Subject: [Adeos-main] task_hijacked, prepare_arch_switch and irq disabling
Date: Mon, 09 Nov 2009 14:00:15 +0100 [thread overview]
Message-ID: <4AF8125F.60009@domain.hid> (raw)
Hi Philippe,
a customer just stumbled over some unclear spots in current I-pipe patches:
Why is there local_irq_enable_hw in task_hijacked? Looks like it was
once paired with prepare_arch_switch, but that call is now only used by
legacy 2.4 PPC. Can we safely drop it from all other patches (it's in
the context switch fast-path...)? Moreover, I bet the
ENABLE_INTERRUPTS_HW_COND in entry_32.S' ret_from_fork is related to
this as well, right?
