search for: late_time_init

The time_init_hook in paravirt-ops no longer functions in the correct manner after the integration of the hrtimers code. The problem is that now the call path for time initialization is: time_init : late_time_init = hpet_time_init; late_time_init -> hpet_time_init: setup_pit_timer (BAD) do_time_init --> (via paravirt.h) time_init_hook --> (via arch_hooks.h) time_init_hook (in SUBARCH/setup.c) If this isn't confusing enough, the paravirt case goes through...

Hi, This series corresponds do older patches in the paravirt series that was neither already applied, nor I will touch again. In general, they do not touch code that can be unified (at least, without being the unification a big problem on its own). They passed through this list a lot of times, so I feel them ready for inclusion, unless someone opposes. As with the other patches, they apply to

Matt attempted to add CLOCK_TAI support to the VDSO clock_gettime() implementation, which extended the clockid switch case and added yet another slightly different copy of the same code. Especially the extended switch case is problematic as the compiler tends to generate a jump table which then requires to use retpolines. If jump tables are disabled it adds yet another conditional to the existing

Hi. This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was sent as another patchest. This patchset does the followings. - Some preparation work. Mainly importing header files to define related structures. - Then, define functions related to hypercall which is the way to communicate with Xen hypervisor. - Add some helper functions which is necessary to

Hi. This patchset is ia64/xen domU patch take 8 which was updated following Tony's review. (Thank you very much, Tony.) This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was sent as another patchest. This patchset is for linux ia64 test branch and depends on some patches for xen common part I'll send separately. To compile, the changesets in x86/xen
