Thomas Gleixner a6825f1c1f x86: hpet: workaround SB700 BIOS ... AMD SB700 based systems with spread spectrum enabled use a SMM based HPET emulation to provide proper frequency setting. The SMM code is initialized with the first HPET register access and takes some time to complete. During this time the config register reads 0xffffffff. We check for max. 1000 loops whether the config register reads a non 0xffffffff value to make sure that HPET is up and running before we go further. A counting loop is safe, as the HPET access takes thousands of CPU cycles. On non SB700 based machines this check is only done once and has no side effects. Based on a quirk patch from: crane cai <crane.cai@amd.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>		2008-08-14 13:23:45 +02:00
