16 years agoxen64: fix calls into hypercall page
Jeremy Fitzhardinge [Tue, 8 Jul 2008 22:06:37 +0000 (15:06 -0700)]
xen64: fix calls into hypercall page

The 64-bit calling convention for hypercalls uses different registers
from 32-bit.  Annoyingly, gcc's asm syntax doesn't have a way to
specify one of the extra numeric reigisters in a constraint, so we
must use explicitly placed register variables.  Given that we have to
do it for some args, may as well do it for all.

Also fix syntax gcc generates for the call instruction itself.  We
need a plain direct call, but the asm expansion which works on 32-bit
generates a rip-relative addressing mode in 64-bit, which is treated
as an indirect call.  The alternative is to pass the hypercall page
offset into the asm, and have it add it to the hypercall page start
address to generate the call.

16 years agoxen: add xen_arch_resume()/xen_timer_resume hook for ia64 support

xen: add xen_arch_resume()/xen_timer_resume hook for ia64 support

add xen_timer_resume() hook.

Timer resume should be done after event channel is resumed.
add xen_arch_resume() hook when ipi becomes usable after resume.
After resume, some cpu specific resource must be reinitialized
on ia64 that can't be set by another cpu.

However available hooks is run once on only one cpu so that ipi has
to be used.

During stop_machine_run() ipi can't be used because interrupt is masked.
So add another hook after stop_machine_run().
Another approach might be use resume hook which is run by
device_resume(). However device_resume() may be executed on
suspend error recovery path.

So it is necessary to determine whether it is executed on real resume path
or error recovery path.

we can remove the action argument in ide_do_drive_cmd and ide_action_t
typedef.

blk_rq_init before ide_do_drive_cmd so there is no need to initialize
rq->errors.
