness of these drivers and do a proper per
package storage
- Allow them to be modular
In order to do proper per package storage I added a facility which sanity
checks the physical package id of the processors which is supplied by bios and
does a logical package id translation. That allows drivers to do allocations
for the maximum number of possible packages independent of possible BIOS
creativity.
Changes vs. V1:
- Add logical package management
- Drop the exit_box callbacks for modern processors. This needs to be
revisited on a case by case basis.
- Fixup and convert the rapl driver as well
Thanks,
tglx
