C++ (Cpp) tls_preserve_current_state Examples

Example #1

File: process.c Project: 150balbes/Amlogic_s905-kernel

static void tls_thread_switch(struct task_struct *next)
{
	tls_preserve_current_state();

	if (is_compat_thread(task_thread_info(next)))
		write_sysreg(next->thread.uw.tp_value, tpidrro_el0);
	else if (!arm64_kernel_unmapped_at_el0())
		write_sysreg(0, tpidrro_el0);

	write_sysreg(*task_user_tls(next), tpidr_el0);
}

Example #2

File: process.c Project: EMFPGA/linux_media

{
	unsigned long tpidr, tpidrro;

	tls_preserve_current_state();

	tpidr = *task_user_tls(next);
	tpidrro = is_compat_thread(task_thread_info(next)) ?
		  next->thread.tp_value : 0;

	write_sysreg(tpidr, tpidr_el0);
	write_sysreg(tpidrro, tpidrro_el0);
}
