* [PATCH] x86_64: Automatically enable apicmaintimer on ATI boardsAndi Kleen2006-02-041-0/+8
| | | | | | | | | They all have problems with IRQ 0 routing, so just use the APIC on them. Can be overwritten with "noapicmaintimer" Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] x86_64: Allow to run main time keeping from the local APIC interruptAndi Kleen2006-02-045-9/+83
| | | | | | | | | | | | | | | | | | | | | | Another piece from the no-idle-tick patch. This can be enabled with the "apicmaintimer" option. This is mainly useful when the PIT/HPET interrupt is unreliable. Note there are some systems that are known to stop the APIC timer in C3. For those it will never work, but this case should be automatically detected. It also only works with PM timer right now. When HPET is used the way the main timer handler computes the delay doesn't work. It should be a bit more efficient because there is one less regular interrupt to process on the boot processor. Requires earlier bugfix from Venkatesh Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * [PARISC] Arch-specific compat signalsKyle McMartin2006-01-226-14/+232
| | | | | | | | | | | | | | | | | | | | Add enough arch-specific compat signals code to enable parisc64 to compile and boot out of the mainline tree. There are likely still many dragons here, but this is a start to squashing the last big difference between the mainline tree and the parisc-linux tree.

| | | | | | | | | | | | | | | | | | | | | | | | | | Define a chassis_power_off routine that machines which have a way to turn off the power supply can hook into. Formerly they were using pm_power_off, which is now being used by generic code. Make lasi.c use chassis_power_off instead of pm_power_off.

| * | [SERIAL] initialize spinlock for port failed to setup consoleAtsushi Nemoto2006-02-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems serial_core intend to initialize port->lock just once for each ports. This is done in uart_set_options() for console, and in uart_add_one_port() for other ports. But there is a case the port->lock is not initialized by serial_core. If the setup function for the console was failed, it will not call uart_set_options() but the port is marked as console (uart_console(port) returns 1). It can happen if console was PCI port which can not detected at the time of register_console. This patch is to initialize port->lock for such console port. With this change, most of spin_lock_init() (some of them are labeled "Temporary fix.") in low-level serial drivers can be omitted.
